方法 Method

技术领域 FIELD

[0001] 本发明涉及提供全局连接性的通信网络技术。 [0001] The present invention relates to provide global connectivity of a communication network technology.

背景技术 BACKGROUND

[0002] 目前,因特网已发展至在固定网络节点系统的周围部署众多外部数据通信网络的阶段。 [0002] Currently, the Internet has developed to the deployment phase of the plurality of external data communication networks around the fixed network nodes of the system. 把这些数据通信网络相应地称为边缘网络,同时把边缘网络所环绕的固定网络节点系统称为核心网络。 These data communication networks accordingly called edge networks, while the fixed network nodes surrounded by the edge of the network system called the core network. 随着无线技术的出现与发展,越来越多这样的边缘网络在使用无线方案,从而形成了一种称为移动网络,或移动中的网络的特殊边缘网络(参见以下的非专利文献1)。 With the advent and development of wireless technology, more and more such programs using a wireless network edge, thus forming a special edge network called a mobile network, or the mobile network (see the following Non-Patent Document 1) .

[0003] 实质上,移动网络是一种其中整个网络不断改变其与因特网的附接点的节点网络。 [0003] In essence, a mobile network wherein the network node of the network changing its point of attachment to the Internet. 这通常需要在不同存取路由器(事实上,它们本身也是可移动的)之间不断改变其与因特网的附接点的移动网络中的移动路由器(其把移动网络与因特网加以桥接)。 This typically requires changing between different access router (in fact, they are themselves movable) its mobile network to the Internet attachment point of a mobile router (which the mobile network and the Internet to bridge). 移动网络的例子包括附接于人的网络(称为个人区域网,即PAN)和部署在诸如汽车、火车、轮船或飞机的运载工具中的传感器的网络。 Examples include mobile network attached to the person's network (called personal area networks, namely PAN) and deployed in vehicles such as cars, trains, ships or aircraft in sensor networks. 对于诸如飞机、火车或公共汽车的大型运输系统,操作人员可能会向乘客提供允许乘客使用他们的膝上机、个人数字助手(PDA)或移动电话与远程主机相连的持久性乘坐时的因特网访问。 For such large transport system plane, train or bus, the operator may provide to passengers allow passengers to use their laptops, personal digital assistants (PDA) or mobile phone connected to a remote host with Internet access when persistent ride . 通常,这样的移动网络中的个体节点连接到一中心设备(即移动路由器),而且当网络移动时不改变它们的附接。 Typically, such a mobile network node is connected to a central individual devices (i.e. mobile router), and when the mobile network do not change their attachment. 取而代之,当网络整体移动时,移动路由器改变其附接点。 Instead, when the overall mobile network, the mobile router changes its point of attachment.

[0004] 实质上,移动中的网络之问题在于,向整体移动的网络中的节点提供连续的因特网连接性。 [0004] In essence, the problem of the moving network is to provide continuous Internet connectivity to the whole network in a mobile node. 移动的网络中的节点可能不知道网络在改变其与因特网的附接点。 The mobile nodes in the network may not know the network changes its point of attachment to the Internet. 这不同于因特网协议第4版(IPv4)(参见以下的非专利文献3)中的Mobile IPv4(参见以下的非专利文献2)和因特网协议第6版(Ipv6)(参见以下的非专利文献5)中的Mobile IPv6 (参见以下的非专利文献4)所涉及的传统的移动性支持问题。 This differs from an Internet Protocol version 4 (IPv4) (see the following Non-Patent Document 3) in the Mobile IPv4 (see the following Non-Patent Document 2) and the Internet Protocol version 6 (Ipv6) (see the following Non-Patent Document 5 ) in Mobile IPv6 (see the following Non-Patent Document 4) Traditional mobility support issues involved. 在非专利文献2和4中,主要目的是向个体主机,而不是向整个网络提供移动性支持。 In Non-Patent Document 2 and 4, the main purpose is to an individual host, rather than to provide mobility support to the entire network.

[0005] 在Mobile IP中,每个移动节点具有持久性家乡域(home domain)。 [0005] In Mobile IP, each mobile node has a persistent home domain (home domain). 当把移动网络附接于其家乡网络时,其被赋予了称为家乡地址的主全局地址。 When the mobile network attached to its home network, which was given the primary global address known as the home address. 当移动网络离开时,即当将其附接于其它外地(foreign)网络时,通常向其赋予称为转交地址(care-of-address)的临时全局地址。 When leaving the mobile network, ie when it is attached to the other field (foreign) network, commonly referred to as care-of address (care-of-address) confer upon him a temporary global address. 移动性支持的概念是,甚至是当把移动节点附接于其它外地网络时,也可以根据家乡地址到达移动节点。 Concept of mobility support is even when the mobile node is attached to other foreign network, you can also reach the mobile node based on the home address. 非专利文献2和4中通过引入了称为家乡代理的家乡网络处的实体而实现了这一点。 NPL 2 and 4 by introducing an entity known as the home network at the home agent while achieving this. 移动节点使用称为绑定更新(Bingding Update)的消息,向家乡代理登记它们的转交地址。 Mobile nodes called binding update (Bingding Update) message to the home agent to register their care-of address. 家乡代理负责拦截对移动节点的家乡地址进行寻址的消息,并且使用IP-in-IP(IP中IP)隧道(Tunnelling)(参见以下的非专利文献6和7)将分组转发到移动节点的转交地址。 Home agent responsible for the interception of the home address of the mobile node addressing the message, and the use of IP-in-IP (IP in IP) tunnel (Tunnelling) (see the following non-patent literature 6 and 7) will forward the packet to the mobile node care-of address. IP-in-IP隧道涉及把一个原始IP分组封装于另一个IP分组中。 IP-in-IP tunneling involves the one of the original IP packet is encapsulated in another IP packet. 有时,把原始分组称为内部分组,把封装内部分组的新分组称为外部分组。 Sometimes called the original packet inside a packet, the new packet encapsulated inside packets called external packet. [0006] 由于把针对个体主机的移动性支持的概念扩展至针对节点网络的移动性支持,所以移动中网络方案的目的是提供这样一种机制:其中,可以根据移动网络中的节点的主全局地址到达该节点,而无论把移动网络附接于因特网上的何处。 [0006] Due to the concept of mobility support for individual hosts extended to mobility support for nodes in the network, so the purpose of the program is moving in the network to provide such a mechanism: where you can master the global mobile network nodes address reaches the node, regardless of the mobile network is attached to where the Internet. 存在一些解决移动中的网络的问题的尝试,它们全都是基于Mobile (移动)IP的(参见非专利文献3和4)。 There are some problems to solve in the mobile network attempts, they are all based on Mobile (Mobile) IP (see Non-Patent Documents 3 and 4). [0007] 以下的专利文献1中给出了用于移动中的网络的一种提议方案。 [0007] The following Patent Document 1 proposes a scheme proposed for moving networks. 此处,当控制移动网络的移动路由器处于其家乡域中时,其使用某些路由协议执行对至移动网络和来自移动网络的分组的路由。 Here, when the mobile router controlling a mobile network is in its home domain, using some routing protocols perform routing to the mobile network and a packet from the mobile networks. 当移动路由器及其移动网络移动至一个外地域时,移动路由器向其家乡代理登记其转交地址。 When the mobile router and the mobile network to move to a foreign domain, the mobile router with its home agent registers its care-of address. 然后,在移动路由器和家乡代理之间建立IP-in-IP隧道。 Then, the establishment of IP-in-IP tunneling between the mobile router and the home agent. 也在IP-in-IP隧道上执行当移动路由器处于其家乡域时所使用的路由协议。 When the routing protocol to perform a mobile router in its home domain is also used on the tunnel IP-in-IP. 这意味着家乡代理将拦截去往移动网络的每一分组,并且通过IP-in-IP隧道将它们转发到移动路由器。 This means that the home agent will intercept packets destined for each mobile network, and through IP-in-IP tunnel to forward them to the mobile router. 移动路由器然后把分组转发到其移动网络中的主机。 The mobile router then forwards the packet to its mobile network host. 当其移动网络中的一个节点希望把分组发送于网络之外时,移动路由器拦截该分组,并且将通过IP-in-IP隧道把该分组转发到家乡代理。 When one of its mobile network node wishes to send a packet outside the network, the mobile router intercepts the packet and by IP-in-IP tunneling to the packet is forwarded to the home agent. 家乡代理然后把该分组发出至意欲的接收方。 Home agent then put the packet issued to the intended recipient.

[0008] 以下的专利文献2中所公开的另一种方案除了其特别陈述对IPv6(参见非专利文献5)的支持之外大体上相似。 [0008] Alternatively the following Patent Document 2 disclosed except that it specifically stated support for the outside of IPv6 (see Non-Patent Document 5) are substantially similar.

[0009] 已知各种无线技术(即蓝牙、IEEE 802. 11a/b/g、超宽带、红外、通用分组射频服务),不难想像这样一种情况:其中,存在着嵌套的移动网络,即一个移动网络处于另一个移动网络之中。 [0009] Known wireless technologies (i.e. Bluetooth, IEEE 802. 11a / b / g, Ultra Wideband, Infrared, General Packet Radio Service), it is easy to imagine a case: where there is a nested mobile network that in the midst of a mobile network to another mobile network. 使用专利文献l中所建议的方案,这引发了称为往复路由(Ping-pong routing)或嵌套的隧道的问题。 Patent Document l in the proposed program, which raises the question called reciprocating routing (Ping-pong routing) or nested tunnels. 嵌套的隧道是这样一种情况:其中,一个移动路由器与其家乡代理所建立的隧道被封装在另一个移动路由器与其家乡代理所建立的另一个隧道中。 Nested tunnel is such a case: where a mobile router and its home agent tunnels established another tunnel is encapsulated in another mobile router and its home agent established in. 隧道的嵌套将导致分组经过的时间的增加,因为分组在抵达其最终目的地之前,需要访问一个以上的家乡代理。 Nested tunnel packet will result in an increase of the elapsed time since the packet before reaching its final destination, need access to more than one home agent. 另外,多个封装也增大了分组的大小,从而导致了不必要的断片化(fragmentation)。 Further, a plurality of packaging also increases the size of the packet, resulting in the unnecessary fragment of (fragmentation).

[0010] 为了解决这一问题,以下的非专利文献8中所建议的另一种方案涉及对反路由头标(Reverse Routing Header)的使用,以便避免当移动网络嵌套(即一个移动网络把其自己附接于另一个移动网络)时具有太多的封装层。 Alternatively [0010] To solve this problem, the following Non-Patent Document 8 relates to the use of the proposed anti-routing header (Reverse Routing Header) in order to avoid nesting when the mobile network (i.e. a mobile network to encapsulation layer having its own too attached to another mobile network) when. 此处,最低层移动网络在到其家乡代理的其隧道分组中建立一个反路由头标。 Here, the lowest level of the mobile network to establish an anti-tunnel routing header in its packet to its home agent's. 当高层移动路由器在其途中拦截到这一分组时,该更高层移动路由器并不把这一分组封装于另一个IP-in-IP隧道。 When a high-level mobile router in its way to intercept the packet, the router does not move to a higher level in this group is encapsulated in another IP-in-IP tunneling. 取而代之,该高层移动路由器把该分组中的源地址拷贝至反路由头标中,并且将其自己的转交地址置为源地址。 Instead, the high-level mobile router to the packet's source address is copied to the anti-routing header, and the care of its own address as the source address. 在这一方式下,当第一移动路由器的家乡代理接收到这一分组时,其可以确定处于第一移动路由器和其本身之间的路径中的移动路由器链。 In this way, when the first mobile router home agent receives this packet, it may be determined in a path between the first mobile router and itself between the mobile router chain. 接下来,当该家乡代理希望针对第一移动路由器转发另一个所拦截的分组时,它可以包括一个扩展的2型路由头标,以便可以经由其它高层移动路由器把该分组直接发送至第一移动路由器。 Next, when the home agent would be to address the first mobile router to forward another intercepted packet, it can include an extended type 2 routing header, so that you can put the mobile router via other high-level the packet is sent directly to the first mobile routers.

[0011] 安全是非专利文献8中的反路由头标方案的一个主要问题。 [0011] Non-Patent Document 8 security is a major issue anti-routing header solution. 以下的非专利文献9 针对嵌套的隧道优化问题,建议了一种相对安全的方案。 The following non-patent literature 9 for nested tunnel optimization problem, proposed a relatively safe option. 这一方案,称为访问路由器选项(Access Router Option,AR0)方案,在Mobile IPv6中所规定的移动性头标中定义了一个新的选项。 This program, called the Access Router Option (Access Router Option, AR0) solutions, mobility in Mobile IPv6 header as specified in the definition of a new option. 该新选项,称为访问路由器选项,被发送方(即移动路由器或移动主机)使用,以把发送方所附接到的访问路由器的主全局地址通知接收方(例如家乡代理或对方节点)。 The new option, called access router option, is the sender (ie mobile router or mobile host) used in order to master the global address of the sender of the attached access router received a notification recipient (such as a home agent or the other node). 发送了具有访问路由器选项的绑定更新消息之后,接下来,移动节点可以把一个称为"直接转发请求(direct-forwarding-request)"信号的特殊信号插入到其发出的数据分组。 After sending the binding update message with the access router option, Next, the mobile node can be called "Direct Forwarding Request (direct-forwarding-request)" signal is a special signal is inserted into data packets which it is issued. 这一信号将导致上游移动访问路由器把其自己的绑定更新发送于目的地地址。 This signal will cause the upstream mobile access router to send its own binding update to the destination address. 重复这一过程,直至抵达最顶层移动访问路由器。 Repeat this process until you reach the topmost mobile access router. 通过所有上游移动访问路由器向目的地发送绑定更新,该目的地可以建造移动节点所附接的移动访问路由器的链。 By all upstream mobile access router sends a binding update to the destination, which can build an attached mobile node chain mobile access router. 这可用于构造扩展的2型路由头标,因此,当目的地节点希望向移动节点发回一个分组时,它可以向该分组嵌入路由头标,该分组将经由移动访问路由器链而被直接路由到移动节点。 This can be used to construct the extended Type 2 routing header, and therefore, when the mobile node to the destination node wishes to send back a packet, it can be embedded in the routing header to the packet, the packet will be routed directly via the mobile access router chain to the mobile node.

[0025] 发送方获知其访问路由器的主全局地址的方式是通过访问路由器所广播的广告消息。 Way [0025] The sender informed of their access to the router's primary global address is advertising messages broadcast by accessing the router. 非专利文献10中规定了路由器广告。 Non-Patent Document 10 provides a router advertisement. 在非专利文献9中,支持这一方案的访问路由器必须主动地在其发出至其入口(ingress)的路由器广告中广播其出口(egress interface)的其主全局地址。 9 non-patent literature in support of this program to access the router must take the initiative to issue to its entrance (ingress) router advertisement broadcast its exit (egress interface) of its primary global address in its. 以下,把含有主全局地址的路由器广告中的信息称为"访问路由器地址信息(Access-Router-Address-Information),,或简称为"ARA-Info"。这样一来, 附接到访问路由器的入口的移动节点将获知访问路由器的主全局地址,并且发现访问路由器支持AR0方案。[0026] 当存在位于内侧移动节点和外侧移动路由器之间的介入局部路由器时,这一设置存在问题。图l中对此进行了说明。在图1中,移动节点1000-1附接于局部固定路由器1100-1。局部固定路由器1100-1持久性地连接到移动访问路由器1200-1。通常在诸如火车或轮船的大型交通载体中可以看到这种部署模式,其中,移动访问路由器用于提供火车/ 轮船对全局因特网的访问。把连接到移动访问路由器的局部固定路由器部署在火车/轮船的每个车厢/船舱中,以向每一车厢/船舱提供无线连接。作为移动主机的膝上机(或无线PAN中的PDA,作为针对无线PAN的移动路由器),可以附接于这些局部固定路由器之一。 [0027] 这样的一种部署模式,形成了局部固定路由器驻留在移动节点和移动访问路由器之间的状况。由于局部固定路由器1100-1持久性地连接到移动访问路由器1200-1,所以其不需要拥有或理解移动性协议。其简单地对去往和来自移动节点1000-1和移动访问路由器1200-1的分组进行路由。因此,局部固定路由器将不使用与移动性相关的协议,这意味着局部固定路由器1100-1所发送的路由器广告将不包含其自己的主全局地址。 [0028] 网络部署的这一配置,将导致ARO方案的失败,因为局部固定路由器1100-1所广播的路由器广告将不包含任何ARA-Info。另外,即使移动访问路由器1200-1所发送的路由器广告将把其自己主全局地址包含于ARA-Info中,移动节点1000-1也将不能接收到这样的广告。这是因为仅可在一跳(hop)内发送路由器广告,而且按IPv6协议操作的所有路由器都不转发路由器广告。 Below, the router advertisement containing the primary global address information as "access router address information (Access-Router-Address-Information) ,, or simply" ARA-Info ". As a result, access to the router attached Entrance will be informed of the mobile nodes to access the router's main global address, and access routers support AR0 find solutions. [0026] When the involvement of local routers exist on the inside and outside of the mobile nodes move between routers, there is a problem with this setup. Figure l This is described in. In Figure 1, the mobile node 1000-1 is attached to the local fixed router 1100-1. local fixed router 1100-1 persistently connected to the mobile access router 1200-1. Typically, such as a train or Large transport carrier ship can be seen in this deployment model, which is used to provide mobile access router train / boat access to the global Internet. The mobile access router is connected to a local fixed router deployed at the train / ship of each compartment / cabin in order to provide wireless connectivity to each car / cabin. As a mobile host laptops (or wireless PAN in the PDA, as a mobile router for the wireless PAN), may be attached to one of these local fixed routers. [0027] Such a deployment pattern, forming a local fixed router residing in status between the mobile node and the mobile access router. Since the local fixed router 1100-1 persistently connected to the mobile access router 1200-1, so its not need to have or understand mobility protocols. Its simply for packets to and from the mobile node 1000-1 and the mobile access router 1200-1 will be routed. Therefore, the local fixed router will not use mobility related protocol, which means local fixed router 1100-1 transmitted router advertisement will not contain its own primary global address. This arrangement [0028] network deployment will cause the ARO program failure, because the local fixed router 1100-1 is broadcast Router Advertisement does not contain any ARA-Info. Further, even if the mobile access router 1200-1 will sent its own router advertisement containing the primary global address in the ARA-Info, the mobile node 1000-1 will be unable to receive such advertising. This is because the router can send advertisements only in hops (hop) inside, and all routers do not operate according to the IPv6 protocol router forwarding advertising.

[0029] —种显而易见的方案是,使得所有部署在移动网络中的局部固定路由器支持ARO 方案。 [0029] - species obvious solution is to make all local fixed router deployed in a mobile network supporting ARO solution. 然而,这样做具有其缺陷。 However, this has its drawbacks. 首先,这意味着失去了与传统的路由器的兼容性。 First, it means losing compatibility with legacy routers. 其次, 通过在不改变其附接点的路由器上支持整套ARO方案(这是一种移动性协议),不必要地增大了系统的复杂度。 Secondly, by supporting the ARO program package (which is a mobility protocol) on without changing its point of attachment routers, unnecessarily increasing the complexity of the system. 这转化为更高的开发成本和更高的维护成本。 This translates to higher development costs and higher maintenance costs.

发明内容 SUMMARY

[0030] 本发明通过在每一包含的实施例中规定4种不同的方法,增强了AR0方案。 [0030] The present invention is by four different methods specified in each embodiment included in the enhanced AR0 program. 第一种方法是移动节点1000-1在其发出的绑定更新消息中嵌入特殊标记。 The first method is the mobile node 1000-1 to embed special markings in the binding update message sent in its. 移动访问路由器1200-1将扫描这样的信号,从而知道发送方正试图发现移动访问路由器。 Mobile access router 1200-1 will scan such a signal, so they know to send Founder trying to find mobile access router. 移动访问路由器1200-1然后把其主全局地址告诉发送方。 Mobile access router 1200-1 then its primary global address to the sender.

[0031] 第二种方法是移动访问路由器1200-1彻底扫描所有进入的分组,以寻找移动节点1000-1所发送的绑定更新消息。 [0031] The second method is completely mobile access router 1200-1 to scan all incoming packets to look for the mobile node 1000-1 sent binding update messages. 因为移动节点1000-1正在使用AR0方案,所以在绑定更新消息中设置了特殊比特。 Because the mobile node 1000-1 is using AR0 scheme, so set up a special bit in the binding update message. 移动访问路由器1200-1将知道,发送方支持ARO方案,但不知道其访问路由器的主全局地址。 Mobile access router 1200-1 will know that the sender supports the ARO solution, but I do not know the primary global address of its access router. 移动访问路由器1200-1然后把其主全局地址告诉发送方。 Mobile access router 1200-1 then its primary global address to the sender.

[0032] 第三种方法是,移动节点1000-1把特殊分组发送于其上游中的所有路由器。 [0032] A third approach is to move all the routers in the upstream node 1000-1 to send its special grouping. 当接 When connected

收到这一分组时,支持ARO方案的路由器将答复以它们的主全局地址。 Upon receiving this packet, the router supports the ARO program will reply with their primary global address.

[0033] 最后一种方法是,部署局部固定路由器1100-1,以便其将具有其所连接到的移动 [0033] The last method is to deploy the local fixed router 1100-1, it will have to move so that it is connected to

访问路由器的主全局地址的ARA-info嵌入到局部固定路由器1100-1自身发送的路由器广 ARA-info to access the router's main global address embedded into the local fixed router 1100-1 router sends its own wide

告消息中。 Report message.

[0034] 本发明使得,即使局部固定路由器驻留在形成移动网络的移动访问路由器和连接于这一移动网络的移动节点之间,也能够向移动节点和移动网络提供全局连接性。 [0034] The present invention enables, even when the local fixed router resides in between the mobile access router forming a mobile network and the mobile node connected to this mobile network, it is possible to provide the global connectivity to the mobile node and the mobile network. 附图说明 Brief Description

[0056] 在以下的描述中,为了便于解释,给出了具体的数字、时间、结构以及其它参数,以提供对本发明的全面了解。 [0056] In the following description, for purposes of explanation, specific numbers, times, structures, and other parameters, in order to provide a thorough understanding of the present invention. 然而,对本领域中的任何技术人员将会很清楚,可以在不使用这些具体细节的情况下,实践本发明。 However, one skilled in the art will clear any, may be the case without using these specific details, the practice of the present invention. [0057]〈第一实施例> [0057] <First Embodiment>

[0058] 本发明的第一实施例描述了这样一种情况:当一个移动节点发出绑定更新消息时,使用一个嵌入在分组头标中的特殊标记。 [0058] The first embodiment of the present invention describe a situation: When a mobile node sends binding update messages, use embedded in a packet header in the special markers. 在检测到这样一个特殊标记时,上游移动访问路由器将把其HoA通知移动节点。 Upon detecting such a special mark, upstream mobile access router will notify its HoA mobile node.

[0059] 图1说明了其中可以部署本发明的移动节点与全局数据通信网络的系统。 [0059] Figure 1 illustrates the present invention can be deployed where the mobile node and the global data communication network system. 把移动节点1000-1附接于局部固定路由器1100-1。 The mobile node 1000-1 is attached to the local fixed router 1100-1. 把局部固定路由器1100-1本身附接于移动访问路由器1200-1。 The local fixed router 1100-1 itself attached to the mobile access router 1200-1. 注意,为了简单起见,仅描述了附接于移动访问路由器1200-1的一个局部固定路由器1100-1,并且仅描述了附接于局部固定路由器1100-1的一个移动节点1000-1。 Note that, for simplicity, only describes the mobile access router is attached to a local fixed router 1200-1 of 1100-1, 1100-1 and described only a mobile node attached to a local fixed router 1000-1. 在实际的部署中,可能存在附接于移动访问路由器1200-1的任意数目的局部固定路由器1100-1,以及附接于这些局部固定路由器1100-1任何之一的任意数目的移动节点1000-1。 In an actual deployment, there may be attached to any number of mobile access router 1200-1 in local fixed router 1100-1, and attached to these local fixed routers 1100-1 in any one of any number of mobile node 1000- 1. 对本领域中的任何技术人员应很清楚,本发明也将适合于这样的情况。 For any technique in the art should clearly, the present invention will also suitable for such a case. [0060] 而且,关于移动节点1000-1是移动主机还是移动路由器,并未给出任何规定。 [0060] Moreover, with regard to the mobile node 1000-1 is a mobile host or a mobile router, did not give any rules. 事实上,其本身也可以为移动访问路由器1200-1。 Indeed, which itself can be a mobile access router 1200-1. 对术语"移动节点"的特意使用,旨在不失一般性。 Specifically the use of the term "mobile node" is intended without loss of generality. 术语"移动节点"既代表移动主机,也代表移动路由器。 The term "mobile node" represents both a mobile host, but also on behalf of the mobile router. 本领域中的任何技术人员也应清楚,本发明既适合于移动节点1000-1为移动主机时的情况,也适合于移动节点1000-1为移动(访问)路由器时的情况。 Any skilled in the art will also be apparent, the present invention is not only suitable for the mobile host to the case when the mobile node 1000-1, the mobile node 1000-1 is also suitable for a case where the mobile (access) router when.

[0061] 另外,尽管在移动节点1000-1和移动访问路由器1200-1之间的路径中示出了一 [0061] Further, although in the path 1000-1 and the mobile access router 1200-1 in between the mobile node shows a

个局部固定路由器iioo-i,但实际上可能存在串行连接在移动节点1000-1和移动访问路 A local fixed router iioo-i, but in fact there may be a serial connection of the mobile node 1000-1 and the mobile access road

由器1200-1之间的多个这样的局部固定路由器1100-1。 By a plurality of devices 1200-1 between such local fixed routers 1100-1. 本领域中的任何技术人员应意识到,本发明同样适用于使用移动节点1000-1和移动访问路由器1200-1之间有一或多个局部固定路由器1100-1的情况。 Any skilled in the art should recognize that the present invention is equally applicable to the case of using the mobile node has one or more local fixed routers 1100-1 in between 1000-1 and the mobile access router 1200-1.

[0062] 把移动访问路由器1200-1附接于全局数据通信网络1600-1。 [0062] The mobile access router 1200-1 attached to the global data communication network 1600-1. 这一网络1600-1可以为任何分组交换网络,或者实际上是因特网本身。 This network 1600-1 can be any packet-switched network, or the Internet itself is actually. 附接于全局数据通信网络1600-1的是家乡代理1400-1和1400-2,它们分别用作移动节点1000-1和移动访问路由器1200-1的家乡代理。 Attached to the global data communication network is the home agent 1600-1 1400-1 and 1400-2, which are used as a mobile node 1000-1 and 1200-1 mobile access router home agent. 持久性地附接于移动访问路由器1200-1的局部固定路由器1100-1,不具有移动性协议,从而不需要家乡代理。 Persistent attached to the mobile access router of the local fixed router 1200-1 1100-1, does not have mobility protocol and thus does not require the home agent. 对方节点1500-1为具有与移动节点1000-1的正在进行的业务会话的全局数据通信网络1600-1上的任何节点(或者在其中移动节点1000-1为移动访问路由器的情况下,为在移动节点1000-1之后的任何移动节点)。 The other node 1500-1 is any node (or in the case where the mobile node 1000-1 is a mobile access router if global data communication network 1600-1 on the mobile node 1000-1 is having an ongoing service session, as in Any mobile node after the mobile node 1000-1).

[0063] 当移动节点1000-1首次启动时,其从局部固定路由器1100-1接收路由器广告消息。 [0063] When the mobile node 1000-1 first starts, its 1100-1 receiving router advertisement message from the local fixed router. 然后,移动节点1000-1根据路由器广告中所承载的前缀信息,配置其自身的CoA。 Then, the mobile node 1000-1 in the prefix information carried in the router advertisement, configure its own CoA. 接下来,移动节点1000-1需要通过向家乡代理1400-1和对方节点1500-1发送BU消息而将要被绑定到其HoA的新CoA通知它们。 Next, the mobile node 1000-1 needs to inform them of the home agent 1400-1 and 1500-1 the other node sends BU message to be bound to the HoA of its new CoA. 由于局部固定路由器1100-1所发送的路由器广告不包含任何ARA-Info,所以移动节点1000-1在其发出的BU消息中不能包括任何访问路由器选项。 Because of the local fixed router 1100-1 sent router advertisements do not contain any ARA-Info, the mobile node 1000-1 can not include any access router option in the BU message it sent in. 取而代之,移动节点1000-1把一个特殊标记嵌入BU消息的分组头标中,以指示后继的上游移动访问路由器应答复以它们的HoA。 Instead, the mobile node 1000-1 to embed a special marker packet header of the BU message, to indicate subsequent upstream mobile access routers should respond with their HoA. 为了易于解释,以下把这样的标记称为"访问路由器地址请求(Access-Router-Address-Request)"信号,或縮写为"ARA-Req"。 For ease of explanation, below the mark so called "access router address request (Access-Router-Address-Request)" signal, or abbreviated as "ARA-Req". ARA-Req 可以呈特定比特或比特流的形式。 ARA-Req may take the form of a specific bit or bit stream. 例如,在IPv6中,存在着一称为路由器警告选项的逐跳(hop-by-hop)选项(参见非专利文献ll)。 For example, in IPv6, there is an option called a router warning hop (hop-by-hop) option (cf. ll). 该特殊标记可以采取路由器警告选项中的特定值的形式。 This special marking may take the form of a router alert option in the specific value.

[0064] 局部固定路由器1100-1接收分组,并且在确认分组为有效之后,其把分组上游转发于移动访问路由器1200-1。 [0064] the local fixed router 1100-1 receives the packet, and after confirming the effective grouping, which forwards the packet upstream to the mobile access router 1200-1. 移动访问路由器1200-1将针对任何嵌入的信号例如ARA-Req,检查来自其一或多个入口的进入分组。 Mobile access router 1200-1 for example ARA-Req, checking incoming packet from one or more inlets for any embedded signals. 当检测到ARA-Req时,除了对进入分组的正常处理外,移动访问路由器1200-1还需要采取特定的动作。 When detecting the ARA-Req, in addition to the normal processing of incoming packets, the mobile access router 1200-1 need to take a particular action. 首先,移动访问路由器1200-1将必须构造一个新的分组,以把其HoA通知移动节点1000-1 (如具有ARA-Req信号的进入分组的源地址字段中指定的)。 First, the mobile access router 1200-1 will have to construct a new packet to the mobile node notifies its HoA 1000-1 (such as having a source address field of incoming packets ARA-Req signal specified). 以下把这一分组称为"访问路由器地址答复(A ccess-Router-Address-Response),,信号,或縮写为"ARA-Res,,。 Following the grouping known as the "access router address reply (A ccess-Router-Address-Response) ,, signal, or abbreviated as" ARA-Res ,,. 其次,移动访问路由器1200-1将必须去除或重新标记具有ARA-Req信号的进入分组,以便后继的上游路由器将不对ARA-Req进行答复。 Secondly, the mobile access router 1200-1 will have to be removed or re-mark the incoming packet has ARA-Req signal so that subsequent upstream router will not reply ARA-Req. 在这一方式下,下述情况是可能的,仅检测到分组中的ARA-Req信号的第一移动访问路由器1200-1将把ARA-Res发送于移动节点1000-1。 In this mode, the following cases are possible, only the detected packet ARA-Req signal in the first mobile access router 1200-1 will ARA-Res to the mobile node 1000-1 transmits. 下述情况也是可能的,当移动访问路由器1200-1上游转发具有ARA-Req信号的进入分组时,如果另一个移动访问路由器1200-1驻留在进一步的上游处,则这一上游移动访问路由器1200-1也将把ARA-Res发送于移动节点1000-1。 The following situation is also possible, when the mobile access router 1200-1 upstream forwards with ARA-Req signal into the packet, if another mobile access router 1200-1 resides at the further upstream, this upstream mobile access router is ARA-Res 1200-1 will also be sent to the mobile node 1000-1.

[0065] 移动访问路由器1200-1发送于移动节点1000-1的ARA-Res分组将需要载有下列信息:(1)关于本分组是对ARA-Req的答复的指示,以及(2)指定移动访问路由器1200-1的HoA的值。 [0065] mobile access router 1200-1 sends to the mobile node 1000-1 ARA-Res packet will need to contain the following information: (1) with respect to this group is to ARA-Req answer indication, and (2) specify the move access the router's HoA values 1200-1. 可选地,ARA-Res分组也可以载有原始分组(具有ARA-Req的分组)的一部分, 以便移动节点1000-1可以验证这是有效的答复。 Alternatively, ARA-Res packet can also be contained in the original packet (packet with the ARA-Req) part, so that the mobile node 1000-1 can verify that this is a valid answer.

[0066] 为了去除ARA-Req,确切的方法取决于ARA-Req是如何实现的。 [0066] To remove the ARA-Req, the exact method depends on how the ARA-Req is implemented. 如果ARA-Req为分组头标中的比特,则移动访问路由器1200-1可以简单地清除该比特以去除ARA-Req。 If the ARA-Req is a bit in the packet header, the mobile access router 1200-1 can simply clear the bit to remove the ARA-Req. 如果把ARA-Req作为路由器警告选项中的值加以实现,则移动访问路由器1200-1可以简单地丢弃路由器警告选项以去除ARA-Req,或把该值改变成某一其它值,以便后继的路由器将简单地忽视路由器警告选项。 If the ARA-Req as a router warning option value to be realized, the mobile access router 1200-1 can simply discard the router alert option to remove the ARA-Req, or to change the value to some other value, so that subsequent routers will simply ignore the router alert option.

[0067] 当接收到含有移动访问路由器1200-1的HoA的ARA-Res分组时,则移动节点1000-1然后可以前进来向其家乡代理1400-1和/或对方节点1500-1发送具有含有移动访问路由器1200-1的HoA的访问路由器选项的新BU消息。 [0067] When receiving the HoA mobile access router 1200-1 contains the ARA-Res packet, the mobile node 1000-1 can then move forward to its home agent or the other nodes send 1400-1 and 1500-1 / have contained New BU message mobile access router's HoA 1200-1 access router options. 此时,移动节点1000-1不应该插入ARA-Req,而应该遵循AR0方案所规定的行为。 In this case, the mobile node 1000-1 should not insert the ARA-Req, and it should follow the behavior specified AR0 program.

[0068] 概括地讲,当发出BU消息时,移动节点1000-1将遵循图2中所描述的算法。 [0068] Generally speaking, when you issue the BU message, the mobile node 1000-1 will follow two graph algorithms described. 在步骤S11000中,移动节点1000-1检查其是否知道其访问路由器的HoA。 In step S11000, the mobile node 1000-1 checks if it knows its access router's HoA. 如果其知道(或者通过从路由器广告消息中抽取的ARA-Info,或通过先前所接收的ARA-Res消息),则移动节点1000-1将把值等于访问路由器的HoA的访问路由器选项插入BU,如步骤S11100中所示。 If it is known (or by extracting from the router advertisement message in the ARA-Info, or through the ARA-Res message was previously received), the mobile node 1000-1 will a value equal to the HoA of the access router access router option inserted BU, As shown in step S11100. 如果其不知道,则移动节点1000-1把ARA-Req信号插入BU消息的分组头标中,如步骤S11200 中所示。 If it is not known, the mobile node 1000-1 of the ARA-Req signal is inserted BU message packet header, as shown in step S11200.

[0069] 对于移动访问路由器1200-1,本发明要求对其处理来自其入口的进入分组的方式略加修改。 [0069] For the mobile access router 1200-1, the present invention requires from its inlet to its handling of incoming packets slightly modified. 图3中说明了这一修改。 Figure 3 illustrates this modification. 首先,在步骤S12000中,移动访问路由器1200-1检查分组中是否存在ARA-Req信号。 First, in step S12000 in, ARA-Req signal whether the mobile access router 1200-1 checks the presence of the packet. 如果没有发现这样的信号,则移动访问路由器1200-1转向步骤S12300,其中其遵循正常的进入分组处理。 If you do not find such a signal, the mobile access router 1200-1 goes to step S12300, where it follows the normal incoming packet processing. 如果分组包含ARA-Req,则其将在转向步骤S12300之前,转向步骤12100和步骤S12200。 If the packet contains ARA-Req, it will in turn before step S12300, go to step 12100 and step S12200. 在步骤12100中,移动访问路由器1200-1把一个包含其HoA的ARA-Res分组发送到进入分组中所指定的源地址。 ARA-Res In step 12100, the mobile access router 1200-1 put a packet containing its HoA into the packet is sent to the specified source address. 在步骤S12200中,其从进入分组中去除ARA-Req消息,并且在步骤S12300中,其执行正常的进入分组的处理。 In step S12200, the removed ARA-Req message from the incoming packet, and in step S12300, which performs normal packet processing enters. [0070] 注意,当存储移动访问路由器1200-1的HoA时,移动节点1000-1应该把这一HoA 与其当前默认路由器(即局部固定路由器1100-1)的信息一起加以存储。 [0070] Note that when the memory of the mobile access router 1200-1 HoA, the mobile node 1000-1 should put this HoA its current default router (ie the local fixed router 1100-1) of information to be stored together. 这样做以便当移动节点1000-1移至一个新的位置时,其默认路由器的变化将导致其也清除所存储的移动访问路由器1200-1的HoA。 This is done so when the mobile node 1000-1 moves to a new position, change its default router will cause it also clears the stored mobile access router's HoA 1200-1.

[0071] 因此,使用本发明的第一实施例,甚至是在移动节点和移动访问路由器之间存在其它路由器的情况下,移动节点也具有获知上游移动访问路由器的HoA的机制。 When [0071] Accordingly, a first embodiment of the present invention is used, even the existence of other routers in between the mobile node and the mobile access router, the mobile node also has a mechanism to know the HoA of an upstream mobile access router's. 这允许移动节点把访问路由器选项嵌入绑定更新消息,从而允许ARO方案正常运作。 This allows the mobile node to access the router option embedded in the binding update message, allowing normal operation ARO program. [0072]〈第二实施例> [0072] <Second Embodiment>

[0073] 本发明的第二实施例描述了这样一种情况:移动访问路由器1200-1彻底扫描所有通过其一或多个入口的进入分组,以寻找移动节点1000-1所发送的绑定更新消息。 [0073] The second embodiment of the present invention describes a situation: the mobile access router 1200-1 completely scans all incoming packet through one or more inlets, in order to search for the mobile node 1000-1 binding update transmitted message. 由于移动节点1000-1正在使用ARO方案,所以在绑定更新消息中设置了特定比特。 Because the mobile node 1000-1 is using the ARO solution so set a particular bit in the binding update message. 移动访问路由器1200-1将知道发送方支持ARO方案但不知道其访问路由器的HoA。 Mobile access router 1200-1 will know that the sender supports the ARO program but do not know its access router's HoA. 于是,移动访问路由器1200-1把其HoA告诉发送方。 Thus, the mobile access router 1200-1 to its HoA tell the sender.

[0074] 对于这一第二实施例,再次使用了图1中的部署模式。 [0074] For this second embodiment, again using Figure 1 deployment pattern. 当移动节点1000-1首次启动时,其从局部固定路由器1100-1接收路由器广告消息。 When you first start the mobile node 1000-1, 1100-1 receives its router advertisement message from the local fixed router. 移动节点1000-1然后根据路由器广告中所载有的前缀信息配置其自身的CoA。 According to some mobile node 1000-1 then configure the prefix information contained in its own router advertisement CoA. 接下来,移动节点1000-1需要通过向家乡代理1400-1和对方节点1500-1发送BU消息而将要被绑定到其HoA的新CoA通知它们。 Next, the mobile node 1000-1 needs to inform them of the home agent 1400-1 and 1500-1 the other node sends BU message to be bound to the HoA of its new CoA. 由于局部固定路由器1100-1所发送的路由器广告不含有任何ARA-Info,所以移动节点1000-1 在其发出的BU消息中不能包括任何访问路由器选项。 Because of the local fixed router 1100-1 sent router advertisements do not contain any ARA-Info, the mobile node 1000-1 can not include any access router option in the BU message it sent in.

[0075] 移动节点1000-1可以可选择地使用访问路由器选项中预先指定的值(例如全0 或l地址)以指示:尽管其正在使用ARO方案,但是其不知道(尚不知道)其访问路由器的HoA。 [0075] The mobile node 1000-1 can optionally use the value (for example, the address of all 0s or l) to indicate the access router option in the pre-specified: ARO program despite its being used, but it does not know (yet know) their access router's HoA. 有时这可能是不必要的,因为ARO方案可以要求移动节点1000-1在BU消息中设置特定比特以表示其正在使用ARO方案。 Sometimes this may be unnecessary, because the ARO scheme may require the mobile node 1000-1 to set a specific bit in the BU message to indicate that it is using the ARO solution. 据此,访问路由器选项的不存在足以指明移动节点1000-1不知道其访问路由器的HoA。 Accordingly, there is no option to access the router's enough to indicate the mobile node 1000-1 does not know its access router's HoA.

[0076] 局部固定路由器1100-1接收分组,在确认分组有效之后,接下来,把分组上游转发于移动访问路由器1200-1。 [0076] the local fixed router 1100-1 receives the packet, after confirmation packet is valid, the next, the packet forwarding upstream mobile access router 1200-1. 移动访问路由器1200-1将检查其一或多个入口中的进入分组关于是否这些分组中任一个是BU消息。 Mobile access router 1200-1 will check one or more of the entry into the grouping in any of these groups is whether a BU message. 当检测到BU消息时,除了进入分组的正常处理之外,移动访问路由器1200-1将需要进一步检查BU是否指示发送方正在使用ARO方案。 When detecting a BU message, in addition to normal processing packets entering outside the mobile access router 1200-1 will need to further check whether the indication is sent BU Founder using ARO solution. [0077] 移动访问路由器1200-1发送于移动节点1000-1的ARA-Res分组将需要载有下列信息:(1)关于本分组是通知移动访问路由器1200-1的HoA的消息的指示,以及(2)指定移动访问路由器1200-1的HoA的值。 [0077] mobile access router 1200-1 sends to the mobile node 1000-1 ARA-Res packet will need to contain the following information: (1) About This notification indicates that the packet is a mobile access router 1200-1 HoA of messages, as well as (2) specify the value of the mobile access router's HoA of 1200-1. 可选地,ARA-Res分组也可以载有原始分组的(具有BU消息的分组)的一部分,以便移动节点1000-1可以验证这是有效答复。 Alternatively, ARA-Res packet can also contain a portion of the original packet (packet with the BU message) so that the mobile node 1000-1 can verify that this is a valid answer. [0078] 当接收到含有移动访问路由器1200-1的HoA的ARA-Res分组时,则移动节点1000-1可以然后可以前进来向其家乡代理1400-1和/或对方节点1500-1发送具有含有移动访问路由器1200-1的HoA的访问路由器选项的新BU消息。 [0078] When receiving the HoA mobile access router 1200-1 contains the ARA-Res packet, the mobile node 1000-1 can then be sent forward to having its home agent 1400-1 and 1500-1 / or other nodes BU message containing new mobile access router's HoA 1200-1 access router options. 此时,移动节点1000-1应采取ARO方案所规定的行为。 In this case, the mobile node 1000-1 should take ARO acts specified in the program.

[0079] 概括地讲,当发出BU消息时,移动节点1000-1将采用图4中所描述的算法。 [0079] Generally speaking, when issuing the BU message, the mobile node 1000-1 will use the algorithm described in Figure 4. 在步骤S21000中,移动节点1000-1检查其是否知道其访问路由器的HoA。 In step S21000, the mobile node 1000-1 checks if it knows its access router's HoA. 如果其知道(或者通过从路由器广告消息抽取的ARA-Info,或者通过先前所接收的ARA-Res消息),则移动节点1000-1将把值等于访问路由器的HoA的访问路由器选项插入BU,如步骤S21100中所示。 If it is known (or through a router advertisement message from the extracted ARA-Info, or by ARA-Res message was previously received), the mobile node 1000-1 will a value equal to the HoA of the access router access router option inserted BU, e.g. As shown in step S21100. 如果其不知道,则移动节点1000-1将发送BU消息,以便任何检查该BU消息的节点均将认识到:移动节点1000-1正在使用ARO方案,但不知道其访问路由器的HoA,如步骤S 21200 所指示的。 If it does not know, the mobile node 1000-1 sends BU messages to any inspection of the BU message nodes will recognize: the mobile node 1000-1 is using ARO program, but do not know its access router's HoA, as described in Step 21200 S indicated in. 换句话说,在步骤S21200中,移动节点1000-1发送具有指示ARO方案的使用的信息,但不具有访问路由器选项的BU。 In other words, in step S21200, the mobile node 1000-1 transmits with the use of information indicating ARO program, but does not have access router BU option.

[0080] 对于移动访问路由器1200-1,本发明要求对其处理来自其入口的进入分组的方式略加修改。 [0080] For the mobile access router 1200-1, the present invention requires from its inlet to its handling of incoming packets slightly modified. 图5中说明了这一修改。 Figure 5 illustrates this modification. 首先,在步骤S22000中,移动访问路由器1200-1检查进入分组是否为BU消息。 First, in step S22000, the mobile access router 1200-1 checks if the incoming packet is a BU message. 如果其不是,则执行正常的分组处理,如在步骤S22300中所示。 If it is not, the normal packet processing is performed, as shown in step S22300. 如果进入分组是BU消息,则在步骤S22100中,移动访问路由器1200-1进一步检查BU消息是否指出发送方正试图使用ARO方案,但不知道其访问路由器的HoA。 If the incoming packet is a BU message, in step S22100, the mobile access router 1200-1 further checks whether the BU message states that are trying to use to send Founder ARO program, but do not know its access router's HoA. 这可以从缺少访问路由器选项以及具有指示对ARO方案的使用的比特,或者从包含特殊标记的地址(例如全0地址,或全1地址)的访问路由器选项推导出来。 This can come from a lack of access to the router options and have a bit indicating the use of the ARO scheme, or from the address (for example, all 0's address or the address of all 1s) contains special access router option labeled derivation.

[0081] 如果其不能够推导BU消息的发送方正试图使用ARO方案,但不知道其访问路由器的HoA,则移动访问路由器1200-1转向步骤S22300,在步骤S22300中,其遵循原始ARO方案中所规定的正常的进入分组处理。 [0081] If it is not possible to derive BU messages sent Founder ARO program tries to use, but do not know its access router's HoA, the mobile access router 1200-1 to step S22300, S22300, in step, which follows the original plan in the ARO entering a predetermined normal packet processing. 如果其能够推导BU消息的发送方正试图使用ARO方案, If it can be deduced BU messages sent Founder ARO program tries to use,

1但不知道其访问路由器的HoA,则移动访问路由器1200-1转向步骤S22200,在步骤S22200 中,在执行S22300中所示的正常的进入分组处理之前,其向进入分组中所指定的源地址发送包含其HoA的ARA-Res分组。 1 but do not know its access router's HoA, the mobile access router 1200-1 goes to step S22200, in step S22200, before executing the normal incoming packet processing S22300 shown, in which the incoming packet source address specified ARA-Res send packets containing its HoA.

[0082] 如在第一实施例中那样,当存储移动访问路由器1200-1的HoA时,移动节点1000-1应该将移动访问路由器1200-1的HoA随其当前默认路由器(即局部固定路由器1100-1)的信息一起加以存储。 [0082] As in the first embodiment, when the memory of the mobile access router HoA 1200-1, 1000-1 mobile node should be mobile access router's HoA 1200-1 with its current default router (ie the local fixed router 1100 -1) of the information to be stored together. 这样做以便当移动访问路由器1200-1移至一个新位置时, 其默认路由器的变化将导致其也清除所存储的移动访问路由器1200-1的HoA。 This is done so when the mobile access router 1200-1 moves to a new location, change the default router will cause it also clears the stored mobile access router 1200-1 the HoA. [0083] 因此,使用本发明的第二实施例,甚至是在移动节点和移动访问路由器之间存在其它路由器的情况下,移动节点也具有获知上游移动访问路由器的HoA的机制。 When [0083] Thus, using the second embodiment of the present invention, even the existence of other routers in between the mobile node and the mobile access router, the mobile node also has a mechanism to know the HoA of an upstream mobile access router's. 这允许移动节点把访问路由器选项嵌入绑定更新消息,从而允许AR0方案正常运作。 This allows the mobile node to access the router option embedded in the binding update message, allowing normal operation AR0 program. [0084]〈第三实施例> [0084] <Third embodiment>

[0085] 本发明的第三实施例描述了这样一种情况:移动节点向其上游中的所有路由器发送特殊分组。 The third embodiment of the [0085] The present invention describes a situation: the mobile node sends a special packet to all its upstream router. 当接收到这一分组时,支持ARO方案的路由器将回复以它们的家乡地址。 When receiving the packet, the router supports the ARO program will return to their home address. [0086] 对于这一第三实施例,再次使用了图1中的部署模式。 [0086] For this third embodiment, again using Figure 1 deployment pattern. 当移动节点1000-1首次启动时,其从局部固定路由器1100-1接收路由器广告消息。 When you first start the mobile node 1000-1, 1100-1 receives its router advertisement message from the local fixed router. 移动节点1000-1然后根据路由器广告中所载有的前缀信息配置其自身的CoA。 According to some mobile node 1000-1 then configure the prefix information contained in its own router advertisement CoA. 接下来,移动节点1000-1需要通过向家乡代理1400-1和对方节点1500-1发送BU消息而将要被绑定到其HoA的新CoA通知它们。 Next, the mobile node 1000-1 needs to inform them of the home agent 1400-1 and 1500-1 the other node sends BU message to be bound to the HoA of its new CoA. 由于局部固定路由器1100-1所发送的路由器广告不含有任何ARA-Info,所以移动节点1000-1 在其发出的BU消息中不能包括任何访问路由器选项。 Because of the local fixed router 1100-1 sent router advertisements do not contain any ARA-Info, the mobile node 1000-1 can not include any access router option in the BU message it sent in.

[0087] 当发生这种情况时,移动节点1000-1延迟BU消息的发送,取而代之,向所有上游路由器发送出特殊分组以请求知道它们的HoA。 [0087] When this happens, the mobile node 1000-1 BU delay sending the message, instead, send a special packet to all upstream routers to request to know their HoA. 这一特殊分组可以呈因特网控制消息协议(ICMP)的形式,其中一特定类型指示其是访问路由器的地址请求。 This particular packet may be in the Internet Control Message Protocol (ICMP) form, which indicates that it is a particular type requests access router address. 或者,其也可以为正常的路由器恳求消息(参见非专利文献10),其中一特殊选项指示接收方应该把它们的家乡地址包含在路由器广告答复中。 Alternatively, it may be a normal router Solicitation message (see Non-Patent Document 10), wherein a particular option indicates that they should be the recipient's home address is included in the router advertisement reply. 为了便于解释,我们把这一分组称为访问路由器地址探测(AccessRouter Address Probe)消息,或简称为ARA-Probe。 For ease of explanation, we address this grouping is called an access router detection (AccessRouter Address Probe) message, or simply ARA-Probe.

[0088] 由于移动节点1000-1不知道上游移动访问路由器1200-1的存在,所以它将必须在ARA-Probe的目的地字段中使用广播或多播(multicast)地址。 [0088] As the mobile node 1000-1 does not know the upstream mobile access router 1200-1 existence, so it must be used in the destination field ARA-Probe's broadcast or multicast (multicast) address. IPv6定义了一种涉及所有路由器的"所有路由器多播地址"。 IPv6 defines a process involving all routers "all routers multicast address." 移动节点1000-1可以把该地址用作目的地地址。 The mobile node 1000-1 can take the address as the destination address. 或者,也可以定义一种特殊的多播地址,以致其仅涉及上游路由器。 Alternatively, you can define a special multicast addresses that it relates only to the upstream router. 以下,把这一多播地址称为上游路由器多播地址。 Hereinafter, the multicast address is called the upstream router multicast address. 这意味着所有路由器将默然忽视从它们的出口所接收的寻址到上游路由器多播地址的任何分组,并且将把从入口所接收的寻址到上游路由器多播地址的分组转发到出口。 This means that all routers will silence ignore any packets received from the outlet thereof is addressed to the multicast address of the upstream router, and from the inlet will received addressed to the upstream multicast router forwards the packet address to the outlet.

[0089] 为了限制多播地址的泛流(flooding)量,IPv6具有跳限制字段,用于限制可转发一个分组的次数。 [0089] In order to limit the flow of multicast addresses pan (flooding) amount, IPv6 has a hop limit field, you can forward a packet is used to limit the number of times. 移动节点1000-l可以使用小的跳限制值(例如2或3)以减小泛流。 1000-l mobile node can use a small hop limit value (e.g. 2 or 3) to reduce the flooded. [0090] 局部固定路由器1100-1将接收ARA-Probe。 [0090] the local fixed router 1100-1 will receive the ARA-Probe. 其将很可能不理解这一分组,但将继续向上游转发这一分组(即转发到移动访问路由器1200-1)。 It will probably not understand this grouping, but will continue to forward the packet to the upstream (ie, forwarded to the mobile access router 1200-1). 一旦移动访问路由器1200-1 接收到这一分组,它将把ARA-Res发送于这一ARA-Probe的发送方(即移动节点1000-1), 如本发明的第一实施例中所描述的。 Once the mobile access router 1200-1 receives this packet, it will send the ARA-Res to the sender of this ARA-Probe (i.e. the mobile node 1000-1), as in the first embodiment of the present invention described .

[0091] 移动访问路由器1200-1向移动节点1000-1发送的ARA-Res分组将需要载有下列信息:(1)关于本分组是对ARA-Pfobe的答复的指示,以及(2)指示移动访问路由器1200-1 的HoA的值。 [0091] mobile access router 1200-1 to 1000-1 ARA-Res packet sent from the mobile node will contain the following information is required: (1) with respect to this group is to ARA-Pfobe answer indication, and (2) indicates that the mobile access the router's HoA values 1200-1. 可选地,ARA-Res分组也可以载有原始分组的(具有BU消息的分组)的一部分,以便移动节点1000-1可以验证这是有效答复。 Alternatively, ARA-Res packet can also contain a portion of the original packet (packet with the BU message) so that the mobile node 1000-1 can verify that this is a valid answer. 由于移动访问路由器1200-1已经答复以ARA-Res,所以如果移动访问路由器1200-1不应继续向上游转发ARA-Probe,则其可以前进来丢弃具有ARA-Probe的分组,或者删除ARA-Probe消息或使ARA-Probe消息无效,然后执行与针对正常分组的处理相同的处理。 As the mobile access router 1200-1 had replied to ARA-Res, so if the mobile access router 1200-1 should not continue to be forwarded to the upstream ARA-Probe, then it can go forward to discard packets with ARA-Probe, or delete the ARA-Probe or ARA-Probe message so that the message is invalid, and perform the same process for the normal packet processing.

[0092] 在移动节点1000-1已接收到ARA-Res之后,其可以发出其填写了访问路由器选项的BU消息。 [0092] After the mobile node 1000-1 has received the ARA-Res, which can fill the BU message issued its access router options. 移动节点1000-1和移动访问路由器1200-1的其余的操作将遵循原始ARO方案中规定的操作。 The rest of the mobile node operation and mobile access router 1200-1 1000-1 will follow the operation specified in the original ARO program. 注意,移动节点1000-1使用广播方法接收一个以上的ARA-Res是可能的。 Note that, the mobile node 1000-1 using the broadcast method of receiving more than one ARA-Res is possible. 在这一情况下,移动节点1000-1应该使用其最初接收的ARA-Res,因为答复回来最快的答复方被视为最近的。 In this case, the mobile node 1000-1 should use its first received ARA-Res, as replies come back fastest is considered recent respondents.

[0093] 概括言之,当发出BU消息时,移动节点1000-1将采用图6中所描述的算法。 [0093] summarized words, when issuing the BU message, the mobile node 1000-1 will use the algorithm described in Figure 6. 在步骤S31000中,移动节点1000-1检查其是否知道其访问路由器的HoA。 In step S31000, the mobile node 1000-1 checks if it knows its access router's HoA. 如果移动节点1000-1知道这一HoA(或者通过从路由器广告消息抽取的ARA-Info,或者通过先前所接收的ARA-Res消息),则移动节点1000-1将把值等于访问路由器的HoA的访问路由器选项插入BU,如步骤S31100中所示。 If the mobile node 1000-1 knows the HoA (or through a router advertisement message from the extracted ARA-Info, or by ARA-Res message was previously received), the mobile node 1000-1 will a value equal to the HoA of the access router access router option insert BU, as shown in step S31100. 如果移动节点1000-1不知道这一HoA,则移动节点1000-1 将转向步骤S31200,在步骤S31200中,其发出ARA-Probe。 If the mobile node 1000-1 does not know the HoA, the mobile node 1000-1 will go to step S31200, in step S31200, which issued ARA-Probe. 然后移动节点1000-1进入等待状态,如步骤S31300中所示,在步骤S31300中,其等待接收有效的ARA-Res,或者等待超时(timeout)。 The mobile node 1000-1 then enters a wait state, as shown in step S31300, step S31300, which waits to receive a valid ARA-Res, or wait for a timeout (timeout). 当接收到有效的ARA-Res时,移动节点1000-1将转向步骤S31100,在步骤31100中,其发送插入了访问路由器选项的BU,其中,把访问路由器的HoA的值设置为等于从ARA-Res所抽取的HoA的值。 Upon receiving a valid ARA-Res, the mobile node 1000-1 will go to step S31100, in step 31100, the BU sends the access router option inserted, wherein the HoA of the access router is set equal to the value from ARA- value of HoA extracted Res. 当其为超时时,移动节点1000-1假设其上游中不存在移动访问路由器1200-1,并且前进来发送不具任何访问路由器选项的BU,如步骤S31400中所示。 When it is time-out, it is assumed that the mobile node 1000-1 does not exist upstream mobile access router 1200-1, and proceeds to send the access router does not have any options BU, as shown in step S31400.

[0094] 对于移动访问路由器1200-1,本发明要求对其处理来自其入口的进入分组的方式略加修改。 [0094] For the mobile access router 1200-1, the present invention requires from its inlet to its handling of incoming packets slightly modified. 图7中说明了这一修改。 Figure 7 illustrates this modification. 首先,在步骤S32000中,移动访问路由器1200-1检查进入分组是否为ARA-Probe。 First, in step S32000, the mobile access router 1200-1 checks if the incoming packet is ARA-Probe. 如果分组不是ARA-Probe,则移动访问路由器1200-1转向步骤S32100,在步骤S32100中,其遵循正常的进入分组处理。 If the packet is not the ARA-Probe, the mobile access router 1200-1 to step S32100, S32100, in step, which follows the normal incoming packet processing. 如果分组是ARA-Probe,则移动访问路由器1200-1将转向步骤S32200,在步骤S32200中,其向进入分组中所指定的源地址发送包含其HoA的ARA-Res分组。 If the packet is ARA-Probe, the mobile access router 1200-1 will turn to step S32200, in step S32200, which to enter the specified source packet containing its HoA address to send the ARA-Res packet.

[0095] 如在以上所提到的第一实施例中那样,当存储移动访问路由器1200-1的HoA时, 移动节点1000-1应该将移动访问路由器1200-1的HoA随其当前默认路由器(即局部固定路由器1100-1)的信息一起加以存储。 [0095] As in the first embodiment, as mentioned above, when the memory of the mobile access router HoA 1200-1, 1000-1 mobile node should be mobile access router's HoA 1200-1 with its current default router ( That local fixed router 1100-1) information to be stored together. 这样做以便当移动节点1000-1移至一个新位置时, 其默认路由器的变化将导致其也清除所存储的移动访问路由器1200-1的HoA。 This is done so when the mobile node 1000-1 moves to a new location, change the default router will cause it also clears the stored mobile access router's HoA 1200-1. [0096] 如以上所提到的,使用本发明的第三实施例,甚至是在移动节点和移动访问路由器之间存在其它路由器的情况下,移动节点也具有获知上游移动访问路由器的HoA的机制。 When [0096] As noted above, the use of a third embodiment of the present invention, even in the presence of other routers between the mobile node and the mobile access router, the mobile node also has a mechanism to know the HoA of an upstream mobile access router of . 这允许移动节点把访问路由器选项嵌入绑定更新消息,从而允许ARO方案正常运作。 This allows the mobile node to access the router option embedded in the binding update message, allowing normal operation ARO program. [0097]〈第四实施例〉 [0097] <Fourth Embodiment>

[0098] 本发明的第四实施例描述了这样一种情况:局部固定路由器被配置以便其将能够把其所连接到的移动访问路由器的主全局地址嵌入到局部固定路由器本身发送的路由器广告消息中。 [0098] The fourth embodiment of the present invention describes a situation: local fixed router is configured so that it will be able to connect it to the primary global address of the mobile access router to the router advertisement message embedded local fixed router itself sends the in.

[0099] 对于第四实施例,再次使用了图1中的部署模式。 [0099] For the fourth embodiment, again using Figure 1 deployment pattern. 此处,局部固定路由器1100-1被配置来针对其默认路由器(即移动访问路由器1200-1)所发送的路由器广告监听其出口。 Here, the local fixed router 1100-1 is configured to (ie mobile access router 1200-1) router advertisements sent by listeners of its exports against its default router. [0100] —旦检测到路由器广告包含ARA-Info,局部固定路由器1100-1将存储从ARA-Info所抽取的地址。 [0100] - Once detected, the router advertisement contains the ARA-Info, the local fixed router 1100-1 will be stored from ARA-Info extracted address. 接下来,当局部固定路由器1100-1把其自己的路由器广告发出至其一或多个入口时,其将把包含其默认路由器的这一HoA的ARA-Info插入路由器广告中。 ARA-Info Then, when the local fixed router 1100-1 to issue its own router advertisement when one or more of the entrance to, it will contain the default router for this HoA insert router advertisements. 因此,对于移动节点IOOO-I,将看起来仿佛局部固定路由器1100-1是支持ARO方案的移动访问路由器;而实际上,局部固定路由器1100-1不需要了解ARO方案的主要部分。 Therefore, the mobile node IOOO-I, will look as if the local fixed router 1100-1 ARO program supports mobile access router; in fact, the local fixed router 1100-1 need to know the main part of the ARO program. 取而代之,其只需要知道如何从它已从移动访问路由器1200-1那里接收的路由器广告中抽取移动访问路由器1200-1的HoA,然后把移动访问路由器1200-1的HoA插入局部固定路由器1100-1自身发送的路由器广告中。 Instead, it only needs to know how to extract the HoA of the mobile access router 1200-1 from its mobile access router 1200-1 from there received router advertisement, then the mobile access router HoA 1200-1 inserting local fixed router 1100-1 their router advertisements sent.

[0101] 当存储移动访问路由器1200-1的HoA时,局部固定路由器1100-1应该把这一HoA 随其当前的默认路由器(即移动访问路由器1200-1)的信息一起加以存储。 Information [0101] When the storage HoA 1200-1 mobile access router, the local fixed router 1100-1 should put this HoA with its current default router (ie the mobile access router 1200-1) is stored together. 这样做以便当移动节点1000-1移至一个新位置时,其默认路由器的变化将导致其也清除所存储的移动访问路由器1200-1的HoA。 This is done so when the mobile node 1000-1 moves to a new location, change the default router will cause it also clears the stored mobile access router's HoA 1200-1.

[0102] 因此,在本发明的第四实施例中,对于原始ARO方案的唯一修改是局部固定路由器1100-1。 [0102] Thus, in the fourth embodiment of the present invention, the only modification to the original ARO solution is the local fixed router 1100-1. 移动节点1000-1和移动访问路由器1200-1均遵循原始ARO方案中所规定的过程。 Mobile node 1000-1 and the mobile access router 1200-1 follow a procedure as specified in the original program of ARO. 图8描述了对来自局部固定路由器1100-1的出口的进入分组的正常处理的修改。 Figure 8 illustrates a modification to the normal processing of incoming packets from the local fixed router 1100-1 outlet's. 在步骤S41000中,局部固定路由器1100-1首先检查来自出口的进入分组是否为路由器广告。 In step S41000, the local fixed router 1100-1 first checks whether incoming packets from the export of the router advertisements. 如果进入分组不是路由器广告,则执行步骤S41100,在步骤S41100中,将执行分组的正常处理(针对所有一般IP路由器的可能处理)。 If the incoming packet is not a router advertisement, step S41100, S41100, in step, the normal processing is executed (possible treatment for all general IP router) packets. 如果进入分组是路由器广告,则将执行对路由器广告的正常处理,如步骤S41200中所示。 If the incoming packet is a router advertisement, the router advertisement will be performed on the normal processing, as shown in step S41200. 这一过程可以导致局部固定路由器1100-1 改变其所配置的默认路由器。 This process can lead to local fixed router 1100-1 change their default router configuration.

[0103] 在这一处理(步骤S41200的处理)之后,检查路由器广告,以查看其是否来自局部固定路由器1100-1的默认路由器,如步骤S41300中所示。 [0103] After this processing (the processing in step S41200), the router advertisement check to see if the default router from the local fixed router 1100-1, as shown in step S41300. 如果其不是来自默认路由器, 则不要求进一步的处理。 If it is not from the default router, further processing is not required. 如果其来自默认路由器,则接下来在步骤S41400中检查路由器广告,查看其是否包含ARA-Info。 If it comes from a default router, check the router advertisement in the next step S41400, and see if it contains the ARA-Info. 如果路由器广告不包含ARA-Info,则清除存储默认路由器的HoA的内部变量。 If the router does not contain advertising ARA-Info, clears the stored HoA of the default router internal variables. 如果路由器广告包含ARA-Info (默认路由器的HoA),则在步骤S41600 中把这一地址存储在以上提到的内部变量中。 If the router advertisement contains the ARA-Info (the default router HoA), then in step S41600 in the address stored in the internal variable in the above mentioned.

[0104] 以下所描述的对局部固定路由器1100-1行为的修改,是在把路由器广告发出至其入口时进行的。 [0104] on the local fixed router 1100-1 behavior modification described below, is in the router advertisement issued to its entrance conducted. 图9描述了这一修改。 Figure 9 illustrates this change. 在步骤S42000中,局部固定路由器1100-1首先检查其是否拥有(知道)其默认路由器(即移动访问路由器1200-1)的先前所存储的HoA。 In step S42000, the local fixed router 1100-1 first check if it has (knows) its default router (i.e. the mobile access router 1200-1) the previously stored HoA. 如果不具有这一HoA,则将执行步骤S42100,在步骤S42100中,局部固定路由器1100-1将发出不具ARA-Info的路由器广告。 If you do not have the HoA, then step S42100, in step S42100, the local fixed router 1100-1 will issue a non-ARA-Info router advertisements. 另一方面,如果其拥有其默认路由器的先前所存储的HoA,则局部固定路由器1100-1将把ARA-Info插入包含默认路由器的HoA的路由器广告中,如步骤S42200中所示。 On the other hand, if it has its default router of the previously stored HoA, the local fixed router 1100-1 will insert an ARA-Info HoA of the default router in the router advertisement, as shown in step S42200.

[0105] 如以上所述,使用本发明的第四实施例,甚至是在移动节点和移动访问路由器之间存在其它路由器的情况下,移动节点也具有获知上游移动访问路由器的HoA的机制。 When [0105] As described above, the use of a fourth embodiment of the present invention, even the existence of other routers in between the mobile node and the mobile access router, the mobile node also has informed the upstream mobile access router's HoA mechanism. 这允许移动节点把访问路由器选项嵌入绑定更新消息,从而允许ARO方案正常运作。 This allows the mobile node to access the router option embedded in the binding update message, allowing normal operation ARO program. [0106] 产业上的可应用性 [0106] Industrial Applicability

[0107] 本发明能够甚至是在局部固定路由器驻留在形成移动网络的移动访问路由器和连接于这一移动网络的移动节点之间的情况下也向移动节点和移动网络提供全局连接性。 [0107] The present invention can even reside in the local fixed router in case of mobile access routers between the mobile network and the mobile node is connected to the mobile network also provides global connectivity to mobile nodes and mobile networks. 因此,本发明可适用于提供全局连接性的通信网络技术,特别是使用IP的通信技术。 Accordingly, the present invention is applicable to provide global connectivity of a communication network technology, in particular the use of IP-based communications technology.
