The terms "network" and "system" can be replaced with each other. A CDMA network may implement wireless technologies such as universal terrestrial radio access (UTRA), CDMA2000, and the like. UTRA can include variants of CDMA (WCDMA) and other CDMA. CDMA2000 can cover the Interim Standard (IS) 2000 (IS-2000), IS-95 and IS-856 standards. The TDMA network can implement a wireless technology such as a global system for mobile communication (GSM). An OFDMA network may implement such as evolved universal radio terrestrial access (evolved UTRA, E-UTRA), ultra mobile broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash OFDMA And other wireless technologies.

The technology described in the embodiments of the present invention can also be applied to the wireless network and the wireless technology described above.
本发明实施例提供的通信网络可以包括:接入网设备、网关设备和控制服务器等。所述接入网设备、网关设备和控制服务器在不同的通信系统中可以有不同的名称和结构,不过实现的功能相同。例如,在LTE系统中,所述接入网设备可以为演进型节点B(evolved NodeB,eNodeB),也可以为家庭型eNodeB(HeNB,home eNodeB)等小基站。在UMTS系统中,所述接入网设备可以包括节点B(Node B)和无线网络控制器(RNC,Radio Network Controller)。网关设备可以包括服务网关(S-GW,serving gateway)和公用数据网关(P-GW,public data network Gateway),它们可以分开独 立部署,亦可以合一部署。控制服务器可以是PCRF实体,在线计费系统(OCS,online charging system)或验证、授权、记账(AAA,authentication,authorization,accounting)服务器等。The communication network provided by the embodiment of the present invention may include: an access network device, a gateway device, a control server, and the like. The access network device, the gateway device, and the control server may have different names and structures in different communication systems, but the functions implemented are the same. For example, in an LTE system, the access network device may be an evolved NodeB (eNodeB) or a small base station such as a home eNodeB (HeNB). In the UMTS system, the access network device may include a Node B and a Radio Network Controller (RNC). The gateway device may include a service gateway (S-GW) and a public data network (P-GW), which may be separately Deployment can also be deployed in one. The control server may be a PCRF entity, an online charging system (OCS), or an authentication, authorization, accounting (AAA, authentication, authorization, accounting) server.
所述控制服务器在UE接入网络的过程中,和网关设备进行交互,可以对UE的接入网络的过程进行控制,当控制服务器出现故障时,将无法对用户设备的进行接入控制;当控制服务器出现过载时,也可能无法对用户设备进行接入控制。以上都会导致用户设备接入网络失败。此时,用户设备会自动反复尝试接入网络,信令流量持续累加,从而形成网络信令风暴,导致网络拥塞。网络中各个设备抵抗这种“风暴”的能力很差,一旦发生信令风暴,可能会造成网络性能急剧恶化,进而导致整个网络瘫痪。The control server interacts with the gateway device during the process of the UE accessing the network, and can control the process of accessing the network of the UE. When the control server fails, access control of the user equipment cannot be performed; When the control server is overloaded, access control of the user equipment may not be possible. The above will cause the user equipment to fail to access the network. At this time, the user equipment automatically attempts to access the network repeatedly, and the signaling traffic continues to accumulate, thereby forming a network signaling storm, resulting in network congestion. The ability of each device in the network to resist this "storm" is very poor. Once a signaling storm occurs, the performance of the network may deteriorate drastically, which may cause the entire network to collapse.

Access to the network effectively solves the resulting network signaling storm, thereby alleviating network congestion.
用户设备可以通过向接入网设备发送附着请求(attach request)消息请求接入网络,所述接入请求信息可以承载在附着请求消息中。The user equipment may request to access the network by sending an attach request message to the access network device, and the access request information may be carried in the attach request message.
接入网设备可以将所述接入请求信息通过发送消息的方式传递给所述网关设备,接入网设备可以通过移动性管理设备将所述接入请求信息发送给所述网关设备。所述网关设备可以通过接收所述接入网设备发送的创建会话请求(create session request)消息获取所述接入请求信息,所述创建会话请求消息中包含所述接入请求信息。The access network device may transmit the access request information to the gateway device by sending a message, and the access network device may send the access request information to the gateway device by using a mobility management device. The gateway device may obtain the access request information by receiving a create session request message sent by the access network device, where the create session request message includes the access request information.
网关设备将根据所述接入请求信息控制服务器对所述用户设备进行接入控制,譬如,在网关设备将根据所述接入请求信息为所述用户设备建立传输承载的该过程中,网关设备请求控制服务器对所述用户设备进行接入控制。可选地,所述接入控制为请求与所述控制服务器建立会话。建立会话的过程可以为在所述控制服务器中保存用户设备的注册信息、向所述网关设备返回用户设备的历史签约信息、向所述网关设备返回对用户设备应用的各种策略控制规则信息或者向所述网关设备返回用户设备的数据网络访问权限等等中的至少一种。The gateway device controls the server to perform access control on the user equipment according to the access request information, for example, in the process that the gateway device establishes a transport bearer for the user equipment according to the access request information, the gateway device The request control server performs access control on the user equipment. Optionally, the access control is to request to establish a session with the control server. The process of establishing a session may be: storing registration information of the user equipment in the control server, returning historical subscription information of the user equipment to the gateway device, and returning, to the gateway device, various policy control rule information applied to the user equipment or Returning to the gateway device at least one of data network access rights of the user equipment, and the like.
所述网关设备根据所述接入请求信息请求控制服务器对所述用户设备进行接入控制可以是向所述控制服务器发送会话建立请求信息。前述已经说明所述控制服务器可以是PCRF实体、OCS或者AAA服务器。基于此,所述会话 建立请求信息可以承载在所述网关设备向OCS或者PCRF实体发送的初始信用控制请求(CCR-Initial,credit control request-Initial)消息中;也可以承载在所述网关设备向AAA服务器发送的鉴权请求(authentication request)消息或者记帐开始请求(accounting start request)消息中。And the gateway device requesting the control server to perform access control on the user equipment according to the access request information may be sending session establishment request information to the control server. The foregoing has explained that the control server can be a PCRF entity, an OCS or an AAA server. Based on this, the conversation The establishment request information may be carried in an initial credit control request (CCR-initial, credit control request-initial) message sent by the gateway device to the OCS or PCRF entity; or may be carried in the authentication sent by the gateway device to the AAA server. An authentication request message or an accounting start request message.
可选地,当所述控制服务器发生故障或者过载时,所述控制服务器对所述用户设备进行的接入控制失败。Optionally, when the control server fails or is overloaded, the access control performed by the control server on the user equipment fails.
在本发明实施例中,当所述控制服务器发生过载时,网关设备可以确定所述控制服务器对所述用户设备进行的接入控制失败。例如,所述网关设备接收到所述控制服务器为响应所述会话建立请求信息发送的会话建立响应信息,所述会话建立响应信息用于指示所述控制服务器过载并拒绝对所述用户设备进行接入控制,则可以确定所述控制服务器对所述用户设备进行的接入控制失败。例如,所述控制服务器为PCRF实体时,所述会话建立响应信息可以承载在PCRF实体向网关设备发送的信用控制应答(CCA,credit control answer)消息中。In the embodiment of the present invention, when the control server is overloaded, the gateway device may determine that the access control of the user equipment by the control server fails. For example, the gateway device receives the session establishment response information sent by the control server in response to the session establishment request information, where the session establishment response information is used to indicate that the control server is overloaded and refuses to connect to the user equipment. In the control, it may be determined that the access control of the user equipment by the control server fails. For example, when the control server is a PCRF entity, the session establishment response information may be carried in a credit control answer (CCA) message sent by the PCRF entity to the gateway device.
或者,当所述控制服务器发生故障时,网关设备可以确定所述控制服务器对所述用户设备进行的接入控制失败。例如,网关设备在发送所述会话建立请求信息后,经过预设时间未收到所述控制服务器对于所述会话建立请求信息的响应信息,可以确定所述控制服务器对所述用户设备进行的接入控制失败。Alternatively, when the control server fails, the gateway device may determine that the access control of the user equipment by the control server fails. For example, after the gateway device sends the session establishment request information, the control server does not receive the response information of the control server for the session establishment request information, and may determine, by the control server, the user equipment. Incoming control failed.
在本发明实施例中,当所述网关设备确定在当所述控制服务器发生过载时,或者所述控制服务器发生故障时,所述网关设备可以确定所述控制服务器对所述用户设备进行的接入控制失败。进一步,根据该所述控制服务器对所述用户设备进行的接入控制失败的确定结果,网关设备进一步确定所述用户设备 接入网络失败。In the embodiment of the present invention, when the gateway device determines that when the control server is overloaded, or the control server fails, the gateway device may determine that the control server performs the connection to the user equipment. Incoming control failed. Further, the gateway device further determines the user equipment according to the determination result that the control server fails to perform access control on the user equipment. Access to the network failed.
在本发明实施例中,所述接入响应信息可以包含在附着接受(attach accept)消息中。In the embodiment of the present invention, the access response information may be included in an attach accept message.
在现有技术中,所述控制服务器无法对所述用户设备进行接入控制并且最终导致用户设备接入网络失败时,网关设备向用户设备发送所述用户设备请求接入网络失败的接入响应信息。而本发明实施例提供的技术方案中,为了避免用户设备由于附着失败而反复通过发起附着流程尝试接入网络,造成网络拥塞,虽然用户设备接入网络失败,网关设备仍然通过接入网设备发送指示用户设备请求接入网络成功的接入响应信息到所述用户设备。此时用户设备并没有真正地接入网络,因此所述步骤S106可以称为对所述用户设备的假激活,或者称之为假接入。In the prior art, when the control server fails to perform access control on the user equipment and finally causes the user equipment to fail to access the network, the gateway device sends, to the user equipment, an access response that the user equipment requests to access the network. information. In the technical solution provided by the embodiment of the present invention, in order to prevent the user equipment from repeatedly attempting to access the network through the initiation of the attach procedure due to the attachment failure, the network is congested, and although the user equipment fails to access the network, the gateway device still sends the information through the access network device. Instructing the user equipment to request access to the network for successful access response information to the user equipment. At this time, the user equipment does not really access the network, so the step S106 may be referred to as a fake activation of the user equipment, or as a fake access.
在本发明实施例中,网关设备可以对假激活的用户设备进行标识,尤其是当网关设备接收到大量的用户设备的接入网络请求,其中部分用户设备真正地成功接入网络,而部分用户设备是根据上述方法实施例的方法,并不是真正接入网络时,所述网关设备可以对这些假激活的用户设备进行标识,例如,将所述用户设备保存在一张假激活用户列表当中。当网关设备获知所述控制服务器的故障解除或者过载消除时,可以优先触发这些标识的假激活用户设备重新发起接入网络请求,从而实现真正地接入网络。In the embodiment of the present invention, the gateway device may identify the user equipment that is falsely activated, especially when the gateway device receives a large number of access network requests of the user equipment, and some of the user equipments successfully access the network, and some users The device is a method according to the foregoing method embodiment. When the network device does not actually access the network, the gateway device may identify the fake activated user equipment, for example, save the user equipment in a fake active user list. When the gateway device learns that the control server is fault-cancelled or overloaded, the false-activated user equipment that triggers the identification may be preferentially triggered to re-initiate the access network request, thereby realizing access to the network.
因此,可选地,如图1所示,本发明实施例的方法还可以包括:Therefore, optionally, as shown in FIG. 1 , the method of the embodiment of the present invention may further include:

When the fault of the control server is removed or the overload is removed, the gateway device may actively recover the user who is falsely activated as a user who can normally access the network.
可选地,触发所述控制服务器对所述用户设备进行接入控制的方式可以是,所述网关设备通过所述接入网设备发送去激活承载请求信息到所述用户设备,所述去激活承载信息用于通知所述用户设备重新发送接入请求信息,以使得所述控制服务器对所述用户设备重新进行接入控制。所述接入网设备将该去激活承载信息包含在重配置消息中发送到所述用户设备,所述用户设备在得知后便会重新发起附着流程请求接入网络,之后所述控制服务器对所述用户设备重新发送的接入网络的请求进行接入控制。若所述控制服务器对所述用户设备接入控制成功,所述网关设备通过所述接入网设备向所述用户设备发送所述用户设备接入网络成功的信息。Optionally, the manner in which the control server is configured to perform access control on the user equipment may be: the gateway device sends, by using the access network device, deactivation of bearer request information to the user equipment, where the deactivation is performed. The bearer information is used to notify the user equipment to resend the access request information, so that the control server re-accesses the user equipment. The access network device sends the deactivated bearer information to the user equipment in the reconfiguration message, and the user equipment re-initiates the attach procedure to request the access network after the information is obtained, and then the control server pairs The request for accessing the network resent by the user equipment performs access control. And if the control server successfully performs access control on the user equipment, the gateway device sends, by using the access network device, information that the user equipment accesses the network successfully to the user equipment.
其中,去激活承载请求信息可以承载在删除承载请求(delete bearer request)消息中,重配置消息可以是无线资源控制连接重配置(RRC connection reconfiguration)消息。The deactivated bearer request information may be carried in a delete bearer request message, where the reconfiguration message may be an RRC connection reconfiguration message.
可选地,触发所述控制服务器对所述用户设备进行接入控制的实现方式还可以是,所述网关设备重新请求所述控制服务器对所述用户设备进行接入控 制。所述重新请求所述控制服务器对所述用户设备进行接入控制可以是重新向所述控制服务器发送会话建立请求信息。所述会话建立请求信息可以承载在所述网关设备向OCS或者PCRF实体发送的初始信用控制请求消息中;也可以承载在所述网关设备向AAA服务器发送鉴权请求消息中或者记账开始请求消息中。当所述设备为OCS或者PCRF实体时,所述会话建立请求信息还可以承载在更新信用控制请求(CCR-update,credit control request-update)消息中。若所述控制服务器对所述用户设备接入控制成功,所述网关设备通过所述接入网设备向所述用户设备发送所述用户设备接入网络成功的信息。Optionally, the method for triggering the control server to perform access control on the user equipment may be that the gateway device re-requests the control server to perform access control on the user equipment. system. The re-requesting the control server to perform access control on the user equipment may be to resend the session establishment request information to the control server. The session establishment request information may be carried in an initial credit control request message sent by the gateway device to an OCS or PCRF entity; or may be carried in the gateway device to send an authentication request message or a billing start request message to the AAA server. in. When the device is an OCS or PCRF entity, the session establishment request information may also be carried in a CCR-update (credit control request-update) message. And if the control server successfully performs access control on the user equipment, the gateway device sends, by using the access network device, information that the user equipment accesses the network successfully to the user equipment.
可选地,若所述网关设备确认所述控制服务器发生过载导致对所述用户设备进行的接入控制失败,且满足当所述网关设备检测到的所述用户设备发送的心跳报文的数据流量大于数据流量阈值或者所述网关设备检测到所述用户设备发送的数据内容属于预先设定的数据内容时,如图1所示,在S106后本发明实施例的方法还可包括:Optionally, if the gateway device confirms that the control server is overloaded, the access control of the user equipment fails, and the data of the heartbeat message sent by the user equipment that is detected by the gateway device is met. When the traffic is greater than the data traffic threshold or the gateway device detects that the data content sent by the user equipment belongs to the preset data content, as shown in FIG. 1 , the method of the embodiment of the present invention may further include:

当所述用户设备累计发送的心跳报文的数据流量达到一定数量级时,比如超过了预先设定的一个阈值时,说明所述用户设备需要发送数据的请求已经维持一段时间。当所述控制服务器处于过载的状态时,还是可以接收适当的业务需求的,此时,可以优先对所述用户设备进行接入控制,使得用户设备成功接入网络,进而使用户设备实现数据传输,因此网关设备可以主动重新请求所述控制服务器对所述用户设备进行接入控制。When the data traffic of the heartbeat message sent by the user equipment reaches a certain level, for example, when a predetermined threshold is exceeded, the request that the user equipment needs to send data has been maintained for a period of time. When the control server is in an overload state, it can still receive an appropriate service requirement. In this case, the user equipment can be preferentially accessed, so that the user equipment can successfully access the network, thereby enabling the user equipment to implement data transmission. Therefore, the gateway device can actively request the control server to perform access control on the user equipment.
