Description

一种终端接入方法及相应的终端、基站和主核心网Terminal access method and corresponding terminal, base station and main core network 技术领域Technical field
本申请涉及但不限于移动通信系统，更具体地，涉及一种终端接入方法及相应的终端、基站和主核心网。The present application relates to, but is not limited to, a mobile communication system, and more particularly, to a terminal access method and corresponding terminal, base station, and primary core network.
背景技术Background technique
第三代伙伴计划(3GPP)长期演进(LTE)网络共享方案分为同PLMN(Public Land Mobile Network，公共陆地移动网络)和不同PLMN两种情况。对于不同PLMN的网络共享，意味着基站连接的是两个或多个核心网网络，终端接入时会将选择的PLMN带到基站，然后基站再根据选择的PLMN来确定终端接入的核心网(对LTE网络是要确定接入的MME)；同PLMN的网络共享，表示基站连接的是一个移动网络，基站连接的不同核心网(对LTE网络是连接不同的MME)在该移动网络内为“负荷分担”的关系，即当用户接入时，不论基站选择PLMN匹配范围内的哪个核心网，都可以正常建立业务。The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) network sharing scheme is divided into the same situation as the PLMN (Public Land Mobile Network) and the different PLMN. For network sharing of different PLMNs, it means that the base station is connected to two or more core network networks, and when the terminal accesses, the selected PLMN is brought to the base station, and then the base station determines the core network accessed by the terminal according to the selected PLMN. (For the LTE network, the MME to determine access); sharing with the network of the PLMN, indicating that the base station is connected to a mobile network, and different core networks connected to the base station (connecting different MMEs to the LTE network) are in the mobile network. The "load sharing" relationship, that is, when the user accesses, regardless of which core network in the range in which the base station selects the PLMN, the service can be established normally.
但是一些特殊应用场景下，如集群行业用户网络与集群运营商网络共享时，存在特殊需求，此时虽然多个核心网共用一个PLMN，但多个核心网互不相通，更不存在负荷分担关系。目前标准中的网络共享方案没有提供针对这种场景的终端接入方案。However, in some special application scenarios, when the cluster industry user network is shared with the cluster operator network, there are special requirements. In this case, although multiple core networks share one PLMN, multiple core networks are not connected to each other, and there is no load sharing relationship. . The network sharing scheme in the current standard does not provide a terminal access scheme for such a scenario.

下面再用几个应用示例进行说明。Here are a few more application examples to illustrate.
应用示例一Application example one
本示例的工作流程如图7所示，包括以下步骤：The workflow of this example is shown in Figure 7, and includes the following steps:
第1步，终端在发送给基站的接入请求中携带PLMN标识、用户标识信息及不需要匹配核心网标识的指示信息；In the first step, the terminal carries the PLMN identifier, the user identifier information, and the indication information that does not need to match the core network identifier in the access request sent to the base station;
其中，PLMN标识用于表示请求接入的移动网络。基站可以配置一个或多个PLMN(也可以是其他移动网络)，本示例假定终端请求接入的PLMN有多个核心网且所述多个核心网不存在负荷分担关系，也即终端只能接入其对应的核心网才能够正常通信。The PLMN identity is used to indicate the mobile network requesting access. The base station can be configured with one or more PLMNs (other mobile networks). This example assumes that the PLMN that the terminal requests to access has multiple core networks, and the multiple core networks do not have a load sharing relationship. Only the corresponding core network can communicate normally.
本示例中，接入请求中携带表示是否需要匹配核心网标识的第一字段和表示核心网标识的第二字段，其中，第一字段的值表示不需要匹配核心网标识，此时即可确定接入请求未携带待匹配的核心网标识。如果第一字段的值表示需要匹配核心网标识，但第二字段中的核心网标识无效如为约定的无效值(如空值)，也确定接入请求未携带待匹配的核心网标识。在第一字段的值表示需要匹配核心网标识且第二字段中的核心网标识有效如非约定的无效值时，才确定接入请求携带待匹配的核心网标识。In this example, the access request carries a first field indicating whether a core network identifier needs to be matched, and a second field indicating a core network identifier, where the value of the first field indicates that the core network identifier does not need to be matched, and the identifier can be determined at this time. The access request does not carry the core network identifier to be matched. If the value of the first field indicates that the core network identifier needs to be matched, but the core network identifier in the second field is invalid as the agreed invalid value (such as a null value), it is also determined that the access request does not carry the core network identifier to be matched. When the value of the first field indicates that the core network identifier needs to be matched and the core network identifier in the second field is valid, such as a non-agreed invalid value, it is determined that the access request carries the core network identifier to be matched.
在另一示例中，接入请求中可以只携带表示核心网标识的字段，如果该字段中的核心网标识有效，则确定接入请求携带待匹配的核心网标识，如果无效，则确定接入请求未携带待匹配的核心网标识。In another example, the access request may only carry a field indicating the identity of the core network. If the core network identifier in the field is valid, it is determined that the access request carries the core network identifier to be matched, and if not, the access is determined. The request does not carry the core network identifier to be matched.
第2步，基站收到接入请求后，根据PLMN确定终端请求接入的移动网 络，在所述接入请求未携带待匹配的核心网标识时，判断所述主核心网是否可路由，本示例假定可路由即选路成功，此时向主核心网发送接入请求；In the second step, after receiving the access request, the base station determines, according to the PLMN, the mobile network that the terminal requests to access. If the access request does not carry the core network identifier to be matched, it is determined whether the primary core network is routable. This example assumes that the routable route is successful, and the access request is sent to the primary core network.
如果基站没有查找到与所述PLMN标识匹配的移动网络，则接入失败。If the base station does not find a mobile network that matches the PLMN identity, the access fails.
第3步，主核心网收到接入请求后，根据用户标识信息(如国际移动用户识别码(IMSI，International Mobile Subscriber Identification Number)号段但不限于此)等信息，查找配置的用户标识信息与所述移动网络的多个核心网的对应关系(如号段与核心网的对应关系)，本示例假定查找到的核心网为次核心网，主核心网发送重定向消息带给基站，所述重定向消息携带所述次核心网的标识以指示终端接入所述次核心网；Step 3: After receiving the access request, the primary core network searches for the configured user identification information according to the information of the user identification information (such as the International Mobile Subscriber Identification Number (IMSI), but not limited to this). Corresponding relationship with the plurality of core networks of the mobile network (such as the correspondence between the segment and the core network), this example assumes that the found core network is the secondary core network, and the primary core network sends a redirect message to the base station. The redirect message carries an identifier of the secondary core network to indicate that the terminal accesses the secondary core network;
第4步，基站收到重定向消息后，判断其中指示的核心网(可以是次核心网，有多个主核心网时，也可以是另一主核心网)可路由，向所述次核心网重新发送接入请求以完成接入流程。Step 4: After receiving the redirect message, the base station determines that the core network indicated therein (which may be a secondary core network, when there are multiple primary core networks, or another primary core network) may be routed to the secondary core. The network resends the access request to complete the access procedure.
第5步，终端、基站和所述次核心网交互完成接入。In the fifth step, the terminal, the base station, and the secondary core network interact to complete the access.
应用示例二Application example two
本示例的工作流程如图8所示，包括以下步骤：The workflow of this example is shown in Figure 8, which includes the following steps:
第1步，终端在发送给基站的接入请求中携带PLMN标识、用户标识信息、需要匹配核心网标识的指示信息及核心网标识；In the first step, the terminal carries the PLMN identifier, the user identifier information, the indication information that needs to match the core network identifier, and the core network identifier in the access request sent to the base station;
第2步，基站收到接入请求后，根据PLMN确定终端请求接入的移动网络，在所述接入请求携带待匹配的核心网标识时，判断所述核心网标识匹配的核心网是否可路由，本示例假定该核心网为次核心网(也可能是主核心网)且可路由即选路成功，此时向所述次核心网发送接入请求；Step 2: After receiving the access request, the base station determines, according to the PLMN, the mobile network that the terminal requests to access, and when the access request carries the core network identifier to be matched, determines whether the core network that matches the core network identifier is available. Routing, this example assumes that the core network is a secondary core network (and possibly a primary core network) and the routing is successful, and an access request is sent to the secondary core network.
第3步，终端、基站和所述次核心网交互以完成接入。In step 3, the terminal, the base station, and the secondary core network interact to complete the access.
应用示例三Application example three
本示例的工作流程如图9所示，包括以下步骤：The workflow of this example is shown in Figure 9, and includes the following steps:
第1步，终端在发送给基站的接入请求中携带PLMN标识、用户标识信息、需要匹配核心网标识的指示信息及核心网标识；In the first step, the terminal carries the PLMN identifier, the user identifier information, the indication information that needs to match the core network identifier, and the core network identifier in the access request sent to the base station;
第2步，基站收到接入请求后，根据PLMN确定终端请求接入的移动网 络，在所述接入请求携带待匹配的核心网标识时，判断所述核心网标识是否匹配到可路由的核心网，本示例假定匹配不到即选路失败；In the second step, after receiving the access request, the base station determines, according to the PLMN, the mobile network that the terminal requests to access. If the access request carries the core network identifier to be matched, it is determined whether the core network identifier matches the routable core network, and the example assumes that the matching fails, that is, the routing fails;
匹配不到可路由的核心网，可能是从配置信息中查找不到所述移动网络下的具有该核心网标识的核心网，也可能是查找到的核心网不可路由。If the core network with the core network identifier is not found in the configuration information, the core network with the core network identifier may not be found in the configuration information.
第3步，基站判断所述移动网络的主核心网是否可路由，本示例假定可路由即选路成功，此时向主核心网发送接入请求；In the third step, the base station determines whether the primary core network of the mobile network is routable. This example assumes that the routable route is successful, and the access request is sent to the primary core network.
第4-6步，同应用示例一的第3-5步。Steps 4-6, the same as step 3-5 of the application example one.
应用示例四Application example four
本示例针对不需要匹配核心网标识但主核心网不可路由的情况，基站可以向次核心网发送接入请求。This example is for a case where the core network identity does not need to be matched but the primary core network is not routable, and the base station can send an access request to the secondary core network.
本示例的工作流程包括以下步骤：The workflow for this example includes the following steps:
第1步，终端在发送给基站的接入请求中携带PLMN标识、用户标识信息及不需要匹配核心网标识的指示信息；In the first step, the terminal carries the PLMN identifier, the user identifier information, and the indication information that does not need to match the core network identifier in the access request sent to the base station;
第2步，基站收到接入请求后，根据PLMN确定终端请求接入的移动网络，在所述接入请求未携带待匹配的核心网标识时，判断所述主核心网是否可路由，本示例假定不可路由即选路失败；In the second step, after receiving the access request, the base station determines, according to the PLMN, the mobile network that the terminal requests to access, and determines whether the primary core network is routable when the access request does not carry the core network identifier to be matched. The example assumes that non-routing, that is, routing failure;
主核心网不可路由可能是该PLMN下没有配置主核心网，也可能是配置了主核心网但基站到该主核心网的链路故障。The main core network may not be routed. The primary core network may not be configured under the PLMN, or the link of the primary core network but the base station to the primary core network may be faulty.
第3步，基站向所述移动网络可路由的次核心网发送接入请求。In step 3, the base station sends an access request to the secondary core network routable by the mobile network.
如果次核心网根据接入请求中的用户标识信息判断该用户是自己服务的用户，会向基站返回接入响应，如果不是自己服务的用户，可以返回匹配失败的通知，基站还可以继续向所述移动网络中其他可路由的次核心网发送接入请求。If the secondary core network determines that the user is the user that serves the user according to the user identification information in the access request, the access response is returned to the base station, and if the user is not the user, the notification of the matching failure may be returned, and the base station may continue to the office. Other routable sub-core networks in the mobile network send access requests.
应用示例五Application example five
本示例针对需要匹配核心网标识但匹配不到可路由的核心网，且主核心网也不可路由的情况。This example is for a core network that needs to match the core network identity but does not match the routable core, and the primary core network is also not routable.
本示例的工作流程包括以下步骤： The workflow for this example includes the following steps:
第1步，终端在发送给基站的接入请求中携带PLMN标识、用户标识信息、需要匹配核心网标识的指示信息及核心网标识；In the first step, the terminal carries the PLMN identifier, the user identifier information, the indication information that needs to match the core network identifier, and the core network identifier in the access request sent to the base station;
第2步，基站收到接入请求后，根据PLMN确定终端请求接入的移动网络，在所述接入请求携带待匹配的核心网标识时，判断所述核心网标识是否匹配到可路由的核心网，本示例假定匹配不到即选路失败；In the second step, after receiving the access request, the base station determines, according to the PLMN, the mobile network that the terminal requests to access, and when the access request carries the core network identifier to be matched, determines whether the core network identifier matches the routable Core network, this example assumes that the match fails and the route fails;
第3步，基站判断所述移动网络的主核心网是否可路由，本示例假定不可路由即选路再次失败；In step 3, the base station determines whether the primary core network of the mobile network is routable, and the example assumes that the non-routable, that is, the routing fails again;
第4步，基站向所述移动网络可路由的次核心网发送接入请求。In step 4, the base station sends an access request to the secondary core network routable by the mobile network.
如果次核心网根据接入请求中的用户标识信息判断该用户是自己服务的用户，会向基站返回接入响应，如果不是自己服务的用户，可以返回匹配失败的通知，基站还可以继续向所述移动网络中其他可路由的次核心网发送接入请求。If the secondary core network determines that the user is the user that serves the user according to the user identification information in the access request, the access response is returned to the base station, and if the user is not the user, the notification of the matching failure may be returned, and the base station may continue to the office. Other routable sub-core networks in the mobile network send access requests.
