技术领域Technical field

本发明涉及通信技术领域，特别涉及一种接入控制方法、接入网节点及核心网节点。The present invention relates to the field of communication technology, in particular to an access control method, an access network node and a core network node.

背景技术Background technique

R16中，无线接入网(Radio Access Network，RAN，也称接入网节点)侧不负责判断一个用户设备(User Equipment，UE，终端)是否能接入某个小区，而是由核心网判断UE通过某个小区接入网络的合法性。当UE通过一个非公有网络(non-public network，NPN)小区请求接入网络时，RAN会向核心网节点提供该小区支持的NPN信息，核心网基于RAN提供的小区支持的NPN信息以及UE的签约信息判断UE是否能通过该小区接入网络。In R16, the radio access network (Radio Access Network, RAN, also known as access network node) side is not responsible for judging whether a user equipment (User Equipment, UE, terminal) can access a certain cell, but the core network judges The legitimacy of the UE accessing the network through a certain cell. When the UE requests access to the network through a non-public network (NPN) cell, the RAN will provide the core network node with the NPN information supported by the cell. The core network is based on the NPN information provided by the RAN and the UE’s The subscription information determines whether the UE can access the network through the cell.

R17中，若小区存在公共陆地移动网(Public Land Mobile Network，PLMN)和非独立式NPN(Public network integrated NPN，PNI-NPN)共享或PLMN和独立式的NPN(standalone NPN，SNPN)和PNI-NPN共享，网络侧可能错误判断一个原本可以接入网络的UE是不能接入网络的，导致UE接入失败。举例说明，比如一个UE的签约信息指示该UE可以接入的闭合接入组(Closed access group，CAG)为PLMN1部署的CAG1和CAG2，UE通过小区1申请接入网络，如果小区1可以支持的闭合接入组为PLMN1部署的CAG3以及PLMN 1接入，核心网侧基于UE的CAG签约信息和RAN提供的小区支持的CAG信息，会判断UE接入失败，但实际上该CAG UE是可以通过PLMN1接入网络的。In R17, if the cell has public land mobile network (Public Land Mobile Network, PLMN) and non-standalone NPN (Public network integrated NPN, PNI-NPN) sharing or PLMN and independent NPN (standalone NPN, SNPN) and PNI- With NPN sharing, the network side may misjudge that a UE that can originally access the network cannot access the network, resulting in UE access failure. For example, if the subscription information of a UE indicates that the closed access group (CG) that the UE can access is CAG1 and CAG2 deployed by PLMN1, the UE applies for access to the network through cell 1. If cell 1 can support The closed access group is for CAG3 deployed by PLMN1 and PLMN1 access. Based on the CAG subscription information of the UE and the CAG information supported by the cell provided by the RAN, the core network side will determine that the UE has failed to access, but in fact the CAG UE can pass PLMN1 accesses the network.

具体实施方式Detailed ways

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本发明进行详细描述。In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

在进行本发明实施例的说明时，首先对下面描述中所用到的一些概念进行解释说明。When describing the embodiments of the present invention, some concepts used in the following description are first explained.

1、非公有网络(non-public network，NPN)简介1. Introduction to non-public network (NPN)

工业环境下，许多应用(例如生产制造，自动化控制等)都有很高的性能需求，比如低延时、高可靠等。在本地网络下，随着设备密度的增加，这些性能需求是很难满足的，但可以使用无线链路代替传统的有线链路，通过第五代(5 Generation，5G)通信网络为这类垂直行业提供一种局域网(Local Area Network，LAN)类型的私有通信服务，满足垂直行业的通信需求。In an industrial environment, many applications (such as manufacturing, automation control, etc.) have high performance requirements, such as low latency and high reliability. In the local network, with the increase of equipment density, these performance requirements are difficult to meet, but wireless links can be used to replace traditional wired links. The fifth generation (5 Generation, 5G) communication network provides this type of vertical communication network. The industry provides a local area network (LAN) private communication service to meet the communication needs of vertical industries.

目前，3GPP同意采用如下两种NPN部署方式以支持垂直行业的通信应用：第一种是独立式的NPN(standalone NPN，SNPN)部署，该方式不依赖于公共网络，通过网络侧提供的非公有网络标识(如SNPN ID)便于用户设备(User Equipment，UE，终端)判断是否能够驻留在某个网络上，如legacy UE不能在SNPN网络对应的小区上正常驻留，而SNPN UE不能再在PLMN网络对应的小区上正常驻留；第二种是非独立式NPN(Public network integrated NPN，PNI-NPN)部署，该方式依赖于公共网络。该部署场景下引入了闭合接入组(Closed access group，CAG)概念，以便于控制UE接入特定的小区。如UE在订阅NPN服务时，会指示该UE所属的CAG，小区会提供其支持的CAG标识便于UE判断是否能够接入某个小区。如UE所属的接入组为CAG1，某小区支持的接入组为CAG1和CAG2，则UE可以判断该小区是可以接入的。如果某小区支持的接入组为CAG2，则UE可以判断该小区是不可以接入的。At present, 3GPP agrees to adopt the following two NPN deployment methods to support communication applications in vertical industries: The first is a standalone NPN (standalone NPN, SNPN) deployment, which does not depend on the public network and is provided by the network side. Network identification (such as SNPN ID) is convenient for user equipment (User Equipment, UE, terminal) to determine whether it can camp on a certain network. For example, legacy UE cannot normally camp on the cell corresponding to SNPN network, and SNPN UE can no longer stay on The cell corresponding to the PLMN network normally resides; the second type is non-independent NPN (Public network integrated NPN, PNI-NPN) deployment, which relies on the public network. In this deployment scenario, the concept of a closed access group (CAG) is introduced to facilitate controlling the UE to access a specific cell. For example, when the UE subscribes to the NPN service, it will indicate the CAG to which the UE belongs, and the cell will provide the CAG identification it supports to facilitate the UE to determine whether it can access a certain cell. If the access group to which the UE belongs is CAG1, and the access groups supported by a cell are CAG1 and CAG2, the UE can determine that the cell is accessible. If the access group supported by a cell is CAG2, the UE can determine that the cell is not accessible.

其中，对于非独立式NPN部署场景，如果配置了UE只能接入CAG小区，则该UE不能通过非CAG小区注册，而对于某个CAG小区，不允许不属于该小区的用户接入。Among them, for the non-standalone NPN deployment scenario, if the UE is configured to only access the CAG cell, the UE cannot register through the non-CAG cell, and for a certain CAG cell, users who do not belong to the cell are not allowed to access.

注意：在R16中，CAG小区可以理解为广播了其支持的CAG标识的小区。Note: In R16, a CAG cell can be understood as a cell that broadcasts the CAG identity it supports.

2、PNI-NPN接入控制简介2. Introduction to PNI-NPN access control

在R16中，如果一个UE通过一个CAG小区接入网络，则UE并不会将选择的CAG标识报告给无线接入网(RAN)侧，核心网节点(如接入和移动性管理功能(Access and Mobility Management Function，AMF))判断一个UE是否能通过CAG小区接入是基于核心网侧UE的CAG签约信息以及RAN侧提供的小区支持的CAG信息来判断。举例说明，一个UE的签约信息指示该UE可以接入的闭合接入组为CAG1和CAG2，UE通过小区1申请接入网络，小区1可以支持的闭合接入组为CAG1，则网络侧会确定UE是可以通过小区1接入网络的。如果小区1可以支持的闭合接入组为CAG3，则网络侧会判断UE是不可以通过小区1接入网络的。In R16, if a UE accesses the network through a CAG cell, the UE will not report the selected CAG identifier to the radio access network (RAN) side. Core network nodes (such as access and mobility management functions (Access) and Mobility Management Function (AMF)) judging whether a UE can access through the CAG cell is based on the CAG subscription information of the UE on the core network side and the CAG information supported by the cell provided by the RAN side. For example, the subscription information of a UE indicates that the closed access groups that the UE can access are CAG1 and CAG2, the UE applies for access to the network through cell 1, and the closed access group that cell 1 can support is CAG1, then the network side will determine The UE can access the network through cell 1. If the closed access group that cell 1 can support is CAG3, the network side will determine whether the UE can access the network through cell 1.

3、CAG UE简介3. Introduction to CAG UE

对于一个具有CAG能力的UE，可以配置有CAG allowed list和/或CAG only indication。CAG allowed list指示的是UE可以接入的接入组，比如CAG allowed list包含CAG1和CAG2，则表明UE可以接入的接入组为CAG1和CAG2。如果还配置了CAG only indication，则UE只能通过CAG接入网络。如果没有配置CAG only indication，则UE还可以通过PLMN接入网络。For a CAG capable UE, CAG allowed list and/or CAG only indication can be configured. The CAG allowed list indicates the access groups that the UE can access. For example, the CAG allowed list contains CAG1 and CAG2, which indicates that the access groups that the UE can access are CAG1 and CAG2. If CAG only indication is also configured, the UE can only access the network through CAG. If CAG only indication is not configured, the UE can also access the network through PLMN.

本发明针对当PLMN和PNI-NPN共享或PLMN和SNPN和PNI-NPN共享时，网络侧可能错误判断一个原本可以接入网络的UE是不能接入网络的，导致UE接入失败的问题，提供一种接入控制方法、接入网节点及核心网节点。The present invention addresses the problem that when PLMN and PNI-NPN are shared or PLMN and SNPN and PNI-NPN are shared, the network side may misjudge that a UE that can originally access the network cannot access the network, causing the UE to fail to access the network, and provide An access control method, access network node and core network node.

如图1所示，本发明实施例提供一种接入控制方法，应用于接入网节点，包括：As shown in FIG. 1, an embodiment of the present invention provides an access control method, which is applied to an access network node, and includes:

步骤101，向核心网节点发送第一小区的相关信息；Step 101: Send relevant information of the first cell to a core network node;

其中，所述第一小区为能够提供闭合接入组(CAG)接入的小区；所述第一小区的相关信息用于所述核心网节点进行终端的接入控制；Wherein, the first cell is a cell that can provide closed access group (CAG) access; relevant information of the first cell is used by the core network node to perform terminal access control;

需要说明的是，本发明实施例中所提到的网络类型接入倾向指的是终端以何种类型接入网络的意图；该网络类型接入倾向包括：终端期望通过公共陆地移动网(Public Land Mobile Network，PLMN)接入网络，或者终端期望通过CAG接入网络。It should be noted that the network type access tendency mentioned in the embodiment of the present invention refers to the intention of the terminal to access the network; this network type access tendency includes: the terminal expects to use a public land mobile network (Public land mobile network). Land Mobile Network (PLMN) access to the network, or the terminal expects to access the network through CAG.

需要说明的是，本发明实施例主要应用于PLMN和PNI-NPN共享、或者PLMN、SNPN和PNI-NPN共享的场景。It should be noted that the embodiments of the present invention are mainly applied to scenarios where PLMN and PNI-NPN are shared, or PLMN, SNPN, and PNI-NPN are shared.

可选地，步骤101的一种实现方式为：Optionally, an implementation manner of step 101 is:

在接收到终端发送的请求信息的情况下，向核心网节点发送第一小区的相关信息；In the case of receiving the request information sent by the terminal, send the relevant information of the first cell to the core network node;

其中，所述请求信息用于请求通过第一小区接入网络。Wherein, the request information is used to request to access the network through the first cell.

需要说明的是，此种情况限定的是，只有在终端通过第一小区向接入网节点发送接入请求时，才向接入网节点发送第一小区的相关信息，也就是说，此种情况是终端触发，接入网节点才会进行第一小区的相关信息的上报；当没有接收到终端发送的通过第一小区接入网络的请求信息这一条件的限定时，指的是接入网节点主动向核心网节点发送第一小区的相关信息。It should be noted that in this case, the limitation is that only when the terminal sends an access request to the access network node through the first cell, the relevant information of the first cell is sent to the access network node, that is, this type of When the situation is triggered by the terminal, the access network node will report the relevant information of the first cell; when the conditional limitation of the request information sent by the terminal to access the network through the first cell is not received, it refers to access The network node actively sends the relevant information of the first cell to the core network node.

因接入网节点会向终端发送两种不同的第一小区的相关信息，下面分别从这两种信息的角度，对本发明实施例的具体实现进行详细说明如下。Since the access network node will send two different kinds of related information of the first cell to the terminal, the specific implementation of the embodiment of the present invention will be described in detail below from the perspective of these two kinds of information.

一、第一小区的相关信息包括：所述第一小区支持至少一种网络类型接入的第一指示信息1. The related information of the first cell includes: first indication information that the first cell supports at least one type of network access

示例性的，需要说明的是，所述第一小区可以通过cell ID来标识。Exemplarily, it should be noted that the first cell may be identified by a cell ID.

具体地，需要说明的是，所述第一指示信息，包括以下一项：Specifically, it should be noted that the first indication information includes one of the following:

A11、第一小区支持CAG接入的指示信息；A11. Indication information that the first cell supports CAG access;

需要说明的是，此种指示信息指示的是第一小区只支持CAG接入。It should be noted that this type of indication information indicates that the first cell only supports CAG access.

A12、第一小区支持CAG和PLMN接入的指示信息；A12. Indication information that the first cell supports CAG and PLMN access;

需要说明的是，此种指示信息指示的是第一小区既支持CAG接入，同时也支持PLMN接入。示例性的，此种指示信息指示的是第一小区既支持PLMN接入，也支持PLMN部署的CAG接入。所述指示信息可以是一比特的指示，比如取值为“1”或存在时，表示第一小区支持PLMN接入，也支持PLMN部署的CAG接入。比如取值为“0”或不存在时，表示第一小区不能同时支持PLMN接入和PLMN部署的CAG接入。所述指示信息还可以是小区支持的网络类型接入信息，比如小区支持的网络类型接入为PLMN1和PLMN1部署的CAG1和CAG2。It should be noted that this kind of indication information indicates that the first cell supports both CAG access and PLMN access at the same time. Exemplarily, this kind of indication information indicates that the first cell supports both PLMN access and CAG access deployed by PLMN. The indication information may be a one-bit indication. For example, when the value is "1" or exists, it indicates that the first cell supports PLMN access and also supports CAG access deployed by PLMN. For example, when the value is "0" or does not exist, it means that the first cell cannot support both PLMN access and CAG access deployed by PLMN. The indication information may also be network type access information supported by the cell, for example, the network type access supported by the cell is PLMN1 and CAG1 and CAG2 deployed by PLMN1.

A13、第一小区支持CAG、PLMN和独立式的非公有网络(SNPN)接入的指示信息；A13. The indication information that the first cell supports CAG, PLMN and independent non-public network (SNPN) access;

需要说明的是，此种指示信息指示的是第一小区同时支持CAG、PLMN和SNPN接入。示例性的，此种指示信息指示的是第一小区既支持PLMN接入，也支持PLMN部署的CAG接入以及PLMN部署的SNPN接入。It should be noted that this type of indication information indicates that the first cell supports CAG, PLMN, and SNPN access at the same time. Exemplarily, this kind of indication information indicates that the first cell supports both PLMN access, CAG access deployed by PLMN and SNPN access deployed by PLMN.

情况一、需要说明的是，当接入网节点主动上报第一小区的相关信息时，该第一小区的相关信息中通常只包括第一指示信息，具体地，所述第一小区的相关信息中还应当包括：第一小区支持的CAG的标识信息；具体地，该CAG的标识信息可以为CAG的接入组列表，例如，小区广播的对应于终端选择的PLMN标识的接入组列表，若终端选择的是PLMN1，则小区广播的PLMN1对应的接入组列表中包括：CAG1和CAG2，所述第一小区支持的CAG标识信息为PLMN1部署的接入组列表CAG1和CAG2。Case 1. It should be noted that when the access network node actively reports the related information of the first cell, the related information of the first cell usually only includes the first indication information, specifically, the related information of the first cell It should also include: the identification information of the CAG supported by the first cell; specifically, the identification information of the CAG may be a list of CAG access groups, for example, a list of access groups broadcast by the cell corresponding to the PLMN identification selected by the terminal, If the terminal selects PLMN1, the access group list corresponding to PLMN1 broadcast by the cell includes CAG1 and CAG2, and the CAG identification information supported by the first cell is the access group lists CAG1 and CAG2 deployed by PLMN1.

进一步地，在此种情况下，当核心网节点接收接入网节点的第一小区的相关信息时，需要结合第一小区的相关信息和终端的签约信息，进行终端的接入控制，具体地，该接入控制指的是核心网节点确定终端是否通过所述第一小区接入网络；通过判断，接入网节点会得到终端通过所述第一小区接入网络，或终端不能通过所述第一小区接入网络的判断结果。Further, in this case, when the core network node receives the related information of the first cell of the access network node, it needs to combine the related information of the first cell and the subscription information of the terminal to perform the access control of the terminal, specifically The access control means that the core network node determines whether the terminal accesses the network through the first cell; through judgment, the access network node will obtain that the terminal accesses the network through the first cell, or the terminal cannot pass through the The judgment result of the first cell's access to the network.

具体地，当所述根据所述第一小区的相关信息和终端的签约信息，确定终端通过所述第一小区接入网络时(即判断终端通过第一小区接入成功)，包括以下一项：Specifically, when it is determined that the terminal accesses the network through the first cell according to the related information of the first cell and the subscription information of the terminal (that is, it is determined that the terminal has successfully accessed through the first cell), the following items are included: :

A21、若所述第一小区支持的CAG的标识信息中至少存在一个CAG的标识信息位于所述签约信息的终端允许的CAG的标识列表中，则确定终端通过所述第一小区接入网络；A21. If there is at least one CAG identification information in the CAG identification information supported by the first cell in the CAG identification list allowed by the terminal of the subscription information, it is determined that the terminal accesses the network through the first cell;

此种情况指的是，例如，接入网节点提供的小区1支持接入的CAG标识为PLMN1部署的CAG1和CAG2，而终端的签约信息中终端允许的CAG标识列表为PLMN1部署的CAG1和CAG2，则核心网节点判断终端可以通过小区1接入网络。This situation refers to, for example, that the CAG identities supported by cell 1 access provided by the access network node are CAG1 and CAG2 deployed by PLMN1, and the list of CAG identities allowed by the terminal in the subscription information of the terminal are CAG1 and CAG2 deployed by PLMN1 , The core network node determines that the terminal can access the network through cell 1.

A22、若所述第一小区支持的CAG的标识信息中不存在CAG的标识信息位于所述签约信息的终端允许的CAG的标识列表中、且第一小区支持PLMN、以及所述签约信息中不存在终端通过CAG接入网络的指示信息，则确定终端通过所述第一小区接入网络；A22. If there is no CAG identification information in the CAG identification information supported by the first cell, the CAG identification information is in the CAG identification list allowed by the terminal of the subscription information, and the first cell supports PLMN, and the subscription information is not included in the CAG identification information. If there is indication information that the terminal accesses the network through the CAG, it is determined that the terminal accesses the network through the first cell;

需要说明的是，所述签约信息中不存在终端通过CAG接入网络的指示信息指的是，终端签约信息中不存在终端只能通过CAG接入网络的指示信息。It should be noted that the absence of indication information that the terminal can access the network through CAG in the subscription information means that there is no indication that the terminal can only access the network through CAG in the terminal subscription information.

此种情况指的是，例如，接入网节点提供小区1支持接入的CAG标识为PLMN1部署的CAG1和CAG2以及PLMN1接入，而终端的签约信息中终端允许的CAG列表为PLMN1部署的CAG3和CAG4、且终端的签约信息中没有终端只能通过CAG接入网络的指示信息，则核心网节点判断终端可以通过小区1接入网络。This situation refers to, for example, that the CAG identifiers provided by the access network node to support access to cell 1 are CAG1 and CAG2 deployed by PLMN1 and PLMN1 access, and the CAG list allowed by the terminal in the terminal's subscription information is CAG3 deployed by PLMN1 And CAG4, and there is no indication information that the terminal can only access the network through CAG in the subscription information of the terminal, the core network node determines that the terminal can access the network through cell 1.

Information, the second indication information is used to indicate the network type access tendency of the terminal; specifically, the related information of the first cell should also include: identification information of the CAG supported by the first cell.

需要说明的是，终端的网络类型接入倾向的具体确定方式为：It should be noted that the specific method for determining the terminal's network type access tendency is:

方式一、若终端上报给接入网节点的关于选择的PLMN信息对应的是小区广播的legacy PLMN列表中的一个PLMN，则接入网节点确定终端期望通过PLMN接入网络；Method 1: If the selected PLMN information reported by the terminal to the access network node corresponds to a PLMN in the legacy PLMN list broadcast by the cell, the access network node determines that the terminal expects to access the network through the PLMN;

例如，小区1广播的legacy PLMN列表为PLMN1、PLMN2，若终端上报的选择PLMN对应于该列表中的PLMN1，则表明终端期望通过PLMN1接入网络；For example, the legacy PLMN list broadcast by cell 1 is PLMN1 and PLMN2. If the selected PLMN reported by the terminal corresponds to PLMN1 in the list, it indicates that the terminal expects to access the network through PLMN1;

方式二、若终端上报给接入网节点的关于选择的PLMN信息对应的是小区广播的NPN列表中对应的一个PLMN，则接入网节点确定终端期望通过NPN接入网络；Manner 2: If the selected PLMN information reported by the terminal to the access network node corresponds to a corresponding PLMN in the NPN list broadcast by the cell, the access network node determines that the terminal expects to access the network through the NPN;

例如，小区1广播的NPN列表为PLMN1部署的CAG1和CAG2以及PLMN2部署的CAG3，若终端上报的选择PLMN对该列表中的PLMN1，则表明终端期望通过PLMN1部署的CAG1或CAG2接入网络。For example, the NPN list broadcast by cell 1 is CAG1 and CAG2 deployed by PLMN1 and CAG3 deployed by PLMN2. If the PLMN1 in the list is selected as the PLMN reported by the terminal, it indicates that the terminal expects to access the network through CAG1 or CAG2 deployed by PLMN1.

A41、若所述相关信息中存在所述第一小区支持PLMN接入的指示信息、且终端期望通过PLMN接入网络、以及终端不存在NPN的签约信息(所述NPN签约信息包括SNPN或/和CAG签约信息，对于没有NPN签约信息的终端，其只能通过PLMN接入网络)，则确定终端通过所述第一小区接入网络；A41. If there is indication information that the first cell supports PLMN access in the related information, and the terminal expects to access the network through PLMN, and the terminal does not have NPN subscription information (the NPN subscription information includes SNPN or/and CAG subscription information, for a terminal without NPN subscription information, it can only access the network through the PLMN), then it is determined that the terminal accesses the network through the first cell;

此种情况指的是，例如，接入网节点提供小区1支持接入的CAG标识为PLMN1部署的CAG1和CAG2和PLMN1接入，终端期望通过PLMN接入网络，且终端的签约信息中不存在针对NPN相关的签约信息，则核心网节点判断终端可以通过小区1接入网络。This situation refers to, for example, that the access network node provides the CAG identification for cell 1 to support access as CAG1, CAG2 and PLMN1 deployed by PLMN1. The terminal expects to access the network through the PLMN, and the terminal’s subscription information does not exist. For NPN-related contract information, the core network node determines that the terminal can access the network through cell 1.

A42、若所述相关信息中存在所述第一小区支持PLMN接入的指示信息、且终端期望通过PLMN接入网络、以及所述签约信息中不存在终端通过CAG接入的指示信息，并且终端存在非公有网络NPN的签约信息(所述NPN签约信息包括SNPN或/和CAG签约信息，对于没有NPN签约信息的终端，其只能通过PLMN接入网络)，则确定终端通过所述第一小区接入网络；A42. If there is indication information that the first cell supports PLMN access in the related information, and the terminal expects to access the network through the PLMN, and there is no indication information that the terminal accesses through CAG in the subscription information, and the terminal If there is non-public network NPN subscription information (the NPN subscription information includes SNPN or/and CAG subscription information, for a terminal without NPN subscription information, it can only access the network through PLMN), then it is determined that the terminal passes through the first cell Access to the network;

A43、若所述第一小区支持的CAG的标识信息中至少存在一个CAG的标识信息位于所述签约信息的终端允许的CAG的标识列表中、且终端期望通过CAG接入网络，则确定终端通过所述第一小区接入网络；A43. If there is at least one CAG identification information in the CAG identification information supported by the first cell in the CAG identification list allowed by the terminal of the subscription information, and the terminal expects to access the network through CAG, it is determined that the terminal passes The first cell accesses the network;

此种情况指的是，例如，接入网节点提供小区1支持接入的接入组标识为PLMN1部署的CAG1和CAG2接入，终端期望通过CAG接入，且终端的签约信息中终端允许的CAG标识列表为CAG1和CAG3，则核心网节点判断终端可以通过小区1接入网络。This situation refers to, for example, that the access network node provides access group IDs supported by cell 1 for access to CAG1 and CAG2 deployed by PLMN1, and the terminal expects to access through CAG, and the terminal's contract information is allowed by the terminal The CAG identifier list is CAG1 and CAG3, and the core network node determines that the terminal can access the network through cell 1.

A51、若所述相关信息中存在所述第一小区支持PLMN接入的指示信息、且终端期望通过PLMN接入网络、以及所述签约信息中存在终端通过CAG接入的指示信息，则确定终端不能通过所述第一小区接入网络；A51. If there is indication information that the first cell supports PLMN access in the related information, and the terminal expects to access the network through the PLMN, and there is indication information that the terminal accesses through CAG in the subscription information, determine the terminal Cannot access the network through the first cell;

此种情况指的是，例如，接入网节点提供小区1支持接入的CAG标识为PLMN1部署的CAG1和CAG2和PLMN1接入，终端期望通过PLMN接入，且小区1的相关信息中存在终端只能通过CAG接入的指示信息，则核心网节点判断终端不能通过小区1接入网络。This situation refers to, for example, that the access network node provides the CAG identification for cell 1 to support access as CAG1, CAG2 and PLMN1 deployed by PLMN1, and the terminal expects to access through the PLMN, and there is a terminal in the relevant information of cell 1. Only through the instruction information of CAG access, the core network node determines that the terminal cannot access the network through cell 1.

A52、若所述第一小区支持的CAG的标识信息中不存在CAG的标识信息位于所述签约信息的终端允许的CAG的标识列表中、且终端期望通过CAG接入网络，则确定终端不能通过所述第一小区接入网络；A52. If there is no CAG identification information in the CAG identification information supported by the first cell and the CAG identification information is in the CAG identification list allowed by the terminal of the subscription information, and the terminal expects to access the network through CAG, it is determined that the terminal cannot pass The first cell accesses the network;

此种情况指的是，例如，接入网节点提供小区1支持接入的CAG标识为PLMN1部署的CAG1和CAG2接入，终端期望通过CAG接入，且终端的签约信息中存在终端允许接入的CAG标识列表为CAG3和CAG4，则核心网节点判断终端不能通过小区1接入网络。This situation refers to, for example, that the access network node provides the CAG identifiers supported by cell 1 for access to CAG1 and CAG2 deployed by PLMN1, and the terminal expects to access through CAG, and the terminal's subscription information contains the terminal's permission to access If the CAG identifier list is CAG3 and CAG4, the core network node judges that the terminal cannot access the network through cell 1.

进一步需要说明的是，在核心网节点确定终端是否通过所述第一小区接入网络后，核心网节点通过接入网节点向终端反馈接入请求响应，当核心网节点确定终端通过所述第一小区接入网络时，该接入请求响应用于指示同意终端接入网络；当核心网节点确定终端不能通过所述第一小区接入网络时，该接入请求响应用于指示拒绝终端接入网络，需要说明的是，在此种情况下，核心网节点还可以将拒绝原因发送给终端，例如，该拒绝原因可以为：第一小区没有提供允许终端接入的CAG标识。It should be further noted that after the core network node determines whether the terminal accesses the network through the first cell, the core network node feeds back an access request response to the terminal through the access network node, and when the core network node determines that the terminal passes the first cell When a cell accesses the network, the access request response is used to indicate that the terminal is allowed to access the network; when the core network node determines that the terminal cannot access the network through the first cell, the access request response is used to indicate that the terminal is denied access to the network. When entering the network, it should be noted that, in this case, the core network node may also send a rejection reason to the terminal. For example, the rejection reason may be: the first cell does not provide a CAG identifier that allows the terminal to access.

下面对此种情况的具体实现方式举例说明如下。The following is an example of the specific implementation of this situation.

当PLMN和CAG存在共享时，接入网节点(RAN)向核心网节点(CN)提供是否与PLMN共享的指示，如图2所示，具体地实现流程为：When PLMN and CAG are shared, the access network node (RAN) provides an indication to the core network node (CN) whether to share with the PLMN, as shown in Figure 2. The specific implementation process is:

步骤21，终端通过一个广播了CAG标识的小区请求接入网络，例如，小区1广播了CAG标识CAG1，终端通过该小区1请求接入网络，其中所述小区1可以通过小区标识(如cell identity)来识别。Step 21: The terminal requests access to the network through a cell that broadcasts the CAG identity. For example, cell 1 broadcasts the CAG identity CAG1, and the terminal requests access to the network through the cell 1. The cell 1 can be accessed through the cell identity (such as cell identity ) To identify.

步骤22，RAN侧确定所述小区的相关信息，并提供给CN(如AMF)，其中，所述小区的相关信息包含以下一项或多项：Step 22: The RAN side determines the relevant information of the cell and provides it to the CN (such as AMF), where the relevant information of the cell includes one or more of the following:

A61、小区支持的CAG的标识信息，例如为：小区支持的接入组标识列表，如小区广播的对应于终端选择的PLMN标识的接入组列表，如终端选择的PLMN1，小区广播的PLMN1对应的接入组标识CAG1、CAG2。A61. The identification information of the CAG supported by the cell is, for example, the access group identification list supported by the cell, such as the access group list broadcast by the cell corresponding to the PLMN identification selected by the terminal, such as PLMN1 selected by the terminal, corresponding to PLMN1 broadcast by the cell The access group ID of CAG1 and CAG2.

A62、小区只提供CAG接入的指示信息；A62. The cell only provides instructions for CAG access;

例如，终端选择的PLMN1，小区提供PLMN1部署的CAG1和CAG2接入。For example, in the PLMN1 selected by the terminal, the cell provides access to CAG1 and CAG2 deployed by PLMN1.

A63、小区提供CAG和PLMN接入的指示信息；A63. The cell provides instructions for CAG and PLMN access;

例如，终端选择的PLMN1，小区提供PLMN1接入和PLMN1部署的CAG1和CAG2接入。For example, in the PLMN1 selected by the terminal, the cell provides PLMN1 access and CAG1 and CAG2 access deployed by PLMN1.

需要说明的是，在实际实现时，上述可选地组合为：小区的相关信息包含A61和A62，或者，小区的相关信息包含A61和A63。It should be noted that in actual implementation, the above optional combination is as follows: the related information of the cell includes A61 and A62, or the related information of the cell includes A61 and A63.

额外地，RAN侧还可以向CN提供终端的网络类型接入倾向，所述终端的网络类型接入倾向指示的是终端期望通过CAG接入网络还是期望通过PLMN接入网络。Additionally, the RAN side may also provide the CN with the network type access tendency of the terminal, and the network type access tendency of the terminal indicates whether the terminal desires to access the network through CAG or through PLMN.

步骤23，CN接收RAN侧提供的接入小区相关的信息，结合终端的签约信息判断终端是否能通过所述小区接入网络；Step 23: The CN receives the information related to the access cell provided by the RAN side, and determines whether the terminal can access the network through the cell based on the subscription information of the terminal;

具体包括：步骤231、CN判断终端通过CAG小区接入成功的情况包含以下任意一种：Specifically, it includes: Step 231. The situation in which the CN judges that the terminal has successfully accessed through the CAG cell includes any one of the following:

步骤232、CN判断终端通过所述CAG小区接入失败的情况包含以下任意一种：Step 232: The situation in which the CN judges that the terminal fails to access through the CAG cell includes any one of the following:

情况一、RAN提供的小区支持的CAG的标识信息中不存在CAG的标识信息位于终端的签约信息的终端允许的CAG的标识列表中、且小区1不支持PLMN接入；Case 1: The CAG identification information of the cell supported by the RAN does not exist. The CAG identification information is in the CAG identification list allowed by the terminal of the terminal's subscription information, and cell 1 does not support PLMN access;

情况三、RAN提供的小区的相关信息中存在小区1不支持PLMN接入的指示信息。Case 3: In the cell-related information provided by the RAN, there is an indication that cell 1 does not support PLMN access.

额外地，若RAN侧还提供了终端的网络类型接入倾向，则CN判断终端通过所述CAG小区接入失败的情况包含以下任意一种：Additionally, if the RAN side also provides the terminal's network type access tendency, the CN's judgment that the terminal fails to access through the CAG cell includes any one of the following:

情况一、RAN提供的小区相关信息中存在小区1支持PLMN接入的指示信息、且终端期望通过PLMN接入网络、以及终端的签约信息中存在终端通过CAG接入的指示信息；Case 1: In the cell related information provided by the RAN, there is indication information that cell 1 supports PLMN access, and the terminal expects to access the network through PLMN, and there is indication information that the terminal accesses through CAG in the subscription information of the terminal;

所述响应消息可以是：同意终端接入网络，例如，终端通过广播了接入组标识的小区1请求接入网络，网络反馈同意终端接入网络，则表明网络侧通过UE通过小区1接入网络；The response message may be: the terminal is approved to access the network, for example, the terminal requests to access the network through cell 1 that broadcasts the access group identifier, and the network feeds back that the terminal is approved to access the network, which indicates that the network side accesses the network through the UE through cell 1. The internet;

拒绝终端接入网络，例如，终端通过广播了接入组标识的小区1请求接入网络，网络侧反馈拒绝终端接入网络，则表明网络侧拒绝终端通过小区1接入网络；此外，网络侧还会提供拒绝原因，如小区没有提供允许终端接入的接入组标识等。The terminal is denied access to the network. For example, the terminal requests access to the network through cell 1 that broadcasts the access group ID, and the network side feeds back that the terminal is denied access to the network, which indicates that the network side refuses the terminal to access the network through cell 1. In addition, the network side The reason for rejection is also provided, for example, the cell does not provide an access group ID that allows the terminal to access.

二、所述第一小区的相关信息包括：与终端的网络类型接入倾向对应的第一小区的信息2. The related information of the first cell includes: information of the first cell corresponding to the terminal's network type access tendency

具体地，需要说明的是，步骤101的实现方式可以为：Specifically, it should be noted that the implementation of step 101 may be:

确定所述终端的网络类型接入倾向，获取与所述网络类型接入倾向对应的第一小区的信息，将与所述网络类型接入倾向对应的第一小区的信息发送给核心网节点。The network type access tendency of the terminal is determined, the information of the first cell corresponding to the network type access tendency is acquired, and the information of the first cell corresponding to the network type access tendency is sent to the core network node.

进一步需要说明的是，在此种情况下，所述与终端的网络类型接入倾向对应的第一小区的信息，包括以下一项：It should be further noted that, in this case, the information of the first cell corresponding to the network type access tendency of the terminal includes one of the following:

B11、若终端的网络类型接入倾向为期望通过PLMN接入网络、且所述第一小区支持PLMN和CAG接入或支持PLMN、CAG和独立式的非公有网络SNPN接入时，所述第一小区的信息中不包括第一小区的CAG信息；B11. If the terminal's network type access tendency is to expect to access the network through PLMN, and the first cell supports PLMN and CAG access or supports PLMN, CAG and independent non-public network SNPN access, the first cell The information of a cell does not include the CAG information of the first cell;

也就是说，当终端期望通过PLMN接入网络时，接入网节点向核心网节点发送的第一小区的信息中不包含第一小区的CAG信息，具体地，该CAG信息可以为第一小区支持的CAG的标识信息。That is to say, when the terminal expects to access the network through the PLMN, the information of the first cell sent by the access network node to the core network node does not contain the CAG information of the first cell. Specifically, the CAG information may be the first cell The identification information of the supported CAG.

例如，若终端期望通过PLMN1接入网络，小区广播的PLMN1对应的接入组列表中包括：CAG1和CAG2，则所述第一小区支持的CAG标识信息为PLMN1部署的接入组列表CAG1和CAG2。For example, if the terminal expects to access the network through PLMN1, and the access group list corresponding to PLMN1 broadcast by the cell includes CAG1 and CAG2, the CAG identification information supported by the first cell is the access group list CAG1 and CAG2 deployed by PLMN1 .

B12、若终端的网络类型接入倾向为期望通过CAG接入网络、且所述第一小区支持PLMN和CAG接入或支持PLMN、CAG和SNPN接入时，所述第一小区的信息包括第一小区支持的CAG的标识信息；B12. If the terminal's network type access tendency is that it expects to access the network through CAG, and the first cell supports PLMN and CAG access or supports PLMN, CAG and SNPN access, the information of the first cell includes the first cell Identification information of CAG supported by a cell;

也就是说，当终端期望通过CAG接入网络时，接入网节点向核心网节点发送的第一小区的信息中包含第一小区的CAG信息，具体地为第一小区的信息中包含第一小区支持的CAG的标识信息；例如，小区1提供PLMN1部署的CAG1和CAG2接入和PLMN1接入，终端期望通过CAG接入网络，则接入网节点向核心网节点提供小区1支持的PLMN1部署的CAG1和CAG2列表。That is to say, when the terminal expects to access the network through CAG, the information of the first cell sent by the access network node to the core network node includes the CAG information of the first cell, specifically, the information of the first cell includes the first cell. Identification information of the CAG supported by the cell; for example, cell 1 provides CAG1 and CAG2 access for PLMN1 deployment and PLMN1 access, and the terminal expects to access the network through CAG, then the access network node provides the core network node with the PLMN1 deployment supported by cell 1 List of CAG1 and CAG2.

B21、若所述第一小区的信息中至少存在一个CAG的标识信息位于所述签约信息的终端允许的CAG的标识列表中，则确定终端通过所述第一小区接入网络；B21.

例如，小区1提供PLMN1部署的CAG1和CAG2接入和PLMN1接入，终端指示期望通过CAG接入，则RAN向CN提供小区1支持的PLMN1部署的CAG1和CAG2列表。For example, cell 1 provides CAG1 and CAG2 access deployed by PLMN1 and PLMN1 access, and the terminal indicates that it is expected to access through CAG, then the RAN provides the CN with a list of CAG1 and CAG2 deployed by PLMN1 supported by cell1.

步骤34，结合终端的签约信息，CN判断终端是否能通过所述小区接入网络；Step 34: Combining the subscription information of the terminal, the CN judges whether the terminal can access the network through the cell;
