本申请实施例以5G网络架构为例，如图2所示，终端可通过接入网(Access Network，AN)接入5GC。该AN具体可以是RAN。5GC包括用户面网元功能(User Plane Function，UPF)与控制面网元功能(Control Plane Function，CPF)。其中，UPF主要负责分组数据包的转发、服务质量(Quality of Service，QoS)控制、计费信息统计等。CPF主要负责用户注册认证、移动性管理及向UPF下发数据包转发策略、QoS控制策略等，CPF具体可包括网络切片选择功能(Network Slice Selection Function，NSSF)、网络开放功能(Network Exposure Function，NEF)、网络存储功能(Network Repository Function，NRF)、策略控制功能(Policy Control Function，PCF)、统一的用户数据管理(Unified Data Management，UDM)功能、应用功能(Application Function，AF)、鉴权服务器功能(Authentication Server Function，AUSF)、接入与移动性管理功能(Access and Mobility Management Function，AMF)与会话管理功能(Session Management Function，SMF)等。
其中，AMF负责终端接入时的注册流程及终端移动过程中的位置管理。SMF负责终端发起业务时与网络侧建立相应的会话连接，为用户提供具体服务，尤其是基于SMF与UPF之间的N4接口向UPF下发数据包转发策略、QoS策略等。AUSF主要负责对终端进行鉴权，确定终端合法性。UDM主要用来存储终端的签约数据。PCF主要用来下发业务相关的策略给AMF或SMF。AF用于发送应用相关需求给PCF，使得PCF生成对应的策略。
具体的，终端与AMF之间的接口为N1接口，AN与AMF之间的接口为N2接口，AN与UPF之间的接口为N3接口，UPF与SMF之间的接口为N4接口，UPF与DN之间的接口为N6接口。NSSF通过Nnssf接口与CPF中的其他网元通信，NEF通过Nnef接口与CPF中的其他网元通信，NRF通过Nnrf接口与CPF中的其他网元通信，PCF通过Npcf接口与CPF中的其他网元通信，UDM通过Nudm接口与CPF中的其他网元通信，AF通过Naf接口与CPF中的其他网元通信，AUSF通过Nausf接口与CPF中的其他网元通信，AMF通过Namf接口与CPF中的其他网元通信，SMF通过Nsmf接口与CPF中的其他网元通信。
另外，如图2所示的数据网络(Data Network，DN)用于为终端提供服务，例如，提供移动运营商业务、互联网(Internet)服务或第三方服务等。
此外，5G网络架构不仅支持3GPP标准组定义的RAN接入5GC，还支持非3GPP(non-3GPP)接入技术通过non-3GPP交互功能，例如，非3GPP互通功能(Non-3GPP Inter Working Function，N3IWF)、可信非3GPP网关功能(Trusted Non-3GPP Gateway Function，TNGF)、可信WLAN互通功能(Trusted WLAN Interworking Function，TWIF)、或下一代接入网关(Next Generation Packet Data Gateway，NG-PDG)接入5GC。
如图3所示，终端除了可以通过3GPP接入网接入5GC外，终端还可以通过可信非3GPP接入点(Trusted Non-3GPP Access Point，TNAP)和TNGF接入5GC。其中，终端与AMF之间的接口为N1接口，3GPP接入网与AMF之间的接口为N2接口，3GPP接入网与UPF之间的接口为N3接口，AMF与TNGF之间的接口为N2接口，AMF与SMF之间的接口为N11接口，SMF与UPF之间的接口为N4接口，UPF与DN之间的接口为N6接口，UPF与TNGF之间的接口为N3接口，终端与TNAP之间的接口为Yt接口，TNAP与TNGF之间的接口为Ta接口，终端与TNGF之间的接口为NWt接口。
如图4所示，终端还可以通过可信WLAN接入点(Trusted WLAN Access Point，TWAP)和TWIF接入5GC。其中，终端与TWAP之间的接口为Yt接口，TWAP与TWIF之间的接口为Yw接口。
其中，图3和图4的区别在于，当终端不具备通过WLAN构成非接入层(Non-access stratum，NAS)能力时，采用TWAP和TWIF接入5GC，此时TWIF代理终端生成接入5GC需要的NAS消息。可以认为，TWIF是TNGF的一种特殊形式，为方便阐述，下述统一由TNGF代替。
在本申请实施例中，TNAP可包括5G-RG、5G接入网(5G-ANs)和报文数据单元会话锚点(PDU Session Anchor，PSA)，如图5所示，其中，5G-ANs可包括RAN和/或W-5GAN，在图5中可包括多个UPF，该多个UPF可以依次连接，而该多个UPF中与TNGF连接的UPF可作为PSA。5G-RG可通过建立与TNGF或TWIF之间的报文数据单元(Protocol Data Unit，PDU)会话为终端提供与TNGF或TWIF之间的连接。在一些场景中，TNGF或TWIF可作为DN。终端具体可以是3GPP终端(3GPP UE)，3GPP终端也可称为远端设备(remote 3GPP UE)。如图5所示，5G-RG的归属运营商所部署的5GC包括AMF1和SMF1，终端请求的运营商所部署的5GC包括AMF2、SMF2、UPF2。其中，终端与5G-RG之间的接口为Yt接口，终端与AMF2之间的接口为N1接口，5G-RG与AMF1之间的接口为N1接口，5G-AN(s)与AMF1之间的接口为N2接口，5G-AN(s)与PSA之间的接口为N3接口，5G-RG与TNGF或TWIF之间的接口为Ta或Yw接口，PSA与TNGF或TWIF之间的接口为N6接口，SMF1与PSA之间的接口为N4接口，AMF2与TNGF或TWIF之间的接口为N2接口，AMF2与SMF2之间的接口为N11接口，SMF2与UPF2之间的接口为N4接口，UPF2与DN之间的接口为N6接口，TNGF或TWIF与UPF2之间的接口为N3接口。在一些场景中，5G-RG的归属运营商和终端请求的运营商可能不是同一个运营商，因此，需要一种能够让终端通过5G-RG和TNGF接入终端请求的运营商所部署的5GC的方法。为了让终端通过5G-RG和TNGF接入终端请求的运营商所部署的5GC，本申请实施例提供了一种通信方法，下面结合实施例对该通信方法进行详细的描述。
图6为本申请实施例提供的一种通信方法流程图。如图6所示，本实施例所述的通信 方法包括如下步骤：
S601、第一网元接收终端请求的运营商的标识信息。
在本实施例中，第一网元为5G-RG。将终端请求的运营商记为第一运营商，该终端请求的运营商具体可以是该终端的归属运营商，也可以是与该终端归属运营商有漫游协议或者合作关系的运营商。将5G-RG的归属运营商记为第二运营商，第一运营商和第二运营商可以相同，也可以不同。此处以第一运营商和第二运营商不同为例进行示意性说明。
第一运营商的标识信息为r_operator，第二运营商的标识信息为w_operator。由于5G-RG是由第二运营商部署的,因此,5G-RG支持第二运营商。在一些场景下，第二运营商可能会与其他运营商有合作关系，例如，第二运营商可能会与第一运营商和第三运营商有合作关系，因此,5G-RG还可以支持第一运营商和第三运营商。也就是说，5G-RG可能会支持多个运营商。因此，5G-RG可以将自己支持的多个运营商中每个运营商的标识信息广播出去，使得5G-RG覆盖范围内的终端可以接收到广播信息，并根据该广播信息确定5G-RG所支持的运营商。在一些场景中，5G-RG支持的多个运营商中每个运营商的标识信息可构成一个列表，该列表可记为公共陆地移动网络(Public Land Mobile Network，PLMN)列表，该PLMN列表可以理解为5G-RG作为可信非3GPP接入点所支持的可信PLMN列表。在一些场景中，5G-RG支持的运营商可能只有一个，在这种情况下，可信PLMN列表可以只包括一个运营商的标识信息。
当5G-RG覆盖范围内的终端确定出5G-RG所支持的至少一个运营商之后，进一步，确定该至少一个运营商中是否包括该终端请求的运营商，若包括，则终端与5G-RG建立连接，例如，终端与5G-RG建立层2(Layer 2，L2)连接。进一步，终端向5G-RG发送该终端从PLMN列表中选择的运营商的标识信息，该终端选择的运营商的标识信息具体为该终端请求的运营商的标识信息，例如，r_operator。
S602、所述第一网元根据所述终端请求的运营商的标识信息，确定所述第一网元与第二网元之间的会话，所述第二网元是所述终端请求的运营商关联的接入网元。
其中，所述会话用于所述终端通过所述第一网元与所述终端请求的运营商部署的核心网进行通信。
在本实施例中，终端通过5G-RG接入该终端请求的运营商部署的核心网，因此，需要5G-RG能够与该终端请求的运营商关联的网元进行通信，与该终端请求的运营商关联的网元可以是能够接入该终端请求的运营商部署的核心网的接入网元，此处，将该终端请求的运营商关联的接入网元记为第二网元，具体的，第二网元为TNGF。
一种可能的情况，5G-RG可以存储有会话与PLMN列表之间的对应关系，如下表1所示。
表1
会话标识 运营商标识信息
会话1 r_operator
会话2 w_operator
会话3 t_operator
例如，5G-RG支持第一运营商、第二运营商和第三运营商。第一运营商的标识信息为r_operator，第二运营商的标识信息为w_operator，第三运营商的标识信息为t_operator。第一运营商关联的接入网元记为TNGF 1，第二运营商关联的接入网元记为TNGF 2，第三 运营商关联的接入网元记为TNGF 3。其中，会话1可以是5G-RG与TNGF 1之间的会话，会话2可以是5G-RG与TNGF 2之间的会话，会话3可以是5G-RG与TNGF 3之间的会话。其中，TNGF 1、TNGF 2和TNGF 3可以是同一个TNGF，也可以是不同的TNGF。或者，TNGF 1、TNGF 2和TNGF 3部分相同，例如，TNGF 1、TNGF 2和TNGF 3中的两个是同一个TNGF。
例如，当5G-RG接收到该终端请求的运营商的标识信息r_operator时，根据r_operator和如上所述的会话和运营商标识信息之间的对应关系，确定出r_operator对应的会话1，并通过会话1为该终端和该终端请求的运营商部署的核心网提供通信服务。具体的，终端与5G-RG连接，5G-RG与r_operator关联的TNGF 1通过会话1连接，TNGF 1可接入该终端请求的运营商部署的核心网，因此，该终端可以通过5G-RG、会话1接入该终端请求的运营商部署的核心网。
在另一种可能的情况，5G-RG未存储有会话和运营商标识信息之间的对应关系，或者，如表1所示的对应关系中不存在该终端请求的运营商所对应的会话，此时，5G-RG可根据该终端请求的运营商的标识信息，建立5G-RG与TNGF之间的会话，该TNGF是该终端请求的运营商关联的接入网元。进一步，5G-RG通过建立的会话为终端和该终端请求的运营商部署的核心网提供通信服务。另外，在5G-RG建立5G-RG与TNGF之间的会话后，5G-RG还可以建立该会话与该终端请求的运营商的标识信息之间的对应关系。在一些场景中，同一个TNGF可能是多个不同运营商关联的接入网元，例如，TNGF是第一运营商关联的接入网元，也是第二运营商关联的接入网元，当该5G-RG建立5G-RG与TNGF之间的会话后，5G-RG还可以建立该会话与第一运营商的标识信息之间的对应关系，以及该会话与第二运营商的标识信息之间的对应关系。
本实施例所述的会话具体可以是PDU会话。另外，根据TNGF是由终端请求的运营商即第一运营商部署，还是由5G-RG的归属运营商即第二运营商部署，可分为如下几种可能的情况：
一种可能的情况是：TNGF由第二运营商部署，若第二运营商、第一运营商和第三运营商有合作关系时，TNGF可以与第二运营商部署的5GC中的网元进行通信，也可以与第一运营商部署的5GC中的网元进行通信、以及与第三运营商部署的5GC中的网元进行通信。因此，在这种情况下，5G-RG和TNGF之间的PDU会话可以为请求接入第一运营商、第二运营商和第三运营商的终端提供接入相应运营商部署的5GC的服务，也就是说，PDU会话个数与运营商个数之间的比值为1：N，N大于1。在这种情况下，5G-RG建立的会话与PLMN列表之间的对应关系具体为PDU会话与第一运营商、第二运营商和第三运营商的对应关系。
另一种可能的情况是：TNGF由第一运营商部署，则5G-RG和TNGF之间的PDU会话只能为请求接入第一运营商的终端提供接入第一运营商部署的5GC的服务，也就是说，PDU会话个数与运营商个数之间的比值为1：N，N等于1。在这种情况下，5G-RG建立的会话与PLMN列表之间的对应关系具体为PDU会话与第一运营商的对应关系。
本实施例通过第一网元接收终端请求的运营商的标识信息，并根据终端请求的运营商的标识信息，确定第一网元与第二网元之间的会话，该第二网元是该终端请求的运营商关联的接入网元，该第二网元可以接入到该终端请求的运营商所部署的核心网，因此，第一网元通过该会话可以为该终端和该终端请求的运营商所部署的核心网提供通信服务，从而使得该终端通过该第一网元和该会话可以接入该终端请求的运营商所部署的核心网。
下面结合几个具体的实施例对5G-RG与TNGF建立PDU会话、以及5G-RG建立会话与PLMN列表之间的对应关系的具体过程进行介绍。
图7为本申请实施例提供的一种通信方法的信令图。如图7所示，本实施例所述的通信方法涉及到的网元包括：终端、5G-RG、AMF、SMF、UDM、PCF、PSA、TNGF。其中，PCF可记为第三网元，AMF可记为第四网元，SMF可记为第五网元。本实施例所述的通信方法包括如下步骤：
S71、5G-RG向AMF发送注册请求。
S72、AMF向UDM发送用于获取5G-RG的接入签约信息的请求。
具体的，用于获取5G-RG的接入签约信息的请求中包括5G-RG的身份信息、接入类型、位置信息中的一个或多个，UDM根据5G-RG的身份信息、接入类型、位置信息中的一个或多个获取5G-RG的接入签约信息。5G-RG的接入签约信息中包括5G-RG作为可信非3GPP接入点所支持的可信PLMN列表，具体的，该可信PLMN列表可以显示存储在5G-RG的接入签约信息中，或者隐式存储在5G-RG的接入签约信息中。本实施例以该可信PLMN列表显示存储在5G-RG的接入签约信息中为例进行示意性说明。另外，5G-RG的接入签约信息可以预先存储在UDM中，或者，UDM可以从统一数据存储(Unified Data Repository，UDR)中获取5G-RG的接入签约信息。
S73、UDM向AMF发送5G-RG的接入签约信息。
S74、AMF向PCF发送用于获取5G-RG的URSP规则的请求。
具体的，5G-RG的URSP规则中可包括5G-RG支持的至少一个运营商分别关联的接入网元的标识信息。该接入网元的标识信息具体可以是接入网元的数据网络名称(Data Network Name，DNN)。该接入网元具体为TNGF，因此，TNGF的标识信息具体为TNGF的DNN。所谓的TNGF的DNN可以理解为TNGF作为DN时，该DN的数据网络名称。
例如，5G-RG支持第一运营商、第二运营商和第三运营商，相应的，5G-RG的URSP规则中包括第一运营商关联的TNGF 1的DNN、第二运营商关联的TNGF 2的DNN和第三运营商关联的TNGF 3的DNN。
在本实施例中，并不限定5G-RG支持的至少一个运营商分别关联的接入网元的标识信息在该URSP规则中的格式。例如，第一运营商关联的TNGF 1的DNN记为DNN A，第二运营商关联的TNGF 2的DNN记为DNN B，第三运营商关联的TNGF 3的DNN记为DNN C。
例如，针对第一运营商、第二运营商和第三运营商分别关联的TNGF都是TNGF 1的情况，该5G-RG支持的至少一个运营商分别关联的接入网元的标识信息可表示为：
TNGF DNN A.r_operator.w_operator.t_operator。
或者，针对第一运营商、第二运营商和第三运营商分别关联的TNGF都是TNGF 1的情况，该5G-RG支持的至少一个运营商分别关联的接入网元的标识信息还可表示为：
TNGF DNN A.r_operator、TNGF DNN A.w_operator、TNGF DNN A.t_operator。
再例如，针对第一运营商关联的TNGF为TNGF 1，第二运营商和第三运营商分别关联的TNGF均为TNGF 2的情况，该5G-RG支持的至少一个运营商分别关联的接入网元的标识信息可表示为：
TNGF DNN A.r_operator、TNGF DNN B.w_operator.t_operator。
例如，TNGF DNN B.w_operator.t_operator可表示TNGF 2与多个运营商关联，因此，当5G-RG与TNGF 2建立PDU会话后，该PDU会话可以给第二运营商和第三运营商的终端提供接入该终端请求的运营商部署的5GC的服务。TNGF DNN A.r_operator可表示TNGF 1与一个运营商关联，当5G-RG与TNGF 1建立PDU会话后，该PDU会话只能给请求接入第一运营商的终端提供接入该该第一运营商部署的5GC的服务。
S75、PCF向AMF发送URSP规则。
S76、AMF从接入签约信息中获取PLMN列表。
S77、AMF向5G-RG发送PLMN列表和URSP规则。
具体的，AMF可以将PLMN列表和URSP规则同时发送给5G-RG，也可以先后发送给5G-RG。例如，AMF可以通过NAS消息将PLMN列表和URSP规则同时发送给5G-RG，或者先后发送给5G-RG。
可以理解的是，在一些实施例中，URSP规则还可以由5G-RG的归属运营商直接配置在5G-RG本地。也就是说，5G-RG支持的至少一个运营商分别关联的接入网元的标识信息可以存储在5G-RG本地。
S78、5G-RG广播PLMN列表。
具体的，5G-RG可采用接入网络查询协议(Access Network Query Protocol，ANQP)协议将PLMN列表广播出去。
S79、终端选择PLMN。
例如，该终端在5G-RG的覆盖范围内，终端接收到5G-RG广播的PLMN列表后，检测该PLMN列表中是否包括该终端请求的第一运营商的标识信息，该终端请求的第一运营商的标识信息具体可以是该终端请求的第一运营商的标识信息，若包括，则终端从该PLMN列表中选择第一运营商的标识信息即选择PLMN。
S710、终端与5G-RG建立连接。
例如，终端与5G-RG建立L2连接。
S711、终端向5G-RG发送终端选择的PLMN信息。
在终端与5G-RG建立连接后，5G-RG可作为接入点通过扩展认证协议(Extensible Authentication Protocol，EAP)流程请求终端的身份信息，终端在回复的身份信息中包括该终端选择的PLMN信息即第一运营商的标识信息。
S712、5G-RG建立TNGF的标识信息与PLMN列表之间的对应关系。
5G-RG根据S77中接收到的URSP规则建立TNGF的标识信息与PLMN列表之间的对应关系。具体的，5G-RG从该URSP规则中获取5G-RG支持的至少一个运营商分别关联的TNGF的DNN，进一步，建立TNGF的DNN与PLMN列表之间的对应关系。例如，该5G-RG支持的至少一个运营商分别关联的接入网元的标识信息表示为：
TNGF DNN A.r_operator、TNGF DNN B.w_operator.t_operator。
5G-RG建立的TNGF的DNN与PLMN列表之间的对应关系具体如下表2所示：
表2
TNGF的DNN 运营商的标识信息
DNN A r_operator
DNN B w_operator
DNN B t_operator
根据表2可知，第一运营商关联的TNGF为TNGF 1，即TNGF 1与运营商个数是1:1的对应关系，当5G-RG与TNGF 1建立PDU会话后，该PDU会话可能只支持请求接入第一运营商的终端。第二运营商和第三运营商分别关联的TNGF均为TNGF 2，即TNGF 2与运营商个数是1:N，N大于1的对应关系，当5G-RG与TNGF 2建立PDU会话后，该PDU会话可以同时支持请求接入第二运营商的终端和请求接入第三运营商的终端。
S713、5G-RG通过AMF向SMF发送PDU会话建立请求。
5G-RG根据该终端选择的第一运营商的标识信息即r_operator，从表2中查询到r_operator对应的TNGF的DNN为DNN A。5G-RG通过AMF向SMF发送的PDU会话建立请求可包括DNN A，表示5G-RG请求建立与TNGF 1之间的PDU会话。另外，该PDU会话建立请求还可以包括PDU会话类型。具体的，该PDU会话建立请求可以承载在NAS消息中，5G-RG在该NAS消息中可以设置DNN＝DNN A，PDU会话类型为IP类型。
S714、SMF通过AMF向5G-RG发送PDU会话建立响应。
SMF在接收到PDU会话建立请求后，获取5G-RG建立会话所需要的IP地址，并通过AMF向5G-RG发送PDU会话建立响应，该PDU会话建立响应可包括5G-RG建立会话所需要的IP地址。具体的，SMF可通过NAS消息向5G-RG发送PDU会话建立响应。
可以理解的是，5G-RG还可以给每个PDU会话建立一个PDU会话标识，相应的，如上所述的PDU会话建立请求和PDU会话建立响应中还可以包括PDU会话标识。
S715、5G-RG和TNGF建立PDU会话。
5G-RG根据5G-RG建立会话所需要的IP地址与TNGF 1建立PDU会话，在建立PDU会话时，5G-RG建立会话所需要的IP地址可作为源IP地址，TNGF 1的IP地址可作为目的IP地址。至此，5G-RG建立了5G-RG与终端所请求的可信PLMN对应的TNGF 1之间的PDU会话。
S716、5G-RG建立会话与PLMN列表之间的对应关系。
可以理解的是，一个PDU会话可对应一个PDU会话标识，或者，TNGF的IP地址也可用于标识一个PDU会话。因此，当5G-RG建立了5G-RG与TNGF 1之间的PDU会话后，该5G-RG即可建立该PDU会话对应的PDU会话标识(PDU Session ID)与第一运营商的标识信息即r_operator之间的对应关系，如下表3所示，其中，PDU Session 1表示5G-RG与TNGF 1之间的PDU会话的PDU会话标识。或者，5G-RG建立TNGF 1的IP地址与r_operator之间的对应关系，如下表4所示。若5G-RG再次接收到请求接入第一运营商的其他终端的请求，则可通过该PDU会话实现其他终端与第一运营商部署的5GC之间的通信。若5G-RG后续接收到了请求接入第二运营商的终端的请求，由于5G-RG未建立相应的会话与第二运营商之间的对应关系，因此，可重复S713-S716建立相应的会话与第二运营商之间的对应关系。
表3
PDU Session 1 r_operator
表4
TNGF 1的IP地址 r_operator
可以理解的是，如果S79中终端选择的PLMN信息为第二运营商的标识信息w_operator， 则在S713中，5G-RG根据w_operator从表2中查询到w_operator对应的TNGF的DNN为DNN B，并通过AMF向SMF发送的PDU会话建立请求可包括DNN B。在S714中，PDU会话建立响应中包括5G-RG建立会话所需要的IP地址。在S715中，5G-RG和TNGF 2建立PDU会话。由于第二运营商和第三运营商分别关联的TNGF均为TNGF 2，因此，在S716中，5G-RG建立的会话与PLMN列表之间的对应关系可以是如下表5或表6所示的对应关系：
表5
PDU Session 2 w_operator
PDU Session 2 t_operator
表6
TNGF 2的IP地址 w_operator
TNGF 2的IP地址 t_operator
表5中的PDU Session 2表示5G-RG与TNGF 2之间的PDU会话的PDU会话标识。若5G-RG再次接收到请求接入第二运营商或第三运营商的终端的请求，则通过该PDU会话即可实现该终端与该终端请求的运营商部署的5GC之间的通信。
可以理解的是，在S71-S716中，部分步骤的执行顺序是不限定的，例如，S712-S716还可以在S79之前执行，也就是说，5G-RG在接收终端选择的PLMN信息之前，5G-RG可预先建立会话与PLMN列表之间的对应关系，该对应关系具体可以是表3-表6所示的对应关系。当5G-RG接收到终端选择的PLMN信息后，根据终端选择的PLMN信息，从会话与PLMN列表之间的对应关系中确定出该PLMN信息对应的会话，并根据该会话为该终端提供接入该终端请求的运营商部署的5GC的服务。
此外，S76还可以在S73之后执行，S74和S75也可以在S72之前执行。
作为一种可替换方式，在S75中，PCF可以从URSP规则中获取5G-RG支持的至少一个运营商分别关联的接入网元的标识信息,进一步,PCF向AMF发送5G-RG支持的至少一个运营商分别关联的接入网元的标识信息，相应的，S77中AMF向5G-RG发送PLMN列表和5G-RG支持的至少一个运营商分别关联的接入网元的标识信息。
另外，在5G-RG与TNGF建立PDU会话后，该5G-RG还可以通过AMF向SMF发送PDU会话修改请求，该PDU会话修改请求可用于请求修改该PDU会话的QoS。
本实施例通过5G-RG根据终端请求的运营商的标识信息，建立5G-RG与该终端请求的运营商关联的TNGF之间的会话，使得该终端可通过该5G-RG和该TNGF接入该终端请求的运营商部署的5GC，另外，通过5G-RG建立该会话与终端请求的运营商之间的对应关系，可使得请求接入该运营商的终端都可以通过该会话接入该运营商部署的5GC，从而提高了终端与该终端请求的运营商部署的5GC之间的通信效率。
在上述实施例中，该可信PLMN列表显示存储在5G-RG的接入签约信息中，例如可以以签约的可信PLMN列表为索引进行查找，下面结合一个具体的实施例对该可信PLMN列表隐式存储在5G-RG的接入签约信息中的情况进行介绍。例如，该可信PLMN列表隐式存储在5G-RG的接入签约信息中签约的数据网络名称列表中。该签约的数据网络名称列表中5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，进一步的，该TNGF的标识信息包含可信PLMN信息。
图8为本申请实施例提供的另一种通信方法的信令图。如图8所示，本实施例所述的通信方法包括如下步骤：
S81、5G-RG向AMF发送注册请求，该注册请求包括指示信息。
S82、AMF向UDM发送用于获取5G-RG的接入签约信息的请求。
S83、UDM向AMF发送5G-RG的接入签约信息。
S84、AMF向PCF发送用于获取5G-RG的URSP规则的请求。
S85、PCF向AMF发送URSP规则。
S86、AMF根据指示信息从接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，并根据该指示信息从5G-RG支持的至少一个运营商分别关联的TNGF的标识信息中获取PLMN列表。
S87、AMF向5G-RG发送PLMN列表和URSP规则。
S88、5G-RG广播PLMN列表。
S89、终端选择PLMN。
S810、终端与5G-RG建立连接。
S811、终端向5G-RG发送终端选择的PLMN信息。
S812、5G-RG建立TNGF的标识信息与PLMN列表之间的对应关系。
S813、5G-RG通过AMF向SMF发送PDU会话建立请求。
S814、SMF通过AMF向5G-RG发送PDU会话建立响应。
S815、5G-RG和TNGF建立PDU会话。
S816、5G-RG建立会话与PLMN列表之间的对应关系。
本实施例所述的S81-S816相比于如上所述的S71-S716的不同之处在于如下几方面：
一方面，在S81中，5G-RG向AMF发送的注册请求中可携带有指示信息，该指示信息具体可以是无线保真通信请求(wifi_community_request)指示，该wifi_community_request指示用于指示AMF从5G-RG的接入签约信息中获取可信PLMN列表。在本实施例中，该可信PLMN列表隐式存储在5G-RG的接入签约信息中，因此，需要5G-RG向AMF发送指示信息来指示AMF从5G-RG的接入签约信息中获取该可信PLMN列表，并将可信PLMN列表发送给5G-RG。
另一方面，在S82中，AMF向UDM获取5G-RG的接入签约信息时，也可以在用于获取该接入签约信息的请求中携带该wifi_community_request指示。
再一方面，当AMF从UDM接收到5G-RG的接入签约信息之后，例如，在S86中，AMF根据wifi_community_request指示查看5G-RG的接入签约信息，并从5G-RG的接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，进一步，AMF还可以根据该指示信息，从5G-RG支持的至少一个运营商分别关联的TNGF的标识信息中确定出可信PLMN列表。
又一方面，在S87中，AMF还可以生成wifi_community_enabled指示，该wifi_community_enabled指示用于表示AMF对wifi_community_request指示的响应。进一步，AMF将wifi_community_enabled指示、可信PLMN列表和URSP规则一起发送给5G-RG。若S86中，AMF根据wifi_community_request指示未能从5G-RG的接入签约信息中获取到可信PLMN列表，则在S87中，AMF还可以向5G-RG发送wifi_community_disabled指示， 该wifi_community_disabled指示用于指示未找到可信PLMN列表。
本实施例通过5G-RG向AMF发送指示信息，指示AMF从5G-RG的接入签约信息中获取可信PLMN列表，提高了5G-RG获取可信PLMN列表的灵活性。
上面实施例介绍了当可信PLMN列表显示或隐式存储在5G-RG的接入签约信息时，5G-RG获取可信PLMN列表的方法，下面实施例将介绍另一种获取可信PLMN列表的方法。在本实施例中，5G-RG的接入签约信息中还可以包括5G-RG支持的至少一个运营商分别关联的TNGF的标识信息。图9为本申请实施例提供的另一种通信方法的信令图。如图9所示，本实施例所述的通信方法包括如下步骤：
S91、5G-RG向AMF发送注册请求，该注册请求包括指示信息。
S92、AMF向UDM发送用于获取5G-RG的接入签约信息的请求。
S93、UDM向AMF发送5G-RG的接入签约信息。
S94、AMF向PCF发送用于获取5G-RG的URSP规则的请求。
S95、PCF向AMF发送URSP规则。
S96、AMF根据指示信息从接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息。
可以理解的是，在一些场景中，AMF也可以不根据5G-RG的指示信息从接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，也就是说，AMF从UDM接收到5G-RG的接入签约信息后，可以从该5G-RG的接入签约信息中直接获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息。
S97、AMF向5G-RG发送5G-RG支持的至少一个运营商分别关联的TNGF的标识信息。
S98、5G-RG根据5G-RG支持的至少一个运营商分别关联的TNGF的标识信息确定PLMN列表，并广播PLMN列表。
S99、终端选择PLMN。
S910、终端与5G-RG建立连接。
S911、终端向5G-RG发送终端选择的PLMN信息。
S912、5G-RG建立TNGF的标识信息与PLMN列表之间的对应关系。
S913、5G-RG通过AMF向SMF发送PDU会话建立请求。
S914、SMF通过AMF向5G-RG发送PDU会话建立响应。
S915、5G-RG和TNGF建立PDU会话。
S916、5G-RG建立会话与PLMN列表之间的对应关系。
本实施例所述的S91-S916相比于如上所述的S81-S816的不同之处在于如下几方面：
一方面，当AMF从UDM接收到5G-RG的接入签约信息之后，例如，在S96中，AMF根据5G-RG的指示信息，例如，wifi_community_request指示查看5G-RG的接入签约信息，并从5G-RG的接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息。5G-RG支持的至少一个运营商分别关联的TNGF的标识信息具体如上实施例所述，此处不再赘述。
另一方面，在S97中，AMF将5G-RG支持的至少一个运营商分别关联的TNGF的标识信息发送给5G-RG，具体的，AMF可以通过NAS消息将5G-RG支持的至少一个运营商分别关 联的TNGF的标识信息发送给5G-RG。
再一方面，在S98中，5G-RG根据5G-RG支持的至少一个运营商分别关联的TNGF的标识信息确定出PLMN列表，并广播PLMN列表。例如，该5G-RG支持的至少一个运营商分别关联的接入网元的标识信息表示为：
TNGF DNN A.r_operator、TNGF DNN B.w_operator.t_operator。
根据TNGF DNN A.r_operator、TNGF DNN B.w_operator.t_operator，可知，5G-RG支持标识信息为r_operator、w_operator和t_operator的运营商。因此，5G-RG根据TNGF DNN A.r_operator、TNGF DNN B.w_operator.t_operator可确定出PLMN列表，该PLMN列表包括r_operator、w_operator和t_operator。
又一方面，由于在S97中，5G-RG可从AMF接收到5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，因此，在S912中，5G-RG可直接根据5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，建立TNGF标识信息与PLMN列表之间的对应关系，该对应关系的建立过程具体可参照上述实施例所述的方法，此处不再赘述。
可以理解的是，由于在S97中，5G-RG可从AMF接收到5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，因此，在本实施例中，S95中的URSP规则可以不包括5G-RG支持的至少一个运营商分别关联的TNGF的标识信息。或者，也可以没有S94和S95。
此外，在图7或图8中，5G-RG获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息的方法也可以参照图9中5G-RG获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息的方法。
本实施例通过AMF根据5G-RG的指示信息从5G-RG的接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，并将5G-RG支持的至少一个运营商分别关联的TNGF的标识信息发送给5G-RG，5G-RG根据5G-RG支持的至少一个运营商分别关联的TNGF的标识信息确定出PLMN列表，实现了另一种获取PLMN列表的方式，进一步，提高了5G-RG获取PLMN列表的灵活性。
另外，在图8或图9中，5G-RG也可以不向AMF发送指示信息，也就是说，AMF从接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息时可以不根据5G-RG发送的指示信息。同理，AMF从5G-RG支持的至少一个运营商分别关联的TNGF的标识信息中确定出PLMN列表时也可以不根据5G-RG发送的指示信息。
在一些场景中，AMF可以根据指示信息从接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，而从5G-RG支持的至少一个运营商分别关联的TNGF的标识信息中确定出PLMN列表时不根据5G-RG发送的指示信息。
在另一些场景中，AMF从接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息时不根据5G-RG发送的指示信息，而根据指示信息从5G-RG支持的至少一个运营商分别关联的TNGF的标识信息中确定出PLMN列表。
本实施例通过AMF根据5G-RG的指示信息从5G-RG的接入签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的标识信息，并根据5G-RG支持的至少一个运营商分别关联的TNGF的标识信息确定出PLMN列表，进一步，将PLMN列表发送给5G-RG，实现了又一种获取PLMN列表的方式，进一步，提高了5G-RG获取PLMN列表的灵活性。
在上述实施例中，图7、图8、图9是通过注册流程和/或配置更新流程从5G-RG的接入签约信息中获取可信PLMN列表。下面将结合如图10所示的信令图介绍一种通过会话请求流程从5G-RG的会话签约信息中获取可信PLMN列表的方法，该方法属于动态获取可信PLMN列表的方法。另外，当该可信PLMN列表中只有一个运营商的标识信息时，该可信PLMN列表也可记为可信PLMN ID，该可信PLMN ID为该运营商的标识信息。如图10所示，本实施例所述的通信方法包括如下步骤：
S1001、5G-RG在AMF中注册成功。
S1002、5G-RG广播通配的PLMN列表。
在本实施例中，5G-RG广播的PLMN列表可以是通配(wild-card)的PLMN列表。该wild-card PLMN列表表示5G-RG可以为所有的PLMN的远端设备提供通信服务。
S1003、终端选择PLMN。
终端选择该终端请求的运营商的标识信息。
S1004、终端与5G-RG建立连接。
S1005、终端向5G-RG发送终端选择的PLMN信息。
5G-RG可作为接入点通过EAP流程请求终端的身份信息，终端在回复的身份信息中包括PLMN信息，该PLMN信息为该终端请求的运营商的标识信息。在本实施例中，该终端请求的运营商为第一运营商，该终端请求的运营商的标识信息为r_operator。
S1006、5G-RG获取PLMN信息。
5G-RG从终端回复的身份信息中获取该终端请求的运营商的标识信息即r_operator。
S1007、5G-RG通过AMF向SMF发送PDU会话建立请求，该PDU会话建立请求中包括通配的DNN、指示信息和PLMN信息。
S1008、SMF向UDM发送用于获取5G-RG的会话签约信息的请求。
可以理解的是，5G-RG的会话签约信息可以存储在UDM中，或者，UDM可以从UDR中获取5G-RG的会话签约信息。
S1009、UDM向SMF发送5G-RG的会话签约信息。
S1010、SMF获取该PLMN信息关联的TNGF的DNN，以及该DNN对应的PLMN列表。
在本实施例中，5G-RG的会话签约信息可包括5G-RG支持的至少一个运营商分别关联的TNGF的DNN。SMF从UDM接收到5G-RG的会话签约信息后，SMF可根据5G-RG的指示信息，从该5G-RG的会话签约信息中获取5G-RG支持的至少一个运营商分别关联的TNGF的DNN。例如，5G-RG支持的至少一个运营商分别关联的TNGF的DNN表示为：
TNGF DNN A.r_operator.t_operator、TNGF DNN B.w_operator。
进一步，SMF根据该终端请求的运营商的标识信息即r_operator，从5G-RG支持的至少一个运营商分别关联的TNGF的DNN中，确定出r_operator关联的DNN A。由于DNN A不仅与r_operator关联，DNN A还与t_operator关联，因此，可将r_operator和t_operator构成的PLMN列表作为DNN A对应的PLMN列表。在一些场景中，SMF也可以根据5G-RG的指示信息生成DNN A对应的PLMN列表。
S1011、SMF通过AMF向5G-RG发送PDU会话建立响应。
具体的，该PDU会话建立响应可包括5G-RG建立会话所需要的IP地址和DNN A对应 的PLMN列表。可选的，该PDU会话建立响应中还可以包括wifi_community_enabled指示。可选的，该PDU会话建立响应中还可以包括DNN A。
可以理解的是，在一些场景下，DNN A可能只与r_operator关联，此时，SMF可以不生成DNN A对应的PLMN列表，相应的，该PDU会话建立响应中不包括DNN A对应的PLMN列表。
S1012、5G-RG和TNGF建立PDU会话。
例如，5G-RG在接收到PDU会话建立响应后，根据5G-RG建立会话所需要的IP地址和DNN A，建立5G-RG和DNN A对应的TNGF之间的PDU会话。
如果DNN A对应有PLMN列表，则5G-RG和DNN A对应的TNGF之间的PDU会话可以给请求接入该PLMN列表中的多个运营商的终端提供接入相应运行商核心网的服务。
如果DNN A没有相应的PLMN列表，则5G-RG和DNN A对应的TNGF之间的PDU会话只能给请求接入第一运营商的终端提供接入该第一运行商核心网的服务。
S1013、5G-RG建立会话与PLMN列表之间的对应关系。
若5G-RG接收到DNN A对应的PLMN列表，则建立类似于表5或表6所述的对应关系，若5G-RG未接收到DNN A对应的PLMN列表，则建立类似于表3或表4所述的对应关系。5G-RG建立会话与PLMN列表之间的对应关系的过程可参照如上述实施例所述的过程，此处不再赘述。
S1014、5G-RG更新广播列表。
若5G-RG接收到PLMN列表，则将该PLMN列表和wild-card PLMN列表一起广播出去。若5G-RG未接收到PLMN列表，则将r_operator和wild-card PLMN列表一起广播出去。
可以理解的是，如果5G-RG实际能够支持的运营商较少，则5G-RG有可能并不支持该终端请求的运营商。也就是说，在S110中，SMF可能无法获取到该终端请求的运营商关联的TNGF的DNN，在这种情况下，SMF可以向5G-RG发送拒绝请求，5G-RG可以将r_operator存入5G-RG所不支持的PLMN列表，也就是说，5G-RG支持的PLMN列表和5G-RG不支持的PLMN列表分别位于两个不同的列表中。或者，5G-RG支持的PLMN列表和5G-RG不支持的PLMN列表也可以位于同一个列表中，例如，可以在表3、表4、表5或表6所示的对应关系中增加5G-RG不支持的运营商的标识信息，并且5G-RG不支持的运营商的标识信息没有对应的PDU会话标识或TNGF的IP地址。也就是说，当5G-RG支持的PLMN列表和5G-RG不支持的PLMN列表位于同一个列表中时，可以根据运营商的标识信息是否对应有PDU会话标识或TNGF的IP地址，来确定该运营商是否是5G-RG所支持的运营商。例如，若该运营商的标识信息没有对应的PDU会话标识或TNGF的IP地址，则表示该运营商是5G-RG不支持的运营商。若该运营商的标识信息对应有PDU会话标识或TNGF的IP地址，则表示该运营商是5G-RG支持的运营商。
可以理解的是，在图7-图10中，TNGF通过PSA与其他网元通信，同理，其他网元通过PSA与TNGF通信。
本实施例通过5G-RG将终端请求的运营商的标识信息发送给SMF，SMF从5G-RG的会话签约信息中获取该终端请求的运营商关联的TNGF的DNN，并根据该DNN从5G-RG支持的至少一个运营商分别关联的TNGF的DNN中确定出该DNN对应的PLMN列表，进一步，SMF将该DNN和该DNN对应的PLMN列表发送给5G-RG，实现了又一种获取PLMN列表的方式， 进一步，提高了5G-RG获取PLMN列表的灵活性。
