具体实施方式
首先指出的是，网络服务可以包括应用层的网络服务和网络特性。A类网络服务需要在接入网络为终端建立数据通道才能接入。B类型网络服务不需要为终端建立数据通道。
A类网络服务可以包括但不限于：IMS语音、本地区域网络(LAN)服务、MBMS、公共告警系统(Public Warning System，PWS)、用户面的位置服务。
B类网络服务可以包括但不限于：电路域回退(CS FallBack，CSFB)，回退到EPS(演进分组系统(Evolved Packet System，EPS)FallBack，EPSFB)，短消息服务(Short Messaging Service，SMS)。
一般来说，只能通过接入提供网络服务的网络来接入所述网络服务。非公众网络(简称为非公网)可能存在多种部署方式，比如1)独立的网络；2)非独立的网络，比如a)是运营商通信网络的一部分；b)是运营商通信网络的切片。
随着非公众网络(简称为非公网)的引入，一个非公网往往只在一个区域范围内提供服务，比如厂区、办公楼、并不是全覆盖。当非公网的签约终端移出了非公网的服务范围，将不能继续访问非公网的网络服务(简称为非公网服务)。如果终端同时签约了公网，可以通过公网接入非公网服务。
对A类网络服务：1)终端可以通过非公网访问公网服务意味着终端可以在非公网上同时建立公网服务的PDU会话和非公网服务的PDU会话。2)终端可以通过公网可以访问非公网服务意味着终端可以在公网上同时建立公网服务的PDU会话和非公网服务的PDU会话。
对B类网络服务：当终端请求第二网络接入第一服务时，第二网络需要验证终端是否允许通过第二网络接入第一服务。
同样，公众网络(简称为公网)虽然是全覆盖，但依然存在一些盲区，如果这些盲区恰巧有非公网的覆盖，且公网签约终端同时签约了非公网，可以通过非公网接入公网服务。
为了支持通过其他网络接入某个网络的网络服务，需解决如下问题：
问题1：并不是所有的非公网服务都可以通过其他网络接入；同样，并不是所有的公网服务都可以通过其他网络接入。比如一些安全性和隐私性比较高的网络服务。但目前还没办法区分哪些是隔离的网络服务。
问题2：如何通过公网接入非公网服务还不清楚。如何通过非公网接入公网服务也还不清楚。目前，a)不清楚哪些公网的公网服务允许通过非公网接入，允许通过哪些非公网接入。b)在某个公网内，不清楚哪些公网服务允许通过非公网接入；哪些公网服务不允许通过非公网接入。c)不清楚哪些非公网的非公网服务允许通过公网接入，允许通过哪些公网接入。d)在某个非公网内，不清楚哪些非公网服务允许通过公网接入；哪些非公网服务不允许通过公网接入。
公网服务和非公网服务的允许区域往往是不同的，目前服务验证PDU会话建立验证的是SMF。随着终端的移动，SMF需要区分公网服务的PDU会话和非公网服务的PDU会话，以决定不同的PDU会话的操作。
问题3：对A类的网络服务，网络服务的相关数据需通过建立的数据通道进行传送。不难理解，通过控制网络服务的数据通道，就能控制网络服务 的接入。目前服务PDU会话建立验证的是SMF。随着终端的移动，SMF需要区分不同允许区域需求的PDU会话，以决定不同的PDU会话的操作。
公网服务的PDU会话和非公网服务的PDU会话的允许区域可以不同；不同的公网服务的PDU会话的允许区域可以不同；不同非公网服务的PDU会话的允许区域可以不同。
问题4：对B类的网络服务，需要终端当前接入网络控制终端是否接入其他网络的服务。当前网络允许的其他网络服务还不清楚。另外，同一网络服务可能可以由多个其他网络提供。终端具体接入的是哪个其他网络的服务还不清楚。
问题5：当非公网时非独立部署时，非公网的服务区域可能不是支持非公网的公网的全部服务范围。当终端移出了非公网的服务范围。而非公网服务不允许通过其他网络接入时，可能要释放和挂起非公网服务的PDU会话；终端在非公网的服务区域也不能请求激活非公网服务的PDU会话。目前，SMF和终端还缺少非公网的服务区域的信息。
可选的，获取可以理解为从配置获得、接收获得、通过请求后接收获得、通过自学习获取、根据未收到的信息推导获取或者是根据接收的信息处理后获得，具体可根据实际需要确定，本公开实施例对此不作限定。比如当未收到设备发送的某个能力指示信息时可推导出该设备不支持该能力。
可选的，发送可以包含广播，系统消息中广播，响应请求后返回。

通过本公开实施例中，可以区分不同的第一服务的不同的服务区域要求，既可以支持通过允许的第二网络接入第一服务，又可以控制不通过不允许第二网络接入第一服务，一方面扩展了网络服务的服务区域，另一方面保障了网络服务的私密和安全性要求。
不难理解，比如第一网络为非公网时，其服务区域是有限的区域(如办公楼，厂区)。第二网络为公网时，其服务范围(也称为覆盖范围)较大。在非公网的服务区域外，可以通过公网或其他非公网接入所述非公网服务。比如第一网络为公网时，也存在一些服务的盲区。如果这些盲区刚好有非公网的覆盖，可以为终端提供允许的公网服务。所以，在第一网络的服务区域之外，可以利用第二网络的覆盖为终端提供允许的第一服务。既可以支持通过非公网接入公网服务，又可以支持通过公网接入非公网服务。另一方面，当第一服务仅允许通过第一网络接入，比如对私密安全性比较高的网络服务，也可以提供控制，避免终端通过不允许的区域接入。

通过本公开实施例中，可以区分不同的第一服务的不同的服务区域要求，既可以支持通过允许的第二网络接入第一服务，又可以控制不通过不允许第二网络接入第一服务，一方面扩展了网络服务的服务区域，另一方面保障了网络服务的私密和安全性要求。
不难理解，比如第一网络为非公网时，其服务区域是有限的区域(如办公楼，厂区)。第二网络为公网时，其服务范围(也称为覆盖范围)较大。在非公网的服务区域外，可以通过公网或其他非公网接入所述非公网服务。比如第一网络为公网时，也存在一些服务的盲区。如果这些盲区刚好有非公网的覆盖，可以为终端提供允许的公网服务。所以，在第一网络的服务区域之外，可以利用第二网络的覆盖为终端提供允许的第一服务。既可以支持通过非公网接入公网服务，又可以支持通过公网接入非公网服务。另一方面，当第一服务仅允许通过第一网络接入，比如对私密安全性比较高的网络服务，也可以提供控制，避免终端通过不允许的区域接入。
