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、PWS(公共告警***(Public Warning System)、用户面的位置服务。
B类网络服务可以包括但不限于：CSFB(CS FallBack)电路域回退，EPS FB(EPS(Evolved Packet System演进分组***)FallBack，回退到EPS)，SMS(Short Messaging Service，短消息服务)。
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协议数据单元(Protocol Data Unit，PDU)会话和非公网服务的PDU会话。2)终端可以通过公网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：终端通过第一网络接入第二网络时，不同终端可能有接入不同的第二网络的需求，第一网络RAN网元如何选择第二网络或代理网元还不清楚。
问题2：当终端与第一网络之间只建立一个RRC连接时，第一网络的RAN网元需要路由两个网络的NAS信息到两个网络，但是NAS(Non-access stratum，非接入层)信息对第一网络RAN网元是透明的，不知道如何路由两个网络的NAS信息。第一网络RAN网元需要给两个网络的数据配置DRB时，终端不清楚配置的DRB是用于传送哪个网络的信息。所以，如何区分第一网络的相关信息(如第二网络的NAS信息和为第二网络接入建立的DRB)和第二网络的相关信息，如何选择第二网络或第一网络和第二网络之间的代理网元是本公开实施例所要解决的问题。
可选的，获取可以理解为从配置获得、接收、通过请求后接收、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，***消息中广播，响应请求后返回。
