S201，当第一终端处于基站覆盖范围内且与第二终端存在设备对设备链路关联时，所述第一终端接收所述第二终端发送的业务相关处理信息和/或所述基站发送的业务相关信令消息。其中，第一终端可以为远端UE，第二终端可以为U2NR。
具体实现中，如图1所示，远端UE和U2NR均处于基站覆盖范围内，且第一终端与第二终端之间存在设备对设备链路关联。在此场景中，中继UE可以向其他用户终端广播业务相关处理信息，其中，业务相关处理信息包括中继UE所支持的承载业务类型，或者包括中继UE当前的剩余电量或针对某一特定业务的支持能力。网络侧(但不限于基站)也可以通过广播或者专用信令的方式向远端UE传递业务相关信令消息，所述业务相关信令消息包括中继UE承载业务类型相关的业务门限值，如电量门限值、时延容限值等等。
可选的，如果第一终端处理的业务类型很多，基站可以直接广播与QCI(QoS Class Identifier，标度值)相关的中继UE的选择门限值，其中，标度值用于衡量特定的提供给服务数据流的包转发行为(如丢包率、包延迟预算)。
需要说明的是，远端UE需要中继的数据业务有很多种，每种数据业务对传输特性的传输要求不一样，例如，有些数据业务的对延迟要求低，有些数据业务对延时要求高，而中继UE也存在受限于当前剩余电量或业务处理能力，仅能向远端UE提供部分中继服务，因此，远端UE需要在serving cell服务小区和中继UE之间进行选择。
S202，所述第一终端根据所述业务相关处理信息和/或所述业务相关信令 消息，选择所述第二终端或所述基站进行连接。
具体实现中，所述业务相关处理信息包括承载业务类型，若所述第一终端当前处理的业务为所述第二终端所支持的承载业务类型，选择所述第二终端进行连接；或若所述第一终端当前处理的业务为所述第二终端不支持的承载业务类型，则选择所述基站进行连接。
可选的，所述业务相关处理信息包括所述第二终端的当前剩余电量，所述业务相关信令消息包括电量门限值；可以确定所述第二终端的当前剩余电量是否大于所述电量门限值；若所述第二终端的当前剩余电量大于所述电量门限值，则选择所述第二终端进行连接，若所述第二终端的当前剩余电量不大于所述电量门限值，则选择所述基站进行连接。
可选的，所述业务相关信令消息包括所述第二终端的延时容限值，可以若所述第一终端当前处理业务的时延超过所述延时容限值，则选择所述基站进行连接；或若所述第一终端当前处理业务的时延未超过所述延时容限值，则选择所述第二终端进行连接。
本发明实施例连接选择的方式包括但不局限于上述几种方式，电量门限值、时延容限值等门限值可以由基站配置后发送给远端UE，也可以由远端UE自身设定。
需要说明的是，在选择第二终端进行连接之前，需要确定第一终端与第二终端是否可以匹配，如果第一终端与第二终端不能匹配，第一终端可以选择其他终端进行连接，如果第一终端与第二终端可以匹配，则选择第二终端进行连接。
可选的，在第一终端选择基站连接之后，如果第一终端需要从服务小区切换到连接第二终端，第一终端可以通过第二终端向网络侧发送位置更新消息；在第一终端选择第一终端连接之后，如果第一终端需要从连接第二终端切换到服务小区，第一终端可以通过服务小区向网络侧发送位置更新消息。
在本发明实施例中，当第一终端处于基站覆盖范围内且与第二终端存在设备对设备链路关联时，第一终端首先接收所述第二终端发送的业务相关处理信息和/或所述基站发送的业务相关信令消息；然后根据所述业务相关处理信息和/或所述业务相关信令消息，选择所述第二终端或所述基站进行连接， 从而支持一个终端通过另一个终端接入到网络中，从而提高通信方式的灵活性和业务处理效率。
