下面通过具体的实施例十一、实施例十二对上述方法进行介绍:
实施例十一
图11示出了本发明实施例提供的一种通信方法的流程图,如图11所示,所述eNB为第二小区的基站,所述第二基站可以为用户设备的主基站或服务基站,所述方法可以包括:
1101、eNB接收MME发送的第一消息。
其中,所述第一消息包含PLMN信息,所述PLMN信息用于提供有关于PLMN授权状态的信息,所述授权PLMN用于用户设备D2D通信(provides information on the authorization status of PLMN for ProSe services);或者用于指示用户设备被授权在哪些PLMN中进行D2D通信(Indicates in which PLMN the UE is authorized for ProSe services)。

表3
Figure PCTCN2015076386-appb-000003
其中,True表示Indicates the UE is authorized for ProSe Direct Discovery announcement,false表示Indicates the UE is not authorized for ProSe Direct Discovery announcement。因此针对PLMN ID1,状态为ture,表示UE被授权在该PLMN中发送D2Ddiscovry消息。
