Abstract: In an embodiment, an Internet Protocol (IP) multimedia subsystem (IMS) network that is operated by a single operator receives a request from a user equipment (UE) for registering to a group IMS session. The IMS network determines a location region where the UE is located and identifies a single application server deployed in the location region at which to register UEs that are located in the location region and request registration to the group IMS session. In another embodiment, an application server deployed in a first location region receives a request to register a UE to an IMS session from the IMS network. The application server selectively redirects the registration for the UE either to (i) an application server deployed in a second location region, or (ii) another application server deployed in the first location region.

Abstract translation: 在一个实施例中，由单个运营商操作的因特网协议（IP）多媒体子系统（IMS）网络从用户设备（UE）接收用于注册到组IMS会话的请求。 IMS网络确定UE所在的位置区域，并且识别在位置区域中部署的单个应用服务器，在该位置区域中注册位于该位置区域中的UE，并请求向组IMS会话注册。 在另一个实施例中，部署在第一位置区域中的应用服务器从IMS网络接收向IMS会话注册UE的请求。 应用服务器选择性地将UE的注册重定向到（i）部署在第二位置区域中的应用服务器，或（ii）部署在第一位置区域中的另一应用服务器。
