Apparatus and method for dynamically selecting unicast or broadcast resources for a push-to-talk call

摘要

A controller receives a new resource request from a user equipment associated with a first talk group. The new resource request is a request for an assignment of one of MBMS resources and unicast resources for user equipment associated with the first talk group. The controller identifies a second geographical area in which members of the first talk group are located, determines that MBMS resources are available in the second geographical area, and determines whether the first talk group is an MBMS eligible talk group in the second geographical area. In response to determining that the first talk group is an MBMS eligible talk group in the second geographical area, the controller assigns MBMS resources to the first talk group; otherwise, the controller assigns unicast resources to the first talk group.
