ENABLING A WIRELESS COMMUNICATION DEVICE TO SWITCH FROM ONE LOCAL NETWORK TO A SEPARATE WIDE AREA NETWORK FOR A HIGH PRIORITY MULTICAST GROUP COMMUNICATION

摘要

The disclosure is related to group communications over multimedia broadcast / multicast services (MBMS). An aspect determines whether a number of one or more user devices in an MBMS coverage area participating in a group call is less than a threshold, and delivers a media stream for the group call to a user device of the one or more user devices over a wireless local area network (WLAN) to which the user device is connected based on the number of the one or more user devices in the MBMS coverage area being less than the threshold.
