Claim:
1. A method for group communications in a mixed casting services wireless communication system comprising: monitoring, by the UE, one or more neighboring cells to determine a potential loss of multicast coverage, and wherein the UE determines the potential loss of multicast coverage based on detecting an absence of transmission of a multicast area identifier by the one or more neighboring cells; detecting, by a user equipment (UE), a loss of multicast coverage; notifying, by the UE, a server over a first unicast service that the UE does not have multicast coverage, wherein the server is configured to provide a desired multicast communication; and requesting, by the UE, that communications related to the desired multicast communication be conducted on a second unicast service using application layer signaling independent of link layer signaling.
