Abstract:
A user equipment (UE) provides service continuity when the UE is about to move out of coverage of a Multimedia Broadcast Multicast Service (MBMS). The UE: receives MBMS data via an MBMS bearer; detects that the UE is suffering from a bad MBMS bearer condition; informs a server of the bad MBMS conditions to initiate switching to unicast; wherein, if there is downlink data to deliver during switching, the UE begins to receive the downlink data via unicast and to continues to receive downlink data via the MBMS bearer until the switching to the unicast bearer is complete. The UE is configured to determine a quality of the MBMS bearer relative to a threshold, which is dependent on service type, for indicating that the MBMS bearer quality is not acceptable. When the threshold is reached, the UE sends a message to the server.
