Efficient multimedia broadcast multicast service continuity methods

摘要

A method is provided for a UE to receive a MBMS. The method includes, when the UE initiates a handover from a first cell that is providing the MBMS, the UE adding a TMGI associated with the MBMS service to a message sent from the UE to an access node in the first cell. The method further comprises the UE receiving information from the access node in the first cell, the information promoting the UE being handed over to a second cell capable of providing the MBMS.

1. A method for operating a user equipment (UE) configured to support a multimedia broadcast multicast service (MBMS), the method comprising:
transmitting, by the UE to an access node in a source cell associated with a group of neighboring cells, a message indicating an MBMS service associated with a multicast-broadcast single-frequency network (MBSFN); and receiving, by the UE from the access node, information promoting a handover of the UE to a target cell,
wherein, when no cell in the group belongs to the MBSFN and exceeds a signal quality threshold, the target cell is the cell in the group with the highest signal quality and the MBMS service is continued in the target cell via point-to-point (p-t-p) transmission, andwherein, when the message comprises an MBMS priority information element (IE) indicating that the MBMS service is not a priority, the target cell is the cell in the group with the highest signal quality.
