Method of handling mobility in multimedia broadcast multicast service single frequency network in a wireless communication system and related communication device
First Claim
1. A method of handling mobility in multimedia broadcast multicast service single frequency network (MBSFN) for a user equipment (UE) of a wireless communication system, the method comprising:
- when the UE proceeds with an MBMS service and performs handover from a source cell to a target cell, checking whether a target MBSFN area which the target cell belongs to is the same as a source MBSFN area which the source cell belongs to;
when the target MBSFN area is different from the source MBSFN area, receiving a multicast control channel (MCCH) corresponding to the target MBSFN area;
checking whether the MBMS service is provided in the target MBSFN area; and
when the MBMS service is provided in the target MBSFN area, sending a service join request to a target network of the wireless communication system, for continuing to receive the MBMS service.

Abstract
A method of handling mobility in multimedia broadcast multicast service single frequency network (MBSFN) for a user equipment of a wireless communication system includes when the user equipment proceeds with an MBMS service and performs handover from a source cell to a target cell, checking whether a target MBSFN area which the target cell belongs to is the same as a source MBSFN area which the source cell belongs to, when the target MBSFN area is different from the source MBSFN area, receiving a multicast control channel (MCCH) corresponding to the target MBSFN area, checking whether the MBMS service is provided in the target MBSFN area, and when the MBMS service is provided in the target MBSFN area, sending a service join request to a target network of the wireless communication system, for continuing to receive the MBMS service.

3. A method of handling mobility in multimedia broadcast multicast service single frequency network (MBSFN) for a user equipment (UE) of a wireless communication system, the method comprising:
-
when the UE proceeds with a first MBMS service provided in a first MBSFN area and performs handover from a source cell to a target cell, checking whether the first MBSFN area is included in a plurality of MBSFN areas which the target cell belongs to; when the first MBSFN area is not included in the plurality of MBSFN areas which the target cell belongs to, receiving a plurality of multicast control channels (MCCHs) corresponding to the plurality of MBSFN areas; checking whether the first MBMS service is provided in at least one of the plurality of MBSFN areas; and when the first MBMS service is provided in at least one of the plurality of MBSFN areas, sending a service join request to a target network of the wireless communication system, for continuing to receive the first MBMS service. - View Dependent Claims (4, 5, 6, 7)
