MOBILITY METHOD FOR UE IN RRC CONNECTED MODE

摘要

A mobility method for a UE receiving a MBMS service in the state of CELL_FACH or CELL_PCH from one cell to another in RRC connected mode comprising: a step of sending a message of 'Cell Update' to a new cell by the UE; a step of sending a 'MBMS connection request' containing such information as a MBMS Service ID, a UE Identity and a Cell ID to a target cell by a RNC once it receives a message of 'Cell Update' from the UE applying for the MBMS service and if the UE moves between different cells within the same RNC; a step of sending a message of 'MBMS Channel Reconfigure' by the RNC to all UEs within the cell once the type of channel of a cell switches from PTP to PTM due to addition of the UE; a step of sending a message of 'MBMS connection response' to the SRNC by the RNC; a step of sending a message of 'Cell Update Affirm' to the UE by the RNC.
