Embodiment Construction

[0021] (1) The present invention provides the method that solves the mobile UE that is receiving MBMS service in CELL_FACH and CELL_PCH, and this method comprises the following steps:

[0022] a) After the UE receiving MBMS services on CELL_FACH and CELL_PCH moves from one cell to another, it sends a "cell update" message to the new cell. This message adds an information element: MBMS Service ID.

[0023] b) If the UE moves between cells of different radio network controllers (hereinafter referred to as RNC), the serving RNC (hereinafter referred to as SRNC) will send the "cell update" message to the RNC of the target cell after receiving the "cell update" message from the UE that needs to receive MBMS services "MBMS Connection Request" message. The "MBMS Connection Request" message includes: MBMS Service ID, UE Identitv, Cell ID.

[0024] c) If the channel type of the target cell changes from point-to-point (hereinafter referred to as PTP) to point-to-multipoint (hereinafte...

Abstract

A method for moving UE in RRC connection mode, that is, moving the UE in the CELL-FACH or CELL-PCH state and receiving MBMS service to anothe cell, includes such steps as transmitting a 'cell update' message with MBMS service ID from UE to new cell, receiving the messag by RNC, transmitting 'MBMS connection request' message containing MBMS service ID, UE identity and cell ID, or not transmitting if the new cell is in same RNC, RNC transmitting 'MBMS channel relocating' to all UEs in the cell if the UE leads to the channel type change from PTP to PTM, RNC transmitting 'MBMS connection response' to SRNC, and RNC transmitting 'cell updating acknowledge' to the UE.

Description

technical field [0001] The invention relates to a method for solving UE movement in RRC connection mode in a wideband code division multiple access (hereinafter referred to as WCDMA) mobile communication system. Background technique [0002] Multimedia Broadcast and Multicast Service (hereinafter referred to as MBMS) is a new service being standardized by the Third Generation Partnership Project (hereinafter referred to as 3GPP). The MBMS service is a one-way point-to-multipoint service. The biggest feature of this service is that it can effectively utilize wireless resources and network resources. [0003] figure 1 The MBMS system structure is described. The MBMS network structure is based on the general packet radio service (GPRS) core network, and a new network unit is added. Below is the right figure 1 Description of MBMS system structure. [0004] 101 The broadcast and multicast service center (BM-SC for short) is the service control center of the MBMS system. 102 ...
