Embodiment Construction

[0045] In order to solve the problem that the MBMS channel type is converted when the UE moves to a cell under the DRNC and the SRNC does not relocate, the present invention proposes three methods in total.

[0046] Method 1 utilizes the existing cell switching process, and achieves MBMS channel switching by modifying existing messages. This process can be done with four messages. In addition, by modifying the existing message, the RNC can correctly count the number of MBMS service users when the users move.

[0047] The second method does not change the existing message for implementing cell switching, and completes the MBMS channel switching through two newly added messages. This method does not affect existing switchover procedures. And the process of converting the dedicated channel to the common channel and the process of converting the common channel to the dedicated channel can be realized by the same process.

[0048] Method 3 does not change the existing message fo...

Abstract

The method can deal with the following situation. It can solve MBMS channel conversion course under the situation that SRNC is not reset for positioning, UE is receiving MBMS service and MBMS channeltype or parameter is changing when UE is moved to cell below DRNC. It can solve MBMS channel type conversion course caused by moving of the other user or new service entering under situation that UE is not moved and there is service going on through connecting to SRNC by DRNC and it can solve problem of DRNC counting the user under the situation that SRNC is not reset for positioning when UE is moved to cell below DRNC.

Description

technical field [0001] The invention relates to multimedia broadcasting and multicasting services, in particular to a point-to-point channel and point-to-multipoint channel conversion method for multimedia broadcasting and multicasting services. Background technique [0002] Multimedia broadcast and multicast service (hereinafter referred to as MBMS) is a new point-to-multipoint service in the third generation mobile communication. The available channel types of MBMS can be point-to-point channels or point-to-multipoint channels according to the number of service users. Under the existing point-to-point service mechanism, when a user moves to a new cell, the channel used is switched from the source cell to the target cell. Existing channel switching is based on point-to-point channels, and channel characteristics do not change. Under MBMS business, changing the cell may cause the change of the channel characteristic. [0003] In order to better describe this patent, Figu...
