Embodiment Construction

[0048] 1) Control the wireless unit controller context update process through the Iur interface

[0049] When the user equipment selects a new cell, the user equipment sends a cell update request to the controlling radio unit controller where the new cell is located, and the message includes the old controlling radio unit controller ID, the old cell ID, the MBMS service ID and the user equipment ID . If the ID of the controlling radio unit controller is the same as the ID of the controlling radio unit controller where the new cell is located, the identification cell selection takes place within the controlling radio unit controller. The controlling radio unit controller will update the MBMS context of the corresponding new cell and the context of the old cell, and delete the corresponding user equipment identifier in the MBMS context of the old cell. If the ID of the controlling radio unit controller is different from the ID of the controlling radio unit controller where the ...

Abstract

User in idle state selects a new subzone, and sends message to controller of controlling wireless unit in the new subzone. If the new subzone belongs to same controller, then the controller deletes corresponding id of user device; if the new subzone does not belongs to same controller, then new controller sends message to old controller to update MBMS context. Next, old controller sends message to new controller to report that updating MBMS context is completed. Finally, new controller sends message to user device to report that updating subzone is completed. The invention solves issue that when user device in idle state leaves the subzone, MBMS context cannot be controlled. Updating context can manage user's mobility effectively, and use wireless resources reasonably.

Description

technical field [0001] The present invention relates to the field of multimedia broadcast / multicast services (referred to as MBMS), and in particular to a method for updating the MBMS context of the control radio unit controller (referred to as RNC) when user equipment in an idle state leaves the old control radio unit controller (referred to as RNC). . Background technique [0002] MBMS is a new service being standardized by the Third Generation Partnership Project (abbreviated 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. In this service, the multimedia data sent from the data source is sent to multiple users through the transmission network. This point-to-multipoint service can save network resources. The MBMS service is mainly used in wireless communication network systems, such as Wideband Code Division Multiple Access (WCDMA for shor...
