Embodiment Construction

[0039] The present invention consists of two basic modules, "101 a module for scheduling and sending MBMS service data" and "102 a common module", both of which are in the wireless access network. like figure 1 , the data to be sent by each cell is scheduled by the 101 scheduling module, and the scheduling information is reported to the 102 public module, and then the public module calculates the average value of the sending status (sending progress), and feeds it back to the scheduling module. In the next scheduling cycle, the 101 scheduling module will take the received average value into consideration when scheduling the MBMS data of each cell.

[0040] from image 3 It can be seen that MBMS data shares the RLC entity, and the data packets generated by RLC are called RLC PDUs (packet data units). of;

[0041] Moreover, from figure 2 It can be seen that MTCH channels serving different MBMS services can be mapped to the same FACH transmission channel, and multiple MTCH ch...

Abstract

The method comprises: in the first 'discretely transmitting cycle', each cell receives PDU data packet from the shared RLC, and makes numbering for the PDU; according to the schedule information, the 'transmission state' of each cell is reported to the public module; according to the first scheduling information, each cell sends data on the logical channel; according to the received data, the public module figures out the average value of 'transmission state', and feeds back it to each cell; figuring out the different value between the 'transmission state' and the average value; according to the level of the different value and the priority of each MTCH mapped to a same FACH, making the scheduling for the data in next scheduling cycle.

Description

technical field [0001] The invention relates to providing MBMS (Multimedia Broadcast and Multicast Service) services in a WCDMA (Wideband Code Division Multiple Access) mobile communication system, using a balanced method for those cells that use "point-to-multipoint mode" to send data to send business data. 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 (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. [0003] Figure 9 The system structure of MBMS service is described, and the network structure of MBMS service is based on general packet radio service (referred to as GPRS) core network. Below is the right figure 1 description of. [0004] The 901 core network is the data source of the M...
