Problems solved by technology

However, the service request is actually for the MBMS service, and the UE does not request the data transmission of the proprietary service
It can be seen that this will cause the wrong operation of SGSN

Embodiment

[0046] 1) Node processing flow of UE

[0047] figure 2 Described is the node processing flow of the UE. Stage 201 indicates that the UE receives a message from the RNC side. In stage 202, it is judged whether the message received by UE is "MBMS Notification", and if so, it turns to 203, otherwise, it turns to 201. In stage 203, the RRC layer of UE submits the service identification and notification reason obtained from the "MBMS Notification" message to the upper layer. If the "RRC connection needs flag" in the message is true, then the signaling connection flag is true. Otherwise, the signaling connection flag is No. The RRC layer of the UE tells the upper layer whether to establish a signaling connection through the signaling connection indication in the primitive. If the RRC of the UE knows that the channel type of the target cell is point-to-point or the target cell does not provide a radio bearer for the MBMS service that the UE is receiving at all, then the RRC of t...

Abstract

The method includes steps: RNC sends message to UE to indicate that UE needs RRC connection; UE sends message to SGSN to indicate that the service is MBMS or dedicated service; based on different service types, SGSN sends different messages to RNC. The invention let SGSN distinguish requests of operations caused by different services. Thus, different operations are adopted for different requests of service. The distinguished operations let SGSN send different signaling to RNC. RNC can make statistics of number of user precisely and can prevent waste of wireless resources.

Description

technical field [0001] The invention relates to the third generation mobile communication system, in particular to a method for SGSN to distinguish MBMS service requests from other service requests. Background technique [0002] MBMS is a new service for which relevant standards are being formulated in the third generation mobile communication system partnership project for standardization. The MBMS service is a one-way point-to-multipoint service (that is, multimedia data broadcast from a single data source is sent to multiple users for reception through network transmission). The biggest feature of this kind of business is that it can effectively utilize wireless resources and network resources. MBMS services are mainly used in wireless communication network systems, such as wideband code division multiple access communication systems and global mobile communication systems. The transmission of business data in MBMS basically goes through several processes: data source t...
