Problems solved by technology

[0013] The SRNS migration operation can realize the synchronization between the UE and the DRNC when performing cell updates between cells of different RNCs, but when the UE is transmitting multimedia services, the SRNC cannot transfer the UE’s cell multimedia service application layer context to the DRNC , so the DRNC cannot complete the function of rebuilding the UE service context
In this way, when the UE enters the service area of ​​another RNC from the service area of ​​one RNC, the network side cannot connect the multimedia service of the UE's cell from the SRNC to the DRNC, resulting in interruption of multimedia service data transmission

Embodiment Construction

[0032] The present invention is an SRNS migration method based on mobile network multicast service data. When the UE enters the DRNC service area from the SRNC service area, it sends a cell update request to the network side, and the network side performs the SRNS relocation operation. During the SRNS relocation operation, the UE multicast service establishment process context is sent to the DRNC to connect the multicast service from the SRNC to the DRNC.

[0033] See Figure 4 As shown, a method for implementing multicast service data based on a mobile network, the method proposes to move the function of the streaming media server down to the RAN side, and establish a multimedia connection by setting up a multicast proxy module (MA) on the RAN side Multi-media playback technology to achieve point-to-multipoint data transmission.

[0034] Among them, the multicast agent module is composed of a control agent (CA) module and a data agent (DA) module. The CA module acts as a proxy for...

Abstract

The present invention provides mobile network multicasting transaction data based SRNS migration method. Said method includes user equipment UE entering DRNC service area from SRNC service area, transmitting cell updating request to network side, network side making SRNS relocation operation, SRNC transmitting user equipment multicasting service establishing process context to DRNC, for switching multicasting service from SRNC to DRNC. The present invention realizes uninterrupted service from SRNC entering DRNC, through increasing cell in radio resource control package cell mode without modifying net element.

Description

Technical field [0001] The present invention relates to a Serving Radio Network Subsystem (SRNS) in a wideband code division multiple access system (WCDMA) from a serving radio network controller (Serving Radio Network Controller, SRNC) to a drift radio network controller (Drift). RadioNetwork Controller (DRNC) migration method, especially refers to a SRNS migration method of multicast service data. Background technique [0002] With the improvement of functions and performance, mobile phones are no longer just tools for making calls. Its functions in multimedia messaging, video-on-demand, videophone, mobile TV, etc. can already be supported and have certain applications. According to the information processing capabilities of current mobile phones, the effect of watching streaming media on mobile phones can be satisfied. With the bandwidth provided by WCDMA for packet services, it can be said that multimedia playback on WCDMA is mature. [0003] At present, the existing streamin...
