Problems solved by technology

[0020] 2. When the MBMS service volume in the pool area is large, figure 2 The default SGSN1 in the network will bear the impact of a large number of MBMS services, which may cause excessive load on the default SGSN1
[0021] 3. Other non-default SGSN resources in a pool area cannot be utilized, and the load balancing of MBMS services cannot be realized

Embodiment Construction

[0034] Such as image 3 As shown, SGSN1, SGSN2...SGSNn constitute a pool area. Among them, the coverage of RNC1 and RNC2 is within the service area of ​​SGSN1, the coverage of RNC3 and RNC4 is within the service area of ​​SGSN2, and the coverage of RNCm-1, RNCm and RNCm+1 is within the service area of ​​SGSNn. There are 4 user equipments in the pool area. Among them, UE1 and UE2 are within the range covered by RNC1 when they are powered on. According to the current user registration principle, these two user equipments are registered on the SGSN1 to which RNC1 belongs; similarly, UE3 is within the range covered by RNC3 when it is powered on. It is registered on SGSN2 to which RNC3 belongs; and user equipment UEm is within the coverage of RNCm when it is turned on, so it is registered on SGSNn to which RNCm belongs. Thereafter, if Figure 4 As shown, UE3 and UEm respectively move from the area covered by RNC3 and RNCn to the area covered by RNC1. Those skilled in the art sh...

Abstract

The invention provides a multi-media broadcast/multicast service method. Its main steps: GGSN sends MBMS service request to SGSN in the whole pool region; each SGSN sends the MBMS service request to RNC; RNC in each region sends the MBMS service request to the user device; each RNC selects one SGSN as í«activation SGSNí», and the rest of SGSN as í«non-activation SGSNí»; each RNC sends the MBMS service request to í«activation SGSNí» and í«non-activation SGSNí», and builds a MBMS service link together with the í«activation SGSNí»; GGSN sends the MBMS data to the í«activation SGSNí»; the í«activation SGSNí» selects corresponding RNC to send the MBMS data to the corresponding user device.

Description

technical field [0001] The present invention relates to a Multimedia Broadcast / Multicast Service (hereinafter referred to as "MBMS") service method in a Wideband Code Division Multiple Access (hereinafter referred to as "WCDMA") communication system, especially It relates to an MBMS service method in a WCDMA communication system using IuFlex interface technology. Background technique [0002] In the previous WCDMA communication system, the radio network controller (Radio Network Control, hereinafter referred to as "RNC") and the serving GPRS support node (Serving GPRS Surport Node, hereinafter referred to as "SGSN") adopt a one-to-many method , that is, one RNC is only connected to one SGSN, and one SGSN can be connected to multiple RNCs. The disadvantage of this networking method is that it is not flexible enough. [0003] With the development and maturity of WCDMA technology, a new connection mode appears between RNC and SGSN, that is, one RNC is only connected with one ...
