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

[0033] like image 3 As shown, SGSN1, SGSN2...SGSNn constitute a pool area, wherein, the coverage area of ​​RNC1 and RNC2 is within the service area of ​​SGSN1; the coverage area of ​​RNC3 and RNC4 is within the service area of ​​SGSN2; RNCm-1, RNCm and RNCm+ The coverage area of ​​1 is within the service area of ​​SGSNn. There are 4 user equipments in the above pool area. The two user equipments UE1 and UE2 are within the range covered by RNC1 when they are powered on. According to the current user registration principle, these two users 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 the SGSN2 to which RNC3 belongs; and the user equipment UEm is within the coverage of RNCm when it is turned on, so it is registered on SGSNn to which RNCNn belongs.

[0034] Thereafter, user equipment UE3 and UEm move from the original coverage area of ​​RNC2 and RNCn to the coverage area of ​​R...

Abstract

The invention provides a multi-media broadcast / multicast service method. Its main steps: GGSN sends MBMS service request to SGSN registered by all the user devices in the whole pool region; SGSN sends the MBMS service request to RNC; RNC in each region sends the MBMS service request to the user devices; the user device demanding the MBMS service returns the paging response information to RNC; RNCin each region selects one SGSN from multiple SGSNs; and the SGSN sends paging response information to GGSN, the GGSN sends MBMS service data to the SGSN.

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 ...
