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 ...
