Multimedia broadcast multicast service scheduling method and system

Abstract

The invention discloses a method and a system for dispatching multimedia broadcast multicast services, wherein, the method comprises the following steps: (S302) MSCH configuration information is set by a radio network controller according to a transmission time interval of MSCH, MBMS service dispatching information is set according to the transmission time interval of the MTCH, the MSCH configuration information is transmitted to all user equipment in a cell through MCCH channels, and the MBMS service dispatching information is transmitted to all the user equipment in the cell through MSCH channels at the starting time of a dispatching period; and (S304) analysis is carried out by the user equipment after receiving the MSCH configuration information and the MBMS service dispatching information on the MSCH channels is read at the starting point of the dispatching period, and the analysis is carried out by the user equipment after receiving the MBMS service dispatching information and data on MTCH channels is read according to analyzed service dispatching information. By applying the method and the system of the invention, the electric power consumption of UE can be furthest saved, the completely receiving of the service data by the UE can be ensured and that the transmission of the MBMS service dispatching information on different MSCH channels is furthest staggered can ensured.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a multimedia broadcast multicast service scheduling method and system. Background technique [0002] Multimedia Broadcast / Multicast Service (MBMS for short) is a technology for sharing network resources and transmitting data from one data source to multiple targets. In order to effectively utilize mobile network resources, the Third Generation Partnership Project (3GPP) proposed the MBMS service in R6, that is, a point-to-multiple service that provides a data source to send data to multiple users in the mobile network. Point business, in order to realize network resource sharing, improve the utilization rate of network resource (especially the precious air interface resource). MBMS can not only realize plain text low-rate message multicast and broadcast, but also realize multicast and broadcast of high-speed multimedia services, and provide a variety of rich vid...

AI Technical Summary

Problems solved by technology

[0018] 1. The setting of MSCH_OFF does not consider the TTI of MSCH;

[0019] 2. The setting of Start does not consider the TTI of MTCH;

[0020] 3. The setting of Duration does not consider the TTI of MTCH;

[0021] The above problems will lead to the inability to completely stagger the transmission of MSCH scheduling information, insufficient power saving effect of UE, and even data errors due to incomplete received data
