Multiple media broadcasting method in mobile communication system

Abstract

The method can save the bandwidth of the air interface occupied by multi media broadcast. It comprises: in HLR, customizing the dedicated accessing point information for the channel of multi media stream broadcast such that in process of initiating a call, UE informs SGSN and RNC the initiated call is loaded by the dedicated radio access point customized for the channel of multi media stream broadcast; when establishing a radio link bearing the stream media broadcast, using same downlink channel code; when Node B makes multi broadcast, only minimum bandwidth will be occupied.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a multimedia broadcasting method in the mobile communication system. Background technique [0002] With the rapid development of communication technology, people's expectations and requirements for personal communication are getting higher and higher. Therefore, mobile operators need to pay special attention to aspects such as user interface and service quality that directly affect users' experience in using mobile services. Today, with the rapid development of personal communication, the market demand has greatly promoted the progress of mobile communication technology. Especially in the third generation mobile communication system (3rd Generation, referred to as "3G"), each standard system has its own enhancement technology for improving system performance. 3G features such as high bandwidth, multiple services, and high quality have greatly attracted the mobile consumer marke...

AI Technical Summary

Problems solved by technology

3G features such as high bandwidth, multiple services, and high quality have greatly attracted the mobile consumer market. However, if some problems in 3G technology are not resolved, the market expansion will be limited to a certain extent, and the development of mobile operations will be affected.

[0017] In practical application, the above solution has the following problems: currently, the wireless channel used by the wireless access layer to carry the multimedia broadcast service of the upper layer is only a dedicated channel or a shared channel. If a dedicated channel is used to carry multimedia broadcast, it will occupy a large amount of air interface transmission resources and occupy The data transmitted in these resources are the same, and the purpose of sharing the bandwidth cannot be achieved; if the shared channel is used to transmit the multimedia broadcast stream, each terminal still needs to copy its own data, which is actually the same as that of a dedicated channel. There is not much difference in the way of implementation, and there is no fundamental solution to the waste of network bandwidth resources

[0018] The main reason for this situation is that dedicated channels or shared channels are used to carry media stream data for broadcasting, and repeated transmission of stream media wastes network bandwidth.
