MBMS(多媒体广播组播业务)是3GPP Release6版本中定义的一项重要的业务类型,它可以在充分利用已有网络的基础上,提供包括手机电视等多媒体业务。在第三代移动通信网络的未来发展中,必然出现MBMS业务网络与3G已有网络共存的情况,两种不同工作模式的业务之间会相互影响。通过对TD-MBMS和TD-SCDMA业务网络共存情况下的系统进行建模和动态系统仿真,分析了在不同环境下TD-SCDMA业务网络对TD-MBMS业务的网络性能影响。
MBMS (Multimedia Broadcast Multicast Service) is an important service type defined in Release 3 of 3GPP. It can provide multimedia services including mobile TV on the basis of making full use of existing networks. In the future development of the third generation mobile communication network, the situation that the MBMS service network coexists with the existing 3G network inevitably arises. Services of the two different working modes will interact with each other. Through TD-SCDMA and TD-SCDMA business network co-existence under the condition of the system modeling and dynamic system simulation, analyzed in different environments TD-SCDMA business network TD-MBMS network performance impact.
