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 (Multicast Broadcast Multimedia Service) is an important service defined in the 3GPP Release 6 version. In the future development of the 3rd generation mobile communication network, the MBMS service network will coexist with the existing network of 3G sometime. The two systems will have effects on the system performance of each other. To study the performance influence of Point-to-Point networks on the MBMS service, the simulation model of the TD-MBMS and TD-SCDMA coexisting system was established. Then the results of dynamic system simulation were provided, and the performance influence of the TD-SCDMA service network to the TD-MBMS service was analyzed.
