摘　　要：为宽带码多分址通讯系统的功能在关键技术的研究方面与国际接轨,设计了一种有效解决实际问题的功能模块.随着陆地移动通信系统以语音业务为主的第二代系统发展到全面提供移动多媒体业务为主的宽带码多分址通讯系统,相应的网络结构也以电路交换为主发展到分组交换为主.业务需求以及网络结构的变化导致移动性管理模式的变化.为此深入分析了功能集中的MM模块和宽带码多分址通讯系统的主要功能模块,并做了详细地设计,对移动管理过程中的异常情况进行处理,给出了模块图及位置更新流程图.In order to be in line with the international standards in the field of key technology of broadband code division multiple sub-site communication systems, an effective functional module to solve practical problems is designed. With the voice-based second-generation system of land mobile communication systems being developed into broadband code division multiple sub-site communication systems, mobile multimedia service is widely available. Correspondingly, the conversion from circuit-switching to packet-based switching of network structure is also accomplished. Business needs and network structure changes lead to transformation of mobility management patterns. After in-depth analysis and detailed design of the function concentrated MM module and the main function module of wideband code division multiple sub-site communication system, the paper takes abnormal situations in the mobile management process and makes block diagram and flow chart of updated location.
