摘要
移动性管理(MM,MobilityManagement)是层3的一个子层,它主要完成与用户的移动性相关的一些功能。根据业务的分域划分,MM子层被分为支持CS模式的MM实体和支持PS模式的GMM实体。本文通过对GMM一般过程和特殊过程的描述,介绍了TD-SCDMA系统终端GMM实体的功能及其实现过程。
The Mobility Management isone of the sub-layers of the layer 3, which has the function in reference to the mobilityof the subscriber. The MM sub-layer is divided into the MM entity supporting CS mode and the GMM entity supporting PS mode conforming to the principal of service allocation. This paper has interpreted the function and the implement of GMM entity of TD-SCDMA terminal describing the general and special procession of GMM.
