一种新的支持FPLMTS的IN-CS2功能模型

A New IN CS2 Functional Model Supporting FPLMTS

介绍了当前ＩＴＵ建议支持ＦＰＬＭＴＳ（未来公用陆地移动通信系统）的ＩＮＣＳ２功能模型，根据现有和将来网络的特点，指出了这些功能模型的不足．提出了对ＣＳ２功能模型的修改建议，将原来属于ＳＣＦ中的终端鉴权和位置登记从ＳＣＦ中独立出来，形成了独立的功能实体ＬＲＦ和ＴＡＦ．

CS2 functional model supporting FPLMTS in present ITU recommendation was first described. Considering the character of present and future network, we point out the present model's disadvantage and propose an improved CS2 functional model, which separates terminal authentication and location register from SCF and introduces two new functional entities called LRF and TAF. In the end, the advantage and disadvantage of this new model was given.
