摘要： 目前互联网在移动性和安全性方面存在缺陷，IP地址同时作为用户的身份标识和位置标识，导致语义过载。该文分析几种典型的基于身份标识和位置标识相分离的名字空间改进方案，比较其对移动性、安全性的支持，提出一种新的基于一体化网络的移动通信机制。

Abstract: There are shortcomings of current Internet on aspects of the mobility and safety, and IP address is overloaded in semantics because it is used to represent both the location and the identity of a user. This paper analyzes several typical namespace improvement solutions that the identity and the position of a user separate mutually currently, compares its mobility, safety, and puts forward a mobile communication mechanism based on the universal network.

Key words: identity, mobile communication, universal network
