There are serious information leakage problem in wireless mobile communication,such as mobile terminal identity identification, location infor-mation, etc, since personal data protection in the current communication system is insufficient. This paper analyzes the domestic widespread used 3G wireless communication system at present, points out the existing of information leakage risk in the system, and gives the corresponding solutions. The new scheme can effectively protect the personal informa-tion of mobile terminal, preventing various kinds of attacks caused by information leakage. In addition, this paper also proposes solving strategy to tackle this kind of problem, and provides support for the subsequent protocol design of communication system.
