Description

technical field

[0001] The invention relates to the technical field of mobile communication, in particular to a mobility management method of a mobile communication system using IP technology. Background technique

[0002] Mobility management technology is a crucial technology in mobile communication system. The mobility management technologies used in mobile communication systems such as GSM, CDMA, and 3G can only be used in circuit-switched systems. At present, the only technology that can enable IP terminals to maintain uninterrupted communication when changing routes during movement is mobile IP technology. It is designed to maintain communication continuity when Internet nodes move. Its important features include: 1. Nodes adopt public IP addresses; 2. Adopt tunnel technology, that is, IP encapsulation of IP. As a common technology in the Internet environment, these features are necessary. However, these characteristics also cause some defects in the mobile IP techno...
