Embodiment Construction

[0035] The logical structure of the network on which the inventive method relies is as follows: figure 1 shown. The whole network is composed of two layers of wide area network 11 and local area network 12 . The local area network 12 is connected to the wide area network 11 through its internal proxy server. A plurality of local area networks 12 can be connected under one wide area network 11 .

[0036] In the wide area network 11, the IP address of the wide area network is used. If the WAN is a public network, the public IP address is used. If the WAN is a private network, the private IP address in the private network is used.

[0037] Devices related to mobility management in the LAN in the network on which the inventive method relies, such as figure 2 shown, it is right figure 1 A detailed description of the local area network. The local area network is composed of a local area network device 21 , a proxy server 22 , a base station 23 and a wireless terminal 24 . T...

Abstract

This invention refers to communication technology field, especially a mobile management method for mobile communication system adopting IP technology, which contains 1, broadcasting mark message, 2, judging whether it crosses over the LAN, 3, quick IP address distribution, 4, redirection. Said invention overcomes the shortage in mobile IP technology

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...
