Method, system, customer terminal for mobile IP establishment, and anchor point management apparatus

Abstract

The invention discloses a mobile IP establishing method. The method comprises that a mobile IP client obtains address information of a logical home gateway, wherein, the address information is provided by an anchor management entity, is pre-saved and corresponds to the identification of a data network to which the logical home gateway belongs; mobile IP registration bonding with the logical home gateway is performed by he mobile IP client according to the address information. The invention also discloses a mobile IP establishing system, a mobile IP client and an anchor management device. According to the invention, the mobile IP client only needs to obtain the address information of an anchor management entity, the anchor management entity provides the address information of the logical home gateway which the anchor management entity is bonded with, the mobile IP client only needs to establish an association with the anchor management entity, therefore, association information maintaining workload by the mobile IP client can be reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a mobile IP establishment method, system, client and anchor point management device. Background technique [0002] Mobile IP technology is a mobile node that moves in different networks with a fixed IP address, and ensures that the mobile node realizes business continuity during the moving process. The fixed IP address is called the home IP address of the mobile node, and the home IP address The network to which it belongs is the home network; when the mobile node moves out of the home network and enters a foreign network, the IP address in the foreign network is called the care-of IP address. In the home network, a gateway device is usually set up to maintain the corresponding relationship between the current care-of IP address of the mobile node and the fixed home IP address. The corresponding relationship is notified to the gateway device through the mobil...

Problems solved by technology

[0013] From the above description of the establishment process of the existing mobile IP, it can be seen that before the mobile terminal or MAG in the foreign network accesses multiple data networks in the home network, it must first obtain the IP addresses of all logical home gateways in the home network. The address establishes a security association with the logical home gateway and binds it, and when the terminal or MAG accesses multiple data networks, the mobile terminal or MAG needs to obtain the IP address of each logical home gateway in advance and establish a security association with each logical home gateway , thereby increasing the amount of security association information maintained by mobile terminals or MAGs; when a data network corresponds to multiple logical home gateways, each terminal or MAG accessing the data network may obtain the address of the same logical home gateway, causing the data network Multiple logical home gateways in cannot achieve load sharing
