Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] The present invention proposes an implicit method for selecting a mobility management mode similar to that in WiMax for IPv6. But unlike WiMax, the present invention supports both preferably terminal-based Mobile IPv6, ie standard MIPv6, and network-based Mobile IPv6, ie Proxy Mobile IPv6.

[0041] The present invention makes the following provisions on the wireless access network:

[0042] ① Set the A flag of the IP address prefix (Prefix) in the route advertisement message broadcast by the wireless access network to 0, and set the M / O flag of the route advertisement message to 1, thereby notifying the mobile terminal to configure through DHCPv6 IP address.

[0043] ② When the DHCPv6 discovery message received by the wireless access network contains a home network ID (Home Network ID), the wireless access network considers that the mobile terminal h...

Abstract

The invention provides a selection method of mobile management mode in wireless network, applied in a process of accessing a mobile terminal into configuration IPv6 address of the wireless network. Method of the invention selects an appropriate mobile management mode for the access terminal by integrally considering mobile management mode of the mobile terminal, signing mobile management mode of the mobile terminal, mobile management mode and strategy information of the access network, and mobile management mode of home proxy during the process of requesting to access into the access network by the mobile terminal. Method of the invention improves business continuing capability of mobile terminal when switching types crossing networks, synchronously improves access capability of access network when access terminal is accessing.

Description

technical field [0001] The invention relates to a mobile management mode in a wireless network, in particular to a selection method for a mobile management mode in a wireless network. Background technique [0002] Mobile IP (MIP, Mobile IP) is a widely accepted mobility management protocol, which can keep the IP connection uninterrupted when the mobile terminal (MN, Mobile Node) moves between different networks. In Mobile IP, a mobile terminal keeps its home IP address (HoA, Home of Address) unchanged. When the access point of the mobile terminal changes, the mobile terminal notifies its home network (Home Network) of the change through a binding update (BindingUpdate, applicable to MIPv6) or a registration request message (RRQ, Register Request, applicable to MIPv4). Home Agent (HA, Home Agent) of the mobile terminal, so that the data sent to the mobile terminal can be correctly routed to the new access point. [0003] Mobile IP technology requires mobile terminals to sup...
