Abstract

The invention relates to the mobile communication field, in particular to an agent mobile IPv6 switching technology. The embodiment of the invention discloses an agent mobile IPv6 switching method and the related network entities, and realizes the load control on all mobile access gateways. The agent mobile IPv6 switching method comprises: sending trigger indication for switching mobile nodes from a first mobile access gateway to a second mobile access gateway according to the initiative network triggering and switching strategy; obtaining the context information of the mobile nodes from the first mobile access gateway according to the trigger indication, and establishing a tunnel between the second mobile access gateway and a hometown agent according to the context information; and switching the mobile nodes from the first mobile access gateway to the second mobile access gateway after the tunnel is successfully established. The embodiment of the invention simultaneously discloses a network strategy executing entity, a hometown agent and a mobile access gateway.

Description

technical field

[0001] The invention relates to the field of mobile communication, in particular to a proxy mobile IPv6 switching technology. Background technique

[0002] With the evolution of the network from IPv4 to IPv6, in order to support the mobile IPv6 access of terminals, the Internet Engineering Task Force (IETF) formulated the basic protocol RFC3775 of the Mobile Internet Protocol (MIP), in which Defines the method for the terminal to maintain the current session during the movement. MIPv6 includes three entities: Mobile Node (MobileNode, MN), Home Agent (Home Agent, HA) and Correspondent Node (CN). When the MN is in the home network, it uses a home address (Home of Address, HoA) to communicate with the CN. When the MN moves to a foreign network, the HoA owned by the MN in the home network remains unchanged, and at the same time obtains a temporary IP address allocated by the foreign network, that is, a Care of Address (CoA). The MN sends a registration message...
