Problems solved by technology

[0010] The PMIPv6 handover method provided by prior art 2 is actively triggered by the MN, which still cannot solve the problem of MAG load imbalance and maintenance
Prior Art 2 First establish a second tunnel between MAG2 and LMA and then switch MN from MAG1 to MAG2. Before the switchover, forward the message to MAG2 through the tunnel established between MAG1 and MAG2. Since there is no message retransmission, it cannot Ensure the reliability of message transmission between LMA and MN at all times, there may be packet loss problems

Embodiment 1

[0077] Embodiment 1 provides a solution controlled by the LMA and executed by the MAG. Assuming that there is a PS as a network entity on the network side, the management implements the network-side network-triggered handover policy actively, and then the control is triggered by the network-side handover, that is, the PS is the network policy enforcement entity. As a policy proxy (PolicyProxy), the LMA performs handover management for all MNs using it as the home proxy. like Figure 7 As shown, the solution provided by the first embodiment is controlled by LMA and executed by MAG1, including steps:

[0078] S701. The PS sends a trigger instruction for MN handover from MAG1 to MAG2 to the LMA according to the network active trigger handover strategy;

[0079] S702. The LMA initiates the handover of the MN from MAG1 to MAG2 according to the trigger instruction issued by the PS;

[0080]S703. The LMA sends the handover trigger signaling HO Trigger to MAG1, and requests the con...

Embodiment 2

[0101] Embodiment 2 provides a solution controlled and executed by the LMA, and the PS on the network side is a network policy enforcement entity, such as Figure 8 shown, including steps:

[0102] S801. The PS sends a trigger instruction for MN handover from MAG1 to MAG2 to the LMA according to the network active trigger handover policy;

[0103] S802. The LMA initiates the handover of the MN from MAG1 to MAG2 according to the trigger instruction issued by the PS;

[0104] S803. The LMA sends the handover trigger signaling HO Trigger to MAG1, and requests the context information of the subordinate MN from MAG1;

[0105] S804, MAG1 sends the handover request signaling HO Request to the LMA, the handover request signaling includes the context information of the MN, and the signaling may be in the ICMPv6 format or in the context signaling format;

[0106] S805. The LMA receives the handover request signaling HO Request, takes out the context information of the MN, and transfer...

Embodiment 3

[0123] Embodiment 3 provides a solution in which the LMA controls execution and initiates a binding update. The PS on the network side is a network policy enforcement entity, such as Figure 9 shown, including steps:

[0124] S901. The PS sends a trigger instruction for MN handover from MAG1 to MAG2 to the LMA according to the network active trigger handover strategy;

[0125] S902. The LMA initiates the handover of the MN from MAG1 to MAG2 according to the trigger instruction issued by the PS;

[0126] S903. The LMA sends the handover trigger signaling HO Trigger to MAG1, and requests the context information of the subordinate MN from MAG1;

[0127] S904, MAG1 sends the handover request signaling HO Request to the LMA, the signaling includes the context information of the MN, and the signaling may be in the ICMPv6 format or in the context signaling format;

[0128] S905, the LMA takes out the context information of the MN, and initiates a proxy binding update signaling Prox...

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...
