State-switching information-processing method, movable access gateway and movable terminal

Abstract

A method for processing handover state information, a mobile access gateway (MAG), and a mobile node (MN) are disclosed. The method includes: receiving a handover state notification message, where the handover state notification message includes interface handover indication information; determining a handover indication option value according to the interface handover indication information; and generating and sending a proxy binding update (PBU) message, where the PBU message includes the handover indication option value. With the present invention, a MAG can obtain the handover state information of an MN through the interface handover indication information of the MN. The application scope is wide, and the access success probability is increased; therefore, the access quality of service (QoS) provided for the user is improved.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication technology, in particular to a state switching information processing method, a mobile access gateway and a mobile terminal. Background technique [0002] Proxy Mobile Internet Protocol version 6 (hereinafter referred to as PMIPv6) provides a network-based mobility management protocol. A mobile node (Mobile Node; hereinafter referred to as: MN) does not need to participate in any mobility management signaling in the PMIPv6 network. The mobile entity in the network tracks the movement of the MN, and initializes the mobile signaling and establishes the routing state required for communication. [0003] figure 1 Schematic diagram of the existing PMIPv6 network system structure, such as figure 1 As shown, the network system includes a local mobility anchor (Local Mobility Anchor; hereinafter referred to as: LMA), mobile access gateway (Mobile Access Gateway; hereinafter referred to as: ...

AI Technical Summary

Problems solved by technology

[0005] The inventor found in the process of implementing the present invention that: when obtaining the handover state of the MN through the context transmission between MAGs, the context interface between the MAGs is needed so that the new MAG can obtain relevant information such as handover instructions from the old MAG, but in some Scenarios may not be able to proceed as scheduled, such as heterogeneous network handover, there is no security association between MAGs, etc.; while using the AAA architecture to obtain the handover status of the MN, it cannot be used in scenarios where AAA does not save interface-related information or does not use the AAA structure

Existing technical solutions have a small application range, certain limitations, and poor service quality
