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

Abstract

The invention relates to a state-switching information-processing method, a movable access gateway and a movable terminal. The method comprises the following steps: receiving a state-switching notification message comprising interface use indication information; confirming a switching indication option value according to the interface use indication information; and generating and sending a proxybonding upgrading message comprising the switching indication option value. The movable access gateway switches the states of the movable terminal by the interface use indication information of the movable terminal, has wide range of application and improves the successive access rate of the movable terminal so as to improve the quality of access service provided for users.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, in particular, a state switching information processing method, a mobile access gateway and a mobile terminal. Background technique [0002] Proxy Mobile Internet Protocol version 6 (Proxy Mobile Internet Protocol version 6; hereinafter referred to as: PMIPv6) provides a network-based mobility management protocol. The 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 routing state required for mobile signaling and establishing communication. [0003] figure 1 It is a 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), a mobile access ga...

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
