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

Embodiment Construction

[0027] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0028] figure 2 It is a flowchart of Embodiment 1 of a method for processing state switching information of the present invention. Such as figure 2 As shown, the state switching information processing method includes the following steps:

[0029] Step 200: Receive a state switching notification message, where the state switching notification message includes interface use indication information;

[0030] In the PMIPv6 network, when the interface of the mobile terminal accessing the network is switched, the switching status of the interface needs to be sent to the mobile access gateway, and the mobile access gateway receives the status switching notification message sent by the mobile terminal. In the status switching notification message It may include interface use indication information of the mobile terminal, where the interface ...

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: ...
