Problems solved by technology

[0004] Among them, Mobile IPv6 meets the requirement of maintaining Internet reachability during mobile node (Mobile Node; MN for short) handover, but the Mobile IPv6 protocol requires the mobile node to send mobility management signaling to the home agent in the network, and the decisions related to handover are made by the mobile The node is completed, and the burden on the mobile node is heavy, so there is a proxy mobile IPv6

Abstract

The invention provides a mobility management network and a mobile management inter-domain handover method. The network comprises a plurality of PMIPv6 (Proxy Mobile Internet Protocol version 6) domains comprising proxy equipment and a plurality of mobile access gateways; when detecting mobile nodes in other domains, the mobile access gateway sends a first PMIPv6 binding update message to the local proxy equipment and receives a returned first PMIPv6 binding confirmation message, thus establishing a bidirectional tunnel with the local proxy equipment and sending a home network prefix to the mobile nodes; the proxy equipment receives the first PMIPv6 binding update message and returns the first PMIPv6 binding confirmation message; and the first PMIPv6 binding update message sent by the mobile nodes in the local domain is received, and the first PMIPv6 binding confirmation message is returned, thus establishing a bidirectional tunnel with the mobile nodes in the local domain. According to the technical scheme in the invention, the multi-connection technology can be realized under the condition of supporting both local mobility and global mobility.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a mobility management network and a mobility management inter-domain switching method. Background technique [0002] Global System of Mobile communication (GSM for short), General Packet Radio Service (GPRS for short) technology, 3rd-Generation (3G for short) mobile communication technology , Long Term Evolution (LTE for short), WiFi, Worldwide Interoperability for Microwave Access (WiMax for short) and other wireless technologies have provided users with an overlapping , Heterogeneous access environment. The diversification of user needs and the emergence of the user's need to obtain multiple network features at the same time have given birth to the terminal multi-connection technology. Terminal multi-connection technology and the current overlapping and heterogeneous access environment enable users to simultaneously access multiple networks through multiple network interface...
