METHOD, SYSTEM AND DEVICE FOR IMPLEMENTING IDENTITY IDENTIFIER AND LOCATION SEPARATION

摘要

The present invention discloses a method, a system and a device for implementing the identity identifier and location separation, and solves the technical problem that the change of the host IP address results in connection interrupt of the terminal in the process of moving. By separating and mapping the identity identifier and location identifier, the present invention eliminates the network limitation because of the IP addresses with dual functions of the identity identifier and location identifer; the terminal host identifier and the terminal location identifier are mapped, IP address is used to route only, the host identity is denoted by the host identifier, when the host address is changed because of moving or multi-homing and so on, the route is changed, however the host identifier keeps unchanged, and the network application and connection are not interrupted. The continuity of the phone call can be implemented; the mobility, the multi-homing, the dynamic reallocation of IP addresses, and the mutual accessibility among the different network area can be implemented effectively.
