The present invention discloses a method, system and device for implementing identity identifier and location separation, to solve the technical problem that the change of the host IP address results in the 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 identifier; the terminal host identity identifier and the terminal location identifier are mapped, the IP address is used for route only, and the host identity is denoted by the host identifier. Consequently, when the host address is changed because of moving or multi-homing and so on, the route is changed, the host identifier still keeps unchanged, and the network application and connection are not interrupted. Therefore, the continuity of the session can be implemented, the mobility, the multi-homing, the dynamic reallocation of IP addresses, and the inter-access among the different network area can be implemented effectively.

Method, system and device for implementing identity identifier and location separation

A method and system for implementing information interaction in a Next Generation Network are disclosed. The method comprises that: a Service Control Function (SCF) sends a location query request message to a ID/Locator Mapping Functional Entity (ILM-FE); the ILM-FE feeds back to the SCF a location query response message, which includes location information and/or information about a characteristic of an IP connection session accessing the service control function. The service control layer utilizes ID/locator separation technology to control the service layer, and uses the characteristic that the user identifier does not change along with the mobile location to provide a rapid transmission location management for a terminal in a moving process. Thus, the service control based on a user identifier is implemented in the NGN, and the continuity of user service is assured when the IP address of the user changes due to the mobility or the multihoming.

Method and system for implementing information interaction in a next generation network

A method and a system for implementing an ID-Locator (ID/LOC) mapping are disclosed. The method includes: after allocating a new IP address to User Equipment (UE), the network side sending an ID/LOC mapping request to an ID-LOC-split Mapping Functional Entity (ILM-FE); and the ILM-FE returning a response with mapping information to the network side according to the received ID/LOC mapping request. The method initiates the ID/LOC mapping based on a network in an ID/locator separation in NGN (IPSPLIT) network, which improves the efficiency of the ID/LOC mapping.
