METHOD AND SYSTEM FOR REALIZING INFORMATION INTERACTION IN NEXT GENERATION NETWORK

摘要

A method and system for realizing information interaction in next generation network are provided. The method comprises that: the Service Control. Functions (SCF) send a message of location query request to the Identification -Location -Mapping Functional Entity (ILM-FE); the ILM-FE feeds back the response message of location query to the SCF, wherein the message of location query response carries the location information and/or the information about the character of the Internet Protocol (IP) connection session accessing the service control functions. The present scheme makes the service control layer utilize the technique of separating the identification and the location well to control the service layer, and uses the character that the user identification does not change with the mobile location to provide the fast transport location management for a terminal in a moving process. Thus the service controlling based on the user identification is implemented in the Next Generation Network (NGN), and the user service is assured interrupted when the Internet Protocol (IP) address of the user is changed due to the mobility or the multihoming.
