A MAPPING SERVER IN SUBSCRIBER IDENTIFIER & LOCATOR SEPARATION NETWORK AND A IMPLEMENTING METHOD THEREOF

摘要

Disclosed in the invention are a mapping server in the subscriber identifier & locator separation network and a implementing method thereof. The method comprises the following steps: An Authentication, Authorization and Accounting (AAA) server stores and maintains a mapping relationships of user ID, authentication ID(AID) and locator ID (RID); after receiving the mapping query request which is initiated by the access service router or the internet service node according to the user ID or the AID of the subscriber, the AAA server returns the RID corresponding to the user ID or the AID according to the user ID or the AID in the mapping query request. The invention utilizes the AAA server to realize the main function of the mapping server in the WCDMA-based subscriber identifier & locator separation network. The invention can make full use of the existing AAA server and the messages and flow between the Gateway GPRS Support Node (GGSN) and the AAA server, thus the invention has a preferable economy and feasibility.
