A METHOD FOR GUARANTEEING ROUTE SET DATA CONSISTENCY IN ULTRA MOBILE BROADBAND SYSTEM

摘要

A method for guaranteeing route set data consistency in Ultra Mobile Broadband (UWB) system is disclosed. In the method, an evolution base station eBS in the Route Set of the terminal AT sends a RouteMap request to the terminal AT for getting RouteMap data; when the AT receives the RouteMap request, it returns a RouteMap message which bears the current last RouteMap data to the eBS; after the eBS receives the RouteMap message, it compares the RouteMap data before the RouteMap request with the RouteMap data after the RouteMap request; if the two data not consistent, the eBS triggers initiatively the AT to broadcast the RouteMap message that bears the current last RouteMap data of the AT again to all the members in the Route Set. By optimizing the process flow for RouteMapRequest message, Route Set data is always consistent between eBSs, so the consistency in the access network for Route Set information of AT is improved and maintained.
