Cooperative scanning-based cell reselection method and system in wireless communication system

摘要

A cell reselection method and system based on a cooperative scanning of the mobile relay station and mobile stations is provided for facilitating cell reselection procedure in a Broadband Wireless Access (BWA) system. The cooperative scanning method for a moving wireless network including a mobile relay station and at least one mobile station according to the present invention includes transmitting, at the moving wireless network, a scanning request with cooperative scanning duration to a serving base station; assigning, when a scanning response, neighbor base stations to the mobile relay station and at least one mobile station; scanning, at the mobile relay station and the at least mobile station, the assigned neighbor base stations; and transmitting scanning results to the serving BS station.
