Title:
METHOD FOR PERFORMING HANDOVER IN BROADBAND WIRELESS ACCESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2005/107377
Kind Code:
A3
Abstract:
A method of entering sleep mode in a mobile subscriber station in performing handover from a first base station (BS 1) to a second base station (BS 2) is disclosed. More specifically, the method includes entering sleep mode in the first base station (BS 1) and transmitting from the first base station (BS 1) sleep mode information in the first base station (BS 1) during handover (S23), while receiving from a second base station (BS 2) sleep mode entry information in the second base station (S24). By providing sleep mode information a mobile subscriber station is enable to effectively re-enter and maintain a sleep mode in a broadband wireless access system after handhover.
