METHOD, SYSTEM AND SOFTWARE PRODUCT FOR A MOBILE STATION NOTIFYING AT LEAST ONE BASE STATION OF HAVING BEEN SELECTED FOR SENDING HIGH RATE DOWNLINK DATA BASED ON A PREDETERMINED SET OF CONDITIONS

摘要

One embodiment of the invention is implemented in an IS2000 (cdma2000) network. This network communicates data from a base station to a mobile station over a supplemental forward channel. In order to maintain the best communication channel for data transmissions, the mobile station monitors the signals received from an active set of base stations (410, 420) and identifies the strongest signal of a reduced active set (430) so that the corresponding base station can be selected for data communications. Upon the occurrence of conditions indicating that a new base station within the reduced active set should be selected, the mobile station provides a notification to the base stations in the reduced active set so that further data transmissions will be made by the newly selected base station.
