US 2004/0176090 A1 · Data throughput improvement in IS2000 networks via effective F-SCH reduced active set pilot switching

Abstract

Systems and methods for improving the performance of wireless telecommunications networks by reducing data communications between a mobile station and a base station. 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 and identifies the strongest signal of a reduced active set 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.

Dependent claims

A method comprising:

monitoring signal strength of signals received from an active set of base stations;
determining a reduced active set of base stations, based on members of said active set of base stations, from which high-speed data communications are received;
detecting a predetermined set of conditions based on the monitored signal strength;
and
initiating a change in said reduced active set of base stations in response to detecting the predetermined set of conditions.
