Methods and systems for adaptive server selection in wireless communications
First Claim
1. A method for wireless communications, comprising:
- determining a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points;
assigning credits to each sector in relation to the forward link quality metric;
changing a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, the non-serving sector being serviced by a non-serving access point different from a serving access point associated with an access terminal; and
transmitting the DSC value.

Abstract
Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.
