CONTROL SCHEMES FOR DETERMINING ACCESS TERMINAL LOCATION
First Claim
1. An apparatus for communication, comprising:
- a processing system configured to determine that at least one location of an access terminal is to be estimated; and
a transmitter configured to send a message to adjust at least one active set parameter for the access terminal as a result of the determination.

Abstract
A location of an access terminal is estimated based on signals received by the access terminal. The manner in which a femto cell transmits signals and/or the manner in which the access terminal monitors for signals may be controlled in some cases to facilitate the reception of signals at the access terminal during a location determination operation. In some embodiments, the number of femto cells for which the access terminal monitors for signals may be controlled by controlling the manner in which the access terminal maintains its active set. In some embodiments, in the event a given femto cell is interfering with the ability of an access terminal to receive signals from other femto cells, that femto cell may be instructed to temporarily stop transmissions (e.g., on the traffic channel and/or a beacon channel).
