CONTROLLING ACCESS POINT FUNCTIONALITY
First Claim
1. A method of communication, comprising:
- receiving, at an access terminal, at least one signal from at least one access point;
deriving phase information from the at least one signal;
determining a location condition of the access terminal relative to another access point by comparing the derived phase information with phase information maintained at the access terminal; and
sending a message to a network management node to control wireless transmission at the another access point based on the determined location condition.

Abstract
Wireless transmission and/or other functions of an access point (e.g., a femto access point) are controlled based on whether an access terminal is in the vicinity of the access point. For example, wireless transmission may be enabled or disabled based on whether an authorized access terminal is inside or outside a perimeter associated with the access point. An access terminal may send a message to control wireless transmission and/or other functions of the access point based on signals (e.g., pilot signals) the access terminal receives from other access points. For example, the access terminal may determine whether it is inside or outside the perimeter based on comparison of phase information derived from received macro pilot signals with phase information maintained at the access terminal.
