1. A method comprising:
- receiving, by a base station, an access request from an access terminal, wherein the access terminal is physically located within a first distance from the base station, and wherein the first distance is defined by an access search window;
in response to receiving the access request, determining, by the base station, (i) a physical location of the access terminal, and (ii) a specific geographical topology in which the access terminal is physically located, wherein the specific geographical topology contains structure that interferes with signals communicated between the access terminal and the base station;
if the access terminal is physically located within a second distance from the base station, wherein the second distance is associated with the specific geographical topology, accepting, by the base station, the access request; and
if the access terminal is physically located beyond the second distance, rejecting, by the base station, the access request.

Abstract
The present invention provides a method and system for determining whether to accept an access request from an AT. In an embodiment of the invention, a base station receives an access request from an AT that is located within a sector served by the base station. In response to receiving the access request, the base station obtains the physical location of the AT within the sector. The base station then determines whether to accept the access request based on the physical location of the AT within the sector.

7. A system comprising:
-
a base station, wherein the base station includes a processor and data storage, wherein the data storage contains program logic that, upon execution by the processor, causes the base station to; receive an access request from an access terminal, wherein the access terminal is physically located within a first distance from the base station, and wherein the first distance is defined by an access search window; in response to receiving the access request, determine (i) a physical location of the access terminal, and (ii) a specific geographical topology in which the access terminal is physically located, wherein the specific geographical topology contains structure that interferes with signals communicated between the access terminal and the base station; if the access terminal is physically located within a second distance from the base station, wherein the second distance is associated with the specific geographical topology, accept the access request; and if the access terminal is physically located beyond the second distance, reject the access request. - View Dependent Claims (8, 9, 10, 11, 12)
