Apparatus and method for sharing radio spectrum resources among disparate services

摘要

A method for use in mobile station. The method comprises detecting a special code transmitted by first base station, wherein the special code is associated with a border of a restricted area. The method further comprises, in response to detection of the transmitted special code, determining a position of the mobile station and comparing the position of the mobile station to the border of the restricted area. The method also comprises determining whether the mobile station is in the restricted area or a permitted area.

1. For use in a mobile station, a method comprising:
receiving a code transmitted by a first base station, the transmitted code associated with a restricted area; in response to receipt of the transmitted code, determining a position of the mobile station; comparing the position of the mobile station to the restricted area; determining whether the mobile station is in the restricted area or a permitted area; in response to a determination that the mobile station is in the restricted area:
refraining from transmitting using protected channels associated with a protected base station in the restricted area, wherein the restricted area overlaps a coverage area provided by the protected base station; andtransmitting using an alternative channel if the alternative channel is available in the restricted area, wherein the transmitted code identifies the alternative channel; and in response to a determination the mobile station is in the permitted area, accessing the first base station using one of the protected channels, wherein the protected base station is operated by a different service carrier than the first base station, wherein the protected channel is selected from a plurality of radio frequency (RF) channels that are shared by the first base station and the protected base station in order to provide disparate radio services to mobile stations in the permitted and restricted areas, respectively, and wherein the permitted area does not overlap the restricted area.
