Restricted frequency band remote device communication authorization by geographic location
First Claim
1. A method of wireless remote terminal communication within a restricted frequency band, the method comprising:
- geolocating, at the remote terminal, the remote terminal to generate a location specifier corresponding to a geographic location of the remote terminal;
comparing said location specifier with remote terminal authorization information to determine authorization communication conditions for said remote terminal at said geographic location to communicate in the restricted frequency band, wherein said remote terminal authorization information comprises a geographic communication zone map, said geographic communication zone map containing information defining at least one geographic zone, wherein said at least one geographic zone comprises at least one intermediate zone, the step of comparing comprising;
analyzing a position corresponding to said location specifier on said geographic communication zone map to determine in which geographic zone of said at least one geographic zone said geographic location corresponding to said location specifier is situated; and
authorizing communications of said remote terminal in the restricted frequency band in accordance with said authorization communication conditions, wherein said authorization communication conditions are defined for each geographic zone, said authorization communication conditions corresponding to said at least one intermediate zone specifying that said remote terminal is authorized to communicate within said restricted frequency band for a period of time less than a re-authorization timeout period.

Abstract
A system and method are provided for controlling access to a wireless network by a remote terminal in a restricted frequency band in accordance with authorization conditions defined by geographic location. The remote terminal has a geographic self locating capability from which a location specifier is generated. The location specifier is compared to a geographic zone map which has information pertaining to conditions for authorizing communications in the restricted frequency band for various different geographic zones. Depending upon which geographic zone the remote terminal is in or nearby, power level, and time period of communication vary.

4. A remote terminal for wireless communication with a base station within a restricted frequency band, the remote terminal comprising:
-
a geographic auto-location module for generating a location specifier corresponding to a geographic location of the remote terminal; a memory store for storing said location specifier, and for storing remote terminal authorization information, wherein said remote terminal authorization information comprises a geographic communication zone map, said geographic communication zone map containing information defining at least one geographic zone; a geographic comparator for comparing said location specifier with said remote terminal authorization information and to determine authorization communication conditions for said remote terminal at said geographic location to communicate in the restricted frequency band, wherein said authorization communication conditions are defined for each geographic zone, and said geographic comparator in performing said comparing, analyzes a position corresponding to said location specifier on said geographic communication zone map to determine in which geographic zone of said at least one geographic zone said geographic location corresponding to said location specifier is situated; an authorization control module for authorizing communications of said remote terminal in the restricted frequency band in accordance with said authorization communication conditions; and a transmitter controller for controlling communications with said base station in said restricted frequency band according to said authorization communication conditions, wherein said at least one geographic zone comprises at least one intermediate zone, the authorization communication conditions corresponding to said at least one intermediate zone specifying that said remote terminal is authorized to communicate within said restricted frequency band for a period of time less than a re-authorization timeout period. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
