BACKGROUND OF THE INVENTION
Technical Field of the Invention The present invention pertains in general to the planning and deployment of a wireless telephone system, and more particularly, to restricting the operation of wireless telephones to delineated geographical locations wherein the geographical location of the wireless telephone is ascertained by the wireless telephone system.
Description of Related Art It is often desirable to prohibit operation of wireless telephones in certain geographical locations.
For example, use of wireless telephones is prohibited in airplanes while on a runway preparing for take-off.
Operation is also prohibited in areas of hospitals where wireless telephone transmissions might interfere with life critical equipment. Furthermore, as the service area of wireless telephone systems grow, such as through the use of satellite based systems providing national coverage, it is desirable to prohibit operation in larger geographical areas such as on military bases.
It has been proposed to equip wireless telephones with locating devices such as Global Positioning System (GPS) receivers which ascertain the geographical location of the wireless telephone. Service is then denied to mobile stations having an ascertained geographical location within a restricted area. Such systems, however, are expensive and the GPS receiver consumes the limited battery power available to wireless telephones. It would be advantageous therefore, to develop a method and apparatus wherein the wireless telephone system itself ascertains the location of the wireless telephone and controls the disabling of telephone operation when the telephone is located in an unauthorized location.
SUMMARY OF THE INVENTION
A wireless telephone system operates to ascertain the geographical location of wireless telephones. In a satellite based wireless telephone system, the wireless telephone system may ascertain the geographical location through a mapping of the position of the wireless telephone in a satellite reference coordinate system, and then converting the position to an earth reference coordinate system. In another embodiment, the wireless telephone system may ascertain the geographical location through triangulation using a plurality of satellites or base stations which monitor wireless telephone signal transmissions. Regardless of the mechanism used for the system to determine location, a comparison is made between the ascertained geographical location and database information pertaining to authorized/un-authorized geographical locations to determine whether telephone operation is authorized. A controller within the wireless telephone system then instructs the wireless telephone to disable itself when the wireless telephone is determined to be located in an unauthorized location and enable itself when located in an authorized location.

DETAILED DESCRIPTION OF EMBODIMENTS
Referring now to Figure 1, there is illustrated a satellite based wireless telephone system 90 including a plurality of the satellites 100A-C, a terrestrial portion 110 of the wireless telephone system 90, and a database 120. Each of the plurality of satellites 100A-C
communicates with the terrestrial portion 110 of the wireless telephone system 90. Although more than one satellite of the plurality of satellites 100A-C may receive transmissions from a wireless telephone 130, typically only one satellite 100A communicates with the wireless telephone 130 at any given time. Communication between the wireless telephone 130 and a public switched telephone network 140 is established via the plurality of satellites 100A-C and the terrestrial portion 110 of the wireless telephone system 90. Also included in the terrestrial portion 110 of the wireless telephone system 90 is a first controller 150 which instructs a second controller 133 within the wireless telephone 130 to disable or enable operation based on the location of the wireless telephone 130.
Several methods are known in the industry for ascertaining the geographical location of a radio transmission source such as the wireless telephone 130.
For example, in a satellite based wireless telephone system a method known as Satellite To Earth (SATTOE) maps a position of the wireless telephone 130 in a satellite reference coordinate system and then converts the position to an earth reference coordinate system. The satellite to earth mapping operation uses a well known rotation transformation matrix, knowledge of a satellite antenna beam footprint, the position of the satellite, and the communication path of the satellite to determine a rough geographical location of the wireless telephone 130. To obtain the location of the wireless telephone 130 with a higher degree of resolution the satellite to earth mapping operation uses additional information such as the results of calculations performed on a Random Access Channel (RACH) and a Dedicated Control Channel (DCCH). Another well known method to determine the geographical location of the wireless telephone 130 in the satellite based wireless telephone system 90 uses two or more satellites 100A-C to triangulate the geographical location of the wireless telephone 130.
Using any known method, the wireless telephone system 90 ascertains the geographical location of the wireless telephone 130 and accesses the database 120 which contains information pertaining to the authorization to operate the wireless telephone 130 in the ascertained geographical location. Based on a comparison of the information contained in the database 120 against the ascertained geographical location, the first controller 150, which is part of the wireless telephone system 90, determines whether operation is authorized. If operation is unauthorized the first controller 150 transmits a command via the satellite 100 instructing the wireless telephone 130 to disable itself. The second controller 133, located in the wireless telephone 130, receives the command via a transceiver 132 and disables the wireless telephone 130.
On the other hand, if operation is authorized the first controller 150, transmits a command via the satellites 100 instructing the wireless telephone 130 to enable itself.
The second controller 133 receives the command via the transceiver 132 and enables the wireless telephone 130.
Referring additionally now to Figure 2, there is illustrated a terrestrial based wireless telephone system 190 including a plurality of base stations 200A-C, a database 120, and a plurality of controllers 250A-C. Each of the plurality of base stations 200A-C communicates with the database 120. Although more than one base station of the plurality of base stations 200A-C may receive transmissions from a wireless telephone 130, typically only one satellite 200A (Figure 1) communicates with the wireless telephone 130 at any given time. Also included in the base stations 200A-C are controllers 250A-C which are capable of instructing the controller 133, located within the wireless telephone 130, to disable and enable operation of the wireless telephone 130.
Several methods are known in the industry for ascertaining the geographical location of the wireless telephone 130 in a terrestrial based wireless telephone communication system. For example, the wireless telephone system can use two or more of the base stations 200A-C
to triangulate the geographical location of the wireless telephone 130. Another approach uses knowledge of which base station 200A is communicating with the wireless telephone 130 and Timing Advance (TA) information used in wireless communication between the base station 200A and the wireless telephone 130 to ascertain a rough estimate of the geographical location.
Using any known method, the wireless telephone system 190 ascertains the geographical location of the wireless telephone 130 and accesses the database 120 containing information pertaining to the authorization to operate the wireless telephone 130 in the ascertained geographical location. Based on a comparison of the information contained in the database 120 against the ascertained geographical location, the controller 250A of the base station 200A serving the wireless telephone 130 determines whether operation is authorized. If operation is unauthorized the controller 250A, located in the base station 200A, transmits a command instructing the wireless telephone 130 to disable itself. The controller 133, located in the wireless telephone 130, receives the command via the transceiver 132 and disables the wireless telephone 130. On the other hand, if operation is authorized, the controller 250A transmits a command instructing the wireless telephone 130 to enable itself.
The controller 133, located in the wireless telephone 130, receives the command via the transceiver 132 and disables the wireless telephone.
Referring additionally now to Figure 3, there is illustrated a flow diagram of a method for implementing the present invention in a wireless telephone system.
During operation of the wireless telephone the wireless telephone system periodically ascertains the geographical location of the wireless telephone (step 300). Any known method of ascertaining the geographical location of the wireless telephone can be used including, but not limited to, mapping the position of the wireless telephone in a satellite reference coordinate system to an earth reference coordinate system, or by triangulation using multiple components of the wireless telephone system.
Once the geographical location is ascertained, the location is compared against database information pertaining to the authorization to operate in the ascertained location (step 305) and a determination is made as to whether operation is authorized (step 310).
If it is determined that operation is unauthorized a controller within the wireless telephone system instructs the wireless telephone to disable itself (step 330). On the other hand, if it is determined that operation is authorized the controller instructs the wireless telephone to continue operation or enable itse,f if disabled (step 340) .
Although embodiments of the method and apparatus of the present invention have been illustrated in the accompanying Drawings and described in the foregoing Detailed Description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the spirit of the invention as set forth and defined by the following claims.
