Abstract
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.
Claims20
For use in mobile station, a method comprising:
- detecting a special code transmitted by first base station, the special code associated with a border of a restricted area;
- in response to detection of the transmitted special code, determining a position of the mobile station;
- comparing the position of the mobile station to the border of the restricted area;
- and
- determining whether the mobile station is in the restricted area or a permitted area.
For use in wireless network, a mobile station configured to:
- detect a special code transmitted by first base station, the special code associated with a border of a restricted area;
- in response to detection of the transmitted special code, determine a position of the mobile station;
- compare the position of the mobile station to the border of the restricted area;
- and
- determine whether the mobile station is in the restricted area or a permitted area.
For use in wireless network, a base station configured to transmit a special code to a mobile station, wherein the special code is associated with a border of a restricted area and wherein receipt of the special code by the mobile station is operable to cause the mobile station to determine a position of the mobile station and compare the position of the mobile station to the border of the restricted area to determine whether the mobile station is in the restricted area or a permitted area.
