Abstract
Abstract A wireless terminal dynamically maintains location dependent operating parameters while operating in low power-consuming sleep mode. The wireless terminal wakes up periodically to determine its current location. If the current location is within a predetermined distance from a previously stored location, then the wireless terminal stores the previously stored location, along with its associated location dependent operating parameter, in a predetermined memory location within the wireless terminal. If the current location is not within a predetermined distance from a previously stored location, then the wireless terminal generates a new location dependent operating parameter for its current location and stores the current location and new location dependent operating parameter in the predetermined memory location. In various embodiments, the location dependent operating parameter may be, for example, a digital control channel or a mobile switching center identification. In an embodiment in which the location dependent operating parameter is a mobile switching center identification, the wireless terminal may register with an identified mobile switching center when the predetermined memory location is updated.
