First Claim
1. A mobile station comprising:
- a location determination device identifying a geographic location of the mobile station;
at least one mobile station antenna electrically linked to the location determination device;
a mobile transceiver electrically linked to the at least one antenna, the mobile transceiver configured to transmit and receive mobile communication signals to and from a mobile network system divided into mobile network sectors via the at least one antenna;
a microprocessor electronically linked to the mobile transceiver to control the transmission and reception of the mobile communication signals and communicating with the location determination device; and
a spatial database electronically linked to the microprocessor, and storing data identifying at least one or more geographic positions and geographic regions related to one or more of the mobile network sectors,wherein the microprocessor is configured to;
determine that the mobile station has switched to an idle mode; and
in response to determining that the mobile station has switched to the idle mode and independent of any communication signal of the mobile network system, start a process to compare the geographic location of the mobile station identified by the location determination device with the one or more geographic positions in the spatial database to determine a preferred channel of one of the mobile network sectors and redirect the mobile transceiver to the preferred channel; and
wherein at least one of;
the location determination device;
identifies the geographic location of the mobile station in response to determining that the mobile station has switched to the idle mode and prior to the determining the preferred channel of one of the mobile network sectors, andwherein the identification comprises taking a measurement of the geographic location of the mobile station in response to determining that the mobile station has switched to the idle mode;
orthe microprocessor in redirecting the mobile transceiver;
determines whether the mobile transceiver is currently tuned to the preferred channel supported by the one of the mobile network sectors, andcauses the mobile transceiver to tune to the preferred channel only upon determining that the mobile transceiver is not currently tuned to the preferred channel.

Abstract
A mobile network sector is served via at least an antenna and a mobile network base station transceiver to provide communications with a mobile station. The mobile station includes a mobile station antenna and a location determination device for identifying a geographic location of the mobile station. A transceiver in the mobile station is configured to transmit and receive signals to and from the mobile network base stations, via the mobile station antenna. A microprocessor controls the transmission and reception of the mobile communication signals and communicates with the location determination device. A spatial database identifies geographic positions related to sectors of mobile network base stations. The microprocessor compares the geographical location of the mobile station with the geographic positions of the mobile sectors to determine a preferred mobile network sector and redirect the transceiver to tune to a particular channel supported by the preferred mobile network sector.
