Abstract

A mobile communication device, and a method of connecting a mobile device to a preferred communication system, are disclosed. The mobile communication device includes a signal sender, a signal receiver, and a processor and memory. The processor and memory include a static table, and are in communication with the signal sender and the signal receiver. The processor and memory match a location of the device directly to at least one preferred system. The mobile communication system includes at least one base station and the at least one mobile communication device. The method includes the step of locating of the mobile communication device, the step of converting the location generated into a position range, the step of matching the position range to at least one preferred SID index for the position range using a lookup table, the step of selecting the preferred SID from a roaming list, wherein the preferred SID is correspondent to the at least one preferred SID index, and the step of connecting the mobile communication device to a channel correspondent to the preferred system indicated by the preferred SID.

6. The mobile communication device of claim 1, wherein the static table comprises at least one roaming list and at least one lookup table.

7. The mobile communication device of claim 6, wherein, upon accessing of a base station by said signal sender, the at least one lookup table matches a known geographic position of the device with respect to the base station with an SID index in the roaming table.

8. The mobile communication device of claim 7, wherein, upon matching of the geographic position with an SID index, the mobile communication device tunes to a preferred channel of the matched SID index.

9. The mobile communication device of claim 8, wherein the device tunes to a preferred channel by a searching of at least two preferred channel sequenced by a preference until a preferred channel is connected to by the mobile communication device.

10. The mobile communication device of claim 1, further comprising a locator.

11. The mobile communication device of claim 10, wherein said locator utilizes GPS.. to locate the mobile communication device

12. The mobile communication device of claim 10, wherein said locator utilizes triangulation to locate the mobile communication device.

13. The mobile communication device of claim 10, further comprising a location converter, wherein said location converter converts a location generated by said locator into a geographic region in the static table.

14. The mobile communication device of claim 13, wherein said location converter comprises a software program resident in said memory.

16. The mobile communication system of claim 15, wherein said mobile communication device further comprises a location converter.
