Abstract

A wireless communication device and method for automatically selecting a band and mode is provided. Utilizing the global positioning system to obtain the position of the wireless device for simplifying the process of searching service networks and reducing power consumption. Furthermore, a method for a wireless communication device to automatically select a band and mode is also provided.

Claims

1. A wireless communication device for automatically selecting a communication band and mode, comprising:

a Global Positioning System (GPS) module for obtaining a position of said wireless communication device;

a memory module having a database, said database storing a plurality of regions, each with a corresponding communication band and mode;

a processing module in connection with said GPS module and said memory module, said processing module utilizing said position and said database to select a band and a communication mode used in said position; and

a mobile telecommunication module in connection with said processing module, said mobile telecommunication module utilizing said selected communication band and mode to send a registration signal.

2. The wireless communication device of claim 1, wherein said wireless communication device comprises a multi-band, multi-mode, or multi-band multi-mode wireless communication device.

3. The wireless communication device of claim 1, wherein said database comprises a function of updating stored contents in said database.

4. The wireless communication device of claim 1, wherein said memory module further comprises a function of recording said position in said memory module.

5. A method for a wireless communication device automatically selecting a communication band and mode, said wireless communication device supporting a GPS system and having a database, said method comprising the following steps:

(a) obtaining a position of said wireless communication device from said GPS system;

(b) querying said database based on said position to select a communication band and mode used in said position;

(c) utilizing said selected communication band and mode to send a registration signal of said wireless communication device.

6. The method of claim 5, wherein said steps of (a) to (c) are executed when said wireless communication device is powered on.

7. The method of claim 5, wherein said database comprises a function of updating stored contents in said database.

8. The method of claim 5, wherein said step of querying said database further comprises the step of referring to previous positions of said wireless communication device.
