Mobile communication apparatus and operating method thereof

1. A mobile communication apparatus, comprising:

a searching module that searches web pages on the Internet for an address corresponding to an inputted partial phone number;

a retrieval module, coupled to the searching module, that retrieves a geographic map according to the address; and

a display module, coupled to the retrieval module, that displays the geographic map,

wherein a scale of the geographic map displayed by the display module is determined at least partially based on the inputted partial phone number.

2. The mobile communication apparatus as claimed in claim 1 , wherein the display module displays the geographic map in a background and a function interface in a foreground.

3. The mobile communication apparatus as claimed in claim 2 , wherein the function interface is an input interface for inputting the phone number.

4. The mobile communication apparatus as claimed in claim 1 , further comprising a geographic database that stores geographic data, wherein the retrieval module retrieves the geographic map from the geographic data according to the address.

5. The mobile communication apparatus as claimed in claim 1 , wherein the searching module searches a plurality of candidate addresses corresponding to the phone number from contexts of one or more of the web pages comprising the phone number, and wherein the searching module further selects one of the candidate address that appears most frequently together with the phone number as the address.

6. The mobile communication apparatus as claimed in claim 1 , wherein the retrieval module obtains the geographic map corresponding to the address from another geographic database on the Internet.

7. The mobile communication apparatus as claimed in claim 1 , wherein the phone number comprises at least two digital numbers.

8. The mobile communication apparatus as claimed in claim 1 , wherein an area covered by the geographic map is determined by the inputted phone number.

10. A method for operating a mobile communication apparatus, comprising:

receiving a partial phone number;

searching web pages on the Internet for an address corresponding to the partial phone number;

retrieving a geographic map according to the address; and

displaying the geographic map such that a scale of the displayed geographic map is at least partially based on the partial phone number.

11. The method as claimed in claim 10 , further comprising displaying a function interface, wherein the geographic map is displayed in a background and a function interface is displayed in a foreground.

12. The method as claimed in claim 11 , wherein the function interface is an input interface for receiving the phone number.

13. The method as claimed in claim 10 , wherein the mobile communication apparatus has a geographic database storing geographic data, and the geographic map is retrieved from the geographic data according to the address.

14. The method as claimed in claim 10 , wherein the step of searching for the address comprises:

searching the phone number from contents of the web pages;

determining, from contexts of the contents of one or more of the web pages comprising the phone number, a plurality of candidate addresses corresponding to the phone number; and

selecting, from the plurality of candidate addresses, a candidate address that appears most frequently together with the phone number as the address corresponding to the phone number.
