(A) determines whether or not the voice call is possible using the local area network (step 12; ST-12).

When the user of the wireless terminal A inputs a phone number for a voice call (step 13; ST-13), if the voice call is possible, the local area network using the Bluetooth chip and the web phone algorithm therein are used. Call setup for a voice call with a specific terminal (B) through the mobile communication repeater 40 is made.

If the call is set, a telephone call is made (step 14; ST-14).

If the phone number of the corresponding wireless terminal A is not included in the callable phone number preset in the PC 200, it is determined that the voice call is impossible, and it is determined whether or not an email transmission is possible ( Step 15; ST-15).

In the case of a wireless terminal A capable of sending an e-mail, the wireless terminal A is notified to the wireless terminal A. Thus, when the user writes a short message using the wireless terminal A and inputs an e-mail ID (step 16); ST-16), the corresponding data is transmitted (step 17; ST-17).

On the other hand, the communication system and method using a local area network according to an embodiment of the present invention is not limited only to the above-described embodiment, various modifications are possible within the scope not departing from the technical gist.
