A LAN or a wireless LAN is connected to the Internet, and the Internet is a digital data communication method using a packet data communication method. Since information transmitted to the other party is transmitted through a plurality of paths, even if a specific path fails There may be a time difference, but there is a certain advantage that it is transmitted, there is an advantage that the network is configured around the world, and the connection fee is relatively inexpensive, and in real time using the packet data communication method of the Internet as described above. The technology of connecting voice with voice level communication has been developed and operated.

A wireless LAN is wirelessly connected to a local area network (LAN). The wireless frequency for connection with the wireless LAN is different from the wireless frequency with which the mobile terminal performs mobile communication.

Therefore, a radio frequency (RF) function unit for wireless LAN connection, a radio frequency (RF) function unit for mobile communication, an analog baseband unit (ABB) for modulating and demodulating the WLAN signal, and a demodulation process for the mobile communication signal Since the analog baseband part (ABB) operates in a different function, each must be provided separately.

The control unit 110 of the process (S110), wirelessly connected to the Internet (INTERNET) through the wireless LAN, and enters the IP (IP) address to the wirelessly connected Internet, so that the connection with the other party, the IP address Set the call for real-time (REAL TIME) voice level communication with the other party connected to (S120).

The wireless LAN unit 100 connected to the other party through the call set in the process S120 is controlled through the path unit 120 which sets the codec 130 and the path PATH under the control of the controller 110. Since it is connected to the codec unit 130, the voice level communication is performed by inputting and outputting a voice level signal with the other party through the speaker 150 and the microphone 160 connected to the codec unit 130 (S130).

Therefore, according to the present invention having the above-described configuration, the codec unit 130 is common in the GSM mobile communication unit 140 and the wireless LAN unit 100 by switching the path unit 120 of the control unit 110. By using it, there is an advantage in simplifying the circuit configuration of the portable terminal, reducing the weight, and reducing the manufacturing cost and time.

According to the present invention, the circuit is simplified because the mobile terminal connects to the wireless LAN, accesses the Internet, establishes a call with the other party using an IP address, communicates with a voice level signal, and uses the mobile communication unit and the codec unit in common. In addition, there is an industrial use effect to reduce the volume and weight.

In addition, since the codec unit is commonly used in the wireless LAN unit and the mobile communication unit, the power consumption is reduced due to the simplified circuit configuration, and the operating time is increased, and the occurrence of failure is reduced, thereby improving reliability.
