Internet speech communication device of mobile communication terminal and method thereof

The present invention relates to an internet speech communication device of mobile communication terminal and method thereof which comprises: activating the wireless LAN component to set the path of the wireless LAN component and the encode/decode components and setting the call to execute the speech communication operation based on the IP address when the control component of the mobile communication terminal establishes a speech communication operation based on the IP address; setting the path of the wireless LAN component and the encode/decode components and setting the call to execute thespeech communication operation based on the telephone number when establishing a speech communication operation based on the telephone number. According to the invention, a speech communication operation is carried out based on the IP address wherein the encode/decode components are shared with the mobile communication component, as a result, the circuit structure is simplified, the size and the weight of the device are reduced, meanwhile, the power consumption is reduced to advance the running time, and fault factors are also reduced and the product reliability is improved.
