There may be a plurality of embodiments of the present invention. Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings. This embodiment allows for a better understanding of the objects, features and advantages of the present invention.

1 is a schematic configuration diagram of a mobile communication system to which a personal mobile terminal device according to the present invention is applied, while User B (1) carries a personal mobile terminal device (100,200) according to the present invention. In addition to the transmission of the voice signal, the MISP (Mobile Internet Service Provider) 3 transmits the data signal, and the mobile communication switching center 4 transmits the voice signal by the user A (2) and the data signal by the MISP (3). The case of collecting the voice and data signals simultaneously to the user B 1 is illustrated.

The personal mobile terminal device according to the present invention is capable of receiving a data signal from the main terminal 100 in both the main terminal 100 for communicating both voice and data signals with the mobile communication switching center 4 and outputting the same through the display means. It consists of an auxiliary terminal 200.

As shown in Fig. 2, the main terminal 100 transmits a voice signal input through the microphone 101 and a wireless communication circuit 110 for both communicating voice and data signals with the mobile communication switching center 4; The voice processing unit 120 performs voice processing for outputting the voice signal received through the wireless communication circuit 110 to the speaker 102, and the data signal received through the wireless communication circuit 110 to the outside. A display unit 130, an input unit 140 for generating a key signal input through the keypad, a data transmitter 150 for wirelessly transmitting the received data signal, and a key signal or microphone input through the input unit 140 Control unit 160 that manages the wireless call function and data transmission function according to the voice signal input through the 101, and the power supply unit 170 that provides the power supplied from the battery as the operating power of each circuit part It is composed.

The wireless communication circuit 110 includes a receiver 111 that receives a high frequency signal induced by an antenna, a decoder 112 that decodes the signal received by the receiver 111 and outputs data, and an encoder that encodes transmission data ( 113, a transmitter 114 for modulating and transmitting the encoded signal into a high frequency signal, and a frequency synthesizer 115 for supplying the synthesized frequency signal to the receiver 111 and the transmitter 114.

As shown in FIG. 3, the auxiliary terminal 200 includes a receiver 210 that receives a radio signal transmitted from the data transmitter 150, a data detector 220 that detects data information from the received radio signal, and a detection unit.
