Abstract

PROBLEM TO BE SOLVED: To provide a portable telephone set that is affected less by electromagnetic waves. SOLUTION: This portable telephone set consists of a user operation section 5, including at least a key operation section, a display section, a microphone, a speaker or the like, and a mobile main body 4 including an antenna 2, a radio communication section, a modulation/demodulation section, a protocol control section, a vocoder section and a communication control section or the like, and the user operation section 5 and the mobile main body 4 are designed as separate units to set apart the mobile main body 4 from a human body and data are sent/received by the use of a radio channel or a wired channel, then the effects from electromagnetic waves are reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In the present invention, a portable telephone, especially a terminal for satellite communication, has to increase the transmission output from an antenna due to the necessity of communicating with a satellite in the sky. Therefore, a mobile phone having a structure for reducing the influence of electromagnetic waves is provided.

[0002]

2. Description of the Related Art In a conventional portable telephone, a place where an antenna for transmitting and receiving a radio wave is provided is designed to be as far away from a user as possible in order to reduce the influence of an electromagnetic wave. That is, in order to keep the antenna position as far as possible from the user, for example, a structure in which the angle between the main body and the antenna is inclined has been considered.

[0003]

As described above, the conventional portable telephone has a structure in which the main body and the antenna are separated as much as possible within the same terminal. However, when a mobile phone, especially a satellite communication terminal, communicates with a satellite in the sky, it is uneasy about the effect on the human body by simply tilting the angle between the main unit and the antenna to transmit strong radio waves. There are people.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve these problems. In a portable telephone having a function of reducing the influence of electromagnetic waves, at least a key operation unit, a display unit, a microphone, It is composed of a user operation unit including a speaker and the like, an antenna, a wireless communication unit, a modem unit, a protocol control unit, a vocoder unit and a mobile unit main unit including a communication control unit, etc., in order to separate the mobile unit main unit from a human body. Provided is a mobile phone in which a user operation unit and a mobile unit main body are separated from each other to transmit and receive data wirelessly or by wire.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram illustrating a relationship between a mobile phone and a satellite according to one embodiment of the present invention, and FIG. 2 is a block diagram of a mobile phone according to one embodiment of the present invention. In FIG. 1, 1 is a satellite, 2 is an antenna,
3 is a mobile phone, 4 is a mobile unit main body, and 5 is a user operation unit. As shown in FIG. 1, the mobile phone 3 is a mobile unit because the mobile unit main unit 4 and the user operation unit 5 are separated. The main body 4 can be provided away from the human body.

In FIG. 2, the same members as those in FIG. 1 are denoted by the same reference numerals. In the user operation unit 5, 51 is a keypad for inputting data, 52 is a display for displaying data, 53 is a SIM card, 54 is a microphone, 55 is a speaker, 56 is an MMI (man-machine interface), 58 Is SIMI / F, 59 is P
It comprises a CM codec and a communication control unit 57.

Next, in the mobile unit 4, 47 is a communication control unit for communicating with a communication control unit 57 provided in the user operation unit 5, 46 is a vocoder, 45 is a protocol control unit, and 44 is a SIM. Card, 43 is SIMI
/ F and 42 are a modulation / demodulation unit and 41 is an RF unit. The communication control unit 57 of the user operation unit 5 and the communication control unit 47 of the mobile device body 4 perform (1) communication using FM radio waves, (2) communication using infrared rays, and (3) communication using a physical cable. Can communicate in a way.

The operation will be described with reference to FIGS. 1 and 2. When the mobile phone 3 is actually used, the user operates the user operation unit 5 as a conventional handset and talks. The mobile device body 4 is placed at a position away from the head (for example, attached to a hand-held bag), and communicates with the satellite 1 by radio waves transmitted therefrom. That is, the mobile device main body 4 that outputs the electromagnetic wave is separated from the human body.

In the above-mentioned communication control section (1) communication using FM radio waves and (2) communication using infrared rays, a redundant section is added to transmission data because an error may occur in the course of communication processing. The receiving unit performs error correction processing or transmits with a reduced number of redundant parts, and the receiving unit performs only error detection. When an error is detected, retransmission processing is performed. It is also effective to use a combination of (1) communication using FM radio waves and (3) communication using a physical cable. If a cable is connected, communication is performed using the cable. Otherwise, communication is performed using FM radio waves.

[0010]

As described above, according to the present invention, in order to disconnect a mobile unit main body including an antenna for transmitting a strong electric wave from a human body and talk with the user, a cable or a user operation unit including a microphone and a speaker is provided. By adopting a structure in which connection is made using wireless communication, influence from electromagnetic waves can be reduced.
