Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a wireless communication device and a mobile communication system.

[0002]

2. Description of the Related Art Recently, in mobile communication systems,
In addition to voice communication, functions such as transmission / reception of electronic mail, Web contents, music playback, and video playback are available.

[0003]

However, the conventional mobile communication system has the following problems. (1) Mobile phones and PHS (personal handy phone
In a voice communication in a wireless communication device such as a system), it is necessary to move to a place where the background noise level is low or call again because the received voice is difficult to hear when in an environment where the background noise level is high. Further, in such an environment, it is difficult to hear one's own voice, and thus the transmitted voice is often loud, which may cause discomfort to the other party.

(2) Even when using Web contents including voice in a wireless communication device such as a mobile phone or PHS, it is difficult to hear the voice contents in an environment where the background noise level is high. Therefore, the user moves to a place where the background noise level is low. Alternatively, it may be necessary to stop using the Web content service.

(3) In a situation such as a meeting or at work, voice communication using a wireless communication device such as a mobile phone or PHS will be a nuisance to others, so a voice recording function (service) such as an answering machine service is used. Then, after confirming the recorded contents, the call will be redone, but even if the contents are urgent, the situation cannot be confirmed until the recorded message is heard. In addition, it is difficult to inform the other party of an appropriate reason why the call cannot be answered by voice guidance using a voice recording function such as an answering machine service.

(4) When it is assumed that Web contents are used during a voice call in a wireless communication device such as a mobile phone or PHS, it is difficult to use the voice of the Web contents at the same time as the voice call.

(5) When a voice call is made due to an incoming call when reproducing music or a moving image in a wireless communication device such as a mobile phone or PHS, it is necessary to interrupt the reproduction of the music or the moving image.

The present invention has been made in view of the above points,
Even if the background noise level around the device body is high or there is a risk of disturbing the surroundings during meetings or work, it is possible to reliably grasp the information from the other party, and the voice of the Web content can be heard at the same time as the voice call. An object of the present invention is to provide a wireless communication device and a mobile communication system that can be used or can make a voice call without interrupting music or moving images even if an incoming call is received when reproducing music or moving images.

The coded information is input to the demodulation unit 2 and demodulated. The demodulated speech coded information is stored in the text storage switching determination unit 3
6 is input. If the text storage selection unit 37 has not selected the text storage, the text storage switching determination unit 36 maintains the state in which the changeover switch 4 is set to the voice decoding unit 5 side. Therefore, in this state, the RF demodulation unit 2 demodulates. The encoded audio information is input to the audio decoding unit 5 and the audio signal is decoded. The decoded audio signal is the D / A conversion unit 6
After being converted into an analog voice signal by, the voice is output from the output unit 7.

On the other hand, if the text saving is selected in the text saving selecting section 37, the text saving switching judging section 3
Reference numeral 6 switches the changeover switch 4 to the character conversion unit 10 side so that the audio coded information from the RF demodulation unit 2 is transferred to the character conversion unit 1.
Enter 0. When the voice coded information is input to the character conversion unit 10, the character is converted and displayed on the character display unit 11. When the character conversion unit 10 performs the character conversion process, the text storage use notification unit 38 indicates that the character conversion unit 10 is being used by the user (that is, the listener) of the apparatus and the other party (that is, the sender). ) Will be notified. At the same time, the characters converted by the text storage unit 39 are stored as text in the internal memory.

As described above, according to the wireless communication apparatus of the present embodiment, the contents of the received voice communication are converted into characters and stored as text, so that it can be used as a minutes.
