[Previous technology]

When recording, tape recorders were mainly used, but nowadays, recording devices such as MD recorders and memory recorders have become widespread, making recording easier. However, it is rare to carry these recording devices at all times, and when a situation occurs in which recording is suddenly required, recording fails. Moreover, even though these devices have been miniaturized, it is still troublesome to carry them all the time.

【0003】

By the way, in recent years, mobile phones have become widespread. In particular, the spread of mobile phones is remarkable, and many people carry mobile phones with them at all times.

【0004】

Therefore, if a mobile phone can be used as a recording device, it is not necessary to carry a recording device such as a tape recorder, an MD recorder, or a memory recorder, which is very convenient. Moreover, even if a situation occurs in which recording is suddenly required, it is possible to prevent the recording from being missed. However, if a mobile phone is equipped with a large-capacity memory so that recording can be performed for a long time, the outer shape of the mobile phone becomes large, the weight increases, and the portability is impaired.

【0005】

Therefore, if a recording service center is provided instead of recording on the mobile phone and recording is performed on the information processing device of the recording service center, it is possible to suppress the increase in size and weight of the mobile phone.

【0006】

For this reason, various proposals have been made. For example, in Japanese Patent Application Laid-Open No. 2000-299752, a memory means for recording a voice signal picked up by a microphone built in or externally attached to a mobile phone, and a time when the voice signal input to the memory means is completed or determined in advance. When the capacity is reached, the recorded contents of the memory means are recorded in the recording server of the service institution through the telephone line network, and the contents recorded in the recording server when the customer requests are recorded through the telephone line network. Or, a recording system using a mobile phone provided with a means for recording on another recording medium and returning it to the customer has been proposed.

【0007】

[Problems to be Solved by the Invention]

However, in the technique of the above publication, when the state of the memory for recording the voice signal is full and the state of the wireless line deteriorates, the voice signal is lost.

【0008】

Therefore, the problem to be solved by the present invention is the loss of voice data even when the wireless line condition deteriorates or the wireless line is disconnected while transmitting voice data from the mobile phone to the information processing device of the recording service center.
