Description

Mobile terminal and method not affecting continuity of communication process when call is interrupted

technical field

The invention relates to a mobile communication terminal and a method for maintaining the continuity of the communication process by means of detection, recording and playback when the call is interrupted, and belongs to the technical field of mobile communication.

Background technique

Now, in the process of calling in daily work and life, it is often impossible to maintain the continuity of the communication process because one party to the call is interrupted. For example, one party to the call is interrupted by a third party during the call, which makes it impossible to receive the information transmitted by the other party, thus causing the communication process to be interrupted due to incoherence. The current mobile terminal technology cannot well solve the problem of how to maintain the continuity of the communication process when the call is interrupted, and often adopts the method of artificially restoring the original communication process by both parties in the call.

At the same time, although mobile phones with voice recording and playback functions have been widely used at present, the time for recording and playback is usually relatively short, and it is necessary to manually start the automatic recording function of the call process before performing the recording operation of the call voice until the call is completed. The recording ends when you hang up. Moreover, the recording can only be invoked after the call ends, and it cannot be played while recording. Therefore, this feature has little effect on maintaining the continuity of the communication process during a call.

After patent search, we found the following Chinese patent application "Mobile Phone for Multifunctional Voice Recording and Playback" (Application No.: 03139179.6), which discloses a mobile phone for multifunctional voice recording and playback, which consists of a user module, a user interface, a system module, SIM card circuit, subscriber identification module, transmitting and receiving circuit, microphone and receiver etc. The user interface that completes the recording function also includes buttons for inputting recording instructions; a liquid crystal display for displaying recording instructions and prompt information; the system module also includes receiving analog voice signals in the receiver, converting them into digital signals through analog/digital conversion, and then converting them into digital signals. After the data is encoded, it is transmitted to the voice coding module of the sound module; it receives the recording instruction of the user interface, and receives the corresponding command and data stream transmitted by the voice coding module, and then stores the voice module of the data stream through the storage module; receives the voice module sent by the voice module A data stream, and a storage module for storing the data stream. The mobile phone can pause/resume, stop, fast forward/rewind, adjust the volume, change the playback path and realize the recording during a call or non-call during the recording and playback process, and set the recorded data as an alarm clock and incoming call ringing , short message, WAP and EMAIL will not affect the software system and performance of existing mobile phones, and can be widely used in mobile communications.

However, no similar mobile phones are on sale in the market so far. Therefore, the applicant believes that even if the above-mentioned mobile phones with voice recording and playback functions are widely used, the recording and playback time of such mobile phones is relatively short, and the automatic recording function of calls needs to be manually activated, and the recording will not end until the call is hung up; and , the recording can only be invoked after the call ends, and recording while playing cannot be realized. This does not have much effect on maintaining the continuity of the communication process during the call. It still does not solve the problem of how to maintain the continuity of the communication process when the call process is interrupted. The effect is very poor, which affects the user experience of both parties in the call and hinders the emotional communication between the two parties.
