The mobile wireless terminal device controls each part of the mobile wireless terminal device in a centralized manner, and has a communication control function for establishing communication with the base station BS by establishing a wireless communication link.

Further, the control unit 40 has a function of recording a history of outgoing calls and incoming calls in the storage unit 41 and outputting the history according to a user's request, and as a new control function, a call voice recording control. Means 40a and call voice reproduction control means 40b are provided.

When the communication link is established with the communication partner and the call is started, the call voice recording control means 40a stores the call voice (sending voice and receiving voice) in the storage unit 41 for a predetermined time. The recording is controlled.

The call voice reproduction control means 40b controls the call voice recorded in the storage section 41 by the call voice recording control means 40a in a loud voice according to the user's request.

The storage unit 41 uses, for example, a semiconductor memory such as a ROM or a RAM as a storage medium. The storage medium stores telephone directory data in which names and telephone numbers are associated with each other, and communication history data. It has a storage area 41a, a voice recording work area 41b, and a call voice storage area 41c.

The communication history data storage area 41a is an area for storing a history of outgoing calls and a history of incoming calls. As for outgoing calls, as shown in FIG. 2, the telephone number of the outgoing call destination and the outgoing time are stored in association with each other. For incoming calls, as shown in FIG. 3, the telephone number of the caller and the incoming time are stored in association with each other. Further, in each history, a memory address in which a call voice made by making or receiving the call is stored is associated and stored.

In the voice recording work area 41b, the call recording control means 40a stores the call voice in the call voice storage area 41c.
It is used as a work area when recording. The call voice storage area 41c is an area for storing the voice of a call made for 10 seconds for each call.

The console unit 42 displays keys such as a dial key, a call key, a power key, an end key, a volume control key, and a mode designation key, and a telephone number of a call partner terminal and an operating state of the device. The LCD display shows the discharge state of the battery 30 (battery 3

Next, a description will be given of a process of the mobile radio terminal device having the above-described configuration during a call and a process of reproducing and outputting the call voice stored in this process. First, the processing during a call will be described. This processing is as shown in FIG. 4, and when a call is started by making or receiving a call, the call voice recording control means 40a performs the processing. In parallel with this processing, the control unit 4
0 performs control related to normal communication and records communication history data in the communication history data storage area 41a.

When a call is started by making or receiving a call, in step 4a, the time when the call is originated or the time when the call is made is detected, and the process proceeds to step 4b. In step 4b, the reception voice data before decoding from the PCM code processing unit 8 and the transmission voice data encoded by the PCM code processing unit 8 are associated with each other, and the voice recording work area is treated as one call voice data. The process of recording in 41b is started, and the process proceeds to step 4c.

In order to repeatedly record the call voice data in a predetermined area of the voice recording work area 41b, the predetermined area is, for example, a FIFO in this process.
Use as (First In First Out).

In step 4c, it is determined whether the communication has ended. Here, if the communication is completed, the process proceeds to step 4d. On the other hand, if the communication is not completed, the process proceeds to step 4c to continue the call voice data recording process.

In step 4d, the call voice data recording process started in step 4b is completed, the call voice data recorded in the voice recording work area 41b is recorded in the call voice storage area 41c, and the process proceeds to step 4f. . If there is no free space in the call voice storage area 41c, the oldest one is erased and recorded.

In step 4e, the control unit 40 detects the current communication history data recorded in the communication history data storage area 41a, and the call voice data recorded in step 4d is stored in association with this communication history data. The memory address to be stored is recorded in the communication history data storage area 41a, and the process ends.

Next, a process for reproducing and outputting the call voice stored in the above process will be described. Note that this processing is performed by the call voice reproduction control means 40b.
A flowchart of this process is shown in FIG.

First, in step 5a, an initial value "1" is set in the parameter A, and the process proceeds to step 5b. In step 5b, of the communication history data stored in the communication history data storage area 41a, the communication history data corresponding to the history number A is read out, and the time of the incoming call or the outgoing call and the telephone number of the source or the destination are consoled. It is displayed on the LCD display of the unit 42, and the process proceeds to step 5c.

In step 5c, the console unit 4
It is determined through the key 2 whether or not a request for reproducing the call voice corresponding to the currently displayed communication history is made. If there is a reproduction request, the process proceeds to step 5d. On the other hand, if there is no reproduction request, the process proceeds to step 5f.

In step 5d, the memory address recorded in association with the history number A is detected, the call voice data in the call voice storage area 41c corresponding to this memory address is read out and output to the PCM code processing section 8. Then, the process proceeds to step 5e. Here, the read call voice data is decoded by the PCM code processing unit 8, amplified by the amplifier 9, and then output from the speaker 10 in a loud voice.

In step 5e, the console unit 4
The LCD display of No. 2 displays a message asking for replay such as "Play again?", And the console unit 4
It is determined through the key of No. 2 whether or not a replay request has been made. Here, if there is a request for re-reproduction, the process proceeds to step 5d, while if there is no request for reproduction, the process proceeds to step 5f.

In step 5f, the console unit 4
The LCD display of No. 2 displays a message asking whether to display the next communication history such as "Display next communication history?", And whether or not the above display request is made through the key of the console unit 42. To determine. Here, if there is a display request, the process proceeds to step 5g, while if there is no display request, the process ends.

In step 5g, "1" is added to the value of A, and the process proceeds to step 5h. In step 5h, it is determined whether the value of A is larger than "20". here,
If the value of A is larger than "20", the process is ended, while if it is not larger, the process proceeds to step 5b again.

As described above, when a voice call is started in the mobile radio terminal device having the above configuration, the call recording work area 41b capable of storing the call voice data for 10 seconds is used to record the call. When the control means 40a repeatedly records the call voice and the communication ends, the voice recording work area 4
The call voice data recorded in 1b is recorded in the call voice storage area 41c, and is associated with the current communication history data recorded in the communication history data storage area 41a. Therefore, the call voice for the last 10 seconds is recorded in the call voice storage area 41c.

Then, the communication history data storage area 41a
When reading the communication history stored in, when the user requests the reproduction of the call voice through the key of the console unit 42, the call voice reproduction control means 40b calls the call voice data corresponding to the communication history being displayed. The data is read from the voice storage area 41c and reproduced and output.

Therefore, according to the mobile radio terminal device having the above-mentioned configuration, even if the user forgets the requirement due to a lapse of time or the like, the last part of the intended call can be reproduced and output. It can be remembered and convenience is improved.

In the mobile radio terminal device, when a call is started, the recording of the call is automatically started and the conversation for 10 seconds until the call is ended is recorded. Therefore, when the user ends the call, By repeating the requirements of the conversation made up to that point, the requirements can be surely recorded.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the communication history and the call voice data are associated with each other, and after the communication history is displayed, the call voice reproduction request is accepted. However, instead of this, for example, a request from the user Accordingly, the call voice data recorded in the call voice storage area 41c may be reproduced and output regardless of the display of the communication history.

Further, in the above embodiment, the call voice data for 10 seconds is recorded, but needless to say, it may be longer or shorter than this, and it is not a recording time but a predetermined time. You may make it record the telephone call voice data of data amount. According to this, when the conversation is interrupted, the call voice data is compressed by the encoding process, so that more time is recorded.

Further, in the above-mentioned embodiment, the wireless communication system has been described as an example, but the present invention can be applied to a communication terminal of a wired communication system and may be a wired communication system capable of notifying a caller number. In this case, it is more suitable and the same effect can be obtained. Needless to say, the present invention can be similarly implemented even if various modifications are made without departing from the scope of the present invention.
