The processing at the time of recording and reproduction will be described using one block of the M codec 304, the BT / DT detection unit 312, and the level detection unit 314.

First, the processing at the time of voice recording will be described.

When the CPU 306 confirms the information via the CPU 306 and detects information that matches the ID stored in the own terminal and prompts the storage process, the CPU 306 activates the data storage unit 311 via the DMA controller 309 and the controller 310. This process is a process performed when the data storage unit 311 is configured by a storage unit such as a hard disk or a magneto-optical disk that requires control. Therefore, it is not necessary when a semiconductor memory is used.

Output to the codec 304. As means for mixing digital data as described above, software means using ROM and means using hardware can be considered.

When a call is made on an external line, only one communication channel is used between the fixed unit and the mobile unit. Therefore, it is sufficient to extract the voice data of that channel. In the case of an inter-call, since the two channels of the fixed machine on the calling side and the channel between the mobile stations and the fixed machine on the called side and the channel between the mobile stations are used for the call, the voice data of the channel on the calling side is extracted. It is sufficient to determine in advance whether to perform the operation or to retrieve the audio data of the channel on the receiving side.

The ADPCM codec 304 converts the received compressed data into an analog signal and outputs the analog signal to the BT / DT detecting section 312 and the level detecting section 314. B

U306 checks the state of the bus, and
9, a signal indicating that the bus is open is returned, and control information is transmitted.

When detecting that the right to use the bus has been obtained, the DMA controller 309 performs DMA transfer and
Transfer is performed between the CM codec 304 and the RAM 308, and audio data is stored in a first storage area in the RAM having a predetermined size. When detecting that the first storage area is full, the CPU 306 performs processing for storing an audio signal in the second storage area.

In parallel with the start of the storage operation in the second storage area, the storage processing from the first storage area to the data storage unit 311 is performed. The storage processing in the data storage unit 311 ends before the second storage area becomes full. C
When the second storage area is full, the PU 306 starts storing the data again in the first storage area, and repeats this to perform the processing of storing the sound in the storage unit 311. This storage processing is to store the data in the area of the data storage unit 311 corresponding to the extension number of the mobile device itself unless the storage region is specified by the mobile device. It is also possible to store voice data in an area corresponding to an outside line number.

In order to stop such voice storage processing, the CPU 306 detects a disconnection request signal from the mobile device or the fixed device via the modem 305,
BT / DT detection unit 31 via PCM codec 304
If the CPU 306 detects the DT signal indicating the end of the call for a predetermined period of time, the end processing is performed.

After the end of such storage processing, a signal indicating a change in the storage area is received from the mobile unit by the antenna 301, and the transmission / reception unit 302, the modem 305, and the frame processing circuit 303
When the CPU 306 confirms via
The data transfer to the area indicated by the change is performed by the controller 3.

When the CPU 306 detects a signal requesting a call setting from the mobile device during this process, it outputs a response signal to this signal, and the mobile device enters a communication state with the mobile device.

When the CPU 306 detects that the communication state has been established, the CPU 306 instructs the voice message output unit 313 to output predetermined guidance. In response to this instruction, the voice message output unit 313 outputs predetermined guidance stored in a memory provided in the voice message output unit 313 to the AD bus 316.

The CPU 306 inputs the guidance data to the frame processing circuit 303. Upon receiving the voice signal, the frame processing circuit 303 puts the voice signal in a predetermined slot, converts the voice signal into a predetermined frame, outputs the frame to the modem 305, and outputs voice guidance to the mobile device via the transmission / reception unit 302 and the antenna 301.

Although the voice guidance is output in the present embodiment, a sound having a predetermined frequency that can be confirmed on the mobile device side may be used instead.

When the end of the voice guidance is detected, the CPU 306 performs a process for detecting address information of voice data from the mobile device.

During this processing, when the CPU 306 detects the dial information from the mobile device via the antenna 301, the transmitting / receiving unit 302, the modem 305, and the frame processing circuit 303, it is stored in the data storage unit 311 corresponding to the dial information. The processing for reading the message is performed via the controller 310.

In this process, first, the CPU 306 outputs a command to the controller 310 to output voice data in a predetermined area based on extension / external line information. The controller 310 that has received this command stores the data in the data storage unit 31.
1. The audio data in a predetermined area in the
0 is stored in the buffer.

When the buffer becomes full, a request for DMA transfer of the audio data in the buffer is issued to D.
Request to MA controller 309. When this request is accepted, the DMA controller 309 performs a DMA transfer between the controller 310 and the RAM 308.

When the CPU 306 detects that the transfer to the first storage area of the RAM 308 has been completed, the CPU 306 outputs an instruction to the frame processing circuit 303 to request a DMA transfer. Upon receiving this instruction, the frame processing circuit 3
03 makes a DMA transfer request to the DMA controller 309.

When this request is accepted, the DMA controller 309 sends the request to the RAM 308 and the frame processing circuit 3
03 is performed. In parallel with such DMA transfer of the first storage area of the RAM 308, the RAM 308
From the controller 310 to the second storage area
Audio data is stored by MA transfer.

When the DMA transfer of the audio data in the first storage area of the RAM 308 to the frame processing circuit 303 ends, the DMA transfer to the frame processing circuit 303 in the second storage area starts. Hereinafter, by repeating this, the audio data stored in the data storage unit 311 can be read.

FIGS. 6 and 7 are flow charts showing the operation of the main apparatus in the present embodiment at the time of setting for performing voice storage.

If the mode is set in the mobile device in S002 while the standby process is being performed in S001, it is confirmed in S003 that the mode is the voice storage process setting mode.
If the mode is not the voice accumulation mode, the process proceeds to another process. S
When the setting of the voice storage processing is selected in 003, S004
Confirm whether to set the outside line mode. In the case of setting the outside line mode, in S005, it is determined whether or not all outgoing / incoming calls to the outside line store the call.

If it is selected in S005 to store outgoing / incoming calls to / from all external lines, then in S011, a setting for storing the calls in all external lines is made, and in S008, it is confirmed whether to end the setting mode. If the setting mode is not to be ended, the setting process is selected again in S003.

If it is selected that all outgoing / incoming calls to / from an external line are not stored in S005, a setting is made in S006 as to whether or not to store only a predetermined external line instructed by the mobile station. If the storage of only the predetermined outside line is not performed in S006, the process returns to S005. If it is set in S006 that the voice storage processing is to be performed only on a predetermined outside line (for example, voice storage is performed only for an incoming call from the outside line 1 and voice storage is not performed for outgoing / incoming calls using other lines). A process for storing the setting information is performed, and whether to end the setting mode is selected in S008.

If the outside line setting mode is not selected in S004, it is confirmed in S012 whether to set the inside line mode. If the extension mode setting is selected in S012,
In S013, it is confirmed whether all outgoing / incoming calls at the extension are stored. If all communications are to be stored at the time of outgoing / incoming calls at the extension in S013, an extension mode setting process is performed at S017. S
If it is selected that all calls are not stored when making or receiving an extension at 013, a selection is made at S014 as to whether or not to store the call when only a predetermined extension specified by the mobile device is made or received. . (For example, in the case of an internal / external line transmission using the extension 1 and an internal / external line incoming to the extension 1, the call storage processing is performed and not performed at other terminals. The call storage is performed only when a manual request is made. If the extension is not set in S014, a selection is made in S016 as to whether or not call recording is to be automatically performed for all extensions when making and receiving calls. If the setting is not performed in S016, the setting of the recording process is continued during the extension call in S013. If it is selected in S016 that no voice recording should be performed in all extension calls, an extension mode setting process is performed in S015.

When the processing is completed, the end of the setting mode is confirmed in S008. If the end of the setting mode is confirmed, it is confirmed in S009 whether or not the setting mode has been changed. Move to the processing of. S

When the process is completed, a call setting process with the fixed device is performed in S118. When the call setting process is completed, the mobile unit performs ringing in S119 according to a command from the fixed unit.

If the response operation from the mobile device is not performed in S120 while the mobile device is sounding in S119, the sound processing of the mobile device is continued in S118.

If a response operation has been performed in S120, it is determined in S123 whether the designated extension or designated outside line is to be used for voice recording. If the voice recording is not specified in S123, the process at the time of the telephone call is performed in S125. If the voice recording is specified in the S123, the voice storage request transmission process is performed in S124, and the process at the time of the voice communication is performed in S125.

Also, when there is an incoming call request from the fixed machine, each phase ID and the voice accumulation processing permission signal are transmitted and received.

In the above configuration, when an incoming call is received from the general subscriber line 1101 to the outside line 1 of the main unit 1102, the extension terminal corresponding to the incoming call is sounded. Here, assuming that extension 1 corresponds to outside line 1, fixed unit 1103 of extension 1 notifies mobile unit 1106 that there is an incoming call from outside line 1. Upon detecting that there is an incoming call from the outside line 1, the mobile device 1106 performs a process for ringing the incoming call, turns on an LED indicating a predetermined outside line, and sounds a ring tone.

At this time, when a control signal (ID and available channel information) at the time of an incoming call from the mobile device 1106 is detected, preparation for recording a call (for example, transition from a standby state of an IC or a hard disk to an idle state) is performed.

Subsequently, a control signal (ID and communication channel movement information) from mobile device 1106 is detected. Thereafter, upon detecting a response signal (ID and communication channel information and extension and outside line information) from the fixed unit 1103, the cordless voice storage device 1109 converts the subsequently transmitted voice signal to a predetermined address based on the extension and outside line information. A process for storing is performed.

When a call is transmitted from the mobile device 1106, the off-hook signal (ID and transmission request) of the mobile device 1106 is detected by the antenna, and the cordless voice storage device 110
Reference numeral 9 makes preparations for recording a call (for example, transition from a standby state of an IC or a hard disk to an idle state).

Thereafter, detection of a signal (ID and free channel movement information) from the mobile device 1106 and detection of a signal (ID and free channel movement information and extension / external line information) from the fixed device 1103 are performed. Then, an area for storing voice data is determined based on the extension and outside line information from the fixed device 1103. Thereafter, when a transmission signal (ID and dial information) is output from mobile device 1106, the dial information is transmitted to main device 1102 via fixed device 1103.

Based on this information, main apparatus 1102 makes a call to an extension or an outside line. When a response is made from the extension and the outside to this transmission, main device 1102
This response information is detected and notified to the fixed device 1103. Upon detecting this response signal, fixed device 1103 outputs a signal indicating that a predetermined response has been made to mobile device 1106 and the voice storage device.

To read out the audio data stored in the audio storage device, the user presses the read key 1209 of the mobile device. Upon detecting that the read key 1209 has been pressed, the CPU 1206 sends a request signal (ID, channel information, and extension information) for accessing the voice storage device to the modem unit 208. The modem 1208 modulates this signal into an analog signal, and

It is composed of

In FIG. 25, antenna 1301
To modem 1305 are blocks for 1ch,
In the case of having 4 ch, as shown by the broken line in FIG.
This requires four blocks. In the second embodiment, the processing at the time of recording and reproduction will be described using this one block.

First, the processing at the time of voice recording will be described.

[0206] A signal indicating the outgoing or incoming call from the transfer motives and fixing machine (ID and outgoing requests A call channel information) received by the antenna 1301, a receiving unit 1302, an audio processing circuit 1303, via the modem 1305 CPU 13
06 confirms the outgoing / incoming call signal, the CPU 1306
Is a data storage unit 1311 via the controller 1310
To start. This processing is performed in the data storage unit 131.
This process is necessary when a hard disk, a magneto-optical disk, or the like that needs to be controlled is used in the first method, and is unnecessary when a semiconductor memory is used.

Subsequently, when the CPU 1306 detects a signal (ID, idle channel information and extension / external line information) indicating a response from the mobile unit or the fixed unit, the CPU 1306
Commands the audio processing circuit 1303 to output the received analog signal to the modem 1305 and the codec 1304. In response to this instruction, the voice processing circuit 130
3 outputs the received audio signal to the modem 1305 and the codec 1304. This makes it possible to receive the control data while receiving the audio data.

At this time, the analog signal received at the time of outside line communication is to receive two analog signals, that is, an analog signal transmitted from the fixed device to the mobile device and an analog signal transmitted from the mobile device to the fixed device. At the time of a call, an analog signal between a fixed device and a mobile device on the calling side or the called side may be received. Also during this inter-extension call, two signals, an analog signal transmitted from the fixed device to the mobile device and an analog signal transmitted from the mobile device to the fixed device, are received.

The codec 130 receiving the audio signal
In step 4, this signal is sampled every 8 kHz, and when the output data is determined, a DMA request is output to the DMA controller 1309. Upon receiving this request, the DMA controller 1309 issues a bus release request to the CPU 1306. In response to this request, CPU
1306, the DMA controller 13 checks the state of the bus.
A signal indicating the release of the bus is returned to the control signal 09 and control information is transmitted.

When the DMA controller 1309 detects that the right to use the bus has been obtained, a DMA transfer is performed, a transfer is performed between the codec 1304 and the RAM 1308, and the data is transferred to the first storage area in the RAM having a predetermined size. The voice data is stored. When the CPU 1306 detects that the first storage area is full, the CPU 1306 performs processing for storing an audio signal in the second storage area.

Next, in parallel with the start of the storage operation in the second storage area, the data storage unit 13 is moved from the first storage area.
11 is stored. Then, the data storage unit 1
The storage processing to 311 ends before the second storage area becomes full.

[0212] When the second storage area is full, the CPU 1306 starts storage in the first storage area again, and repeats this operation to perform processing for storing sound in the storage unit. In this storage processing, when there is no particular designation of a storage area from the mobile device, the voice is stored in the area of the storage unit corresponding to the extension number of the mobile device itself. Note that storing voice data in an area corresponding to an outside line number is also conceivable.

To stop the voice storage process, the CPU 1306 detects the on-hook signal from the mobile device or the fixed device via the modem 1305, and the codec 13
04 from the BT / DT detection unit 312 to the CPU 130
When the DT signal has been detected for a predetermined time, the end processing is performed.

After the storage processing is completed, a signal indicating a change in the storage area is received from the mobile device by the antenna 1301, and the transmission / reception section 1302, the voice processing circuit 1303, and the modem 1305 are received.
When the CPU 13 06 confirms via the
Commands the controller 1310 to transfer data to the area indicated by this change.

In response to this command, the controller 1310
Transfers data from the storage area corresponding to the mobile device in the data storage unit 1311 to the area requested to be changed.

When the transfer is completed, the controller 1310 notifies the CPU 1306 of the completion of the transfer. Upon receiving this notification, the CPU 1306 notifies the mobile device of the end of the transfer.

Next, the processing at the time of audio reproduction will be described.

First, signals (ID,
Vacant channel information and extension / external line information) are received by the antenna 1301,
When the CPU 1306 confirms via the modem 303 and the modem 1305, it determines whether or not the reception is possible.

[0219] If acceptable, the response signal is output to modem 1305, and the response signal (ID and idle communication channel, extension, external information) is transmitted to the mobile device via voice processing circuit 1303 and antenna 1301. . When the CPU 1306 detects that the call has been established, the CPU 1306 instructs the voice message output unit 1313 to output predetermined guidance.

In response to this command, voice message output unit 1
313 outputs predetermined guidance stored in the memory onto the bus. The CPU 1306 inputs the guidance data to the codec 1304, performs D / A conversion, and outputs an analog signal to the audio processing circuit 1303. Upon receiving the voice signal, the voice processing circuit 1303 outputs voice guidance to the mobile device via the transmission / reception unit 1302 and the antenna 1301. Although the voice guidance is output in the present embodiment, a sound having a predetermined frequency that can be confirmed on the mobile device side may be used.

When the end of the voice guidance is detected,
The CPU 1306 performs a process for detecting address information of voice data from the mobile device.

When CPU 1306 detects dial information from the mobile device via antenna 1301, transmitting / receiving section 1302, and modem 1305 during this processing, the CPU 1306 reads a message stored in storage section 1311 corresponding to the dial information. The processing is performed via the controller 1310.

First, the CPU 1306 controls the controller 13
10, an instruction to output voice data in a predetermined area based on extension / external line information is output. The controller 1310 that has received this instruction causes the buffer in the controller 1310 to store audio data in a predetermined area in the data storage unit 1311.

When the buffer becomes full, a request for DMA transfer of the audio data in the buffer is issued to the DMA controller 1309. When this request is accepted, the DMA controller 1309
10 and the RAM 1308 perform a DMA transfer. RAM1
The completion of the transfer to the first storage area at 308
When U1306 detects, DMAC is
Outputs an instruction to request a transfer.

In response to this instruction, codec 1304
A DMA transfer request is issued to the DMA controller 1309. When this request is accepted, the DAM controller 1309 makes the RAM 1308 and the codec 1304
DMA transfer is performed between them. In parallel with the DMA transfer in the first storage area of the RAM 1308, audio data is stored in the second storage area of the RAM 1308 by DMA transfer from the controller 1310.

When the DMA transfer of the audio data in the first storage area of the RAM 1308 to the codec 1304 is completed, the D is subsequently transferred to the codec 1304 in the second storage area.
MA transfer starts. By repeating this, the audio data stored in the data storage unit 1311 can be read.

The audio processing circuit 1303 used in the second embodiment is composed of a limiter, a compander and the like, all of which are publicly known.

The conversion method of the codec for performing A / D conversion of audio data is not particularly limited as long as it is PCM, ADPCM, etc., and the bus configuration is 8, 16, 32, There is no particular limitation as long as it is 64 bits or the like.

If the ID and channel information and the like cannot be detected in S1105 and S1108, in S1113 a process is performed when a connection with the fixed machine is not possible (warning sound or display indicating that transmission to the display unit is not possible) is performed. The processing shifts to the standby processing.

When the ID, channel information, and control information are detected in S1108, a process for inputting a dial is performed in S1109. This processing indicates processing such as DT output at the time of transmission of an inside / outside line.

After this processing, when a dial is inputted in S1110, a signal indicating the response of the other party is detected in S1111 and a predetermined response signal is output. After outputting this signal, in S1112, a process for making a call with the fixed device is performed, and a normal call is made.

If the ID and free channel data cannot be detected in S1306, the audio data reading process ends in S1311, and the process shifts to a standby process.

The data input after performing this processing is
The data indicates the address. In this way, by inputting a predetermined number, it is determined which data in the storage unit is to be output.

When a predetermined number is input in S1308, monitoring of information from the voice storage device indicating whether voice data corresponding to the input address data exists in S1309 and whether output is possible is performed. And S1
When a signal indicating that output from the voice storage device is possible is detected in 309, voice data from the voice storage device is accepted and a message can be heard in S1310.

If the ID and free channel data cannot be detected in S1308, the reading process of the audio data is terminated in S1311, and the process shifts to a standby process.

A signal for prompting the output of the voice message is output to the voice storage device.

If there is no output request for another voice message in S1403, the flow shifts to voice message listening end monitoring processing in S1401.
