Are connected to the private base station 4, the public base station 3, and the private base station 4 via a wireless line.
[0035]
A network supervision station 6 and a voice mail center 7 are connected to the communication line network 1. The network supervision station 6 is connected to the database 8. This database 8 stores the subscriber number, billing information, location registration information of the PHS terminal 5, and information on the presence / absence of voice mail.
[0036]
Further, the voice mail center 7 stores predetermined message information and has a recording / reproducing means. When the incoming call setting to the PHS terminal 5 is established and there is no response for a certain period of time, the voice mail center 7 A message is sent to the caller, a requirement message from the calling party is recorded, and a recorded voice mail is played back.
[0037]
FIG. 4 shows the recording status of voice mail in the recording / playback means of the voice mail center 7. In this case, in order to distinguish the played mail together with the PS (PHS terminal) telephone number and the PIN number of the PHS terminal. Recording codes and voice mails can be recorded up to N from # 1 to #N.
[0038]
FIG. 2 shows a schematic configuration of a base station applied to such a radio communication system. Hereinafter, the self-supporting base station 2 provided in the home area HA will be described as an example.
In this case, 11 is an antenna, and a transmission / reception device 12 is connected to the antenna 11. The transmission / reception device 12 includes a frequency conversion unit and a modem. On the reception side of the frequency conversion unit, a signal input from the antenna 11 is input via an antenna switch that distributes transmission / reception, and is transmitted from a PLL synthesizer. By mixing with a local oscillation signal having a predetermined frequency to be output, the frequency is converted from the 1.9 GHz band to an IF signal in the vicinity of 1 MHz.
[0039]
On the other hand, on the transmission side, the π / 4 shift QPSK modulated wave input from the modem is mixed with a local oscillation signal of a predetermined frequency output from the PLL synthesizer to convert the frequency to 1.9 GHz band, and the antenna switch Radiation from the antenna 11.
[0040]
On the receiving side of the modem, the IF signal from the frequency conversion unit is demodulated and separated into IQ data, which is transferred to the communication control unit as a data string. On the other hand, on the transmission side, IQ data is generated from the data transferred from the communication control unit, modulated to π / 4 shift QPSK, and output to the frequency conversion unit.
[0041]
Then, a communication control unit 13 and a voice processing unit 14 are sequentially connected to the transmission / reception device 12, and an NCU (Network Control Unit) 15 is connected to the voice processing unit 14.
[0042]
Here, the communication control unit 13 performs frame synchronization and slot data format processing. On the receiving side, data for one slot is extracted from the received data sent from the modem of the transmitting / receiving unit 12 at a predetermined timing. After extracting a unique word (synchronization signal) from the data to achieve frame synchronization and canceling the scramble of the control data part and the voice data part, the control data is sent to the control part 17 described later, and the voice data is voiced. Transfer to the processing unit 14.
[0043]
On the other hand, on the transmission side, control data or the like is added to the audio data sent from the audio processing unit 14, scrambled or the like, and then a unique word or the like is added to create transmission data for one slot, with a predetermined timing. Then, it is inserted into a predetermined slot in the frame and sent to the modem of the transmission / reception unit 12.
[0044]
The speech processing unit 14 is composed of a speech codec and a PCM codec. Of these, the speech codec performs digital data compression / decompression processing. On the receiving side, the ADPCM speech signal (from the communication control unit 13) By decoding 4 bits × 8 KHz = 32 Kbps) into a PCM audio signal (8 bits × 8 KHz = 64 Kbps), the data is expanded and output to the PCM codec. On the other hand, on the transmission side, the PCM audio signal sent from the PCM codec is encoded into an ADPCM audio signal, compressed and output to the communication control unit 13.
[0045]
The PCM codec performs analog / digital conversion processing, and the receiving side performs D / A conversion on the PCM audio signal sent from the speech codec and outputs the analog audio signal to the NCU 15. On the other hand, on the transmitting side, the analog audio signal input from the NCU 15 is A / D converted and a PCM audio signal is output to the speech codec.
[0046]
The NCU 15 performs mutual conversion between a voice signal and a call voice. Here, the NCU 15 is connected to the communication line network 1 as well as the handset 16. A control unit 17 is connected to the transmission / reception unit 12, the communication control unit 13, the voice processing unit 14, and the NCU 15. The control unit 17 is connected to a ROM 18, a RAM 19, a voice mail recording / reproducing unit 20, a key input unit 21, and a display. The part 22 is connected.

The ROM 18 stores a control program in the control unit 17. The RAM 19 temporarily stores data handled under the control of the control unit 17.
[0048]
The voice mail recording / reproducing unit 20 is activated by an access signal of the voice mail center 7 output from the control unit 17 and records the voice mail sent from the voice mail center 7 and also stores the recorded voice mail in the PHS. Reading can be performed in response to a request from the terminal 5.
[0049]
FIG. 5 shows the recording status of voice mails in the voice mail recording / reproducing unit 20, and N voice messages up to # 1 to #N, together with PS (PHS terminal) telephone numbers and the PIN numbers of the PHS terminals. It is possible to record up to.
[0050]
If the voice mail recording / reproducing unit 20 is shared with the answering machine recording / reproducing device, two functions can be realized by one device.
The key input unit 21 is for inputting a key operation signal for setting each function to the control unit 17. The display unit 22 includes, for example, a dot matrix type liquid crystal display panel and its drive circuit, and displays input data and results for various controls.
[0051]
In addition, although the said structure has shown the structural example of the private base station 2 of the home area HA, it is fundamentally the same also in the private base station 4 provided in the business establishment (company) area WA, The self-supporting base station 4 may be configured such that the handset 16, the key input unit 21, and the display unit 22 that are necessary as a base unit having the above configuration are deleted.
[0052]
Next, FIG. 3 shows a schematic configuration of the PHS terminal 5.
In this case, 31 is an antenna, and a transmission / reception device 32 is connected to the antenna 31. Then, a communication control unit 33 and a voice processing unit 34 are connected to the transmission / reception device 32 in this order, and a speaker 35 on the reception side and a microphone 36 on the transmission side are connected to the voice processing unit 34. In this case, the voice processing unit 34 is also composed of a speech codec and a PCM codec, and a PCM voice signal sent from the speech codec is D / A converted by the PCM codec and an analog voice signal is output to the speaker 35. The analog audio signal input from 36 is A / D converted and a PCM audio signal is output to the speech codec.
[0053]
Further, a control unit 37 is connected to the transmission / reception unit 32, the communication control unit 33, and the voice processing unit 34, and a ROM 38, a RAM 39, a key input unit 40, and a display unit 41 are connected to the control unit 37.
[0054]
In this case, the details of these units are the same as the configuration of the private base station 2 described with reference to FIG.
Next, the operation of the embodiment configured as described above will be described.
[0055]
In this case, the self-supporting base station 2 provided in the home area HA and the PHS terminal 5 connected to the self-supporting base station 2 via a wireless line will be described.
Now, when a call is received from the communication line network 1 to the PHS terminal 5 via the private base station 2, the call is transferred after waiting for a response from the PHS terminal 5 on the called side. Also, if there is no response for a certain period of time after the PHS terminal 5 establishes the incoming call setting for the incoming call, it switches to the voice mail center 7 and a predetermined message flows to the calling side. The requirement message is recorded in the recording / reproducing means.
[0056]
In this way, the voice mails of # 1 to #N are sequentially recorded in the recording / reproducing means of the voice mail center 7 in correspondence with the PS telephone number and password corresponding to the PHS terminal 5 as shown in FIG. Is done.
[0057]
From this state, first, in the flowchart shown in FIG. 6, the private base station 2 determines whether or not a certain time has elapsed in step 601. If the certain time has elapsed, the voice mail center 7 is automatically instructed in step 602. Access. In this case, the private base station 2 transmits to the voice mail center 7 the PS telephone number and the password corresponding to the PHS terminal 5 handled by the private base station 2 and inquires about the presence of voice mail.
[0058]
When the voice mail center 7 determines in step 701 that there is an access from the private base station 2, the voice mail corresponding to the PS telephone number and the personal identification number is searched from the recorded contents shown in FIG. 4 in step 702. . Then, in step 703, the voice mails of # 1 to #N shown in FIG. 4 that are not written in the reproduction code are regarded as new voice mails, and it is determined whether there is a new voice mail.
[0059]
Here, if there is no new voice mail, the process is terminated. On the other hand, if there is a new voice mail, in step 704, the corresponding new voice mail is read and reproduced and transmitted to the private base station 2.
[0060]
In step 705, the reproduction code is written in the voice mail after reading. Further, in step 706, it is determined whether all reading of new voice mail has been completed. Here, if all the processes have been completed, the process is terminated. If there is a new voice mail, the next voice mail is read out in step 707, and the process returns to step 704 to further read out the next voice mail. Repeat playback.
[0061]
On the other hand, when the private base station 2 receives the voice mail reproduced from the voice mail center 7, it is recorded in the voice mail recording / reproducing unit 20 in step 603. In this case, the voice mail recording / reproducing unit 20 records the voice mail sent from the voice mail center 7 in association with the PS telephone number and the password corresponding to the PHS terminal 5 as shown in FIG.
[0062]
In step 604, it is determined whether all new voice mail recordings from the voice mail center 7 have been completed. If the process has been completed, a lamp indicating that a new voice mail has been recorded is turned on in step 605, and the process returns to step 601 to prepare for the operation after the next fixed time. On the other hand, if a new voice mail is sent, the process returns to step 603 to continue recording the voice mail.
[0063]
FIG. 7 shows a flowchart in the case where the voice mail is read from the PHS terminal 5 to the self-supporting base station 2 in which the voice mail is sequentially recorded in the voice mail recording / reproducing unit 20 as described above.
[0064]
In this case, the PHS terminal 5 first draws in a control channel for connecting to the private base station 2 in step 801. In step 802, the private base station 2 is accessed.
[0065]
When the private base station 2 determines that there is an access from the PHS terminal 5 in step 901, the PS telephone attached to the PHS terminal 5 from the recorded contents shown in FIG. 5 of the voice mail recording / reproducing unit 20 in step 902. Search for voicemails corresponding to numbers and PINs. When the presence of voice mail is detected, a voice mail presence signal is transmitted to the PHS terminal 5 in step 903.
[0066]
The PHS terminal 5 displays the presence of voice mail in step 803. Then, an event becomes possible in step 805 until an end code is received from the private base station 2 in step 804. In this case, if PLAY / FF / REW is operated from the key input unit 40, the reproduction process for the voice mail recording / reproducing unit 20 of the private base station 2 is executed in step 806, and if DEL is operated, the DEL code is obtained in step 807. When the STOP is operated, the STOP code is transmitted at step 608.
[0067]
On the other hand, when the control signal is received in step 904 due to the event in step 805 of the PHS terminal 5, the private base station 2 executes the following operation. In this case, for the PLAY / FF / REW operation, reproduction processing is first executed in step 905. For a DEL code by a DEL operation, the voice mail is deleted at step 906, and further, a playback stop is executed at step 907 for a STOP code by a STOP operation.
[0068]
Thereafter, when the end of the private base station 2 is judged at step 908, an end code is transmitted to the PHS terminal 5 at step 909.
When the PHS terminal 5 receives the end code from the private base station 2 in step 804, the playback end is displayed in step 809, and the process ends.
[0069]
FIG. 8 shows a flowchart of the playback process in the PHS terminal 5 for the voice mail recording / playback unit 20 of the private base station 2, and FIG. 9 shows a flowchart of the playback process in the private base station 2 for the playback process in the PHS terminal 5. .
[0070]
In this case, in the PHS terminal 5, when the FF is operated in the event of step 1001, an FF code is transmitted in step 1002, and when REW is operated, the REW code is transmitted in step 1003. When PLAY is further operated, a PLAY code is transmitted in step 1004.
[0071]
On the other hand, when the private base station 2 receives the control signal in step 1101, the voice mail fast-forward process to be read from the voice mail recording / reproducing unit 20 is executed in step 1102 for the FF code, and the REW code is set. On the other hand, in step 1103, the voice mail fast rewinding process to be read from the voice mail recording / reproducing unit 20 is executed. For the PLAY code, in step 1104, the voice mail is read from the voice mail recording / reproducing unit 20 and reproduced. Then, in step 1005 of the PHS terminal 5, the reproduced voice mail from the voice mail recording / reproducing unit 20 is heard by the PHS terminal 5.
[0072]
Therefore, in this way, the self-supporting base station 2 accesses the voice mail center 7 every time a certain time elapses, reads out the corresponding voice mail to the PHS terminal 5 handled by the self-supporting base station 2, and stores these in the self-supporting base station 2. Is recorded in correspondence with the PS telephone number and the password corresponding to the PHS terminal 5, and if there is a voice mail reproduction request from the PHS terminal 5 thereafter, it corresponds to the PHS terminal 5. Since only the voice mail corresponding to the PS phone number and the personal identification number is read and reproduced on the PHS terminal 5, the voice mail addressed to the self can be confirmed from the PHS terminal 5 by using the normal answering function. It is possible to retrieve the voice mail from the conventional PHS terminal and check whether the voice mail has arrived at the voice mail center. Compared to those for performing operations such as accessing a call center can be an operation for confirming the extraction of these voice mail easily.
[0073]
In addition, since the voice mail of the voice mail center 7 is periodically taken into the self-operated base station 2 every predetermined time, that is, every predetermined time, the latest voice mail can always be stored in the voice mail recording / reproducing unit 20. it can.
[0074]
In the above-described first embodiment, the case where one PHS terminal 5 is connected to the private base station 2 is described, but a plurality of PHS terminals 5 may be connected. As this example, the case of the self-supporting base station 4 and the PHS terminal 5 provided in the office (company) area can be considered. In this case, the voice mail recording / reproducing unit 20 of the private base station 4 stores the voice mail in association with the above-described PS (PHS terminal) telephone number and the PIN number of the PHS terminal. , Only the corresponding voicemail can be played and heard.
[0075]
(Second Embodiment)
A second embodiment of the present invention will be described below with reference to the drawings.
However, it is assumed that the schematic configuration of the radio communication system to which the present invention is applied is the same as that of FIG. 1 and the schematic configuration of the base station applied to such a radio communication system is the same as that of FIG. The same parts are denoted by the same reference numerals, and illustration and description thereof are omitted.
[0076]
Further, FIG. 10 shows a schematic configuration of the PHS terminal 5, but since the main configuration is as shown in FIG. 3, the same parts are denoted by the same reference numerals, and the description thereof is also omitted. .
[0077]
Then, a voice mail recording / reproducing unit 42 is further connected to the terminal 5. The voice mail recording / reproducing unit 42 is activated by an access signal to the voice mail center 7 output from the control unit 37, records voice mail sent from the voice mail center 7 via the base station, and The recorded voice mail can be read in accordance with a key operation at the key input unit 40.
