[0002]

2. Description of the Related Art Recently, a wireless paging system known as a wireless communication system is a so-called one-way communication system that only wirelessly transmits information addressed to each terminal. The office can cover a wide communication range, the pager that is the receiving terminal can be made smaller and lighter, and the usage fee is lower than car phones and mobile phones. Not only that, the number of cases where individuals use it as a convenient communication tool with friends on the go is rapidly increasing.

Conventional access means to a pager include a telephone for an individual, a company, and an operation service company, a personal computer, a service information processing company for a service information provider.

The information created by these access means is sent to the pager service company via the public line network, and the pager service company creates and sends the send information for each page number of the pager owned by the individual or the company. It The pager includes an NP (Numeric Pager) type capable of receiving numerical information and an IP (Information Pager) type capable of receiving character information.

Therefore, there is a problem in that the radio paging system does not sufficiently cope with the case where it is highly necessary to confirm the transmission of an important message or an urgent message.

Furthermore, when the sending user sends a message using a pager equipped with an auto-dialer function, the speaker that outputs the DTMF signal sound is applied to the mouthpiece of the touch-tone handset, so that the mouthpiece of that speaker is used. D due to the influence of how to apply
There is a possibility that the TMF signal sound is erroneously input and bit loss of the message data or garbled data occurs and the intended message data is not completely transmitted.

Further, in the wireless paging system, the intended message data is completely lost due to data loss or data garbled of the transmitted message data even in the process of being transmitted from the touch-tone telephone to the public line network, the communication service center and the wireless base station. Since it may not be sent to the destination pager, it is important to perform confirmation processing to confirm whether the sent message is correctly sent to the destination pager, and wireless paging has a function to enable the sent message confirmation processing. It is effective to give it to the system.

When it is set (ON), the self-call number (self ID) that is the transmission source is output as the DTMF signal by the DTMF signal generation unit 30, and then the message data is output by the DTMF signal generation unit 30 as the DTMF signal. The output message data is held in the transmission data holding register 26a.

When the decoder unit 23 detects the arrival of its own calling number transmitted from the transmitting base station 6 based on its own calling number transmitted by the transmission message confirmation mode set, the CPU 26 calls the calling. The content of the message data input from the decoder unit 23 following the number is compared with the content of the message data previously held in the transmission data holding register 26a. And CPU
26 determines the coincidence rate of the message contents based on the comparison result, and performs notification processing indicating the success or failure of message transmission by the display unit 41 and the sounding speaker 35 according to the determination result.

Under the control of the CPU 26, the display buffer 40 sequentially holds the character data input from the character generator 39, and then sequentially outputs the character data to the display unit 41 at a predetermined timing.

The display unit 41 is composed of a liquid crystal display panel, and displays the message data being created, the selected TEL memory data or message data, the received message data, etc. on the display unit 41.

Next, the operation of this embodiment will be described.

In FIG. 1, the case where transmission data is output from the pager 2 by the DTMF signal sound output to the touch-tone phone 3 and the message data is transmitted to the pagers 7, 8 and 9 will be described below.

First, the transmission data output process executed by the pager 2 will be described with reference to the flowcharts shown in FIGS.

When the power switch of the pager 2 is turned on, the incoming call waiting state is first set, and the message creation mode or the message selection mode is selected by operating the mode key to create a transmission message or a message read from the message memory 27. Is selected (step S1), the created or selected message data is held in the send data holding register 26a as send message data.

Then, a process of selecting a destination from the telephone directory table of FIG. 3 stored in the TEL memory 28 is executed (step S2).

For example, when the user operates the key input unit 25 to select "1" as the group number registered in the telephone directory table, the name in which the group number is set is the telephone directory table in FIG. As shown in FIG. 7, the group name “school friends” and the names “Taro Kimura, Kimihiko Sato, Natsuko Kojima” are displayed on the display unit 41 in association with each other.

When the group is selected as described above, the group number 1-3 selected in step S2 is selected.
The calling number corresponding to the name is read from the telephone directory table in the TEL memory 28, and the transmission data holding register 26
The telephone number for collective call stored in a is stored in the TEL memory 28.
It is selected from the telephone book table in the table and held in the transmission data holding register 26a.

Next, by operating the dialer key, the batch calling telephone number is set to D by the DTMF signal generating section 30.
After being converted into a TMF signal, the DTMF speaker 32 through the DTMF amplifier 31 transmits the collective call telephone number D to the mouthpiece of the handset of the touch-tone telephone 3.
A TMF signal sound is output (step S3).

If no group is selected in step S2, then in step S3,
A calling telephone number is selected from the telephone directory table of FIG. 3 and is held in the transmission data holding register 26a, and the calling telephone number is converted into a DTMF signal by the DTMF signal generation unit 30 and passed through the DTMF amplifier 31. DTMF
The speaker 32 outputs the DTMF signal sound of the calling telephone number to the mouthpiece of the handset of the touch-tone phone 3.

Next, after outputting the DTMF signal sound of the telephone number for collective call, after the line between the touch-tone telephone 3 and the communication service center 5 is connected via the public line network 4 (step S4), the dialer key is again used. When you operate
The calling numbers of the three names previously held in the transmission data holding register 26a are sequentially converted into DTMF signals by the DTMF signal generating section 30 via the dialer buffer 29, and D
DTMF speaker 32 via TMF amplifier 31
Thus, the DTMF signal sound of each calling number is sequentially output to the mouthpiece of the handset of the touch-tone phone 3 (step S5).

Next, the CPU 26 determines whether or not the message confirmation mode is set (ON) (step S6). If the message confirmation mode is not set, the process proceeds to step S10 and the message confirmation mode is set. If it is set, the calling number of its own, which is the transmission source, is read and held in the transmission data holding register 26a.

Then, this calling number is sent to DT by the DTMF signal generator 30 via the dialer buffer 29.
After being converted into an MF signal, the DTMF speaker 32 through the DTMF amplifier 31 causes the DTMF of the transmission source calling number to the mouthpiece of the handset of the touch-tone phone 3.
A signal sound is output (step S7).

Next, the message data created or selected in step S1 and held in the transmission data holding register 26a is converted into a DTMF signal by the DTMF signal generator 30 via the dialer buffer 29, and the DTMF amplifier 31 is supplied. The DTMF speaker 32 outputs the DTMF signal sound of the message data to the mouthpiece of the handset of the touch-tone phone 3 via the DTMF speaker 32 (step S8).

If the message confirmation mode is not set in step S6, the message data created or selected in step S1 and held in the transmission data holding register 26a is the same as in step S1.
At 0, the DTMF signal is converted into a DTMF signal by the DTMF signal generator 30 via the dialer buffer 29, and the DTMF speaker 32 via the DTMF amplifier 31 sends the DTMF signal of the message data to the mouthpiece of the handset of the touch-tone phone 3. After the sound is output, the transmission data held in the transmission data holding register 26a is discarded,
This processing ends.

Through the above processing, the pager 2 can perform DT
The destination call number output by the MF signal tone, the own call number, and the message data are transmitted from the touch-tone telephone 3 to the communication service center 5 via the public line network 4 by the DTMF signal tone.

In the communication service center 5, when the message confirmation mode is set in the pager 2 which is the transmission source, the group call is selected in the pagers 2, 7, 8 and 9 and the touchtone phone 3 is selected.
First, as shown in FIG. 8 (a), from the calling number of the destination, the calling number of itself and the message data transmitted from
Pager ID of each group (n = 1, 2 ...)
Is added with the same temporary ID to generate the address frame of the first cycle.

Then, following the first cycle address frame shown in FIG. 8A, the message data transmitted from the touch-tone phone 3 is added to the same temporary ID as shown in FIG. 8B. The message frame of the second cycle is generated.

Then, each of the generated transmission frames of the first cycle and the second cycle is sequentially transmitted from the communication service center 5 to the transmission base station 6 via the line.

Then, in the transmission base station 6, the transmission frames of the first cycle and the second cycle, which are sequentially transmitted from the communication service center 5, are the pager 7, which is the transmission destination.
8 and 9 and the pager 2 which is the transmission source are simultaneously wirelessly transmitted.

Returning to the flow of FIG. 5, after the message data is output in step S8, the reception waiting timer in the CPU 26 starts counting (step S9). That is, from the communication service center 5 to the transmitting base station 6
The address frame of the first cycle and the message frame of the second cycle transmitted to the pager 7, 8 and 9 which are the transmission destinations and the pager 2 which is the transmission source are simultaneously wirelessly transmitted to The counting of the waiting time of 4 minutes until the call arrives at itself is started.

Then, the process proceeds to step S11 in FIG.
In step S11, the presence or absence of the arrival of the first cycle address frame and the second cycle message frame transmitted from the transmission base station 6 is detected. That is, first, the pager 2, which is the transmission source, detects whether or not the pager ID of its own set in the address frame of the first cycle is received. A temporary ID is set in the register in the decoder unit 23.

Then, the temporary ID set in the subsequently received second cycle message frame
And the decoder unit 23 upon receipt of the previous address frame.
Only when the coincidence with the temporary ID set in the register inside is confirmed, the subsequently received message data is input to the CPU 26.

Then, in the pager 2 which is the transmission source,
Contents of this received message data and step S1
Then, the contents of the message data held in the transmission data holding register 26a are compared with each other, the matching rate of the message contents is determined, and the process corresponding to the matching rate is performed (step S12). If the matching rate is less than 80%, it is determined that the received message is unrelated to the output outgoing message, and the non-confirmation message is displayed on the display unit 41 (step S13).
Returning to the message arrival detection process of, the message arrival process is repeated.

At this time, since the received message is stored in the message memory 27, the received message can be called later and displayed on the display unit 41 for confirmation.

Further, the matching rate of the message data contents is 8
In the case of 0% <match rate <99%, the received message data is output message data that has been output, but it is determined that the content of the message message has been erroneously transmitted, and erroneous data transmission alert processing is performed. , "Data has not been correctly sent" is displayed on the display unit 41, an alert sound is issued by the sound speaker 35, and the received message data is discarded (step S14).

After that, when the dialer key is operated, the processing from step S3 onward is executed based on the transmission data held in the transmission data holding register 26a. At this time, the received message data may be displayed on the display unit 41. This allows the sender user to know what kind of error message data was sent to the other party.

That is, in this case, the message data output from the pager 2 of the transmission source is transmitted from the touch-tone telephone 3, the public line network 4 and the communication service center 5 to the transmission base station 6, and the message data bit is missing. It is judged that there are many garbled data.

Further, the matching rate of the message data contents is 1
In the case of 00%, it is determined that the received message data and the transmitted message data have the same content, that is, the output transmitted message data is the same as that of the touch-tone phone 3.
In the process of being transmitted from the mouthpiece, the public line network 4 and the communication service center 5 to the transmitting base station 6, it is determined that the output message data was transmitted without any bit loss or data garbled.

Then, the received message data held in the CPU 26 and the send data held in the send data holding register 26a in the CPU 26 are discarded (step S15), and a message indicating that the message data has been correctly sent is displayed. While being displayed on the display unit 41, the notification speaker 35 or the LED 38 gives a notification sound or a flashing notification different from the normal notification (step S16).

Next, in step S11, if no message arrival is detected, it is checked whether the reception waiting timer that started counting in step S9 has passed 4 minutes (step S17), and 4 minutes have passed. If not, the process returns to step S11 to repeat the message arrival detection process, and if 4 minutes have passed, the missed reception alert process is performed, and for example, the display unit 4
In addition to displaying "Could not receive confirmation message" in 1, alert sound is issued by the sound speaker 35 (step S18), the reception waiting timer is reset (step S19), and then the dialer key is operated. Then, the process returns to step S3 in FIG. 5 and the processes from the output process of the batch transmission call number are repeatedly executed.

FIG. 9 shows a display example of the message data collectively transmitted from the transmission base station 6 to the destination pagers 7, 8 and 9 by the above transmission data output processing.

In the display example of FIG. 9, the address frame of the first cycle transmitted from the transmitting base station 6 is first received by the pagers 7, 8 and 9 of the transmission destination, similarly to the order of arrival in the pager 2. , The temporary ID set in the address frame is set in the register in the decoder unit 23, and after the match with the temporary ID set in the subsequently received second cycle message frame is detected, the message Data is displayed on display 4
It is displayed in 1.

As described above, in the wireless paging system 1 of the present embodiment, the pager with auto dialer function 2, 7, 8 and 9 is provided with the message confirmation mode so that the DTMF signal sound of the call destination number is transmitted.
