Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pager capable of sending a message set by a user.

[0002]

2. Description of the Related Art In a pager system, when a caller (caller) makes a call to a number given to the pager, the pager is notified of this by a base station, and the pager's carrier (callee). However, it is called by a bell sound.

In addition, when the caller makes a call, when a predetermined key operation is performed on the dial key of the telephone, not only the caller but also a message can be sent. Ie R for pager
OM is provided, and in its ROM, as shown in FIG. 8A,
There is a table ROMT with 20 standard messages. The caller then calls the number given to the pager. Code "* 4 * 4" indicating that the message was sent
With the dial keys. If the message is “TEL Seyo” in the table ROMT, the message number of the message is “02”, so “02”
With the dial keys. Enter "#" indicating the end using the dial keys. Key operation.

Then, from the base station, the identification code for identifying the pager and the data "02" indicating the message number "02" input by are converted into the FSK signal and transmitted. When the pager of the carrier receives the FSK signal, it checks whether or not the identification code indicates himself, and when it indicates himself, the data "02" sent together is referred to the ROM. The data is converted into character data of "TEL-SEYO", and this character data is further converted into display data and supplied to the LCD. Therefore,
On the LCD of the pager corresponding to the number of ",""TELseyo" corresponding to the message number of "02" is displayed.

Thus, in the pager system, not only can the pager's carrier be called, but also the message of the table ROMT can be sent.

However, the standard message of the table ROMT may be insufficient or inconvenient for some users.
Therefore, in the pager system, if the user prepares an arbitrary message in advance, the message can also be sent.

That is, the pager is provided with a RAM backed up by a battery, and the RAM has a table RAMT having 15 areas as shown in FIG. 8B, for example.
Will be prepared, and "21" will be added to the 15 areas.
The message number "35" is given. Also, the message content is, for example, up to 20 digits for numbers and up to 6 letters for alphabets.

When the above key operation is performed, for example, when "21" is keyed in, data "21" indicating the message number "21" is transmitted. Then,
In the pager, the message number "2" of the table RAMT
The character data registered here is read out from the "1" area, converted into display data and supplied to the LCD.

Therefore, the message registered in the message number "21" area of the table RAMT is displayed on the LCD of the pager. That is, the user
If you prepare a message in advance, you can send it as well.

In the following description, the messages prepared by the user in the table RAMT will be generically called "unique message".

[0011]

As described above, in the pager system, the original message prepared by the user can be sent in addition to the standard message.

However, as is clear from the above,
When sharing a unique message in a group, it is necessary to prepare the same unique message for each pager of the group, and in order to do so, it is necessary to manually input the unique message for each pager. Moreover, in that case, the correspondence between the original message and the message number must be the same for all pagers.

However, such key operation is troublesome, and mistakes are likely to occur. Especially when the number of people in the group is large, it becomes a considerable work.

The present invention is intended to solve such a problem.

[0015]

Therefore, in the present invention, when the reference numerals of the respective parts correspond to the embodiments described later, the receiving circuit 11 for receiving the transmission signal from the base station,
A decoder circuit 12 for extracting a signal indicating a call from a transmission signal, means 32 and 34 for calling a carrier controlled by the signal indicating a call, a table RAMT for storing message data set by a user, and a transmitting means 40. When a predetermined key operation is performed, the data of the message set by the user is read from the table RAMT and is output to another device by the transmission means 40 to perform another predetermined key operation. At this time, the message data output from the transmitting means 40 of the other device is received by the receiving means 50 and written in the table RAMT.

[0016]

When a predetermined key operation is performed on the pager on the transmitting side and the pager on the receiving side, the message stored in the table RAMT of the pager on the transmitting side is read from the table RAMT and transmitted. Then, the transmitted message is received by the pager on the receiving side and stored in the table RAMT of the pager on the receiving side.

The same processing as in A is performed, the data of the unique message transmitted to the tables RAMT and RAMT are respectively written, and when the writing is completed, the normal standby state is restored.

In this way, the pagers 10M, 10A to 10C which need to have the same original message are prepared, and thereafter,
The data of the unique message prepared in the table RAMT of the pager 10M can be transferred or copied to the tables RAMT to RAMT of the plurality of pagers 10A to 10C at once by simply performing a simple key operation. Therefore,
It is extremely easy to prepare the same unique message for multiple pagers. In addition, in that case, there is no troublesomeness or input error caused by manual input. Also, the correspondence between the original message and the message number will not be mistaken.

Further, since it is not necessary to connect each pager with a dedicated cable, the operation is simple and the trouble that the original message cannot be transferred because the cable cannot be found can be avoided.

FIG. 4 shows the case where the unique message data is transferred by radio waves. That is, in this example, the format of the output signal S41 of the port 41 is a general binary data format, and its transmission rate is equal to the transmission rate of the data sent by the FSK signal from the base station. It is set to 1200 bps. In addition, the modulation circuit 4
The modulation format of 2 is the same as that of the base station.

When the original message of the pager 10M is sent to the pagers 10A to 10C, the pager 1
A predetermined key operation is performed on the keys 31 to 31 of 0A to 10C to set the pagers 10A to 10C in the reception mode of the unique message.

Then, a predetermined key operation is performed on the key 31 of the pager 10M to set the pager 10M in the transmission mode of the original message. Then, pager 10M
The unique message data written in the table RAMT of the RAM 23 is read out in the order of message numbers and supplied to the port 41, and the unique message data is output from the port 41 as the serial signal S41.

It is advantageous in terms of battery life and the like.

In the example shown in FIG. 5, the pager 10M for transmitting the data of the unique message and the pager 10A for receiving the data of the unique message can be transmitted / received even if they are apart from each other. That is, the port 41 is a parallel output port, and the DTMF signal forming circuit 46 is connected to the port 41, and when the forming circuit 46 outputs the DTMF signal S46,
The DTMF signal S46 is sent to the speaker 4 through the amplifier 47.
8 are supplied.

Further, a microphone 54 is provided, a signal from the microphone 54 is supplied to a DTMF signal decoder circuit 56 through an amplifier 55, and an output signal thereof is supplied to a port 53.

When the pager 10M on the transmitting side and the pager 10A on the receiving side are located apart from each other, first, a telephone call is made so that the two can be acoustically connected. On the transmitting side, the speaker 48 of the pager 10M is brought into contact with the transmitter of the telephone, and on the receiving side, the microphone 54 of the pager 10A is brought into contact with the receiver. And key 3 on pager 10A
A predetermined key operation is performed on 1 to set the pager 10A to the unique message reception mode. Also, pager 1
A predetermined key operation is performed on the 0M key 31 to set the pager 10M to the unique message transmission mode.

Then, the unique message data written in the table RAMT of the RAM 23 of the pager 10M is read in the order of the message numbers, and the forming circuit 46 controls according to the read unique message data. The forming circuit 46 responds to the data of the original message by DT.
The MF signal S46 is output.

FIG. 6 shows an example of the relationship between the characters of the unique data and the DTMF signal S46. That is, for example, when the character (numeral) is "1", the DTMF signal corresponding to the dial key "1" is output. Further, when the character is "A", the DTMF signal corresponding to the dial key "2" is continuously output twice at a predetermined interval as in the case where the "2" key is continuously pressed twice. In addition, the letter "K"
DTMF corresponding to the dial key "5" when
If the signal is like pressing the "5" key three times in a row,
It is output three times consecutively at a predetermined interval.

Further, for example, the character "A" is followed by the character "B".
If there is a problem, the DTMF corresponding to the "2" key
The signal continues with "A" and "B", which is indistinguishable from the letter "B" followed by the letter "A", so the "2" key showing the letter "A" Following the DTMF signal, the DTMF signal corresponding to the "0" key is output as the delimiter code, and then the DTMF signal of the "2" key indicating the character "B" is output.

Therefore, as a message, for example, "HUR
In the case of sending "RY UP", when this is expressed by a DTMF signal (dial key), it becomes as shown in FIG.

Thus, the forming circuit 46 sends the table
D according to the original message data read from RAMT
The TMF signal S46 is output. Then, this signal S46 is supplied to the speaker 48 through the amplifier 47 and the DTMF is supplied.
Converted into sound, this DTMF sound is sent out to the receiving side telephone through the transmitter.

Then, in the receiving side telephone, the DTMF sound sent from the transmitting side is output from the handset, and this is also transmitted to the microphone 5 of the pager 10A.
The original DTMF signal S46 is picked up when the sound is picked up at 4. Then, this signal S46 is supplied to the decoder circuit 56 through the amplifier 55 and is decoded into the original signal S41, and this signal S41 is taken in through the port 53,
It is written in the table RAMT of the RAM 23 in the order of message numbers.

Then, in the pager 10M, when all the data of the original message of the table RAMT are output,
Return to normal standby state. Also, in the pager 10A, the data of all the received unique messages is stored in the table RA.
When writing to MT, it returns to the normal standby state.

In this way, also in this example, the same unique message can be prepared extremely easily for a pager at a distant place only by performing a simple key operation.

In the above description, the original message is JI
Although it is assumed that the data is transmitted and received in the state of the S code, the code of other standards may be used, and the presence or absence of the error check bit is arbitrary. Further, in the above description, the decoder circuit 12 is configured by the microcomputer, but it may be configured by a dedicated circuit in which logic circuits are combined.

Further, among the original messages of the table RAMT,
Specify and send a specific original message, and send this to the table RAMT
It is also possible to write in the corresponding area of.
Moreover, in the example of FIG. 1, transmission and reception can be performed using an optical fiber.
