Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dialer having a function of sending a message to a pager.

[0002]

2. Description of the Related Art In a pager system, when a caller (caller) makes a call to a number assigned to a pager, the pager is notified of this by an operator (base station), and a carrier of the pager ( Callee) is called by a bell sound or the like.

In addition, some pager systems allow not only a caller to call but also a message when calling.

However, when sending a message to a pager,
The message must be entered by operating the dial keys on the telephone. However, for the dial keys, "1"
Since there are only "0", "*", and "#" keys, when inputting a message, each character of the message is coded into a number of digits, and this is manually input. Therefore, the sender (caller) of the message needs to have a conversion table of the characters and the numerical codes and input the message while checking the conversion table.

However, such work is difficult, takes a lot of time, and is prone to error. For this reason,
There is a method of converting a message into a numeric code by using a personal computer and conversion software and sending the conversion result to an operator through a modem. However, in this case, a personal computer and a modem must be prepared at all times, and there is not much problem when sending a message from the office, but it is not practical when sending a message from outside. .

Therefore, there is a pager system in which an appropriate message can be selected and sent from a plurality of messages prepared in advance. That is, in this case, the pager is provided with a ROM, and as shown in FIG. 5A, a table FIXTBL having 20 types of standard messages is prepared in the ROM. The message number and the content of the message in this table FIXTBL are specified or prescribed by the operator.

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 FIXTBL, the message number of the message is "02", so "0
2 "is input from the dial keys. Enter "#" indicating the end using the dial keys. Key operation.

Then, the identification code for identifying the pager from the operator and the message number "0" input by
The data "02" indicating "2" is converted into the FSK signal and transmitted. And the pager of the carrier is the FSK
When the signal is received, it is checked whether or not the identification code indicates oneself, and when it indicates oneself, the data "02" sent together is referred to the "TE" by referring to the ROM.
It is converted into character data of "L-Syo", 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, "TEL" is displayed corresponding to the message number "02".

Thus, some pager systems not only call the pager carrier,
The message of table FIXTBL can be sent.

However, the fixed message of the table FIXTBL may be insufficient or inconvenient for some users. Therefore, if the user prepares an arbitrary message in advance, the user can also send the message.

That is, the pager is provided with a battery-backed RAM, and the RAM has a table USRT having 15 areas as shown in FIG. 5B, for example.
BL will be prepared and "21" will be displayed in the 15 areas.
A message number of "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 table USRTBL
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 USRTBL is displayed on the LCD of the pager. That is, the user has table US
If you prepare a message in RTBL in advance, you can also send it.

However, when a desired message is selected from the plurality of messages, if the number of prepared messages is large, it takes time to select the desired message, and conversely, the number of messages is increased. If you reduce the number of messages, the selection of messages will be easier, but there will be cases where there is no suitable message.

[0015]

As described above, when sending an arbitrary message to the pager, the method of inputting the character as the message becomes a problem. Moreover, when selecting a desired message from the messages prepared in advance and sending it, it takes a lot of time to select a desired message, or conversely, there is no appropriate message.

In view of the above points, the present invention is
This is to give a message sending function to the auto dialer and to easily send a necessary message.

[0017]

Therefore, in the present invention, when the reference numerals of the respective parts correspond to the embodiments described later, the dial key 46D and the DTMF signal forming circuit 4 are provided.
4, a speaker 45 to which the DTMF signal output from the forming circuit 44 is supplied, a first table having data such as a name for identifying the other party, and data of the telephone number or pager number, and a pager. The second table TXTBL that stores the data of the message to be transmitted and the third table TXTBL whose data area corresponds to each key of the dial keys 46D are provided. In the first operation mode, the other party is specified. At this time, the data of the telephone number or pager number corresponding to the other party is fetched from the first table, the fetched data is supplied to the forming circuit 44 and converted into the DTMF signal, and this DT
The MF signal is supplied to the speaker 45, and in the second operation mode, when the dial key 46D is operated, the third
Of the message data stored in the second table TXTBL, the message data corresponding to the operated dial key 46D is extracted, and the extracted message data is formed. It is supplied to the circuit 44 and converted into a DTMF signal, and the DTMF signal is supplied to the speaker 45.

[0018]

The message is registered in each of the dial keys 46D, and when the dial key 46D is pressed, the message registered in the key is selected for transmission.

It is copied from FIXTBL and registered. The following is repeated. In this way, by performing the key operation of ~, an arbitrary message (and its message number) among the messages prepared in the tables FIXTBL and USRTBL is registered in the arbitrary area of the table TXTBL.
In addition, in reality, this registration is done in the table FIXTBL, USRTBL
Of the above messages, the most frequently used messages will be performed.

<Preparation of message to be sent> This is a table
This is the case of using the TXTBL message to prepare a message for calling the carrier. Here, as an example,
The message when calling is "TEL
Sayo 03-5448-3111 Suzuki ".

That is, in this case, the function key 46F is pressed several times to set the message edit mode. As shown in FIG. 4B, the call key 46C is pressed. Then, the table TXTBL is pressed with the dial key 46D.
The message can be selected. Since "TEL SEIYO" is registered in the first area of the table TXTBL and this area corresponds to the "1" key of the dial key 46D, it is "1".
Press the key. Then, of the areas of table TXTBL,
From the corresponding area of the “1” key, the data of “TEL seyo” registered here is taken out, and this data is supplied to the display controller 36. Therefore, “TEL” is displayed on the LCD 47. At this time, in the area of the table TXTBL, "TE
The first pointer is set in the data area of “L-Syo”. After that, is repeated. That is, (1) The call key 46C is pressed. Then, the message on the table TXTBL can be selected by the dial key 46D. (2) “03-5448-3111” is the table TXTBL
In addition to being registered in the fifth area of, the area corresponds to the "5" key of the dial key 46D, so the "5" key is pressed. Then, of the areas of the table TXTBL, the data of “03-5448-3111” registered here is taken out from the area corresponding to the “5” key, and this data is supplied to the display controller 36. Therefore, the LCD 47
Following "TEL Seyo", "03-5448-3111"
Is displayed. At this time, the second pointer is set in the area of the data “03-5448-3111” in the area of the table TXTBL. (3) Press the call key 46C. Then, the message on the table TXTBL can be selected by the dial key 46D. (4) "Suzuki" is registered in the fourth area of the table TXTBL, and this area corresponds to the "4" key of the dial key 46D, so press the "4" key. Then, of the areas of table TXTBL,
The data of "Suzuki" registered here is taken out from the area corresponding to the "4" key, and this data is supplied to the display controller 36. Therefore,
On the LCD 47, "Suzuki" is displayed after "03-5448-3111". Also, at this time, the table
The third pointer is set in the area of the "Suzuki" data in the TXTBL area. In this case, since all the messages at the time of calling have been gathered, the registration key 46R is finally pressed. Then, ~
The first to third pointers set in step 3 are saved in the RAM 23. Then, the preparation of the message to be transmitted is completed.

In this way, by performing the key operation of ~, an arbitrary message (and its message number) is selected from the messages prepared in the table TXTBL. In addition,
The number of messages to be selected is arbitrary within the range of the number of message characters that can be transmitted to the pager. The order is also arbitrary.

<Transmission of Prepared Message> This is a case where the message prepared by the above-described “Preparation of message to be transmitted” is transmitted to the called pager. The pager called at this time may be a general pager as long as it has a character display capability.

That is, in this case, the function key 46F is pressed several times to set the prepared message transmission mode by <preparation of message to be transmitted>. When the pager is called and the message can be transmitted, the transmission key 46T is pressed. Then, among the areas of the table TXTBL, from the areas indicated by the first to third pointers saved in the RAM 23, the message data “TEL seyo”, “03-
"5448-3111" and "Suzuki" are sequentially read. That is, of the areas of the table TXTBL, from the area indicated by the first to nth pointers set by <preparation of message to be transmitted>, message data registered in that area is read in the order of the pointers. .

Then, the read message data is supplied to the DTMF signal forming circuit 44 through the port 33, and each character of the data is converted into a DTMF signal when the character is input from the dial key. , The DTMF signal is supplied to the speaker 45, and the speaker 45
Outputs a DTMF sound when each character of the message is input from the dial keys.

The DTMF sound is supplied to the transmitter and the DTMF signal is supplied to the operator through the telephone line. Therefore, the message prepared by <Preparation of message to be transmitted> can be sent to the pager of the carrier. it can.

<Summary> According to this dialer / pager, messages frequently used are stored in the table TX of the memory 24.
While registering in the TBL and assigning "1" to "0", "*", and "#" of the dial keys 46D to each message, those messages can be easily done with one touch, that is, easily. And, it can be prepared and sent in a short time. Also, since the messages prepared in the table TXTBL can be combined and sent, more appropriate messages can be sent.

Moreover, since it is not necessary to input the characters of the message one by one, the characters are not mistaken. In addition, 20 kinds of messages prepared in the table FIXTBL and the table
Since you can select any message from the 30 types of messages prepared in the USRTBL and register it in the table TXTBL, you have a high degree of freedom in transmitting messages.

Further, since the messages prepared in the tables FIXTBL and USRTBL can be transmitted by the conventional method, the degree of freedom of the messages that can be transmitted is great also from this point. Furthermore, it is not necessary to prepare a list of messages and message numbers.

In the above description, the transmission table TXTBL
In, register only the message numbers of the tables FIXTBL and USRTBL, and when <Preparing a message to send>, store only the message numbers of the messages to send in order instead of setting the pointer, and send the message. At times, it is also possible to extract message data from the tables FIXTBL and USRTBL and convert it into a DTMF signal according to the stored message number.
