Is a switching center, 3 is a pager base station, and 4 is a pager terminal device carried by a called party.

The registered caller uses the general public telephone line 1 to access the pager base station 3. The pager base station 3 gives an instruction of a calling procedure to the calling party according to a predetermined program, and the calling party first stores the pager terminal device carried by the intended called party according to this instruction. The call code of the calling party is input using a push button or the like on the telephone. Then, in the same manner as above, a message to be sent to the called party is input. The pager base station 3 wirelessly transmits the calling code and message received from the caller in a predetermined communication format.

The message information is generally designated by a push button while the caller looks at the conversion table equivalent to the fixed text code / character string conversion table stored and stored in the control computer of the pager base station 3, and the desired message is displayed. Is wirelessly transmitted from the pager base station 3.

The schematic configuration of an example of such a communication format is described in Section 6.
Shown in the figure. In the figure, "SYNC" indicates a synchronization signal bit string, "ADDRESS" indicates the calling code, and "MESSAGE" indicates a transmission message from the caller.

[Problems to be Solved by the Invention] In a conventional pager system, it is possible to reduce the number of key operation steps, but the amount of data is increased because the data converted into a character string is sent to the pager radio wave. In addition to traffic, it is necessary to limit the amount of data from the viewpoint of traffic, and since a raw character string is simply put on the radio wave that anyone can intercept, confidentiality cannot be maintained. Also,
Since the fixed form code / character string conversion table is stored and stored in the computer of the pager base station, it takes time to create this fixed form code / character string conversion table, and it is not possible to have a separate conversion table for each subscriber. It was virtually impossible to deal with. Furthermore, the call-out operation is not only complicated, but a call-dedicated terminal is required.

It is an object of the present invention to provide a pager terminal device capable of reducing the amount of transmitted data and the number of key operations and at the same time maintaining confidentiality for each user and capable of calling and receiving operations.

[Means for Solving the Problems] In order to achieve the above object, the invention according to claim 1 is
A memory card in which a message code and message information included in a transmission signal transmitted from a pager base station are stored in correspondence with each other, a reading unit that reads out the message code and the message information stored in the memory card, and the reading unit. Display means for displaying the message code and message information read by the reading means, and operation means for selecting the message code and message information read by the reading means, wherein the display means includes the message code selected by the operating means. The message information and the message information are displayed in association with each other.

According to a second aspect of the present invention, a storage means for storing a unique call code, a receiving means for receiving a transmission signal transmitted from the pager base station, and a transmission signal received by the receiving means are stored in the storage means. The read-out means includes detection means for detecting whether the called code is included, and extraction means for extracting a message code included in the transmission signal received by the reception means based on the detection result of the detection means. Message information corresponding to the message code extracted by the extracting means is read from the memory card, and the display means displays the message information read by the reading means.

[Operation] Therefore, according to the present invention, the message code and the message information read from the memory card by the reading means are displayed on the display means in a corresponding state. And
By selecting the message code and the message information displayed on the display means by the operation means, the user can easily confirm the message code corresponding to the desired message information.

Also, when the transmission signal transmitted from the pager base station is received by the reception means and the detection means detects that the call code included in the received signal matches the call code stored in the storage means, the extraction is performed. The means extracts the message code contained in the received signal, and the reading means reads the message information corresponding to the extracted message code from the memory card,
By displaying the message information read from the memory card by the display means, the message information corresponding to the message code transmitted by the calling party can be displayed.

It is like 1 and can store 100 kinds of messages from 0 to 99 with two digit numbers.

The specific operation of the pager system according to the present invention will be described below with reference to FIGS.

Initialization When the pager system according to the present invention is used, first, a predetermined message code between the calling party and the called party and a message corresponding to the predetermined message code are converted into a standard sentence code / character string conversion table 9 of the pager terminal device. Must be set to. First, the operator uses the numeric code input keys and the character code input keys (not shown) of the input means 12 to display the values shown in Table 1 above under the control of the control means 11 according to a program stored in advance in the ROM 13. The messages corresponding to the message codes are sequentially stored in the fixed phrase code / character string conversion table 9. The standard sentence code / character string conversion table shown in Table 1 is also possessed by the caller.

Although the above-mentioned initial setting has been described with reference to FIG. 2, this setting is the same in the other embodiments shown in FIG. 3, and the input means 39, ROM 38 and control means 37 in FIG. Then, the message code shown in Table-1 and the message corresponding to the message code are stored in the fixed text code / character string conversion table 35. The standard sentence code / character string conversion table 35 shown in the figure uses a memory card that can be attached to and detached from the device. The memory card created as described above can also be duplicated and used with a personal computer, electronic notebook, etc. Becomes

Transmission / Reception Operation When the above-mentioned preparation is completed and the user wants to send a message (call) to the other party who possesses the pager terminal device, the calling party first uses the general subscriber telephone via the public line as in the conventional case.
The pager base station is called and the pager base station is notified of the desired calling number and message code under the instruction.

In the terminal device shown in FIG. 3, the calling number and the message code of the desired called party are first read from the fixed sentence code / character string conversion table 35 by the input means 39 under the control of the control means 37, and the display means 36 is displayed. , And confirm that the displayed content is the desired content, and by operating the transmission instruction key provided in the input means 39, the calling number and the message code are temporarily stored in the transmission buffer means 43. It is stored and sent by the transmission control means 44 to the public line via the speaker driving means 45, the speaker 41 and the handset.

The sending control means 44 generates a signal equivalent to operating the push button of the telephone. The pager base station which has received this notification wirelessly transmits the transmission data in the data format as shown in FIG. The pager terminal device which has received this transmission data by the reception means 5 (31) first detects by the detection means 6 (32) whether or not the calling number of the pager terminal device is included in the transmitted transmission data, and if If the calling number is included, the fixed message code / character string conversion table 9 (35) is referred to based on the code extracted from the message code in the transmission data by the extraction means 8 (34), and a predetermined message is displayed. It is extracted and displayed on the display means 10 (36).
Further, when the detection means 6 (32) detects the corresponding calling number, the control means 11 (37) drives the speaker 15 (41) to notify that there is an incoming call.

In addition, in the above embodiment, the fixed form code / character string conversion table is written in a rewritable memory (random access memory), but the present invention is not limited to the embodiment. It is needless to say that the utilization effect of the present invention can be further improved by using a memory card or the like that is widely used in (1) and the like and making it removable from the device.

[Advantages of the Invention] As described above, according to the present invention, since message information can be transmitted with a message code uniquely determined in advance on the calling side and the called side, confidentiality against radio wave interception can be maintained. In addition to being possible, since the code information is transmitted, it is possible to reduce the amount of data carried on the radio wave, and accordingly increase the number of subscribers that can be accommodated in the same radio wave.

Moreover, since the message code and the message information are stored in the memory card in association with each other, it is possible to extremely easily set and change the comparison between the message code and the message information on the calling side and the called side. Therefore, for example, by providing a plurality of memory cards having different contrast settings, a memory for storing the message code and the message information by changing the memory card to be mounted on the calling side according to the destination party. It is possible to reliably transmit desired message information to each of a plurality of called parties who have different contrast settings without increasing the memory capacity.

Furthermore, by changing the memory card to be mounted on the called side for each day of the week or for each time zone, it is possible to receive more message information without increasing the data amount of the message code. It is possible to expand the purpose of use, that is, selectively use it for work and for private use.
