Abstract

PURPOSE:To reduce the transmission data volume to improve the transmission efficiency by transmitting a fixed form sentence code peculiar to a pager terminal to a radio call station without conversion to data as it is by a code transmission means. CONSTITUTION:When having a fixed form sentence to be sent and displayed, a calling subscriber inputs the code of the fixed form sentence in accordance with a correspondence table between fixed form sentences and codes peculiar to a pager terminal 4 to be called. When one-bit data for identification is inputted, data inputted together with this data is judged as the fixed form sentence code and this code is reported and transmitted to a radio call station 3 without conversion to data as it is by a code transmission means 20. When judging the existence of the fixed form sentence code in input reception data by the bit for discrimination, the terminal 4 uses this code as the address signal to access an IC card of a recording medium 40 and reads out and displays the fixed form sentence corresponding to this code. For example, fixed form sentence 'Please, communicate to section XX of OO company.' is displayed when the reception code is 0001.

[Industrial application field]

The present invention relates to a paging system and a pager terminal used therein, and more particularly to a paging system that wirelessly transmits messages consisting of numbers and characters to a portable receiver, and a pager terminal used therein.

With the development of smaller and more sophisticated portable receivers and the sII paging signal system, paging services have become possible from simple calls to character transmission services such as numbers, kana, and alphabets, and various message services are now required. It became so. For this reason, there has been a demand for a service that allows the use of not only fixed phrases common to all subscribers and pager terminals, but also fixed phrases unique to pager terminals.

[Conventional technology]

The paging system consists of a central 11J W li that sends out paging signals and messages based on signals input from telephone network subscribers via the exchange, and a central control station that converts the paging signals and messages into a predetermined format and transmits them wirelessly. It consists of a radio paging station and a pager terminal that receives signals from the radio paging station and displays messages.

In such a paging system, a conventional pager terminal has a configuration as shown in FIG. In the figure, 28 signals from the radio calling station received by the receiving antenna 61
The received signal in the 0 MHz band is converted into baseband data by the receiving unit 62, and then sent to the microprocessor (M
PU) unit 63. The MPU section 63 is the memory section 6
After reading and executing the program stored in the M 4 and storing the data from the receiving unit 62 in the memory unit 64, the M
PtJIJI (Access section 65 to display received data read out from memory section 64 on display section 66. This received data is a message such as numbers and letters.

Further, 67 is an operation unit and is a keypad for a reset switch, etc. 68 is a timing counter, MPL11J1
1Of! 565 (7)! Count 11,111 mink.

Note that the display section 66 can also generate a ringing tone.

[Problems to be Solved by the Invention] However, although the conventional paging systems and pager terminals described above can transmit and display fixed phrases as messages, the fixed phrases are common to all pager terminals, and the use of each pager terminal is different. It is not possible to use fixed phrases tailored to the person. Therefore, in order to display a message not specified in the standard text to the user of a pager terminal, the telephone network subscriber (caller) must create the message on a personal computer, etc. (Composing messages in a predetermined manner using a push-button dialing telephone is very complicated and cumbersome).

In addition, even when displaying predetermined fixed phrases on a pager terminal, the above fixed phrases are encoded, so when a telephone network subscriber enters the code of the desired fixed phrase, the central control station displays the code. Since the data is converted into data indicating a fixed form sentence corresponding to the data, the amount of data in the transmission system from the central M control station to the pager terminal is large, and the data transmission efficiency is not very good.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a paging system that can display original fixed text on a pager terminal with high transmission efficiency, and a pager terminal using the same.

It is characterized by having a code transmitting means 20 in the pager terminal 4, and a recording medium 40 in the pager terminal 4.

Here, when the code transmission means 20 inputs a code of a fixed phrase arbitrarily determined for each pager terminal, the code transmission means 20 transmits the code as it is to the pager terminal 4 via the focal line calling station 3.

Furthermore, the recording medium 40 has recorded therein fixed phrases unique to the pager terminal 4 in correspondence with the codes. Pager terminal 4
When receiving the above code, accesses this recording medium 40, reads out and displays a fixed phrase that matches the received code.

FIG. 1B shows a principle configuration diagram of a pager terminal according to the second aspect of the invention (hereinafter referred to as the second invention). As shown in the figure, the pager terminal of the second invention has a focal line calling station (
Received radio signal from 3) in Figure 1A i! The received data received in S41 is stored in the memory section 42. The control means 43 determines whether the received data read from the memory section 42 is a code of a fixed phrase or not, and if it is a code of a fixed phrase, the control means 43 reads the received data from the recording medium 40 based on the code of the received fixed phrase.
Reads the corresponding fixed phrase from. Further, 44 is a display section which displays the above-mentioned fixed phrase read out by the control means 43.

[Effect]

In the first invention, the code of the fixed text unique to the pager terminal 4 is directly transmitted to the radio calling station 3 by the code transmitting means 20 without being converted into data. It can be made quite small.

In addition, in the second invention, 611 from among the fixed phrases unique to the pager terminal and its codes recorded on the distribution medium 40.
