CONSTITUTION:The system is provided with a coder 2-2 receiving a calling telephone number and succeeding message information entered from a subscriber terminal equipment and coding an individual call signal and a message signal by a predetermined coding system, with transmitters 11,12 modulating and sending the coded signal as a radio signal, and a central processing unit 2-3 controlling the coder 2-2 and has a function of inserting a predetermined symbol to a digit location of the telephone number decided in advance in the entered message information.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective calling system, and more particularly to a transmission message processing for providing information that is easy for a user to see by adding information to a message transmitted from a telephone terminal at a base station side and transmitting the message. The present invention relates to a radio selective calling method having a function.

[0002]

2. Description of the Related Art At present, in the radio selective calling system,
A receiver with a display is widely used, which not only informs the call by ringing, but also sends a message signal such as the telephone number of the caller to the individual call number and displays it on the display attached to the receiver terminal. ing. In particular,
Since the message is composed only of a combination of the numbers from 0 to 9 and some symbols, the message can be easily transmitted from an ordinary telephone terminal. Further, since the content of the message is limited to a telephone number or the like and has a length of about 10 to 20 characters, the advantage is that the air time is not so long, and it is most widely used.

A device configuration of such a conventional radio selective calling system will be described with reference to the conceptual diagram of FIG.

In FIG. 6, the telephone number assigned by the radio selective call receiver is dialed from the telephone terminal 1-1 to make a call. In the exchange period 1-2, it recognizes that the dialed telephone number is assigned to the radio selective call receiver and connects to the paging terminal 1-3. Telephone terminal 1 from paging terminal 1-3
Answer-back to -1, prompting for message input. The message information is dialed from the telephone terminal accordingly. Here, it is assumed that the number string “0123456789” is input as the message information. This message information is sent to the paging terminal 1-3 via the exchange 1-2, encoded together with the individual calling number corresponding to the telephone number assigned to the radio selective calling receiver, and the transmitters 1-4 to 1-6. Was transmitted as a wireless signal through the.

[0005]

In the above-described radio selective calling method, for example, when the telephone number 012-345-6789 is to be transmitted as a message, a signal corresponding to "-" is inserted after 2 and 5, respectively. There must be. However, this input operation is input from the keyboard if it is from a dedicated input terminal, and there are few mistakes, but if it is from a telephone terminal, for example, "*" +
A special input operation such as "2" is required. Such an operation is not only troublesome, but also causes an erroneous input. On the other hand, in the above example, "-"
If you send without adding "," it becomes easier for the sender to enter, but since the received message is displayed without the "-", the receiver carrier displays "0123456789", making it difficult to read as a telephone number. There was a drawback.

[0006]

In the radio selective calling system of the present invention, a calling telephone number inputted from a subscriber terminal and message information following it are inputted, and an individual calling signal and a message signal are predetermined codes. An encoding device for encoding by an encoding method, a transmitting device for modulating the encoded signal and transmitting it as a radio signal, and a central processing unit for controlling the encoding device, and for the input message information It has a function of inserting a predetermined symbol into a predetermined digit position of a telephone number.

[0007]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
The embodiment shown in FIG. 1 is a block diagram of a paging terminal and a transmitter portion, which are main parts shown in FIG. That is, in the paging terminal 10, the telephone number of the callee input from the telephone terminal via the exchange is stored in the temporary transmission queue 2-1. The central processing unit 2-3 is a subscriber file 2-
4, the telephone number of the callee is converted into an individual call number to be actually transmitted by radio. Furthermore, the message information is added to this and sent to the encoding device 2-2 for encoding. FIG. 2 shows a typical POCSAG system as a coding system used in the selective calling system. Furthermore, Figure 3 shows POCS
The code | symbol by the AG system is shown. The encoded data is sent to each of the transmitters 11 and 12, but each broadcaster 1
1 and 12 perform phase compensation between respective devices by the phase compensating circuit 2-5 for simultaneous transmission of multiple stations, frequency-modulate by the modulating circuit 2-6, and then radio frequency by the frequency converting circuit 2-7. And is transmitted from the antenna 2-9 via the power amplifier (PA) 2-8. In the present embodiment, the message signal input from the telephone terminal is the information "01
23456789 ", while the one transmitted by the transmitter is" 012-345-6789 ".
"-" Are inserted. The central processing unit 2-3 edits such a message signal and provides information that is easy to see as a telephone number, for example.

Next, the specific editing of the above-mentioned message information will be described in detail with reference to FIG. When you receive the telephone number and message information corresponding to the individual calling number,
Whether or not the function of this embodiment is applied is determined by the calling number. Whether or not this function is applied to each call number is stored in the subscriber file 2-4. If it is a calling number to which this function is applied, the pointer is moved to the lowest digit of the message and the digit number counter N is reset to zero.
Next, the data A indicating which digit "-" is to be inserted is set. It is determined whether or not there is a character in the upper digit of the digit currently pointed to by the pointer, and if there is, the pointer is shifted to the upper digit and the digit counter is incremented by one. If this counter N matches the designated digit number A, "-" is inserted in the message. In this example, first, A = 4 is set, and once "-" is inserted, A = 3 is set. In this embodiment, whether or not this function is applied is determined by the individual call number, but it is also possible to provide a determination bit at the beginning of the message information. For example, as shown in FIG. 5, "* 2" is dialed from the telephone terminal as information to be used for determining whether to apply this function, and subsequently, "0123456789" is input. In the central processing unit 2-3 of the paging terminal 10, the leading "* 2"
The application of this function is judged by the
Insert. Furthermore, as a method of displaying the telephone number,
It is common to use "()" in addition to "-" insertion, but changing to such a display can be easily implemented. In the case of the United States where the telephone number system (the number of digits of the city code and the number of the city code) is unified, this embodiment can be adopted as it is, but when the number system differs depending on the region such as Japan. Has a table of the area code in the subscriber file 2-4 so that the "-" insertion position can be determined.

[0010]

As described above, according to the present invention, a code such as "-", which serves as a delimiter of numbers, is automatically inserted into message information of only numbers transmitted from a telephone terminal. Is a simple transmission method, and is effective in providing a display that is easy for the receiver wearer to see.
