Abstract

PURPOSE:To call lots of receivers in a shorter time by setting a transmission code comprising of the number as a reference of a serial number and several data when a consecutive call number is in existence. CONSTITUTION:A call number transmission means 1 sends a call number corresponding to a receiver to be called to a transmission data buildup means 2, a mode switching means 3 and a storage means 4. The call number is stored in the storage means 4 and the mode changeover means 3 discriminates whether the sent call number is a number adjacent to the call number stored in the storage means 4 and uses either a start or an end call number of a serial number as a reference call number when the number is adjacent and calculates several data to send it to the transmission data buildup means 2. The transmission data buildup means 2 combines the sent reference call number and several data to build up the transmission signal and sends the result to a transmission section. Through the constitution above, a cyclic transmission code being a set of individual call codes is compressed to call lots of receivers in a shorter time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio paging system for paging a specific person used in a small zone.

[Summary of the invention]

The present invention relates to a communication method for an individual radio selective calling system used when calling a specific individual from among a large number of people at a counter in a bank, hospital, etc. If there are consecutive calling numbers, by setting a transmission code consisting of a reference number for the consecutive numbers and number data indicating the number of calls, the numbers are sequentially arranged in chronological order and repeated. It is possible to compress the circular transmission code, which is a collection of individual calling codes transmitted by the system, and to make it possible to call a large number of receiving devices in a shorter time.

[Conventional technology]

In the communication method of the conventional individual radio selective calling system,
When calling multiple receiving devices, calling a collection of individual calling codes (hereinafter referred to as individual calling codes) that include the individual calling numbers of the receiving devices required from the transmitting device are arranged in chronological order. A code (hereinafter referred to as a circular transmission code) is repeatedly transmitted in a circular manner to call a plurality of required receiving devices.

[Problem to be solved by the invention]

In the above communication method, individual calling codes correspond one-to-one to each receiving device, so when calling many receiving devices at the same time, it is necessary to send a large number of individual calling codes in a circular manner, The disadvantage is that it takes a long time to send the individual call code.

[Means to solve the problem]

In order to solve the above problems, in the present invention, when there are numbers called consecutively in a circular transmission code,
Either the first calling number of the consecutive numbers (hereinafter referred to as the lower limit calling number) or the last calling number of the consecutive numbers (hereinafter referred to as the upper limit calling number) is the standard calling number, and the lower limit calling number is set as the reference calling number. As the number data of the calling number from the number to the upper limit calling number, one calling code (hereinafter referred to as range calling code) consisting of the standard calling number and number data
By setting as , all calling numbers consecutively existing within the range of the lower limit calling number and the upper limit calling number can be called by transmitting the range calling code.

[Effect]

If an individual call code exists with consecutive numbers in the cyclic transmission code transmitted from the transmitter with the above configuration, the individual call code is deleted from the cyclic transmission code, and a range call code is set in its place. . Therefore, in a system where there are many receiving devices having individual calling codes with serial numbers, the circular transmission code is compressed, and therefore, it becomes possible to call a large number of receiving devices in a shorter time.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1A is a functional block diagram of a transmitter to which an embodiment of the present invention is applied.

The calling number sending means 1 transmits a calling number unique to the receiver corresponding to the receiver to be called, the data construction means 2.mode switching means 3. It is sent to the storage means 4. The calling number is stored in the storage means 4, and the mode switching means 3 determines whether the sent calling number is adjacent to the calling number stored in the storage means 4, and if so, Switch the mode to range calling mode, or to individual calling mode if they are not adjacent. In the case of range calling mode, there are consecutive calling numbers, but the numerical data is calculated as the lower limit calling number which is the first calling number of the consecutive numbers or the upper limit calling number which is the ending calling number and the reference calling number. . (Hereafter, as an example, in range call mode, the lower limit call number will be explained as the standard call number) In the case of individual call mode, the sent call number will be the standard call number, and the number data will be set to "1". , the mode switching means 3, as described above,
The mode is switched in accordance with the sent calling number, and the standard calling number and number data are sent to the transmission data construction means 2. The transmission data construction means 2 constructs a transmission signal by combining the reference call number and number data sent from the mode switching means 3, and sends it to the transmission section.

FIG. 1B is a functional block diagram of a receiver to which an embodiment of the present invention is applied. The transmitted signal detected by the receiving section is transmitted to mode determining means 6. The data is sent to the data comparing means 7.

The mode determining means 6 takes in numerical data included in the received signal, determines whether it is an individual call code or a range calling mode based on the numerical data, and sends the result to the data comparing means 7 as information. The data comparison means 7 compares the unique calling number registered by the calling number registration means 9 and stored in the calling number storage means 8 with the calling number sent from the receiving section. First, in the case of the individual means mode based on the information from the mode discrimination means 6, if the received calling number and the internally stored calling number match, a detection signal is sent to the notification unit 10. Next, the range calling mode is selected. In this case, if the internally stored calling number is included in the calling number range consisting of the received calling number and the number data following it, a detection signal is sent to the notification unit IO.

FIG. 2 is a data configuration diagram of a transmission signal to which an embodiment of the present invention is applied. Transmission signal a-1+a-t..., 1
is the synchronized data 21. ID data 22. It consists of a calling number 23 and number data 24, each of which has a predetermined bit length. ID data 22 is the system ID, and may be set in advance in the receiver or simultaneously set at the time of registering the calling number, and includes the calling number 23 and number data 2.
4 is constructed by the transmission data construction means 2 of the transmitter, the reference call number is the call number 23, and the number data 24 is "1°" in the individual call mode and "2" in the range call mode. The number is as follows.

3A and 3B show conventional transmission signal sending routines. 1), 12, 14, and 16 shown in FIG. 0 correspond to unique calling numbers. Figure 3 A is the call number 1).
FIG. 3B shows that four receivers 12, 14, and 16 are called cyclically, and in addition to the call in FIG. 3A, call number 13 is also called. Note that when the receiver confirms that it has been called, it removes the confirmed calling number from the loop.

FIGS. 4A and 4B show a transmission signal sending routine to which an embodiment of the present invention is applied. Here, Fig. 4A
is an implementation of the present invention in the calling routine shown in FIG. 3A. Similarly, FIG. 4B is an implementation of the present invention in the calling routine shown in FIG. 3B.

Number data 42 and 44 in the data configuration diagrams shown in FIGS. 4A and 4B correspond to the individual call mode, and the number data 4
1.43 supports range call mode.

As shown in FIGS. 3A and 3B, in the conventional calling routine, it is necessary to send a calling number corresponding to each receiver, but when the embodiment of the present invention is applied, Figure 3A is the calling number 12 as shown in Figure 4A.
There is no need to send out. This is the calling number 1). 1
When calling consecutive numbers like 2, the calling number 1) is the standard calling number, and the number data is "2" as shown in 41.
This is because the number of calling numbers 12 can be reduced by doing so. In FIG. 3B, the calling numbers 1) to 14 are continuous, so in FIG. 4B to which the embodiment of the present invention is applied, the calling number 1) is the standard calling number, and the number data is " By setting the number to 4", the number of call numbers 12 to 4 can be reduced.

〔Effect of the invention〕

As explained above, this invention is capable of shortening the call response time because the transmission signal is shortened by using both individual calling using an individual calling code and range calling using a range calling code that calls within a range from a standard calling number. effective. In addition, even for receivers that have already been called, range calls in the - range are periodically performed, so even if the receiver is outside the reception area when the call is made, when the receiver enters the reception area again. This has the effect of making calls possible.
