Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a selective calling system with a display that performs selective calling using a selective calling signal and also conveys a message.

[Conventional technology]

In the conventional selective calling system with display, each of a plurality of selective call receiving devices with display stores a unique self-number, and the call signal specifies the self-number of the selective call receiving device with display that is to perform selective calling. Are known. Then, the selective call receiving device with display that receives the selective call receives the message signal following the call signal, sounds the buzzer, and displays the message on the display device.

[Problem that the invention seeks to solve]

In the above-mentioned selective calling system with display, each of the plurality of display-equipped selective-call receiving devices is given a unique self-number, so it is impossible to call multiple display-equipped selective-call receivers in common. It was possible. Therefore, it is conceivable to give a common number to each display-equipped selective call receiving device.

However, common calls can only be made to devices that store a common number, and the uses of common calls are limited.

SUMMARY OF THE INVENTION Therefore, the present invention has been made with the object of providing a selective calling system with a display that allows users to arbitrarily select a receiving device for selective calling with a display that is commonly called.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a caller with a call signal that calls a plurality of display-equipped selective call receiving devices, a message signal that follows this call signal, and an identification signal included in this message signal. The selective call receiving device with display receives the selective call signal, and when the identification number set and stored in the selective call receiving device with display is included in the identification signal, selective calling is performed. A selective call method with display is adopted.

[Effect]

In the display-equipped selective call system according to the present invention, a plurality of display-equipped selective call receivers are called by a call signal. Then, further selection is made among the plurality of display-equipped selective call receiving devices.

The message signal includes an identification signal.

On the other hand, an identification number is set in the display-equipped selective call receiving device.

Then, selective calling is performed when the identification number is included in this identification signal.

Note that the identification number is not limited to a numerical number, but also a symbol.

A binary code or the like may be used as long as it can be determined that the identification signal includes an identification number.

Therefore, the identification signal corresponds to a plurality of identification numbers, and the display-equipped selective-call receiving device determines that this identification signal includes the identification number set and stored in the display-equipped selective-call receiving device.

By arbitrarily changing this identification signal, the caller can arbitrarily select the display-equipped selective call receiving device to be called.

〔Effect of the invention〕

According to the display-equipped selective call system of the present invention, a caller can make a common call to any display-equipped selective call receiver.

Therefore, it can be said that the display-equipped selective call system according to the present invention is a display-equipped selective call system that has a wide range of uses for users.

11 is a receiving section, 12 is a waveform shaping section, and 13 is a microcomputer. 14 is a storage device consisting of ROM, RAM, etc., and both reading and writing thereof are controlled by the microcomputer 13.

Reference numeral 15 denotes a sound generating section, which makes the speaker 16 sound.

Reference numeral 17 denotes a display driving section, which drives the display 18 to display according to instructions from the microcomputer 13. The display 18 is, for example, an LCD. Reference numeral 20 denotes a battery saving unit that controls power supply from a battery 21 built into the selective call receiving device 1 with display, and causes the selective call receiving device 1 with display to operate intermittently to suppress consumption of the battery 21. The control switch 19 consists of a numeric keypad and function keys.

FIGS. 2(a), 2(b), 2(c), and 2(d) are diagrams showing the signal structure of the selective calling signal C.

The synchronization signal SC is a signal for synchronizing the display-equipped selective call receiving device l with the transmission speed of the selective call signal C. Call signal PC is originally a selective call receiving device with individual display.
This is a signal for selecting the caller, and is a signal for the display-equipped selective call receiving device 1 to check against its own number to determine whether or not it has been called. The identification signal DC will be described later.

Message signal MC is a signal obtained by encoding an arbitrary message.

FIG. 2(a) shows the basic structure of the selective call signal C.

FIG. 2(b) shows an example in which the identification signal DC is positioned at the beginning of the message signal MC.

FIG. 2(C) shows an example in which the identification signal DC is positioned at the end of the message signal MC.

Figure 2 shows an example in which identification signals DCI and DC2 are placed at the beginning of each message signal MCI and MC2 in order to cause two message signals MCI and MC2 to be received by different display-equipped selective call receiving devices 1, respectively. ing.

Next, the identification number, identification signal DC, and identification conditions will be explained.

In this embodiment, the calling signal and self number are common to a plurality of display selective call receiving devices.

In this embodiment, a plurality of display-equipped selective call receiving devices selected by this call signal are called a group.

Within this group, the calling party and the called party constitute a unique selective calling system.

In this embodiment, the identification number is 0000 for each group.
~9999 is provided. Of this identification number, 0000
-0009 is used as a function number for specifying the importance of a message, such as a message with low information importance (0000) or a message with high information importance (0001). Identification numbers from 0010 to 9999 are used as selection numbers for individual designation within a group, information designation indicating the content of a message, and the like. These identification numbers are input from the numeric keypad of the control switch 19.

Further, a logical sum condition corresponding to an identification condition and a logical condition of a logical product condition are inputted from the function keys of the control switch 19.

For example, if the person with selection number 0020 wants only messages of high importance, select “0020.AND, 0010.
Set as °゛. Also, if you wish to call either the person with selection number 0020 or the person with selection number 0025, select "0020.OR."

0025”.

On the other hand, the identification signal DC is transmitted in the form of specifying an identification number.

For example, when calling all display-equipped selective call receiving devices belonging to a group, a signal indicating "ooio..." is used. Also, when calling a person with selection number 0020 belonging to a group, a signal indicating 0020'' is used.
When calling a person with selection number 020 and a person with selection number 0025, a signal indicating "°0020.0025" is used.

Also, for any selection number range in the group, “°
0040 to 0065''.

In this way, it is assumed that no special identification conditions are given to the identification signal DC. However, as another example,
The identification signal DC may also be given an identification condition corresponding to a logical sum or a logical product.

Furthermore, if the identification number specified by the identification signal DC includes the identification number set in the selective call receiving device with display under the logical condition between the identification numbers set in the selective call receiving device with display, it is determined that there is a call. judge.

For example, in a selective call receiving device with display, "°0020
, AND, 0001", the identification signal is "
Unless the signal contains both 0020° and "0001", the calling operation will not be performed.

Also, “”0020. If set to OR, 0025°, the identification signal will be “'0020.” or “0025.”
If the signal does not include one of the following, the calling signal will not be issued.

Note that if there is no particular function designation from 0000 to 0009, it is assumed that oooo is designated.

In other words, the importance of the message is considered to be low.

Next, the operation of this embodiment will be explained based on the drawings.

The calling party transmits a calling signal, an identification signal, and a number or symbol corresponding to a message signal to the base station from the nearest telephone.

A selective call signal C transmitted from a base station (not shown) is received by the receiving section 11 from the antenna 10 of the display-attached selective call receiving device 1 . The received selective call signal C is shaped by the waveform shaping section 12 into a rectangular wave that can be manually inputted into the microcomputer 13 . Then, it is stored in a predetermined area of the storage device 14.

The ROM, which is a read-only memory of the storage device 14, stores a self-number corresponding to the individual call signal PC.

On the other hand, the RAM, which is a readable and writable memory of the storage device 14, stores a plurality of identification numbers written by the user from the control switch 19 and logical conditions between the identification numbers.

The microcomputer 13 operates by repeatedly executing a predetermined program.

FIG. 3 is a flowchart showing one cycle of operation of the microcomputer 13.

In step 101, the selective call signal C from the waveform shaping section 12 is input as data. In step 102, the individual calling signal PC is extracted from the selective calling signal C. In step 103, it is determined whether the individual call signal PC matches the own number stored in the storage device 14.

In step 104, it is determined whether an identification number is set in the storage device 14 or not.

In step 105, the message signal M of the selective call signal C is
The identification signal DC is extracted from C. This extraction is performed by extracting data at the position where the identification signal DC should be located, if the position of the identification signal DC included in the message signal MC is determined in advance. Furthermore, if the position of the identification signal DC is not determined, predetermined signals may be inserted at the beginning and end of the identification signal DC.

In step 106, it is determined whether the selection number is included in the identification signal DC and satisfies the logical conditions. For example, if the identification number and logical condition are "OO20°AND, 0001.
OR, 0025", the identification signal DC needs to be a signal containing at least either "0020" or "0025". If it branches to "No" here, the calling operation will not be performed. .

If the branch branches to "YES" in step 106, the process proceeds to step 107. In step 107, it is determined whether "0001", which is the message importance designation, is set. Only messages with high importance are accepted. The function number "0001" is set when you want to call, so if this is not set, call operation (step 11), which will be described later, is set.
0 to 112) are executed. In step 108, it is determined whether the identification signal DC includes the function number "'0001". If "0001" is not included, the message signal MC is decoded and stored in step 109.

As a result, when the message is of low importance, only the message is stored.

Messages memorized here include user controls,
It is displayed by a predetermined operation of the roll switch 19.

If it is determined in steps 107 and 108 that the function number "0001" for specifying the importance level is not set, or that the function number "0001°" is set and is included in the identification signal, step 110 -112 paging operations are executed.

In step 110, message signal MC is decoded and stored.

In step 111, a command is given to the sound generation section 15 to cause the speaker 16 to produce sound.

This ringing alerts the called party to the call and stops the ringing. Then, by a predetermined operation of the control switch 19, a message is displayed on the display 18 in step 112. Here, when a plurality of identification numbers and logical conditions are set, the selected identification number and logical condition are displayed.

An example of the use of this embodiment described above will be explained.

First, if the called party does not set an identification number, it operates in the same way as a conventional selective call receiving device with display. That is, steps 101, 102, 103, 10 in FIG.
As shown in the processing of 4,110,111,112,
It will ring only when the calling signal PC and the own number match,
Display messages.

Furthermore, in this embodiment, the identification number set in the display-equipped selective call receiving device is divided into a function number and a selection number.

By setting the selection number to a number unique to the individual within the group, it is possible to selectively call the individual. Further, by setting the selection number according to the type of message, for example, stock information or traffic information, it is possible to selectively call according to desired information. Furthermore, the importance of a message is expressed by a function number, and the presence or absence of a sound is switched depending on the importance of the message. This allows the called party to restrict calls when he or she does not want to receive calls, such as during a meeting.

Additionally, the called party can add logical conditions between the selection number and the feature number, allowing various combinations to be set. For example, “0020,OR,0025
,OR,0030", the identification signal becomes "'
You can receive a call when it contains either OO20°'', "0025" or 0030".

Further, the identification signal can specify one identification number or a plurality of identification numbers. for example,"
OO20” or “0010゜~゛°,”’0025
．． ~． You can also specify a selection number range of the identification number, such as "0040".Then, in the selective call receiving device with display, the selection number set in the selective call receiving device with display is selected in this identification signal under logical conditions. The presence or absence of a call is determined based on the fact that it is included in the .

Further, in this embodiment, it is not necessary that the identification signal and the identification number match, and it is sufficient that the identification signal includes the identification number satisfying the logical condition. Note that this identification condition may be added to the identification signal.

In this way, in the selective call receiving device with display of this embodiment,
A user of the selective call receiving device with display can configure an original selective call system using the identification signal and the conditions between the identification numbers and the identification numbers. Therefore, it can be said that the selective call receiving device with display has a wide range of uses for users.

In this embodiment, the identification number is a four-digit number, but it may also be a symbol such as an alphabetic character, or a binary code.

Also, among the logical conditions, even if you do not set the OR ", which corresponds to the logical sum condition, if no logical condition is set,
“OR” and if the function number is set, “
It may be assumed that "AND" is set.

Further, in this embodiment, the function numbers are determined to be 0000 to 0009, and the operations according to each function number are also determined in advance.

For example, 0001 desires only messages of high importance, and when a message of low importance is called, only the message is stored, and when a message of high importance is called, a sound is made and the message is stored.

However, it is also possible to predetermine only the operations of the display-equipped selective calling device that are selected by function numbers, and allow the user to set the function numbers corresponding to each operation using the ten keys and function keys of the control switch 19. In this way, the user of the selective calling device with display can construct an original selective calling system based on the function number and the operation of the selective calling device with display corresponding to this function number.
