Abstract

PURPOSE:To easily confirm the fact that a message is transmitted normally to a callee, by detecting a caller address signal included in a message signal, and returning a signal required for a caller. CONSTITUTION:The caller transmits a numeral or a mark equivalent to the message signal including a response request signal and an address signal from the nearest telephone set, etc. The microcomputer 13 of a reception part extracts a call signal out of the message signals, and compares the call signal with its own number stored in a memory device 14, and when they coincide, displays a reception message on a display device 18. At this time, if the response request signal is outputted, the computer 13 extracts the caller address signal from the message signal, and sends a confirmation message, etc., to the caller based on the caller command of the callee.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to improved reliability of information transmission in a selective call receiving device capable of displaying messages.

[Prior art]

The selective call receiving device with display has a unique self-number assigned to its own device, and when a paging signal transmitted from the base station matches the self-number, it determines that it is a call to its own receiving device and sounds a buzzer. It is configured to make a sound to notify the holder. Furthermore, there is also known a device that not only notifies the user of a call, but also displays a message on a display according to the transmitted data. There has been a growing demand for the use of this data transmission function to transmit more and more sophisticated data.

[Problems to be solved by the invention]

In this way, the display-equipped selective call receiving device is specified by its own unique number corresponding to a telephone number, and can send a message to the specified display-equipped selective call receiving device. However, since the data is transmitted in one direction, there is a problem in that the calling party cannot confirm that the information has been properly transmitted to the called party. Additionally, a combined system of a car phone and a selective call receiving device with display has been proposed, but it is difficult to operate the car phone if the selective call receiving device with display is called while driving. , it may be difficult to answer immediately using a car phone. In such a case, if there is no response, the calling party has no choice but to determine that the called party is unknown. Therefore, from the display-equipped selective call receiver to the caller's display-equipped selective call receiver via the car phone, "
I can't respond because I'm driving. If messages such as "Please wait a moment" can be automatically transmitted, the effect of the combination of a car telephone and a selective call receiving device with a display will be even stronger. Furthermore, it is troublesome to call the caller for the sole purpose of confirming that the transmitted data has been transmitted to the called party, as the caller may not be able to speak immediately due to a busy line. There is. Furthermore, when transmitting data to a large number of people at the same time and getting confirmation of the data, there is a delay in not only the called party but also the calling party being busy answering the telephone. In such a case, if confirmation messages from the called party are transmitted one after another to the caller's selective call receiving device with display, the called party does not have to wait for a call and the caller can answer the phone. It is convenient and frees you from the hassle of Furthermore, considering that the display-equipped selective call receiving device is a simple mobile data receiving device, it is also possible to configure a simple two-way mobile data transmission system by using public telephone lines for transmission. The present invention was made to solve the above-mentioned problems, and its purpose is to easily confirm that the message has been successfully transmitted to the called party, and to provide two-way data. The purpose is to facilitate exchange.

[A must-have method to solve problems]

The configuration of the invention for solving the above problems is as shown in the concept in FIG. When the call signal is received by the machine M1 and the call determination means M2 determines that the call signal matches the own number, the display means M3
In the selective call receiving device with a display that displays a message in accordance with a message signal by driving a response request signal detecting means M4 for detecting a response request signal from the message signal.
and an address signal detecting means M5 for detecting an address signal specifying a response destination from the message signal, and when a response request signal is detected, a response destination according to the detected address signal in response to the calling command. This is because a call control means M6 is provided for outputting a signal for making a call.

[Effect]

When the calling party requests a response from the called party, the calling party includes a response request signal in the message signal. The response request signal detection means M4 receives this response request signal and detects it from the message signal, and the address signal detection means M5 detects an address signal specifying the response destination from the message signal. This address signal is a signal that specifies a response destination, such as a telephone number of a calling party or a third party, or a calling number of a selective call receiving device with a display. When a response request signal is detected, the call control means M6
In response to a call command, the device outputs signals necessary for making a call according to the detected address signal. This signal is typically output to a telephone line via a phono coupler, coupled to a home or mobile phone, or wirelessly. In addition, the calling command may be given manually by the called party, or
It is automatically granted when certain conditions are met. In addition to calling a response destination, the call control device can also send fixed or selected data. This operation simplifies the response operation for the called party holding the display-equipped selective call receiving device to receive data.

The C1 identification condition 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 numbers are set from 0000 to 0000 for each group.
Provide up to 9999. Among these identification numbers, 0000~
0009 is a response request number (
Used as a function number such as 0006, 0007, 0008>. 0006 indicates the first response request;
A response request means to respond by telephone to the response destination of the telephone number specified by the address signal AC. 0007 is the second
The second response request is the address signal AC.
0008 means to respond with a fixed confirmation message (for example, "Reception OKJ, etc.") to the selective call receiving device with display of the response destination specified by the self number and selection number specified in . 3 response request, and the third response request means to respond with arbitrary data.In addition, the identification numbers 0010 to 9999 are used to specify individuals within a group and information indicating the content of the message. This selection number is input from the numeric keypad of the control switch 19 and is set in the storage device 14.The selection number is used together with the self number to set the call conditions of the display-equipped selective call receiving device. The call condition is freely set by the user using the logical sum condition and the logical product condition input from the function keys of the control switch 19. For example, the call condition is set by the user with the selection number 0020 or the selection number 0025. If you wish to call “0020. OR,0025''.On the other hand, the identification signal DC is sent in a form that specifies the identification number.For example, when calling a person with selection number 0020 who belongs to a group, a signal indicating ``0020'''' is sent. and when issuing the first response request to the person with selection number 0020, “0020
．． 0006'". When a second response request is made to all display-equipped selective call receiving devices belonging to the group, the signal indicates "0010. ~,0007", and when instructing the third response request to the person with selection number 0020 and the person with selection number 0025, "OO2
It is a signal indicating 0,0025,0008″'.In addition, for an arbitrary selection number range, “0040. ~．
0065″'. When the selection number specified by the selection signal EC satisfies the logical condition between the selection numbers set in the selective call receiving device with display, it is determined that there is a call. Determine. For example, in a selective call receiving device with display, "OO20
. If it is set as OR, 0025'', the selection signal EC
If the signal contains either "0020," or "0025", the calling operation will not be performed. Next, the operation of this embodiment will be explained based on the drawings. The calling party transmits numbers or symbols corresponding to a message signal including a paging signal and, if necessary, a selection signal, a response request signal, and an address signal, to the base station from a nearby telephone or a transmitting-only device. A selective call signal C transmitted from a base station (not shown) is received by the receiving section 11 from a mobile device (not shown) via a signal terminal A. The received selective call signal C is shaped by the waveform shaping section 12 into a rectangular wave that can be input to the microcomputer 13, inputted to the microcomputer 13, and 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. On the other hand, the RAM, which is a readable and writable memory of the storage device 14, stores a plurality of selection numbers written by the user from the control switch 19 and logical conditions between the selection numbers. The microcomputer 13 repeatedly executes the one-cycle processing procedure shown in FIG. In step 101, the selective call signal C from the waveform shaping section 12 is input as data. In step 102, the calling signal PC is extracted from the selective calling signal C. In step 103, it is determined whether the calling signal PC matches the own number stored in the storage device 14. If it is determined that the number matches the own number, it means that the own selective call receiving device meets the necessary conditions for calling.
The process moves to step 104. On the other hand, if the calling signal and the own number do not match, the process is terminated because the call is not to the own receiving device. In step 104, 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. Next, in step 105, it is determined whether a selection number is set in the storage device 14. If the selection number has been set, in step 106, the selection signal EC
Then, it is determined whether the selected number satisfies the logical condition and is included. For example, if the selection number and logical condition are "0020.
OR,0025", the selection signal EC
must be a signal containing at least either "0020'" or "0025"'. Here, if it is determined as "N○'", the process is terminated without performing a calling operation because the calling condition for the own receiving device is not met. Furthermore, if it is determined in step 105 that no selection number has been set, it is assumed that all calls will be accepted and the calling conditions regarding the selection number have been met, so the determination of "YES" in step 106 is Similarly, the process moves to step 107. In step 107, the received message is displayed on the display. In step 108, a response request signal R is sent to the message signal.
It is determined whether or not C exists. If there is no response request signal RC, it means that all reception processing has been completed, and the microcomputer 1B ends the processing. If it is determined in step 103 that there is a response request signal, the process moves to step 109 and the address signal AC is extracted from the message signal. Next, in step 110, the response request signal RC is read to determine the manner of the response. If the response request signal RC is 0007, it is a second response request, and the process moves to step 111, where the response request is displayed. Then, in step 112, the system waits until a calling command is given from the control switch 19 manually by the called party. The called party recognizes the received message displayed in step 107, operates the control switch 19, and issues a calling command. When the calling command is given, the process moves to step 113. In step 113, a calling procedure is executed to call the response destination selective call receiving device with display from the address signal AC. It outputs to the mobile station a control signal, the own number of the selective call receiving device and, if necessary, a selection number, and a message number specifying the confirmation message stored in the selective call receiving device with display to which it responds. The mobile device inputs these signals and automatically calls the selective call receiving device with display of the response destination and transmits a confirmation message, and after the processing is completed, the processing of the microcomputer 13 ends. If the response request signal RC is determined to be 0008 in step 110, it is the third response request, so the process moves to step 114, where the response request is displayed, and in step 115, the called party's manual operation is performed. Control switch 1
After waiting until a calling command based on data designation is given from step 9, in step 116, a procedure for calling the response destination display-equipped selective call receiving device similar to step 113 is executed. However, in the case of the third response request, the message to be transmitted is not fixed to V(i M7J message,
Free data stored in the storage device 14 or input from the control switch 19 is transmitted. If the response request signal RC is determined to be 0006 in step 110, this is the first response request, so the process proceeds to step 117, where a telephone call request is displayed, and in step 113, the called party's hand is When a call command, which is a calling command, is given from the control switch 19 by operation, the process moves to step 119, where the telephone number of the response destination specified by the address signal AC is output to the mobile device along with the control signal.
The mobile device performs a calling operation according to the telephone number. When this automatic calling operation is completed, it becomes possible to talk to the person at the answering destination using the car telephone. In addition, when a calling command is given in step 118 by a waiting message output command instead of a call command, the process moves to step 120, and similarly to step 111, a fixed call is sent to the selective call receiving device with display of the response destination. A waiting message (for example, "Driving, please wait for a while") is sent. In this manner, when the calling party transmits the first response request signal, the called party can notify the calling party that it is not possible to answer the telephone immediately due to the state at the time of reception. If the caller expects a response from this waiting message, the address signal must include the answering party's telephone number, the own number of the selective call receiving device with display of the answering party, and the selection number if necessary. There is. Note that the response destination and the calling party do not necessarily have to match. Further, the first response request signal can also be given by a message such as "Call ○○○○". In the above embodiment, an effective means of data transmission is realized by combining a car telephone and a selective call receiving device with a display. Similar means can also be realized by connecting to a line. Bidirectional data transmission using the display-equipped selective call receiving device is then easily performed.

【Effect of the invention】

The present invention detects a response request signal and an address signal included in a message signal, and when a response request signal is present and a calling command is given, a signal is sent to call the response destination specified by the address signal. Since the message is outputted, it is easy to confirm that the message has been correctly transmitted to the called party. Furthermore, bidirectional data exchange using the display-equipped selective call receiving device can be easily performed.
