Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paging receiver with an auto dialer function for converting a telephone number or a message into a dial tone and outputting the dial tone.

[0002]

2. Description of the Related Art Some paging receivers with a numerical or character display function have an automatic dialer function capable of converting a telephone number and an input message into a corresponding dial tone for output. A paging receiver capable of transmitting and receiving the above message can transmit a message requiring a response from the other party, receive a response message to the message, and confirm the message content.

However, since the conventional paging receiver described above merely stores and displays the received message, when a message requiring a response is transmitted,
The user memorizes the contents of the sent message and the telephone number and name of the destination, and the contact telephone number in the message information received when the message is subsequently received, or a call that identifies multiple callers. It has been necessary to know who the sender is from the call type information in the code (for example, function bit information in the address code word of the POCSAG system) and to determine which received message is the response message to the above-mentioned transmitted message. Therefore, if you send multiple messages that require a response, you must memorize at least the destination data (phone number or name) of all the sent messages and search for the received message. Checking the message was troublesome.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a paging receiver with an auto dialer function, which can easily know whether a received message is a response message to a message already transmitted.

[0005]

According to the present invention, destination data (telephone number or name) of a message that has already been transmitted is stored in a memory, and the above-mentioned destination data is included in a calling code or a received message. Judge whether or not,
It is for notifying whether or not those messages are response messages to the transmitted message.

The decoder unit 13 is a circuit for comparing whether or not the input digital data matches its own calling number (address code) stored in the ID-ROM 14, and when the calling numbers match, a match detection signal and subsequently The received data is output to the CPU 15, and when the calling numbers do not match, the reception unit 12 is instructed to terminate the reception.

The CPU 15 is a central processing unit for detecting a key input from the data input key group 2 and the control key group 8 and storing the received message in the received message memory 16, and receives the received message from the decoder unit 13. When the process is completed, the received message is stored in the received message memory 16, the reception termination instruction is given to the decoder unit 13, and the speaker 18 is driven through the driver 17 to notify that there is a call.

The transmission data memory 19 is a memory for storing transmission destination data such as a transmission destination telephone number or name together with a transmitted message. As shown in an example of the configuration in FIG. 3, a transmission data memory 19 and a TelNo. A memory area, a memory area for storing information indicating whether or not a message is added at the time of transmission, a message memory area for storing message contents, and a transmission time memory area for storing transmission time information. .

The received message memory 16 is a memory for storing the received messages together with information indicating whether or not those messages are responses to the transmitted messages. As shown in FIG. 4, the reception message memory 16 has a call type information memory area for storing call type information (for example, function bit information in an address codeword of the POCSAG system) for identifying a plurality of callers. , A response message bit for storing response information indicating whether or not each received message is a response to the transmitted message, a message memory area for storing the content of the received message, and a reception time memory area for storing the reception time information It consists of and.

The TelNo. The memory 20 is a memory that stores the registered name and telephone number. In this memory, for example, a name and a telephone number are stored in association with each other as shown in FIG. 5, and the telephone number is a company telephone number, a home telephone number, a numerical display type (NP) or a character display type. (IP) Tel type data indicating whether the telephone number is the telephone number of the paging receiver is stored.

A character generator (CG) 21 is a ROM for storing the character fonts corresponding to the characters and numerical codes stored in the above memories. The DTMF signal generation unit 22 uses TelNo. This is a circuit for converting a telephone number read from the memory 20 or a created transmission message into a corresponding dial tone signal (DTMF signal: double tone multi-frequency signal) and outputting it from the speaker 18 as a dial tone.

Next, the main processing operation of the above embodiment will be described with reference to FIG.
This will be described based on the flowchart of FIG. 6 is a message transmission process, FIG. 7 is a message input process, FIG. 8 is a resend process, and FIG. 9 is a flowchart showing the contents of an incoming call process.

In the transmission process of FIG. 6, first, step S ₁
In, select the telephone number of the telephone you want to call. To select this phone number, switch to Tel mode and
The memory that can be searched by operating the wn key 5 is set to TelNo.
After setting in the memory 20, the Up key 4 or the Down key 5 is operated. When the Up key 4 and the Down key 5 are operated to select a specific name, the name, telephone number and Tel type selected in step S ₁ are displayed on the display unit 1. Then, in the next step S ₂ , it is judged from the Tel type of the telephone number displayed whether the called party is a paging receiver with a message receiving function. When was the message receiving function with the paging receiver proceeds to next step S _3, the letter "Messages" earlier with first sets the transmission inhibit flag F1 flushing displayed. When the Mes key 6 is operated, the message input process of step S ₄ is executed. In this message input processing, message data input from the data input key group 2, that is, message data such as abbreviated code and telephone number of a fixed phrase message is stored in a display buffer (not shown), and the created message is displayed on the display unit 1. Is displayed. Further, when there is an input from the data input key group 2, the message flag F2 is set, and when the input of the message is finished and the # key is operated thereafter, the transmission prohibition flag F1 is reset.

Following the message input process, step S ₅
Then, it is determined whether or not the transmission switch 7 has been operated. When the transmission switch 7 is operated, when the transmission inhibit flag F1 at the next step S _6, it is determined whether it is set, the flag F1 is set, step S
Return to ₄ and accept the message input again.

On the other hand, step S₆The transmission prohibited flag

When the callee telephone number output from the speaker 18 is input from the mouthpiece of the touch-tone telephone, the wireless base station instructs the transmission message to be input. Therefore, the user operates the transmission switch 7 again. Send the displayed message. When the operation of the transmission switch 7 is detected in step S ₁₁ , the message data described above, that is, numerical data such as abbreviated code and telephone number data, and symbol data are converted into dial sounds and output from the speaker 18 in step S ₁₂ . To be done. And the next step S
The message data already transmitted in ₁₃ is the transmission data memory 19

[0021] If an operation of the numeric keys in the determination of step S _24, the procedure proceeds to step S ₂₈ * to determine whether the operation or not of the key. If the key was operated, the next step S
_{At 29} , it is determined whether or not the last input was the * key.
When the * key is input twice in succession, this means cancellation of the message, and the input data, the counter and the message flag F2 are cleared. Step S ₂₈
If the * key is not operated in the determination of No., it is determined that a key other than the numeric key and the * key, that is, the # key is operated, and the message input processing is ended.

After the message transmission is completed as described above, the processing operation in the case of transmitting the same message to the same calling party again will be described with reference to the flowchart of the retransmission processing of FIG.

First, the Up key 4 is operated to set a searchable memory in the transmission data memory 22, and then the Down data 5 (Up key 4 if necessary) is operated in response to the operation of the Down key 5 in step S _31. The telephone numbers stored in are sequentially displayed on the display unit 1. Then, in step S ₃₂ , it is determined whether or not a message is added to the selected telephone number from the data indicating the presence or absence of the message in the transmission data memory 19. Sets the message flag F2 in step S ₃₃ when was attached message. And to determine the operation of the transmission switch 7 at the next step S _34, when the transmission switch 7 is operated by converting the numerical data excluding the sign data of the telephone number data proceeds to step S ₃₅ in the dial tone speaker Output from 18.

When the transmission of the telephone number is completed, step S
_{At 36} , it is determined whether or not the message flag F2 is set, and if the flag F2 is not set, the processing is ended as it is.

On the other hand, when the message flag F2 is set, the process proceeds to step _S37 and the transmission message stored corresponding to the telephone number in the transmission data memory 19 is read out and displayed on the display unit 1. Then, in the next step S ₃₈ , it is determined again whether or not the transmission switch 7 has been operated. When the transmission switch 7 is operated, the process proceeds to step S ₃₉ , and all the numerical values and symbol data of the message displayed on the display unit 1 are converted into dial sounds and output to the speaker 18.

Next, the processing contents of the incoming call processing when a call is received and a message is received will be described with reference to FIG. When it is a call with a message added, the message received in step S ₄₁ of FIG. 9 is temporarily stored in a message buffer (not shown) inside the CPU 15. Then, in the next step S ₄₂ , it is determined whether or not the message received is the same as the message received immediately before, that is, whether the same message is repeat call data repeatedly sent, and if it is repeat call data, that data has already been received. since it is stored in the message memory 16 and terminates the process to clear the data in the message buffer proceeds to step S _43.

On the other hand, the process proceeds to step S ₄₄ if not repeat call data, the already stored message in the received message memory 16, after the start address empty to shift down by one address minute, receive data message buffer Transfer to the top address of the message memory 16. At this time it is compared with the destination telephone number in the numerical data and the transmission data memory 19 in the received message in step S _45, to determine if a reply message to a message received message has already transmitted. And when the numerical data matches the specific destination telephone number, and a response message bits in the next step S ₄₆ to "1", and stores information that the received message is a message of a response to message sent step the procedure proceeds to S _47.

Further, when there is no matching telephone number proceeds to call informing process in the step S ₄₇ a response message bits as remains in the initial state of "0". Incidentally, step S
_{In the} process of determining whether the received message of ₄₅ is the response message, the name corresponding to the telephone number is set as the TelNo. Alternatively, the data may be obtained from the memory 20 and stored as the destination name, while the name of the sender may be obtained from the received call type information to determine whether the names match. Further, instead make a response message bit in step S _46, so as to store the address in the transmission data memory 19 of the transmission message phone number or name as described above matches the memory area of the corresponding received message Is also good. In this case, since the corresponding send message can be immediately displayed from the stored address, it is possible to easily confirm the send message together with the received message.

In the call notification process of step S ₄₇ , the speaker 18 of FIG. 1 is driven according to the call type information to emit a ringing tone. At the same time, the information stored in the received message memory 16, that is, the call type information, the received message, the information indicating whether the message is a response message, the arrival time, and the like are displayed on the display unit 1.

As described above, in the above embodiment, the information indicating the sender in the received message, for example, the telephone number or call type information, is compared with the destination data (destination telephone number, name, etc.) of the already transmitted message. Then, it is determined whether or not the received message is a response message to the above-mentioned transmitted message, and the determination result is stored for each received message as response information indicating whether or not those messages are response messages. The message can be displayed separately from the message.

Therefore, when a message requiring a response from the other party is transmitted and various messages including the response message are received, the response message can be easily searched from the messages. Further, since it is possible to know which transmitted message the response message corresponds to, even if the transmitted message is forgotten, the contents can be confirmed by looking at both messages.

[0032]

According to the present invention, it is possible to know whether or not a received message is a response message to a message that has already been transmitted, and to which transmitted message a response message corresponds. So
The received message can be confirmed more efficiently.
