Description

Pager and how it works

The present invention relates to a pager and a pager operation method, and more particularly, to a pager and a pager operation method capable of transmitting a reply message back to the sender.

There are various pagers on the market that receive radio calls or wireless paging through wireless paging services, and the number of wireless paging service subscribers has increased significantly. In recent years, many pagers are equipped with functions for receiving and displaying messages sent from the caller, i.e., the sender. The radio paging signal or radio paging signal containing the message from the transmitting side is transmitted by the radio paging service, and the pager receives the radio paging signal and displays a message included in the signal. The type of characters that can be displayed by the pager varies depending on the pager, and the number of pagers having a function of displaying characters other than numbers, such as alphabets and symbols, is increasing.

However, a conventional pager is a terminal having only a message receiving function and no reply function. That is, in order to inform the message sender that the message was correctly received in the conventional pager, the message receiver makes a call to the message sender through a payphone or a mobile phone, or a caller of the sender pager via a payphone or a mobile phone. It must contact the message sender by dialing the number and sending a reply message via the wireless paging service.

On the other hand, as disclosed in Japanese Patent Application Laid-Open No. 7-7287, a terminal having a function of receiving a message through a wireless paging service and displaying a message is presented in a cellular phone dedicated to sending a message. With this type of terminal, a terminal user who has received a message from the sender can dial the correct phone number of the sender and notify the sender of the message by looking at the telephone number in the message displayed on the LCD of the terminal or the like.

However, in order to inform the sender of the receipt of a message with this kind of terminal, the terminal user must operate the terminal to dial the sender's telephone number and tell the sender that the message has been received correctly. Therefore, in a situation where it is impossible to dial and talk, such as during a meeting, it is impossible to notify the sender of the reception of a message.

Moreover, with this type of terminal, it may take a long time for the user to press the wrong button or enter a reply message during the user's dialing operation. Therefore, this type of terminal can incur a lot of unnecessary phone bills.

Now, with reference to the drawings will be described in detail preferred embodiments according to the present invention.

1 is a block diagram illustrating functional blocks constituting a pager according to a first embodiment of the present invention, and FIG. 2 is a flowchart illustrating steps related to the operation of the pager of FIG. 1.

The pager shown in FIG. 1 includes a receiving unit 101, a control unit 102, an operation unit 103, a display unit 104, a notification unit 105, a telephone number memory 106, a telephone number retrieval unit 107, and a reply operation. The control unit 108, the wireless transmission unit 109, and the wireless transmission control unit 110.

The receiving unit 101 converts the received wireless paging signal, that is, the wireless paging signal into a digital signal, and then transmits the digital signal to the control unit 102. The control unit 102 confirms the selection call number ID and extracts the received message from the digital signal.

The operation unit 103 is a block for receiving a user operation on the pager, and is composed of a key switch such as, for example, a scroll key and an enter key. The display unit 104 is composed of, for example, an LCD (liquid crystal display element), and displays a reception message, a pager function, and a pager operation state. The notification unit 105 is composed of, for example, an LED (light emitting diode), a speaker, a vibration motor, and the like, and is operated to inform the user that a call has been received.

The telephone number memory 106 may store at least the telephone numbers of other pagers entered by the pager user, and may also store information such as a name and address corresponding to each telephone number. The telephone number search unit 107 searches for and extracts a telephone number from the received message. Alternatively, the telephone number search unit 107 searches for and extracts a string of numbers corresponding to a part of the telephone number from the received message, and searches whether the extracted string of numbers matches the telephone number stored in the telephone number memory 106. If there is a phone number that matches the search result, the searched phone number is transmitted to the reply operation control unit 108.

The reply operation control unit 108 operates and controls the radio transmission control unit 110 to return to the pager of the message transmission side. The wireless transmission control unit 110 operates the wireless transmission unit 109 and establishes communication with the wireless paging service using the telephone number retrieved by the telephone number retrieval unit 107. The reply operation control unit 108 then transmits a predetermined prestored reply message to the sender pager via the wireless paging service. After the reply operation is completed, the power is cut off from the wireless transmitter 109 by the wireless transmitter controller 110.

Incidentally, the control unit 102, the telephone number retrieval unit 107, the half-operation control unit 108, and the wireless transmission control unit 110 are, for example, a CPU (central processing unit) and a ROM (read only) as shown in FIG. Memory), a random access memory (RAM), and the like, and are implemented as a microcomputer device. A CPU such as Z80 may be used as the CPU in FIG. 3, and a flash ROM and an SRAM (static RAM) may be used as the ROM and the RAM in FIG. 3, respectively. As a power source of the wireless transmission unit 109 for performing wireless transmission, a battery such as a Ni-Cd battery that can maintain a constant voltage even though a large current is output can be used.

4A-4D are schematic diagrams illustrating an example of a signal format for calling a pager according to Post Office Code Standardization Advisory (POCSAG), which is widely used by many wireless paging services. 4A shows a radio call signal according to POCSAG. The signal shown in FIG. 4A includes eight frames, that is, F1 to F8. 4B shows a portion of a frame F1 of the signal of FIG. 4A corresponding to a call to the pager. Some of the frames shown in FIG. 4B include ID bits, data bits, check bits, and parity bits. The pager's Selected Call Number (ID), i.e. the message sent by the sender, is contained in the data bits. 4C and 4D show the contents of the data bits shown in FIG. 4B. In general, the data bits contain a message signal as shown in FIG. 4C and, in some cases, include an encryption information signal and a message signal as shown in FIG. 4D. The receiver 101 and the controller 102 in the pager of this embodiment may be designed to receive and control the radio call signal shown in Figs. 4A to 4D.

On the other hand, in the half body operation, a radio signal according to the signal format used in the portable cellular phone is transmitted by the radio transmitter 109 in order to establish communication with the radio paging service. That is, the dialing tone signal for calling the pager of the message transmitting side is transmitted by the radio transmitter 109 according to the signal format used in the portable cellular phone.

Next, the pager operation of this embodiment will be described with reference to FIG. In step 11 the pager waits for a call to the pager itself. In step 11, when a call to the pager is received, i.e., if the selection call number (ID) in the received radio call signal is confirmed by the control unit 102 to be the selection call number of the pager itself, the ringing tone is notified in the notification unit 105. The pager user is notified of the call reception through the vibration, etc., and the message in the received wireless call signal is extracted by the control unit 102 and displayed on the display unit 104 such as the LCD in the same manner as the normal pager (step 12). .

In step 13, the telephone number search unit 107 searches for and extracts a telephone number or a string of numbers corresponding to a part of the telephone number in the received message. If all of the telephone numbers have been extracted in step 13, the process proceeds to step 15. If a sequence of numbers corresponding to a part of the telephone number is extracted in step 13, the process proceeds to step 14. If no sequence of numbers corresponding to part of the telephone number is found in step 13, the process returns to step 11 and the pager waits for the next message reception.

In step 14, the telephone number retrieval unit 107 checks whether there is a telephone number embedded in the telephone number memory, including the numeric string extracted in step 13. If a telephone number including a string of numbers is found, the telephone number retrieval unit 107 determines that the found telephone number is the telephone number of the sender pager, and the process proceeds to step 15. For example, in step 13, when the string of numbers' 7890 'is found and in step 14 the telephone number '03 -3456-7890 (one example in Japan)' stored in the telephone number memory 106 is found, the telephone number search unit 107 determines that the telephone number of the sender pager is '03 -3456-7890 '. If no telephone number containing this string of numbers is found in step 14, the process returns to step 11, and the pager waits to receive the next message.

More specifically, in step 13, the extraction of the entire telephone number or the extraction of the numeric string corresponding to the portion of the telephone number may be performed in the following manner.

When the pager is configured to receive and display characters other than numbers, that is, alphabets, symbols, and the like, the telephone number retrieval unit 107 extracts a numeric string consisting of a predetermined number of digits from the received message, and the numeric string is transmitted. It is determined to be the telephone number of the side pager. For example, in Japan, a completed telephone number starts with '0', such as '03 -3456-7890 ', and the number of digits of the completed telephone number is 9 or 10. Therefore, the telephone number retrieval unit 107 can execute the extraction of the entire telephone number by searching for a string of 9 or 10 digits included in the received message. In particular, in Japan and the like, the charge number retrieval unit 107 can perform extraction by finding a string of 9 or 10 digits starting from the number '0'. On the other hand, a part of the telephone number of the message sender is included in a four-digit message in many cases, such as 'TOMORROW TENNIS 7890'. Therefore, the telephone number search unit 107 can extract a part of the telephone number by finding a string of four digits.

To improve the accuracy of the extraction, the entire telephone number or a string of numbers corresponding to the telephone number can be placed at a predetermined position in the message, such as at the end of the message. In this case, the telephone number retrieval unit 107 is placed at the end of the received message. Extraction can be performed by finding a string of numbers consisting of a predetermined number of digits.

To further improve the accuracy of the extraction, you can use phone number flags such as 'TL' in the message. For example, a message such as' TOMORROW TENNIS TL0334567890 'or' TOMORROW TENNIS TL0334567890TL 'can be used to show that the entire telephone number of the calling pager is '03 -3456-7890', or 'TOMORROW TENNIS TL7890' or 'TOMORROW TENNIS TL7890TL' Using a message such as this can be shown that part of the telephone number is '7890', the telephone number search unit 107 can perform the extraction by finding the telephone number flag 'TL' in the received message.

In the case where the pager is configured to receive and display only numbers, it is effective to use a telephone number flag such as '0000' as described above in order to perform an accurate extraction of the entire telephone number or an exact extraction of the string of numbers corresponding to the telephone number. . For example, a message such as' 5642345600000334334890 'or' 56423456000003345678900000 'sent by the numeric pager can be used to show that the entire telephone number of the calling pager is '03 -3456-7890', or '5642345600007890' or '56423456000078900000' By using a message such as this, it can be shown that a part of the telephone number is '7890', and the telephone number search unit 107 can extract by searching for the telephone number flag '0000' in the received message.

Subsequently, the telephone number determined by the telephone number retrieval unit 107 in step 13 or 14 is supplied to the half body operation control unit 108, and the half body operation control unit 108 starts the half body operation. The wireless control unit 110 turns on the power of the wireless transmission unit 109 (step 15), and after the wireless transmission unit 109 is activated to communicate with the wireless paging service, the wireless transmission control unit 110 Dialing to the telephone number determined by the telephone number retrieving unit 107 is executed. In accordance with this dialing operation, the above-mentioned dialing tone signal for calling the pager on the message sending side is transmitted by the radio transmitter 109 according to the signal format used in the portable cellular phone (step 16).

If communication with the wireless paging service is established, processing proceeds to step 17. Then, the predetermined reply message is transmitted from the reply operation control section to the radio transmission control section 110, and the operation of retransmitting the predetermined reply message to the transmitting side is executed in accordance with a procedure suitable for the wireless paging service. This predetermined message may be, for example, a message such as 'RECEIVED OK' (step 17). When the reply operation is completed, the process proceeds to step 18 and the wireless transmission control unit 110 cuts off the power from the wireless transmission unit 109.

As described above, according to the first embodiment, if a message is received from a sender and a message string or a numeric string corresponding to a part of the telephone number is included in the message, the predetermined reply message does not require the user to operate the pager. Can be automatically retransmitted to the sender.

In the second embodiment, the "sending side reply flag" is a character (ie, a character, a symbol, etc.) or a string of characters included in a message input at the sending side to request the recipient to return the message.

Referring to FIG. 6, the pager operation of FIG. 5 is almost the same as the operation of the first embodiment shown in FIG. 2 except that step 22 is executed between steps 12 and 13. After the message is received from the transmitting side and displayed on the display unit 104 (steps 11 and 12), the transmitting side reply flag checking unit 211 checks whether the receiving side reply flag is included in the received message. If the transmitting side reply flag is included, the telephone number is retrieved by the telephone number retrieval unit 107, the reply operation control unit 108, the wireless transmission unit 109, and the wireless transmission control unit 110 in the same manner as in the first embodiment. Judgment and half body operations are performed. If the sending side reply flag is not included, the process returns to step 11, and the pager waits for receiving the next message. For example, the sender half body flag may be determined to be a character 'RE' or the like at the end of the message. In such a case, if the received message is '0334567890RE', the judgment and reply operation of the telephone number is executed, and if the received message is '0334567890', the judgment and reply operation of the telephone number is not executed.
