Description

Detailed Description of the Invention Technical Field of the Invention The present invention transmits broadcast information received by an unspecified number of subscribers and information received by a specific subscriber over the same wireless line, and receives the information at a terminal. This relates to a wireless data reception method for display.

BACKGROUND OF THE TECHNOLOGY Conventionally, a service such as a pager with a display that allows a specific subscriber to receive necessary information and a service that allows an unspecified number of subscribers to receive information have been considered separately. Therefore, the wireless line that sends out to specific subscribers and the wireless line that sends out to an unspecified number of subscribers are separate lines, and a subscriber who wants to receive both services can use two terminals that can receive signals on each line. It is necessary to prepare. A wireless data reception method has also been proposed in which one terminal capable of receiving both lines is used and information from both lines can be received by switching the receiving line.

Prior Art and Problems The conventional method of preparing two terminals capable of receiving signals on each line for specific subscribers and unspecified large number of subscribers does not make effective use of the wireless line and is uneconomical. There were some drawbacks, such as: In addition, the system in which one terminal capable of receiving information from both lines is switched and used for each receiving line has the disadvantage that it is not possible to receive both services at the same time.

Purpose of the Invention In order to solve these drawbacks, the present invention transmits broadcasting information that can be received by an unspecified number of subscribers and information that can be received by a specific subscriber over the same wireless line. will be explained in detail.

Embodiment of the Invention FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, in which 1 is a PB telephone, 2 is a subscriber line exchange, 3 is a control station, 4 is a communication network device, and 5 is a block diagram showing the configuration of an embodiment of the present invention. P.B.
A signal receiver, 6 a tone signal transmitter, 7 a central control unit, 8 a memory, 9 a center, 10 a radio transmitting station, and 11 and 12 terminals.

FIG. 2 is a diagram showing an example of an information transmission format from the control station 3. As shown in FIG. In Figure 2, C is a code,
TN indicates a terminal number, and D indicates data.

The following information is intended for an unspecified number of subscribers,
When information targeted at a specific subscriber is sent, a method for selectively receiving the former information and a method for receiving the latter information only by a specific terminal will be described.

The subscriber sends the code of necessary information (for example, "001", the content is the stock price of company A) from among the information broadcasted by the control station 3 to an unspecified number of subscribers. Set it on the terminal 10. (Terminal 1
To set the code to 0, control station 3
A method in which the subscriber inquires for a code and sets it (for example, Japanese Patent Application No. 58-48288, Japanese Patent Application No. 58-45886),
A method in which the control station 3 automatically sets the terminal 10 according to instructions from the subscriber (for example, Japanese Patent Application No. 58-45887)
Various methods have been proposed. ) Also, a subscriber who wants to send information to the terminal 11 can use the PB telephone 1 to call the connection number to the control station 3 (for example, the special number "1
When dialing "Y"), connection is made to the control station 3 via the subscriber line exchange 2 using existing technology.The central control unit 7 of the control station 3 controls the communication path network device 4 to A signal receiver 5 and a tone signal transmitter 6 are connected, and a tone signal is sent from the tone signal transmitter 6 to the PB telephone 1. When the subscriber hears the tone signal through the PB telephone 1, the subscriber wants to display it on the terminal 11. When the information number (for example, "100", please return to the office as soon as possible) and the number of the terminal 12 to be displayed (for example, "0123456789") are sent as a PB signal, the PB signal receiver 5 of the control station 3 receives the information. Received. The central control device 7 of the control station 3 stores in the memory 8 the information "Hurry up to work" corresponding to the received information number "100" and the number "0123456789" of the terminal device 12. The control station 3 periodically accesses the center 10, collects various information, and transmits this information and information targeted at specific subscribers via the wireless transmitting station 10 in the format shown in FIG. are doing. The terminal 10 turns off its power during the time period when the information code and terminal number are being transmitted.
If the code "001" of the information received and displayed by the terminal 11 is found during that time, the power will continue to be turned on during the time when the information is being sent. If not, the power will be turned on using the next information code and terminal number. will be OFF until the time when is sent. Terminal 1
1 finds the information code "001" when the power is on, receives only the necessary stock price information of Company A, and displays it. On the other hand, the terminal 12 and the terminal 11
Similarly, during the time period when the information code and terminal number are being sent, turn on the power, find the number ``0123456789'' of terminal 12, and receive and display the message ``Hurry to the office.'' Note that it is also possible to receive information targeted at an unspecified number of subscribers and information targeted at a specific subscriber using the same terminal.

FIGS. 3 and 4 show flowcharts of processing operations of the control station and terminal of the present invention.

Effects of the Invention As explained above, since the information center transmits broadcast-like information targeted at an unspecified number of subscribers and information targeted at specific subscribers in a time-sharing manner over the same radio line, For subscribers who want to receive both services, they only need one terminal, they only need one wireless line, so they can make effective use of the wireless line, and they can receive both types of information at the same time. There is. In addition, we separate the time period for transmitting information codes and terminal numbers from the time period for transmitting information, and during the former time period, the power of the terminal is always turned on, but during the latter time period, the power is turned on only when necessary.
Since it is designed to do this, it has the advantage of saving battery power for the terminal.

Claims (1)

[Claims] 1 A control station transmits various information codes and information corresponding to the information code, or a terminal number and information corresponding to the terminal number, to one or more terminals using the same line, and the terminals transmit the information corresponding to the terminal number. In a wireless data reception method that receives and displays only the information corresponding to the information code set on the terminal, or only the information corresponding to the terminal number only on the terminal number, the single or plural terminal numbers and information to be received first. A single or multiple information code indicating the content is sent together, and then information corresponding to the transmitted terminal number and information code is transmitted together, and the terminal transmits the time period during which the terminal number and information code are being transmitted. is constantly monitored, and if the terminal number or the information code set in the terminal is detected during the time period, the monitoring is continued, and the information corresponding to the terminal number or the information code is selectively received. If both the terminal number and the information code set in the terminal are detected, monitoring is continued and both information corresponding to the terminal number and information corresponding to the information code are selectively received.
