Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a radio paging device, and particularly to a radio paging device suitable for allowing a called party to easily respond to a call.

(Prior Art) It has been said that the ideal form of mobile communication is telephone communication using a portable mobile device capable of two-way communication. However, in this type of telephone communication, in order to perform two-way communication, it is necessary to incorporate a transmitter that can obtain an output of several watts into the portable mobile device, and it is necessary to install a very large-capacity battery, which requires a large However, it was currently impossible due to weight considerations. Therefore, a paging receiver has been commonly used as an alternative to this. In this case, since the portable mobile device only needs to receive data, low power consumption is possible, and the power source can be an extremely small and low capacity battery.

(Problem to be solved by the invention) However, two-way communication no longer takes place,
The conventional requirements mentioned above will no longer be met. That is, the user of the paging receiver, after hearing the selective ringing tone if it is emitted, either contacts a predetermined location by telephone communication and asks for instructions, or if a voice instruction is emitted at the time of selective paging. In accordance with the instructions, the designated contacts were made. As a result, such paging systems have been utilized only for limited purposes and lacked versatility.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a radio paging device that is versatile, easy to operate, and can be applied to a paging system capable of bidirectional communication.

(Means for Solving the Problems) The first invention includes a generating means for generating self-identification information, a receiving means for receiving a transmitted signal, and a device capable of outputting the self-identification information to another device. output means, notification means for notifying the outside, detecting called device identification information from the signal received by the receiving means, and detecting called device identification information from the detected called device identification information and the signal generated by the generating means. The wireless paging device is equipped with a control means for controlling the notifying means to make a notification when the two are in a predetermined correspondence relationship by comparing the identification information of the wireless paging device with its own identification information.

The second invention includes a generating means for generating self-identification information, a receiving means for receiving a transmitted signal, a storage means for holding a predetermined signal received by the receiving means, and a storing means for storing information to other equipment. Detecting callee identification information from the signal received by the output means capable of outputting the output means, the notification means for notifying the outside, and the receiving means, and comparing the detected callee identification information, When it is detected that the two are in a predetermined correspondence relationship, the calling device identification information sent together with the called identification information is stored in the storage device, and the notification means is caused to make a notification. The wireless paging device is equipped with a control means for controlling the calling device identification information held in the storage device to be outputted from the output device.

(Operation) Therefore, the first and second inventions achieve the above object by providing an output means capable of outputting self-identification information or received calling device identification information to another device.

(Example) The present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of a paging receiver which is a radio paging device of the present invention. First, a radio wave modulated by a paging signal received by a receiving antenna 1 is demodulated by a receiving circuit (RX) 2. This demodulated signal is input to the control circuit (CONT) 3 and temporarily stored. The control circuit 3 then reads its own specific number information, for example, the ID code here, stored in advance in the ROM 4, and determines whether it matches the temporarily stored demodulated signal (calling signal). If it is determined that they match, the control circuit 3 controls the speaker 8 to emit a ringing tone using a tone signal. On the other hand, this paging receiver has
Input terminal 6 for reading the memory contents of ROM4
and an output terminal 7 are provided, and when a read pulse signal is input from the input terminal 6, the read conversion circuit 5 reads out the storage contents (ID code) of the ROM 4 in synchronization with this pulse signal. The read conversion circuit 5 also converts the parallel signal (ID code) read from the ROM 4 into a serial signal and sends it to the output terminal 7. Therefore, output terminal 7
The ID code can be read from the ROM 4 via the ROM 4.

In FIG. 1, components that are not directly related to the circuit configuration, such as a battery as a power source, are omitted. Furthermore, the means for reading out the memory contents of the ROM4 is not limited to the above-mentioned method; for example, all input/output terminals of the ROM4 may be connected to the connector of the paging receiver casing and read directly, or a method using magnetic coupling may be used. Something like that would be fine. Further, the read conversion circuit 5 may also be used as a content read circuit of the ROM 4 included in the control circuit 3, or the ROM 4 may be externally writable.

FIG. 2 is a diagram showing a paging system to which the paging receiver, which is an embodiment of the present invention shown in FIG. 1, can be applied. The paging system according to this embodiment is used, for example, in a large factory, and the central control unit 10 receives a selection signal for calling the paging receiver 91 from the wired telephone terminal 13 via the wired telephone line 16, for example. ,
The paging transmitter TX11 is driven to transmit a modulated wave a modulated with a signal (calling signal) containing the ID code of the paging receiver 91 from the transmitting antenna 12, and the ID code and the number of the wired telephone terminal 13. Store information in internal memory.

Upon receiving this modulated wave a, the paging receiver 91 emits a ringing tone as described above. The user then learns that there is a call, goes to the nearest wired telephone terminal 15, and inserts the paging receiver 91 into the paging receiver insertion slot provided on the wired telephone terminal 15. At this time, the input/output terminals of the paging receiver 91 are connected to the input/output terminals of the wired telephone terminal via a connector. When the wired telephone terminal 15 detects through a switch or the like that the paging receiver 91 has been inserted into the socket, it operates, for example, an automatic dialing circuit to automatically call the central control unit 10 and connect the paging receiver. sends a signal indicating that the In response, the central controller 10 transmits a readout pulse signal via the wired telephone line 18 to the wired telephone terminal 1.
5 supplies this pulse signal to the input terminal of the paging receiver 91. The read ID code is sent to the central controller 1 via the wired telephone line 18.
0, and the central control unit 10 determines whether or not this ID code matches the previously stored ID code. If it determines that they match, the central control unit 10 determines whether or not this ID code matches the previously stored ID code. Terminal 1
3 and automatically calls wired telephone terminals 15 and 13.
Make a line connection. Such a central control device 10
This function can be easily realized by changing the program of currently used electronic switching equipment.

In this way, according to this paging system,
Users of the paging receivers 91 and 92 do not need to memorize the contact's telephone number or perform any dialing operations, and are automatically connected to the contact, making it easy to make semi-two-way calls. .

The user's location can also be registered in the central control device 10 by inserting the paging receivers 91 and 92 into the wired telephone terminals 13 to 15 at each destination. That is, the paging receiver 9
Since the central control unit 10 can grasp which wired telephone terminal 13 to 15 the paging receivers 91 and 92 are plugged into, selective calling of the paging receivers 91 and 92 from other wired telephone terminals 13 to 15 is possible. When this occurs, the central control unit 10 can directly call the wired telephone terminals 13 to 15 to which the paging receivers 91 and 92 are plugged, without calling them via the wireless circuit. It becomes possible. Further, it is also possible to obtain only the position information, that is, the number information of the wired telephone terminals 13 to 15 from the central control device 10. Therefore, for example, when a user is located in a place where radio wave propagation conditions are extremely poor (such as a shielded room in an underground meeting room), this method is convenient and efficient.

FIG. 3 is a diagram showing another paging system, and the same main parts as in FIG. 2 are given the same reference numerals.
The explanation will be omitted. In this embodiment, wireless terminals 30 and 40 are provided in addition to the wired telephone terminals 13 to 15, and the wireless terminals 30 and 40 and the wired telephone terminals 13 to 15
This system enables calls between 19,2
0 is the transmitter/receiver for making this call, and 21
is a distribution combiner, which distributes the signal received by the antenna 22 to the transceivers 19 and 20, combines the output signals from the paging transmitter 11 and the transceivers 19 and 20, and transmits it from the antenna 22. . Further, the wireless terminals 30 and 40 are used in a fixed or portable state, and are equipped with an AC power source.
41 is its antenna.

First, the paging receiver 9 receives a selective call.
1, for example, the nearest wireless terminal 40
Insert this paging receiver 91 into the paging receiver insertion port of. Then, the wireless terminal 40 detects this, drives a read pulse signal generation circuit inside the terminal, supplies this pulse signal to the paging receiver 91, and reads out the ID code. After that, the wireless terminal 40 uses this read ID.
A coded control signal is transmitted via the antenna 41. This control signal is received by either the transmitter/receiver 19 or 20 via the antenna 22 and the distributor/combiner 21, and is sent to the central control device 10.
Thereafter, communication control is performed in the same manner as in the above-mentioned paging system, and a telephone line is established between one of the wired telephone terminals 13 to 15 that called the paging receiver 91 and the wireless terminal 40 into which the paging receiver 91 is inserted. This enables semi-two-way communication.

In the above-mentioned embodiments, the paging receivers 91 and 92 read out the ID code from the ROM in which the ID code is stored in advance. It may also be one that reads the contents of the RAM that is stored.

That is, to explain such a case with respect to the paging system shown in FIG.
The number information of the wired telephone terminal 13 that made the call is transmitted to the paging receiver 91, and the paging receiver 91 receives the number information.
Store in RAM. And paging receiver 9
1 into the wired telephone terminal 15, the central control unit 10 reads this number information via the wired telephone terminal 15 and performs call control.

Further, the connection between the paging receivers 91, 92 and the wired telephone terminals 13 to 15 or the wireless terminals 30, 40 is by plug-in connector connection, but is not limited to this. Any method may be used as long as it can read the contents of the ROM.

Furthermore, it is also possible to use the paging receivers 91 and 92 in a system other than a paging system, such as a cache dispenser, simply as an ID code storage device.
