Abstract

PURPOSE:To allow the system to be communicated with a person carrying a receiver even if the person carrying the receiver moves to any service area by providing a frequency setting section and an address transmission section to the receiver and providing a frequency setting section and an address transmission section to a terminal equipment connected to a center via a telephone line. CONSTITUTION:When the person carrying a receiver 1 moves from a resident area A to an area C53, the receiver 1 is inserted to a terminal equipment 2 installed at a station or an air port or the like in the area C to apply registration. The terminal equipment 2 receiving the registration operation uses a frequency control section 21 to control a frequency setting section 12 of the receiver 1 thereby matching the frequency with the reception frequency of the area C53. Moreover, the address data from an address registration section 14 is read by an address transmission section 16 and sent to a terminal equipment 2. The terminal equipment 2 receives the data at its address reception section 22 and sends the data to the center 3 via a telephone line and an exchange station 6 from the address transmission section 23. A control section 33 of the center 3 registers the district information of the area C where the terminal equipment 2 exists and the address of the called receiver 1 to a registration section 32.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a paging system for calling a person carrying a receiver such as a pager as needed.

(Prior Art) In conventional paging systems, reception frequencies differ for each service area (district) (for example, the Kanto region) and for each service company.

(Question B that the invention seeks to solve) Therefore, even if you take a pager receiver used in the Tokyo area to the Osaka area, you will not be able to make a call. This is because the receiving frequencies are different in the Tokyo area and the Osaka area.
Another reason is that it is unknown to which service area the pager receiver has moved.

(Means for solving the problem) When activated from the center, a radio wave containing the address of the receiver to be called is emitted from the transmitting station, and the receiver receives this radio wave, including its own address. In a paging system that displays an incoming call when a call is received, the receiver has a frequency setting section that changes the reception frequency by receiving settings, and an address registration section that stores the own address, and sends out the own address to the outside. A frequency control unit that controls the frequency setting unit of the receiver to change the reception frequency to a terminal connected to the center via a telephone line, and an address transmission unit of the receiver. A paging system comprising: an address receiving section that receives an address; and an address sending section that sends the address received from the address receiving section to a center via a telephone line.

(Operation) If the caller sends the address of the receiver to the center, the caller can make a call no matter where the receiver is in the service area.

(Example) First, a conventional paging system will be explained based on FIG.

FIG. 6 shows a conventional paging system. Receiver 10
A receiving frequency is set at which a call can be received within service area A. The caller is now calling the center 30 using the telephone 9, and the receiver 1 is about to call.
Dial the address number 0. The control unit 31 in the center 30 causes the transmitting station 40 to emit a calling radio wave of the receiver 10 to the service area A corresponding to the address number input from the telephone 9.

Receiver 10 detects that its own address number is included in the calling radio wave and generates a ringing tone. The person carrying this receiver 10 can receive contact by calling a predetermined contact number from a nearby telephone 7.

However, the caller is aware that the receiver 10 is in its own service area A.
It was not possible to contact the person carrying this receiver if he was outside the country.

Next, an embodiment of the paging system of the present invention, which eliminates the above-mentioned conventional drawbacks and further improves it, will be described in Sections 1.3.4 and 5.
Explain based on the diagram.

FIG. 1 is a block diagram of a pager receiver and a terminal according to an embodiment of the present invention. FIG. 3 is a block diagram of the paging system. Figures 4 and 5 show the contents of the center's registration section.

1 is a pager receiver (hereinafter referred to as a receiver), 2 is a terminal, 3 is a center which is a control station, 4 is a transmitting station, 5 is a service area (hereinafter referred to as an area), 6 and 8 are switching stations,
7 and 9 are telephones.

First, the receiver 4, terminal 2, and center 3 will be briefly explained.

The receiving section 11 of the receiver 1 inputs the radio wave received by the antenna 17 and the frequency output from the frequency setting section 12, performs demodulation operation, and sends the demodulated data to the address verification section 13. The address matching section 13 matches the input data with the own address data from the address setting section 14,
If they match, the display unit 15 will display the information. This display includes ringing, flashing display of the issuing diode, vibration, etc.

The terminal 2 is installed at a station, airport, etc., and is connected to an exchange 6 through a telephone line.

When the center 3 receives a call via the switching center 8 from a caller who wants to call the person carrying the receiver 1, the center 3 checks whether the receiver 1 has moved to an area other than the area where the receiver 1 is permanently stationed. 32 registered address data is searched. If the receiver is not registered, the address data of the receiver to be called is sent to the transmitting station 4 in the resident area, and if it is registered, it is sent to the transmitting station 4 in the registered area. Any transmitting station 4 that receives this data modulates this address data and emits it as a radio wave from an antenna.

Next, a description will be given of the registration operation and calling operation when the person carrying the receiver 1 moves from the area where he or she always resides (for example, area A) to area C53.

The person carrying the receiver 1 inserts the receiver 1 into a terminal 2 installed at a station or airport in area C and performs a registration operation. When the terminal '2 receives the registration operation, the frequency controller 21 receives the signal. The zero frequency setting section 12 that controls the frequency setting section 12 of the machine I to match the reception frequency of the area C53 is set to P L
In the case of an L (Phase-1 oched 1 loop) circuit system, the output of the frequency control section 21 may provide a frequency division input to a programmable divider. Further, the address data from the address registration section 14 is read out to the address sending section 16, and further sent from the address sending section 16 to the terminal device 2. The terminal 2 receives this address data at the address receiving section 22 and then automatically dials the address data to the center 3.
After calling the address sending section 23, the telephone line,
It is sent to the center 3 via the switching station 6.

In the center 3, the control unit 33 registers the district information of the area C where the terminal 2 is located and the address of the receiver 1 to be called in the registration unit 32 as shown in FIG. Note that this registration operation is performed when the area to be registered is different from the area where the receiver is resident. This will be explained below.

This completes the registration operation.

Next, the operation in which the caller calls the person carrying the receiver 1 who has moved from area A51 to area C53 will be explained.

The caller calls the center 3 from the telephone 9, and further sends to the center 3 the address number of the receiver 1 to be called. Then, the control unit 33 of the center 3 converts the address number into address data, and further searches the registration unit 32 to see if the same address data is registered. If the same address data as the input one is registered, the control unit 33 moves to area C53 shown in FIG.
data is read out, a line connected to the transmitting station 4 in area C corresponding to this data is selected, and the address data of the receiver to be called is sent to this line. The transmitting station 4 in area C receives and modulates this address data, and then emits it as a radio wave from an antenna. Receiver 1 receiving a call
exists in area C, and the frequency setting section 12 has already received the setting from the terminal 2 and has been set to correspond to the reception frequency of area C. Therefore, the receiving section 11 of the receiver 1 receives the output from the frequency setting section 12, and the transmitting section 4 receives the output from the frequency setting section 12.
Address data can be detected by receiving and demodulating empty radio waves. The address verification section 13 collates this address data with the address data from the address registration section 14, and if a match is determined, causes the display section 15 to beep or, if equipped with an indicator, to blink the light emitting diode.

The person carrying the receiver 1 who receives the call can be contacted by calling a predetermined contact number from a nearby telephone 7.

Next, the person carrying receiver 1 moves from area C53 to area B52.
Then, the controller 33 of the center 3 finds that the sent address data matches the address data registered in the registration unit 32. Search to see if something is available. In this case, since the address data of the receiver 1 has already been stored in the registration section 32, the corresponding destination area column shown in FIG. 4 is rewritten from area C53 to area B52.

Therefore, when the receiver l receives a call from the next time, the center 3 causes the transmitting station 4 in the area B to emit a radio wave for the call.

Furthermore, area A5 where the person carrying receiver 1 is resident
Return to step 1, set it on terminal 2 in the area, and perform the operation. Then, the control unit 33 of the center 3 searches to see if there is a match between the sent address data and the address data registered in the registration unit 32. In this case, since the address data of receiver 1 has already been stored,
Select area B in the destination area column shown in the corresponding figure 3.
52 to area A51, but since data indicating that receiver 1 is included in area A is included in the address data, data registration of the corresponding receiver shown in Figure 3 is necessary. Delete everything.

Therefore, if there is a call to the receiver 1 from now on, the center 3 will control the transmitting station 4 in area A51, and will emit the calling radio wave from there.

FIG. 2 is a block diagram of another embodiment of the receiver 1 and the terminal 2. In FIG. Here, the receiver 1 includes a wireless transmitter/receiver 18, so that settings can be made in the receiver 1 without contact between the receiver 1 and the terminal 2.
The terminal device 2 is provided with a wireless transmitting/receiving section 24. To make desired settings for the synthesizer, which is the frequency setting section 12 of the receiver 1, a control signal from the frequency control section 21 of the terminal 2 is emitted as a radio wave from the transmitting/receiving section 24. Transmitter/receiver section 1 of receiver l
At step 8, the receiver extracts a control signal from this radio wave, and then sets the synthesizer to the desired frequency. On the other hand, in order to transmit the address of the receiver 1 to the terminal 2, the address from the address transmitting section 16 is transmitted by radio waves from the transmitting/receiving section 18. Furthermore, the transmitting/receiving section 24 of the terminal device 2 which receives this radio wave sends the address to the address receiving section 22. As described above, the receiver 1 and the terminal 2 transmit and receive signals wirelessly.

The terminal 2 connected to the telephone line captures the frequency setting and telephone line based on the area where the terminal 2 exists only when the charge or telephone card is inserted, similar to a public telephone, and connects to the center 3 by automatic dialing. and the address of receiver 1.

The receiver 1 has a display section capable of displaying numbers,
The control unit 33 of the center 3 transmits the calling number data obtained from the calling party shown in FIG. 5 and random additional number data set each time the receiver 1 is called, together with the receiver address data. After being modulated by the station 4, it is emitted as a radio wave from the antenna.

Receiver 1 that receives the call displays the calling party number and additional number on display unit 15. The person carrying this receiver 1 calls the center 3 from the telephone 7 that he or she wants to answer, and
Dial the calling number and additional number displayed in 5.

Upon receiving this, the control unit 33 of the center 3 determines that the input additional number is the same as the one stored in the registration unit 32, calls the telephone with the input calling party number, charges the telephone, and makes the call. The telephone that received the call and the telephone that responded are controlled to be in a conversation state.

The present invention can also be applied as follows.

(1) If data can be sent and received between the terminal 2 and the center 3, the uses of the terminal 2 can be diversified.

(2) In this embodiment, many terminals are installed at stations and airports, but if these are not available, register with the center manually from your phone and manually set the destination area on the receiver. You can.

(3) The address of the registration unit of the center and the information on the destination area may be deleted using a telephone, and the reset button may be operated to return the receiver to the receivable area in the resident area.

(Effects of the Invention) As explained above, the present invention has the effect that it is possible to reliably contact the person carrying the receiver, no matter which service area the person carrying the receiver moves to.
