Abstract

PURPOSE:To attain an efficient call while eliminating ineffective shart of a radio base station by designating a call zone so as to prevent a call at a zone where no subscriber exists. CONSTITUTION:A caller request party 1 raises a call, a call comes to a radio call exchange 5, a reception trunk 7 is connected and a call number is received. The number is confirmed by a central controller 8 and stored in a call number storage section 10 of a main storage device 9. When the controller 8 discriminates it as the absence of an additional number, the controller 8 reads all digits of the call number from the storage section 10, uses the number as an index to make a call, and when the call zone registered in advance in a zone storage section 11 is known, and an outgoing trunk 15 of said zone A and a radio base station 13 are detected. Then a call number is sent immediately to a signal device 17 to connect the signal device 17 and the outgoing trunk 15. The signal device 17 converts the call number into number information used by a radio line 18 and it is sent to the base station 13 via the outgoing trunk 16. Thus, the radio call is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio paging system, and more particularly to a radio paging system that can specify a paging area.

[Conventional technology]

In the conventional radio paging system, a calling subscriber's paging request is input directly from the subscriber or via a handler, and the radio paging switch uses radio base stations in all areas that can be called or stores information in advance in the switch. A radio base station in a specific area that has been set up is selectively used to call a called subscriber.

[Problem that the invention seeks to solve]

In the conventional radio paging system described above, the radio paging exchange always fixed the paging area, so paging information was sent to a radio base station in an area where there was no called subscriber. Even if a subscriber exists and needs to be called, the line or other equipment may become too cold when the call is needed, or the call may be delayed significantly, or the number of devices required to make the call may increase. There is a problem in that various types of waste occur.

An object of the present invention is to limit calls to areas where the calling subscriber really needs to receive calls, thereby
An object of the present invention is to provide a wireless paging system that eliminates various wastes and makes effective use of wireless lines.

[Means for solving problems]

The radio paging system of the present invention is a radio paging system in which a radio paging exchange receives a calling number from a call requester and calls the called subscriber via a wireless line, in which the called subscriber is registered in advance in the radio paging exchange. a paging region storage section for storing a paging region that has been called; and a paging region detection section that detects a paging region specified by an additional number following the calling number from the call requester; If only the calling number is to be sent, the wireless paging exchange reads the calling area from the calling area storage unit based on the calling number, selects a wireless base station in the corresponding calling area, and sends the calling number information to the wireless base station. When the calling subscriber is called by the wireless line and the call requester specifies the calling area by the additional number following the calling number, the wireless paging exchange calls the calling subscriber specified by the additional number. detecting the area by the calling area detection unit;
The apparatus is configured to select a wireless base station in the detected calling area, send calling number information to the wireless base station, and call the called subscriber over the wireless line.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a system to which the present invention is applied. When the call requester 1 calls a called subscriber having a call receiver 2 or 3, the call requester 1 dials the station number including the wireless call exchange 5, and then dials the calling number and then adds another number. Dial the number. This call request arrives at the incoming trunk 6 of the wireless paging exchange 5 via the subscriber line exchange 4 in which the call requester 1 is accommodated. Call requests from ranks 1 to 6 are received and connected to trunk 7. At reception, the trunk 7 receives the calling number dialed by the call requester 1. The received calling number is checked by the central controller 8 digit by digit and stored in the calling number storage section 10 included in the main storage device 9 . After the trunk 7 receives all the digits of the calling number, the additional number is sent, so the reception is held for a certain period of time, and when the additional number is received, it is sent to the central control unit 8. The central control device 8 also stores the additional number in the confirmation role calling number storage section 10. Even if the central control unit 8 waits for a certain period of time, whether or not an additional number is sent, it immediately starts the next operation if it receives all the digits of the additional number.

If there is an additional number, the additional number is read from the calling number storage unit 10 and compared with information stored in the calling area detecting unit 12 to determine the calling area, that is, the radio base station. If there is no additional number, the calling number is read from the calling number storage section 10 and compared with the information stored in the calling area storage section 11 to determine the calling area, that is, the radio base station.

For example, if the calling area is C area, wireless base station 13.1
4 is selected and decided, and if it is the calling area or area A, the radio base station 13 is selected and decided.

When calling region C, the central control device 8 connects the outgoing trunk 15.16 and the signal device 17 in order to send a paging signal to the radio base station 13.14 in the called region.
The wireless base stations 13 and 14 are activated, and the calling number is read from the calling number storage section 10 and sent to the signal device 17. The signal device 17 transmits the calling number received from the central control unit 8 to the radio line 18.
10 is converted into calling number information used when making a call, and sent to the wireless base station 1 via outgoing trunks 15 and 16.
Send on 3.14. The radio base stations 13 and 14 put the received call number information on a carrier wave and call the call receiver 2 or 3 via the same lines 18 and 19. This allows the calling subscriber to receive a call even if he or she is in area A or area B.

Next, the operations of the calling number storage unit 10, calling area storage unit 11, and calling area detection unit 12 included in the central control unit 8 and main storage device 9, which constitute the present invention, will be explained using the flowchart in FIG. explain. The operation of this device is performed according to the processing procedure described above.

As an example, a case where a calling subscriber is registered in area A will be explained.

1st step> Receiving the calling number The call is received by the radio calling exchange 5 by the call requester 1, and is connected to the reception trunk 7. Receptionists 1 to 7 receive the calling number from call requester 1. The received calling number is checked one by one by the central controller 8 and stored in the calling number storage section 10 of the main storage device 9. Upon receiving the predetermined number of digits as the calling number, the first step is completed and the central controller 8 enters the next step.

(Second stage) Detection of the calling area After receiving all digits of the calling number, the central control unit 8
The connection line between the call requester 1 and the call requester 1 is maintained for a certain period of time. If you receive an additional number while holding the connection,
The central control unit 8 also checks this one digit at a time and stores it in the calling number storage section 10 following the previously stored calling number.

If the first digit of the additional number is not received even after a certain period of time has passed after receiving all the digits of the calling number, the central control device 8 determines that there is no additional number and returns the calling number stored in the calling number storage unit 10. All digits of the number are read out, and the calling number is registered in advance in the calling area storage unit 11 as an index to know the calling area and to call out to the corresponding area A.
15 and the wireless base station 13 are detected.

Even though this called subscriber is registered in area A, it is clear that he is currently in area B, so if he calls with an additional number for calling area B, all digits of the additional number will be received immediately. All digits of the additional number are read from the calling number storage section 1o, and the outgoing trunk 16 and radio base station 14 in the corresponding area B are detected by the calling area detection section 12 using the additional number as an index.

(Third stage) Sending of calling number information If it is determined that there is no additional number, the central controller 8, once the outgoing trunk 15 and wireless base station 13 have been determined, immediately selects the signal device 17 and sends the calling number. 17 and the outgoing trunk 15 are connected.

Also, if the outgoing trunk 15 is captured, the wireless base station 1 is automatically
3 is activated and prepares to send out a calling signal.

When the above preparations are completed, the signal device 17 converts the calling number into calling number information used by the wireless line 18 (signal formats mainly used include voice signaling and digital signaling), and outputs the signal. By sending the signal to the wireless base station 13 via the trunk 15, the operation as the wireless paging exchange 5 is completed.

When calling a called subscriber in area B using an additional number, the operation is similar to that described above, except that the outgoing trunk 15 is changed to 1b, the wireless base station 13 or 14, and the wireless line 18 is changed to 19, and there is no other explanation. Since they are the same, their explanation will be omitted.

Finally, the operation of registering a calling area will be explained using the flowchart of FIG. First, the calling area, which was declared by the calling subscriber himself or herself at the time of starting the wireless calling service, is inputted by the operator or the operator's terminal device 20. After the input information is confirmed by the central controller 8, it is stored in the calling region storage section 11 included in the main storage device 9.

[Effects of the Invention] As described above, the present invention specifies the calling area, thereby preventing calling in areas where no calling subscriber exists. Therefore, it is possible to eliminate invalid activation of wireless base stations, and depending on the combination of calling areas, it is also possible to call more than 2 Å calling subscribers at the same time, which improves calling efficiency and improves service. This has the effect that it is possible to reduce the number of devices required for this purpose.
