That is, the connection control means 14 instructs the switch controller 5 to set a route from the telephone 1 to the subscriber circuit 61 to the switch 4 to the outgoing trunk 71 to the line 3.

[Problem to be solved by the invention]

Since the conventional line reservation device is configured as described above, when making a line reservation for the blocked line 3, the telephone 1 does not have information that informs how many line reservations are waiting at that time. Since the caller is not sent, and only a dial tone is sent back, there is a problem in that the calling party does not know when the line 3 will be available, requiring an unnecessary waiting time for the call.

This invention was made in order to solve the above-mentioned problems, and aims to provide a line reservation device that notifies the line reservation connection order in advance and allows the calling party to select whether or not to make a line reservation based on the notification. purpose.

[Means to solve the problem]

The line reservation device according to the present invention includes a counting means for counting the number of waiting line reservations registered in a storage device, and connection order information based on the count value of this counting means when the line reservation is made. At the same time, the receiving means has a function of receiving registration information indicating whether reservation registration is necessary or not, which is returned from the terminal device in response to the connection order information. It is something that has been set.

[Effect]

The line reservation device according to the present invention, when a line reservation request is received from a terminal device when the line is busy, cancels the number of requests in order, and transmits connection order information based on the counted value to the terminal device that requested the line reservation. By having the caller select whether or not to register for a reservation based on the connection order information, and registering only the requested line reservations in the storage device, the caller can make reservations without knowing when the line will become available. To realize a line reservation device that does not cause a caller to keep waiting unnecessarily.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 8 is a central control unit, 9 is a storage device, 10 is a processor bus, 12 is a memory access means, 13 is a call/notification means, and 14 is a connection control means. The detailed explanation will be omitted since it is the same or equivalent to those in .

Further, reference numeral 15 is a counting means for counting the number of waiting line reservations registered in the storage device 9. 16 generates connection order information based on the count value of this counting means 15, that is, the number of line reservations that are waiting (in progress) at that time, when a new line reservation is generated from the telephone set 1;
This is a turn notification means that notifies the telephone 1 that has requested the line reservation of this. The 1T also has a function of receiving registration information, which is returned from the telephone 1 in response to the connection order information sent from the order notification means 16, and indicates whether or not to register a line reservation. Conventional receiving means 11 shown in FIG.
and using a different receiving means.

Next, the operation will be explained. If the line 3 is blocked when a call is made from the telephone 1 and a call is made again, a dial tone is sent to the telephone 1 from the signal tone trunk T2 in the same way as in the conventional case. When a line reservation instruction signal is sent from the telephone set 1 in response to this dial tone, in the central control unit 8, the reception means 1T receives the signal as in the conventional case, and the memory access means 12 receives the line reservation instruction signal. It is temporarily written to the storage device 9. At this time, in the central control unit 8, the number of line reservations for this line 3 is counted by the counting means 15, and the counted value is also written into the storage device 9.

The counted value of this counting means 15 is also sent to the order notifying means 16, and the order notifying means 16 generates connection order information based on the received counted value and sends it to the telephone 1 that requested the line reservation. do. The caller who made the call from the telephone set 1 decides whether or not to register the line reservation based on the sent connection order information, and returns registration information indicating pros and cons of the registration.

This registration information is generated, for example, by simply going on-hook to cancel a line reservation, and by pressing a reservation button provided on the telephone 'Ia1 to request registration of a line reservation.

The central control device 8 receives this registration information through the receiving means 17.
If the registered information is for canceling the line reservation,
The memory access means 12 deletes the line reservation and its connection order once written in the storage device 9, and also decrements the count value of the counting means 15. Also,
If the registration information requests the registration of a line reservation, the line reservation and its connection order written in the storage device 9 are registered as they are, and the count value of the counting means 15 is also saved as is. When the registration in the storage device 9 is completed in this manner, the central control unit 8 sends the reservation acceptance tone back to the telephone set 1 from the signal tone trunk 72 as in the conventional case. The telephone set 1 goes on-hook upon receiving this reservation acceptance tone, and the series of line reservations is completed.

After that, when the Trunk Mosier Lua detects that the line 3 is vacant, the memory access means 12 accesses the storage device 9, and if the line reservation is registered, the calling/notification means 13 first uses the line 3. Make 3 reservations. Next, the subscriber circuit 61 makes a call to the telephone 1 that requested the line reservation that is the earliest in the connection order. When the telephone 1 answers, the central control unit 8 controls the switch controller 5 and the trunk mosi-luer in accordance with instructions from the paging/notifying means 13, as in the conventional case, and sends the telephone 1 a signal tone trunk T2 and a multi-line 3. A signal tone will be emitted to let you know that the space is vacant. When the dialing information of the destination is transmitted from the telephone 1 that received this signal tone, the signal tone is stopped as in the conventional case, and the telephone 1 is output to the trunk 7.
Connect to line 3, which was on hold from line 1.

In addition, in the above embodiment, line reservation was explained when the line (dedicated line) between exchanges is blocked in a private branch exchange, etc., but it may also be used as a central office line to a public network. It has the same effect as.

〔Effect of the invention〕

As described above, according to the present invention, when a line reservation is requested, the number is counted, connection order information for the reservation based on the counted value is returned to the terminal device that requested the line reservation, and the connection order information is Since the configuration is configured such that the line reservation is registered based on the registration information sent from the terminal device, the caller knows the 1W4 check until connection when the line reservation device is connected, and can decide whether or not it is necessary to register the line reservation. This has the effect of providing a line reservation device that does not keep waiting unnecessarily without knowing when the line will become free.
