JPS62139457A - Terminating subscriber tracking system - Google Patents

Abstract

PURPOSE:To terminate a telephone set arranged near a terminating subscriber even if the terminating subscriber exists in any position by registering the telephone number of the telephone set arranged near the position and the logical number of the terminating subscriber by an optional telephone set at any time. CONSTITUTION:When a general subscriber SUB-A has something to contact with Mr. B in visiting an enterprise C and informs the name B through a telephone, an operator dials the logical number corresponding to the visitor B from an switchboard OP on the basis of a visitor list to track and terminate the access automatically to the destination of the visitor. When the visitor B dials a specific number XXX, the logical number 800 and extension number 320 to be terminated for instance, these numbers are registered in a terminated extension number registering table. In case of termination to the logical number 800, the number 320 is extracted from the registered table and termination to the extension number 320 is executed.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an incoming call connection system in an electronic exchange, and in particular to an incoming call connection system in which a call to a called party is received at a telephone set near the location of the called party. This is related to the person tracking method.

[Background of the invention]

Up until now, this type of call receiving service in electronic exchanges has been based on the so-called call forwarding method, in which when a telephone subscriber temporarily moves to another specific location, the incoming call to the corresponding telephone is forwarded to the telephone at the new location. It has been known. However, this method has the problem that the transfer target is limited to telephones and cannot be used effectively for specific individuals. In addition, those related to this type of incoming call service include:
For example, there is a service described in Japanese Unexamined Patent Publication No. 125758/1982, but the service is limited to specific people who share the telephone, and the service to unspecified visitors from outside is not considered. .

[Purpose of the invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a terminating subscriber tracking system that allows calls to a terminating subscriber to be terminated at telephones near the terminating subscriber's location, no matter where the terminating subscriber is located.

[Summary of the invention]

For this purpose, the present invention allows the telephone number of a telephone near the recipient's location and the logical number given to the called party to be registered from any telephone at any time. As a result, the call to the called party is received by the telephone set whose telephone number is registered as a pair with the logical number.

[Embodiments of the invention]

The present invention will be explained below with reference to FIGS. 1 to 4, taking a private branch exchange (PBX) as an example.

According to the present invention, when there is a visitor in a company having a private branch exchange (PBX), the visitor group and the logical number for this visitor are registered in advance at the reception desk. As shown in FIGS. 2(a) and 2(b), a visitor list is created in which visitor groups and logical numbers correspond. This may be registered in the PBX itself using a data tyrator, or may be recorded off-line in a ledger or the like.

From now on, the visitor will use this logical number to register an extension number at the place he/she visits. If there are multiple places to visit, the registration is changed each time at each place. Now, as shown in Figure 1, general subscriber 5UB-
If A has something to do with Mr. 8, who is visiting company C, and calls company C and tells his name B, the operator should
), by dialing the logical number corresponding to the visitor from the switchboard OP according to the visitor list shown in (b),
The call can be automatically traced to the visitor's destination.

The outline of the present invention has been described above, but a more detailed explanation will be given below.

In other words, FIG. 3(a) shows the flow of the destination extension number registration process.
0. Registration is performed by dialing the destination extension number 320 in order. When the special number identifies the destination extension number registration process, the next step is to determine whether there is a logical number, but if there is no logical number, the process is to connect to a BTT (busy tone trunk). be. If yes, the logical number 800 is used in Figure 3 (b
), the destination extension number registration is Cheagle C3TDN.
The destination extension number 320 is registered in the position corresponding to the logical number aOO. Fig. 4 shows the flow of extension call processing. When a call is made from an extension telephone, it is first determined whether the call is to a logical number or not. If it is not, a K is sent to direct the call to the normal extension. However, in the case of an incoming call to a logical number, the destination extension number is extracted from the previously registered destination extension number registration table C3TDN using the logical number, and the call is received to that destination extension number. be.

By giving a logical number to a visitor in this way, a visitor can register and change the visited extension using the visited extension with his or her own logical number, and only the visitor's logical number can always be used to register and change the visited extension. It will be possible to track and receive calls to the network, thereby improving the exchange service. Further, even when an operator or the like intervenes, it is only necessary to focus on the logical number of the visitor, and the effect of simplifying the switchboard service can also be obtained.

The present invention has been explained above using a private telephone exchange as an example.
It can also be applied to general telephone exchanges. For example, the telephone number of a fictitious telephone is registered in the exchange as a logical number, and the receiving subscriber registers the telephone number of the destination as updatable using the logical number. Therefore, if a third party dials the logical number, the call to the terminating subscriber will be terminated at the telephone set at the terminating telephone number.

As can be seen from the above, no telephone is actually connected to the logical number, making it unnecessary to install barware such as a telephone, making it possible to provide a tracking and receiving service very economically.

〔Effect of the invention〕

As explained above, in the case of the present invention, the location of the called subscriber is registered each time, so no matter where the called subscriber is, a call to that subscriber is received at a telephone set near that location. It has the effect of being
