Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Use of the Invention] The present invention provides a plurality of called numbers to the same called line or terminal of an exchange and provides various services according to the status of the line or terminal. The present invention relates to a terminal connection control method suitable for doing so.

[Background of the Invention]

The conventional terminal connection control method is the SE-136 report of the Institute of Telecommunications Engineers.
As described in "Concept of user-friendly intelligent exchange service", the system side indicates whether to use interrupt, message, call back, or transfer when the other party talks or does not respond for a certain period of time. The user can select it, or the system can automatically select it and guide the user to the desired menu. This will be described with reference to FIG.

In FIG. 3, when the caller dials the called number XB, the state of the called terminal XS corresponding to the number is confirmed as is known. If the called terminal XS is busy, a busy tone (BT) is sent to the caller XA. Here, the sender XA designates one of XC, XD, and XE as the service to be taken next by hooking and dialing. For example, when XC is specified, it interrupts the called terminal XS, when XD is specified, it connects to the message device TKE and blows in the message content, and when XE is specified, it transfers and connects to the pre-registered transfer destination XT. .

This conventional terminal connection method is very difficult to use because it is a method in which only one called number is given to the same terminal, and the called terminal is notified of the status of the called terminal after access. That is, in the conventional method, the exchange notifies the caller of the status of the called party, and the caller instructs the desired service by dial operation, etc. Therefore, the caller needs to make a hooking + dial after distinguishing the signal tone. However, the operability is poor, and the exchange is complicated because it accepts dials and controls signal sending. In other words, referring to the example in FIG. 3, when the caller XA hears the busy tone BT and then hooks, and when a blank number is dialed instead of the normal dial, the caller XA hears the busy tone again to redial. Later, a very complicated operation is required, such as hearing the original busy tone BT, hearing the dial tone after hooking, and then redialing.
Therefore, even if various functions are prepared, it is often not used.

[Object of the Invention]

An object of the present invention is to provide a terminal connection control system that can receive various services without complicated exchanges with exchanges.

[Outline of Invention]

In order to achieve the above object, in the present invention, a plurality of called numbers are given to the same line or terminal, and the calling number is given in advance to the exchange by the called number corresponding to the called party situation and service. By doing so, the exchange will provide the desired service according to each situation.

Example of Invention

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, a sender XA, a called terminal XS, and a message device TK.
E and the transfer destination terminal XT are connected via the connection links a, b, and c of the exchange switch SW, respectively. The called terminal XS is provided with a plurality of called numbers XB, XC, XD, XE for instructing the service to be taken according to the situation of the called terminal XS or the called party,
In particular, the number "X" is a part that specifies the called terminal XS, and the remaining numbers "B to" E "are parts that specify the service content. Here," B "to" E "are It is possible to give a common number to other called terminals.

The connection of the exchange switch SW is controlled by the processing device CC based on the operation of the translator TLR. The translator TLR has a number expansion X for limiting the line or terminal from the called number and confirming its status, and a status confirmation unit STU, and further specifies the service of the called numbers XB to XE. Part S "B" to "E" for developing service contents, and the status confirmation part STU called terminal status (eg BLSY) and service specification information from part S (eg "B"). ~ "E") has a determining unit U for determining the service content. The deciding unit U responds to the service designation information "B", "C", "D", "E" from the Tori-S by "sending a busy tone to the caller" and "interrupting the called terminal XS", respectively. ”,“ Message to message device TKE ”,“ Transfer to terminal XT ”
And sends the determination result to the processing device CC, and the processing device CC uses the determination result to establish the connection links a, b, c of the exchange switch SW.
Select.

Next, the connection operation of FIG. 1 will be described with reference to the flowchart of FIG.

The caller XA determines in advance what kind of service (for example, interrupt or transfer) is to be received when the called terminal or called party is in various situations (for example, the called party is busy or absent), and Dial one of the called numbers XB to XD corresponding to the service. For example, if the number XB is dialed, the busy tone BT is returned to the caller XA when the called party is busy. As shown in FIG. 1, the processing device CC has a known number.
When XB is received, the called number XB is sent to the translator TLR, and the translator TLR uses the number expansion X to call the called terminal X.
S is determined, and the status confirmation unit STU confirms the status of the called terminal XS or the called party. Based on this result and the number "B" of the service designation portion of the called number from Tori-S, the service content (returning busy tone to XA) is determined. Based on this, the processor CC sends a busy tone to the caller XA as is known.

When the number XC is dialed instead of the number XB, the status of the called terminal XS or the called party is confirmed by the number expansion X and the status confirmation unit STU in the translator TLR as described above, and the status of the called terminal XS or the called party is confirmed. As a result, the service content determination unit U determines the service content (for example, BREAK IN: interrupt). Based on this, the processor CC interrupts the caller XA via the link a to the called terminal XS. At this time, the interruption tone is transmitted to the caller after the busy tone is transmitted for a certain period of time.

If the number XD is dialed instead of the number XB, the translater TLR receives the called number XD, and the service contents (message service) are received by the number expansion X, the status confirmation unit STU, the tri-S and the determination unit U described above. Is determined and the determination result is sent to the processing device CC. Based on this, the processing device CC first sends a message sound to the caller XA and then connects the caller XA via the message device TKE link b. The caller recovers after sending the message to TKE.

When the number XE is dialed instead of the number XB, the number of calls X is expanded in the translator TLR, the status confirmation unit STU, the tri-S, and the decision unit U are called depending on the situation of the called party. The service content (for example, transfer) is determined according to the situation of the caller, and based on this, the processing device CC connects the caller XA to the transfer destination XT via the link c. Prior to this, the transfer sound is returned to the caller XA for a certain period of time. Thus, the caller XA does not need to confirm the status of the called terminal during the connection and instruct the exchange about the service to be taken next.

In the above embodiments, a method of giving a called number by a plurality of services corresponding to one called party has been described. However, a plurality of called parties are provided for the same line or terminal, and the number is different for each called party. On the other hand, it is possible to give the number of called numbers corresponding to the plurality of services. In this case, it becomes possible to provide a detailed service for each called party. It is also possible to make a part of the called number a service corresponding part and use this part as a number common to each called party so that the calling party's number can be easily stored.

〔The invention's effect〕

As described above, according to the method of the present invention, a plurality of numbers are given to the called line or terminal, and the service to be taken according to the situation of the called line or terminal or the called party By providing the exchange with the called number in advance from the caller in correspondence with the called number, it is very easy to provide detailed services corresponding to the situation of various called parties without complicated operations. You can do it.

Also, by making a part of the called number a designated part corresponding to the service contents according to various situations of the called party, and making this part a number common to all called parties, it is easy for the caller to remember. It is possible to provide a terminal connection control method that is even easier to use as the called number.
