Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for calling a called subscriber in an electronic exchange.
The present invention relates to a terminating subscriber paging system that allows the originating subscriber to be informed of the status of the terminating subscriber by providing a ``l''.

[Conventional technology]

Conventionally, this type of calling system in electronic exchanges is a system that always issues the same type of calling person (RGT) regardless of the originating subscriber when a connection request is made from the originating subscriber, and a method disclosed in Japanese Patent Application Laid-open No. 117961/1983. As stated in
There is a system in which different ring tones (ROTs) are issued to the called subscriber depending on the calling subscriber number.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology can notify the called subscriber of information about the calling subscriber, but during the same call,
Since the calling subscriber cannot obtain status information of the called subscriber, for example, whether the call is interrupted while the call is busy or whether the call is temporarily unavailable, the calling subscriber may make repeated calls. There was a drawback that it had to be done.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, an object of the present invention is to provide different ring tones (RB) depending on the status of the called subscriber when a call is called.
It is an object of the present invention to provide a terminating subscriber status notification method that allows the originating subscriber to be notified of the status of the terminating subscriber by letting the originating subscriber hear T).

Means for Solving Problem C] In order to achieve the above object, the present invention provides a terminating center exchange with different ring tones (R
B'r)) A function is provided to convert the ring tone trunk type to be heard by the calling subscriber according to the rank and status of the called subscriber, and when there is a connection request from the calling subscriber, the status of the called subscriber is The system converts the call tone into a prespecified special ring trunk type in accordance with the call, and allows the originating subscriber to hear the ring tone transmitted from the ring tone trunk.

[Effect]

At the receiving station, the type of ring tone is specified in advance for each state of the called subscriber, and thereby, in response to an incoming call from the calling subscriber, a special ring tone is sent out depending on the state of the called subscriber.

[Example] An example of the present invention is shown in FIGS. 1 and 2 below. 1st
FIG. 2 is a diagram showing an embodiment of the incoming subscriber status notification system according to the present invention, and shows a relay system when a call is interrupted during a call, and FIG. 2 shows an example of a conversion list for the ringing tone type.

At the receiving station, the ring tone type corresponding to the subscriber state at the time of receiving the call is registered in the conversion list in advance.

When subscriber 5OB-A is talking to subscriber 5UB-B and SUB-A has a call interruption service, if there is an incoming call from a third party 5UB-X,
In order to receive an interrupt call, the 5UB-AK incoming call display tone is output and a ring tone (RBT) is output to the SUX-X. At this time, the exchange processing system uses the conversion list (RBTCWT) shown in FIG. Ring tone type RBTatf corresponding to interrupt incoming state: pick up, its f
1 separate corresponding ring trunk RBTA 5UB-
Connect to call trunk 4 used by X.

By hearing the special ringing tone transmitted by the RBTA via the call trunk 4, the 5UB-X can know that an interrupt call is being made to the called subscriber 5LIB-A.

In addition, - in the case of being absent for some time, the subscriber can be registered on the absentee list as shown in Figure 2 using the well-known specific registration timetable. When a call is received to a subscriber.

In a manner similar to that described above, the calling subscriber can hear a ring tone corresponding to that type.

As described above, according to this embodiment, by providing the receiving station with different ring tones depending on the state of the called subscriber, the calling subscriber can know the state of the called subscriber. It also prevents discomfort and unnecessary dialing due to the non-response of the operator, thereby improving the exchange service.

〔Effect of the invention〕

As explained above, according to the present invention, one originating subscriber can know the status of the called subscriber by letting the calling subscriber hear different ring tones depending on the status of the called subscriber. In the case shown in the embodiment, even if the called subscriber does not respond for a long time, it is possible to know whether the called subscriber is at home or absent, and the exchange service can be improved.

In addition, even if the subscriber is temporarily absent, by specifying the status, the calling subscriber can reset the call after a few minutes, eliminating the need to take the trouble of using the absence registration service, and instead of making an announcement. This has the effect of providing a very economical service.
