JPS5925458A - Calling system - Google Patents

Abstract

PURPOSE:To reduce the connecting time, by using a calling system which is unconditionally decided in response to the identification number. CONSTITUTION:An exchange 1 receives the subscriber number of the remote side based on an originating request fed from an originating subscriber and then reads out a call signal table 2 contained in the exchange 1 with the received subscriber number of the remote side. The table 2 stores both communication terminal number and call number for each subscriber number. For instance, the audio signal showing the name of a subscriber in voices is coded and stored in the table 2 for a call signal. Then a synthetic voice signal corresponding to the subscriber of the remote side is produced based on the read-out call signal. At the same time, a communication terminal 3 read out simultaneously is caught by the corresponding number. Then the synthetic voice signal is transmitted to a subscriber line 4 to call out the subscriber name. It is also possible to call a number by a visual system in addition to an audible signal.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a calling method (2) when one communication terminal is commonly used by a plurality of subscribers, and in particular (2) attempts to make a calling method that distinguishes between subscribers. It is something.

<Background> Conventionally, subscriber terminals have been assigned a unique identification number (5tation identification number).
8 ID), and exactly the same calling system has been used for terminals of the same type even if their subscriber numbers are different. For example, if we take general home telephones as a typical terminal, all telephones receive a ringing signal (a 400Hz signal of 32H1?) from the exchange side.
A variable signal) is sent intermittently, ON for 1 second and OFF for 2 seconds.

Since subscriber terminals of the same type use the same paging method, multiple parties using the subscriber terminal C
For the second time, it was unclear who was actually being called without talking to the caller. So when a call occurs, someone picks up the handset, talks to the caller, listens to who is to be on the other end, and then switches places with that person. It was getting complicated.

In addition, a subscriber number that uniquely identifies subscriber C2 is assigned, not to the subscriber terminal, and that subscriber uses his/her subscriber number (Person Identify, P I
I)) can be registered or canceled on a communication terminal, allowing many subscribers to share the same communication terminal, receive call forwarding and other functional services, and communicate with the subscriber wherever they are. Communication methods that can be used (for example, Japanese Patent Application 1987-
No. 47583) has been proposed.

When subscribers with different PIDs share the same C-terminal in this way, the current paging method using the same paging method cannot specify and call a subscriber with a specific PID.

<Summary of the Invention> In order to solve these drawbacks, the present invention facilitates the calling of a subscriber (pair of subscribers) each having a unique identification number by using a specified calling method. According to the invention, when a call is made to the other party's subscriber number in response to a call request, the calling signal table is referred to using the other party's subscriber number, and the communication terminal number and the calling signal in which the other party's subscriber number is registered are read out. Communication terminal C that followed one after another:
The communication terminal sends out the paging signal to the other subscriber (2) using the paging signal C- to make a predetermined unique audible or visual paging.

<Example> FIG. 1 shows an example of the invention. When the exchange 1 receives the calling subscriber's number from the originating subscriber, it reads out the calling signal table 2 stored in the exchange 1 with the received subscriber number. The call signal table 2
(- is stored for each subscriber number, oral communication terminal number and call signal.

In this example, the name of the subscriber is encoded and stored as a voice signal generated by voice as a calling signal.
Based on this read out call signal (two-speech synthesis technology (-
A synthesized voice signal corresponding to the name of the other subscriber is created, and the communication terminal read out at the same time is captured from the communication terminal number C: and the communication terminal 3 is captured from that subscriber line 46 and the synthesized voice signal No. 18 is sent to the communication terminal. The subscriber's name is called out using a synthesized voice from the loudspeaker No. 3. This call may be made in the same manner as the call using the so-called expanded P-talk method. In this way, the subscriber can be called directly.

This method of calling a subscriber by uttering the subscriber's name using synthesized voice C- is considered to be the best method in that it can uniquely identify and call the subscriber. If a subscriber is registered, the subscriber is often called using a synthesized voice (secondarily, this may give an unpleasant impression as intelligible noise to people in the vicinity of the communication terminal).

To solve this problem (the second is the traditional constant frequency,
Instead of ringing at regular intermittent intervals, for example, the ringing tones are repeated at time intervals T1. T,,T,...Tn and signal S1. Using the frequencies of S, , S, . Signal table (- This is stored in correspondence with the subscriber number, and is read out and input into the terminal 3 to identify and call the subscriber.In this way, a combination of audible signals that directly calls the subscriber's name. The paging signal by C2 depends on the subscriber's degree of identification, so it is inferior to the synthetic voice method, but since the paging method is always the same for the subscriber, after getting used to it to a certain extent, it is difficult to hear the call signal in the fake sound (even if it is C2). This makes it possible to identify the ringing tone of the subscriber.Furthermore, this ringing method is unintelligible noise, and has the advantage that it has a small effect on surrounding people as noise. ing.

Conventional 1: Even in the case of call forwarding, calls are sent to subscriber terminal A.
If a call to subscriber terminal B is registered for call transfer, the call to subscriber terminal A is first made with a short cycle ring tone, and then a normal ring tone is sent to subscriber terminal B. Therefore, it is relatively easy to change the ring tone. Furthermore, T1. T, ,
For each ON time of T11 etc. 1: Using multiple frequencies, each O
A configuration in which a plurality of frequencies are used also at N time can be considered as an application example. Of course, it is also possible to change the frequency from f to f within each ON time.

In addition to the caller's frequency and intermittent interval already mentioned as parameters of the paging signal, the terminal is equipped with several lamps of the same color or different colors, and the blinking interval of the lamps and the combination of colors are changed depending on the subscriber identification number. It is also possible to specify and call a subscriber or subscriber terminal by using it in conjunction with the above-mentioned ring tone.

In this case, the calling signal may be separated and identified by a p-wave device at the terminal, and the corresponding lamp may be lit. Furthermore, as another application, it is possible to add a character display device to a terminal (2) and combine only characters with a lamp or characters and a ringing tone (2), thereby making it possible to identify and call a subscriber or terminal. In this case, the calling signal may be separated using a P-wave device or the like and the corresponding display may be driven.

FIG. 3 shows an example of the construction of a pond according to the present invention.

In the embodiment of FIG. 1, a call signal generator is provided on the exchange side, and in FIG. Based on that information, a paging signal generator 2 installed on each terminal generates a specific paging signal corresponding to the subscriber (2) and calls the phone. (-It is also possible to share the used multi-frequency generator etc. as a ring tone within the same terminal.

As explained above, this invention (- According to C2, using a calling method uniquely determined according to the identification number (=)
It becomes possible to call a specific subscriber, and to avoid calling the wrong subscriber, the connection time can be shortened, and the service life can be improved. .
