Abstract

PURPOSE:To recognize the telephone number of a caller when a subscriber is called during absence, by dialing a specific number of the incoming subscriber. CONSTITUTION:When a subscriber S2 registrates the request if incoming number message service to an exchange station B, if there is an incoming call from a subscriber S1 during the absence of the S2, the exchange station B writes a telephone number of the S1 transmitted from a common line signal transmitter/ receiver CSC in an area assigned to the S2 of a storage device MM. The S2 knows the telephone number of the S1 in voice by means of a voice message editor AMSGE and a voice output trunk AMSGT. Through the similar means, the telephone number of the caller is printed on a printer equipped with a telephone set by means of a data editor DMSGE and a data output trunk DMSGT.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a called number message service system in a telephone switching system.

Conventionally, this type of called number message service has been known as an answering machine, etc., and the called party presses a button in advance at the called party's telephone terminal or switchboard to indicate that the call is not available.

Alternatively, by dialing a special predetermined telephone number, the voice of the calling subscriber can be transmitted via a communication path established between the calling subscriber and the calling subscriber directly onto magnetic tape or a magnetic drum, or Editing information for predetermined audio pieces is stored, and the receiving subscriber can later retrieve this stored information as audio information.

However, according to such services, after the calling subscriber receives the information that the caller is on the answering machine on an audio tape, etc.9, for example, a short message such as ``please call me'' is sent to the aforementioned magnetic tape, etc. It is fully expected that formal messages will often be recorded.

In addition, the receiving subscriber has to play back all of these memorized messages, and considering the fact that the playback time is required depending on the traffic, and the mental aspect of interacting with the magnetic tape, It could not be said that the service fully met the requirements expected of an answering machine.

An object of the present invention is to eliminate the above-mentioned conventional problems.

1 without requiring the subscriber to go through any complicated operating procedures.
To provide a called number message service system in a telephone exchange system, in which the called subscriber can extract the telephone number of the calling subscriber who has received the call by dialing a predetermined special telephone number.

Next, an embodiment of the called number message service system according to the present invention will be described with reference to FIG. 1.

FIG. 1 is a block diagram showing a relay system according to an embodiment of the present invention. In this example.

When the originating subscriber SL takes off-hook the telephone to call the terminating subscriber S2, the exchange controller C0NT of the switching center A controls the exchange switch SW to capture the empty outgoing call register ORT and performs one outgoing call using a known method. The transmitter S, and the outgoing register ORT are connected. A known DT tone is then transmitted to the calling subscriber S1 to prompt the calling subscriber S2 to dial the telephone number. Outgoing subscriber S! When dialing the terminating subscriber S2, it selects and captures the outgoing trunk OCT with the call line to the exchange B that accommodates the terminating subscriber S2 by a known method, and dials the corresponding incoming trunk I of the exchange B.
Start CT. At the same time, the telephone number of the called subscriber S2 dialed by the above-mentioned calling subscriber Sl and the telephone number of the calling subscriber Sl are extracted in the common line signal transmitting/receiving device CSC via the common line C using a known method. and send it together.

On the other hand, at exchange B, the received subscriber S2 and the paging trunk RGT are connected by a known method using the received called telephone number. At this time, at the same time, the exchange control device C0NT determines that the second called subscriber S2 is the subscriber who requested the first called number message service based on the content read from the storage device MM.
If it is determined, the telephone number information of the calling subscriber S is stored in the storage area in the storage device MM allocated to one receiving subscriber S2. Note that if one called subscriber S2 has not requested the called number message service, the above-mentioned telephone number information of the calling subscriber Sl is discarded so as not to increase the storage capacity of the storage device MM.

Here, since 9 incoming subscriber S2 is away, 9 outgoing subscriber S
, abandons the call to the called subscriber S2,
The explanation continues below. As already mentioned, the telephone number information of one originating subscriber S1 is stored in the area of the storage device MM allocated to the incoming subscriber S2. , it is possible to sequentially store telephone number information of new calling subscribers without destroying the stored contents. Additionally, outgoing trunk OCT and incoming trunk ICT via telephone lines have been restored.

Restoration of connection via SW such as paging trunk RGT and the like is a well-known technique and will not be described here. In this way, to explain how subscriber S2 retrieves the stored contents of the storage device, service requesting subscriber S2 takes the telephone off-hook in order to know the telephone number information of the calling subscriber who received 7 calls. Then, the communication is performed with the transmission register ORT of the local station using a known method. The subscriber S2 then dials a predetermined special telephone number. Here, when the above-mentioned storage contents are to be retrieved in the form of voice, the voice output rank AMSGT and the subscriber S2 are connected by a known method based on the contents of the special telephone number. In addition, if the phone is equipped with a terminal that allows printing, and

When exporting the above-mentioned memory contents by printout, the data output rank DM
The SGT and subscriber S2 are connected in a known manner. Also, the above audio output rank AMSGT.

Alternatively, the digital output rank DMSGT is the audio editing device AMSGE or the data editing device DM, respectively.
Sequentially from the corresponding storage area of the storage device MM connected to the SGE and via the exchange control device C0NT.

Audio to subscribers 2. Alternatively, the data is extracted and the stored area is erased according to predetermined conditions. As a result, the corresponding area is again put on standby so that it can be used when the subscriber is away.Next, a case will be explained in which the service requesting subscriber S2 is called and the subscriber S2 answers the call by hooking off the telephone. In this case, it basically depends on the choice whether or not to delete the calling subscriber's telephone number information for answered calls, but if it is deleted, it will be remembered only when you are away, that is, only for calls that were not answered. Since the messages are left one by one, it becomes a simplified version of an answering machine service. According to this, by dialing special telephone number information before receiving the first call, the telephone number information of the calling subscriber who answered is transmitted to the incoming call by voice or data output means as described above. In addition to being able to provide a caller telephone number inquiry service, it can also be used as a malicious call detection method. Further, if the telephone number information of the calling subscriber that has led to the response is not deleted, there are many advantages such as the ability to realize a single call detail service.

As is clear from the above description, according to the present invention, the calling subscriber simply dials a predetermined special telephone number without the calling subscriber having to go through any troublesome operating procedures. Because you can know the phone number of the calling subscriber who received the call.

Improving the efficiency of operations 1 Inquiry about the calling phone number that led to the incoming call, detection of malicious calls 1 Incoming call details service, etc. have great effects in improving the message service.
