Abstract

PURPOSE:To facilitate the retrieval of identification(ID) information or various services by forming a data base for controlling ID information or control information corresponding to each subscriber's number, and during the call connecting processing of an electronic exchange, accessing the data base device. CONSTITUTION:The data base device 17 stores ID information or control information corresponding to respective subscriber's numbers. When a call request is generated from a terminal connected to a subscriber line 11A, the call information is transferred to a call control part 13 through a subscriber storing part 12. After receiving the call request, the call control part 13 accesses the data base 17 to retrieve the subscriber information. Since the call control part 13 accesses the data base 17 at the time of call connection processing and retrieves display and control information relating to the subscriber number, the name display of the originating subscriber or various services such as transfer can be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic switching device that can connect and accommodate various terminal devices and has new functions such as subscriber identification information transfer.

2. Description of the Related Art Conventionally, this type of electronic switching equipment has a subscriber line function and a switching function. It is configured to allow communication between terminals.

FIG. 3 shows the configuration of a conventional electronic exchange.

In FIG. 3, the terminals are connected to a subscriber accommodation unit 32 via subscriber lines 31A to 31N. The communication control device is connected to trunk interface 35 via trunks 36A to 36N. The call control unit 33 performs switching processing and accesses the channel network 34 to set a channel path in response to call connection requests from the subscriber lines 31A to 31N and trunks 36A to 36N.

Next, the above conventional operation will be explained.

In FIG. 3, when a call request is generated from a terminal connected to subscriber line 31A, information is transferred to call control section 33 via subscriber accommodation section 32. In FIG. The call control unit 33 receives the outgoing request, selects the called party, checks the availability of subscribers and trunks, sends out the incoming call request, and accesses the channel network 34 to connect the incoming and outgoing lines. Set the call path.

In this manner, even the conventional electronic switching device described above can perform basic call connection processing and setting of communication paths.

Problems to be Solved by the Invention However, in the above-mentioned conventional electronic switching equipment, the station data managed for call connection control consists of subscriber numbers and
The problem is that various services such as searching for identification information corresponding to the subscriber number cannot be provided due to the blockage status and service class level, and various advanced services required for the subscriber number cannot be provided. There was a problem.

The present invention solves these conventional problems,
The purpose of this invention is to provide an excellent electronic switching device that can perform identification information searches and various services based on subscriber numbers.

Means for Solving the Problems In order to achieve the above object, the present invention provides a database device that manages identification information and control information corresponding to subscriber numbers, and allows the electronic switching device to access the database device during call connection processing. By doing so, identification information searches and various services are realized.

Effects The present invention has the following effects due to the above configuration. In other words, when the electronic switching device performs call connection control processing, it accesses the database device and uses the retrieved data to notify the other subscriber of caller identification information as additional call information, and to provide various services for the caller. , communication services such as automatic transfer based on subscriber numbers can be realized.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, the terminals are connected to a subscriber accommodation unit 12 via subscriber lines 11A to 11N.

The communication control device is connected to trunk interface 15 via trunks 16A to 16N.

Reference numeral 13 denotes a call control section, which performs switching processing and accesses the channel network 14 to set a channel path in response to call connection requests from the subscriber lines 11A to 11N and trunks 16A to 16N. 17 is a database device in which identification information and control information corresponding to subscriber numbers are registered. Reference numeral 18 denotes a console device, which performs registration, modification, and addition of information in the database device.

FIG. 2 shows an example of the structure of an information management table in a database device, and is composed of a subscriber number, a control code, and a provision information field (this information is called subscriber information).

Next, the operation of the above embodiment will be explained. In the above embodiment, when a call request is generated from a terminal connected to the subscriber line 11A, the request is sent to the call control unit 1 via the subscriber accommodation unit 12.
The call information is transferred to 3.

After receiving the call request, the call control unit 13 sends the database device 1
7 to search for subscriber information.

(Case A) If the retrieved information is an ID display, there is no particular effect on the call connection operation, and the content of the provided information field is notified to the other party's terminal as additional information of the call.

In this application example, the name of the caller is indicated by the caller number.

(Case B) If the retrieved information is a control command such as transfer or number change, the call control operation is continued by changing the other party's telephone number.

After accessing the database device 17, the call control unit 13 checks whether the other party's terminal is installed, empty, or blocked, and performs incoming call processing. Further, in response to a response from the called side, the call path network 14 is accessed and a call path is set.

According to the embodiment described above, the call control unit 13 accesses the database device 17 during call connection processing to search for display and control information regarding the corresponding subscriber number. It has the advantage of being able to realize various services such as

Effects of the Invention As is clear from the embodiments described above, the present invention accesses a database device during call connection processing to search for information corresponding to the subscriber numbers of the calling and called parties. It has the advantage of being able to provide notification of partner subscriber information and various exchange services corresponding to the subscriber number.
