Description

[Detailed Description of the Invention] [Summary] Regarding a data service control method in an exchange for accessing a database managed by an application processor when a call arrives at a data terminal housed in an ISDN-compatible exchange, the exchange The purpose of the present invention is to provide a service control method in an exchange that allows a processor to obtain information about the user of an originating terminal by controlling In the service control method, the exchange control unit issues a calling terminal information call request to request the application processor to call calling terminal information based on the calling terminal information and called terminal information in response to generation of a call from the calling terminal. The application processor includes a data management unit that is activated in response to a request from a calling terminal information call requesting unit, and a call control unit that controls switching connections. It is equipped with a called data terminal search unit that searches for called data terminal data, and a path connection request unit that is activated when data for called data terminal is searched and generates a request for connection between the called data terminal and the database. Data regarding the originating terminal in the database for the terminating terminal is configured to be supplied to the data terminal of the terminating terminal.

[Field of Industrial Application] The present invention relates to a data service control method in an ISDN-compatible exchange that accesses a database managed by an application processor when a call arrives to a user having a data terminal housed in an ISDN-compatible exchange.

In recent years, there has been a call for the transition to ISDN, and ISDN is being introduced in public telephone networks.
With the advent of DN services, it has become possible to connect two terminals to one line. In that case, two terminals, a voice terminal (telephone) and a data terminal, are often installed and used. Private branch exchanges (PBXs) compatible with ISDN have also been put into practical use, and various uses using data terminals are being attempted.

By connecting a computer to an ISDN compatible private branch exchange (PBX), it is possible to provide data processing services and database services to each data terminal. In other words, while the user of each data terminal is making a call using the voice terminal (telephone), the user accesses the computer connected to the exchange through a different path, extracts the necessary data from his own database at any time, and transfers it to the data terminal. It can be output. However, when using a data terminal in the business of responding to inquiries, the user of the data terminal must respond to a call from another voice terminal and access the database at that point when data regarding the calling terminal is needed. become. However, in this case, there are disadvantages such as the time it takes to obtain the necessary data, and improvements are desired.

[Prior Art] An explanatory diagram of a conventional example is shown in FIG. 40 in the diagram is a switchboard, 4
1 is an exchange control unit, 42 is an application processor,
43 is a database. Now, as shown in FIG. A path connecting the originating terminal A and the terminating terminal B is formed under the control of the exchange control unit 41,
Both the originating terminal number (telephone number) and the terminating terminal number are sent to the terminating terminal B via a control signal, supplied to and displayed on the voice terminal Bl, and the receptionist at the terminating terminal B responds with the voice terminal B1. A call is made.

In this state, the originating terminal A whose recipient terminal B is the user
If you need to retrieve data from your own (or group's) database and view it (for example, if calling terminal A is a customer and you need to view traditional transaction data about that customer during a call) , the acceptor at destination terminal B issues a request to access the database from data terminal B2. The exchange control unit 41 of the exchange 40 detects the request and inputs the request to the application processor 42. Then, the application processor 42 accesses the database 43 in response to the request, pulls out data regarding the user (originating terminal A) from the database provided corresponding to the terminal B, and sends the data to the application processor 42. ．． The data is sent to the data terminal B2 side of the destination terminal B via the exchange 40. The data terminal B2 receives and stores the data, displays it, prints it, etc., and provides it to the recipient.

[Problems to be Solved by the Invention] As described above, according to the conventional technology, the receptionist at the receiving terminal B receives a call from another user, such as an inquiry.
There are problems in that it is necessary to enter operations to access the database from a data terminal and wait for the user's data to be sent from the database, which takes time and effort, and it is not possible to obtain user information immediately. Ta.

SUMMARY OF THE INVENTION An object of the present invention is to provide a service control system in an exchange that allows a processor to obtain information regarding the user of a calling terminal under the control of the exchange when a call is received.

[Means to solve the problem] FIG. 1 shows a basic configuration diagram of the present invention.

1 represents a destination data terminal search unit, and 17 represents a database.

In the present invention, when an exchange control unit receives a connection request from a calling terminal, it accesses a database for subscribers of the called terminal via an application processor, retrieves data regarding the calling terminal user, and communicates between the application processor and the called data terminal. When a connection path within the exchange is established to connect the data, the data is sent to the destination data terminal.

[Effects] When the exchange detects a call originating from the originating terminal and receives the dialing information specifying the destination terminal, the ISDN exchange control unit 10 receives the originating terminal number A sent from the caller and the destination terminal. Number B is entered. Upon receipt of this information, the originating terminal information call requesting section 11 is activated and issues a call request for data regarding the originating terminal along with the originating terminal number A and the terminating terminal number B to the application processor 13.

In response to this, the data management section 14 of the application processor 13 drives the called data terminal search section 16 to search the database 17 and retrieve the database 171 provided corresponding to the called called terminal number B, thereby managing the data. Department 14.

The data management unit 14 thereby activates the path connection request unit 15, and the path connection request unit 15 requests the exchange control unit IO to connect the application processor 13 and the destination terminal data terminal (
sends a request to form a communication path to connect with the destination data terminal). When the exchange control section 10 receives this request, the call control section 12 connects the receiving terminal and the application processor by controlling the switching of the communication path of the exchange, and sends out data regarding the user of the originating terminal retrieved from the database. Note that while accessing the database, the exchange control unit 10 forms a connection path that connects the originating terminal (voice terminal) and the destination terminal (voice terminal side) by a voice path under the control of the call control unit 12. do.

20 in FIG. 2 is the originating terminal, which in this example represents the voice terminal, and 21 is the destination terminal, which includes the voice terminal 21a and the data terminal 21.
b are connected to the same line.

22 and 23 are devices constituting a PBX exchange according to ISDN, 22 is a switching device, 23 is a control device, 24 is a trunk which is an interface circuit with an application processor, 25 is an application processor (hereinafter simply referred to as a processor), and 26 is a file control device, 27
is a file device in which a database is stored.

The processor consists of various parts such as a CPU 251, a memory 255, and input/output interfaces 252 to 254, and is controlled by a program and can access the database of the file device 27 via the interface to perform processing such as searching and updating. .

The processing operation in the embodiment configuration shown in FIG. 2 will be explained using the processing flow diagram of the embodiment shown in FIG.

First, when the calling terminal 20 makes an outgoing connection requesting that the calling terminal 20 make a call and receive the call to the receiving terminal 21 (step 30), the control?
The fI device 23 detects the request from the exchange 22 and creates a communication path between the originating terminal 20 and the receiving terminal 21a using a voice path (step 36). On the other hand, the control device 23 sends an incoming call request signal including the originating terminal number and the terminating terminal number to the processor 25 via the signal line 231.

In the processor 25, there are 23 signal lines and 25 interfaces.
Upon receiving an incoming call request signal via 3 (step 31)
, based on the terminating terminal number information therein, it is determined whether the terminating terminal has a data terminal (step 32).

The identification is performed by referring to a table such as the example shown in FIG. 4 for identifying the presence/absence of a data terminal using the telephone number of the destination terminal. That is, in the case of telephone number "1222'," if "1" is output from the data presence/absence column, it can be seen that the terminal with that telephone number is equipped with a data terminal.In this identification, there is no data terminal. (When "0" is output from the table), the processing in the processor is terminated. In that case, the control device 23 is notified from the signal line 231 that the processing by the processor will not be performed.

If it is identified that the destination terminal has a data terminal, then a command is sent to the file control device 26 to open the database for the subscriber of the destination terminal (step 33). If there is no database for the calling terminal, the processing in the current server ends, and if there is, then it is determined whether there is data for the calling terminal in the database based on the calling terminal number that has already been received (step 34). As a result, if there is no data for the originating terminal, termination processing is performed, and if there is, then an incoming call request for the destination data terminal is sent from the signal line 231 to the control device 23 of the PBX exchange (step 35).

Upon receiving this incoming call request, the control device 23 performs control to form a path connecting the trunk 24 connected to the processor to the destination data terminal 21b (step 37), and sends a control signal to notify the destination data terminal 21b of the incoming call. send. When the path to the destination data terminal 21b is established, the processor 25
interface 252. sends the data about the originating terminal retrieved from the database to the interface 252. ) Rank 24. It is sent to the destination data terminal 21b via the exchange device 22. As a result, the user of the destination terminal can view the data of the originating terminal user on the display (display display or print display) of the data terminal 21b almost at the same time as responding to the call from the user of the originating terminal 20 using the voice terminal 21a. Can be done. Therefore, inquiries from the user of the originating terminal 20 can be answered immediately by looking at the displayed content.

[Effects of the Invention] According to the present invention, when a call is received, the user of the terminating terminal can know data related to the originating terminal from the display on the data terminal, so that various inquiries from the originating terminal can be smoothly responded to. For example, it is possible to improve services such as inquiries from other departments to the sales department within a company and inquiries between companies.
