Provide a state notification destination management table, detect the call state set in this table, notify the information processing system, and share the functions of the two to provide advanced services without deteriorating the performance of the switching process. An interface is arranged between a communication system to which terminals are connected and an information processing system for providing services, and a call state notification destination for setting a call state notification condition and a notification destination in association with a call number in the interface. A management table is provided, in response to the information processing system notifying the interface of the call state notification condition and the notification destination. The interface receives the call number assigned to the call from the communication system, sets the call status notification condition and the notification destination in the call status notification destination management table in association with the call number, and sets the call status from the communication system. The interface is configured to notify the notification destination of the corresponding information processing system set by referring to the call state notification destination management table based on the notification of the transition.

[Industrial applications]

The present invention relates to a call state transition notification method for notifying a call state transition of a terminal connected to a communication system to an information processing system. With the recent sophistication of communication systems,
The provision of more advanced services is required. The provision of a simple procedure service (such as call forwarding) can be added to the software of a conventional communication system. However, a service including a complicated procedure (telemarketing service: a service for identifying a caller, searching for detailed information of the caller and a destination, and displaying the searched caller information on a data terminal of the destination) was considered. In this case, if the service is controlled only by the conventional communication system, the processing efficiency of the connection control in the communication system is reduced. For this reason, provision of a service by cooperation between the communication system and the information processing system can be considered. At this time, in the information processing system, in order to control the service of the communication system, the state of the call (the state of the communication path between the communication terminals) to be service-controlled always transitions to any state (for example, the user is suspended from the connection state). It is required to know in real time whether or not the user has pressed the button and transited to the pending state.

[Conventional technology]

The service of the conventional communication system has been provided in cooperation with an exchange processing program in the communication system and an application program. However, as services become more sophisticated, application programs become more complex, and more execution time is required, thereby reducing the processing efficiency of the exchange process. Further, the required communication service is different for each user who purchases the communication system (for each business such as a hotel, a business office, and a department store), and the development of the communication service is performed by one skilled person.

[Problems to be solved by the invention]

Therefore, when developing an application program for the communication system, it is necessary to consider the influence on the exchange processing, and there has been a problem that it is difficult to provide a complicated service or a service for searching a large amount of data. Therefore, it is desired to notify the information processing system of the transition of the call state in the communication system in real time.

The present invention provides a call state notification destination management table in an interface arranged between a communication system and an information processing system, detects a call state set in the table, notifies the information processing system of the call state, and shares the functions of the two. The purpose of the present invention is to realize the provision of advanced services without deteriorating the performance of the exchange processing.

〔Example〕

Next, the configuration and operation of one embodiment of the present invention will be sequentially described in detail with reference to FIGS.

In FIG. 1, a terminal 1 is a terminal to be serviced. The terminal 1 is given a telephone number such as "2-1111".

The communication system 2 is a system that performs a switching process or the like by connecting a plurality of terminals 1, and includes terminal status detection units 2-1 to 2-n that detect the status of the terminal 1 (incoming call, hold, disconnection, etc.), and It is composed of an exchange processing unit 3 for performing an exchange process.

The interface (TCSI) 4 according to the present invention is disposed between the communication system 2 and the information processing system 5, and notifies the information processing system 5 of a call state transition of the terminal 1 ( (See FIG. 3). Call state notification destination management table 4-1 provided inside interface 4
Sets a condition (call state notification condition) to notify the information processing system 5 in association with a call number between terminals 1 connected to the communication system 2 (a number assigned to a communication path between the terminals 1) and a notification destination. It is a table to do. The call state notification condition, for example, “notification at call termination” is a condition for notifying a preset notification destination (service control ID) when a call is terminated due to disconnection of a path in a two-party connection (No. 2). The TCSI message generator 4-2 generates and transmits various messages to the service controllers 5-1 to 5-n. TCSI stands for Telecommunications & Computer Services Interface.

The information processing system 5 includes service control units 5-1 to 5-n and performs various services (for example, services such as measurement of call time).

FIG. 2 shows an example of a call state notification destination management table according to the present invention.

In FIG. 2, a call status notification destination management table 4-1 is shown.
Is the service control ID associated with the call number (notification destination)
And a table for setting a call state notification condition. The table number is a number assigned to each entry of the call state notification destination management table 4-1 and is used to point from the processing sequence management table 4-3. Here, the call number is a unique number assigned by the communication system 2 to the communication path between the terminals 1. The service control ID of the notification destination is one of the service control units 5-1 to 5-n included in the information processing system 5. The call state notification condition is a condition for notifying the service control unit ID.

The processing sequence management table 4-3 stores, in a register associated with a program number, an address pointing to a corresponding table number of the call state notification destination management table 4-1. When the address is stored here, the call number is registered in the notification destination (service control ID) stored in the call status notification destination management table 4-1. On the other hand, when "no notification" is stored, the registration is not performed. .

Next, the operation of the configuration of FIG. 1 will be sequentially described in detail with reference to FIG.

In FIG. 3, a request is made to notify a call termination notification or the like through a two-party connection. This is a message in which the AP (service control unit) constituting the information processing system 5 requests the interface 4 for a two-party connection, and further requests a notification of a call disappearance in the two-party connection.

Set in the table. In response to this notification, for example, as shown in FIG. 2, the service control ID “1” and the “call termination notification” are set in the call state notification destination management table 4-1 (call number is We will set it later).

 Informs the PBX (exchange) of the two-party connection.

 Makes a call to two of the terminals 1 notified of the PBX.

 Performs line connection.

Informs the call number. After the two parties are connected, the PBX notifies the interface 4 of the call number uniquely assigned to the connected communication path.

Sets the notified call number in the table. This sets the notified call number as, for example, the call number "1000" in FIG.

 Notifies the service control unit of the notification destination of the call number.

Makes a call between the terminals 1 that have been called and connected to each other.

 Cuts the path.

 Releases the line.

In response to the release of the line, a call number is added to the call disappearance notification, and the call is notified to the interface 4.

Searches the table. This is done by searching for, for example, the entry shown in FIG.

Sends a call termination notification. This is the service control ID that is the notification destination of the entry found in, for example, FIG.
At “1”, a call termination notification is issued. At this time, in the case of a call cancellation notification, the corresponding entry of the call status notification destination management table 4-1 is released.

Through the above processing, the AP notifies the interface 4 of the call termination notification by, for example, a two-party connection, and the interface 4 sets this in the internal call state notification destination management table 4-1. The call number of the notified two-party connection is set, and the call state notification destination management table 4-1 is searched in response to the call deletion notification from the PBX, and the call destination notification AP is notified of the call deletion notification. The AP can know the transition of the call state in real time. In response to the real-time notification of the transition of the call state, the AP can easily provide various services (for example, a service of a talk time) without lowering the line connection efficiency.

FIG. 4 shows an example of a setting procedure for a call state notification destination management table according to the present invention.

In FIG. 4 (a), the interface (TCS)
I) 4 waits for reception of a call control message from the information processing system 5. This is because interface (TCSI) 4
FIG. 1 waits for a call control message (for example, a two-party connection) from the service control units 5-1 to 5-n.

Determines whether notification is required. This is done by waiting for the reception of the call control message, and determining whether or not a "call termination notification" in the received call control message requiring notification, for example, in the two-party connection in FIG. 3, has been notified. YES
In the case of, the following processing is executed. If NO,
Execute

Has determined that notification is required, obtains an empty table, and sets the notification destination and conditions. This acquires an empty entry in the call state notification destination management table 4-1 in FIG. 2, sets a notification destination in the field of the service control ID, and sets a condition in the field of the call state notification condition.

Sets the use table position in a register in the processing sequence management table. This sets the used table position (address of the table number) in a register in the processing sequence management table 4-3 in FIG. And
Execute

Further, since it is determined that notification is not required, "not notified" is written in a register in the processing sequence management table (see the contents of the register in the processing sequence management table 4-3 in FIG. 2). Then, execute

Transmits the call control parameters and the program number to the exchange processing unit. This transmits a call control parameter (for example, two-party connection) and a program number (for example, program number "1") to the exchange processing unit as shown in FIG.

In FIG. 4 (b), the interface (TCS)
I) 4 waits for a call control response from the switching unit.

Checks whether the table number is set in the register from the program number in the parameter. This is because, for example, the program number in the parameter notified from the exchange processing unit to the interface 4 is set, for example, the second
The table position (call status notification destination management table 4-1) is stored in the corresponding register in the diagram processing sequence management table 4-3.
Check if the address that points to the address is set.

Determines whether there is a setting. If YES,
Execute If NO, execute.

Sets the call number of the call established in the call number field of the call state notification destination management table by extracting it from the parameters. This is shown in FIG.
For example, the call number “1000” is set in the call number field of No. 1.

 Sends the response result to the service control unit.

By the above processing of FIGS. 4 (a) and 4 (b), the call number, the call number,
A service control ID (notification destination) and a call state notification condition are set.

FIG. 5 shows an example of a procedure for transmitting call state notification information according to the present invention.

In FIG. 5, the interface (TCSI) 4 waits for reception of the call state notification information from the switching processing unit 3.

Searches for a notification destination from the call number. This is because the call number (unique number assigned to the communication path between the terminals 1) notified from the exchange processing unit 3 is searched and found in the call state notification destination management table 4-1 in FIG. Find the notification destination (service control ID) corresponding to the number.

Determines whether the call state is call cancellation. In the case of YES, the corresponding entry data in the call state notification destination management table 4-1 is released and executed. If NO,
Execute

 Transmits the call state information to the service control unit.

According to the above processing, the interface (TCSI) 4 having received the notification of the call number from the switching processing unit 3 releases the corresponding entry when the call state disappears, and thereafter receives the notified call state information (for example, call disappearance, etc.). ) Is notified to the service control unit of the notification destination.

In the above embodiment, the call destination is notified to the notification destination (service control ID) when the interface 4 matches the call state notification condition. You may make it search and notify only a notification destination.

〔The invention's effect〕
