Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a communication service, and more specifically to a communication service in which an electronic exchange such as a private branch exchange (PBX) and a computer are interlocked with each other. The present invention relates to a terminal state management method on the computer side when the computer side is notified by.

The term "terminal" used in this specification includes all the following contents. 1. Extension telephones under the PBX, relay stations, data terminals 1. A trunk for connecting the PBX to the public network or another PBX. Telephones, relay stations, data terminals connected to public networks and other PBXs that can communicate with terminals under the PBX.

[0003]

2. Description of the Related Art In a PBX-computer linked service, when a PBX notifies a computer of call and terminal states in a call-corresponding manner, one notification (such a call-corresponding state change notification sent from the PBX to a computer as a call) is used. The term "call event" in the specification) includes information related to one call, and thus one call event includes information about a plurality of terminals.

On the other hand, when a computer provides a service, many services do not need to manage the states of all terminals under the control of the PBX. Also, PBX
In order to manage the states of all the terminals under its control, enormous computer processing capability and high-speed communication capability between the PBX and the computer are required, which is expensive and impractical. For this reason, the computer side causes the PBX to send a call event related to the terminal that needs to know the state in order to provide the service, but actually the computer side knows the state during the call event. It also contains information about terminals that may not be needed.

Therefore, conventionally, since such a call event is processed, in the state transition mechanism on the computer side, it is determined whether or not the terminal in the call event at the time of state transition is a terminal requiring state management, which is suitable. The method of transitioning to the state was adopted.

Specifically, as shown in FIG. 3, for example, P
When the extension A disconnects in the meeting call state in which the extension A under the control of the BX holds the terminal B and talks with the terminal C, the call transfer (call transfer) service of the PBX is activated. At this time, terminals B and C can talk, but the PBX tells the computer that "terminal A is terminal B."
Has been transferred to the terminal C ”.

Upon receiving this call event, the computer side determines whether or not the terminals A, B and C are subject to state management, and if only the terminal A is subject to state management, the terminal A is set to an empty state. If the terminal A is the status management target and the terminal B or C is the status management target, the terminal A is set to the idle state and the terminals B and C are set to the communication state. Further, if the terminal A is not subject to state management and the terminal B or C is subject to state management, the terminals B and C are put into a call state.

[0008]

However, in such a conventional technique, after receiving a call event, all determination processes are individually performed as shown in FIG. Therefore, there is a problem that the state transition mechanism in the computer becomes complicated.

The present invention eliminates the problem of the prior art that the state transition mechanism in a computer becomes complicated, and facilitates application development on a computer. The computer side of an electronic exchange-computer linked service. The purpose of the present invention is to provide a terminal status management method in the above.

[0010]

In order to solve the above problems, the present invention provides a terminal state management system on the computer side in a communication service in which an electronic exchange is linked with a computer, when a call event is received from the electronic exchange. Performs event reception processing related to the call that is the target of the event, and after the event reception processing, performs call state transition processing without being aware of whether the terminal related to the call is a terminal that needs to be managed by the computer. State management non-target call removal processing that checks whether the call status resulting from the transition processing includes a terminal that is a management target of the computer, and removes this call status in the case of an unmanaged terminal that is not a management target By performing the state transition process and the state management non-target call removal process in sequence, the state transition process for terminals and calls in the computer is performed. It is carried out.

[0011]

According to the present invention, the state transition mechanism on the computer side performs state transition processing for performing only state transition without considering whether the terminal relating to the call is subject to computer state management, and the resulting call state. It is divided into two steps of state management non-target call removal processing, which checks whether or not a terminal that is subject to computer status management is included and removes the status of a call that does not include a terminal that is subject to computer status management. This simplifies the state transition mechanism on the computer side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a terminal status management system on the computer side of an electronic exchange-computer linked service according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows processing blocks of an embodiment when the present invention is applied to a terminal state management system on the computer side of a PBX-computer linked service. 2 is an example of a system configuration to which the terminal state management system of FIG. 1 is applied. The present invention is not particularly limited to the system configuration example shown in FIG.
Other PBX and other networks are connected to X1,
It houses multiple extensions and data terminals. The data terminal 5 may be connected to the PBX 1 and the computer 3 by separate lines, or may be connected to a common data line.

Returning to FIG. 1, the computer 3 is connected to the PBX which performs call processing of the accommodated terminal by the data line 100, and receives the terminal and call state change notification from the PBX via this line 100. The computer 3 is also connected to the data terminal 5, for example, via the data line 102, and the status is displayed on the display of the data terminal 5 associated therewith in response to the service processing.

When the computer 3 receives a call event from the PBX 1, the computer 3 executes an event reception process. That is, the event is accepted, the event is normalized for internal processing, and the call management memory block for the call that is the target of the call event is extracted. Then, after performing this event reception process, the state transition mechanism 30 of the computer 3 is activated.

FIG. 4 shows an operation at the time of call transfer service as an example of the processing operation of the state transition mechanism 30 shown in FIG. In this processing example, the case where the state transition mechanism 30 is activated by a call event "terminal A has transferred a call with terminal B to terminal C" is shown. In the state transition mechanism 30, a state transition process for performing only state transition without being aware of whether the terminal related to the call is subject to computer state management, and a call state resulting from the state transition process is a terminal subject to computer state management. And whether or not the state management target terminal of the computer is removed and the state of the call that does not include the state management target terminal of the computer is removed. The state transition processing temporary memory, the call management memory block, and the terminal management memory shown in FIG. 4 are formed in the state management processing memory 32.

State transition processing is shown in the following -1 to -3: -1: The call management block shown in the temporary memory for state transition is changed to two call management blocks which are the result of the state transition. Here, "state: empty" and "terminal: A" are set in one call management block (300), and another
In one call management block are “Status: Busy” and “Terminal:
B, C "are set (302). -2: The part corresponding to the terminals A, B, C in the terminal management memory is changed to point to the call management block including each terminal. : The state transition temporary memory is modified to point to both call management blocks that result in a state transition.

Next, the state management non-target call removal processing is shown in the following -1 and -2. In the processing example of FIG. 4, the terminals B and C are assumed to be state management non-target terminals, and the state of the terminal A is left as a finally necessary terminal. -1: It is determined whether or not the terminals in the call management block indicated by the state transition temporary memory are status management target terminals, and if all terminals in one call management block are not status management target, call management block And the areas used by those terminals in the terminal management memory are released. -2: -1 is performed for all call management blocks indicated by the temporary memory for state transition.

After the above-mentioned state transition mechanism 30 is finished, the actual service processing is performed according to the change of the state, for example, the call in the queue is received by an empty terminal, the display or lamp of the data terminal 5 is controlled, etc. Is done.

In the present embodiment, the PBX-computer interlocking is explained, but the present invention is not limited to the PBX in particular, and a general telephone exchange, a data exchange and a computer are interlocked with each other, and the computer is operated on a call-by-call basis. It can also be applied to the terminal state management process on the computer side when a service is to be provided using the notified call event.
