DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange for implementing an additional service, and more particularly to an execution state management system for a connection control additional service.

[0002]

2. Description of the Related Art Conventionally, this type of additional service execution state has been managed independently in a service execution program for each additional service.

[0003]

In the conventional state management system described above, when a plurality of services are simultaneously executed, or when a service is interrupted during service startup, another service is started, and the service returns to the original service after the service ends. In addition, a plurality of service execution programs are complicatedly related to each other, which complicates maintenance work. In other words, there is a drawback that the addition of a new service and the deletion / modification of an existing service are not limited to the change of the service, but have a great effect on other services.

An object of the present invention is to provide a connection control system additional service execution state management method which solves the above-mentioned problems.

[0005]

In order to achieve the above object, in a connection control system additional service execution state management system according to the present invention, in realizing a connection control system additional service provided by an exchange, calls are separated by ingress and egress. The basic call control unit for realizing the processing allocates and controls a plurality of calls, and establishes the logical connection relationship between the call and the call and the service from the call to the service activated on the call and the plurality of calls. from the service activation in service at the time of simultaneous execution of the following services, and from service when returning to interrupt service in the middle service start to <br/> original service after completion of start another service service a link to the service being suspended managed by tree format, the service own status and service control for each supplementary service for each supplementary service The function of storing necessary service data is managed independently of the service execution program and the supplementary service analysis program for each supplementary service, and the execution state of the connection control supplementary service is managed, and the service is provided to the supplementary service execution program and the supplementary service analysis program. Provides a common interface for execution management status management
Is what you do.

[0006]

The present invention facilitates the addition of a new service and the change of an existing service by reducing the relationship between services that can be executed simultaneously.

[0007]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.

In the figure, 1 is a basic call 1 between subscribers A and B, 2 is a basic call between subscribers A and C 2, and 3 is a basic call n between subscribers A and X. 4, a call control task for controlling the subscriber A side of the basic call 1, 5 a call control task for controlling the subscriber A side of the basic call 2, and 6 a subscriber A for the basic call n
7 is a call control task for controlling subscriber B of basic call 1, 8 is a call control task for controlling subscriber C of basic call 2, and 9 is a subscriber of basic call n. This is a call control task for controlling the X side.

10 is an additional service analysis program,
11 is an additional service execution program, 12 is a basic call / additional service execution unit, and 13 is an additional service execution state management unit.

Reference numeral 14 denotes an additional service execution state management unit common interface, 15 denotes an additional service execution state management table corresponding to a basic call, 16 denotes an additional service execution state management table corresponding to a service, and 17 denotes service data.

In this embodiment, a basic call control unit that implements call processing by separating incoming and outgoing calls has a format in which a plurality of calls are allocated and controlled. From the service started on the call, from the starting service to the next service when multiple services are executed simultaneously, or from the service to the suspended service when interrupting one service and starting another service Are managed by the supplementary service execution state management tables 15 and 16, and a function of storing a service-specific state for each service and service data 17 necessary for service control for each service is provided by the basic call / additional service execution unit 12. Independently, the additional service execution state management unit 13 manages the execution state of the connection control additional service.

That is, when a service start event is received by the basic call control task A1 for controlling a basic call corresponding to the service invoker A, the supplementary service analysis program 1
Start 0. The supplementary service analysis program 10 performs contention analysis by inquiring the supplementary service execution state management unit 13 about the service currently activated by the subscriber, and determines whether the supplementary service can be activated.

The supplementary service execution state management unit 13 is shown in FIG.
The additional service execution status management table 15, as shown in FIG.
16 and stores the running service. When the service can be started, the service execution program 11 for realizing the connection control additional service is started. The service execution program 11 sends, to the additional service execution state management unit 13, a hunt request for the additional service execution state management table 16 corresponding to the service and a linkage connection request with the additional service execution state management table 15 for the basic call.

The supplementary service execution state management unit 13 makes a linkage connection between the call and the newly activated service if it is the first service for the subscriber, and newly activates from the activated service if there is an activated service. Automatically connect the linkage to the service.

The service execution program 12 provides a second call controlled by the basic call control task A2, for example, for a three-party call service (a call between subscribers A to C) , to a newly originated call. In the case of a call waiting service, a linkage connection is made between the supplementary service execution state management table 15 corresponding to the incoming call and the supplementary service execution state management table 16 corresponding to the supplementary service.

FIG. 3 shows a call waiting during a three-party call as an example of an execution state management table for simultaneous execution of a plurality of services in which three or more calls are related. Even when a call waiting call is received during a three-party call and the fact is sent to all the related subscribers in an out-of-band message, the related call is read from the supplementary service execution state management unit 13 at that time. This allows transmission.
Data required for service control such as a trunk number for three-party communication when implementing the three-party communication service is stored as service data of the additional service execution state management unit 13. The additional service execution state management unit 13 stores the service data in a form that secures an area of the requested size without sensing the contents of the service data.

Even when one service ends when a plurality of services are started, the additional service execution state management unit 13 automatically changes the linkage in response to a release request of the service corresponding execution state management table 16 from the service execution program 11.

Also, when a service is interrupted halfway and another service is executed to return to the original service, a service interruption / return program should be prepared in advance on the old service side and saved at that time. This processing can be realized by storing necessary data as service data in the additional service execution state management unit 13 and creating the processing using a common interface that can be called from an arbitrary service. Here, the old sir
A service is a service that was started first, and a new service

[0019]

As described above, according to the present invention, when a plurality of services coexist and are simultaneously executed, the individual calls are only conscious of the logical connection relationship between the calls and the calls and the services at that point in time. The service can be controlled independently, and when interrupting the service in the middle and executing another service and returning to the original service, prepare a program for interrupting and returning the old service in advance and provide a common interface and provide a common interface In this case, the program can be easily realized by calling the program, the effect on other services can be minimized, and a third party can develop a new service.
