Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching system, and more particularly to a system for monitoring the status of additional services provided by the switching system.

[0002]

2. Description of the Related Art Conventionally, a state monitoring system for supplementary services provided by a switching system is based on a call for basic call control or resource management or a supplementary service provided at a location where a change in the state of a resource needs to be detected. By embedding a state monitoring program corresponding to the above, a state change required for additional services was monitored.

[0003]

In the state monitoring method of the supplementary service provided by the conventional switching system described above, since the state monitoring is performed by the state monitoring program, the condition of the state to be added, deleted or monitored is added. However, when a change occurs, the state monitoring program needs to be rewritten, and the switching system needs to be temporarily stopped.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a supplementary service status monitoring method is provided for providing a supplementary service function.
In a switching system configured to define a state monitoring point that may detect a change in the state of a call or a resource in basic call control and resource management, and determine the operation of supplementary services depending on whether or not a state change is detected. State monitoring data, which is data for setting an additional service processing program to be started when a state change is required and a state to be monitored and a state change to be detected are provided for each of the state monitoring points, and from the additional service processing program, Means for setting and canceling status monitoring data; checking means for checking a status change by status monitoring data each time the status monitoring point is passed; and additional service processing program as a result of the status change check by the checking means. And a start-up means for starting.

[0005]

According to the present invention, the status monitoring data is set and released from the supplementary service processing program, and a status change is checked by the status monitoring data each time the status monitoring point is passed. As a result of the status change check, Start the supplementary service processing program.

[0006]

FIG. 1 is a block diagram showing an embodiment of the present invention. FIG. 1A shows an example of the configuration of a switching system, and FIG. 1B shows an example of the configuration of each unit included in FIG. This figure 1
In (a), 1 defines a state monitoring point that may detect a change in the state of a call or a resource in basic call control and resource management in order to provide a supplementary service function, and detects a state change. The switching system 1 is configured to determine the operation of the supplementary service according to the presence / absence of the resource management unit 2, the supplementary service status monitoring unit 3, the basic call control unit 4, and the supplementary service processing unit 5. In FIG. 1B, the resource management unit 2 includes a resource-specific management program 21. The additional service status monitoring unit 3 includes a status monitoring program 31, status monitoring data for each call 32, and status monitoring data for each resource 33. Also, the basic call control unit 4
Is constituted by a basic call control program 41,
The additional service processing unit 5 includes an additional service processing program 5
1, 52.

Here, the supplementary service status monitoring unit 3 cooperates with the status monitoring program 31 to set and release status monitoring data from the supplementary service processing program and to use the status monitoring data every time the status monitoring point is passed. A check means for checking the state change and a start means for starting the additional service processing program as a result of the state change check by the check means are configured.

FIGS. 2A and 2B are explanatory diagrams showing a configuration and a management method of the supplementary service state monitoring data used for explaining the operation of FIG. In FIG. 2A, 320
Is a per-call status monitoring data registration table, 321 is per-call status monitoring data, and the per-call status monitoring data 321 is linked to the call index α and indexed position of the per-call status monitoring data registration table 320. . The state monitoring data 331 for each resource shown in FIG. 2B is linked to a position indexed by the resource identification A in the state monitoring data registration table 330 for each resource. Also, the state monitoring data 321 for each call and the state monitoring data 331 for each resource
At the position indexed by the status monitoring point identification number 6, data (a value indicating the necessity of status monitoring) 7 indicating the necessity of status monitoring by “1” and “0”, and the status monitoring is required. In this case, a state 8 to be monitored and an additional service processing program unit number 9 to be started when a change in the state is detected are set. Reference numerals 511 and 512 indicate additional service A processing program units, and reference numerals 521 and 522 indicate additional service B processing program units.

FIGS. 3A and 3B are diagrams showing an example of the configuration of an additional service processing program used for explaining the operation of FIG. In FIG. 3, reference numerals 51 and 52 denote a processing program of the additional service A and a processing program of the additional service B. The processing program 51 of the additional service A is a program unit 511, 512, 513.・ ・ Consists of Also,
Similarly, the processing program 52 for the additional service B includes program units 521, 522, 523,...

Next, the operation of the embodiment shown in FIG. 1 will be described with reference to FIGS. First, when the additional service A needs to detect a state change such as the connection completion and the disconnection start of the call α during the execution, the data setting as shown in the state monitoring data 321 of the call α is performed. afterwards,
When the call α is completed and passes through a point having the state monitoring point identification number “2” in the basic call control, the basic call control program 4
The state monitoring program 31 called from step 1 detects a change in state based on the contents of the state monitoring data 321 of the call α, and activates the additional service A processing program unit 511. When the call α starts disconnection, the additional service A processing program unit 51
2 will be activated. Next, when it is necessary to detect the start and end of use of the resource A during the execution of the additional service B, the data setting as shown in the state monitoring data 331 of the resource A is performed. After that, when the resource A is started to use and passes the point having the status monitoring point identification number “1” in the resource management, the status monitoring program 31 called from the resource-specific management program 21 changes the content of the status monitoring data 331 of the resource A. , A change in state is detected based on the above, and the additional service B processing program unit 521 is started. Further, when the use of the resource A is completed, the additional service B processing program unit 522 is started in the same manner.

[0011]

As described above, the present invention is data in which the necessity of state monitoring, the state to be monitored, and the additional service processing program to be started when a state change is detected are set for each state monitoring point. Provide status monitoring data,
And a function of setting and canceling status monitoring data from the supplementary service processing program, a function of checking a status change by the status monitoring data every time a status monitoring point is passed,
By providing a function of starting the supplementary service processing program as a result of the state change check, there is an effect that it is not necessary to stop the switching system even when a condition for adding or deleting a supplementary service or monitoring a state occurs.
