Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for automatic normality check processing of calls in an electronic exchange. In particular, it is used for automatic normality check processing of a call controlled by an additional processor in an intelligent network which is composed of an electronic exchange and an additional processor having a service control function connected thereto.

The present invention relates to an intelligent network capable of preventing inconsistency in call states managed by an electronic exchange and an additional processor.

[0003]

2. Description of the Related Art Conventionally, an electronic exchange has a service control function in the electronic exchange itself, and a call normality inspection processing program of each software function module inspects a call floating caused by a software error or the like. , The abnormal call was being released. Here, "call floating" refers to a phenomenon in which a call is made from the additional processor to the electronic exchange, but the electronic exchange does not process the call.

[0004]

In an intelligent network composed of an electronic exchange and an additional processor connected to the electronic exchange, when a call automatic normality check process is performed on a call for which service control is performed by the additional processor, In the conventional electronic exchange processing method, since an abnormal call is unilaterally found and released in the electronic exchange, the state of the call managed in the additional processor and the state of the call managed in the electronic exchange are There was a problem that inconsistency occurred.

The present invention solves such a problem, and an object of the present invention is to provide an intelligent network capable of preventing a mismatch between the states of calls managed by an additional processor and an electronic exchange. To do.

[0006]

SUMMARY OF THE INVENTION The present invention provides an intelligent network comprising an electronic exchange and an additional processor connected to the electronic exchange via a communication link for performing service control. A call from the additional processor to the electronic exchange, and means for requesting call information regarding the call to the electronic exchange when there is a call to be inspected. When a request for information is received, it is provided with means for editing call information relating to the target call and reporting it to the additional processor, and whether the target call reported from the electronic exchange to the additional processor is normal. And a means for releasing the resource of the target call when it is abnormal, and requesting the electronic exchange to release the target call. And a stage, the electronic exchange,
A means for releasing an abnormal call according to a release request from the additional processor is provided.

[0007] The additional processor includes means for periodically activating a normality check processing program for checking the normality of a call, and the means for searching has a call for which a predetermined time has passed without being processed. It is desirable to include means for searching whether or not.

[0008]

With respect to the call controlled by the additional processor in the intelligent network, the call to be inspected, for example, the call that has been held for a long time is searched,
If the call to be inspected exists, the call information regarding the target call is requested to the electronic exchange through the communication link connecting the additional processor and the electronic exchange, and the call information regarding the target call obtained from the electronic exchange and the addition are added. The call information managed in the processor is compared and inspected, and when an abnormal call is found, it is released. On the other hand, the electronic exchange releases the abnormal call according to the request of the additional processor and edits and reports the call information of the target call.

As a result, all resources related to the abnormal call managed by the additional processor and the electronic exchange can be released without any contradiction, and inconsistency may occur between the call states managed by the two. Can be prevented.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment of the present invention.

The embodiment of the present invention comprises an electronic exchange 2 connected to a plurality of communication lines 4 and an additional processor 1 connected to the electronic exchange 2 via a communication link 3 for performing service control. In addition, there is a method for synchronously activating a normality check processing program for checking the normality of a call, a means for searching whether there is a call to be checked, and a method to check if there is a call to be checked. The electronic exchange 2 is provided with means for requesting call information regarding the target call, and when the electronic exchange 2 receives the call information request from the additional processor 1, the call information regarding the target call is edited and the additional processor 1 And means for reporting to the additional processor 1 whether or not the target call reported from the electronic exchange 2 is normal, and releases the resource of the target call if abnormal. And a means for requesting the electronic exchange 2 to release the target call, and the electronic exchange 2 is provided with means for releasing the abnormal call according to the release request from the additional processor 1, and the searching means is a processing unit. It includes means for searching whether there is a call for which a predetermined time has passed without being processed.

Next, the operation of the embodiment of the present invention thus constructed will be described with reference to the drawings. FIG. 2 is a flow chart showing the operation flow of the automatic call normality check processing in the embodiment of the present invention.

First, the normality check processing program in the additional processor 1 is periodically activated (S1). The normality check program in the additional processor searches whether there is a call to be inspected, for example, a call that has been held for a long time, among the calls being controlled (S2), and the search result is obtained. If there is a call to be inspected, the additional processor 1
And requesting the electronic exchange 2 to edit the call information regarding the target call via the communication link 3 connecting the electronic exchange 2 and the electronic exchange 2 (S
3). The electronic exchange 2 edits the call information on the target call according to the request of the additional processor 1 (S4) and reports it to the additional processor 1 (S5). The additional processor 1 determines the normality of the target call by comparing and inspecting the call information obtained from the electronic exchange 2 and the call information managed in the additional processor 1, and determines whether the call is an abnormal call. For example, the resource related to the abnormal call managed in the additional processor 1 is released (S6), and the electronic exchange 2 is requested to release the abnormal call (S7). The electronic exchange 2 releases the abnormal call according to the request from the additional processor 1 (S8).

[0014]

As described above, according to the present invention, for a call whose service is being controlled by an additional processor in an intelligent network, a call normality inspection program periodically activated in the additional processor. Determines the normality of the target call and, if an abnormal call is found, instructs the electronic exchange to release the abnormal call, so that all resources related to the abnormal call managed by both the additional processor and the electronic exchange are inconsistent. It prevents the inconsistency between the state of the call managed in the additional processor and the state of the call managed in the electronic exchange, and promptly detects the call in the abnormal state. There is an effect that can be released.
