Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a method for detecting an abnormality in a collection event of call processing in a storage program exchange system.

[Conventional technology]

This kind of collection event abnormality detection method is used as a test tool for detecting bugs in the software quality assurance test of the stored program exchange system.

In the conventional collection event abnormality detection method, it is checked whether or not the type of an appropriate event (calling, digit reception, connection type, response, disconnection, etc.) is counted for each call processing tax. Through each collection event,
In other words, there is no function to check the normality by combining the order and type of events.

[Problems to be solved by the invention]

Since the above-mentioned conventional method of detecting abnormalities of collected events does not check the normality by combining the order and type of events, even if the number of discrepancies between the events in the traffic report occurs, which call does which task. There is a problem that it is not easy to find that the count of events when running is missing or double counted.

[Means for solving problems]

The collection event abnormality detection method of the present invention provides an event collection memory corresponding to the call information memory in a storage program exchange system that performs call processing using a call information memory corresponding to a call, and the event collection memory stores the call Event types including call origination, digit reception, connection type, response, and disconnection that occur in the transition process are sequentially stored, and the stored sequence of the event types and the flow of the event types that can be taken in the call transition process A configuration in which a pattern is made into a tree and the stored event check data is compared, and the stored event type sequence is output for a call in which the event type sequence does not match any of the event check data patterns. Is.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, FIG. 2 and FIG. 3 showing an embodiment, the event collecting memory 1 is hunted when hunting a call information memory (not shown) in a call processing process and has a linkage with the call information memory. And the same number as the call information memory is prepared. Events A, B, C, D, E, and F are sequentially saved in the event collection memory 1 each time an event is counted. Events A to F are codes assigned in advance corresponding to types of events such as call origination, number reception, and connection type that occur during a call transition process. Pointer 2
Indicates the position of the latest event, and in FIG. 1, the pointer 2 indicates the number "6" of events AF.

In the call processing, the event check program (see FIG. 3) refers to the event check data shown in FIG. 2 and each time the event is saved in the event collection memory 1, the event value indicated by the pointer 2 (A to F). Check whether is normal. The event check data is data in which a correct flow of events is configured in a tree shape by a predetermined code for all possible events in a call transition process, and is stored in the main memory. If the events saved in the event collection memory 1 are not along the tree of the event check data, the contents of the call information memory which is regarded as abnormal and the link and the events collected for the call are output to the monitor, The event collection memory 1 is released. For a call that has no abnormality until the end of the call, the event collection memory 1 is released when the call information memory is released.

In Fig. 2, codes A, B, B ', B "to F indicate events. In the event check program, call processing tasks such as calling and receiving numbers collect events and the pointer 2 is incremented by +1 (increment). After that, the task is activated by each task, and the call information memory normally stores the calling party number, the sent selection signal information, the call transition state, and the like.

〔The invention's effect〕

As described above, according to the present invention, the collected event is checked through in response to a call. That is, the normality is checked by combining the order of collected events and their types. When abnormal event collection is detected, the event sequence collected for the call is output. As a result, it is possible to detect abnormal event collection through the call handling, and by tracing the event sequence output when an error is detected, it is possible to determine which task (at which point) in the series of call processing caused an error. , Can be easily clarified.

Claims (1)

[Claims] 1. A storage program switching system for performing a call process using a call-corresponding call information memory, wherein an event collecting memory corresponding to the call information memory is provided, and the event collecting memory generates an event generated during a call transition process. Event types including call, number reception, connection type, response, and disconnection are sequentially stored, and a sequence of the stored event types and a flow pattern of the event types that can be taken in the transition process of the call are set as a tree in advance. Collected event characterized by comparing stored event check data and outputting the stored event type sequence for a call in which the event type sequence does not match any of the event check data patterns Abnormality detection method.
