ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a network analysis system and method.
BACKGROUND OF THE INVENTION
Telecommunications systems include sophisticated electronic switching equipment which is able to provide extensive data on the state and performance of the equipment and other aspects of a telecommunications system. Mobile telecommunications systems, in particular, are subjected to a wide variety of operating conditions which depend to a substantial extent on the movement and use of mobile telecommunications stations. The operating conditions of a mobile system include an unpredictable element and can give rise to a variety of different faults which need to be detected. The equipment of mobile telecommunications systems and, in particular, the base stations used in the systems, generate a considerable amount of data from which faults can be determined. It would be advantageous to be able to monitor a telecommunications network by accessing data which may be pertinent to fault determination and then analyse that data to detect faults.
SUMMARY OF THE INVENTION
In accordance with the present invention there is provided a network analysis system including:
means for obtaining parameter data generated by equipment of a telecommunications network, said parameter data representing operational parameters of said network,
means for processing said parameter data to generate symptom data from test procedures applied to said parameter data, and
means for generating fault data, representative of faults which may have occurred, on the basis of said symptom data and relationship data representative of the relationship between said symptom data and said faults.
Advantageously, said fault data may further represent the likelihood of said faults having occurred.
Preferably said system further includes a graphical user interface for establishing and adjusting said relationship data.
Preferably said system further includes means for generating occurrence data, representative of faults which probably have occurred, on the basis of said fault data.
Preferably said occurrence data generating means applies predetermined rules to said fault data to generate said occurrence data. Preferably said occurrence data generating means compares fault data associated with a plurality of said equipment having a predetermined relationship to generate said occurrence data. Depending on said relationship, the occurrence data generating means may remove from consideration fault data for one of said plurality of said equipment.
In accordance with the present invention there is also provided a network analysis system including:
means for obtaining parameter data generated by equipment of a telecommunications network, said data representing operational parameters of said network,
means for processing said parameter data to generate fault data representative of faults which may have occurred, and
means for generating occurrence data representative of faults which probably have occurred on the basis of said fault data.
The present invention also provides a network analysis method including:
obtaining parameter data generated by equipment of a telecommunications network, said parameter data representing operational parameters of said network,
processing said parameter data to generate symptom data from test procedures applied to said parameter data, and
generating fault data, representative of faults which may have occurred, on the basis of said symptom data and relationship data representative of the relationship between said symptom data and said faults.
The present invention further provides a network analysis method including:
obtaining parameter data generated by equipment of a telecommunications network, said data representing operational parameters of said network,
processing said parameter data to generate fault data representative of faults which may have occurred, and
generating occurrence data representative of faults which probably have occurred on the basis of said fault data.
