| Abstract: |
Telecommunications systems embody means for establishing communications links between entities within that telecommunications system. These links are usually established following an exchange of digital messages in accordance with a communications protocol. Communications protocols are often sophisticated, involving a sequence of complex message exchanges. Known protocol analysers for testing communications protocols involve the use of data bases, which are pre-programmed with all possible combinations of messages sequences which correspond with the protocol to be tested. This is time consuming, expensive and inflexible. By using a neural network within the protocol analyser, a sequence of messages exchanged in accordance with a correctly operating communications protocol may be learned, obviating the need for a data base.

I claim:
1. A protocol analyser for analysing a communications protocol, comprising a monitor means for monitoring digital protocol messages which are exchanged in accordance with the communications protocol, and a neural network means being connected to the monitor means and arranged to operate in dependence upon first and second data, the first data appertaining to a set of monitored digital protocol messages and the second data appertaining to a set of errored digital protocol messages, which neural network means operates in either a training mode in which the neural network learns from the first and the second data to recognise the set of monitored digital protocol messages, or an analysis mode in which the neural network means analyses the first data appertaining to the monitored set of digital protocol messages, thereby providing the protocol analyser with means for learning a set of digital protocol messages corresponding to a communications protocol operating correctly, and for detecting whether a subsequently monitored communications protocol, corresponding to that learned communications protocol, is operating incorrectly.
