Abstract

Telecommunications systems embody means for establishing communications links between entities within that telecommunications system 1, 2, following an exchange of digital messages in accordance with a communications protocol, 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 8 within the protocol analyser 9, a sequence of messages exchanged in accordance with a correctly operating communications protocol may be learned, obviating the need for a pre-programmed data base. Training of the neural network 8 is by correct protocol messages stored in memory 5 and errored protocol messages stored in memory 7, generated by a data processor 6.
