Abstract

A data processing apparatus is coupled to receive messages from a telecommunications network, in order to collate messages relating to the same transaction into a transaction record for further analysis. The apparatus receives messages from the networks having different formats (protocols). For each input message, a protocol adapter manager determines the protocol of the message and a matching key is generated by a protocol adapter supporting the particular protocol. The message is then added by the matching engine to a matching pending context (transaction record) if there is one. If there is no matching pending context, a new context is created by the matching engine. The protocol adapter also includes a timeout value for the particular protocol. If a pending context has had no new messages added to it for a time greater than the timeout value for that protocol, it is assumed to be complete and is output to an output manager. A purge of all pending contexts to see whether they are complete is carried out at intervals.
