Abstract: The present technique relates to a Mediation Device (200) and a method for correlating lawful intercepted IMS signalling of a session involving a target UE registered in a first radio coverage area wherein the UE is supported by LTE Radio Access Technology at a session set-up. One object is to offer a technique and technology to overcome the problem for a LEA to correlate SIP signalling related to the original call with the SIP signalling generated during the Single Radio Voice Call Continuity, SRVCC, service execution. The object is achieved by providing the same correlation number CIN before and after SRVCC procedure. This can be accomplished by the Mediation Device and a method therein by checking the whole SIP signaling, from the UE REGISTER to the SRVCC INVITE message.

Abstract: Techniques for improving the operation of computing systems are described. Some implementations include a computer-implemented method. The method can include intercepting, at an intermediary computing system, messages communicated between a web server system and one or more client computing devices. A subset of the intercepted messages can be selected that are determined to commonly relate to a particular web transaction. The method can identify an expression pattern that occurs in the subset of the intercepted messages, and can determine that the identified expression pattern matches a first pre-defined expression pattern from among a plurality of different pre-defined expression patterns. A status of the particular web transaction can be determined based on the first pre-defined expression pattern that matches the identified expression pattern occurring in the subset of the intercepted messages. Information can be stored that indicates the determined status of the particular web transaction.

Abstract: Systems and methods for scalable and iterative deep packet inspection for communication networks are disclosed. According to one embodiment, a system comprises a home network and a visitor network in communication with the home network over an Internetwork packet exchange. The visitor network may have an intercept area with an intercept probe, a local packet data network gateway (PGW) and a local proxy-call session control function (P-CSCF). The system further includes a diameter edge agent that monitors signaling traffic in the visitor network passing to and from the home network. The system also has a targeting system in communication with the diameter edge agent that redirects the signaling traffic from the home PGW to the visiting PGW.
