Abstract:
A method of detecting telephony fraud in the case of a mobile telephony device roaming at a visited network, the visited network being other than a home network of said mobile telephony device, cross-network triggering being available between said visited network and said home network. The method comprises detecting a non-correlation between said cross-network triggering and activity of said mobile telephony device, testing to find out if profile manipulation has taken place of a profile of said mobile telephony device held at said visited network, and upon detecting that profile manipulation has taken place taking remedial action such as blocking current calls and overwriting the manipulated profile.

Claim (Index 1):
Apparatus at a home network for detecting telephony fraud on a roaming telephony device, the roaming telephony device being at a visited network, the fraud involving cancellation of cross-network trigger signals by modifying a profile of said roaming telephony device at said visited network, the apparatus comprising a control unit at the home network, the control unit configured to communicate with the visited network and set the visited network to monitor changes in state of the roaming device between an idle state and a busy state and issue corresponding state change signals, the control unit further configured to receive said state change signals from the visited network and correlate said state change signals with cross-network triggering for mobile originated calls obtained from the visited network, the control unit in an event of non-correlation further configured to carry out an action that normally causes a cross-network trigger to be issued, and if no further cross-network trigger is issued as a result of such an action to determine that the roaming device is being fraudulently manipulated.
