Method and arrangement for detecting fraud in telecommunication networks
Method and arrangement in a mediating function (204) for supporting detection of fraud in a network, when a network security function (200) is employed for analyzing activities in the network in view of predefined alert criteria, and a fraud detection function (202) is employed for analyzing e.g. ch...

description | Method and arrangement in a mediating function (204) for supporting detection of fraud in a network, when a network security function (200) is employed for analyzing activities in the network in view of predefined alert criteria, and a fraud detection function (202) is employed for analyzing e.g. charging information of users. When a first alert is received from a first one of the network security function and the fraud detection function, indicating that the predefined alert criteria of said first function have been satisfied, the alert criteria of the second one of said network security function and fraud detection function are modified based on the received first alert. Thereby, the network security and fraud detection functions can be correlated and made more efficient regarding accuracy and/or speed in detecting fraud. |
