Abstract
A method and apparatus for providing lawful interception in an IMS network. A first node in an IMS network receives a message from a Lawful Intercept mediation system node instructing the first node to perform lawful interception on a target. The first node sends a subscribe request message towards a second node located in an IMS core network. The subscribe request message includes at least an identity of a service type to be monitored. The first node subsequently receives a notify message from the second node, the notify message including session information from which intercept related information can be derived. The first node then sends intercept related information towards the Lawful Intercept mediation system node.
