This invention is related to S8 Home Routing (S8HR), under specification by the Global System for Mobile Communications (GSM) Association (GSMA) and 3rd Generation Partnership Project (3GPP).In a first aspect of the invention, a method is provided for enabling Lawful Interception (LI) when a wireless communication terminal performs S8HR roaming. The method comprises receiving, at a first LMISF from a first SGW serving the wireless communication terminal, IMS-related information of the wireless communication terminal required for performing LI, and providing, from the first LMISF upon the wireless communication terminal relocating to a second SGW serving the wireless communication terminal, the received IMS-related information of the wireless communication terminal required for performing LI, to a second LMISF associated with the second SGW.
