Title: LAWFUL INTERCEPTION IN A WI-FI / PACKET CORE NETWORK ACCESS
Abstract:
The invention relates to a method, by an authentication unit (300) of a wireless access network, to allow anchoring of a data packet session of a user entity (10) connected to the wireless access network to a packet core network of a mobile communications network (20), the user entity using an access identifier allowing the user entity to be identified in the wireless access network, wherein the access identifier is not used in the mobile communications network to identify a subscriber. A request message is received in which access to the wireless access network is requested, wherein the request message contains an MAC address of the requesting user entity (10). The MAC address is converted into a sequence of digits used as a mobile subscriber identifier with which the user entity is identified in the mobile communications network and a response message is transmitted accepting the access to the packet core network, the response message including the sequence of digits used as mobile subscriber identifier.
