Patent number: 10033769Abstract: A method, by an authentication unit of a wireless access network, allows anchoring of a data packet session of a user entity connected to the wireless access network to a packet core network of a mobile communications network. The user entity uses an access identifier for its identification in the wireless access network. 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. The request message contains an MAC address of the requesting user entity. 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 includes the sequence of digits used as mobile subscriber identifier.Type: GrantFiled: September 27, 2013Date of Patent: July 24, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Akbar Khan, Jade Mansour
