Patent number: 11218955Abstract: The invention relates to methods and devices for enabling access to a plurality of communication networks (107-110). A wireless communication device (101) acquires (S101) information regarding network access capabilities of any modems with which the wireless communication device is equipped, as well as information identifying operator profiles available to each of said any modems, and establishes (S102) a connection with a network connectivity selection node (106) that can determine which network access is available for each of said any modems. The wireless communication device further reports (S103) the acquired network access capabilities and operator profiles of each of said any modems to the network connectivity selection node, and receives (S105), in reply to the reporting, a recommendation on which one or more of said any modems to use for connecting to one or more of the plurality of communication networks.Type: GrantFiled: October 13, 2017Date of Patent: January 4, 2022Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Tomas Hedberg, Patrik Teppo, Jari Vikberg

Patent number: 10158993Abstract: This relates to wireless communications, and in particular to the generation of keying material for security purposes. In particular, A method of performing authentication for a user terminal. The method comprises performing an Authentication and Key Agreement procedure for authenticating the user terminal in a cellular access network, wherein a core network of the cellular network comprises a Home Subscriber Server; determining in a Bootstrapping Server Function that the user terminal requires keying material for use outside the cellular access network. The method also comprises transferring authentication information directly from the Home Subscriber Server to the Bootstrapping Server Function; and generating session keys in the Bootstrapping Server Function using said authentication information, wherein said session keys are also generated in the user terminal.Type: GrantFiled: April 13, 2015Date of Patent: December 18, 2018Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Vesa Torvinen, Vesa Lehtovirta, Katharina Pfeffer, Patrik Teppo, Monica Wifvesson

Patent number: 10158764Abstract: A node for use in a telecommunication network. The apparatus comprises a service session handler for establishing and controlling service sessions on behalf of end users served by the telecommunications network, and a charging generation point for generating charging data for established sessions involving served users as originating users and for reporting that charging data to a network charging system. The apparatus further comprises a signalling message handler for receiving, in respect of a given service session between an originating and a terminating user, a signalling message sent by or on behalf of the terminating user, the signalling message containing cost apportionment data apportioning costs between the originating and terminating users, the signalling message handler being configured to pass that cost apportionment data to the charging generation point.Type: GrantFiled: May 28, 2013Date of Patent: December 18, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Jan Dahl, Ove Karlsson, Patrik Teppo, Robert Törnkvist

Patent number: 9264555Abstract: Apparatus for use within an IP Multimedia Subsystem, IMS, network to handle Session Initiation Protocol, SIP, messages. The apparatus comprises a receiver for receiving a SIP message from a peer IMS node, and a SIP message inspector for inspecting a P-Charging-Vector, PCV, header within a received SIP message in order to detect the presence within the PCV header of a parameter and associated handling determinator. The apparatus further comprises a SIP message handler for determining, on the basis of a handling determinator and without reference to said associated parameter, an action or actions to be applied to said parameter and associated handling determinator.Type: GrantFiled: July 5, 2011Date of Patent: February 16, 2016Assignee: ATC Technologies, LLCInventors: Jan Dahl, Ove Karlsson, Patrik Teppo
