Method, apparatus, and system for providing encryption or integrity protection in a wireless network
Patent number: 10454686Abstract: A core network node identifies a non-USIM based authentication procedure to be utilized by a wireless communication device, WCD, being served by the core network node. The node obtains a session key associated with the identified non-USIM based authentication procedure. The node converts the session key associated with the identified non-USIM based authentication procedure to i) a first key, K1, for use by the WCD and a base station serving the WCD to derive an encryption or integrity protection key, Kenc/int, for enabling encryption or integrity protection of a communication between the WCD and the base station or ii) a second key, K2, for use by the WCD and the core network node to derive the first key K1. The node then send i) K1 to the base station or ii) K2 to another core network node that is configured to derive K1 from K2.Type: GrantFiled: April 8, 2016Date of Patent: October 22, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Gunnar Mildh, Henrik Basilier, Torbjörn Cagenius, Gunnar Nilsson, Stefan Rommer, Lennart Norell, Göran Rune, Ann-Christine Sander -

Patent number: 9749365Abstract: A method and apparatus for managing a HOLD announcement in a communication network. At an Application Server, AS, a message is received from a user terminal, the message comprises of an indicator, specifying whether the AS should provide a HOLD announcement in the event of a change in direction of a media stream between the user terminal and a further node during a session. The AS stores the indicator in a memory. Upon determination that a change in direction of the media stream has occurred, the AS determines, from the indicator, whether or not to provide the HOLD announcement to the further node.Type: GrantFiled: April 3, 2012Date of Patent: August 29, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Mikael Forsberg, Jörgen Axell, Lennart Norell
