Publication number: 20170339600Abstract: The invention relates to a method for enabling relocation of a function for processing data packets of a flow associated with a device. The method is performed in an arrangement of a communication system, which is allocated as a proxy for control messages exchanged between an instance of the function for processing the data packets of the flow and a control instance controlling how the function processes the data packets of the flow. The method comprises obtaining (920) information indicating that the function for processing the data packets is relocated from a first instance to a second instance. The method further comprises forwarding (930) control messages received from the control instance to the second instance of the function for processing the data packets and vice versa, in response to the obtained information.Type: ApplicationFiled: December 19, 2014Publication date: November 23, 2017Applicant: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Dinand ROELAND, Conny LARSSON, Gunnar MILDH, Johan RUNE, Zoltán TURÁNYI

Patent number: 9826437Abstract: The invention relates to a method for relocating a first function for processing data packets of a flow associated with a device, from a source to a target instance. The method is triggered by an initiated relocation of a second function for processing data packets of the flow. The method comprises initiating (710) a first phase of a relocation method for relocating the first function, before the relocation of the second function is finalized. The method also comprises determining (720) whether to initiate a second phase of the relocation method based on information related to a progress of the relocation of the second function. When it is determined (720) to initiate the second phase, the method further comprises initiating (730) the second phase of the relocation method comprising the resumption of the processing of the data packets of the flow at the target instance of the first function.Type: GrantFiled: January 12, 2015Date of Patent: November 21, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (publ)Inventors: Dinand Roeland, Gunnar Mildh, Rashmi Purushothama, Johan Rune, Zoltán Turányi

Patent number: 9775183Abstract: A radio communication system and a method for assigning a short-lived Cell Radio Network Temporary Identifier, “CRNTI”, to a first user equipment performing random access to a radio network node are provided. The radio communication system registers the first user equipment as connected to the radio network node. A message for synchronizing the radio network node and the first user equipment with respect to the first time period is transferred. After the first time period has elapsed, the radio communication system maintains the first user equipment connected to the radio network node, and allows the short-lived CRNTI to be assigned to a second user equipment.Type: GrantFiled: January 3, 2012Date of Patent: September 26, 2017Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: György Miklós, Erik Eriksson, Johan Rune, Joachim Sachs, Zoltán Turányi, Niclas Wiberg

Patent number: 9398470Abstract: A method for deploying a policy from a 3GPP core network to a non-3GPP access network. The policy relates to a connection established from a mobile terminal to the 3GPP core network via the non-3GPP access network. A local IP address acquired by the mobile terminal during establishment of the connection is received at the 3GPP core network. At the 3GPP core network, establishment of a policy control session is initiated from the 3GPP core network to the non-3GPP access network. The received local IP address is used to determine the non-3GPP access network used for the connection with reference to shared IP addressing information. At the 3GPP core network, the policy is provided to the non-3GPP access network using the policy control session established as a result of the policy control session initiation step. The policy is for deployment in the non-3GPP access network in relation to the established connection.Type: GrantFiled: November 30, 2010Date of Patent: July 19, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Dinand Roeland, Johan Nielsen, Maria Belen Pancorbo Marcos, Zoltán Turányi

Publication number: 20160164952Abstract: A networking approach that maintains the benefits of ICN, but that can also be used to implement N-way commit protocols. In one aspect, a method performed by a routing apparatus is provided. In some embodiments, the method includes the routing apparatus receiving a request message transmitted by a requesting apparatus, the request message comprising a first content name. The routing apparatus forwards the first request message towards a publishing apparatus. After forwarding the first request message, the routing apparatus receives, via a network interface, a first response message transmitted by the publishing apparatus, the first response message comprising the first content name and a second content name. The routing apparatus forwards the first response message towards a requesting apparatus and links the second content name with a network interface identifier for identifying the interface via which the routing apparatus received the first response message.Type: ApplicationFiled: December 5, 2014Publication date: June 9, 2016Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Zoltán TURÁNYI, Börje OHLMAN
