Publication number: 20240049128Abstract: A method performed by a first network node for controlling power consumption in a second network node in a wireless communications network is provided. The second network node is operating in a first power consumption level out of multiple power consumption levels. The first network node 111 obtains (501) one or more performance parameters related to data traffic performance of User Equipment (UE) connections served by the second network node during a time interval. The first network node 111 determines (502) a proportion of the UE connections that are associated with a performance parameter exceeding a first threshold. The determination is based on the obtained one or more performance parameters. The first network node 111 decides (503) whether or not to switch from the first power consumption level to a second power consumption level out of the multiple power consumption levels.Type: ApplicationFiled: December 30, 2020Publication date: February 8, 2024Inventors: Reiner Ludwig, Pål Frenger, Jonas Bengtsson

Patent number: 11558879Abstract: For efficiently handling network traffic via a fixed access, classification of UL data traffic in a communication device may be accomplished in a reflective mode by detecting identifiers of outgoing uplink data packets which are complementary to identifiers of incoming downlink data packets. The downlink data packets are already assigned to the traffic classes. The outgoing uplink data packets carrying the complementary identifier are assigned to the same traffic class as the incoming downlink data packets. For this purpose, the communication device is provided with a traffic classificator. In the reflective mode, the traffic classificator locally generates uplink packet classification rules by monitoring received downlink data packets.Type: GrantFiled: February 26, 2021Date of Patent: January 17, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Reiner Ludwig, Hannes Ekström

Patent number: 11317314Abstract: To handle network traffic, a Deep Packet Inspection (DPI) node receives, from a Policy and Charging Rules Function (PCRF) network node, packet inspection control data that maps a specific service to an identifier. The DPI node identifies that a data packet pertains to the specific service. The identifying comprises performing DPI on at least a data section of the data packet. The DPI node notifies the PCRF network node that the DPI node received the data packet and that the data packet pertains to the specific service. The DPI node marks the data packet with the identifier in accordance with the packet inspection control data received from the PCRF network node.Type: GrantFiled: December 17, 2019Date of Patent: April 26, 2022Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Reiner Ludwig, Hannes Ekström

Patent number: 10785784Abstract: A service class for a transmission of data packets between a service entity and a user equipment is selected from a plurality of service classes. A first transmission context is established between a core network node and the user equipment, and is associated with a first set of attributes for defining a first quality of service for the transmission. Furthermore, a second transmission context is established between an access node and the user equipment, and is associated with a second set of attributes for defining a second quality of service for the transmission. The selected service class determines the first set of attributes by a first unique mapping function performed in the core network node and the selected service class determines the second set of attributes by a second unique mapping function performed in the access node.Type: GrantFiled: October 3, 2017Date of Patent: September 22, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Reiner Ludwig, Per Willars, Hannes Ekström

Patent number: 10511536Abstract: In a mobile communication environment, the data traffic is mapped to a number of bearers. In a downlink direction, this is accomplished by filtering data packets on the basis of an identifier which is included into the data packets in response to packet inspection. In the uplink direction, a mirroring function is applied which detects incoming data packets, which are received on one of a plurality of bearers and have a first identifier, and outgoing data packets having a second identifier which is complementary to the first identifier. The outgoing data packets having the complementary second identifier are routed to the same bearer from which the incoming data packets are received.Type: GrantFiled: December 15, 2014Date of Patent: December 17, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Reiner Ludwig, Hannes Ekström
