Patent number: 10362597Abstract: A node (100, 200) of a cellular network controls sending of first uplink grants to a communication device (10). The first uplink grants indicate first uplink radio resources allocated to the communication device (10) and are sent in response to receiving scheduling requests from the communication device (10). Further, the node (100, 200) controls sending of second uplink grants to the communication device (10). The second uplink grants indicate second uplink radio resources allocated to the communication device (10) and are sent according to a configured periodicity. Depending on a periodicity of opportunities for transmission of the scheduling requests by the communication device (10) and the configured periodicity of sending the second uplink grants, the node (100, 200) controls an alignment of the sending of the second uplink grants with respect to the opportunities for transmission of the scheduling requests.Type: GrantFiled: August 26, 2014Date of Patent: July 23, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Eric Andersson, Ying Sun, Lotta Voigt

Patent number: 10219289Abstract: A method in a network node downloads an upcoming web page to a user equipment. The network node obtains a first value, relating to the upcoming web page, of a set of features. The features represent any one out of: the upcoming web page, the user equipment, and a web browser in the user equipment. The network node predicts whether it is beneficial regarding download time to activate an uplink grant pre-allocation for the user equipment for downloading the upcoming web page. The prediction is based on a relationship between the first value and of a second value of the set of features, which second value is related to a previously downloaded web page, and an evaluation whether it is beneficial regarding download time to activate the uplink grant pre-allocation for the previously downloaded web page. The network node provides the prediction to a base station.Type: GrantFiled: October 1, 2013Date of Patent: February 26, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Vincent Huang, Ying Sun, Lotta Voigt, Eric Andersson, Mona Matti

Patent number: 9867079Abstract: Embodiments herein relate to a method in a transmitting radio node (12) for handling data packets within a radio bearer in a radio communications network (1). The transmitting radio node (12) sets up, within a radio bearer, a logical sub-channel for each of at least two identified packet flows. The transmitting radio node (12) associates an identity to each data packet of respective identified packet flow, where the identity is indicating the logical sub-channel of the respective identified traffic flow. The transmitting radio node (12) transfers the data packets of respective identified packet flow in an order over a channel in the radio communications network (1), where the order of transferring is based on the identity of each data packet.Type: GrantFiled: January 26, 2012Date of Patent: January 9, 2018Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ann-Christine Eriksson, Paul Stjernholm, Lotta Voigt

Patent number: 9756652Abstract: A method performed by a communication network node is provided for scheduling of a User Equipment, UE, in a communication network which comprises the UE and the communication network node. The UE is arranged to communicate data on a plurality of bearers with the communication network node. In the method, one or more active bearers among the plurality of bearers are determined, the highest priority of the active bearers are determined, and a data transmission in uplink is scheduled for the UE based on the highest priority. By only taking active bearers in account when scheduling, UEs with non-active high priority bearer are prevented from performing free-riding traffic on lower prioritized bearers.Type: GrantFiled: March 14, 2013Date of Patent: September 5, 2017Assignee: TELEFONAKTIEBOLAGET L M ERICSSONInventors: Lotta Voigt, Ann-Christine Eriksson, Maria Hulström

Patent number: 9642156Abstract: A method in a transmitting radio node for scheduling service data flows within a radio bearer towards a receiving radio node in a radio communications network is provided. The transmitting radio node maps data packets of at least two service data flows within the radio bearer to a respective pre-scheduling queue at a PDCP layer, wherein each pre-scheduling queue is associated with a service or a service quality requirement of the respective service data flow. The transmitting radio node further pre-schedules the data packets of the respective pre-scheduling queue down to a scheduling queue at a RLC or a MAC layer. The transmitting radio node further schedules the data packets in the scheduling queue towards the receiving radio node. The transmitting radio node takes a prebuffer time of a data packet queued in the pre-scheduling queue into account when pre-scheduling and/or scheduling the data packets.Type: GrantFiled: November 30, 2012Date of Patent: May 2, 2017Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Ann-Christine Eriksson, Paul Stjernholm, Lotta Voigt

Patent number: 9622171Abstract: A method and network node of a radio network, for enabling a User Equipment (UE) to save power in radio communication with the network node. The network node sets a waiting threshold for the UE and communicates data with the UE over a radio link. The network node also obtains traffic characteristics pertaining to the radio communication, and predicts a waiting time until next data is to be communicated with the UE based on the traffic characteristics. The network node further triggers the UE to enter a Discontinuous Reception (DRX) sleep when the predicted waiting time is longer than the waiting threshold. Thereby, power can be saved in the UE by immediately going to sleep after the last data.Type: GrantFiled: October 6, 2014Date of Patent: April 11, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lotta Voigt, Eric Andersson, Mathias Sintorn

Publication number: 20160286605Abstract: The present disclosure concerns radio communication. More particularly, the present disclosure inter alia introduces methods and means for improved radio access bearer (RAB) release, particularly in situations when there is a RAB limitation requirement. According to one embodiment, a method is performed by a radio network node. The radio network node is handling a set of RABs. This set of RABs consists of one or more RABs. Information related to each RAB of the set of RABs is obtained (130). The obtained information is processed (140) to generate a predicted timing of a next data transmission for each RAB. Also, a ranking is determined (150) for each RAB. This ranking is determined based on the predicted timing. Furthermore, a subset of the set of RABs is selected (160) based on the determined ranking. The subset of the set of RABs is selected (160) in such way that a cardinality of the selected subset complies with a RAB limitation requirement.Type: ApplicationFiled: November 19, 2013Publication date: September 29, 2016Inventors: Lotta Voigt, Ann-Christine Eriksson
