Publication number: 20240048338Abstract: A method for selecting one or more secondary cells, SCells for supporting communication with a user equipment, UE, by carrier aggregation, CA. The one or more SCells is/are selected from a set of SCell candidates available for an access node. The method includes estimating a probability that the UE connected to a primary cell, PCell, of the access node is in coverage of an SCell in the set of candidates, predicting available resources for the SCell, calculating a CA value for the SCell based on the estimated probability, an estimated spectral efficiency and the predicted available resources, and calculating a CA value for each SCell of the set of SCell candidates, ranking the SCells of the set of SCell candidates based on their calculated CA values, and selecting one or more SCells for providing CA with the UE based on the ranking.Type: ApplicationFiled: December 23, 2020Publication date: February 8, 2024Inventors: Mats ZACHRISON, Peiliang CHANG, Tao CUI, Sven EKEMARK, Sofia SVEDEVALL, Henning WIEMANN, Linnea FAXÉN

Patent number: 11665622Abstract: A method performed by a method performed by a network node for performing admission control in a wireless communications network is provided. The network node serves a first and one or more second UEs. The network node receives (201) from the first UE, an access request for a radio resource for communication between the first UE and the network node. The network node further estimates (203) a first prediction of a requirement of the radio resource related to the access request, based on a measured initial data traffic between the network node and the first UE. The network node determines (205) a first threshold related to the first prediction, as a function of a measured data traffic load between the network node and the one or more second UEs. The network node then performs (206) admission control by deciding whether or not to admit the radio resource to the first UE, based on whether or not the first prediction exceeds the first threshold.Type: GrantFiled: December 20, 2017Date of Patent: May 30, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Mats Zachrison, Raimundas Gaigalas, Jonas Wiorek

Patent number: 11405818Abstract: A method performed by a network node for performing Congestion Control in a wireless communications network is provided. The network node serves a number of User Equipments, UEs, comprising a first and one or more second UEs. The first UE has a radio resource allocated for communication between the first UE and the network node. The network node estimates (203) a first prediction of a forthcoming usage of the allocated radio resource, based on a measured data traffic between the network node and the first UE. The network node further determines (205) a first threshold related to the first prediction, as a function of a measured data traffic load between the network node and the number of UEs. The network node then performs (206) congestion control by deciding whether or not to initiate a removal of the radio resource allocated to the first UE, based on whether or not the first prediction exceeds the first threshold.Type: GrantFiled: December 20, 2017Date of Patent: August 2, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mats Zachrison, Raimundas Gaigalas, Jonas Wiorek

Patent number: 11304197Abstract: A method performed by a network node for managing a radio resource between the network node and a first User Equipment, in a wireless communications network is provided. The network node serves a number of UEs, comprising the first UE and one or more second UEs. The first UE has a radio resource allocated for communication between the first UE and the network node. The network node estimates (203) a prediction of a forthcoming empty data flow related to the allocated radio resource, based on a measured data flow between the network node and the first UE. The network node further determines (205) a threshold related to the prediction, based on a measured data flow between the network node and the number of UEs. The network node then decides (206) whether or not to initiate a removal of the radio resource allocated to the first UE based on whether or not the prediction exceeds the threshold.Type: GrantFiled: December 20, 2017Date of Patent: April 12, 2022Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Mats Zachrison, Raimundas Gaigalas, Jonas Wiorek

Patent number: 8233436Abstract: A method of controlling the rate of traffic flow through an Iub interface of a Radio Network Controller is described. The method includes obtaining a licensed rate, which defines the maximum throughput permitted through the Iub interface, at the Radio Network Controller. The rate of traffic flow through the Iub interface and all Iu interfaces of the Radio Network Controller is measured, and the extent to which packet switched traffic flow through the Iub interface exceeds the licensed rate identified. If the packet switched traffic flow through the Iub interface exceeds the licensed rate, packets are dropped from traffic flow through the Iub interface to reduce the traffic flow to the licensed rate.Type: GrantFiled: February 8, 2007Date of Patent: July 31, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sandor Racz, Szilveszter Nádas, Mats Zachrison, Wenbiao Wu
