  • Publication number: 20240048338
    Abstract: 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.

  • Patent number: 11665622
    Abstract: 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.

  • Patent number: 11405818
    Abstract: 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.

  • Patent number: 11304197
    Abstract: 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.

  • Patent number: 9471467
    Abstract: It is presented a method for evaluating an application intended to be installed in a wireless terminal of a cellular network. The method is performed in an application development device and comprises the steps of: obtaining performance data associated with an execution of the application in a test wireless terminal in a simulated or real cellular network, the performance data being obtained for each cellular data session of the execution of the application, each cellular data session being defined as a period when the test wireless terminal is in a cellular network connection state when data transfer is possible; and evaluating the performance data by comparing the in performance data with reference performance data, the comparison being based on the duration of each cellular data session.

  • Publication number: 20160057804
    Abstract: The embodiments herein relate to a method in a network node (101) for handling states associated with a wireless device (105) in a communications network (100). The network node (101) is connected to the wireless device (105) over a communications link (110). The communications link (110) is in a current state. The network node (101) receives, from the wireless device (105) information related to a data activity in the wireless device (105). The received information comprises at least information other than a current amount of data associated with the data activity. Based on the received information, the network node (101) determines a change associated with the current state.

  • Patent number: 8233436
    Abstract: 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.
