  • Patent number: 10785677
    Abstract: Congestion control in a telecommunications network, in which a method of congestion control in a transport network is provided. A buffer state of a buffer is monitored by dynamically sampling the buffer such that the sampling rate is adjusted in dependence of the buffer state. Also, a condition indicative of congestion is determined in response to a change of the buffer state exceeding a predetermined limit. In response to determining the condition indicative of congestion, a congestion notification message is created. The created congestion notification message may then be transmitted to a second network node. The second network node may subsequently compensate for a detected congestion on the basis of a received congestion notification message.

  • Patent number: 10172034
    Abstract: Method and communication network node for enabling a radio base station to adjust a Radio Access Network, RAN, capability within a RAN, such as handover or scheduling, dependent on a data transport characteristics of a backhaul network, such as data transfer rate, network delay and bandwidth. The RAN and the backhaul network are parts of a telecommunication network, and the first communication network node is arranged in the telecommunication network to communicate data between the RAN and a core network node in the telecommunication network. By acquiring knowledge of variations of transport characteristics in backhaul networks, RAN capabilities may be adjusted, e.g. by performing handover of UEs to other radio base stations which have better backhaul transport characteristics. Thereby, user experience for the users of the UE may be increased. In addition, an operator of the communication network may make better use of installed transport capacity.

  • Publication number: 20180331781
    Abstract: A data block is acquired, the data block is encoded, and the encoded data block is sent addressed to a network receiving node. Feedback information is received from the network receiving node regarding decoding performance of the sent encoded data block, and based on the feedback information, it is determined whether the sent data block was successfully decoded by the network receiving node. When it is determined that the sent data block was not successfully decoded, an adjusted coding parameter value of the coding parameter is determined, the data block is encoded with the adjusted coding parameter value, and the adjusted encoding parameter value data block is sent addressed to the network receiving node. When it is determined that the sent data block was successfully decoded, a subsequent data block is encoded, and the encoded subsequent data block is sent addressed to the network receiving node.

  • Patent number: 10110467
    Abstract: A source network node performs routing path selection in a communications network by steps that include acquiring a dynamically changing metric value of at least one of a plurality of data routing paths extending from the source network node to a destination network node to which data is to be routed. A determination is made as to which of the data routing paths the data is to be routed on the basis of the acquired dynamically changing metric value of the at least one data routing path in order to satisfy at least one predetermined routing criterion. Routing of the data from the source network node to the destination node is then controlled to be performed over the determined data routing paths.
