  • Patent number: 10079771
    Abstract: A method of congestion control (500) in a communications network is provided. The method comprises detecting congestion (501, 502) for data packets being transmitted along a data path between a sender and a receiver of the communications network, wherein the receiver accesses the communications network via a Radio Access Network (RAN), interrupting transmission (503, 505, 506) of data packets to the receiver during an idle period, and transmitting an indication (504) pertaining to the interruption of transmission to the RAN. Thereby, the RAN may use opportunities for switching to a lower radio state directly, or shortly after, the onset of the idle period, rather than triggered by an inactivity timer. In that way, utilization of air interface resources is improved and power consumption on the UE side is reduced. Further, a corresponding computer program, a corresponding computer program product, and a network node for congestion control in a communications network, are provided.

  • Patent number: 9356858
    Abstract: In one embodiment, a data aggregator discovery (DAD) message may be distributed by an associated data aggregator, the DAD message identifying the initiating data aggregator, and comprising a recorded route taken from the data aggregator to a receiving particular node as well as a total path cost for the particular node to reach a root node of the DAG through the recorded route and via the data aggregator. The receiving particular node determines a path cost increase (PCI) associated with use of the data aggregator based on the total path cost as compared to a DAG-based path cost for the particular node to reach the root node via the DAG. If the PCI is below a configured threshold, the particular node may redirect traffic to the data aggregator as source-routed traffic according to the recorded route. The traffic may then be aggregated by the data aggregator, accordingly.
