  • Patent number: 10805831
    Abstract: A method and system to help control CoMP service in a V-RAN arrangement. The load on a cell site's fronthaul network interface between the cell site's RRH and the cell site's BBU is determined. And in response to detecting that the fronthaul load is threshold high, a limit will be imposed on application of CoMP service involving the cell site. For example, in response to detecting that the cell site's fronthaul network interface is threshold highly loaded, (i) the cell site could be made to use decentralized joint processing rather than centralized joint processing, (ii) a lower coverage strength threshold could be imposed as a basis to trigger CoMP service involving the cell site, and/or (iii) the quantity of uplink communication that is subject to CoMP service involving the cell site could be limited.

  • 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.
