Patent number: 9331951Abstract: A method and network management node for determining the managed nodes on a path from a given source node to a given destination node based on a statistical inference of traffic volume reports available from the nodes. Traffic counts from Performance Management (PM) counters are collected from all managed transport nodes including the source and destination nodes. Based on the observed pattern of traffic volume received from the PM counters, the most likely matching path from a given source to a given destination is selected. If the traffic counts are insufficient to establish a path with adequate certainty, the method may optionally generate additional traffic from the source node to the destination node to increase the reliability of the path determination.Type: GrantFiled: March 25, 2014Date of Patent: May 3, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Peter Vaderna, Péter Benkõ, András Veres

Patent number: 8923117Abstract: For implementing handling of congestions in a mobile network, a base station (100), e.g., an evolved Node B, is provided with at least one congestion controller (400, 400?). The congestion controller (400, 400?) operates in relation to data packets which are received from a transport network. The base station (100) then transmits the data packets on at least one radio link, which may be accomplished by using one or more scheduling queues (402) and a radio interface scheduler (410). A bitrate detector (404) measures a bitrate of the received data packets, and a bitrate limit calculator (408) calculates, on the basis of the measured bitrate, a maximum bitrate for transmission of the data packets on the radio link. A congestion detector (406) is used to detect a congestion in the transport network. In response to the detected congestion, the radio interface scheduler (410) schedules transmissions on the at least one radio link to meet the calculated maximum bitrate.Type: GrantFiled: October 4, 2011Date of Patent: December 30, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Sándor Rácz, László Hévizi, Szabolcs Malomsoky, Szilveszter Nádas, András Veres

Patent number: 8837279Abstract: A technique for controlling data transmission over a connection employing congestion control is provided. The technique comprises two basic aspects: Detecting a decrease of Round Trip Time in respect of the connection, wherein the detection is facilitated by comparing a short-term Round Trip Time average with a long-term Round Trip Time average (302); and, in response to a result of the detection, adjusting the congestion control so as to increase the data transmission rate (304). Particularly, adjusting the congestion control includes enabling a data transmission rate that is (even) higher than what would have been allowed by any conventional, congestion control. In effect, the present technique may ‘push’ the conventional congestion control when it is not increasing the data transmission rate fast enough.Type: GrantFiled: June 6, 2008Date of Patent: September 16, 2014Assignee: Optis Wireless Technology, LLCInventors: Gabor Nemeth, Ferenc Kubinszky, Andras Veres, Gergely Biczok, Peter Tarjan
