Abstract: A method is provided of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers, the bearers each carrying data packets that relate to different ones of a plurality of services. In the method, for each bearer independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to identify and mark the data packets of each of the bearers that are conformant with a determined maximum information rate for the bearer. The data packets are forwarded for transport through the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets not identified by the profiling as being conformant are discarded, so as not to be transported through the transport network.

The first communication node (10?) transmits, over the first packet network, the remarked packet towards the destination node (10?,12).

Abstract: A congestion control method of a cellular communication system is disclosed. A first protocol data unit having a first sequence number is transmitted from a radio network controller to a base station via a transport network. The base station detects a congestion situation of the transport network by detecting loss of the first protocol data unit during transmission over the transport network. In response to detecting the congestion situation, a notification message indicative of the detected congestion situation is transmitted from the base station to the radio network controller via the interface of the transport network.

Abstract: A technique for operating an RNC of a communication network during a soft handover process of a mobile terminal between a first BS and at least one second BS that are connected to the RNC is provided. A method implementation of the technique comprises receiving, at a MAC protocol layer of the RNC, a first data frame stream from the first BS via a first data path and a second data frame stream from the second BS via a second data path. A relative delay between the data frames of the first and the second data frame stream regarding their arrival at the RNC is determined. The relative delay takes into account different systematic propagation durations from the first BS and the second BS to the RNC. At then the MAC protocol layer, data frames of the first and the second data frame stream are then merged into a third data frame stream which is transmitted to a protocol layer above the MAC protocol layer. The merging of the data frames is carried out in dependence on the relative delay.

Abstract: A method and a network node for increased utilization of a transport network link over a transport network of a HSPA system. The method comprises detecting a data packet loss in receiving a data packet flow, and detecting data delay information of data packets as received. The method also comprises determining if the detected data packet loss comprise non-congestive data packet loss, based on the detected data packet loss and the detected data delay information. In addition, the method comprises, when the detected data packet loss comprises non-congestive data packet loss, for a pre-determined time period, omitting to perform a congestion action affecting the data packet flow. By determining whether a data packet loss is non-congestive or not, an unnecessary reduction of the bitrate over the transport network can be omitted.

Abstract: A method in a communication node for handling a packet to a destination node in a communications network, and associated nodes. The communication node associates the packet with a remaining value, with the remaining value being a packet value reduced by a threshold value of an outgoing link from the communication node towards the destination node. The threshold value corresponds to a congestion level of the outgoing link. The communication node further handles the packet based on the remaining value, the handling including determining whether to drop or to transmit the packet along the outgoing link based on the remaining value.

Abstract: A method is presented of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers. For each of the bearers, independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to designate as ‘green’ data packets that are conformant with a predetermined maximum Information Rate for the bearer. One or more data packets is buffered for up to a predetermined maximum ‘green’ buffer time, during which if transporting the data packet would not cause the maximum information rate of the bearer to be exceeded, the data packet is designated as a ‘green’ data packet. The data packets are forwarded for transporting over the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets that are not designated as ‘green’ data packets are discarded, so as not to be transported through the transport network.

The method comprises the steps detecting (S12) data packets in the stream of data packets which are unnecessary retransmissions based on sequence numbers of the data packets, dropping (S14) data packets which are unnecessary retransmissions from the stream of data packets for setup of a modified stream of data packets, and transmitting (S16) the modified stream of data packets over a transmission link.

Abstract: Method in and a network node (160; 110; 401a, 600) for congestion management of a transport network (130) comprised in a wireless communications network (100). The wireless communications network (100) further comprises a base station (110; 401a) configured to receive data being transported via a data transport path (132; 404a,d) of the transport network (130) and to transmit the received data to one or more wireless devices (120) served by the base station (110; 401a). The network node obtains (302; 409; 501) an indicator indicating at least a risk for occurrence of downlink data congestion in the data transport path (132; 404a,d).

Abstract: A method of prioritizing packets for delivery over a transport network, where a guaranteed minimum information rate over the transport network is specified. The method comprises, for each bearer to be injected into the transport network from the mobile network, specifying a bearer information rate and marking packets up to that rate as conformant with the bearer information rate, and marking packets exceeding that rate as non-conformant. Multiple traffic-type streams from the mobile network are converged, each traffic-type stream comprising multiple bearers. Packets of traffic-type streams are inspected to identify packets marked as conformant and non-conformant, and at least a fraction of non-conformant packets are re-marked as conformant if the converged rate of conformant packets is less than said minimum information rate. The transport network prioritizes delivery of packets marked as conformant over those packets marked as non-conformant.
