摘要： In a multi flow HSDPA system comprising a RNC (402) and a plurality of NodeB's (404, 406), the present disclosure includes (re-) use of original active queue management, AQM, based congestion control, ABCC for a primary link (421). For every detected congestion, an end-user IP packet is destroyed. ABCC is not used for the secondary link (422), which means that application level TCP will not be informed about congestion on the secondary link (422). The radio link control, RLC, protocol data units, PDU, (432) are distributed among links based on the congestion status of the links. If secondary link (422) is congested then more packets will be transmitted on the primary link (421). This makes it possible to use TCP compatible congestion control for multi flow HSDPA, without the drawback that would result from TCP reacting unnecessarily on flow bitrate decrease.

摘要： Link capacity sharing and packet scheduling normally reside in the Internet protocol router (20) and cutoff parameters are forwarded to a call admission control unit (22) from a control unit (21), which accepts or rejects new flows based on the parameters. For each requested new flow, the traffic class is determined so that admission control can be performed and accepted packets are forwarded to an output port buffer (23) for scheduling to the output port scheduler (25), where the output link is bandwidth allocated into common and dedicated parts, the latter for elastic traffic only. Independent claims are included for a link capacity sharing device and for a method for determining a steady distribution of a Markov chain of dynamics in a network link.

摘要： Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

摘要： In one aspect, a method and apparatus are disclosed that can provide an efficient and robust HSDPA flow control solution. The RNC (110) can receive information regarding allowed data rate from the Node-B (120) for a data flow in a downlink direction. Based on the received data rate information and optionally based on other predetermined considerations, the RNC (110) adjusts the RLC PDU transmission window size for the data flow. When the RLC PDU transmission window is properly sized, reaction to congestion can be performed quicker relative to the existing Iub flow control.

摘要： A traffic concentrator ( 40 ) aggregates traffic in a radio access network. The traffic concentrator comprises an Asynchronous Transfer Mode (ATM) switch ( 42 ) and a control node ( 44 ) associated with the ATM switch. The Asynchronous Transfer Mode (ATM) switch which performs a switching operation for switching unspecified bit rate (UBR) virtual channels (VCs) carrying user traffic between plural virtual paths (VPs). The user traffic is transported as ATM Adaptation Layer 2 (AAL2) connections over the unspecified bit rate (UBR) virtual channels (VCs). The control node is arranged to process AAL2 signaling messages which concern the AAL2 connections included in the VCs for which the ATM switch performs the switching operation. The AAL2 signaling messages are carried in virtual channels which do not carry the user traffic and which are either originated or terminated at the control node. In one example implementation, the traffic concentrator aggregates traffic of plural base stations of the radio access network.

摘要： The invention concerns an efficient strategy for sharing link bandwidth in a mixed rigid-elastic traffic environment, as well as a strategy for sharing bandwidth among elastic traffic flows. The idea according to the invention is to share the link bandwidth among rigid and elastic traffic by dividing the link bandwidth into a first common part (C_COM) for elastic as well as rigid traffic and a second part (C_ELA) dedicated for elastic traffic. Subsequently, one or more admission control parameters (N_ELA) for the elastic traffic are determined in order to restrict the number of elastic traffic flows simultaneously present on the link. In particular, by formulating a call-level model for elastic traffic and determining a maximum number (N_ELA) of admissible elastic traffic flows based on call-level constraints for the elastic traffic related to throughput and/or blocking, the so-called throughput-to-blocking trade-off for the elastic traffic can be fully considered.
