Abstract: A method for localized congestion exposure within a local loop in a cellular network that is performed by a localized congestion exposure receiver node of the local loop. The method includes receiving downlink packets destined for a downstream user device. The downlink packets have headers that indicate a level of congestion experienced by the downlink packets. The headers also indicate a level of expected downstream congestion declared by an upstream node. The method also includes forwarding the downlink packets to the downstream user device through a wireless connection. The method further includes sending packets upstream that have feedback indicative of the level of congestion experienced by the downlink packets and any congestion experienced within the localized congestion exposure receiver node.

Abstract: The proposed technology relates to methods and radio network nodes for Explicit Congestion Notification, ECN, marking of user traffic in wireless communication networks. For example, a method performed by a sending radio network node (10) comprises the step of monitoring (S10) a congestion metric on a data radio bearer, and the step of transmitting (S20) control information indicating traffic congestion on the same data radio bearer, based on the monitored congestion metric, to a receiving radio network node (20).Further, a method performed by a receiving radio network node (20) comprises the step of receiving (S100) control information indicating traffic congestion on a data radio bearer, based on a congestion metric, from a sending radio network node (10), and the step of marking (S200) next ECN-capable user packet of the user traffic on the same data radio bearer with ECN marking, based on the received control information.

Abstract: A method of controlling a receiver of a data unit communication from a data source is described, said receiver being associated with a first terminal of a data unit communication network providing said first terminal with a transport service characterized by a set of values associated with respective service quality parameters, said service quality parameters comprising a Guaranteed Bit Rate (GBR), said data source being associated with a second terminal. The method comprises determining, by the receiver, whether a received data unit contains an Explicit Congestion Notification (ECN). If said ECN is detected, the method further comprises sending, from the receiver, to said data source a message for adjusting a data transmission rate of said data source, said message indicating as an upper bound for said data transmission rate a value corresponding to a value associated with the GBR for said first transport service.

Abstract: There is provided a method performed by a first network node for enabling network congestion management in a wireless network. The method comprises the step of encapsulating and sending user packets in a tunnel to a second network node, wherein each packet comprises information related to a byte loss volume for the tunnel. The method further comprises the step of receiving congestion volume information for the tunnel from the second network node. The method also comprises either the step of applying network congestion policing for the tunnel based on the received congestion volume information, or alternatively the step of forwarding the received congestion volume information to a third network node, to enable network congestion policing for the tunnel based on the received congestion volume information.

Abstract: A flow management method comprises receiving (210) of incoming downlink packets. The received downlink packets are classified (220) in sub-flows, based on information that is available in a header of respective such received downlink packet. The downlink packets of each sub-flow are queued (230) in a respective sub-flow queue. Downlink packets are extracted (250) from the sub-flow queues into a common outgoing flow. A sub-flow queue from which no downlink packets yet have been extracted is prioritized (240). The extraction comprises assigning of an indicator of last service occasion to each sub-flow queue when a predetermined amount of data has been extracted from said sub-flow queue. When no prioritized sub-flow queues are present, the sub-flow queue with the earliest last service is selected. When a prioritized sub-flow queue is present, the prioritized subflow queue is selected. The downlink packets of the common outgoing flow are sent (260).

Abstract: In order to efficiently handle the switch between user media and announcement media, a basic step is to first determine a configuration of the user media. Next, a configuration of the announcement media to be presented is determined based on the determined user media configuration. Subsequently, the announcement media is configured according to the announcement media configuration, and the configured announcement media is finally sent to the intended user. In this way, the overall appearance or sound of the announcement will be virtually the same as or at least similar to the overall appearance or sound of the user media, preferably without distortions. This allows the user to perceive the announcement as clearly as possible.
