Abstract: A method executed by an Intermediary Node arranged between a Client and a Server for participating in the setting up of a connection between the Client and a Server is described. In response to intercepting a first message, the method transmits from the Client and destined for the Server, and requests for a connection to be set-up between the Client and the Server.

Abstract: A method of congestion control (500) in a communications network is provided. The method comprises detecting congestion (501, 502) for data packets being transmitted along a data path between a sender and a receiver of the communications network, wherein the receiver accesses the communications network via a Radio Access Network (RAN), interrupting transmission (503, 505, 506) of data packets to the receiver during an idle period, and transmitting an indication (504) pertaining to the interruption of transmission to the RAN. Thereby, the RAN may use opportunities for switching to a lower radio state directly, or shortly after, the onset of the idle period, rather than triggered by an inactivity timer. In that way, utilization of air interface resources is improved and power consumption on the UE side is reduced. Further, a corresponding computer program, a corresponding computer program product, and a network node for congestion control in a communications network, are provided.

Abstract: The embodiments relate to an apparatus and method for streaming content to one or more user equipment devices in a telecommunications network, wherein the content is available for streaming at one of a plurality of different quality representations. The method comprises the step of receiving a request from a user equipment device, wherein the request is for delivery of a segment of the content at a first quality representation. It is determined whether the user equipment device is connected to a cell of the telecommunications network in which a congestion level of the cell is above a threshold level. If so, a fairness function is performed to determine if the segment of content should be streamed to the user equipment device at the requested first quality representation or a second quality representation. The segment of content is streamed to the user equipment device at the first quality representation or the second quality representation based on a result of performing the fairness function.

Further, a corresponding network node for throttling a media stream is provided.

Abstract: A solution for simplifying data transmission between a mobile device (MD) and a destination address (DA). In some embodiments, the solution includes a connector, associated with a gateway, that has access to a first mapping between a subscriber identity (SI) associated with the MD and a DA to which the data from the MD should be sent. The gateway is configured to send a second mapping between a temporary IP address of the MD and the SI associated with the MD to the connector. When the gateway receives data from the temporary IP address of the MD, the gateway requests information of the address to which the GGSN should route that data. Since, the connector can identify from which IP address the data is received, the connector can then retrieve the address by using the first mapping and the second mapping.
