Abstract: The disclosure relates to a method for handling congestion performed in a source node of a communication network. The communication network provides a communication path for traffic streams between the source node and a destination node, wherein the source node multiplexes two or more different types of traffic streams onto a single connection. The method comprises detecting congestion in the communication network along the communication path, determining whether there is a traffic differentiation in a network node along the communication path, and applying a connection-level congestion control for the case of determining that there is no network node performing traffic differentiation. The disclosure also relates to a source node, computer program and computer program product.

Abstract: The disclosure relates to a method and network node for controlling a plurality of flows of application data in a radio network. The plurality of flows and a cost measure associated with each flow is detected. The cost measure is an indication of an amount of radio resources required for supplying an amount of application data to an end-user of the flow. Further, key performance indicators associated with the plurality of flows are monitored. A key performance indicator is indicative of a supply of application data needed to maintain a satisfactory quality of experience for an application session associated with the flow. Further, scheduling decisions, to control scheduling of the plurality of flows, are made based on the cost measures and key performance indicators associated with the plurality of flows to optimize the quality of experience of the application sessions associated with the plurality of flows.

Abstract: Disclosed herein is a method, a serving node and a mobility node for relocating the mobility anchor for a mobile terminal 215a in a wireless communication system 200. The relocation comprises a request for redirecting a first bearer B-old for the mobile terminal 215a between the serving node 212b and a first mobility anchor 214a so as to create a new substantially identical second bearer B-new between the serving node 212b and a second mobility anchor 214b. In addition, the relocation comprises a transmission of a request to the first mobility anchor 214a for deleting the first bearer B-old and a transmission of a request to the second mobility anchor 214b for establishing the second bearer B-new.

Abstract: There is described a method and apparatus for sending data through one or more packet data networks. A stripped-down packet is sent from a packet sending node towards a cache node, the stripped down packet including in its payload a pointer to a payload data segment stored in a file at the cache node. When the stripped-down packet is received at the cache node, the pointer is used to identify the payload data segment from data stored at the cache node. The payload data segment is inserted into the stripped-down packet in place of the pointer so as to generate a full size packet, which is sent from the cache node towards a client.

Abstract: A method of delivering packets from a radio access network to a user terminal. The method comprises establishing a radio access bearer for transporting data to the user terminal from a radio layer control entity responsible for constructing downlink radio frames. Within the radio access network, an IP traffic flow destined for said user terminal is observed and a delivery priority determined for the IP traffic flow taking into account a user application to which the traffic relates. The delivery priority is dynamic ally adjusted in dependence upon the desired arrival time or delivery rate of packets within the IP traffic flow at the user terminal. With respect to other downlink user traffic to be sent over the radio interface, packets of the IP traffic flow are scheduled for transmission to the user terminal over the established radio access bearer, and or the scheduling weight of radio frames of the established radio access bearer adjusted, in accordance with the current delivery priority.

Abstract: A method for transferring a communication session between a source user device and a target user device in a communication network, where the communication session is established between the source user device and a server is proposed. An identifier of a user device is determined. A session modification request is then sent from the source user device to the server, where the request includes the identifier of the target user device. A capability of the target user device to handle the communication session is then checked. Next, if the target user device is capable of handling the communication session a further communication session between the server and the target user device is established.

Abstract: A method and apparatus for providing a data object from a Content Server to a client device over a Radio Access Network (RAN). A first property is determined that may affect the way in which the data object is to be transferred. A property of the data object is also determined. In response to the determined first property and the property of the data object, a characteristic of a transfer of the data object from the Content Server to the client device is amended. The data object is then provided from the Content Server to the client device. The method allows characteristics of the transfer of the data object to be changed to optimize transfer to the client device. Examples of the first property include properties in the RAN or client device instructions.

Abstract: A method is provided which introduces user plane caching over an interface between a first node in a radio access network and a second node in a core network. At the first node: receiving first uplink tunnel parameters relating to the second node, selecting first downlink tunnel parameters relating to the first node, sending the first uplink and downlink tunnel parameters to a cache node designated to the first node, receiving second uplink and downlink tunnel parameters relating to the cache node, and sending the second downlink tunnel parameters to the second node. A first tunnel is established between the first node and the cache node based on the second uplink tunnel parameters and the first downlink tunnel parameters, uplink user plane data is sent to the second node through the first and second tunnels via the cache node, and downlink user plane data is received from the second node.

Abstract: A method is presented of requesting and receiving content over a network for use at a device. A request for the content is sent (S1) from the device to a content server located in the network. A response is received (S2) at the device from the content server. The response provides a content readiness estimate for the requested content. The readiness estimate is an estimate of when the content will be ready for use at the device according to a predetermined criterion, based on network conditions affecting delivery of the content from the content server to the device. A content readiness indication is presented (S3) at the device to a user of the device. The readiness indication is derived in dependence upon the readiness estimate and indicates to the user when or whether the content will be or is ready for use at the device according to the predetermined criterion. An instruction is received (S4) at the device from the user indicating when the user wishes to commence use of the content at the device.
