Abstract: A method in a network node for handling a traffic flow of a User Equipment, UE is provided. The network node is related to a local service cloud. The traffic flow is related to an application session to be served by the local service cloud. The network node identifies (202) a UE Internet Protocol, IP, address of the UE. When the identified UE IP address is used by another UE in a first Virtual Local Area Network, VLAN, comprised in the local service cloud, the network node selects (204) a second VLAN comprised in the local service cloud for local break out of the traffic flow of the application session to the local service cloud. In the second VLAN, the identified UE IP address is not used by another UE.

Abstract: It is disclosed a client node, a first network node, a second network node, and methods therefore, for enabling forward error correction, FEC, of data. In uplink, the client node is adapted to transmit a lightweight FEC packet, enabling to save radio resources. The first network node adapted to calculate a payload for the FEC packet and to append the payload to a “lightweight” FEC packet, and to transmit the thus modified FEC packet to an endpoint of the uplink. In the downlink, the second network node may be adapted to determine whether a received FEC packet is redundant or not, and is adapted not to transmit it as is, to an endpoint client node, if the FEC packet is redundant, enabling saving radio resources.

Abstract: A method and apparatus for providing data to a network terminal. A network node receives information relating to a first instance of a client running at the network terminal. Using the information, the network node concurrently runs a second instance of the client that emulates the first instance. Using the second instance, the network node generates a request for data required by the first instance. Before receiving a request for data generated by the first instance, the network node sends the request for data required by the first instance to a remote server and receives a response that includes the required data. The required data is then sent to the network terminal. The advantage of this is that the request for data required is generated before the network node receives a request from the network terminal. This allows the request to be handled more quickly.

Abstract: There is described a method for optimizing the distribution of data objects between caches in a cache domain of a resource limited network. User requests for data objects are received at caches in the cache domain. A notification is sent from each cache at which a request is received to a cache manager. The notification reports the user request and identifies the requested data object. At the cache manager, object information including the request frequency of each requested data object and the locations of the caches at which the requests were received is collated and stored. At the cache manager, objects for distribution within the cache domain are identified on the basis of the object information. Instructions are sent from the cache manager to the caches to distribute data objects stored in those caches between themselves.

A corresponding power adaptation device is also presented.

Abstract: A method of performing a compression operation on data in a mobile communication network. An intermediate node located between a mobile terminal and a mobility anchor point node, receives a data payload. If the intermediate node has access to compression information required to perform the compression operation, it performs the compression operation to generate a modified data payload and sends the modified data payload to a next node. If the intermediate node does not have access to compression information required to perform the compression operation, it sends the data payload to the next node. The compression operation may be data compression or de-compression.

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: 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.
