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: A method and apparatus for handling data compression in a mobile communication network. A node located between a mobile terminal and a mobility anchor point determines compression information relating to data transferred between the node and the mobile terminal. The node then sends the compression information to a network repository node for storage and retrieval by a further node in an event that subsequent mobility of the mobile terminal leads to transferring data between the mobile terminal and the further node.

Abstract: The invention relates to a method in a first communication node in a wireless communications network comprising a plurality of second communication nodes for enabling a central processing of local data from second communication nodes in the network. The first communication node establishes (82) an intemode connection in a radio access network of the wireless communications network to a second communication node wherein information is sent of a virtual cell of the first communication node. The first communication node then requests (84) and receives (86) local information from the second communication node. The received local information is then processed (88) into processed data to be used to centrally process the local information of the second communication node. For centrally processing the local information, the processed data is transmitted (90) to a third communication node.

Abstract: A method in a transmitting radio node for scheduling service data flows within a radio bearer towards a receiving radio node in a radio communications network is provided. The transmitting radio node maps data packets of at least two service data flows within the radio bearer to a respective pre-scheduling queue at a PDCP layer, wherein each pre-scheduling queue is associated with a service or a service quality requirement of the respective service data flow. The transmitting radio node further pre-schedules the data packets of the respective pre-scheduling queue down to a scheduling queue at a RLC or a MAC layer. The transmitting radio node further schedules the data packets in the scheduling queue towards the receiving radio node. The transmitting radio node takes a prebuffer time of a data packet queued in the pre-scheduling queue into account when pre-scheduling and/or scheduling the data packets.

Abstract: Embodiments herein relate to a method in a transmitting radio node (12) for scheduling service data flows within a radio bearer towards a receiving radio node (10) in a radio communications network (1).

According to exemplary embodiments, an apparatus acting as a first radio base station (macro or femto) (800, 900) is configured to acquire information including a scheduling scheme indicating information on how radio resources are allocated in second radio base station (femto or macro). The information is then used by a scheduler to allocate radio resources which are disjoint the radio resources already allocated by the scheduler of second radio base station.

Abstract: A method and apparatus for data compression in a mobile communication network. A node performing data compression on a downlink towards a mobile terminal compresses data based on an identity of a decompression node. A determination is made that the mobile terminal is no longer receiving data from the decompression node owing to mobility the mobile terminal. An identity of a further decompression node from which the mobile terminal receives data is determined, and data is compressed based on the identity of the further decompression node. The node performing compression can therefore dynamically adapt to mobility of the terminal, potentially resulting in a shorter learning phase.

The user plane data handling node receives the compression ratio and/or content information, and handles the user plane data in dependence upon the compression ratio and/or content information.

The transmitting radio node (12) transfers the data packets of respective identified packet flow in an order over a channel in the radio communications network (1), where the order of transferring is based on the identity of each data packet.

The capacity manager (60) is configured to monitor a network condition of the radio access network (24). The radio resource manager (60) is configured to make a decision whether to make a transition from the first state to the second state by determining whether (1) a cost of remaining in the first state is greater than (2) a cost of switching to the second state, and wherein the radio resource manager is configured to take the network condition into consideration when making the decision.

Abstract: The technology pertains to wireless telecommunications systems in which a quality of service is handled for a service provided to a user equipment when the user equipment transitions from being served by a source network to being served by a target network. The quality of service is handled even if the source and the target networks implement proprietary QCIs. In general, a source QCI, which may be proprietary to the source network, is remapped to a predetermined QCI that identifies a set of predetermined QCI characteristics whose values are similar to the source QCI characteristics identified by the source QCI. The predetermined QCI and the set of predetermined QCI characteristics are used by the target network to provide the service to the user equipment after the transition.
