Abstract: A method for coordinated multipoint transmission includes collecting, in a serving CoMP-MA, channel state information, CSIs, reported by terminals served by eNBs within a cooperating set. The serving CoMP-MA selects dominant interferers as candidate transmitting eNBs for a terminal. CoMP joint transmission is initiated by forwarding, to the candidate transmitting eNBs, PDCP PDUs received from SGW and targeted to the selected terminal, and by setting the status of the terminal to joint transmission. High and low thresholds of PDCP buffers of the serving CoMP-MA are adjusted. As information required for air interface scheduling becomes available, the method includes extracting, in the serving CoMP-MA, radio resource allocations, RLC and MAC headers, references to user plane data, and precoding matrices from protocol entities, and forwarding them to the transmitting eNBs that have acknowledged PDCP PDUs, in order the transmitting CoMP-MA to prepare air interface for the terminal.

Abstract: The present invention provides a method, apparatus and a computer program product for improving TCP performance in mobile networks. The present invention discloses obtaining, at an intermediate network node, a quality measure of a connection between a content server and a user equipment, detecting, at the intermediate network node, whether the quality measure fulfils a predetermined condition, and, if the quality measure does not fulfill the predetermined condition, sending, by the intermediate network node, an acknowledgement message triggering a freeze mode of the connection between the content server and the user equipment.

Abstract: Various networks may benefit from suitable management techniques and systems. For example long term evolution networks and other wireless communication networks may benefit from a quality of experience aware transport self-organizing network framework. A method can include monitoring transport connectivity with respect to at least one base station (e.g. eNB) over a mobile backhaul. The method can also include detecting at least one degradation or anomaly in the transport connectivity of the at least one base station. The method can further include taking an appropriate network management action in response to the detected degradation or anomaly.

Abstract: Systems and techniques for transport control protocol proxy mangement during handover of a user device from one base station to another. One or embodiments of the invention provide mechanisms to create a transport control protocol (TCP) proxy during establishment of a new data bearer establishment at an eNodeB, wherein the TCP proxy is integrated with a packet data convergence protocol (PDCP) buffer of the new bearer. The TCP proxy is configured so as to manage delivery of pre-fetched data to a user device so as to prevent TCP connection collapse during handover of the user device from a source eNodeB to a target eNodeB.

Abstract: The present invention provides a method, apparatus, gateway and a computer program product for reducing overhead on voice traffic within a packet based communication system. The present invention discloses collecting a plurality of packets to be multiplexed in an aggregated frame, measuring a number of received packets within a predetermined time period, and, if the number of received packets reaches a predetermined value, sending the aggregated frame including the collected packets.
