    摘要: A radio access network node (24) comprises protocol data unit (PDU) formation logic (36); a PDU buffer (38); a concatenation timer (40); and a buffer readout mechanism (39). The protocol data unit (PDU) formation logic (36) serves, e.g., for segmenting incoming service data units (SDUs) to form protocol data unit (PDUs). The PDU buffer (38) stores one or more PDUs. The buffer readout mechanism (39) controls readout of contents of the PDU buffer (38). For example, when contents of a PDU in the PDU buffer (38) has not reach a predetermined fill level, the buffer readout mechanism (39) uses the concatenation timer for determining a delay for readout of the PDU from the PDU buffer (38). The delay provides opportunity for at least a portion of a yet-arrived SDU to be included in the PDU prior to readout of the PDU from the PDU buffer (38), and thereby reduce padding in an outgoing PDU.

    摘要: In a method of improved media frame transmission in a communication network. Initially a plurality of “original” or regular media frames are provided for transmission. According to the invention, robust representations of the provided regular media frames are generated and stored locally. Subsequently, one or more of the regular media frames is/are transmitted. The invention detects an indication of a loss of a transmitted media frame, and the idea is to transmit, in response to a detected frame loss, a stored robust representation of the lost media frame and/or a stored robust representation of a subsequent, not yet transmitted, media frame to increase the media quality.

    摘要: User equipment in a wireless communication system monitors scheduling information and locally detects a change in link data rate of the uplink channel based on the monitored scheduling information. In this way, a change in link data rate can be detected directly without significant delay. This direct or early detection of a rate change is then combined with an appropriate system reaction. The information of the detected change in link data rate is preferably utilized for adapting the application data rate of an IP application running in the user equipment. As an alternative, or as a complement, data packets are classified based on relative importance and selected for transfer of information over the uplink channel based on the classification of data packets and in dependence on the detected change in link data rate.

    摘要: A method of optimizing the timing offsets with which data frames are transmitted over the Iur/Iub interfaces of a UMTS Terrestrial Radio Access Network, UTRAN. The method comprises, for a given Iur/Iub interface or set of Iur/Iub interfaces over which identical user plane data is to be sent, defining a duration of a data frame receiving window for use by the receiving node(s), transmitting data frames from a sending node with an initial timing offset sufficient to ensure a likelihood that the frames will be received at the or each receiving node within the defined receiving window, reducing the timing offset at the sending node in a stepwise manner, and adjusting the timing offset at the sending node in response to the receipt of late Time of Arrival error reports at the sending node. In a second embodiment, the frame synchronisation of frames corresponding to speech services and data services is carried out by delaying the frames corresponding to speech services a fixed delay and the frames corresponding to data services a variable delay based on a received time of arrival feedback.
