Abstract: The present invention describes a method for selecting a preferable codec mode for a connection between a first communication device (UE1) and a second communication device (UE2), where the devices communicate via a network. An element in the network observes a quality of said connection. The quality is based on a data error level of network resource. Based on the observation the network element judges a preferable operational mode of the codec, from a group of operational modes of the codec. The preferable codec mode is based on the quality level of the connection. In the preferred embodiment, if a Radio Network Controller (RNC) observes congestion by observing Real-Time Protocol (RTP) header information, the RNC judges a lower codec mode for the connection. The lower mode for the connection is judged if there is at least one gap in a sequence of detected packets.

Abstract: The invention relates to the generation of error correction data for available data packets and to the reconstruction of missing data packets based on available data packets and available error correction data. In order to enable an efficient error correction, the data packets are distributed at an encoding end to at least one block of data symbols, each data symbol being of equal size. Then all data symbols of a respective block are used in an encoding operation for forming a respective one of at least one error correction symbol for this block. At a decoding end, received data packets are distributed again to a block of data symbols and missing data packets are reconstructed based on these data symbols and on error correction symbols associated to the block.

Abstract: A sender in a wireless network may adjust the encoding bit rate of the transmitted content and/or the transmission bit rate of the content based on the predicted future channel throughput at a predicted future geographical position of a client mobile device, such as a cellular telephone. By appropriately adjusting the bit rate prior to the client mobile device experiencing the predicted low throughput, the likelihood of continuous content consumption by the client mobile device, even while experiencing the predicted low throughput conditions, may be increased. The prediction may be performed at the network side and/or at the client mobile device side.

Abstract: To support a forward error correction scheme, in which a code of the forward error correction scheme is employed at a transmitting end for encoding data for a transmission to a receiving end, the transmitting end compresses at least one binary parity check matrix associated to the employed code of the forward error correction scheme. The transmitting end then provides the compressed binary parity check matrix for a transmission to the receiving end. The receiving end receives the compressed binary parity check matrix and decompresses it for use in a forward error correction based on encoded data received from the transmitting end.

Abstract: For the notification of a receiving device about a forthcoming transmission session, an identifier of one of various possible types of identifiers in a transmission session is mapped to a transmission session identifier field. This field is used for notifying the receiving device. Further, a repetition value is added to the transmission session identifier field, which indicates whether the forthcoming transmission session is new or not. Further, the receiving device may release context data stored for a particular transmission session identifier, if an acquisition of data in transmission sessions identified by the transmission session identifier can be terminated.
