摘要： 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.
摘要翻译：本发明描述了一种用于选择第一通信设备（UE1）和第二通信设备（UE2）之间的连接的优选编解码器模式的方法，其中设备经由网络进行通信。网络中的元素观察到所述连接的质量。质量基于网络资源的数据错误级别。基于观察，网络元件从编解码器的一组操作模式判断编解码器的优选操作模式。优选的编解码器模式基于连接的质量水平。在优选实施例中，如果无线网络控制器（RNC）通过观察实时协议（RTP）报头信息来观察拥塞，则RNC为连接判断较低的编解码方式。判断连接的较低模式是否在检测到的分组的序列中存在至少一个间隙。

摘要： A hybrid-padding approach for arranging variable size data packets for error correction encoding and decoding is disclosed. The approach can involve arranging the data packets in columns and rows and selecting the row size to minimize the amount of padding required. If data packet is smaller than the number of rows the data packet is inserted into the column and the remaining rows are padded. If the data packet is larger than the number of rows, the data packet is allowed to span multiple columns with the last column being padded if necessary. The data packets can include parameters, such as a source block number, packet length, and starting column number, and the error correction packets can include parameters, such as, a source block number an N, a K, the starting column number, and the number of row, to signal the hybrid-padding message.
