A method for data communication between a first node and a second node over a data path includes determining one or more redundancy messages from data messages at the first node using an error correcting code and transmitting messages from the first node to the second node. The transmitted messages include the data messages and the redundancy messages. The method includes, receiving, at the first node, a first plurality of messages including messages indicative of a rate of arrival at the second node of the messages transmitted from the first node and messages indicative of successful and unsuccessful delivery of the messages transmitted from the first node to the second node. A first transmission limit and a second transmission limit are maintained according to the first plurality of messages. Transmission of messages from the first node to the second node is limited according to the maintained first transmission limit, and according to the second transmission limit.

Dynamic setting of FEC in eMBMS video streaming

Dynamic forward error correction (FEC) setting is discussed in which the network determines a FEC percentage for each video segment of a video streaming service, based on consideration of the transfer length of the video segment and the allocated bandwidth. When the transfer length and allocated bandwidth reflect transmission of less than peak bandwidth, the network will determine a higher FEC percentage that uses the otherwise wasted bandwidth to transmit additional redundancy symbols. The additional redundancy symbols increase the error recovery rate when collisions occur between streaming video reception and page monitoring occasions of other networks in multi-network, multi-subscriber identification module (SIM) mobile devices. A network entity may then transmit the dynamic FEC percentage for each video segment in the file description table (FDT) associated with the video streaming service.

Provided is a generating apparatus generating error-correcting code for data packet including: a first determining unit configured to determine a redundancy range for the error-correcting code; a second determining unit configured to determine a combination of a plurality of interleaving lengths indicating an interval of a plurality of data packets for which the error-correcting code is generated; and a generating unit configured to generate the error-correcting code for the data packet, based on a combination of the plurality of interleaving lengths determined by the second determining unit, wherein the second determining unit determines the combination of the plurality of interleaving lengths, such that a total redundancy of the error-correcting codes for the data packets corresponding to the combination of the plurality of interleaving lengths falls within a range of redundancy determined by the first determining unit.

PACKET CODING BASED NETWORK COMMUNICATION

A method for data communication between a first node and a second node includes forming one or more redundancy messages from data messages at the first node using an error correcting code and transmitting first messages from the first node to the second node over a data path, the transmitted first messages including the data messages and the one or more redundancy messages. Second messages are received at the first node from the second node, which are indicative of: (i) a rate of arrival at the second node of the first messages, and (ii) successful and unsuccessful delivery of the first messages. A transmission rate limit and a window size are maintained according to the received second messages. Transmission of additional messages from the first node to the second node is limited according to the maintained transmission rate limit and window size.
