一种选择性应答分组传输方法、装置及终端制造方法及图纸

本发明专利技术涉及移动通信领域，尤其涉及对多路径传输协议中的选择性应答ＳＡＣＫ分组进行传输的技术。一种选择性应答分组传输方法，包括：确定多路径中的一个单路径为选择性应答ＳＡＣＫ分组传输路径；将ＳＡＣＫ分组通过所述ＳＡＣＫ分组传输路径进行传输。本发明专利技术还提供了一种选择性应答分组传输装置。由于从多个路径中选择一个路径作为ＳＡＣＫ分组传输路径，并通过该ＳＡＣＫ分组传输路径将所有的ＳＡＣＫ分组发送到发送方，因此可以保证先发送的ＳＡＣＫ分组先到达，从而避免了到达发送方的ＳＡＣＫ分组乱序。并且选择往返时延最小的路径作为ＳＡＣＫ分组传输路径，可以加快ＳＡＣＫ分组到达发送方，从而提高多路径并发传输的端到端的吞吐率。

Selective response packet transmission method, device and terminal

The invention relates to the field of mobile communication, in particular to a technique for transmitting selective response SACK packets in a multipath transmission protocol. Including a selective response packet transmission method: identify a single path in multiple paths for the selective response of SACK packet transmission path; the SACK packet through the SACK packet transmission path transmission. The invention also provides a selective reply packet transmission device. Due to the choice of a path from multiple paths as SACK packet transmission path, and the SACK packet is sent to the sender through all the SACK packet transmission path, which can ensure to send the SACK packet arrives first, so as to avoid packet reordering at the sender SACK. And selecting the shortest path of the round-trip delay as the SACK packet transmission path can speed up the arrival of the SACK packet to the sender, thus improving the end-to-end throughput of multipath concurrent transmission.
