Abstract

The invention discloses a multi-stream business concurrent transmission control method and device, and defects of unnecessary data retransmission caused by the fact that aggregation bandwidth resources cannot be fully utilized in transmission of utilizing multiple links by a terminal device carrying multiple communication interfaces are overcome. A sending end executes the following processing in the method: link information of each link between the sending end and a receiving end is acquired; transmission time delay of each link is predicted according to the link information of each link so that a transmission time delay estimation value of each link is acquired; a sequence of arrival of data packets at the receiving end on each link is calculated and predicted according to the transmission time delay estimation value of each link; and the distribution situation of the data packets on each link is scheduled according to the sequence of arrival of the data packets at the receiving end on each link. Unnecessary retransmission and link bandwidth congestion caused by disorder of the receiving end can be avoided by the embodiment of the invention.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for controlling concurrent transmission of multi-stream services. Background technique [0002] With the development of information technology, terminal equipment is generally equipped with a variety of communication interfaces, and it has become an urgent need to use multiple interfaces of the terminal to simultaneously transmit services to realize the aggregation effect of multiple links. However, due to the obvious differences in path bandwidth and transmission delay of multiple end-to-end concurrent links, the transmission throughput of multiple concurrent links is not significantly improved compared with that of a single link. The reason is that the data at the receiving end is out of sequence caused by link differences, which leads to unnecessary retransmissions and buffer congestion at the receiving end, which limits the throughpu...
