A multi-stream concurrent transmission method, device and system

Abstract

A multi-stream concurrent transmission method, device and system, wherein the realization of the method includes: the master terminal establishes a connection with the media server through the first network, and sends a service request to the media server; After the connected slave terminal is established, send a cooperative transmission request to the distribution decision server, and establish a personal area network with the slave terminal to obtain the context information of the slave terminal, and send the context information of the master terminal and the slave terminal in the personal area network to the distribution decision server ; The context information of the master terminal and the slave terminal is used to execute the distribution decision; the result of the distribution decision is used to split the original data corresponding to the service request into first data and second data; the master terminal receives the first data sent by the media server to the master terminal One data, receiving the second data from the media server forwarded by the slave terminal; the master terminal reassembles the first data and the second data to obtain the original data. It can improve end-to-end throughput and network resource utilization.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, device and system for concurrent transmission of multiple streams. Background technique [0002] With the popularization of wireless networks, terminals can access the Internet (Internet) through a variety of wireless access technologies. At the same time, mobile terminals have also undergone evolution from single-mode, dual-mode to multi-mode, and have more and more wireless interfaces. On this basis, researchers are committed to integrating multiple access technologies of multi-mode terminals or multiple access technologies of different terminals in the personal area network, so that heterogeneous networks can carry a data service at the same time, which not only provides users with Faster transmission rate, and can improve network resource utilization, service reliability, and enhance user experience. The key to this technology is how to reaso...

Problems solved by technology

Since the SCTP protocol only allows one of the paths to be used for data transmission at the same time, the SCTP protocol cannot make full use of the network resources of multiple paths to improve the end-to-end throughput, so the utilization rate of network resources is low.
