Control method and device for load transmission

Abstract

The invention discloses a load transmission control method and device. The control method includes: receiving a trigger event reported by a proxy server, including a first transmission delay of a first member transmission path and a second transmission delay of a second member transmission path, and When one is greater than the first delay threshold, report the trigger event; initiate a request to the packet data network gateway and obtain its feedback network information; control the proxy server to execute the corresponding load according to the first and second transmission delays and network information distribute. Through the above scheme, the present invention can more accurately instruct the congested member transmission paths to implement a specific load distribution scheme, so that the WiFi network can be used to share the load of the 4G network under the premise of ensuring good communication quality, so that the load of each member transmission path The transmission cost is minimized, reducing the communication cost and greatly improving the user's service experience.

Description

technical field [0001] The present invention belongs to the technical field of communication, specifically relates to the technical field of MPTCP (Multi Path Transmission Control Protocol, multi-path transmission control protocol), in particular to a control method and device for load transmission based on MPTCP. Background technique [0002] MPTCP is a TCP (Transmission Control Protocol, Transmission Control Protocol) enhancement technology proposed by IETF (Internet Engineering Task Force, Internet Engineering Task Force), which aims to allow a TCP connection to use multiple member transmission paths to transmit user The load of the equipment (User Equipment, UE), that is, the service packet flow, so as to maximize the use efficiency of transmission resources and improve the redundancy backup of transmission resources. [0003] Currently, MPTCP has been applied to wireless local area networks (Wireless Local Area Networks, WLAN) such as WiFi (Wireless Fidelity, wireless f...

Problems solved by technology

[0005] However, the above method only uses the congestion degree of each TCP member transmission path as the judgment condition for load distribution, so it is impossible to further judge the cause of congestion on the member transmission path, and cannot send specific load distribution to the congested member transmission path according to the cause , resulting in the degradation of the user's service experience in the scenario of load sharing of the transmission paths of each member
