Abstract

The invention discloses a multipath transmission control method, and the method comprises the following steps: under the condition that first equipment is associated with a first AP, judging whether the first equipment meets a preset AP switching condition or not, wherein the AP switching condition is used for indicating that the first equipment is disconnected with the first AP and is associated with a second AP; enabling the first device to perform data transmission with the second device through the first path after establishing a connection with the first AP, and performing data transmission with the second device through the second path after establishing a connection with the second AP; when the first device satisfies the AP switching condition, controlling the first device to perform data transmission with the second device through a third path, wherein the third path is a standby path established between the first device and the second device. According to the method, when AP switching is about to happen to the first device, the first device carries out data transmission with the second device through the third path, data transmission continuity is guaranteed, a low-delay service can be normally carried out, and user experience is improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a multipath transmission control method and control device. Background technique [0002] With the development of communication technology, mobile terminal devices such as smart phones often have the ability to access Wi-Fi network and cellular network at the same time, and multi-path transmission technology emerges as the times require. The multi-path transmission technology is to improve the throughput through the parallel transmission of multiple paths, or to realize the continuity and reliability of the business through the multi-path. For example, a common Multiple Path Transmission Control Protocol (Multiple Path Transmission Control Protocol, MPTCP). A transmission control protocol (Transmission Control Protocol, TCP) subflow can be established on multiple transmission paths between a mobile terminal device supporting MPTCP and a peer device (such as an application...
