Abstract

The embodiment of the invention discloses a data transmission method and device of a terminal. The data transmission method comprises the following steps: the terminal interacts application data with a server through a first port by virtue of a first access node; in the situation that one port in a second port set is in an opening state, the port, which is in the opening state, in the second port set accesses one access node in a candidate access node set; based on a multipath TCP transmission protocol, the port in the opening state interacts application data with the server through the access node corresponding to the port in the opening state. According to the data transmission method, the purposes of fully utilizing network resources in aggregation or switching of data transmission links and improving the data transmission efficiency are realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal data transmission method and device. Background technique [0002] With the continuous popularization of WIFI networks, one or more wireless network APs are mostly deployed in public places such as airports, football fields, shopping malls or restaurants. However, in common technologies, most terminal devices can only access one AP at a time, and use this AP for data transmission. Therefore, it is difficult to realize rational utilization of network resources by terminal devices. The network signal provided by an AP is unstable, which can easily affect the efficiency of data transmission, making the data transmission between the application software and the network not smooth, and increasing the waiting time of users. [0003] On the one hand, in order to maintain the efficiency of data transmission, most mobile terminals currently adopt a solution of switching data ...
