Abstract

A connection establishment method includes a terminal device obtaining historical data of a multipath transmission control protocol (MPTCP) connection established between the terminal device and an application server. The historical data includes a data transmission delay of a transmission control protocol (TCP) connection corresponding to a Wi-Fi network and a data transmission delay of a TCP connection corresponding to a cellular network. The terminal device determines, based on the historical data, that the data transmission delay of the TCP connection corresponding to the cellular network is less than or equal to the data transmission delay of the TCP connection corresponding to the Wi-Fi network, and establishes a first TCP connection to the application server through an interface of the cellular network; and after the first TCP connection is successfully established, the terminal device establishes a second TCP connection to the application server through an interface of the Wi-Fi network.
