Abstract

The embodiments of the present application disclose a data transmission method and apparatus, which are used for realizing the transmission control of service data of a second terminal device by a first terminal device. The method of the embodiment of the present application includes: when a preset condition is satisfied, the first terminal device establishes a first transmission control protocol TCP connection with the application server, and establishes a second TCP connection with the application client of the second terminal device; the first terminal device The device receives the first service data sent by the application server through the first TCP connection; the first terminal device caches the first service data; the first terminal device sends the first service data to the The second terminal device sends the first service data.

Description

technical field [0001] The present application relates to communication technologies, and in particular, to a data transmission method and apparatus. Background technique [0002] Customer premise equipment (customer premise equipment, CPE) is a mobile signal access device that forwards received cellular signals as WiFi signals. For example, the CPE can convert the cellular signal of the 4G communication network or the 5G communication network into a WiFi signal, so as to support multiple terminal devices to connect to the WiFi signal to access the Internet. [0003] The CPE establishes a communication connection with the network by means of cellular signals, and the terminal device establishes a communication connection with the CPE by means of WiFi signals; then, the application client of the terminal device establishes a Transmission Control Protocol (TCP) with the application server through the CPE ) connection; the application server transmits the service data of the a...
