DATA TRANSMISSION METHOD AND DEVICE

摘要

Embodiments of the present invention relate to the field of communications technologies, and disclose a data transmission method and a device, to reduce a quantity of TCP-layer ACK packets transmitted on a radio air interface link between a first device and a second device, thereby reducing consumption of radio air interface link resources and improving transmission efficiency of radio service data. A specific solution is as follows: obtaining, by a first device, a TCP-layer ACK; and intercepting the TCP-layer ACK if a TCP-layer data packet corresponding to the TCP-layer ACK is a TCP-layer data packet that is obtained by the first device after the first device parses a link layer data packet received through a radio air interface link by the first device, and the TCP-layer ACK satisfies a preset condition. The present invention is applied to a data packet transmission process based on a TCP connection.

主权项

1. A data transmission method, the method comprising:
obtaining, by a first device, a Transmission Control Protocol (TCP)-layer acknowledgement (ACK); and intercepting the TCP-layer ACK when a TCP-layer data packet corresponding to the TCP-layer ACK is a TCP-layer data packet that is obtained by the first device after the first device parses a link layer data packet received through a radio air interface link by the first device, and the TCP-layer ACK satisfies a preset condition, wherein the TCP-layer ACK satisfying the preset condition comprises:
the TCP-layer ACK does not satisfy a first filter criterion, and the TCP-layer ACK belongs to at least one of a first interception category or a second interception category.
