Data transmission method, base station and terminal

Abstract

Disclosed are a data transmission method, a base station, and a terminal. The base station comprises: a first receiving module, used for receiving a first instruction message sent by a terminal to be handed over from the base station to a target base station, the first instruction message being used for instructing the base station to send a to-be-pushed content block to the target base station; a determining module, used for determining the to-be-pushed content block according to the first instruction message received by the first receiving module; and a first sending module, used for sending to the target base station the to-be-pushed content block determined by the determining module. In the data transmission method, the base station and the terminal in embodiments of the present invention, when a terminal is handed over between base stations, an original base station actively pushes buffered content to a target base station, so that the data transmission delay caused by handovers between the base stations can be reduced, thereby improving user experience.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a data transmission method, a base station, and a terminal. Background technique [0002] With the rapid development of Internet technology and applications and the rapid growth of Internet users, the traditional Internet based on Transmission Control Protocol / Internet Protocol (TCP / IP, Transmission Control Protocol / Internet Protocol) has gradually exposed poor scalability and weak dynamic continuity. , low security controllability, high operating costs and other issues. For this reason, the Internet is gradually changing from host-centric to content-centric, and countries around the world have launched research on content-centric future networks, including North American Content-Centric Network (CCN, Content-Centric Network) / Named Data Network (NDN, Named-Data Networking), Data-Oriented Network Architecture (DONA, Data-Oriented Network ...

AI Technical Summary

Problems solved by technology

[0003] In the CCN architecture, when a mobile terminal switches between two base stations, it needs to resend an Interest packet requesting content to the target base station after the handover is completed, or send a message after the handover is completed to trigger the target base station to ask for data packets from the original base station. If the rate is low, it will cause a large delay in data transmission and affect the user experience.
