Abstract

The invention provides a CDN content distribution network redirection method and system, relates to the technical field of communication, and is used for solving the problem that an edge service nodecannot be flexibly redirected in the prior art. The method comprises the steps that a first edge service node confirms that a base station connected with a target terminal is changed, generates CDN redirection information and sends the CDN redirection information to a scheduling control network element; the scheduling control network element receives the CDN redirection information sent by the first edge service node and determines an available second edge service node; then, the scheduling control network element sends a second service request of a target terminal to a second edge service node, and the second edge service node provides CDN service for the target terminal; and the scheduling control network element sends the access address information of the second edge service node to thetarget terminal. The method and system are applicable to a scenario in which a terminal switches a base station.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a CDN redirection method and system. Background technique [0002] The popularization of 5G technology will enable high-traffic mobile applications and gradually become popular, while the influx of terminal equipment and service requests will inevitably cause network congestion. For a long time, content delivery network (content delivery network, CDN) technology has been used to alleviate the network congestion problem. CDN technology refers to the content distribution network built on the network, relying on the edge servers deployed in various places, through the load balancing, content distribution, scheduling and other functions of the central platform, users can obtain the required content nearby and improve the overall distribution efficiency. Reduce network latency and save bandwidth resources. [0003] The current CDN is not enough to meet the application...
