Problems solved by technology

However, the existing CDN technology is to redirect to the cache server before the connection between the user equipment and the content server is established, that is to say, the network completes the redirection before knowing what content the terminal wants to obtain, which will lead to DNS redirection may be inaccurate when the amount of content stored in the cache server is not large enough

Abstract

This application provides a redirection method, control plane network element and aggregate user plane network element, which can accurately locate the cache server and aggregate user plane network element after obtaining the content information requested by the terminal device, and match parameters according to the service flow Match the service flow, and then, you can quickly obtain the content requested by the terminal device. The method includes: a control plane network element acquires a content transmission request sent by a content server; the control plane network element determines, according to the content transmission request, a cache node for storing content to be transmitted and an aggregation user plane network element associated with the cache node; The control plane network element sends a service flow matching parameter to the aggregation user plane network element, and the service flow matching parameter is used to match the service flow of the content to be transmitted, and determine a connection for transmitting the matched service flow.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a redirection method, a control plane network element, an aggregation user plane network element, a content server and a terminal device. Background technique [0002] With the development of Internet technology, user equipment (User Equipment, UE) can access network resources all over the world. However, long-distance network resource transmission results in long transmission delay and occupies a lot of network bandwidth resources. For example, Facebook’s video server is deployed in the United States. If Chinese users want to access the video server, the video content must be transmitted between the United States and China, so the video content is very far away from the user, which not only has a long transmission delay , It also takes up a lot of network bandwidth resources. [0003] A Content Delivery Network (CDN) is a technology that enables content (suc...
