Cached content hitting method and communication system

Abstract

The embodiment of the invention discloses a cached content hitting method and a communication system. The cached content hitting method and the communication system are used for guaranteeing that a billing and monitoring device monitors and billing content accessed by a user. The method comprises the steps that an edge caching device receives and stores a content request message, carrying content identification, from access network equipment; the edge caching device seeks the content corresponding to the content identification in local cached content and sends the content to the access network equipment when it is determined that the content corresponding to the content identification is stored; the edge caching device adds content hitting identification into the content request message and then forwards the content request message to a core caching device; the core caching device sends a response message carrying the content to a cache control device through the billing and monitoring device, wherein the response message carries the content hitting identification; the cache control device discards the content in the response message according to the content hitting identification. According to the cached content hitting method and the communication system, it can be guaranteed that the billing and monitoring device monitors and bills the content accessed by the user.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a cache content matching method and a communication system. Background technique [0002] In the existing network architecture, billing monitoring equipment is set between the Internet and the wireless access network. to the user. In this way, it can be ensured that the billing monitoring device can monitor the Internet content accessed by the user, so as to perform billing according to the content. [0003] In order to improve the user's access experience and save the investment in network equipment caused by repeated content transmission, an Internet caching device is generally installed between the billing monitoring device and the Internet to cache the content that users repeatedly access to the Internet. When the Internet cache device stores the Internet content to be accessed by the user, the Internet cache device sends the content to the charging listening device, and...

Problems solved by technology

[0005] However, because this part of the duplicate content is directly cached and returned to the user by the wireless access network when the user accesses it, without passing through the billing monitoring device, the billing monitoring device will cause the wrong charging of the user's traffic, which will affect the traffic revenue of the operator. And avoid the lawful interception of this part of the content
