Content distribution method and device as well as access network device

Abstract

Embodiments of the present invention relate to a content delivery method and apparatus, and an access network device. The method according to an embodiment of the present invention includes: receiving, by a cache server in an access network, a service request sent by a user equipment, where the service request contains an address of a content server in which service data requested by the user equipment is located; if the service data requested by the user equipment is stored, sending the stored service data to the user equipment through an access network device, modifying the address of the content server in the received service request into an address of the cache server in the access network, and sending the modified service request to a core network device; receiving the modified service request that is routed by the core network device to the cache server in the access network; and sending the stored service data to the cache server in the access network through the Internet, the core network device, and the access network device, and discarding, by the cache server in the access network, the service data. The technical solutions according to the embodiments of the present invention can enable the core network device to control and manage the service data requested by the user equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a content distribution method, device and access network equipment. Background technique [0002] Content Delivery Network (ContentDeliveryNetwork, CDN) is an application layer network architecture proposed to solve the current network congestion, broadband bottleneck and other problems. The content distribution network can quickly push the content accessed by users to the edge of the network, so that the user's request can be quickly responded to nearby, which not only greatly reduces the load of the network, but also reduces the probability of network congestion and shortens the request delay. To achieve this purpose, a cache (Cache) server may be used in the content distribution network. For example, a user equipment (User Equipment, UE) service request is first sent to a cache server in the access network, and if the service data requested by the user equipment is stored in...

Problems solved by technology

[0003] However, in the prior art, when the cache server in the access network stores the service data requested by the user equipment, the cache server in the access network provides the service data requested by the user equipment nearby through the access network, This makes it impossible for the core network equipment to control and manage the service data requested by the user equipment, and also unable to implement functions such as billing or monitoring for the user equipment
