Embodiment Construction

[0040]In the embodiment of the present invention, a UMTS network is taken as an example for description. In this embodiment, the radio access network RAN ​​is composed of NodeB and RNC. Among them, the cache Cache used to store hot content is distributed and deployed in multiple NodeBs under the jurisdiction of the RNC, and the NodeB and RNC can cooperate with the Cache, and the popularity information of the content accessed by the user is uniformly maintained by the popularity information synchronization node. The popularity information synchronization node may be a central control base station or an RNC. In this embodiment, the popularity information synchronization node is RNC.

[0041] Create new physical links between NodeBs subordinate to RNC and add corresponding signaling to form a network including RNC and subordinate NodeBs, which are used to exchange cached files and their storage locations on the UTRAN side. The connection between NodeBs can be an IP connection, ...

Abstract

The invention provides a method, device and system for synchronizing a cached data heat value, and a distributed caching method, wherein the synchronizing method comprises the following steps that: a first base station receives a request of user equipment to access a packet domain service; in response to the request for the packet domain service, the first base station sends the packet domain service to the user equipment if determining that the packet domain service is locally cached, and the current heat value of the packet domain service is added to the local caching content list of the first base station based on a preset function; and when the current heat value of the packet domain service is accumulated to a preset threshold, the first base station sends the current heat value of the packet domain service to a heat information synchronizing node in a wireless access network for synchronization, and resets the current heat value locally cached by the first base station. The method provided by the invention solves the technical problem of incapability of realizing within-network cached data sharing in the prior art, and can also avoid the technical problem of the transmission bandwidth of an IUB interface.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a method for synchronizing the heat value of distributed cached data, a method, a device and a system for cooperatively distributed caching of cached data. Background technique [0002] In a Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System), a cache (Cache) may be deployed in a Radio Network Controller (RNC, Radio Network Controller) or in a base station (Node B). [0003] If it is deployed in the RNC, it is necessary to deploy local storage media and heat information on the RNC. At the same time, the RNC parses the application layer data packets and locally caches the content that meets the cache decision conditions. The RNC is responsible for maintaining the cached content and the heat that has not reached the threshold. content, but resource popularity information may also be cached later. The capacity of ...
