METHOD AND APPARATUS FOR SYNCHRONIZING POPULARITY VALUE OF CACHE DATA AND METHOD, APPARATUS, AND SYSTEM FOR DISTRIBUTED CACHING

摘要

Embodiments of the present invention include a method for synchronizing a popularity value of distributed cache data, a method, an apparatus, and a system for cooperative and distributed caching. The synchronizing method includes: receiving, by a first base station, a request for accessing a packet domain service sent by a user equipment; if the first base station determines that the packet domain service is locally cached, sending the packet domain service to the user equipment and incrementing a current popularity value of the packet domain service in a list of locally cached content of the first base station according to a preset function; and sending, when the current popularity value of the packet domain service is accumulated to a preset threshold, the current popularity value to a popularity information synchronizing node for synchronization, and clearing the current popularity value locally cached. The present invention saves a transmission bandwidth of an IUB interface.

1. A method for synchronizing a popularity value of distributed cache data, wherein the method is applied to a radio access network, the radio access network comprises a popularity information synchronizing node and base stations managed by the popularity information synchronizing node, a cache configured to store hot content is deployed in a distributed manner in the base stations, and the method comprising:
receiving, by a first base station of the radio access network, a request for accessing a packet domain service sent by a user equipment; responding to the packet domain service request, and if the first base station determines that the packet domain service is locally cached, sending the packet domain service to the user equipment and incrementing a current popularity value of the packet domain service in a list of locally cached content of the first base station according to a preset function; and sending, by the first base station when the current popularity value of the packet domain service is accumulated to a preset threshold, the current popularity value of the packet domain service to the popularity information synchronizing node for synchronization, and clearing the current popularity value locally cached by the first base station.
