Abstract
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.
