Provided are a synchronization method for distributed caching of data heat value, and a collaborative distribution caching method, device and system. The synchronization method includes: a first base station receiving a request that user equipment accesses a packet domain service; in response to the request for the packet domain service, if the first base station judges that the packet domain service is cached locally, then sending the packet domain service to the user equipment, and adding the current heat value of the packet domain service in a local caching content list of the first base station according to a pre-set function; and when the current heat value of the packet domain service has accumulated to a pre-set threshold value, the first base station sending the current heat value of the packet domain service to a heat information synchronization node in a wireless access network for synchronization, and clearing the current heat value of the first base station cached locally. The present invention solves the technical problem in the prior art that the data cached within the network cannot be shared, and the technical problem of saving the transmission bandwidth of the IUB interface. |
