In order under the prerequisite of wananty costs, reduce the access time delay of user, a kind of method that the embodiment of the present invention provides content to store, the method is applied in content storage system, and as shown in Figure 1, the method comprises:
101, the visitation frequency of data to be visited in measurement period is determined, the data that the access request that data to be visited send for base station is asked.
It should be noted that, the access request that content storage system can send according to base station determines the unique identification information of user, and then according to the unique identification information of user, utilize the local User Priority list stored, or obtain from the base station proposing access request, or obtain from upper level content storage system, or from the User Priority list that radio communication core net obtains, the user priority information of record access request.Content storage system can add up the frequency that each data to be visited are accessed by all users and the frequency of being accessed by high-priority users in cycle t, and high-priority users is the user of User Priority higher than the second preset value.
Measurement period in this step is N number of cycle t, cycle t determines according to the behavioural habits of user, the data variation of user's access is more frequent, it is less that cycle t is arranged, such as, when user accesses data change is more frequent, cycle t 5 minutes can be set to, when user accesses data change is slower, cycle t 1 hour can be set to.
N be default be more than or equal to 1 integer, N is needed to be set to a comparatively suitable value according to the actual conditions of cycle t and Current Content storage system, make the visitation frequency determined both can reflect user's request in time, the access hit rate of the data of storage can be improved again.
Wherein, in visitation frequency=mono-measurement period, data to be visited are treated by the frequency+the first preset value * that all users access the frequency that in same measurement period, visit data is accessed by high-priority users, first preset value be more than or equal to 0 rational, the setting of the first preset value is relevant with the selection of high-priority users, when wishing the data access latencies of high-priority users apparently higher than other users, it is slightly large that the first preset value can be arranged; When not needing the experience excessively improving high-priority users in data storage, the first preset value can be set to 0.
102, the service priority of business and visitation frequency belonging to data to be visited, determine the weighting frequency of data to be visited.
