The invention discloses a method and system for searching for online users. A storage unit is set for an SP, and adapted to store the basic information and status information of users. Thus, after receiving an online user search request that carries search conditions from an XDMC, the SP can determine online users meeting the search conditions according to the basic information and status information of users in the storage unit, and send search results that carry the basic information of the online users to the XDMC. The storage unit may be set for the SP or shared by the SP and the XDMS. Because the storage unit set for the SP stores the basic information and status information of users, the SP does not need to interact with the PS to obtain the status information of users and or interact with the XDMS to obtain the basic information of users after receiving an online user search request from the XDMC. This greatly reduces the frequency of communications between communication entities and the communication burden of each communication entity, and increases the response speed of the XDMC.

The invention provides an establishment method, method and system for a time series data combined query cache. Relative to a general key / value cache, the time series data combined query cache established by the establishment method, method and system comprises a storage unit of time series data and a storage unit of query results, wherein the storage unit of the time series data comprises a time data set file and a query time range file, and the storage unit of the query results comprises a unique identification file and a query time range file. The combined query cache has two remarkable improvements regarding to the processing of the time series data: firstly, the hit rate of the cache is remarkably improved, and due to the fact that the combined query cache can identify hit of a part of time intervals, query pressure of a back end storage system is obviously reduced; secondly, storage capacity of a caching system is obviously reduced, and data redundancy in storage is completely eliminated due to the facts that the storage particle size of data in the combined query cache is small and metadata information is rich.
