A data-cache apparatus for providing a data-cache function to a radio communications system is disclosed. The data-cache apparatus includes a data distinguishing unit ( 310 ) to distinguish an attribute of data requested by a mobile station, a cache memory ( 340 ) that temporarily stores data provided to a mobile station, and a data request processing unit ( 320 and 330 ) to acquire requested data from the cache memory or an external server based on a result of distinction carried out by the data distinguishing unit. The data request processing unit performs operations of searching for the requested data in the cache memory, and storing the acquired data in the cache memory.
