PROBLEM TO BE SOLVED: To distribute information data of a comparatively small data quantity and requiring immediacy such as a flash news efficiently in a PHS network. SOLUTION: Information data from a center 101 are stored in a cache of a base station 201 that relays a PHS slave set 11 and the center 101, and in the case that information data designated by an information data transfer request from each PHS slave set 11 in an area of the base station 201 are in existence in the base station 201, no communication is made with the center 101 but the base station 201 distributes the information data to the PHS slave set 11 immediately. Thus, in comparison with a conventional operation mode that communication with the center 101 is made every time the information data transfer request is issued from the PHS slave set 11, the effect of congestion in a speech transaction is relaxed and the system copes with requests from pluralities of slave sets 11 at the same time efficiently. |
