Abstract
A client apparatus (20) requesting acquirement of various information stored in an information source server (21) receives, through a GW apparatus (23), the information from the information source server (21) transiently stored in a cache memory (25) by an agent program (28) of the GW apparatus (23), in accordance with profile information of the client apparatus (20), preference information of its user and communication attribute information of a data communication network (22, 24), while effectively using the data communication network (22, 24). The client apparatus (20) stores the reception information from the GW apparatus (23) in a cache memory (26), in accordance with attribute information (27), and re-configures the information accumulated in the cache memory (26) for each access by considering the relation to the stored information. Thus, it is possible to provide an information providing system and an information providing method, which can attain the effective communication in conjunction with the acquirement of the information provided by the information source server (21) to the client apparatus (20) having a low process ability, and a client apparatus (20) that can effectively acquire the various information provided by the information source server (21) even in the case of the low process ability.
