Summary:PROBLEM TO BE SOLVED: To improve an information browsing system utilizing a portable radio terminal such that it can be utilized even in a location where a radio wave does not reach and information can be re-browsed without requiring re- communication. SOLUTION: At the time of browsing information, a decision is made at first whether the information to be browsed has been selected as one being displayed under Off-Line state (S4101). If it has been selected as one being displayed under Off-Line state (S4101: Yes), a decision is made whether data of that information exists in a cache memory or not (S4102). If communication is impossible (S4103: No), the control advances to (S4104). If communication is possible (S4103: Yes), update conditions of information at the host is detected and when information has been updated at the host, that information is displayed. Otherwise, information remaining in the cache memory is displayed (S4104, S4109).
