Abstract: A user accesses a search server from a cellular telephone, and enters on a search page a numeric string obtained by numerical conversion of a keyword related to a desired site in accordance with an assignment relationship between characters and numerical keys. The search server searches a database by using as a key the numeric string sent thereto or a character string obtained by character conversion of the numeric string in accordance with the above-mentioned assignment relationship to retrieve candidates for a connection destination site, thereby sending back a reply to the cellular telephone of the user. The user selects a desired connection destination site from among the candidates to send back a reply to the search server. The search server responds to the cellular telephone by indicating a site address previously associated with the determined connection destination site as an access request destination. The cellular telephone accesses the connection destination site indicated by the received response.
