Abstract

A mobile communication terminal performs: registering a length of time starting at a time when an identifier of a base station is detected by a first communication unit, the identifier being transmitted by the base station accommodated in a first communication network, and ending at a time when the first communication unit accesses an access point accommodated in a second communication network in association with the identifier, the access point having an accessible range smaller than that of an accessible range of the base station; and starting, at the second first communication unit, a search for access information transmitted by the access point when a reference time determined based on a length of time associated with the registered identifier has passed a time when the identifier is detected, in a case where the identifier detected by the first communication unit is stored.
