<p>A portable terminal capable of reliably carrying out reselection even though power consumption is reduced and thereby increasing the chance to wait for connection to the upper-layer communication system so as to realize a long-time communication system so as to realize a long-time standby and to enable an increase of the traffic efficiency. A portable terminal communication method and a wireless network system are also disclosed. The portable terminal (10) has control section (8) which acquires neighboring base station information from the base station with which the terminal (10) is communicating through a communication section (1), monitors the signal intensity in the communication system which the terminal (10) is using, carries out hand-off from the communication system being used to another communication system included in the neighboring base station information if the present signal intensity decreases below a predetermined one, releases the session of the communication system being used, tries to capture the another communication system, selects a first mode to inhibit reselection if information representing the another communication system different from the one being used, is included in the neighboring base station information, and executes reselection to select a second mode not inhibiting reselection if the information is not included in the neighboring base station information.</p> |
