In a wireless communication system, time point information is transmitted from a second wireless base station. The time point information indicates a time point at which service information is transmitted from the second wireless base station. Moreover, at the time point indicated by the time point information, the service information is transmitted from the second wireless base station. On the wireless terminal side, firstly, the time point information is obtained in a first non-communication period in which communication with the first wireless base station is temporarily stopped. Then, the service information is obtained in a second non-communication period which is ensured in accordance with the time point indicated by the time point information.
