  The radio terminals 2a to 2c detect the notification signal transmitted from the radio base station 1 and confirm the contents (steps S418 to S420). More specifically, the radio terminals 2a to 2c read the terminal identification information stored in the Vender Specific area provided in the notification signal, and confirm whether it matches the terminal identification information of the own apparatus. Here, since the terminal identification information included in the broadcast signal matches the terminal identification information for identifying the wireless terminal 2b, the wireless terminal 2b starts processing for connecting to the wireless base station 1. On the other hand, since the terminal identification information included in the broadcast signal does not match the terminal identification information for identifying the wireless terminal 2a or the terminal identification information for identifying the wireless terminal 2c, the wireless terminal 2a and the wireless terminal 2c The process for connecting is not executed (no process is executed).
