RADIO TELECOMMUNICATION APPARATUS

摘要

Radio communication apparatus stores at least one authentication number and at least one system identification number. Each of the authentication number corresponds to one of the stored system identification number. When the apparatus receives a system identification number transmitted from a base station, the apparatus compares the received system identification number with each of the the stored system identification number . When the received system identification number corresponds to one the stored system identification number, one of the stored authentication number corresponding to one of the stored received system identification number is adopted.
