Method of enabling radio telecommunication apparatus to be used in a radio telecommunication system

摘要

An apparatus stores a plurality of mobile identification numbers. When a user selects at least one of the stored mobile identification numbers and the apparatus receives a mobile identification number transmitted from a base unit, the received mobile identification number is compared to each of the selected mobile identification number. When the user does not select any one of the stored mobile identification numbers and the apparatus receives a mobile identification number transmitted from the base unit, the received mobile identification number is compared to each of the stored mobile identification numbers. When the received mobile identification number coincides with one of the selected mobile identification number or one of the stored mobile identification numbers, the apparatus is enabled to communicate with the base unit.
