Abstract
A method for registration of a portable unit that may be utilized in a communication system that comprises a network controller, having a data base for storing portable identification numbers, a base station, and a portable unit, wherein a subscriber communicates to the network controller a first information set which comprises subscriber qualifying information, the portable identification number, and a key code that has been entered into the portable, and wherein the subscriber has entered a link identification number for over-the-air registration into a memory within the portable unit. The registration method comprises the following steps. The portable unit sends the base station a request for registration. The request for registration comprises the link identification number for over-the-air registration and the portable identification number. The base station receives the request for registration from the portable unit, and sends to the network controller a notice of the request for registration and the portable identification number. The network controller receives the notice of the request for registration from the base station, and determines whether the portable identification number is in the network controller data base, and whether the subscriber has been approved for registration. The network controller then sends to the portable unit, through the base station, a registration information signal if the network controller determines that the portable identification number for over-the-air registration is in the network controller data base, and that the subscriber has been approved for registration, the registration information signal comprising an encrypted secret subscriber identification number that has been encrypted with the key code, and an unencrypted link identification number for base station access.
