Abstract
An identification (ID) code (204) in a memory slot (203) within a communication unit (200) is programmable only through a received RF message and a valid trigger for programming the memory slot (203). No other connection to the radio, such as a standard programming port (206), is capable of being used to program the memory slot (203). An ID code (204), such as a security ID, is programmed via an RF message. The ID code (204) is a special code known to a communication system. No request for a communication resource is granted to a communication unit (200) that does not have the ID code (204), thereby keeping unauthorized users from gaining access to the communication system.
