Abstract

A portable radio device (106) has a first operational mode and a second operational mode, and includes a receiver (314), a controller (315), and a mode control device (350). The receiver (314) receives an indexed information message. The controller (315) stores an authorized information field list and is coupled to the receiver (314). The controller (315) decodes the indexed information message, generates an index portion of the decoded indexed information message, and generates a mode control schedule determined by the index portion and the authorized information field list. The mode control device (350) is coupled to the controller (315) for controlling the first and second modes of the portable radio device according to the mode control schedule.
