Abstract: A wireless communication device (30) within a wireless communication system (10) includes a receiver (68) for receiving a message, a processor (78) coupled to the receiver (68) for processing the message, and a memory (80) coupled to the processor (78). The memory (80) includes a message memory (94) for storing the message and a location memory (96) for storing location information (100). The wireless communication device (30) further includes an operation mode management application (90) coupled to the processor (78). The operation mode management application (90) identifies at least one operation mode (112), and enables the operation mode (112) in response to a processor command (104) received from the processor (78).

Abstract: An acknowledge back portable selective call radio (10) for use in a selective call signal radio system (100) and method for determining selective call radio location (200-300), wherein the selective call radio (10) comprises a transceiver (14) for receiving selective call signals and transmitting acknowledge back signals, a processor (24) for monitoring and processing received selective call signals to monitor errors in the selective call signal, a global positioning system receiver (12) activated by the processor (24) when the number of errors exceeds a predetermined threshold, wherein the global positioning system receiver (12) receives satellite transmitted signals for triangulating the position of the selective call radio (10), and wherein the geographic location determined by the processor (24) is transmitted in the acknowledge back signal to the selective call signal transceiver station (110) where a transmission strategy is selected in accordance with the location of the selective call radio (10).
