  • Method and device for off hour over the air software programming of selective call receivers
    Patent number: 5726639
    Abstract: A selective call receiver (10) utilizes a method for performing over-the-air software programming when the selective call receiver (10) is on or switched off by a user. A first selective call signal is received and programming related information including an anticipated time of transmission of a second selective call signal is received. The selective call receiver (10) is prepared to receive the second selective call signal in response to the programming related information received, whereby the receiver circuitry (30) is energized at the anticipated time of transmission to receive the second selective call signal. The selective call receiver (10) is further switched on at the anticipated time of transmission of the second selective call signal, and the receiver circuitry (30) is energized to receive the second selective call signal when the user has switched off the selective call receiver (10) prior to the anticipated time.
