1. A method comprising:
- transmitting a message via a frequency of a frequency hopping sequence;
determining when the same frequency will reoccur in the frequency hopping sequence;
entering a sleep mode;
emerging from the sleep mode when the frequency at which the message was transmitted reoccurs in the frequency hopping sequence; and
monitoring for a response to the message via the frequency at which the message was transmitted when the frequency reoccurs in the frequency hopping sequence.

Abstract
Systems, apparatuses and methods for managing message communications in systems employing frequency hopping. One method according to the invention involves transmitting a message via a frequency of a frequency hopping sequence, and determining when the same frequency will reoccur in the frequency hopping sequence. Relevant portions of the device enter a sleep mode, and the device emerges from the sleep mode when the frequency at which the message was transmitted reoccurs in the frequency hopping sequence. The device monitors for a response to the message via the frequency at which the message was transmitted when the frequency reoccurs in the frequency hopping sequence.

14. An apparatus comprising:
-
a receiver; a transmitter configured to transmit a message via a frequency; a timer module configured to determine when the frequency will occur in a frequency hopping sequence; a sleep control module configured to cause at least the receiver to enter a sleep mode, and to cause the receiver to emerge from the sleep mode when the timer module indicates that the frequency has occurred in the frequency hopping sequence; and wherein the receiver is configured to monitor for a response to the message via the frequency at which the message was transmitted when the receiver has emerged from the sleep mode. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A system comprising:
-
at least one target device comprising a receive timing module configured to identify an active frequency in a shared frequency hopping sequence in which to monitor for incoming messages; at least one initiating device comprising; a receiver; a transmitter configured to transmit a response-evoking message to the at least one target device via a frequency; a timer module configured to determine when the frequency will occur in the shared frequency hopping sequence; a sleep control module configured to cause at least the receiver to enter a sleep mode, and to cause the receiver to emerge from the sleep mode when the timer module indicates that the frequency has occurred in the shared frequency hopping sequence; and wherein the receiver is configured to monitor for a response to the response-evoking message from the at least one target device via the frequency when the receiver has emerged from the sleep mode. - View Dependent Claims (22)
