ABSTRACT:
A wireless communications device (200) that has a battery power source (330) and that has a power source monitor (332) that produces a low energy notification upon determination of a low energy condition within the battery. The wireless communications device further has a notification list specifying at least one other communications device to receive the low energy notification message. The wireless communications device (200) also has a notification transmitter (316, 314, 304) for transmitting the low energy notification message to communications devices held by other users (504, 506, 508, 512) that are in the list. The low energy notification message has at least one destination address to which the low energy notification message is to be sent. The wireless communications device (200) further serves as a proxy or surrogate relay for other wireless communications devices (200) to provide a robust communications system.
