Abstract

In a network comprising data devices having transmitters and receivers, a method and apparatus for temporally spreading network traffic associated with auto-on functionality of the data devices, the method comprising the steps of: activating receivers of the data devices prior to auto-on of the data devices in an unsynchronized manner; and receiving information on the receivers of the data devices prior to the auto-on of the data devices.

Claims

1. In a network comprising data devices having transmitters and receivers, a method of temporally spreading network traffic associated with auto-on functionality of said data devices comprising the steps of:

activating receivers of said data devices prior to auto-on of said data devices in an unsynchronized manner; and

receiving information on said receivers of said data devices prior to said auto-on of said data devices.

2. The method of claim 1, wherein said activating step includes setting a receiver-on timer on said data devices when said data devices are placed in a dormant state.

3. The method of claim 2, wherein said data devices are placed in a dormant state based on an auto off functionality on said data devices.

4. The method of claim 2, wherein forcing said data devices into an active state cancels said step of setting said receiver-on timer.

5. The method of claim 1, wherein user interfaces on said data devices are not updated prior to auto-on of said data devices.

6. The method of claim 1, wherein alerts from said data devices are not signaled to users prior to auto-on of said data devices.

7. In a network comprising data devices having transmitters and receivers, a method of temporally spreading network traffic associated with auto-on functionality of said data devices comprising the steps of:

activating receivers of said data devices after an auto-on of said data devices in an unsynchronized manner; and

receiving information on said receivers of said data devices after said activating step.

8. The method of claim 7, further comprising the step of setting a back-off timer on said data devices after an auto-on of said data devices and prior to said activating step, said activating step commencing at an expiry of said back-off timer.

9. The method of claim 7 further comprising the step of optionally terminating a dormant state on said data devices, whereby if said dormant state on said data devices is terminated, said receivers are activated immediately and said data devices move into an active state.

10. In a network comprising data devices having transmitters and receivers, a method of temporally spreading network traffic associated with auto-on functionality of said data devices comprising the steps of:

registering with a data server in said network after an auto-on of said data devices in an unsynchronized manner; and

receiving information from said data server after said registering step.

11. The method of claim 10, further comprising the step of setting a back-off timer on said data devices after an auto-on of said data devices and prior to said activating step, said registering step commencing at an expiry of said back-off timer.

12. The method of claim 10 further comprising the step of optionally terminating a dormant state on said data devices, whereby if said dormant state on said data devices is terminated, said data devices are registered immediately and said data devices move into an active state.

13. A data device having an auto-on function that temporally spreads network traffic associated with said auto-on function, said data device comprising:

a transmitter and receiver for communicating with a network;

a battery to power said data device;

a storage subsystem; and

a microprocessor interacting with said storage subsystem and said transmitter and receiver, said microprocessor including a timer for activating said receiver prior to or after activation of said auto-on function,

wherein said timer is set for a variable duration and said receiver is activated at the expiration of said timer to temporally spread network traffic.
