System and method for conserving energy in wireless devices
First Claim
Patent Images
1. A method of conserving energy in a wireless device, comprising:
- determining whether the device has ceased communication for a period of time;
selectively powering down components in the device when the device has ceased communication for the period of time;
receiving a paging message from a first communications network;
powering up the components in the device in response to receipt of the paging message;
registering, in response to receipt of the paging message, with a second communications network to receive a new network address; and
communicating, using the network address, via the second communications network, and not via the first communications network, in response to receipt of the paging message.

Abstract
A device conserves energy while engaging in wireless data communications. The device determines (705) whether it has ceased data communication for a first period of time. The device then selectively powers down (725) components in the device when the device has ceased communication for the first period of time.

5. A method of powering up components in a wireless device, comprising:
-
receiving a paging message at the device from a paging network, the device having components in a powered down state and the paging message instructing the device to power up components of the device;
powering up the components in response to the paging message;
registering, in response to receipt of the paging message, with another communications network to receive a new network address; and
communicating, using the network address, via the other communications network, and not via the paging network, in response to receipt of the paging message. - View Dependent Claims (6, 7, 8)

9. A computer-readable medium containing instructions for controlling at least one processor to perform a method that powers up components in a wireless device, the method comprising:
-
receiving a paging message at the device from a paging network, the device having components in a powered down state and the paging message instructing the device to power up components of the device;
powering up the components of the device in response to the paging message;
registering, in response to receipt of the paging message, with another communications network to receive a new network address; and
communicating, using the network address, via the other communications network, and not via the paging network, in response to receipt of the paging message. - View Dependent Claims (10, 11, 12)

13. A system for conserving energy in a wireless device comprising:
-
means for determining whether the wireless device has ceased communication for a period of time;
means for selectively powering down components in the device based on the determination;
means for receiving a paging message from a first communications network;
means for powering up the components in the device in response to receipt of the paging message;
means for registering, in response to receipt of the paging message, with a second communications network to receive a new network address; and
means for communicating, using the network address, via a second communications network, and not via the first communications network, in response to receipt of the paging message.

14. A wireless device comprising:
-
at least one transceiver; and
a processor configured to;
determine if the device has ceased communicating for a time period, instruct selected components of the device to power down when the device has ceased communicating for the time period, receive a paging message from a first communications network, power up components of the device in response to receipt of the paging message, register, in response to receipt of the paging message, with a second communications network to receive a new network address; and
communicate, using the network address, via the second communications network, and not via the first communications network, in response to receipt of the paging message.
