Abstract

A method and apparatus for managing power for devices that may be part of a group is provided herein. During operation a power-management device will transmit a power-management message to a device or group of devices. The message indicates a time period (keep-alive time) and critical services that are to be kept operating for the keep-alive time. In response, the device(s) that receive the message may transmit an information message indicating whether or not a device has enough power to run the services for the keep-alive time.

Claims

1. A method for managing device power, the method comprising the steps of:

identifying via logic circuitry, a device that is a member of a group of devices that are assigned to an incident scene;

identifying via the logic circuitry, critical applications on the device that need to be run by the group of devices at the incident scene;

identifying by the logic circuitry, a time period for the critical applications;

constructing, by the logic circuitry, a message comprising the critical applications and the time period; and

transmitting, via a transmitter, the message to the device, wherein the message causes the device to power on the identified critical applications on the device.

2. The method of claim 1 wherein the message also causes the device or group of devices to power off non-critical applications.

3. The method of claim 1 further comprising the steps of:

identifying non-critical applications; and

wherein the step of constructing the message further comprises the step of constructing the message comprising the non-critical applications; and

wherein the message further causes the device or group of devices to power off the identified non-critical applications.

4. The method of claim 1 further comprising the steps of:

receiving, via a receiver, a message from the device or group of devices, wherein the message comprises an indication of whether or not the device or group of devices can run the identified critical applications for the time period; and

a displaying via a graphical user interface, information on whether or not the device or group of devices can run the identified critical applications for the time period.

5. An apparatus comprising:

logic circuitry identifying a group of devices at assigned to an incident scene, identifying critical applications on the devices that need to be run by each device that is a member of the group of devices at the incident scene, identifying a time period for the critical applications, and constructing a message comprising the critical applications and the time period; and

a transmitter transmitting the message to the group of devices, wherein the message causes each device that is part of the group of device to power on the identified critical applications.

6. The apparatus of claim 5 wherein the message also causes the device or group of devices to power off non-critical applications.

7. The apparatus of claim 5 wherein:

the logic circuitry also identifies non-critical applications; and

the message further comprises the non-critical applications; and

wherein the message further causes the device or group of devices to power off the identified non-critical applications.

8. The apparatus of claim 5 further comprising:

a receiver receiving a message from the device or group of devices, wherein the message comprises an indication of whether or not the device or group of devices can run the identified critical applications for the time period; and

a graphical-user interface displaying information on whether or not the device or group of devices can run the identified critical applications for the time period.

9. An apparatus comprising:

a receiver within a device that is part of a group of devices assigned to an incident, the receiver receiving an over-the-air message comprising critical applications needed at an incident scene, and a time period;

logic circuitry activating the critical applications on the device identified in the message and inactivating non-critical applications.

10. The apparatus of claim 9 wherein the over-the-air message also comprises the non-critical applications.

11. The apparatus of claim 9 wherein the logic circuitry determines if the critical applications can be run for the time period identified in the message.

12. The apparatus of claim 11 further comprising:

a transmitter, transmitting a message indicating whether or not the critical applications can be run for the time period identified in the message.

13. The apparatus of claim 11 wherein the logic circuitry allows the powering on of non-critical applications only if the critical applications can be run for the time period specified in the message.
