Abstract

Described is a method which includes receiving a selection of an application type, selecting a power management class as a function of the application type and adjusting resources of a mobile unit as a function the power management class.

Claims

1. A method, comprising:

registering an application with a power management class, the application identifying a first plurality of resources required by the application;

presenting a list of application types on a display of a mobile unit;

receiving a selection of the application type for the application;

selecting the power management class as a function of the application type, the power management class including the first plurality of resources of the mobile unit to be powered for the application type;

providing power to the first plurality of resources and powering down a second plurality of resources of the mobile unit until a further selection of a further application type is received, wherein receiving a selection of the application type for the application comprises receiving a plurality of application types associated with the application, and wherein selecting the power management class as a function of the application type comprises selecting the power management class that corresponds most closely to the application types.

2. The method according to claim 1, wherein the application type is associated with one or more applications executable by the mobile unit.

3. The method according to claim 1, wherein the selection of the application type is accomplished by one of a user, a server, a network device and a further mobile unit.

4. The method according to claim 1, wherein the selection of the application type is accomplished via a user interface.

5. The method according to claim 4, wherein the user interface is one of a button, a touchscreen and a code.

6. The method according to claim 1, wherein more than one application type is selected and the power management class is selected as a function of the more than one application types.

7. The method according to claim 1, wherein at least one of the first and the second plurality of resources of the mobile unit includes at least one of a peripheral, a function, a component, a mechanism and a setting.

8. A method, comprising:

presenting a list of application types on a display;

associating a plurality of application types from the list with an application, the application types each identifying a plurality of resources required by the application;

selecting the plurality of resources of a mobile unit which are utilized by the application loaded on the mobile unit;

defining a power-down order of the plurality of resources; and

registering the application for a power management class that most closely corresponds to the plurality of application types.

9. The method according to claim 8, further comprising:

associating one or more applications with an application type.

10. The method according to claim 8, wherein the plurality of resources of the mobile unit include at least one of a peripheral, a function, a component, a mechanism and a setting.

11. The method according to claim 8, wherein the application is registered for the power management class as a function of one of the resources selected and the power-down order.

12. The method according to claim 9, wherein the one or more applications are registered for the power management class as a function of the application type.
