Abstract

A mobile computing device that supports cost-aware application components for operation over a metered network. A current basis for computing usage charges over one or more networks may be made available to the cost-aware application components through an application programming interface supported by an operating system service. That service may receive a policy for charging for data usage over a network and may also obtain information defining data usage for the mobile computing device. Based on this information, the service may determine a current basis for charging for data usage. With this information, the application component can determine a manner for executing network operations that involve data transmission over the network, such as deferring the operation or selecting an alternative network.

Claims

1. A method of operating a computing device, the method comprising:

with at least one processor;

for each network of at least one network, receiving information defining a policy for charging for data usage;

for each network, determining data usage on the network;

determining for an identified network, based on the policy and data usage, a current basis for usage charges on the identified network; and

providing to a user mode component executing on the computing device current network information comprising at least the current basis for usage charges on the identified network.

2. The method of claim 1, further comprising:

selecting, by the user mode component, an action based on the current basis for computing usage charges.

3. The method of claim 2, wherein:

the selected action comprises deferring a network operation.

4. The method of claim 2, wherein:

the at least one network comprises a plurality of networks; and

the selected action comprises performing a network operation over an alternative network of the plurality of networks.

5. The method of claim 1, wherein:

the user mode component comprises one of an application or an operating system service.

6. The method of claim 1, wherein:

receiving the information defining the charging policy for a network comprises receiving the information from an operator of the network.

7. The method of claim 6, wherein:

determining for an identified network data usage on the network comprises tracking, within a network interface on the computing device, data exchanged over the network.

8. At least one computer-readable storage medium comprising computer executable instructions that, when executed, implement a user-mode component that performs an operation based on data obtained over a network, the component comprising computer-executable instructions for:

obtaining through an application programming interface current network information for an identified network, the current network information comprising at least a current basis for usage charges on the identified network;

determining a characteristic of execution of the operation based on the current network information; and

selectively executing the operation with the determined characteristic.

9. The computer-readable storage medium of claim 8, wherein:

the current network information comprises at least one flag indicating a current state of the network connection, the current state indicating at least one of an over-cap or throttled state.

10. The computer-readable storage medium of claim 8, wherein:

the current basis for usage charges comprises a value from an enumerated set of charging policies, the enumerated set comprising values indicating unrestricted usage, fixed-price usage up to a cap and a charge per unit of data.

11. The computer-readable storage medium of claim 8, wherein:

the current basis for usage charges comprises an indication derived by applying a policy for charging for data usage to a determined amount of network usage.

12. The computer-readable storage medium of claim 8, wherein:

determining a characteristic of execution of the operation comprises identifying a later time when charges for data usage are lower than at a current time; and

selectively executing the operation comprises deferring execution of the operation until the later time.

13. The computer-readable storage medium of claim 8, wherein:

determining a characteristic of execution of the operation comprises identifying a an alternative network for which charges for data usage are lower than for the identified network;

selectively executing the operation comprises executing the operation over the alternative network.

14. The computer-readable storage medium of claim 8, wherein:

the computer-executable instructions for determining a characteristic of execution of the operation comprises;

a first set of instructions that are conditionally executed when current network information indicates that usage on the identified network is over a cap for the network;

a second set of instructions that are conditionally executed when current network information indicates that usage on the identified network is below a cap for the network.

15. The computer-readable storage medium of claim 14, wherein:

the user mode component comprises a component for updating software; and

the first set of instructions comprises instructions for deferring execution of a download until a free network is detected.

16. A system, the system comprising:

a wireless network for providing data services to a plurality of mobile computing devices; and

a server for providing to each of the plurality of mobile computing devices charging information comprising;

a value defining a policy for charging for data usage; and

a value indicating a state of data usage by the mobile computing device.

17. The system of claim 16, wherein:

the charging information further comprises at least one flag indicating a state of the mobile computing devices relative to at least one threshold for data usage.

18. The system of claim 16, wherein:

the charging information further comprises;

data usage within a current billing cycle; and

an end date of the current billing cycle.

19. The system of claim 18, wherein:

the charging information further comprises;

a time stamp.

20. The system of claim 18, further comprising:

a mobile computing device comprising an operating system component that receives the charging information and provides current network information through an application programming interface, the current network information comprising at least a current basis for computing usage charges for data transmission on the wireless network.
