Abstract: An indicator for a device may provide an indication that a threshold associated with a budget for a network resource has or will be reached. When a user requests a network operation that will consume the network resource, an amount of the network resource to be consumed by the operation is predicted, if possible. If the prior use of the network resource and the amount to be used to complete the network operation exceeds a threshold the user may be warned and given an opportunity to cancel the operation or adjust the way in which the operation will be performed. If the amount of network resource a network operation will consume is unknown, a rate of use of the network resource is determined and a time until the budget is reached is estimated.

An administrative tool is provided for managing network resources and setting budgets for resource consumption by users, devices, or applications.

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.
