Abstract

A mobile device is provisionable for service on a wireless wide area network (WWAN) operated by a licensed network operator and is further operable on at least one shorter-range, unlicensed wireless network (UWN). The mobile device stores applications that generate data when executed, including at least one application that generates data for communication over the WWAN. The mobile device executes a stored application and classifies data generated by the executed application into one of at least two categories based upon a domain of a target network to which the data is to be sent. A first category relates to data requiring communication at least partially over the WWAN and a second category relates to data not requiring communication over the WWAN. The mobile device establishes communication with a target device in the target network over at least the UWN based upon classification of the data generated by the executed application.
