Abstract

An extensible wireless framework for connecting to a wireless network is provided. The extensible wireless framework includes a network roaming service with a registration component and a network service component. The registration component registers extensible service modules and extensible drivers for providing non-standard (i.e., extensible) capabilities to the wireless network. The extensible service module provides a service not provided by a native component of the extensible wireless framework, and the extensible driver may implement a media access control sub-layer of a wireless network protocol and provide a media access control interface. The network service component identifies available wireless networks, selects to join the wireless network when available, requests the extensible driver for the wireless network via its media access control interface to connect to the selected network, and notifies the extensible service module to provide services to the extensible driver.

Claims
