Abstract
A method and system is provided for initial network acquisition by a first device that is assisted by a second device. Rather than scanning one or more frequency bands to discover local wireless network information, the first device may send a request for local wireless network information over a secondary communication interface (i.e., a communication interface not associated with the wireless network for which information is sought). A second device that may have previously obtained the requested network information (e.g., it may have joined or be communicating through the wireless network) may respond by sending the requested wireless network information to the first device. Upon receiving the wireless network information via its secondary communication interface, the first device may use it to acquire a communication service from the wireless network over a primary communication interface (i.e., different from the secondary communication interface).
