Abstract

Concepts and technologies are described herein for a network-assisted device-based radio access control. According to one aspect disclosed herein, a mobile device selects one or more radio access networks (“RANs”) to connect to, based upon network conditions, policies, user profiles, local device information, and/or other information. The mobile device can receive network load information from multiple RANs. The mobile device can also receive one or more policies from a radio access technology (“RAT”) selection system. The mobile device can also obtain local device information such as, but not limited to, mobility state information, performance measurement information, battery utilization information, channel quality information, applications, and/or a user override selection.
