Abstract

Concepts and technologies are described herein for a hybrid network-based and device-based intelligent radio access control. According to one aspect disclosed herein, a radio access technology (“RAT”) selection system and a mobile device cooperate to enable an intelligent multi-radio access control that can select a RAT that is best-suited for the mobile device. The RAT selection system can select networks based upon network conditions, policies, user profiles, applications, and/or other information, and provide a list of the networks to the mobile device. The mobile device can utilize local device information to select a network from the list. In this manner, the RAT selection system and the mobile device can cooperate to steer traffic to various networks operating in accordance with different RATs to improve user experience, especially in network traffic congested areas, and to efficiently leverage network resources for mobile telecommunications and WI-FI networks.
