Abstract

A heterogeneous network which supports multiple communication technologies (e.g., communication in accordance with multiple air interface standards) in a unified architecture can provide near-term solutions to capacity problems. Specifically, in one embodiment, a heterogeneous network that includes both macro-base cells and pico cells and that incorporates longer range wireless air interfaces (e.g., second, third, or fourth generation wireless air interface standards) and shorter range wireless air interfaces (e.g., Wi-Fi) can be provided. Such a heterogeneous network can include the coordination of security, quality of service, assessment of mobility of user equipment, authentication, provisioning systems, and location information.
