In this paper, by exploiting the availability of multiple cellular Radio Access Networks (RANs), the authors propose a novel two-level cooperative access network framework for superior energy efficiency. Geographically co-located RANs mutually cooperate each other through the combined use of Base Transceiver Station (BTS) level intra-network cooperation and RAN level internetwork cooperation. By jointly applying the two types of cooperation, BTSs within individual RAN as well as BTSs of several RANs communicate and intelligently cooperate for dynamically minimizing the number of active BTSs and thus reduce energy utilization at the access network level.
