Query: Mobile Converged Networks: Framework, Optimization and Challenges   In this paper, a new framework of mobile converged networks is proposed for
flexible resource optimization over multi-tier wireless heterogeneous networks.
Design principles and advantages of this new framework of mobile converged
networks are discussed. Moreover, mobile converged network models based on
interference coordination and energy efficiency are presented and the
corresponding optimization algorithms are developed. Furthermore, future
challenges of mobile converged networks are identified to promote the study in
modeling and performance analysis of mobile converged networks.
