| Abstract: | Both cellular communications(CelCom) and satellite communications(SatCom) have made brilliant performance in the last several decades. However,if they continue to develop individually,they can hardly comply with the current telecommunication service trend,shifting toward ubiquitous communication and interconnected everything. So,this trend will stimulate the cellular-satellite integration(CSI).This paper reviews the histories and statuses of CelCom and SatCom,analyzes the challenges of individual CelCom and SatCom and the benefits of CSI,and presents three evolution phases of CSI,ie.,federated network,hybrid network,and unified network.Finally,it discusses several related key techniques and future research topics. |
