As the fifth-generation (5G) mobile com-munication network may not meet the requirements of emerging technologies and applications,includ-ing ubiquitous coverage,industrial internet of things(IIoT),ubiquitous artificial intelligence (AI),digital twins (DT),etc.,this paper aims to explore a novel space-air-ground integrated network (SAGIN) archi-tecture to support these new requirements for the sixth-generation (6G) mobile communication network in a flexible,low-latency and efficient manner.Specif-ically,we first review the evolution of the mobile com-munication network,followed by the application and technology requirements of 6G.Then the current 5G non-terrestrial network (NTN) architecture in support-ing the new requirements is deeply analyzed.After that,we proposes a new flexible,low-latency and flat SAGIN architecture,and presents corresponding use cases.Finally,the future research directions are dis-cussed.
