Summary
In order to provide ubiquitous communication, 6G wireless networks will surely develop heterogeneous space-air-ground-sea integrated systems with multi-dimensional resources. In fact, satellite communications can complement terrestrial networks for service access for seamless service, UAV communications can relieve the terrestrial network congestion, etc.
However, to efficiently integrate various network segments with different scales and diverse radio access technologies in the space-air-ground-sea network, there exist many daunting challenges. Such challenges can be addressed by recent advances in SDN, AI, and network slicing technologies. To reach that goal, the space-air-ground-sea integrated network can have a layered heterogeneous architecture owing to SDN and network slicing, and AI can help make efficient decisions on network operation and service provisioning for seamless integration of such highly heterogeneous layers.
