In order to meet different data rate and timeliness requirements of different services in aeronautical network communications based on frequency and time-hopping mechanism, a hybrid media access control protocol based on pre-allocation of transmission time slots and immediate access is proposed. It is based on network capacity simulation analysis of burst service frames, channel immediately access capability is reserved for high-priority service frames, and time slot pre-allocation strategies and network access permissions are designed for middle- and low-priority service frames. Time sensitive demand of high-priority service frames is guaranteed, and transmission of middle- and low-priority service frames to the greatest extent is ensured at the same time. The simulation results verify the effectiveness of the protocol.
