A kind of satellite mobile communication system TtT communication means

The present invention discloses a kind of satellite mobile communication system terminal traffic data without core net circulation directly in the method for Onboard switching (TtT communication), is related to the technology in terms of the connection of field of satellite mobile communication wireless heterogeneous networks is established with resource allocation.Various signalings and the process of data transmission in the Network Element Function design and business foundation and resource allocation process of system is described in detail in it.It mainly resource allocation process is fused to wireless heterogeneous networks in a kind of satellite mobile communication system connects method in establishment process by designing, solve to influence much higher than the propagation delay of the satellite mobile communication system on ground to the high voice service bring of requirement of real-time.Present invention can apply in satellite mobile communication system scene, can efficiently reduce the negative effect for defending communication channel long delay to voice service user experience, hence it is evident that improve user's impression.
