The invention relates to the technical field of
satellite communication, in particular to a
satellite DVB and 5G different
system access network switching management method and
system, a user terminal sends a
wireless connection measurement report during 5G communication, a 5G
base station judges whether to switch a network according to the
wireless connection measurement report, and a switching request is sent to a gateway function conversion module through a newly added inter-
network interface. And the target
satellite beam serving
cell judges whether to accept or not, and after acceptance, the gateway function conversion module converts confirmation information and returns the confirmation information to the 5G
base station. Then, the target satellite beam serving
cell allocates resources, the 5G
base station sends an instruction to trigger the user terminal to switch and processes a data packet, the gateway function conversion module converts a
data format and then sends the data packet, the user terminal initiates access to complete switching, and efficient switching of different-
system networks is achieved.
