10. The network device of claim 9, wherein the network device further comprises:
and the performance enhancement proxy PEP is used for judging whether the received service data is a 5G data message or not based on the throughput of the service data.
11. The network device of claim 9, wherein the network device further comprises:
an access request receiving module, configured to receive a user terminal access request;
the authentication module authenticates the user terminal;
the service data filtering module is used for filtering the received service data aiming at the authenticated user terminal so as to generate a 5G data message;
and the 5G data message sending module is used for sending the 5G data message.
12. The network device of claim 9, wherein the protocol conversion module is further configured to:
and performing interconversion on the satellite data message and the ground data message based on a performance enhancement proxy PEP of the 5G data service model.
13. The network device of claim 9, wherein the network device further comprises:
and the message copying and storing module is used for copying and storing the message after the protocol conversion into a high-speed cache and sending the message to the 5G core network through the non-3GPP access interworking function network element.
14. The network device of claim 13, wherein the network device further comprises:
and the safe connection module is used for connecting the control plane CP and the user plane UP of the 5G core network through an N2 interface and an N3 interface and providing safe connection for the user terminal.
15. The network device of claim 13, wherein the packet replication and storage module is further configured to:
retransmitting the copy of the data in the cache when the performance enhancing proxy PEP identifies a loss of the copy of the data.
16. The network device of claim 9, wherein the non-3GPP access interworking function network element is further configured to: AMF selection, encapsulation and decapsulation of packets, and packet inspection.
17. The network device of claim 9, wherein the network device is a gateway.
