Multi-state ground and space communication system and method thereof and communication platform server

A multi-state ground and space communication method, comprising the steps of:

• providing a plurality of communication devices, at least one fixed base station, at least one mobile communication vehicle, and at least one satellite, wherein the at least one fixed base station has a first communication platform server built therein, the at least one mobile communication vehicle has a second communication platform server built therein, and the at least one satellite has a third communication platform server built therein;
• receiving a status signal transmitted from an external device, the status signal being used to determine whether a current communication state is a first state period or a second state period;
• during the first state period, causing the plurality of communication devices to interconnect and communicate through the first communication platform server of the fixed base station;
• and
• during the second state period, causing the plurality of communication devices to selectively interconnect and communicate through the second communication platform server of the mobile communication vehicle or the third communication platform server of the satellite.

A communication platform server, comprising:

• a processor;
• a memory electrically connected to the processor;
• a communication unit for data exchange with external plurality of communication devices and with other communication platform servers;
• wherein the processor, based on instructions stored in the memory, is configured to:
• receive a status signal transmitted from an external device to determine whether it is a first state period or a second state period;
• during the first state period, when the communication platform server is configured in a fixed base station, allow external plurality of communication devices to interconnect and communicate through the communication platform server;
• during the second state period, when the communication platform server is configured in a mobile communication vehicle or a satellite, allow external plurality of communication devices to interconnect and communicate through the communication platform server;
• and
• set a synchronization frequency value for controlling a data synchronization frequency between the communication platform server and other communication platform servers.
