Method and apparatus for optimizing hybrid communication

An apparatus for optimizing communication in a hybrid communication network including heterogenous networks, the apparatus comprising:

• an input port configured to receive inputs from an external device;
• a memory configured to store data and information;
• a main processor configured to control overall operations;
• a communication circuit including a satellite communication processor and a cellular communication processor, configured to obtain service requirement information for supporting communication between a service server and a user equipment (UE) through a hybrid communication network including a satellite network and a cellular network, where the service requirement information is information on service requirements related to the service server and the service requirement information includes a guaranteed network speed and an allowed latency;
• and
• a sub-flow control processor configured to control (adjusting) a number of sub-flows of the hybrid communication network based on the service requirement information and service performance information, where the service performance information includes a current network speed and a current latency in communication between the service server and the UE.
