COMMUNICATION SYSTEM, MOBILE TERMINAL, AND COMMUNICATION METHOD

PROBLEM TO BE SOLVED: To provide a communication system, a mobile terminal, and a communication method in which reduction in data packet transmission delay or network traffic can be attained. SOLUTION: The present invention relates to a communication system for a mobile terminal utilizing a plurality of communication media, wherein middle layers 54A, 54B are formed between session layers (applications 51A, 51B) and transport layers (TCP 52A, 52B) in an OSI basic reference model and in the middle layers 54A, 54B, there are packaged a first protocol including a function similar to that of a protocol packaged in a network layer in the OSI basic reference model and a second protocol including a function similar to that of a protocol packaged in the transport layer in the OSI basic reference model.
