Abstract: In order to optimize the transmission control protocol (TCP) in the fifth generation of mobile communications system (5G), a survey on the optimization mechanism of TCP protocols in 5G multi-access networks is given. Firstly, the limitations and challenges of TCP protocols in wireless access networks are analyzed. Then, the TCP optimization schemes in wireless access networks are sorted out, which are mainly classified into single-path TCP optimization and multipath TCP optimization, simultaneously the comparative analysis of various optimization schemes is summarized. Finally, the development directions of TCP protocol optimization are presented.

Key words: multi-access networks, the fifth generation of mobile communications system, transmission control protocol, performance optimization
