With the continuous development of information and communication technology

mobile communication network gradually evolves to 5 G. 5 G SA is a new network architecture based on service interface.Signaling messages based on HTTP2.0 protocol are used among functional entities. How to build a signaling network becomes the key to the planning and construction of 5 G core network. By analyzing the characteristics of 5 G signaling

this paper puts forward a feasible scheme of signaling networking

which provides suggestions and reference for 5 G signaling networking.
