5G SA Method and system for data communication applying network slicing for each 5G SA service content and telecommunication terminal device therefor

摘要

The present invention relates to a data communication method and system to which network slicing is applied for each 5G SA service content, and a communication terminal therefor, wherein the data communication method to which network slicing is applied for each 5G SA service content is formed for each 5G SA (Stand Alone) service content A method of transmitting data through a network slicing path that becomes a network slicing path, comprising: a first step in which a network slicing policy in which a network slice is made based on content executed by an HTTP message of a terminal (UE) is registered in a Policy Control Function (PCF); When information of the terminal is registered in the core network (CN), the core network transmits Configured Network Slice Selection Assistance Information (NSSAI) and network slicing policy information to the terminal; a third step of determining the NSSAI by using the URL information included in the HTTP message when the terminal executes the application and generates an HTTP message; and a fourth step of communicating with the 5G core network through a PDU session established for each network slice corresponding to the determined NSSAI.
