5G Core network service-based architecture evolution

Abstract： In 3GPP release 15, service-based architecture work item mainly finished the mechanism of service discovery. However, communication between network functions is still in a direct way which adopts point-to-point pattern and is hard for operations in future complicated network environment. At the same time, there is no mature protecting measure for the reliability of network functions. This paper mainly studies on the evolution of service-based architecture in 5G Core. More specifically, it analyzes the indirect communication method based on service communication proxy and gives the advantages and implementation suggestions. Also, it analyzes the high reliability mechanism of the network function set as well as the network function service set and gives the evolution of network functions as focusing on computing and removing the functionalities of storage and switching.
