A Novel 5G Core Network Capability Exposure Method for Telecom Operator

Abstract

Network capability exposure is an essential 5G network application. The flexible service-based architecture of the 5G core (5GC) network becomes the basement for the application of 5G network capabilities. In addition, it becomes a tendency to build a cooperative and win-win innovative business model between telecom networks and 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> party companies/affiliations. In this paper, we focus on 5GC network capability application. Initially, this paper analyzes the scenarios and use cases as well as their corresponding 5GC network capability requirements. Then, this paper introduces the 5GC network exposure architecture and functions. In addition, this paper proposes an improved traffic influence capability exposure method. According to the 5GC lab experimental test, the end-to-end service transfer delay and rate have been improved. The proposed traffic influence capability exposure method can assist telecom operators for the 5GC network capability application and deployment.
