Universal AAA for hybrid accesses

Abstract

International audienceNowadays telecommunication operators which manage various network types are looking for convergence in different domains, from the access and aggregation to the core network. Moreover, in future 5G networks, the explosion of Internet of Things and the need of fixed and mobile convergence will imply strong requirements for more simplified and unified subscriber management. This will lead notably to seamless user experience when moving from a network to another. This paper proposes a pragmatic approach to operators for moving their networks smoothly to a really convergent subscriber data and session management system. It takes into account legacy mechanisms of subscriber management and introduces a universal Authentication, Authorization and Accounting (AAA) which aims at replacing progressively the legacy subscriber databases and helps in moving to a unified logical network element that will manage all subscriber's data and sessions. This paper illustrates the proposals with some use cases

A Survey on LPWAN-5G Integration: Main Challenges and Potential Solutions

“…5GC and LPWAN servers. To expand the scope of their customer base, operators have integrated NB-IoT into their cellular networks [155], [156]. Thus, it can be predicted that more LPWAN networks would be integrated into operators' cellular networks and more integrations would be implemented at the core level in the future.…”
