Study on enhancement of Ultra-Reliable Low-Latency Communication (URLLC) support in the 5G Core network (5GC) is conducting standardization effort holistically on network slicing. This article only gives the introduction of the standard progress from system architecture prospective. Beyond 3GPP SA, 3GPP RAN (Radio Access Network) WGs are also working on how RAN handles network slices. Because Virtualization is one of the enabling technology for network slicing, 3GPP is also closely collaborating with relevant network virtualization standard organizations, such as ETSI NFV ISG, to make sure the network slice can run in the virtualized environment and operators can have a seamless E2E network slice resource management capability including the virtualized resource for the network slices.

The S-NSSAI may be associated with a PLMN (e.g., PLMN ID) and have network-specific values or have standard values. An S-NSSAI is used by the UE in access network in the PLMN that the S-NSSAI is associated with.

Responsible for translating the communication service related requirement to network slice related requirements. Unlike other solutions, we don’t force you to use our centralized servers. We don’t harvest your data, then sell it on. We don’t tell you how things should work or look. Study on enhancing topology of the Service Management Function (SMF) and the User Plane Function (UPF) in 5G networks Study on access traffic steering, switch and splitting support in the 5G System (5GS) architecture; Phase 2 SA5 is the 3GPP telecom management working group. By the time this article is written, SA5 has completed the study on management and orchestration on network slicing (TR28.801) and just started the normative specification work for release 15 based on this study. It is expected to be completed by the second quarter of 2018, including:Study on architecture enhancements to support Group Communication System Enablers for LTE (GCSE_LTE)
