Explain advanced RAN Slicing related features

Base Package · SA

RAN Slicing Framework

FAJ 121 5095 — Base Package · Stand Alone
Slice-aware AMF selection via NSSAI from UE
Slice-aware QoS mapping · NG-based handover
Enhanced N21.Q2: accessibility/retainability observability · N21.Q3: slice throughput observability
Benefit: end-to-end network slicing · SLA-based services · tailored customer offerings

SA · 5G RAN + 5GC

Network Slicing Overview

A network slice is a logical network serving a defined business purpose or customer
Consists of all required network resources configured together
Created, changed, and removed by management functions
Provides resource reservation, differentiated traffic handling, and guaranteed SLA resources
Network slice is an enabler for services — not a service itself

Value Package

Advanced RAN Slicing VP — FAJ 801 4019

EN-DC RAN Slicing Support — Slice awareness in NSA deployments
NR Relative Priority Scheduling FAJ 121 5293 — RPS values within priority domains
NR Radio Resource Partitioning — Dedicated resource pools per slice
RPS value = 2 means scheduled twice as often as RPS = 1 within same domain

FAJ 121 5293

Relative Priority Scheduling

Relative priority applies between users within the same priority domain
Highest absolute priority domain served first (n−1 before n+1)
Steeper weight curve = higher relative priority = more frequent scheduling
Can combine with Priority Controlled Scheduling for absolute + relative differentiation
Enhanced N21.Q2: adjust relative priority by Packet Delay Budget difference
