5G = NR + eLTE 5G comprises: • New Radio (NR) • enhanced Long Term Evolution (eLTE)
• Next Gen Core • Evolution of EPC
From EPC to EPC+, a temporary 5G Core solution
-
•
EPC+ inherit all the EPC Functions and Features
•
EPC+ Extend to support 5G eMBB services as following:
1. QoS Extension to support eMBB High Bandwidth
-
2. Networking Extension for core support NR Access
-
3. Others Enhancement on MME, PCRF…

6 Key difference form EPC to 5G Core 1
• Service based architecture
4
− Enable each NF to interact with other
− Support local breakout and may have
NF directly via service based interface
parallel nodes serving the same APN
− Benefit: Agility & Open
2
• Native Support CUPS
− Benefit: Best User Experience
5
− Dedicated UPF (user plane) with various
3GPP, non-3GPP, Fix access
− Benefit: Simply & Efficiency
Modularize the function design − AMF/SMF/PCF… evolution from MME/PCRF， New NFs (NEF/UDR…) − Benefit: Flexible & Open
• Converged access-agnostic core − with a common AN - CN interface for
control plane
3
• Native support MEC and Continuity
− Benefit: Simply & Efficiency
6
• Network Slicing for diverse services − E2E resource include RAN and Core − 3 Standardized Slice/Service type − Benefit: Flexible & Automotive

Network Slicing with 3 typical Slice/Service type A network slice comprises E2E resources : • the Core Network CP &UP • the NG RAN or N3IWF to non-3GPP Access An S-NSSAI (Network Slice Selection Assistance Information) identifies a Network Slice. An SNSSAI is comprised of: • A Slice/Service type (SST), which refers to the expected Network Slice behaviour in terms of features and services; • A Slice Differentiator (SD), which is optional information that complements the Slice/Service type(s) to differentiate amongst multiple Network Slices of the same Slice/Service type. Slice/Service type (SST) eMBB (enhanced Mobile Broadband) URLLC (ultra- reliable low latency communications) MIoT (massive IoT)
