In this second part of "15 Mins with 5G" we will start looking at the 3GPP specifications for 5G network architecture and learn how to refer the specs. We will also cover 5G deployment scenarios from the specs as well as some of the informative web resources.
Reading the specifications have certain challenges.
#1 - Homogeneous Deployment
#2 - Heterogeneous Deployment
#3 Heterogeneous deployment
LTE eNB as Master Node
gNB as master node
eLTE eNB as master node
Individual RAT with Inter Mobility
Inter-working with WLAN
5G radio offers downlink data throughput up to 20Gbps and uplink data throughput up to 10Gbps. Some of the interfaces in EPC are capable of handling (encode/decode) 5G throughput ranges
LTE Protocols & Interfaces
NAS (MBR, GBR)
GTP-v2 interfaces - S5/S8/S10/S3
Diameter - S6a and Gx
Note: New AVP (Attribute Value Pairs)/IE(Information Elements) have been introduced in S6a, Gx , S1-AP and NAS to support 5G.
In 5G, the RAN node is referred to as the Next Generation RAN (NG-RAN). Radio Access Network (RAN) node connects to the UPF and AMF
The NG-RAN node is either a gNB or a ng-eNB, as follows
The gNBs and ng-eNBs are interconnected with each other by means of the Xn interface
Central Unit (CU) and Distributed Unit(DU) Functional Split Options
5G System architecture - Reference point representation
5G System architecture - Service-based representation
