Simulating LTE RAN and EPC networks using ns-3 key building blocks
Having discussed ns-3 supporting LTE features and how to set up and configure various LTE network nodes, we can start setting up LTE/4G network simulations in a hands-on activity in this section. In this hands-on activity, we focus on setting up complete LTE EPS (RAN and EPC) and handling the following tasks:
- As part of LTE RAN, deploy two eNBs with a distance of 500 meters between them
- Deploy a minimum of 20 LTE UEs near each eNB
- Configure eNBs and UE transmission power as 46 dB and 20 dB, respectively
- Configure UL and DL bandwidths to 25 RBs
- Configure propagation loss model and error models
- Configure LTE RRC parameter SRS based on the number of UEs to connect with eNB
- Install LTE UE and eNB protocol stacks
- Set up EPC and connect with RAN
- Set up an internet host and connect with a P-GW using a 10 Gbps P2P link
- Test automatic UE attach and manual attach procedures to connect...
