FAQ's

Why implementing 5G RAN NSA?

5G Non Standalone (NSA) solution enables operators to launch 5G services in shorter time and leverage existing infrastructure. NSA leverages the existing LTE radio access and core network (EPC) to anchor 5G NR using the Dual Connectivity feature, providing a seamless option to deploy 5G services with very less disruption in the network. It is worth remembering that 5G NSA solution is fully 3GPP compliant and can inter-operate with any RAN and network functions.

How is 5G RAN NSA planned and implemented?

The E-UTRA-NR Dual Connectivity (EN-DC) functional feature supports 5G New Radio (NR) RAN connected to EPC. According to 3GPP standards a UE connected to an eNodeB acts as a Master Node (MN) and an en-gNB acts as a Secondary Node (SN). The eNodeB is connected to the EPC through the S1 interface and to the en-gNB through the X2 interface. The en-gNB can be connected to the EPC through the S1-U interface and other en-gNBs through the X2-U interface. 5G RAN NSA Planning and designing principles are more or less the same to LTE, with some minor changes related to cell coverage and RACH accessibility due to higher frequency bands, hence smaller cell coverage.

How is 5G NR NSA service established?

UE can connect to the LTE and 5G NR base station following the basic setup in high-level scheme: 1. The UE attaches to the LTE network. The UE signals to the network that it can simultaneously connect to the 4G and 5G networks. 2. The Core Network checks if the UE is authorized to connect to 4G and 5G networks. The 4G eNodeB is notified that the UE is permitted to connect to the 5G network. 3. The eNodeB then takes a decision to activate a bearer on the 5G gNodeB. 4. The 4G eNodeB and 5G gNodeB communicate to set up the bearer on the 5G gNodeB. 5. The UE is notified about the 5G bearer via the RRC Connection Reconfiguration message. 6. The UE then connects to the 5G network while maintaining the connectivity to the 4G network.
