gNodeB

compound module

This module implements a gNodeB for a 5G LTE network. It extends the eNodeB module by providing 5G connectivity to NRUe modules. It can be used in either StandAlone (SA) or Non-StandAlone (NSA) 5G deployments. In the former case, it is directly connected to a Upf module. In the latter case, this module can be configured as a secondary node of a eNodeB module, thus enabling E-UTRA Dual Connectivity (EN-DC).

Name	Type	Description
eNodeB	compound module	This module models an evolved Node B (eNB) of a 4G LTE network. It is a specialized device equipped with a Network Interface Card (NIC) that enables communication with the Ue devices connected to it. It serves as an access point that routes packets between the UEs and the 4G Core Network. Packets arriving from the UEs are tunneled to the appropriate next hop in the core network (e.g., the PDN Gateway, PGW) using the GPRS Tunneling Protocol (GTP). Conversely, packets received from the core network are detunneled and sent to the appropriate destination UE. In addition to the 4G NIC, this compound module includes a configurable number of wired interfaces to connect with routers of the core network or directly to the PgwStandard module, which serves as the IP module to perform forwarding, and the GtpUser module that handles GTP (de)tunneling. The latter utilizes the TrafficFlowFilter module to classify incoming packets and determine the next hop. Furthermore, it features a configurable number of LteX2App modules to facilitate peer-to-peer communications with other eNodeBs within the same LTE network.
