Concept Description
Cell site gateway (CSG) A device that receives and processes various service signals from base stations and forwards them to devices at the aggregation layer.
Access aggregation gateway (AGG) A device that aggregates service signals from CSGs and forwards them.
Radio network controller site gateway (RSG) A device that connects to a controller.
Base transceiver station (BTS) A 2G base station. Mobile communication systems are composed of mobile stations, base station subsystems (BSSs), and network subsystems (NSSs). BSSs are composed of BTSs and base station controllers (BSCs).
NodeB A 3G base station. NodeBs are interconnected with radio network controllers (RNCs) through standard Iub interfaces and communicate with UE nodes through Uu interfaces, processing Uu interface physical layer protocols and Iub interface protocols.
eNodeB An E-UTRAN NodeB or LTE base station.
RNC A key node on a 3G network, which manages mobility, processes calls, manages links, and switches users on the access network.
BSC A key node on a 2G network, which manages radio network resources and cell information, controls power, and locates and switches users.
Mobility management entity (MME) A key control node on a 3GPP LTE access network, which locates UE nodes in idle mode and processes calls (including regeneration).
