Radio Network Controller (RNC)

Target entity: Radio Network Controller (RNC)
Context triple: [3GPP Release 99, introduces, Radio Network Controller (RNC)]

• A. BSC (Base Station Controller)
  BSC (Base Station Controller) is a key mobile network component that manages radio resources and controls multiple base transceiver stations (BTS) within a cellular system.
• B. eNodeB
  eNodeB is the base station in LTE networks responsible for radio transmission, reception, and control functions between user devices and the core network.
• C. Gateway Mobile Switching Centre
  The Gateway Mobile Switching Centre (GMSC) is a key GSM network component that routes calls between mobile networks and external networks such as the public switched telephone network (PSTN).
• D. Serving GPRS Support Node
  The Serving GPRS Support Node (SGSN) is a core network component in 2G/3G mobile systems responsible for delivering data packets to and from mobile devices and managing their mobility and session states.
• E. E-UTRAN
  E-UTRAN is the LTE mobile network’s air-interface subsystem that connects user devices to the core network via evolved base stations (eNodeBs).
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
