- 10. 10 2G (RAN) BTS (Base Station Transceiver) BTS is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity. BSC (Base Station Controller) BSC is a critical mobile network component that controls one or more base transceiver stations (BTS), also known as base stations or cell sites. Key BSC functions include radio network management (such as radio frequency control), BTS handover management and call setup. It also carries transcoding of speech channels.
- 11. 11 3G (RAN) NodeB NodeB is a term used in UMTS equivalent to the BTS (base transceiver station) description used in GSM. RNC (Radio Network Controller) RNC is a governing element in the UMTS radio access network (UTRAN) and is responsible for controlling the NodeBs that are connected to it. The RNC carries out radio resource management, some of the mobility management functions and is the point where encryption is done before user data is sent to and from the mobile.
- 12. 12 2G/3G CN (Core Network) Core Network is split into CS domain and PS domain. CS domain is based on original GSM network. PS domain is based on original GPRS network. CS domain: used to provide Circuit-switched service. Network mode can support TDM, ATM and IP. Physical entities include switching equipment (such as MSC/VLR, GMSCs, HSS), and inter-working equipment (IWF). PS domain: used to provide Packet-switched service. Network mode is IP. Physical entities include SGSN, GGSN, CG , BG etc.
