A mobile network is composed by the following parts:
- Mobile Station (MS)
- The base stations subsystems (BSS)
- The network and switcing subsystem (NSS)
- The operations and support subsystem (OSS)
Mobile Station (MS):
- the mobile equipment (Ex: phone)
- the SIM (Subscriber identity Module) card that uniquely identified the card by the IMSI (International Mobile Subscriber Identity).
The base station subsystem (BSS):
- base station (BTS) - it defines a cell in the network
- base station controller (BSC) - controls a group of BTSs. Does handoffs, frequency hoppings, exchange functions and power control over each managed BTS
The network and switching subsystem(NSS)
- MSC
- VLR
- HLR
- AUC
- EIR
- GMSC
