The Base Station Subsystem BSS provides the connection between the mobile stations and
the Network Subsystem NSS. The NSS forwards user signals to other mobiles via the BSS
or subscribers in the Public Switched Telephone Network (PSTN), and provides necessary
customer data. The Operation & Maintenance Subsystem (OMS) monitors BSS and NSS
performance, and remotely debugs occurring faults in the network elements.

Additional components such as interface elements to data networks, the Short Message
Service Center or the Voice Mail System complete the GSM system architecture.
