GSM BSS offers standard external interfaces including Um interface between MS and BSS, A interface between BSS and MSC. The interface protocols and interface procedures strictly follow the ETSI specifications. The interfaces between each BTS and BSC and those between BSS and OMC are internal interfaces, and are related to specific equipment from different manufacturers. There are many regulations drafted by ETSI for the Abis interface between BTS and BSC, but the regulations are still incomplete.
