TMN Background

OSS functions in GSM are based on the concept of the Telecommunication Management Network (TMN).

TMN was standardised within ITU-T/ETSI/CEPT almost simultaneously with GSM.

ITU-T M. series recommendations M.20 and M.30 serve as the framework for TMN.

TMN defines an open system that enables platform-independent multivendor environment for management of all components of a network.
