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 platformindependent multivendor environment for
management of all components of a network.
