This document is the report of the 3GPP SA5 / TM Forum NGWW Joint Work Group on Fault Management
Harmonization. The analysis and recommendations in it are offered to 3GPP and TM Forum for further consideration in their work on Fault Management.
The background of the Fault Management Harmonization (FMH) project is the desire by operators and vendors to
reduce the integration tax and the network operating cost, which is believed to be possible by converging 3GPP and TM Forum fault management solutions.
The FMH team did a detailed comparison of the semantics of alarm management specifications from 3GPP and from
TM Forum and formulated a number of proposed changes to both specifications. This document describes the outcome
of that work.
In 2010, 3GPP SA5 and TM Forum NGWW agreed to start a study on the possibility to come to a single set of
management specifications which should work for wireless as well as for wireline networks. Fault Management (FM)
was chosen as one of the pilot subjects. From the start, it was clear that the simplest solution towards unification, being
to stop the work on one of the two solutions and promote the other solution as the single future solution for converged
network management was not feasible. Installed base and existing preferences in the market did not allow that solution.
Therefore the joint working group on FM harmonization decided to consider in detail the differences between the 3GPP and the TM Forum FM solutions and to discuss ways to remove those differences as much as possible so that the two solutions would evolve in a convergent way, instead of each being further developed independent of the other one.
It was recognized that just agreeing on syntactical matters would not be very helpful as the major effort in integration of different management solutions is in the alignment of semantic matters. Therefore it was agreed to work towards semantic harmonization.
