Performance Management (PM) is a key functionality that provides the operator with visibility into how its network is performing. Performance measurements and KPIs are critical inputs into optimization of networks. Accurate and a rich set of counters delivered in a timely manner is essential for trouble shooting purposes and enable support for automatic identification of network problems and automatic error correction and optimization of the network.
To that effect, there is a need to provide consistent counters for all elements in a converged network.
3GPP has specified with the PM IRP (3GPP TS 32.41x ) an interface for Performance Management. TMF has in MTOSI and OSSJ capabilities for Performance Management as well. Currently TMF TIP studies how Performance Management can be aligned inside TMF.
However, there is no reason why PM functions should be different, and an aligned management approach would greatly benefit the industry. An example of alignment within 3GPP SA5 IRP work is that multiple Solution Sets are aligned in that their supported management features are identical. Advantages of alignment include:
CAPEX reduction (less development cost, less integration cost)
OPEX reduction (consistent handling of performance measurements collection)
The present document provides consistent and aligned PM and PM interfaces in 3GPP and TMF. The present document:
identifies similarities and differences of the PM capabilities in 3GPP and TMF TIP PM BA;
proposes enhancements to 3GPP PM solutions for converged networks and to satisfy TMF TIP PM BA requirements;
identifies any required changes in the 3GPP specifications;
identifies any required changes in the TMF specifications (to be communicated to TMF).
Backwards compatibility of the PM IRP should be maintained as much as possible by re-using existing specifications to the maximum extent.
The counter collected by each of the Network Elements (NE) and the definition of those are NE specific and there is no intention to harmonize those.
However KPIs with a network view should be explored.
