Annex C (normative):
Performance Measurement Object Model

This annex comprises the Object Model for Performance Measurement to complement the high level Object Model in GSM 12.00 [8].

The whole management approach defined in GSM 12.00 [8] defines all entities of GSM network as managed functions. These are BSS, MSC, HLR etc. and one or more of these can be contained in managed element and each of these functions can contain it’s own measurement function.

The SGSN and GGSN detailed, are additional to GSM 12.00 [8] due to the introduction of GPRS.

Model Structure and Content

The following measurement function model takes its basis from the proposed GSM 12.00 [8] high level model. Figure C.1 shows the containment tree of all the measurement Object Classes. The formal GDMO definitions of the Managed Object Classes concerning measurement functions are described in this subclause, except the "log", which is described in annex D under data transfer requirements.
