7.2.1 Overview

An initial view of Performance Management is described in [105]. This shows an example decomposition of Performance Management processes to identify essential information flows. It shows a slice through the Telecom Operations Map from a Performance Management point of view. This slice is applicable to Mobile Networks and other networks. Although the "slice" or view is quite large, it does not contain all interfaces or process activities that are related to Performance Management. It does however show the main processes and interfaces involved in Performance Management. Please refer to [105] for further detail.

7.2.2 Standardisation objectives

During the lifetime of a 3GPP system, its logical and physical configuration will undergo changes of varying degrees and frequencies in order to optimise the utilisation of the network resources. These changes will be executed through network configuration management activities and/or network engineering, see TS 32.600 [54].

Many of the activities involved in the daily operation and future network planning of a 3GPP system require data on which to base decisions. This data refers to the load carried by the network and the grade of service offered. In order to produce this data performance measurements are executed in the NEs, which comprise the network. The data can then be transferred to an external system, e.g. an Operations System (OS) in TMN terminology, for further evaluation. The purpose of the present document is to describe the mechanisms involved in the collection of the data and the definition of the data itself.

The Performance Management functional area concerns the management of performance measurements and the collection of performance measurement data across a 3GPP system. It defines the administration of measurement schedules by the Network Element Manager (EM), the generation of measurement results in the Network Elements (NEs) and the transfer of these results to one or more Operations Systems, i.e. EM(s) and/or Network Manager(s) (NM(s)).

The management requirements have been derived from existing telecommunications operations experience. The management definitions were then derived from other standardisation work so as to minimise the re-invention factor. References are given as appropriate.

The objectives of the present document are:

– To provide the descriptions for a standard set of measurements;

– To produce a common description of the management technique for measurement administration and result accumulation; and

– To define a method for the bulk transmission of measurement results across a management interface.

The definition of the standard measurements is intended to result in comparability of measurement data produced in a multi-vendor 3GPP system, for those measurement types that can be standardised across all vendors’ implementations.

As far as possible, existing standardisation in the area of Performance Management is re-used and enhanced where particular requirements, peculiar to the mobile telephony environment, have been recognised.

Performance management is further specified in TS 32.400-series [53].
