The present document is part of a set of specifications, which describe the requirements and information model necessary for the standardised Operation, Administration and Maintenance (OA&M) of a multi-vendor UTRAN-system.
During the lifetime of an UTRAN network, 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.
Many of the activities involved in the daily operation and future network planning of a UTRAN network 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.
Annex B of TS 32.404 helps in the definition of new performance measurements that can be submitted to 3GPP for potential adoption and inclusion in the present document. Annex B of TS 32.404 discusses a top-down performance measurement definition methodology that focuses on how the end-user of performance measurements can use the measurements.

The present document describes the measurements for Universal Terrestrial Radio Access Network (UTRAN).
TS 32.401 describes Performance Management concepts and requirements.
The present document is valid for all measurement types provided by an implementation of a UTRAN. Only measurement types that are specific to UTRAN are defined within the present documents.
Vendor specific measurement types used in UTRAN are not covered. Instead, these could be applied according to manufacturer's documentation.
Measurements related to "external" technologies (such as ATM or IP) as described by "external" standards bodies (e.g. ITU-T or IETF) shall only be referenced within this specification, wherever there is a need identified for the existence of such a reference.
The definition of the standard measurements is intended to result in comparability of measurement data produced in a multi-vendor network, for those measurement types that can be standardised across all vendors' implementations.
The structure of the present document is as follows:
  • Header 1: Network Element (e.g. RNC related measurements);
  • Header 2: Measurement function (e.g. soft handover measurements);
  • Header 3: Measurements.
