The present document is part of a TS-family covering the 3rd Generation Partnership Project: Technical Specification Group Services and System Aspects; Telecommunication management, as identified below: 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 PLMN. During the lifetime of a PLMN, 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 PLMN 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 and the other related 3GPP TSs listed above is to describe the mechanisms involved in the collection of the data.

The present document describes the general semantics of performance measurement result and collection. It defines the report file format, report file conventions and the file transfer procedure. Clause 4 specifies the file format for the bulk transfer of performance measurement results to the NM, while clause 5 discusses the file transfer procedure utilised on that interface. The present document does not give the definition of any specific file format - such as XML and ASN.1, which will be given in Performance Measurement eXtensible Markup Language (XML) File Format Definition TS 32.435 and Performance Measurement Abstract Syntax Notation 1 (ASN.1) File Format Definition TS 32.436.
