"The present document describes the measurements for Universal Terrestrial Radio Access Network (UTRAN). TS 32.401 [1] 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 inUTRAN 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."
