This TS describes the measurements for UMTS and combined UMTS/GSM.
describes Performance Management concepts and requirements.
This TS is valid for all measurement types provided by an implementation of a UMTS network and combined UMTS/GSM network.
Only measurement types that are specific to UMTS or combined UMTS/GSM networks are defined within this TSs. Vendor specific measurement types used in UMTS and combined UMTS/GSM networks 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 TS, 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.
