The present document describes the measurements of IMS.
3GPP TS 32.401  describes Performance Management concepts and requirements.
The present document is valid for all measurement types provided by an implementation of an IMS network. These may be measurement types defined within the present document, measurements defined within other standards bodies, or vendor specific measurement types.
Only measurement types that are specific to IMS network are defined within the present documents. I.e. vendor specific measurement types and measurements related to "external" technologies used in IMS network, such as ATM or IP, are not covered. Instead, these could be applied as described by the other, "external" standards bodies (e.g. ITU-T or IETF) or according to manufacturer's documentation.
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. measurements related to CSCF);
- Header 2: Measurement function (e.g. Registration related measurements);
- Header 3: Measurements.
