Telecommunication management; Performance Management (PM); Performance measurements Home Node B (HNB) Subsystem (HNS)
The present document describes the measurements for Home Node B subsystem (HNS).
HNS [3] is consists of a HNB and HNB-GW. And, it appears as an RNS to the core network and is connected by means of the Iu-CS interface to the MSC and by means of the Iu-PS interface to the SGSN.
TS 32.401 [4] describes Performance Management concepts and requirements.
The present document is valid for all measurement types provided by an implementation of a HNS.
Only measurement types that are specific to HNS are defined within the present documents. Vendor specific measurement types used in HNS 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. measurements related to HNB and HNB GW);
-	Header 2: Measurement function (e.g. HNB registration measurements);
-	Header 3: Measurements.
