"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."
