HNB Subsystem is defined in TS 23.060 [6]. According to the definition, a HNB subsystem consists of a HNB and a HNB GW. The HNB Subsystem 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.

Detailed functions of HNB and HNB GW are described in TS 25.467 [7]. To be more specific, HNB is a Customer Premise Equipment that offers the Uu Interface to the UE. It provides RAN connectivity and supports RNC like functions as well as UE registration over Iuh. HNB Gateway (HNB-GW) terminates Iuh from HNB and appears as an RNC to the existing Core network using existing Iu interface. It supports HNB registration and UE registration over Iuh.

Based on the above characteristics, this specification defines respective HNS NRM IRP requirements.
