HNBAP is a control protocol found in
Home Node B networks on the Iu-h interface.
The Home Node B Application Part (HNBAP) protocol provides the following functions:
*Registration of HNB with the HNB-GW
*Identification of the HNB
*Registration of UE with the HNB-GW (through HNB)

Architecture
Between the HNB and the HNB-GW is a new interface known as Iu-h.
Iu-h Interface - Residing between an HNB and HNB-GW, the Iu-h interface defines the security architecture used to provide a secure, scalable communications over the Internet. The Iu-h interface also defines an efficient, reliable method for transporting Iu-based traffic as well as a new protocol HNBAP for enabling highly scalable ad hoc HNB deployment.
Within an HNB Access Network there are three new network elements: the
Home Node B (or femtocell), the Security Gateway (SeGW) and the Home Node B Gateway, or HNB-GW.
Home Node B (HNB) – Connected to an existing residential broadband service, an HNB provides 3G radio coverage for 3G handsets within a home. HNBs incorporate the capabilities of a standard

Security Gateway (SeGW) - Installed in an operator's network, the Security Gateway establishes IPsec tunnels with HNBs using IKEv2 signaling for IPsec tunnel management. IPsec tunnels are responsible for delivering all voice, messaging and packet data services between HNB and the core network. The SeGW forwards traffic to HNB-GW.
HNB Gateway (HNB-GW) - Installed within an operator's network, the HNB Gateway aggregates traffic from a large number of HNBs back into an existing core service network through the standard Iu-cs and Iu-ps interfaces.
