performs many of the function of a Node B, but is optimized for deployment in the indoor premises and small coverage public hotspots. The

concept was originally conceived for residential environment. However, it has evolved to include other usages such as enterprise and public hotspots. Home eNode B is an LTE counterpart of the HNB.

Architecture

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. Between the HNB and the HNB-GW is a new interface known as Iu-h. 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

as well as the radio resource management functions of a standard Radio Network Controller RNC. 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.

Logical Interface

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.
