HNBAP
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) Standard The following 3GPP documents are available: 3GPP TR 25.469: HNBAP Technical Report- A technical report that looks at the UTRAN Iuh interface Home Node B (HNB) Application Part (HNBAP) signalling - A technical report that looks at the air interface and requirements for the protocols to link the Home NodeB to the core network - End to end architecture UTRAN architecture for 3G Home NodeB (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 ...

Home Node B
A Home Node B, or HNB, is the 3GPP's term for a 3G femtocell or Small Cell. A Node B is an element of a 3G macro Radio Access Network, or RAN. A femtocell performs many of the function of a Node B, but is optimized for deployment in the indoor premises and small coverage public hotspots. The femtocell 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 Node B as well as the radio resource management fu ...

Node B
{{Unreferenced, date=May 2019, bot=noref (GreenC bot) Node B is the telecommunications node in particular mobile communication networks, namely those that adhere to the UMTS standard. The Node B provides the connection between mobile phones ( UEs) and the wider telephone network. UMTS is the dominating 3G standard. Node B corresponds to BTS (base transceiver station) in GSM. Functionality This is the hardware that is connected to the mobile phone network that communicates directly with mobile handsets. In contrast with GSM base stations, Node B uses WCDMA/TD-SCDMA as the air interface technology. As in all cellular systems, such as UMTS and GSM, the Node B contains radio frequency transmitter(s) and the receiver(s) used to communicate directly with mobile devices, which move freely around it. In this type of cellular network, the mobile devices cannot communicate directly with each other but have to communicate with the NodeB. Traditionally, the Node Bs have minimum functionali ...

Radio Network Controller
The Radio Network Controller (RNC) is a governing element in the UMTS radio access network (UTRAN) and is responsible for controlling the Node Bs that are connected to it. The RNC carries out radio resource management, some of the mobility management functions and is the point where encryption is done before user data is sent to and from the mobile. The RNC connects to the Circuit Switched Core Network through Media Gateway ( MGW) and to the SGSN (Serving GPRS Support Node) in the Packet Switched Core Network. Interfaces The logical connections between the network elements are known as interfaces. The interface between the RNC and the Circuit Switched Core Network (CS-CN) is called Iu-CS and between the RNC and the Packet Switched Core Network is called Iu-PS. Other interfaces include Iub (between the RNC and the Node B) and Iur (between RNCs in the same network). Iu interfaces carry user traffic (such as voice or data) as well as control information (see ), and Iur interface is ...
