A Home eNodeB, or HeNB, is the 3GPP's term for a LTE femtocell or Small Cell. A eNodeB is an element of a LTE Radio Access Network, or E-UTRAN. A HeNB performs the same function of an eNodeB, but is optimized for deployment for smaller coverage than macro eNodeB, such as indoor premises and public hotspots. Home Node B is 3G (UMTS) counterpart of the HeNB. ==Architecture== Within an HeNB Access Network there are three new network elements: the Home eNodeB, the Security Gateway (SeGW) and the Home eNodeB Gateway, or HeNB-GW. Home eNodeB (HeNB) – A HeNB provides LTE radio coverage for LTE handsets. HeNBs incorporate the capabilities of a standard eNodeB. Security Gateway (SeGW) - Installed in an operator’s network, the Security Gateway establishes IPsec tunnels with HeNBs using IKEv2 signaling for IPsec tunnel management. IPsec tunnels are responsible for delivering all voice, messaging and packet data services between HeNB and the core network. The SeGW forwards traffic to HeNB-GW. HeNB Gateway (HeNB-GW) - It is an optional network element (NE) installed within an operator’s network. If it is present, it is placed between the HeNB and the MME and it aggregates traffic from a large number of HeNBs back into an existing core service network through the standard S1 interface. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Home eNode B」の詳細全文を読む スポンサード リンク
