Supported Logical Interfaces
This section provides the brief information on supported interfaces on HNB-GW node.
In support of both mobile and network originated subscriber UE contexts, the HNB-GW provides the following network
interface support:
interface support:
IuH Interface: This interface is the reference point for the control plane protocol between Home NodeB and
HNB-GW. IuH uses SCTP over IPSec IKEv2 tunnel as the transport layer protocol for guaranteed delivery of
signaling messages between HNB-GW and Home NodeB.
signaling messages between HNB-GW and Home NodeB.
This is the interface used by the HNB-GW to communicate with HNB on the same Femtocell Access Network.
This interface serves as path for establishing and maintaining subscriber UE contexts.
