Security Gateway (SeGW)

Security Gateway is a logical entity in Cisco HNB-GW. Basic function of this entity are; 1) authentication of HNB and
2) providing access to HMS and HNB-GW
This entity terminates the secure tunnelling for Iuh and TR-069 between HNB and HNB-GW and HMS respectively.
In this implementation it is an optional element which is situated on HNB-GW.

HNB Gateway (HNB-GW)

The HNB-GW provides the access to Femto user to UMTS core network. It acts as an access gateway to HNB and
concentrates connections from a large amount of HNBs. The Iuh interface is used between HNB and HNB-GW and
HNB-GW connects with the Core Networks (CS or PS) using the generic Iu (Iu-CS or Iu-PS) or Gn interface.
It also terminates Gn and other interfaces from UMTS core networks to provide mobile data services to HNB and to
interact with HMS to perform HNB authentication and authorization.

HNB Management System (HMS)

It is a network element management system for HNB access. Management interface between HNB and HMS is based
on TR-069 family of standards.
It performs following functions while managing HNB access network:
Facilitates HNB-GW discovery for HNB
Provision of configuration data to the HNB
Performs location verification of HNB and assigns appropriate serving elements (HMS, Security Gateway and
HNB-GW)
The HNB Management System (HMS) comprises of the following functional entities:
File Server: used for file upload or download, as instructed by TR-069 manager
TR-069 Manager: Performs CM, FM and PM functionality to the HNB through Auto-configuration server
