Manual

The HeNB-GW may optionally terminate the user plane towards the HeNB and towards the S-GW, and may
provide a relay function for relaying User Plane data between the HeNB and the S-GW. The HeNB-GW
supports NAS Node Selection Function (NNSF).
NAS Node Selection Function (NNSF) supports S1-Flex or multiple S1-MME connections towards the
EPC from any one HeNB.
Important
HeNB Management System (HeMS)
It is a network element management system for HeNB access. Management interface between HeNB and
HMS is based on TR-069 family of standards. Femto access point extensions are based on standards as defined
in TR-196.
It performs following functions while managing HeNB access network:
•
Facilitates HeNB-GW discovery for HeNB(s)
•
Provision of configuration data to the HeNB
•
Performs location verification of HeNB(s) and assigns appropriate serving elements (HeMS, SeGW,
and HeNB-GW)
The HeNB 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 HeNB through Auto-configuration
server (HMS)
CSG List Server
The Closed Subscriber Group (CSG) List Server is an optional function which allows the EPC network to
update the allowed CSG lists on CSG-capable UEs.
The CSG List Server hosts functions used by a subscriber to manage membership to multiple as well as
different CSGs. For example, the CSG List Server includes the UE CSG provisioning functions which are
responsible to manage the Allowed CSG List and the Operator CSG list stored on the UE.
Licenses
The HeNB-GW is a licensed Cisco product. Separate session and feature licenses may be required. Each
HeNB-GW session corresponds to one IKEv2 session from an HeNB node when SeGW is integrated and
enabled. The license is based on the number of sessions and enables all HeNB-GW functionality, including
the following:
•
IKEv2 support, including all IKEv2 and IPSEC encryption/authentication
•
HeNB-GW service
