The HNB-GW provides HNB registration and de-registration procedure to register the HNB with the HNB-GW. This
procedure enables the HNB-GW to provide service and core network connectivity for the HNB. On HNB-GW node this
procedure is the first HNBAP procedure triggered after the SCTP association has become operational between HNB and
HNB-GW.

HNB management function processes the HNB/UE access control procedure through White-List processing on HNB-

Hybrid Access Mode Support
A Closed HNB provides services only to the mobile subscribers which are member of the associated access control
database (IMSI Whitelist). An HNB operating in Hybrid (Semi-Open) access mode provides services to other mobile
subscribers along with members of the associated access control database whereas an Open HNB provides its services to
any mobile subscriber.

any mobile subscriber.
HNB-GW supports Hybrids Access mode for Hybrid HNBs to expand its access control to Open, closed, and Hybrid
HNB access.
HNB access.
This feature provides following procedure for Hybrid Access HNB registration on HNB-GW:
Hybrid HNB registration:
1. HNB-GW associates a set of access-controlled IMSIs (whitelist) with every Hybrid-HNB. For a Hybrid
HNB, the whitelist is send by AAA-server in the Radius-Access-Accept message to the HNB-GW.
The whitelist associated with a Hybrid HNB can also be empty.
The whitelist associated with a Hybrid HNB can also be empty.
2. HNB-GW supports the modification of the whitelists associated with Hybrid HNBs. AAA-Server can
send a COA message to the HNB-GW to change the whitelist associated with a Hybrid HNB.
HNB-GW does not support modification of the cell-access-mode of registered HNBs using RADIUS
CoA message.
HNB-GW supports Open, Closed and Hybrid access mode HNBs simultaneously.
HNB-GW provides a configuration to disable the registration of Hybrid HNBs.
UE registration:
1. HNB-GW supports guaranteed successful registration of the access-controlled (whitelisted) UEs
associated with Hybrid HNBs.
2. A configuration is provided to control the maximum number of simultaneously registered non-access-
controlled UEs from a Hybrid HNB.
Paging: Support paging of UEs simultaneously via Open, Closed and Hybrid HNBs
Hand-in and Hand-out: HNB-GW supports UEs’ hand-in/hand-out relocation requests towards/from Hybrid
HNBs. HNB-GW supports hand-in relocation for access-controlled UEs only.
Important:
For more information on Hybrid Access Mode support configuration, refer Hybrid Access Mode
Configuration section of HNB-GW Administration Guide.
Intra-Domain Multiple CN Support Through Iu-Flex
Iu-Flex is the routing functionality for intra domain connection of HNB-GW nodes to multiple CN nodes (MSC/SGSN).
It provides a routing mechanism and related functionality on HNB-GW to enable it to route information of different
Core Network (CN) nodes with in the CS or PS domain. It is implemented in accordance with the following standards:
