HNB Gateway in Wireless Network
Figure 5. HNB Provisioning and Registration Setup Call Flow
1. HNB initialization is performed to obtain HNB configuration from the HNB Management System (HMS).
Similarly, HNB-GW discovery is performed to obtain the initial serving HNB-GW information.
2. A secure tunnel is established from the HNB to the Security Gateway.
3. Location verification shall be performed by the HMS based on information sent by the HNB (e.g. macro
neighbor cell scans, global navigational satellite system type of information etc.). HMS determines the serving
elements and provides the HNB-GW, HMS and Security Gateway to the HNB. The HMS also provisions
configuration parameters to the HNB only after successful location verification in the HMS.
4. Reliable transport setup (SCTP) completed and the HNB sets up a SCTP transport session to a well-defined port
on the serving HNB-GW. HNB Registration procedure started.
5. The HNB attempts to register with the serving HNB-GW using a HNB-REGISTER-REQUEST message. This
message may contains:
 HNB Location Information: The HNB provides location information via use of one or more of the
OL-25069-03
following mechanisms:
 detected macro coverage information (e.g. GERAN and/or UMTS cell information)
 geographical co-ordinates (e.g. via use of GPS, etc)
