Architecture
Below diagram describes the architecture of IURH HNBG Configuration Transfer.
Figure 9: IURH HNB Configuration Transfer Architecture
HNB1 and HNB2 both are registered with HNBGW using HNB Registration Procedure. During HNB
Registration Procedure, both the HNBs provide their CELL IDs and IP address for direct IURH connectivity
in the "Iurh signalling TNL Address" IE. This is how HNBGW knows about the SCTP-IP Address (Inner IP)
and the IURH TNL IP address of the HNBs.
As HNB2 registers, HNB1 identifies a change in neighbor list (i.e. a new CELL ID), by detecting HNB2 or
via HMS. At this point HNB1 requests the IP addresses of the Target HNB(s) for direct IURH connectivity
by sending HNBAP HNB Configuration Transfer Request with the newly detected CELL ID to the HNBGW.
HNBGW responds with HNB Configuration Transfer Response message to HNB1 providing information of
