Limitations
MINE server support available either through actual server or tools.
IPNE service configuration and associations will remain as they were in the previous release of HNBGW.
Grid based paging
Grid based paging is the way to find a UE amongst the HNBs by the HNBGW. Paging is complicated for the
below reasons:
•
UE can be in idle/unregistered state when HNBGW tries to page HNBs
•
UE may not be at the HNB from which it was registered the last time
•
Some HNBGW deployments may have around 500K active HNBs and it is not favorable to page all to
locate the UE
•
There are policies and optimizations to stop HNBGW from flooding the network with paging requests
Requirements for Grid Based Paging
•
HNBGW is expected to remember the Grid Id of the HNB where the UE was last seen
•
HNBGW is expected to fan out the paging request only to the HNBs which have matching Grid-Id to
the HNB where the UE was last seen. The paging request will not be sent to the HNBs which have a
different Grid-Id
•
When the UE moves out to HNB which has a different LAC than the existing one, it is supposed to do
location update
•
RMS will provide the Grid ID (Enterprise ID, Site ID, and Group ID Tuple) in the access accept message
Assumptions and Limitations
The Grid ID will come to HNBGW from RMS via radius interface. The Grid Id contains Enterprise ID + Site
ID + Group ID.
It is expected that for the HNBs belonging to the same Grid Id will have the same LAC.
IURH based F2F handoff
IURH based F2F Handoff Requirements
The IURH interface to connect UEs between HNBs is defined in 3GPP. Following is the protocol stack of
the IURH interface:
RNA
SCTP
IP
L2/L1
