License-based Control for No. of HeNB Connections
Number of HeNBs connecting to the HeNB-GW are controlled/limited based on the license configuration.
Important:
SNMP traps are generated during Over/Under License capacity situation.
There are two scenarios for HeNBs connecting to the HeNB-GW: Through IPSec and Direcly HeNB-GW.
With IPSec (Integrated HeNB-GW and SeGW)
In case, IPSec is implemented or the Security Gateway is co-located with the HeNB-GW, IPSec Tunnel setup requests
are dropped once the number of tunnels exceed the configured license limit of the number of HeNBs.
are dropped once the number of tunnels exceed the configured license limit of the number of HeNBs.
Non-IPSec (Stanalone HeNB-GW)
HeNB-GW rejects the extra HeNB connection attempts with SCTP Abort once the license control is configured for
maximum number of HeNBs to connect to the HeNB-GW.
