In case henbgwmgr restart, overload stops will be sent to all overload flagged HeNBs in sessmgr.
Automatic congestion control recovery:
For each OCHL, a configurable guard timer will be started. If there is no overload stop received from
the MME before the timer expires, overload stop will be sent to all corresponding HeNBs.
Manual congestion control recovery:
Henbgw will provide CLI command to send overload stops to all HeNBs in a OCHL of a MME.
SoC compliance will be updated to S1AP specifications.
DHCPv4 Proxy support for HeNBGW with IPSec
The DHCPv4 proxy functionality on the SeGW integrated with HeNBGW is to update the DHCP messages with the
HeNB Id in DHCP Option 61 (Client ID) and forward the DHCP messages to an external DHCP server.
HeNB Id in DHCP Option 61 (Client ID) and forward the DHCP messages to an external DHCP server.
How DHCPv4 Proxy support for HeNBGW with IPSec works
1. The SeGW forwards DHCP requests from a LTE FAP to an external DHCP server during IPSec Setup.
2. The SeGW adds LTE FAP Id in the Client Identifier (CID) of the DHCP messages.
3. The PNR then receives these DHCP requests maintains a mapping between the LTE FAP ID and the assigned

"Inner" IP Address
4. The RMS queries the PNR to get the LTE FAP inner IP Address, to use this inner IP Address to send TR-069
Connection Requests to the LTE FAP.
HeNBGW Multi Operator Core Network (MOCN)
MOCN is a network sharing technology that allows different core network operators to connect to a shared radio access
network. One HENB can handle more than one core network operator. In this scenario HENB broadcasts a list of
PLMN Ids to UE's. UE's supporting MOCN functionality decode the broadcast system information sent by HENB and
are able to select a core network operator as the serving operator within a shared network.
