X2 Handover Procedure Support
In order to support X2 Handover between HENBs, the HeNB-GW should provide the HeNB with the MME UE S1AP
ID allocated by the MME and HeNB-GW within the S1 HANDOVER REQUEST along with the S1 INITIAL
CONTEXT SETUP REQUEST messages. HeNB-GW may also inform the HeNB about any GUMMEI corresponding
to the serving MME.
ID allocated by the MME and HeNB-GW within the S1 HANDOVER REQUEST along with the S1 INITIAL
CONTEXT SETUP REQUEST messages. HeNB-GW may also inform the HeNB about any GUMMEI corresponding
to the serving MME.
HENBGW have to route S1 PATH SWITCH REQUEST message from HENB towards the MME based on the
GUMMEI of the source MME received from the HeNB. If HENBGW receives CSG ID IE and Cell Access Mode IE in
the S1 PATH SWITCH REQUEST, the same should be forwarded to MME. In case of S1 PATH SWITCH REQUEST
ACKNOWLEDGE message, HENBGW will inform the HeNB about the MME UE S1AP ID assigned by the MME and
the MME UE S1AP ID assigned by the HeNB GW for the UE.

ACKNOWLEDGE message, HENBGW will inform the HeNB about the MME UE S1AP ID assigned by the MME and

HENBGW will receive UE CONTEXT RELEASE REQUEST message with an explicit GW Context Release
Indication from Source HENB at the end of X2 Handover Procedure phase. Therefore the HeNB GW terminates the S1
UE Context Release Request procedure and releases the UE context if it determines that the UE identified by the
received UE S1AP IDs is no longer served by a HeNB attached to it or it ignores the message.

MME Pool size
HeNBGW supports 32 MMEs max per MME pool. Pool size is increased from 8 to 32 MMEs per logical eNB with
which HeNBGW can interact. The maximum associations will now be 256 (8 LeNB x 32 MME).

Cell Broadcast Support
The Cell Broadcast Support is in compliance with the Warning system aspects of the S1-MME interface between
eNodeB and MME, and the S1AP protocol defined by the 3GPP specification TS 36.413 Release 10.
