CSCul58078 - HeNBGW: nwsvc- not handling Overload Start Stop msg from
MME
Feature Changes
Handling Overload Start Stop msg from MME
Overload start messages when received from MME(s) are sent to HeNBs using that Logical eNodeB as per received or
configured Traffic Load Reduction value.
configured Traffic Load Reduction value.
Overload Stop are sent to Henbs when received from MME(s) for which Start has been sent.
Previous Behavior: Overload messages used to get dropped on HeNBGW when received from MME.
HeNBGW will send HeNBGW GUMMEI to HeNB with S1 SETUP Response message to HeNB.
New Behavior: On receiving MME Overload Start message, HeNBGW shall use the Traffic Load Reduction
Indication IE to determine the percentage of HeNBs (attached to the same logical eNB which receives the message) to
which Overload Start message need to be relayed. If Traffic Load Reduction Indication IE is not present in the message,
HeNBGW will relay the message to a configurable percentage of HeNBs.

HeNBGW will relay the message to a configurable percentage of HeNBs.
HeNBGW also supports Automatic and Manual configuration to send Overload Stop if not received from MME.
HeNBGW will send aggregated GUMMEI list from all MMEs in a MME-pool of logical enodb to HeNB with S1
SETUP Response message to HeNB. Also GUMMEI list status changes for any MME (i.e. lost SCTP connection to
MME, new MME connections is up or receive MME configuration Update message which changes GUMMEI list for a
MME) shall be broadcasted to all HeNB attached to the logical eNB using MME configuration Update Message.

Customer Impact: Overload start and stop messages received from a MME are correlated as per received or
configured TLR which reduces signaling towards that MME.
