Procedures
BreezeCOMPACT Full Configuration via CLI
¾ In order to configure TAC per ENB run the command below:
 At the BreezeCompact% prompt, enter the following command:
set cell tracking-area tac <Track area code number >
¾ In order to show the TAC configured in the ENB run the command below
from the BreezeCompact% prompt
 show cell tracking-area
As a result you should get the output as per the example below : tac 1;
3.3.2.5.1
PLMN-ID setting
The BreezeCOMPACT support multiple PLMN-IDs to enable multi-service modes, each
PLMN-ID can be supported by the EPCs in the network. Once PLMN-IDs are set the eNodeB
publish over the air to all UEs the available PLMN-IDs, according to the UE logic it decides
which PLMN ID will be selected. In case UE does not select the PLMN-ID, the default PLMN-
ID is used by the eNodeB.
In order to Set PLMN IDs:
 set cell tracking-area p
plmn-identity-list 011111 is-primary true
is-primary settings :
true – The PLM-ID is the default PLMN-ID false – non default PLMN-ID
¾ In order to show the PLMN ID configured in the ENB run the command
below from the BreezeCompact% prompt
 Show cell tracking-area plmn-identity-list
As a result you should get the output as per the example below : plmn-identity-list 00101;
3.3.2.5.2
Load Balancing & Redundancy setting
The Load-balancing mechanism is applied during a new UE Attach procedure. eNB may be
provisioned with multiple EPCs (MMEs) in a load-balancing/ failover mode.
BreezeCOMPACT supports two pools of MMEs (EPCs) for load balancing – Primary and
Secondary.
EPC load balancing is used within the pool – either Primary or Secondary. If no resources or no
available MME entities event occurs in the Primary pool, eNB will switch to the Secondary
pool. When resources of the Primary pool recover, eNB will switch back to use it (for a new-
coming UEs)
Note, that BreezeCOMPACT supports multiple PLMNIDs concept for EUTRAN sharing and
multi-service networks convergence. In this case, BreezeCOMPACT will sort out all the MMEs
(EPCs) per PLMNID – effectively, this will result in Primary/ Secondary EPC pools per each of
the configured PLMNIDs (MME provides its PLMNID to eNB during S1 Setup).
eNB balancing the UE sessions between MMEs during UE Attach. The eNB balancing
algorithm takes into account EPC relative capacity and actual eNB load for the particular
EPC. “EPC relative capacity” is the number configured in EPC and provided to eNB during S1
setup. It is proportional to EPC licensed capacity. “Actual capacity”- is the local eNB counter
that represents the number of active UE sessions on the particular EPC.
