LTE Enterprise small cell AP, JLT622P, provides wireless access to LTE UE, and it is connected to MME (Mobility
Management Entity) for control plane signaling via S1-MME logical interface. For the user data service, JLT622P
is connected to S-GW (Serving-Gateway) via S1-U logical interface. Connection between EPC and LTE small
cells may go through HeNB-GW instead of directly getting connected to EPC.
S-GW is connected to P-GW (PDN-Gateway) for external network access including Internet service. JLT622P
supports IPSec with Security-GW when it is deployed in public network. It carries out either USIM-based or
Certificate-based authentication procedure for creating IPSec tunnel to Security-GW located in front of HeNB-
GW. Security-GW may co-locate with HeNB-GW.
In addition, it has been proved in the field to work seamlessly with our cutting-edge management system HeMS
and SON server for plug and play-based configuration including automatic parameter setting, alarm reporting,
statistics gathering and interference mitigation.
