Pico LTE small cell, JLT733A, 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,
JLT733A 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.
JLT733A 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.
