Understanding the Service Operation 
 
The system provides wireless carriers with a flexible solution for providing Security Gateway (SeGW) and Home-
eNodeB Gateway (HeNB-GW) functionality for LTE Femtocell networks. 
The system functioning as an HeNB-GW is capable of supporting the following types of subscriber sessions: 
 
PS Session over S1AP: The subscriber is provided packet switch connection with different traffic class on PS 
session with P-GW in PS. 
 
Network-initiated Sessions: Network-initiated session procedures include Paging, Dedicated Bearers, UE 
disconnections etc. from CN side on HeNB-GW for a specific subscriber session and in turn HeNB-GW 
initiates the required procedures with HeNBs and CNs. 
Prior to connecting to the command line interface (CLI) and beginning the system's configuration, there are important 
things to understand about how the system supports these applications. This chapter provides terminology and 
background information that must be considered before attempting to configure the system.
