This section describes the optional enhanced features and functions for SaMOG service. 

  The following features require the purchase of an additional feature license to implement the

The Cisco Lawful Intercept feature is supported on the SaMOG (CGW, MRME) Gateway. Lawful Intercept is a license-
enabled, standards-based feature that provides telecommunications service providers with a mechanism to assist law 
enforcement agencies in monitoring suspicious individuals for potential illegal activity. For additional information and 
documentation on the Lawful Intercept feature, contact your Cisco account representative. 

SaMOG Gateway supports the Local Breakout (LBO) feature to enable subscribers to access the Internet without having 
to connect to the EPC core. The LBO feature is implemented by configuring a local P-GW. All subscribers of a 
particular APN will be locally broken out and will not connect to the P-GW over the S2a interface. SaMOG performs IP 
allocation locally. This capability helps APNs whose data traffic is expected to hit the internet immediately after 
authentication instead of being sent to 3GPP backbone. 

The following figure provides a high level architecture of the Local Break Out feature:
