Lawful Intercept
The Cisco Lawful Intercept feature is supported on the SaMOG (CGW, MRME) Gateway. Lawful Intercept is a license-

Local Breakout Support
SaMOG Gateway supports the Local Breakout (LBO) feature to enable subscribers to access the Internet without having
to connect to the EPC or 3G core. The LBO feature is implemented by configuring a local P-GW or a local GGSN. All
subscribers of a particular APN will be locally broken out and will not connect to the P-GW or GGSN 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.
