Local Breakout - Enhanced
The Local Breakout (LBO) - Enhanced model is implemented by configuring a local P-GW or a local GGSN. All
subscribers of a particular APN will be locally broken out without connecting to the P-GW or GGSN over the S2a
interface. SaMOG performs IP allocation locally. This capability helps APNs whose data traffic can connect to the
Internet immediately after authentication, instead of being sent to the 3GPP backbone.
