Feature Changes
SaMOG Local Breakout Support
With this release, SaMOG extends support for 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 PGW. All
subscribers of a particular APN will be locally broken out and will not connect to PGW over the S2a interface. SaMOG
performs IP allocation locally.

performs IP allocation locally.
The APN provided by AAA is mapped to the locally configured PGW service IP. This eliminates the need for a DNS.
The local PGW assigns the IP using a locally configured IP pool after receiving the subscriber information from AAA.
Subscriber information is received from the SaMOG service to the local PGW service through a GTP tunnel. This
tunnel is set up with in the same chassis.

The MRME service provides the following functionality:
If the AAA server requests a local breakout support for the subscriber, MRME service communicates the same
to CGW during call setup.
If the AAA server does not provide any indication for a local breakout support, or if the AAA server requests
support for both local breakout and EPC core connection, MRME service determines if a local breakout
support is needed for a session by looking up the apn-profile at the local policy. The decision is communicated
to CGW during call setup.
