Local Breakout (LBO)

Local Breakout enables the Mobile Network Operator (MNO) to break out Internet sessions into the Home network, to provide inbound roamers with an ability to order data, which is provided directly by the visited network.

LBO allows mobile subscribers to sign up to an alternative roaming provider separate from their HPLMN (Home Public Land Mobile Network). It enables inbound roamers to receive data services directly from the visited mobile network instead of tunneling back to the HPLMN. It offers lower latency experienced by the roaming device and has a lower GRX bandwidth requirement between the Home network and Visited network.

A major benefit is that it allows mobile subscribers to sign up to an alternative roaming provider. By targeting inbound roamers that choose to turn off mobile data instead of paying standard roaming charging rates, the solution allows the MNO to bring in revenue from a previously non-monetized source.
