Abstract

Embodiments of this application disclose an offloading method and a related device in a roaming scenario, to prevent traffic of a subscribed service of a roaming subscriber from looping back to a home location, thereby reducing inter-network traffic consumption. The method in this embodiment of this application includes: receiving, by a visited core network control plane V-CP, a first message from a home core network control plane H-CP, where the first message includes a local breakout LBO policy based on a subscribed service, and the subscribed service is a service on which local breakout needs to be performed and that is of a user; and sending, by the V-CP, the LBO policy to a visited core network user plane V-UP, so that the LBO policy is installed on the V-UP to implement local breakout processing for the subscribed service.
