traffic download method and relative device in roaming scenario

摘要

the present invention relates to a download method and a relative device in a roaming scenario, to prevent traffic from a roaming subscriber's subscribed service from returning to a home location, thereby reducing inter-network traffic consumption , implementing a local interruption capability of a terminal in a roaming location, and improving the quality of service. the method in this modality of this request includes: receiving, by a v-cp visited core network control plan, a first message sent by an h-cp home core network control plan, where the first message includes a policy of local lbo outage based on a subscribed service, and the subscribed service is a service on which a local outage needs to be performed and which is owned by a user; and send, through v-cp, the lbo policy to a v-up visited core network user plan, so that the lbo policy is installed on the v-up to implement local interrupt processing for the subscribed service .
