Abstract
This application provides a method, an apparatus, and a system for sending a terminal policy. After determining that a terminal is not reachable, a mobility management network element may send, to a visited policy control function network element, a notification indicating that a first message fails to be forwarded. The visited policy control function network element may determine, based on the notification, a first PTI allocated by a home policy control function network element to a first policy, and send, to the home policy control function network element, both the first PTI and the indication indicating that the first message fails to be forwarded, to notify the home policy control function network element.
