Abstract: This application provides a session migration method and apparatus. When a terminal apparatus moves from a 5GS to an EPS, the terminal apparatus needs to establish a corresponding PDN connection in the EPS for a PDU session in the 5GS. Before establishing the PDN connection, the terminal apparatus needs to determine that a user plane security status of the PDU session matches user plane encryption protection information of the EPS. This avoids that a PDU session that does not satisfy a user plane security requirement is migrated to the EPS, and reduces unnecessary signaling overheads.

Abstract: Embodiments of this application provide a policy transmission method, and a communication apparatus and system. The method includes: A policy control network element sends a first request to a first network element, where the first request carries a policy request trigger of a first policy, and the first policy includes a user equipment UE policy or an access and mobility management AM policy. The policy control network element receives, from the first network element, an event corresponding to the policy request trigger. Then the policy control network element updates the first policy and sends the obtained second policy to a terminal via an evolved packet system EPS. When the terminal device accesses the EPS, for example, when the terminal device moves to the EPS, the second policy can be used to ensure continuity of a user service and improve user experience.
