Abstract
A session migration method includes sending, by a transmission management apparatus, registration request cancellation information to a subscriber information management apparatus in response to user plane security enforcement information of a packet data unit (PDU) session failing to match user plane encryption protection information of an evolved packet system (EPS). The registration request cancellation information is useable to indicate that the PDU session fails to support migration to the EPS, and the PDU session has been registered with the subscriber information management apparatus.
