Abstract
Provided are method and apparatus for maintaining an air interface inactive state. The method includes: receiving an RRC uplink notification message sent by a UE, the RRC uplink notification message carrying information notifying that the UE is out of coverage of a serving cell under a source secondary node; performing, based on the RRC uplink notification message, a migration operation of a related high-level configuration of a PDU session anchored to the source secondary node by the UE, a migration target node being a target secondary node or a current master node; and sending an RRC downlink reply message to the UE after performing the migration operation of the high-level configuration, and maintaining the UE in a dual-connectivity or single-connectivity air interface inactive state.
