Abstract
A session management function (SMF) receives, from a user plane function (UPF), a data notification message for a multi access packet data unit (MA PDU) session. The data notification message comprises access information associated with a child session of the MA PDU session. The access information indicates an access type and an identifier of a session between the SMF and the UPF associated with the MA PDU session. The SMF determines to activate the child session of the MA PDU session based on the data notification message. The SMF sends, to an access and mobility management function (AMF), based on the determining, a request indicating activation of a user plane connection via the access type. The SMF sends, to the UPF, a session modification request indicating activation of the user plane connection.
