A DIMSE Command that does the following: “Application A asks application B to send DICOM Instances stored in Application B to Application C”.
Application C may or may not be application A itself. When Application B receives the C-MOVE Request it initiates communication with Application C and then performs C-STORE commands for every instance that matches the C-MOVE request identifier. While doing this, Application B may report progress to application A through the connection that A initiated originally when requesting the C-MOVE.
