B.2 Behavior

This Section discusses the SCU and SCP behavior for SOP Classes of the Storage Service Class. The C-STORE DIMSE-C Service shall be the mechanism used to transfer SOP Instances between peer DICOM AEs as described in PS 3.7.

B.2.1 Behavior of an SCU

The SCU invokes a C-STORE DIMSE Service with a SOP Instance which meets the requirements of the corresponding IOD. The SCU shall recognize the status of the C-STORE service and take appropriate action upon the success or failure of the service.

Note: The appropriate action is implementation dependent. It is required that the SCU distinguish between successful and failed C-STORE responses. Appropriate action may differ according to application, but are described in the Conformance Statement of the SCU.

B.2.2 Behavior of an SCP

An SCP of a Storage SOP Class acts as a performing DIMSE-service-user for the C-STORE Service. By performing this service successfully, the SCP indicates that the SOP Instance has been successfully stored.

B.2.3 Statuses

Table B.2-1 defines the specific status code values which might be returned in a C-STORE response. General status code values and fields related to status code values are defined in PS 3.7.
