N-CREATE service procedures

The following N-CREATE procedures apply:

a) The invoking DIMSE-service-user requests the creation and registration of a new managed SOP Instance by issuing an N-CREATE request primitive to the DIMSE-service-provider.

b) The DIMSE-service provider issues an N-CREATE indication primitive to the performing DIMSE-service-user.

c) If the operation can be performed, the performing DIMSE-service-user creates and registers the new managed SOP Instance and generates a response indicating acceptance of the N-CREATE request primitive by issuing an N-CREATE response primitive to the DIMSE-service-provider. In this case the following procedure does not apply.

d) If the operation cannot be performed, then the performing DIMSE-service-user rejects the N-CREATE request by issuing an N-CREATE response primitive with the appropriate error code to the DIMSE-service-provider.

e) The DIMSE-service-provider issues an N-CREATE confirmation primitive to the invoking DIMSE-service-user, completing the N-CREATE operation.

The performing DIMSE-service-user may return an N-CREATE response primitive with the status of Failed or Refused before the entire N-CREATE indication (Data Set) has been completely transmitted by the invoking DIMSE-service-user. A N-CREATE response primitive with the status of Success or Warning shall not be returned until the entire N-CREATE indication has been received by the performing DIMSE-service-user.

Note: Such an occurrence of a "Failed" response is often called an early failed response.
