The Hanging Protocol Storage Service Class defines an application-level class-of-service that allows one DICOM AE to send a Hanging Protocol SOP Instance to another DICOM AE.
The Hanging Protocol Storage Service Class consists of a single SOP Class: the Hanging Protocol Storage SOP Class. It uses the Hanging Protocol IOD that represents the Hanging Protocol IE. This IOD is defined in PS3.3. The Hanging Protocol Storage Service Class uses the C-STORE DIMSE Service specified in PS3.7. A successful completion of the C-STORE has the following semantics:
Both the SCU and the SCP support Hanging Protocol information.
The Hanging Protocol information is stored in some medium.
For some time frame, the Hanging Protocol information may be accessed.
Support for the Hanging Protocol Storage SOP Class does not imply support for the Hanging Protocol Query/Retrieve Service Class.
The duration of the storage is also implementation dependent, but is described in the Conformance Statement of the SCP.
The Hanging Protocol Storage SOP Class is intended to be used in a variety of environments: e.g., for workstations to transfer Hanging Protocol SOP Instances to other workstations or archives, for archives to transfer Hanging Protocol SOP Instances to workstations, etc.
