Table 10.1-2 N-GET PARAMETERS
|DIMSE Parameter Name||Req/Ind||Rsp/Conf|
|Message ID Being Responded To||⎯||M|
|Requested SOP Class UID||M||⎯|
|Requested SOP Instance UID||M||⎯|
|Attribute Identifier List||U||⎯|
|Affected SOP Class UID||⎯||U|
|Affected SOP Instance UID||⎯||U|
This parameter identifies the operation. It is used to distinguish this operation from other notifications or operations that the DIMSE-service-provider may have in progress. No two identical values for the Message ID (0000,0110) shall be used for outstanding operations or notifications.
Note: The Message ID (0000,0110) is recommended to be unique within the scope of an Association, to support debug procedures.
This parameter specifies the Message ID (0000,0110) of the operation request/indication to which this response/confirmation applies.
This parameter specifies the SOP Class for which Attribute Values are to be retrieved.
This parameter specifies the SOP Instance for which Attribute Values are to be retrieved.
This parameter contains a set of Attribute identifiers for which the Attribute Values are to be returned by the performing DIMSE-service-user. If this parameter is omitted, all Attribute identifiers are assumed. The definitions of the Attributes are found in the specification of the Information Object Definition in PS 3.3.
This parameter may be included in the response/confirmation. If included in the response/confirmation, this parameter shall be equal to the Requested SOP Class UID parameter value used in the request/indication.
This parameter specifies the SOP Instance for which Attribute Values are returned. It may be included in any response/confirmation and when included shall be equal to the Requested SOP Instance UID (0000,1001) parameter value used in the invocation.
This parameter contains the set of Attribute identifiers and values which are returned by the performing DIMSE-service-user. It shall be included in the success response/confirmation.
This parameter contains the error or success notification for the operation. It shall be included by the performing DIMSE-service-user in any response/confirmation. The following types of status may occur:
⎯ attribute list error: one or more Attribute Values were not read because the specified Attribute was not recognized. The Attribute Values that could be read are returned.
⎯ class-instance conflict: the specified SOP Instance is not a member of the specified SOP Class.
⎯ duplicate invocation: the Message ID (0000,0110) specified is allocated to another notification or operation.
⎯ invalid SOP Instance: the SOP Instance UID specified implied a violation of the UID construction rules.
⎯ mistyped argument: one of the parameters supplied has not been agreed for use on the Association between the DIMSE-service-users.
⎯ no such SOP class: the SOP Class was not recognized.
⎯ no such SOP Instance: the SOP Instance was not recognized.
⎯ processing failure: a general failure in processing the operation was encountered.
⎯ resource limitation: the operation was not performed due to resource limitation.
⎯ success: successful operation.
⎯ unrecognized operation: the operation is not one of those agreed between the DIMSE-service-users.
