25 DICOM PS c - Network Communication Support for Message Exchange Page 25 7 OSI Upper Layer Service for DICOM Application Entities This section provides a description of how to use the OSI Association Control Service Element (ACSE) and OSI Presentation Layer to provide the Upper Layer Service necessary to support the communication of DICOM Application Entities. This Upper Layer Service is a fully conformant subset of the services offered by the ACSE and the OSI Presentation Layer. The UL Services are listed in Table 7-1. Table 7-1. Upper Layer Services A-RELEASE SERVICE A-ASSOCIATE A-ABORT A-P-ABORT P-DATA TYPE Confirmed Confirmed Non-Confirmed Provider-initiated Non-Confirmed In addition to the Upper Layer Service specification, this section defines at the parameter level the use of each element of this Upper Layer Service by DICOM Application Entities. The rules guiding the use of this Upper Layer Service by the DICOM Application Entities are addressed in PS A-ASSOCIATE Service The establishment of an association between two AEs shall be performed through ACSE A-ASSOCIATE request, indication, response and confirmation primitives. The initiator of the service is hereafter called a requestor and the service-user that receives the A-ASSO- CIATE indication is hereafter called the acceptor. It shall be a confirmed service. The A-ASSOCIATE service supports the equivalent of a channel establishment in a point-to-point interface (see the retired PS3.9). Figure 7-1 illustrates the association establishment between two AEs. A-ASSOCIATE request Requestor DICOM UL Service Provider Acceptor A-ASSOCIATE indication A-ASSOCIATE response A-ASSOCIATE confirmation ( SAP ) ( SAP ) Figure 7-1. Associate Request
26 Page 26 DICOM PS c - Network Communication Support for Message Exchange A-ASSOCIATE Parameters Table 7-2 lists the parameters that shall be required for the A-ASSOCIATE service used by DICOM Application Entities in this standard. Table 7-2. Key A-ASSOCIATE Service Parameters A-ASSOCIATE parameter name Request Indication Response Confirmation application context name M M(=) M M(=) calling AE title M M(=) M M(=) called AE title M M(=) M M(=) user information M M(=) M M(=) result M M(=) result source M diagnostic U C(=) calling presentation address M M(=) called presentation address M M(=) presentation context definition list M M(=) presentation context definition list result M M(=) See Section 5 of this part for table conventions. Table 7-3 lists the parameters for the A-ASSOCIATE service that shall contain fixed values or shall not be used by DICOM Application Entities in this standard. Table 7-3. A-ASSOCIATE Service Parameter (Fixed or Not Used) A-ASSOCIATE parameter name Request Indication Response Confirmation mode UF MF(=) responding AE title MF MF(=) calling/called/responding AE qualifier NU NU NU NU calling/called/responding AP invoc-id NU NU NU NU calling/called/responding AE invoc-id NU NU NU NU responding presentation address MF MF(=) default context name/result NU NU NU NU presentation & session requirements UF UF(=) UF UF(=) other parameters (see ISO 8822 & 8649) NU NU NU NU Mode (Fixed) This parameter allows the negotiation of the optional Mode OSI-ACSE Service parameter. Only the default value of "normal" is used by DICOM Application Entities. Therefore, this parameter shall always specify the value "normal." Application Context Name This parameter identifies the application context proposed by the requestor. The acceptor shall return either the same or a different name. The returned name shall specify the application context to be used for this association. Further discussion on Application Context Names can be found in Annex A.
27 DICOM PS c - Network Communication Support for Message Exchange Page 27 An application context is an explicitly defined set of application service elements, related options, and any other information necessary for the interworking of application entities on an association. The offer of an alternate application context by the acceptor provides a mechanism for limited negotiation. If the requestor cannot operate in the acceptor's application context, it shall issue an A-Abort request primitive. Application Context Names for the DICOM Application Entity as well as Application Context Names usage rules are defined in PS Calling AE Title This parameter identifies the Application Entity (AE) that shall contain the requestor of the A-ASSOCIATE service. It is based on the Source DICOM Application Name. The relationship between DICOM Application Names and AE titles is specified in Annex C. The Calling AE title may or may not be the same as the Initiator Address present in DICOM Messages exchanged over the association. It is the responsibility of the UL User that received the A-ASSOCIATE-RQ to verify whether the Calling AE Title is one of its known remote DICOM Application Names Called AE Title This parameter identifies the Application Entity that shall contain the intended acceptor of the A-ASSOCIATE service. It is based on the Destination DICOM Application Name. The relationship between DICOM Application Name and AE titles is specified in Annex C. The Called AE title may or may not be the same as the Receiver Address present in DICOM Messages exchanged over the association. It is the responsibility of the UL User that received the A-ASSOCIATE-RQ to verify whether the Called AE Title is its (or one of its) DICOM Application Name(s) Responding AE Title (Fixed) This parameter identifies the AE that shall contain the actual acceptor of the A-ASSOCIATE service. In this standard it shall always contain the same value as the Called AE Title of the A-ASSOCIATE indication User Information This parameter shall be used by the requestor and the acceptor of the association to include DICOM Application Entity user information. Its meaning shall depend on the application context that accompanies the primitive. The usage of this parameter is specified in Annex D. 1. This parameter is used to carry initialization information for the DICOM Application Entities as defined in the application context specified by the value of the accompanying Application Context Name parameter. 2. Annex D specifies some user information sub-items, and references PS3.7 for the specification of additional sub-items. PS3.7, in turn, references PS3.4 for the specification of Service-class-application-information used in some sub-items Result This parameter shall be provided either by the acceptor of the A-ASSOCIATE request, by the UL service-provider (ACSE related function), or by the UL service-provider (Presentation related function). It shall indicate the result of using the A-ASSOCIATE service. It shall take one of the following symbolic values: a. accepted; b. rejected (permanent); c. rejected (transient).
28 Page 28 DICOM PS c - Network Communication Support for Message Exchange The rejected (permanent) implies that the association calling UL user (when returning such a result to an association request) does not need to "call later." A permanent situation exists that prevents the association establishment (e.g., remote DICOM Application Name unknown) Result Source The value of the parameter is supplied by the UL service-provider. It identifies the creating source of the Result parameter and the Diagnostic parameter, if present. It shall take one of the following symbolic values: a. UL service-user; b. UL service-provider (ACSE related function);c) UL service-provider (Presentation related function). If the Result parameter has the value "accepted," the value of this parameter is "UL service-user." Diagnostic This parameter shall only be used if the Result parameter has the value of "rejected (permanent) " or "rejected (transient)." It shall be used to provide diagnostic information about the result of the A-ASSOCIATE service. If the Result Source parameter has the value "UL service-user," it shall take one of the following symbolic values: a. no-reason-given b. application-context-name not supported c. calling-ae-title not recognized d. called-ae-title not recognized e. calling-ae-qualifier not recognized (see note) f. calling-ap-invocation-identifier not recognized (see note) g. calling-ae-invocation-identifier not recognized (see note) h. called-ae-qualifier not recognized (see note) i. called-ap-invocation-identifier not recognized (see note) j. called-ae-invocation-identifier not recognized (see note) If the Result Source parameter has the value "UL service-provider" (ACSE related function), it shall take one of the following symbolic values: a. no-reason-given b. no-common-ul version If the result source has the value "UL service-provider" (Presentation related function), it shall take the following symbolic values: a. no-reason-given b. temporary-congestion c. local-limit-exceeded d. called-(presentation) -address-unknown
29 DICOM PS c - Network Communication Support for Message Exchange Page 29 e. Presentation-protocol version not supported f. no-(presentation) Service Access Point (SAP) available Even though some of the above symbolic values correspond to parameter errors not used in this standard, they are included to allow the notification of errors resulting from the unauthorized use of these parameters Calling Presentation Address This parameter shall contain a structured destination address unambiguous within the global network address structure. This shall be a TCP/IP Address. See Annex C Called Presentation Address This parameter shall contain a structured destination address unambiguous within the global network address structure. This shall be a TCP/IP Address. See Annex C Responding Presentation Address In this standard, a responding presentation address shall always contain the same value as the called Presentation Address of the A-ASSOCIATE indication. This parameter shall contain a structured destination address unambiguous within the global network address structure Presentation Context Definition List This parameter used in an A-ASSOCIATE request or indication shall consist of a list containing one or more presentation contexts. Each item shall contain three components, a presentation context identification, an Abstract Syntax Name, and a list of one or more Transfer Syntax Names. The presentation context identification components of this parameter exist to distinguish presentation contexts in communication. Such an identification of presentation context(s) applies only within the context of a given association (i.e., different presentation contexts may be identified by the same presentation context identification on different associations). It is the association-requestor's responsibility to assign an arbitrary, but unused identifier for each proposed presentation context on a given association. There is no restriction on the ordering of the presentation contexts in relation to their identifiers. A separate presentation context will be associated with each Abstract Syntax Name in each of the elements of the Presentation Context Definition List parameter. If the same Abstract Syntax Name occurs more than once, a separate and distinctly identified presentation context will be generated for each occurrence (as only one Transfer Syntax per presentation context can be accepted). Abstract Syntaxes defined by this standard and used by DICOM Application Entites are defined in PS3.4. Transfer Syntaxes defined by this standard and used by DICOM Application Entities are defined in PS3.5. Further discussion on Abstract Syntaxes and Transfer Syntaxes can be found in Annex B Presentation Context Definition Result List This parameter used in the A-ASSOCIATE Response and Confirmation indicates the acceptance or rejection of each of the presentation context definitions proposed in the presentation context definition list parameter (Section ). The Presentation Context Definition Result List parameter shall take the form of a list of result values. There is a one to one correspondence between each one of these result values and each of the presentation contexts proposed in the Presentation Context Definition List parameter. Each result value represents either "acceptance," "user-rejection," or "provider-rejection." The values of the results are assigned by the UL user on the response service primitive. The result values may be sent in any order.
