The scope of this Recommendation1 is to provide a test suite structure and the test purposes (TSS TP) for the WAN interface based on the requirements defined in the Continua Design Guidelines (CDG) [ITU-T H.810]. The objective of this test specification is to provide a high probability of air interface interoperability between different devices. The TSS TP for the WAN Interface document have been divided into the eight parts specified below. This Recommendation covers Part 5. ?C Part 1: Web Services Interoperability. Sender ?C Part 2: Web Services Interoperability. Receiver ?C Part 3: SOAP/ATNA. Sender ?C Part 4: SOAP/ATNA. Receiver ?C Part 5: PCD-01 HL7 Messages. Sender ?C Part 6: PCD-01 HL7 Messages. Receiver ?C Part 7: Consent Management. Sender ?C Part 8: Consent Management. Receiver 1 This Recommendation includes an electronic attachment with the protocol implementation conformance statements (PICS) and the protocol implementation extra information for testing (PIXIT) required for the implementation of Annex A.
