ITU-T H.812.3 (11/2015) i Recommendation ITU-T H.812.3 Interoperability design guidelines for personal health systems: WAN interface: Capability exchange certified device class Summary The Continua Design Guideli
10、nes (CDG) define a framework of underlying standards and criteria that are required to ensure the interoperability of devices and data used for personal connected health. They also contain design guidelines (DGs) that further clarify the underlying standards or specifications by reducing options or
11、by adding missing features to improve interoperability. This specification defines the additional design guidelines for the Capability exchange-enabled AHD and WAN device certified device class (CDC). The purpose of the capability exchange is to reduce the amount of information that must be pre-conf
12、igured on a device in order to obtain plug and play interoperability. Specifically, capability exchange enables application hosting devices (AHDs) to know what types of messages it can send to the WAN device, by identifying its Continua CDCs. Likewise, capability exchange provides a mechanism for th
13、e AHD to inform the WAN device of its capabilities, to enable the WAN device to tailor its communication with the AHD. Capability exchange is mandatory for all WAN devices while it is optional for AHDs. It is assumed that the AHD is pre-provisioned with a URL, or a set of URLs, denoting the service
14、endpoint of one or more WAN devices. The capability exchange process takes place when the AHD first contacts a WAN device. It may also take place intermittently, to update the information received in the first capability exchange. In most cases, the set of Continua CDCs implemented at a WAN device c
15、hanges slowly, if at all. Therefore, it is expected that the AHD can store the information about WAN capabilities, and optionally, implement a policy for periodically updating that cache. An AHD might identify several WAN devices in this way, and communicate with one or more for different purposes.
16、The WAN device describes the information about its supported CDCs in a file called “root file“. The root file is a special resource that describes the properties of CDCs and how AHD can start information exchange with these CDCs. The root file and other features of the exchange come from an HL7 stan
17、dard called hData . It not only defines the root file format, but also defines the operations for exchanging root files, using HTTP using GET and POST operations, often referred to as “REST“ (for representational state transfer). Each Continua CDC (in addition to capability exchange) will use the ro
18、ot file to document information relevant to that capability, including the capability name, the information that can be exchanged under the capability and its format, and URLs for REST operations, if supported by that capability. Details are given in the documentation for the respective Continua CDC

ITU-T H.812.3 (11/2015) iii FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, informa
24、tion and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a world
25、wide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WT
26、SA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication adminis
27、tration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provis
28、ions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to
29、the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside
30、 of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the lates
31、t information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2016 All rights reserved.
