Instances of ICT resources that UCS can orchestra
10、te include file, printer, monitor and keyboard. With UCS service, smart devices, such as smart phones and smart pads, can utilize local and/or remote ICT resources to configure the users own work space. Supplement 42 to ITU-T Y-series Recommendations provides a description of the UCS concept and its
11、 associated enhanced user experience. Also, this Supplement provides use cases of UCS service to illustrate how this service can be implemented.

13、6) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for s
14、tudying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study g
15、roups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis wit
16、h ISO and IEC. NOTE In this publication, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

The advantage of a smart device
30、 is its portability; to increase its portability, the size of a smart device tends to be small. However too small UIs caused by such small size make sometimes it difficult to work with applications, word processor for instance. To satisfy portability as well as usability, existing problems can be ov
31、ercome by orchestrating near-by and/or remote ICT resources in order to configure ones own work environment; for example, if there are available nearby office devices (such as monitor, keyboards, printers, facsimiles, etc.) that are allowed to be used, a user can borrow those devices as if his/ her
32、own with the aid of such orchestrating capabilities. This Supplement describes such personalized work environment called user-centric work space (UCS). Figure 1 depicts the concept of user-centric work space (UCS) which can be used as a personalized work environment. Figure 1 The concept of user-cen
33、tric work space (UCS) UCS can be provided by the UCS service to the service user by orchestrating one or more ICT resources and associating them with the service users smart device. The UCS service regards the ICT resources as service capabilities offered by a device. As a device may have one or mor
34、e service capabilities (for instance, an all-in-one printer which has printing, scanning and other service capabilities), each service capability offered by the device can be mapped into one or more ICT resources. In this Supplement, the ICT resources are regarded as virtual things and the service c
35、apabilities offered by the device are regarded as physical things ITU-T Y.4000. Figure 2 presents three ways of configuring UCS. Y series Supplement 42 (08/2016) 3 Figure 2 Three ways of configuring UCS The three ways of configuring UCS are: When a user wants to configure UCS with local ICT resource
36、s, requiring access to local devices (in both wired and wireless manner), the user communicates with devices in the physical world in order to orchestrate virtual things in the information world. An example of such a way of configuring UCS is shown by UCS of smart device A in Figure 2. When a user w
37、ants to configure UCS with remote ICT resources (e.g., hard disk, web camera and fax in other location), requiring access to remote devices, the user communicates with devices in the physical world via gateway in order to orchestrate virtual things in the information world. An example of such a way
38、of configuring UCS is shown by UCS of smart device B in Figure 2. When a user wants to configure UCS with ICT resources which are already involved in another UCS (e.g., to access printing services not available in his/her own UCS), requiring then the collaboration of UCSs, the user communicates with
39、 the other UCSs smart device in the physical world in order to share virtual things in the information world between the two UCSs. An example of such a way of configuring UCS is shown by the collaborated UCS shown in Figure 2. 7 Enhanced user experience with UCS service Figure 3 shows a current typi
40、cal work environment. At every place visited by a user, he/she faces different work environments: at home he/she uses his/her home PC, at office he/she uses an office PC, and at a caf he/she uses a smart phone. If the user wants to continue to use the services offered by his/her work environment, fo
41、r example word processing, then he/she needs to re-configure the work environment by installing new software. 4 Y series Supplement 42 (08/2016) Figure 3 Discontinuous user experience with UCS service Figure 4 shows a work environment with UCS service capabilities. UCS configured by UCS service capa
42、bilities provides its service users with continuous work environment wherever he/she is. Once UCS is configured, a user does not need to install new software to continue to use his/her work environment. Figure 4 Continuous user experience with UCS service 8 Use cases of UCS service Based on the UCS
43、service capabilities described in clause 6, this clause presents several tangible use cases of UCS service. 8.1 Nomadic office work environment 8.1.1 Scenario Figure 5 shows a scenario where a UCS can be used as a nomadic office work environment. Alice and Bob, in business partnership, have a busine
44、ss meeting in Bobs office. Alice brings her smart device capable of UCS service capabilities to Bobs office; Bobs office is equipped with an extra-wide monitor, keyboard and printer, which can be used freely by visitors. Alice brings in her smart device a business contract document to be reviewed wi
45、th Bob, but Alice has still not finished her final modifications in that document. Alice tries to find any available peripheral devices to configure her own work environment. Once found, Alice connects her smart device to the available peripheral devices wirelessly, in order to configure her UCS. Af
46、ter the successful UCS configuration completion, Alice can make her final modifications in the business contract document. Y series Supplement 42 (08/2016) 5 Figure 5 Scenario of nomadic office work environment 8.1.2 Service flow In this scenario, Alice has her UCS consisting of a wide monitor and a
47、 printer as output means, and a keyboard as input means. Figure 6 shows the service flow for the nomadic office work environment use case. Figure 6 Service flow for nomadic office work environment 1 Alice discovers available ICT resources offered by peripheral devices (monitor, keyboard and printer)
48、. 2 Alice selects available ICT resources and connects to the selected ones. 3 Alice uses the keyboard as her input means. 4 Alice uses the monitor and printer as her output means. After the successful procedure completion, Alice can have her own UCS as described in clause 6. 8.2 Car infotainment 8.
49、2.1 Scenario Figure 7 shows a scenario where a UCS can be applied for the car infotainment environment. Alice takes Bobs car; Alice sits in the back seat and wants access to a car infotainment system, such as the car A/V system and backseat display. 6 Y series Supplement 42 (08/2016) Alice asks Bobs permission to have access to the cars A/V system and headrest display in order to configure her own UCS. Once Bob has given the permission, Alice connects her smart device
