ITU-T Y.2303 (01/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The
12、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 worldwide basis. The World Telecommunication Standard
13、ization 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 WTSA Resolution 1. In some areas of information te
14、chnology 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 administration and a recognized operating agency. Compl
15、iance 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 provisions are met. The words “shall“ or some other ob
16、ligatory 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 the possibility that the practice or implementat
17、ion 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 of the Recommendation development process. As o
18、f 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.

29、nt b-ITU-T H.780: A combination of audio, still image, graphic, video, or data. NOTE A variety of formats are classified as “data“ (e.g., text, encoded values, multimedia description language introduced by ITU-T H.760). 3.1.3 context b-ITU-T Y.2002: The information that can be used to characterize t
30、he environment of a user. NOTE Context information may include where the user is, what resources (devices, access points, noise level, bandwidth, etc.) are near the user, at what time the user is moving, interaction history between person and objects, etc. According to specific applications, context
31、 information can be updated. 3.1.4 context awareness b-ITU-T Y.2201: A capability to determine or influence a next action in telecommunication or process by referring to the status of relevant entities, which form a coherent environment as a context. 3.1.5 identity b-ITU-T Y.2720: Information about
32、an entity that is sufficient to identify that entity in a particular context. 2 Rec. ITU-T Y.2303 (01/2015) 3.1.6 network intelligence capability enhancement (NICE) ITU-T Y.2301: An enhancement for NGNs supporting some intelligence capabilities for the provisioning of services according to requireme

39、he context, “functions“ are defined as a collection of functionalities. It is represented with the following symbol: Functional entity: In the context, a “functional entity (FE)“ is defined as a set of one or more functions, and several functional entities constitute the “functions.“ It is represent
40、ed with the following symbol: Sub-functional entity: In the context, a sub-functional entity (SFE) is defined as a sub-function. The scope is smaller than a functional entity and several sub-functional entities constitute a “functional entity.“ It is represented with the following symbol: 6 Scenario
41、s of the content and context awareness functions in NICE The content and context awareness functions of NICE support the following scenarios: For network resource awareness, the content and context analysis functional entity (CA-FE) interacts with the management functions of transport stratum and wi
42、reless access network to gather the bandwidth utilization, cost of routes and other available resources information. For user traffic awareness, the content and context analysis functional entity (CA-FE) interacts with the content and context detection functional entity (CD-FE) to get the users serv
43、ice and traffic flow information. For user profile information awareness, the CA-FE interacts with the user profile FE and the open environment FE. For user terminal parameters awareness, the CA-FE interacts with user terminal to obtain the terminal type, OS type, access network information, etc. Th
44、e content and context analysis FE needs to interwork with the policy control FE to provide control policies, such as the status of access network. The content and context analysis FE supports the functions of analysis of the data of user, network, etc. The CA-FE also supports openness of the informa
45、tion of user and network to 3rd party, such as provide the users recent web visiting information to advertisement provider. Applications can access the CA-FE either through application support functions or policy control FE. In both cases, applications can configure the analysis policy of the CA-FE
46、in order to collect application-related contents on demand rather than receive the complete information extracted by the CA-FE. Functions Functional entity (FE) Sub-functional entity (SFE) 4 Rec.

47、ew of the content and context awareness functional architecture in NICE Figure 7-1 Overview of the content and context awareness functional architecture in NICE Figure 7-1 shows the overview of the content and context awareness functional architecture in NICE. In NICE architecture, the CA-FE and the
48、 CD-FE are two main FEs that play the role of awareness functions. These two FEs interact with other FEs and functions in NICE, such as the policy control FE, the traffic scheduling FE, and the open environment FE to provide awareness analysis data or results. Beyond NICE architecture, the awareness
49、 functions also reside in the NGNs, e.g., the CPE functions, the management functions, the service user profile FE, etc. These FEs and functions interact with the CA-FE and the CD-FE as awareness resource data inputs.
