10、ernational 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 studying technical,
11、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 groups which, in tur
12、n, 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 with ISO and IEC. NOTE
13、 In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e
14、.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 obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not
15、suggest that compliance with the Recommendation is required of any party.

Furthermore,
32、it monitors the data exchange process and takes actions when specific user data is encountered after the data exchange process. A typical form of the functional component is an extensible markup language (XML) parser combined with application-dependent logic. 3.2.2 depository: A depository is a loca
33、tion where the user data could be stored or kept so that it could be accessed later. It can take various forms such as internal or external memory of terminals, network storage servers and other storage devices. 3.2.3 user data: “User data“ is the data that is created or stored in terminals or netwo
34、rk entities by the users, and is related to the private information, historical operations performed by the user, personal tendencies or favourite user settings. It is independent of whether this data is transported by terminal or network entities, and has no correlation with the counterpart of “Con
35、trol data“. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: DRM Digital Rights Management DXA Data exchanging Agent FTP File Transfer Protocol HTTP Hypertext Transfer Protocol IM Instant Message MMS Multimedia Message Service RAM Random Access Memory R

37、neral Under many circumstances there is a need to exchange user data between terminals or network entities and another data depository. For example, a user may want to replace a terminal with a new terminal without losing personal data, such as contacts and received messages, stored in the original
38、one. The data exchange process might be initiated by the user manually or by a network application automatically, and multiple categories of data might be involved in an exchange process. However, the terminals or entities acting as the source and destination in the exchange process may use differen
39、t operating systems or different internal data expressions for the same kind of data. Without a consistent approach, accurate exchange of the user data is difficult to realize. To facilitate the exchange process and make it as simple as possible for the users, this Recommendation describes an exchan
40、ge approach by using a data package as a container to encapsulate user data and specifies the recommended data syntax for parsing or generating the data package. 7 Scenarios of user data exchange 7.1 User data grouping The user data includes the users personal data, device configuration parameters a
41、nd personalized application data, and can be stored in terminals or other entities, no matter the device type. User data may take various forms such as binary, text or multimedia files depending on the corresponding data category. It could be stored in different locations such as internal memory (RA
42、M, ROM, etc.) and external memory (SIM/USIM, SD card, hard disk, etc.). 7.1.1 Private user data Private user data is created by the user for a special purpose or generated by the users operations and contains important information about the user. Examples of private user data include: Contact inform
43、ation (including phonebook) Messages (including SMS, MMS, IM and e-mail) Calendar information Favourite uniform resource locator (URL) lists and bookmarks Call and browsing history 7.1.2 Device configuration data Device configuration data is the data that a terminal allows users to access and modify
44、, so as to personalize what the terminal displays and the way it behaves. Examples of device configuration data include: Terminal theme, fonts, wallpaper and screensaver Language settings Date/Time and location settings Energy saving settings Accessibility settings 4 Rec. ITU-T F.746.2 (02/2014) 7.1
45、.3 Personalized application data Personalized application data is the data that applications allow users to access and modify, so as to personalize the way an application operates or behaves, including: Service dependent settings or parameters Application settings or application files 7.2 Scenario d
46、escription A basic user data exchange scenario is that a terminal or an entity wants to receive discrete sets of user data from another terminal or to send data to another terminal. For example, a mobile phone desires to retrieve all the contacts and calendar data stored in another terminal. Another
47、 example would be that an entity in the network needs to receive a status report or needs to retrieve the browsing history of the streaming media player on the terminal to use for later statistical purposes. In those cases, typically user data is of small size and may be stored in different formats
48、in the two terminals because of different operating platforms or different data management applications. To exchange data, normally the data providing party will generate a data package which contains multiple categories of data, and the other party receives the data package and performs data analys
49、is, followed by certain operations according to the original purpose of this data acquisition process. 8 User data exchange method 8.1 General procedure For a typical user data exchange scenario, the data exchange process can be summarized into several steps: Export, transfer and analyse. Export: Export selected user data from party A as an accessible data package. Transfer: Party A transfers the selected package to party B by any approach. This step does not need to be in real tim
