The IT-T is responsible for studying technical, operating a
3、nd tariff questions and issuing Recommen- dations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn
4、, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). ITU-T Recommendation F.851 was prepared by ITU-T Study Group 1 (1993-1996) and was approved under the WT
5、SC Resolution No. 1 procedure on the 21st of February 1995. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

11、l Telecommunication (UPT). It describes the main principles of UP”, for example personai mobility, authentication and service profile management. It defines the UPT service aspects from the users perspective (e.g. numbering and charging aspects). It also describes the essential features necessary to
12、 provide the UPT service, and the optional features which may be used to support additional enhancements. UPT Service Set 1 is a restricted scenario that provides UPT service that supports provision of telephone service over PSTN, ISDN and PLMN networks. UPT Service Set 2 is currently under discussi
13、on, and represents a more enhanced scenario with more features and capabilities (e.g. support of data services). 11 Recommendation F.851 (OY95) ITU-T RECMN*F.5L 95 4862.59L Ob00330 827 Recommendation F.851 UNIVERSAL PERSONAL TELECOMMUNICATION (UPT) - SERVICE DESCRIPTION (SERVICE SET 1) (Geneva, 1994
14、) 1 General 1.1 Scope This Recommendation is intended to provide the service description and operational provisions for Universal Personal Telecommunication (UPT). Following the principles laid down in Recommendation F.850, “Principles of UPT”, this Recommendation provides the general service descri
15、ption from the point of view of the individual UPT subscriber or UPT user. It does not consider network implementation or regulatory issues. For the purpose of this Recommendation, the term UPT Service(s) describes the offering of a combination of network capabilities together with the appropriate u
16、ser-network interface facilities which enable each UPT user to participate in a user-defined set of subscribed services. This offering may vary according to the scope of such capabilities that the service provider may wish to offer. 1.2 General description UPT introduces the concept of UFT number. I
17、n fixed telecommunication networks, a user or subscriber is associated with the network access point of the terminal, the point of attachment of the terminal. In certain mobile telecommunication networks, a user or subscriber is associated with the specific terminal in use. In the UPT environment, t
18、he fixed association between terminal and user identification is removed. In order to offer users the capability of establishing and receiving calls on any terminal and at any location, the identification of UPT users is treated separately from the addressing of terminals and network access points.
19、UPT user identification is achieved by means of a UPT number. The UPT user is therefore personally associated with his or her own UPT number, which is used as the basis for making and receiving calls. The UPT number is diallable on a global basis and routable from any fixed or mobile terminal, acros
20、s multiple networks irrespective of geographical location, limited only by the terminal and network capabilities and any restrictions imposed by the network operator. The UPT user may be assigned one or more UPT numbers. UPT also allows the UPT user to participate in a user-defined set of subscribed
21、 services, from amongst which the user defines personal requirements, to form a UPT service profile. The following summary of both, short-term and long-term UPT objectives include: UPT service profile A personalized UPT service profile which contains a list of services and facilities subscribed to b
22、y the UPT subscriber, and a range of options. Personal numbering A UPT number, which uniquely identifies each UPT user and is used by the caller to reach that UPT user. A UPT user may have more than one UPT number for different applications (for example, a business UPT number for business calls and
23、a private UPT number for private calls). Personal charging Charging, which is associated with the UPT number rather than with any terminal or network used by the UPT user. Simple billing Preferably, a UPT subscriber will only receive bills from one UPT service provider even though UPT facilities may
24、 have been used in different networks, in different countries and using different network operators. Recommendation F.851 (OU95) 1 ITU-T RECMN*F.853 95 m 4862593 Ob00333 763 , Terminal independence Telecommunication services are provided to the UPT user, independent of the terminal used. The termina
25、l, if capable of providing the services requested by the UPT user, will make them available to the UPT user. Security and privacy The UPT user may use the UPT service with minimal risk of violated privacy or erroneous charging due to fraudulent use. Automation of user interaction with the UPT servic
26、e The UPT users may make use of means to facilitate and automate their interactions with the UPT service. Access from multiple networks The UPT service may be used across multiple networks (e.g. PSTN, ISDN, PLMN, PDNs etc.) using the same UPT number. The serving network, if capable of supporting the
27、 services requested by the UPT user, may make them available to the UPT user. UPT may also operate over private networks if the private networks agree to UPT interworking with the public network. Universal service availability In principle, any basic telecommunications service can be used with the U
28、PT service. The services provided to the UPT user are only limited by the networks and terminals used. Dynamic registration of terminal address The UPT user may dynamically and independently register with the terminal addresses at which he will make or receive calls. The registered terminal addresse
29、s may differ from service to service. Subscription involving multiple UPT users One UPT subscriber may be responsible for more than one UPT user, each having a personal UPT number and an associated UPT service profile (e.g. a company having a set of employees). Privacy for third parties Third party
30、users (e.g. terminal owners) will in principle, not suffer in terms of privacy or freedom of actions as a result of UPT activities by UPT users. Early implementations of UPT may not be able to realize all these objectives. Provision of UPT services is expected to commence with a simplified set of es
31、sential and optional UPT features and capabilities, which will evolve into more advanced scenarios. Evolution of UPT is described in 2.1. 1.3 Definitions and terminology The following definitions of UPT terms used throughout this Recommendation are consistent with the abbreviated definitions in Reco
32、mmendation I. 1 14 “Vocabulary of Terms for Universal Personal Telecommunication”. 1.3.1 authentication: A process by which the verification of the UPT user identity is accomplished. 1.3.2 call: In the UPT context, “call” is used to indicate telephony, data, facsimile, ISDN, B-ISDN, etc. calls. 1.3.
33、3 determine the distance-related charges applying to the calling party andor called UPT user. charging reference location: The geographical location that may be used by the UPT service providers to 1.3.4 identification: A process to identify the UPT user or the UPT service provider. 1.3.5 network li
34、mitations: The UPT-serving (or UPT-supporting) network should provide a UPT user with access to all services delineated in the UPT users personal UPT service profile. However, the serving network may not be capable of providing, or may choose not to provide, all such services for reasons which may i
35、nclude coverage limitations, regulatory restrictions and domestic or international safety or other requirements. 2 Recommendation F.851 (02/95) 1.3.6 personal mobility: The ability of a user to access telecommunication services at any terminal on the basis of a personal identifier (e.g. the UPT numb
36、er), and the capability of the network to provide those services delineated in the users service profile. Personal mobility involves the network capability to locate the terminal associated with the user for the purposes of addressing, routing and charging of the UPT users calls. 1.3.7 terminal addr
37、ess: A number used to identify a unique terminal or fixed network access point on a network. 1.3.8 personal UPT service profile is only limited by the capabilities that the terminal attached to the network can support. terminai limitation: A UPT user accessing a network that is providing the full se
38、rvices of the UPT users 1.3.9 while in motion, and the capability of the network to identify and locate that terminal. terminal mobility: The ability of the terminal to access telecommunication services from different locations 1.3.10 UPT (Universal Personal Telecommunication): UPT enables access to
39、 telecommunication services while allowing personal mobility. It enables each UPT user to participate in a user-defined set of subscribed services and to initiate and receive calls on the basis of a personal, network-transparent UPT number across multiple networks on any fixed or mobile terminal, ir
40、respective of geographical location, limited only by terminal and network capabilities and restrictions imposed by the network operator. 1.3.11 to enter the UPT environment before any UPT procedures can be carried out. UPT access code: A code the UPT users may need to dial, when using certain termin
41、als and networks, in order 1.3.12 UPT environment: The environment within which the facilities of the UPT service are offered. It consists of combinations of networks and UPT service control facilities, which when combined, enable the UPT user to make use of the telecommunication services offered by
42、 these networks. To the UPT user, the UPT environment appears as one global network which provides personal mobility. However, when making use of telecommunication services, the UPT user may be limited by restrictions imposed by the network, by the capabilities of the terminals and networks used, or
43、 by regulatory requirements. 1.3.13 UPT number: A number that uniquely identifies a UPT user; it is also used by a calling party to reach that UPT user. A UPT user may have more than one UPT number (for example, a business UPT number for business calls and a private UPT number for private calls). 1.
44、3.14 to ensure that the UPT user is able to make or receive calls. UPT procedures: UPT procedures, as seen by the UPT user, are procedures that must be carried out in order 1.3.15 in order to provide that user with the UPT service. Each UPT service profile is associated with a single WT number. UPT
45、service profie: The UPT service profile is a record containing all the information related to a UPT user 1.3.16 UPT service profile management: The capability to access, interrogate and modify the UPT service profile. 1.3.17 UPT. The service provider will make the arrangements necessary for the prov
46、ision of such facilities. UPT service provider: A service provider, to which a UPT user must subscribe for use of the facilities of 1.3.18 UPT subscriber: A person or legal entity having specifically subscribed to a UPT service provider for UPT services to be used by one or more UPT users. The subsc
47、riber defines, and may modify, the limits within which such users can modify their personal service profile. The subscriber is responsible for payment of the charges due to that service provider. The UPT subscriber may also be the UPT user. 1.3.19 numbers. The UPT user may also be the UPT subscriber
48、. UPT user: A person or entity having access to UPT services and having been assigned one or more UPT 1.3.20 UPT user group: A specific set of UPT users. Recommendation F.851 (02195) 3 ITU-T RECMN*F.853 75 4862573 Ob00333 536 W 2 Basic considerations 2.1 Evolution of UPT UPT is expected to materiali
49、ze over a period of time and will experience an evolutionary path that is heavily impacted by evolving market needs and advances in technology. Provision of the UPT service will start with a simplified set of essential and optional UPT features and capabilities and progress into more advanced scenarios. Standardization of UPT may therefore be split into three general phases. 2.1.1 UPT Service Set 1 - Restricted short-term UPT service scenario In this scenario, available network capabilities may result in restrictions on the level of services, security and user- friendly features that ca
