6、efinition Summary Given the rapid multiplication and expansion of telecommunication services, there is a growing need for subscribers to those telecommunications services to be able to communicate with each other. In order to facilitate such intercommunications for the subscribers of the various ser
7、vices, operator assisted and public Directory Services will be required. The Service Definition in this Recommendation supports the provision of those Directory Services. Source ITU-T Recommendation F.510 was revised by ITU-T Study Group 17 (2001-2004) and approved under the WTSA Resolution 1 proced
8、ure on 13 February 2003. ii ITU-T Rec. F.510 (02/2003) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for
9、studying 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
10、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 technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis wi
11、th 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. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this
12、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 of the date o
13、f approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult th

F.510 (02/2003) v Introduction This Recommendation details a service definition for the provision of electronic acce
20、ss to an International number information service by cooperating ROAs. This service is suitable for use both by the operators of ROAs providing a DQ service to their customers, and by direct access of authorized customers. The service addresses not only the provision of fixed-line telephone numbers,
21、 but also the provision of the number information of other communications media facsimile, mobile, videotelephony, etc. The service can also provide other communications address information such as electronic mail and application process addresses. The service definition meets the current and forese
22、eable future needs of the service and is designed for worldwide use if required. The service definition provides the basis for the progressive delivery of a constantly improving DQ service. The definition allows for the functional capabilities of systems (all or individual) to be expanded, and conti
23、nually evolved, within but not limited to the constraints set by the definition. The service definition enables, and should encourage, the implementation of cooperative systems through which an efficient International DQ service is provided. The service includes, but is significantly different from
24、that defined by ITU-T Rec. E.115, in that it defines services for both operators, end-users and processes, provides telecommunications addresses in addition to telephone numbers. ITU-T Rec. F.510 (02/2003) 1 ITU-T Recommendation F.510 Automated directory assistance White pages service definition 1 S
25、cope This service definition is the basis for the establishment of a truly International DQ service through the standardized interworking of numerous individual DQ information services. This service definition provides a general framework for the provision of electronic access to international Direc
26、tory Services. It defines the requirements for, and the service features associated with the provision of such Directory Services. It specifies the requirements to support Directory Services that may be offered to both Directory Service operators and to end-users. It encompasses the operational aspe
27、cts of the service and includes Quality of Service and Charging and Accounting. This service definition defines the White Pages Directory Service. However, the services and elements specified herein may be used to define other services, such as Yellow Pages. A DQ service might have more than one acc
28、ess point available for retrieving information from another country. At each of these access points information might be retrieved from one or more national service or information providers. There may be various types and levels of service quality provided. This service definition does not define an
29、y mechanism for selection of provider and of any explicit mechanism for selection of quality of service. This service definition assumes that information is retrieved from a single country at a time. The name of the country must be included in the request parameters. Removal of the single country re
30、striction is for further study. This service definition does not specify the method of implementation which may use any appropriate protocols (or combination of protocols). The terms used in this Recommendation adopt their conventional meaning (dictionary definition), and the meaning of terms, such
31、as “attribute“, should not be assumed from other (standards) documents in which they may be defined. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

38、ation held within a directory associated with, and for the purpose of identifying, a communications address, as described in 7.5.2. 3.1.2 directory entry: Information associated with a particular type of real world object. An object consists of one or more attributes. This Recommendation defines the
39、 objects and the information required to support the service. 3.1.3 attribute: An attribute has a type and a value. A particular attribute type may be used in one or more directory entries. A new attribute may also be formed by the combination of (simpler) attribute types. 3.1.4 key attribute: An at
40、tribute parameter in a search request that is required to match a real-world attribute, e.g., a locality, but not to be ambiguous to a level determined by local considerations. 3.1.5 service provider: A Service Provider is the function, supported by an ROA, that supplies a Directory Service to one o
41、r more Query Service Agents. 3.1.6 query service agent: The Query Service Agent issues physical search requests to and receives responses from one or more Service Providers. The Query Service Agent may perform Service Provider selection, query modification (or rejection) on the basis of knowledge of
42、 the Directory Services offered by Service Providers to which it has access. 3.1.7 directory service: A Directory Service is a service which supports the following functionalities. 1) Standardization of directory objects and attributes and their interpretation and utilization. 2) Defined Directory I
43、nformation. 3) Unambiguous definition of the enquiries that have to be supported by the Service Providers. 4) Resilience to requests specifying search attributes and matching types which are not supported by the Service Provider. 5) Means of communicating to the Directory Service user what is requir
44、ed in order to fulfil request, i.e., definition of services on offer. 6) Defined matching rules and character sets, including its conversion and interpretation rules. 7) Defined handling of language translation. 8) Ordering of returned entries. 9) Definition of information returned for unsuccessful
45、or failed searches. ITU-T Rec.
