ITU-T Q.3905 (02/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and co

11、mmunication technologies (ICTs). The 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.

12、 The World Telecommunication Standardization 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 Resoluti

13、on 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 In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and

14、 a recognized operating agency. Compliance 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 me

15、t. 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 suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibi

16、lity that the practice or implementation 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 Rec

17、ommendation development process. As of 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. However, implementers are cautioned that this may not represent the latest informati

29、to whom the number is ported. 3.1.10 routing number: A number that is derived and used by the network to route the call towards a ported number. 2 Rec.

35、 scenarios for implementing number portability. In accordance with the functionality, there are two groups of service scenarios: The first group is based on the method “all call query“; The second is based on the method “onward routing“. The first scenario deals with the originating network/exchange

36、 which is not connected directly to number portability database (NPDB). In this case, the originating network/exchange forwards a request to the initiating network/exchange to obtain routing information. The second scenario is based on the fact that the initiating network/exchange also plays the rol

37、e of the originating network/exchange of the calling subscriber. In this scenario, the request for routing information has to be sent to the number portability central database (NPCDB) through the donor network/exchange. In the third scenario donor network/exchange acts as an initiating network/exch

38、ange and requests the routing information in their number portability local database (NPLDB). The first and second scenarios belong to the first group which is related to “all call query“, while the third scenario belongs to the second group which is related to “onward routing“. Accordingly, the sig
