10、endation ITU-T E.161.1 Guidelines to select Emergency Number for public telecommunications networks Summary The purpose of Recommendation ITU-T E.161.1 is to provide guidance to help Member States who are in the process of selecting a single emergency number for the first time, or selecting a second

11、ary alternative emergency number for public telecommunications networks. Source Recommendation ITU-T E.161.1 was approved on 23 September 2008 by ITU-T Study Group 2 (2005-2008) under the WTSA Resolution 1 procedure. ii Rec. ITU-T E.161.1 (09/2008) FOREWORD The International Telecommunication Union

12、(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, operating and tariff questions and

13、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 turn, produce Recommendations on these

14、 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 In this Recommendation, the expres

15、sion “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.g., interoperability or applicabili

16、ty) 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 suggest that compliance with the Rec

17、ommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility 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

18、of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation 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

19、 Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

22、s intended for use by Member States who are in the process of selecting: a) a single emergency number for the first time b) a secondary alternative emergency number. Either emergency number will be made available to users and subscribers, and therefore the mapping of these numbers to technology requ

23、irements is considered out of scope of this Recommendation. In the long run, this Recommendation will contribute to globally harmonized emergency numbers. 2 References None. 3 Definitions 3.1 Terms defined elsewhere This Recommendation uses the following terms defined elsewhere: 3.1.1 emergency call

24、 b-ITU-T Q-Sup.47: A call requesting emergency services. A caller is given a fast and easy means of giving information about an emergency situation to the appropriate emergency organization (e.g., fire department, police, ambulance). Emergency calls will be routed to the emergency services in accord

25、ance with national regulations. 3.1.2 country b-ITU-T E.164-Sup.3: A specific country, a group of countries in an integrated numbering plan or a specific geographical area. 3.1.3 universal subscriber identity module (USIM) b-3GPP TR 21.905: An application residing on the UICC used for accessing serv

26、ices provided by mobile networks, which the application is able to register on with the appropriate security. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 emergency number: A non-E.164 number allocated in the national numbering plan to enable emerge

27、ncy calls. Normally, the emergency number is a short code. 3.2.2 short code: String of digits in the national numbering plan, as defined by the national Numbering Plan Administrator which can be used as a complete dialling sequence on public networks to access a specific type of service/network. The

28、 short code is referred to as a non-E.164 number, and its length is normally shorter than a subscriber number. 2 Rec.

30、te that is planning to introduce an emergency number could use either 112 or 911, in adherence with applicable regulations concerning emergency numbers (e.g., the usage of 112 for EU Member States b-EU 91/396/ECC). 6 Selection of a second alternative Emergency Number A Member State that is planning

31、to introduce a second alternative emergency number could use either 112 or 911, or both, which should be routed to the existing emergency number. A second alternative emergency number facilitates, for example, emergency calling by travellers visiting the country. 7 Emergency Numbers for mobile netwo

32、rks This clause give examples of how emergency numbers are used in terminals and identity module cards (e.g., SIM) for different kinds of mobile networks (PLMNs). 7.1 PLMNs based on GSM/UMTS system For mobile equipment (ME) based on the GSM/UMTS system, there is a built-in recognition of the emergen

33、cy numbers 112 and 911. If the SIM/USIM/ISIM card is not present in the ME, then, in addition to 112 and 911, the following national numbers will act in a similar way as national emergency numbers: 000, 08, 110, 999, 118 and 119 b-3GPP TS 22.101. It will be left to the Member State to decide whether

34、 the public telecommunications network accept emergency calls without the SIM/USIM/ISIM. Rec.
