Forewor

29、d This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction The present document has been produced by an ETSI STF co-funded by EC/EFTA to examine the work of various

30、Standards Development Organizations worldwide in developing and implementing protocols for the transmission of location information over telecommunications networks for use in establishing the location of users of the emergency calling facilities. In order to effectively deliver emergency services t

31、o the location of a reported incident, it is essential for the emergency response organization to have timely and accurate information that enables them to correctly identify the location of the incident. The ability to initiate an emergency communication to summon help when needed is regarded by th

32、e European Commission as a right of all citizens and this ability should ideally be independent of the network and access technologies deployed or the physical abilities of the citizen. The rights of individual users to privacy shall be adhered to according to European regulations and it is therefor

33、e essential that all information derived from emergency calls shall only be used for management of the related incident. If applied to non-emergency calls, the use of caller location information for commercial purposes may also be subject to European or national regulation. In many circumstances, ci

34、tizens reporting an incident requiring urgent assistance are unable to provide the emergency service with accurate information about the location of the emergency. This may be due either due to the nature of the emergency, the callers lack of local knowledge, their disabilities or lack of linguistic

35、 ability, etc. Young children or cognitively impaired people may not have the language skills to explain their location, speech and/or hearing impaired users may not be able to use voice terminals, visually impaired or otherwise disabled people may not be able to use text terminals, elderly or confu

36、sed people may not be able to use any form of terminal, etc. For these significantly large categories of users the successful outcome of an emergency call could make the difference between life and death. It is therefore essential for the emergency responders to be provided with accurate location in

37、formation via an automated process based on the communications network being used by the caller. Implementation of caller location systems is also likely to result a welcome positive impact on the reduction of malicious calls made by criminal or anti-social persons when they realize that the automat

38、ic provision of their location information to the emergency services could enable their almost instant apprehension. The present document should be read in conjunction with TS 102 660 19 which reports on the Signalling Requirements and Signalling Architecture for Supporting the Various Location Info

39、rmation Protocols for Emergency Service on a NGN. The object of this work was to determine what, if any, standards existed and had been adopted for signalling details of an emergency callers location, in order to assist in the response to emergency calls. It should be recognized that in the present

40、document all references implying that 911 is the common emergency calling number are used only to identify pre-existing work and as part of the titles of other documents. The mandated common European emergency number is 112 with many countries also operating national numbers in parallel. ETSI ETSI T

41、S 102 650 V1.1.1 (2008-07) 7 The present document does not contain a fully detailed technical analysis of location information standards but concentrates on the background information and the ongoing activities by the various standards bodies in different regions. It should be borne in mind that the

42、 document is intended to be focussed on what EC/EFTA wanted from their contract, essentially to understand what the work is and what needs to be done. It is for TISPAN to do the in depth analysis and produce the detailed technical recommendations. ETSI ETSI TS 102 650 V1.1.1 (2008-07) 8 1 Scope The

43、present document represents an analysis of the work done by various ETSI work groups and other standards bodies worldwide on the acquisition and transmission of caller location information in various communications network types. It also contains information about the protocols used and of any known

44、 deployments for the location of users making emergency calls. It is not intended to examine the detailed workings of the protocols described or their possible use in other communications network types. The document does not mandate any new requirements but does report on the normative requirements

45、from other standards and regulatory bodies. It also refers, in part, to operating methods and national regulations in various jurisdictions but does not intend to endorse these as requirements. The hypothetical accuracy of the caller location and the accuracy achieved by the assessing methods are al

46、so documented. Alternative methods for the coding of the emergency location information are also examined. The present document also indicates a number of scenarios where location information may not be available or may be inaccurate to various degrees and may suggest solutions for improvement. 2 Re
