Should the TSG modify the contents of the present document, it will be re-rel

21、eased by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit

22、 is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction eCall is a European-wide solution for automatically or manually initiated emergency

23、voice calls. eCall will supplement E112 and 112 (TS12) emergency call with related data from the vehicle, e.g. highly accurate location information. The expected benefit is that emergency services will be made aware of accidents much more rapidly, will get precise information on location, vehicle ty

24、pe etc. and therefore will be able to reach accident victims faster, with the potential to save many lives annually. According to reports from the European Commission, it is envisioned that eCall will be offered on all new vehicles in the EU by 2010. It is expected that the eCall data will be sent e

25、ither during the E112 call set-up or immediately following the establishment of the voice call or at any point later during the voice call. The integrity of the eCall data sent from the vehicle to the Public Safety Access Point has to be ensured. eCall is a European regional requirement. It shall no

26、t have an impact on the global circulation of terminals. ETSI ETSI TR 126 967 V14.0.0 (2017-04)53GPP TR 26.967 version 14.0.0 Release 141 Scope The European Union eCall requirements, recommendations and guidelines were developed by eSafety Forum, with important additional work produced by ETSI MSG,

27、GSME, 3GPP, and CEN. Previous work in 3GPP TR 22.967 2 Transfer of Emergency Call Data, examined the issues associated with the transmission of emergency call data from a vehicle to a PSAP. This analysis identified that the preferred option be based on an in-band modem solution. The objective of thi

28、s work was to examine and describe the in band modem solution (in band modem and any necessary interface to the ME) for eCall. Because eCall is a European regional requirement, it shall not have an impact on the global circulation of terminals. In the interest of not duplicating work, the set of in-

29、band solutions that were considered are those preferred by GSME unless significant improvements are available. The work assessed the suitability of existing 3GPP in-band solutions, e.g. CTM, to satisfy the requirements for eCall. The present document assesses the suitability of CTM for eCall. 2 Refe

39、es the suitability of the existing “Cellular Text telephony MODEM“ (CTM) for the transmission of eCall data via the voice channel from the “In-Vehicle System“ (IVS) to the “Public Safety Answering Point“ (PSAP). Chapter 5 reprints the service requirements for the eCall transmission, as specified in

40、TS 22.101, for convenience. Chapter 6 assesses point by point these requirements against the performance of the eCall transmission via CTM as outlined in the Annexes A, B, C. Chapter 7 provides the Conclusions. The following annexes are also included: Annex A gives a brief description of CTM with re

41、spect to its application for eCall. Annex B outlines one possible protocol that utilizes CTM for the secured transmission of the eCall data through the voice channel. Annex C reports the analysis for eCall via CTM, under the condition that the outlined protocol is used. Annex D discusses the archite

42、cture for eCall in the vehicle in order to identify the interface to the UE and to analyze potential open issues. Annex E gives examples of network architectures today and in future and discusses VoIP and the future All-IP scenarios. Also the co-existence of eCall and Global Text Telephony is descri

43、bed here. Annex F discusses potential Optimizations for CTM and for the proposed eCall Protocol. ETSI ETSI TR 126 967 V14.0.0 (2017-04)73GPP TR 26.967 version 14.0.0 Release 145 eCall MSD data transmission requirements Based on input from external sources, like EC, eSafety and ETSI-MSG, 3GPP has dev

44、eloped a set of requirements for the in-band modem solution for eCall, see TS 22.101 1. Begin of Extract from TS 22.101 (V8.6.0) 1: TS 22.101, Clause 10.7 “Transfer of data during emergency calls“ Emergency calls may be supplemented with emergency related data 1. Typically this data enables the accu

45、rate geographic location of a manually or automatically activated emergency calling device e.g. an in vehicle system (IVS), to be provided to the Public Safety Answering Point (PSAP). - The data may be sent prior to, in parallel with, or at the start of the voice component of an emergency call. - Sh

46、ould the PSAP request additional data then this may be possible during the established emergency call. - The realisation of the transfer of data during an emergency call shall minimise changes to the originating and transit networks. - Both the voice and data components of the emergency call shall b

47、e routed to the same PSAP or designated emergency call centre. - The transmission of the data shall be acknowledged and if necessary data shall be retransmitted. - A UE configured only to transfer data during emergency calls (e.g. eCall only UE) shall not generate signalling to the network besides w

48、hat is needed to place an emergency call. Additional national and regional requirements are as specified in annex A TS 22.101, Annex A.27 “Requirements for the transfer of eCall Minimum Set of Data (MSD)“ With the exception of the following specific requirements, considered necessary for the satisfa

49、ctory operation of the eCall service, all existing TS12 emergency call requirements shall apply. An eCall shall consist of a TS12 emergency call supplemented by a minimum set of emergency related data (MSD). The contents of the MSD e.g. vehicle identity, location information and other parameters, are defined by CEN/TC 278 WI 24977. - An eCall may be initiated automatically, for example due to a vehicle collision, or manually by the vehicle occupants. - The Minimum Set of Data (MSD) sent by the In vehicle System (IVS) to the network sh
