Introduction eCall is a European-wide solution for automatically or manually initiated emergency voice calls. eCall will supplement E112 and 112 (TS12) em
25、ergency 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 type etc. and therefore will be able to reach accident vict
26、ims 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 either during the E112 call set-up or immediately followin
27、g 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 not have an impact on the global circulation of terminals.
28、ETSI ETSI TR 126 967 V15.0.0 (2018-07)53GPP TR 26.967 version 15.0.0 Release 151 Scope The European Union eCall requirements, recommendations and guidelines were developed by eSafety Forum, with important additional work produced by ETSI MSG, GSME, 3GPP, and CEN. Previous work in 3GPP TR 22.967 2 Tr
29、ansfer 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 this work was to examine and describe the in band modem solu
30、tion (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-band solutions that were considered are those preferred b
31、y 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 References The following documents contain provisions which,

41、elephony 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 TS 22.101, for convenience. Chapter 6 assesses poin
42、t 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 respect to its application for eCall. Annex B outline
43、s 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 architecture for eCall in the vehicle in order to identify
44、 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 described here. Annex F discusses potential Optimizations
45、 for CTM and for the proposed eCall Protocol.

46、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 accurate geographic location of a manually or automatic
47、ally 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. - Should the PSAP request additional data then this may
48、 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 be routed to the same PSAP or designated emergency c
49、all 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 what 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 satis
