The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. S
21、hould the TSG modify the contents of the present document, it will be re-released 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 grea
22、ter indicates TSG approved document under change control. y the second digit 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
23、 a European-wide solution for automatically or manually initiated emergency 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 accid
24、ents much more rapidly, will get precise information on location, vehicle type 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 v
25、ehicles in the EU by 2010. It is expected that the eCall data will be sent either 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 Po
26、int has to be ensured. eCall is a European regional requirement. It shall not have an impact on the global circulation of terminals. ETSI ETSI TR 126 967 V13.0.0 (2016-01)53GPP TR 26.967 version 13.0.0 Release 131 Scope The European Union eCall requirements, recommendations and guidelines were devel
27、oped by eSafety Forum, with important additional work produced by ETSI MSG, 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 th
28、e preferred option be based on an in-band modem solution. The objective of this 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 cir
29、culation of terminals. In the interest of not duplicating work, the set of in-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
30、 eCall. The present document assesses the suitability of CTM for eCall. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

39、Identity Module 4 Outline of the present document The present document analyses 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 r
40、eprints the service requirements for the eCall transmission, as specified in 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 followin
41、g annexes are also included: Annex A gives a brief description of CTM with respect 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 th
42、e condition that the outlined protocol is used. Annex D discusses the architecture 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
43、scenarios. Also the co-existence of eCall and Global Text Telephony is described here. Annex F discusses potential Optimizations for CTM and for the proposed eCall Protocol.

44、d on input from external sources, like EC, eSafety and ETSI-MSG, 3GPP has developed 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 sup
45、plemented with emergency related data 1. Typically this data enables the accurate 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 par
46、allel with, or at the start of the voice component of an emergency call. - Should 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
47、 networks. - Both the voice and data components of the emergency call shall be 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 call
48、s (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
49、 of the following specific requirements, considered necessary for the satisfactory 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 Mini
