Freddie McBride, European Communications Office eCall – Implementation challenges Freddie McBride, European Communications Office ETSI NTECH #18 Sophia Antipolis 26-28 April 2017

eCall Workshop – 31 January 2017, ECO Copenhagen Attended by stakeholders from all relevant groups (OEMs, Operators, PSAPs, SDOs and Regulators) Presentations from stakeholders on market trends, implementation, interoperability, numbering and next-generation eCall Good discussions but more questions than answers on implementation NTECH should be aware of the implementation challenges and possible impacts on standards ECC Recommendation – Numbering for eCall - 2017

About CEPT, ECC and ECO

What is eCall eCall is a European initiative intended to bring rapid assistance to motorists involved in a collision anywhere in the European Union Source: Wireless Design & Development eCall is a 112 call. Requirements for citizen access to 112 and the provision of caller location information apply

eCall Legislative Requirements Source: SBD/Vodafone

eCall Penetration eCall regulation applies to ‘new type’ vehicles Model cycle typically 4-6 years

eCall + value-added services Source: Cubic Telecom

eCall only V. TPS eCall + VAS Mandatory pan-European eCall a citizen protection policy initiative There is no business opportunity in eCall alone. “all vehicles should be equipped with the public 112-based eCall service, regardless of whether or not a vehicle owner opts for a TPS eCall service.” - REGULATION (EU) 2015/758 Source: EENA

eCall Profile Characteristics eCall-only profile Dormant – no mobility management Privacy by design No subscription eCall+VAS profile Always connected Subscription-based service Privacy right waived in subscription agreement Only one profile can be active at any given time!!

eCall numbering requirements Why do we need numbers in the first place? eCall is essentially a mobile service eCall needs wide geographic coverage and the ability to roam between networks Emergency calls from “simless” devices not supported in a lot of European Countries For network authentication and registration (including roaming) each eCall in-vehicle system needs an International Mobile Subscriber Identity Number (IMSI) Each eCall in-vehicle system needs an telephone number (or MS-ISDN or E.164 number) to be able to make a call and present a valid CLI. A valid CLI is needed to facilitate callback/location update

Emergency Attach to Mobile Network Each eCall device will have a subscription and an E.164 number If the SIM is dormant, will it perform an “emergency attach” to make a call? If it does, a temporary number is assigned and the original E.164 is irrelevant How can callback be facilitated? Will the temporary number be sent in the CLI field? How long will the temporary number remain assigned*? CEN EN16072 standard says "minimum period of one hour after the eCall is terminated or until available power is exhausted" and 3GPP says 12 hours. ETSI TS 103 412(http://www.etsi.org/deliver/etsi_ts/103400_103499/103412/01.01.01_60/ts_103412v010101p.pdf) - Mobile Standards Group (MSG); Pan-European eCall end to end and in-band modem conformance testing; Prose test specification

PSAP Operator View (Lithuania 112)

What deployment might look like – embedded eUICC This is my view on how eCall will be deployed.

What deployment will look like – cont’d

eCall technology – now and future eCall as required by legislation uses circuit-switched technology on GSM/UMTS (CS eCall) (standardisation began in 2004) eCall device has inband modem (voice and date carried on same channel) PSAPs need to install inband modems to process MSD Next Generation eCall (NG eCall) will be based on IMS (standardisation began in 2013) Vehicles could be fitted soon with devices capable of supporting both technologies At this point there is no option for PSAPs to future proof investments Remember average age of a car on European Roads is around 18 years in some parts of Eastern Europe

Telephone (E.164) Numbers for eCall How many numbers required? 270 million vehicles – approx 5% stock renewal each year (13.5 million) New passenger car registrations in Europe (source: ACEA) Demand for approximately 13,000,000 new mobile telephone numbers per annum when critical mass of new type vehicles reached (so not anytime soon!) Numbering Options National numbers (assigned by National authorities) Dedicated M2M numbers Mobile numbers International numbering resources (Assigned by ITU-T) +882, +883, +878 number ranges Year 2012 2013 2014 2015 2016 5 yr average New registrations (000,000) 12 11,9 12,5 13,7 14.6 12,9

eCall Life Cycle Management Link between VIN and SIM Beginning: Deals between OEMS and MNOs Deployment at car assembly plant Middle Accidents & Testing (mandatory periodical inspections) End Car written/off or reaches end of life naturally Decommissioning of SIM Recover of numbering resources

Standards – NG eCall NG eCall Standardization Status ETSI / 3GPP TR 103 140 recommends to use 3GPP and IETF for eCall – published in 2014 Emergency call requirements for IMS – stable IMS eCall requirements and migration from CS eCall – stable IETF ‘eCall’ RFC–publication – latest version dated February 2017 Focuses on next generation eCall specific needs for the EU Carries data and metadata/control objects per ‘additional-data’ mechanism Metadata/control (ack, retransmission, requests to vehicle, etc.) additional-data' specification (RFC 7852) - published Transmit any registered data block with emergency call CEN eCall over IMS (TC278 WG15, PT1506) – draft available, approval expected Q1 2017 eCall to other classes of user (PT1507) – started eCall over a common telematics platform (PT1508) – started Footer copy here

Areas where other standardisation work may be necessary Over-the-air Provisioning of subscriber profiles GSMA Specification ETSI Standard (TC SCP) Temporary assignment of MS-ISDNs (if eCall SIMs dormant) Need for defining minimum period of time for which number remains assigned (days not hours according to PSAPs) TPS eCall Define a standard approach for conveying an emergency call from a TPS eCall centre to a PSAP At ITU level Raising awareness and encourage provisioning of global numbering resources on all networks
