Alternately, it might use the ACN procedures to establish the primary video channel appropriate to ACN. (...) Alternately, we could adopt a simple convention where ACN is always used for Fallback in cases where both terminals support the combination of ACN and Fast Media. (...) To solve this, we propose to add explicit signaling of the Mux Codes that an FM + ACN terminal intends to use for primary audio and visual channels negotiated under ACN.

If both terminals support ACN, they shall assume that the ACN procedure is used in that call. (...) The moment a terminal using ACN in an ACN-enabled call knows who the master is and who the slave is of the call it can start sending media. (...) The master terminal shall open a bidirectional video channel using ACN if it indicated it using the masterBidirectionalVideo parameter, and shall open a unidirectional video channel using ACN otherwise.

ACN can also be combined with WNSRP to get the usual benefits. (...) Specifically, a non-ACN terminal receiving an H.245 TCS including the ACN extensions will simply ignore them. At the same time, the non-ACN TCS sent in the opposite direction will serve as indication to the ACN terminal that the remote terminal does not support ACN.

s4-horncastle International Telecommunication Union “The Fully Networked Car, A Workshop on ICT in Vehicles” ITU-T Geneva, 2-4 March 2005 EE--call and Automatic Crash call and Automatic Crash Notification (ACN) in Notification (ACN) in vehiclesvehicles David Horncastle European Coordinator, YGOMI LLC 2 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 In the Vehicle, the Service that the Consumer Really Wants … o Delivers reliable, immediate emergency assistance after a crash o Provides peace of mind, safety, and security o Has no subscription complexity and no monthly or annual fee o Is provided for the life of the vehicle as part of the vehicle purchase 3 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 Telematics Today o Current Emergency Call offers are bound up with many of the issues facing the market generally • Much of today's telematics has poor business models • High costs – Complexity - Low customer value …as a result, many offerings have not met customer expectations or volume & financial projections o In addition, there are concerns about • Offering safety systems such as Automatic Crash Notification (ACN) that stop working if the vehicle owner does not make continuing payments • Confidentiality of customer relationships and critical vehicle data, which is not secure over the current telematics communications pathways 4 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 Land Side Platform (LSP) Concept o A cooperative effort by several vehicle manufacturers to develop a new, more responsive vehicle data communications architecture • That meets their needs and interests and the needs of the purchasers of their vehicles • Built to provide opportunities for information and services providers to operate profitably • Structured to become a utility controlled by vehicle manufacturers, not a business selling a product o Ygomi LLC is coordinating the development of the LSP concept ...and is supporting the LSP Automotive Group, which guides this development 5 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 LSP and Vehicle Safety o The LSP concept is structured around support for safety: • A robust, reliable facility to route emergency data messages • Including the ability to handle multiple makes/models/years via protocol converters • Eventual support for probe (or ‘floating car’) messages to/from vehicles • ...but other (non-safety) types of messages handled as well o Cost for provision of a lifetime ACN facility would be included in the purchase price of the vehicle 6 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 ‘Traditional’ In-Vehicle E-call o An emergency wireless voice call that includes vehicle location o Introduced by vehicle manufacturers in the 1990s as the initial telematics service o Originally available only as a vehicle-based product • Generally using a telematics service provider as an intermediary between vehicles and PSAPs • Offered as a paid subscription service requiring periodic renewals and payments o Recurring cost and lack of perceived value for the overall telematics service has resulted in • Many people not renewing the service • The vehicle equipment becoming redundant 7 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 E-112/E-911 is Coming… o From ~2006 all mobile phone emergency calls will include positioning as part of E-112/E-911 • Emergency voice calls from all phones will go to the PSAP with location information • Dramatically reduces the value of separate voice-based vehicle service to provide position o New intermediary to PSAPs may be a ‘pre-help’ service for language assistance, special medical situations, etc. • Useful from any phone (wired, wireless, internet) • Any phone could be set to autodial this service • Could be operated by auto clubs, insurance providers, communications carriers, etc. 8 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 In-Vehicle Considerations o Some vehicle manufacturers will provide a ‘manual’ SOS button in the vehicle • Initiates a voice E-112/E-911 call from all capable phones in the vehicle • Possible option: Allow the vehicle manufacturer or owner to set the SOS button to dial a pre-help service • Mobile phones may include such a capability o Some vehicle manufacturers will trigger a voice E-112/E-911 call or a pre-help service call via all capable phones in the vehicle when a crash is sensed • Function provided on a best-effort basis only – no assumption of liability for call completion A separate, highly-reliable, crash-triggered service is also required to ensure that valuable data gets to a PSAP in the event of a crash 9 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 Automatic Crash Notification (ACN) o A crash-initiated “SOS” function for vehicles is different from and in addition to initiating a voice E-112/E-911 call o Requirements ... • A high-integrity operation that works for the service life of the vehicle • Very robust, embedded in-vehicle equipment • Since a regular mobile phone may not survive a crash • Messages are data-only, originated from the vehicle, and automatically triggered • Since vehicle occupants may be unable to talk or no longer in the vehicle after a crash ACN will provide this automotive-grade function 10 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 How ACN Meets These Requirements… o By sending a data message automatically from a vehicle when a crash is sensed (e.g. airbag deploys) • In addition to location, the data message can contain information about the crash and the vehicle’s occupants • Receipt of this information by the PSAP should reduce the arrival time of the right emergency services with the right equipment to deal with the precise crash situation o By being robust and crash tolerant o By working reliably for the service life of the vehicle, independent of other vehicle capabilities 11 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 E-112 with ACN Added Unless the driver directs otherwise, the ACN centre calls the PSAP that covers this vehicle’s location Data sent to an ACN centre LSP PSAPs emergency services LSP receives the message with the vehicle’s position, and routes it to the ACN call centre (or direct to PSAP, depending on level of capability) Assistance dispatched by the authorities to the location of the vehicle ACN centre wireline data voice wireless data 2 3 4 5 Additional data from the vehicle manufacturer (where available) Vehicle systems dial 112/911 from all mobile phones recognized in the vehicle, passing the vehicle’s position 1b In-vehicle device sends an ACN data message 1a wireless carrier 12 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 PSAP Perspective o Current considerations ... • Many PSAPs have will have challenges for years handling location with mobile E-112/E-911 calls • PSAPs are now having to find ways to locate calls made from internet voice over IP (VoIP) services • To ease the load on PSAPs, ACN messages can be • Automatically interpreted and displayed at an ACN centre supported by the vehicle manufacturers • Relayed by voice to the appropriate PSAP • For countries with advanced PSAP structures, the ACN data message can go directly to the PSAP o Information about the crash and the vehicle may also be made available to PSAPs on a secure internet site 13 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 Future ACN Approaches o Future ACN implementations could provide supplementary information on crash characteristics from onboard sensors o Additional data messages may be sent as more data about the crash is available o Some vehicle manufacturers may also send pre-crash data, to help evaluate • The type and severity of the crash • Performance of in-vehicle systems, especially as more complex, software-based safety systems appear in high-end vehicles o Privacy and data ownership and use rules, which are complex and vary by country, must be addressed 14 Session 4 ITU-T The Fully Networked Car, A Workshop on ICT in Vehicles ITU-T Geneva, 2-4 March 2005 Thank you for your attention horncastle@ygomi.com

ACN has changed materially and in non-compatible ways. (...) This problem should be addressed and not deflected. 12. ACN decoder readiness concerns “It should be noted that this is a design issue of the codec and not of ACN” “ACN can be slowed down on the decoder side, frames may be ignored or buffered until the decoder is available” Codec design issues should still be seen as part of the overall system solution. (...) If both terminals signaled support of ACN in a call, then the ACN procedure shall be used in that call.

When pimples get inflamed, this condition is called acne. Some of us have to deal with acne for many teenage years and there is no single treatment that works for all of us. (...) A lot of these products contain oils that can make your acne worse! • If you get acne on your body (e.g. back or thighs), avoid wearing tight clothes. (...) Doctors can recommend special creams or gels and medicines for your acne and can help you manage your acne better. • If you are taking prescription medication for acne, you must complete your medication as the doctor advised (unless the doctor tells you to stop it before that).
