4. 21-08-0085-00-0000 Abstract The purpose of this presentation is to determine interest in the formation of an IEEE 802.21 Study Group about Emergency Service (ES) provision

5. 21-08-0085-00-0000 IEEE 802 ES Background Maturing IEEE 802 technologies carry VoIP traffic and it’s only a matter of time before regulations insist they support emergency services. (FCC & EU commission proposals) IEEE 802 technologies by themselves cannot ensure that all factors are compatible for Emergency Service sessions to actually take place. Therefore, it’s essential to distinguish between the minimum level of support provided by IEEE 802 emergency services, and support of emergency services at higher layers. By “IEEE 802 Emergency Services” we refer to the direct support in IEEE 802 technologies of such services, independently of what solutions are adopted at higher protocol layers. Under all circumstances, changes to IEEE 802 technologies should be kept to the minimum necessary.

6. 21-08-0085-00-0000 Do What? To initiate a Study Group WGSG: Technology specific, 802.1, 802.15 etc ECSG: Harmonized approach to ES in all 802 groups This study will take into account regulatory issues and the architecture requirements of NENA i2 & i3, IETF ECRIT and 3GPP/3GPP2 architecture requirements on radio access technologies. Attempt to pre-empt upcoming regulatory issues Determine what aspects of ES would benefit from a harmonized approach across all IEEE 802 technologies.

7. 21-08-0085-00-0000 Relevant Requirements Ability to support ES calls (various media types) Support for callback Unauthenticated calls (no credentials in terminal) Roaming and non roaming Emergency Alert System (EAS) service Authority – authority communications Citizen – citizen communications Location (Automatic Location Identifier) Common Approach Note: This is not a location provisioning group

8. 21-08-0085-00-0000 ES Interest Initial interest in ES within 802.11 Other interest from 802.1 LLDP-MED is a adopted wired solution with location support. Subsequent interest from 802.21 (802 handover) Provision of ES Information Server Some interest from 802.15 (15.4) and 802.16 ZigBee and 802.16d (fixed) community Additional Information IEEE 802 Tutorials at March and July 2007 plenary meetings. Attendance ~150 Liaisons between IEEE 802.11, NENA and IETF ECRIT

9. 21-08-0085-00-0000 Study Group Future work Study group will consider existing work in this area industry input network and service provider input what do regulators require Scope Media Independent Emergency Services (restrict scope to IEEE 802 technologies) Defined Goals and Timeframe To determine what work, if any, is necessary to enable an harmonized approach to emergency service provision across IEEE 802 technologies.

10. 21-08-0085-00-0000 Background/Relevant Aspects IEEE 802.1 LLDP-MED currently supports automatic physical location discovery suitable for wired 802 networks 802.1AB-Rev work in process could allow location discovery to be leveraged across all 802 technologies

11. 21-08-0085-00-0000 IEEE 802.11p Supports Intelligent Transportation Systems (ITS) applications. This includes data exchange between high-speed vehicles and between the vehicles and the roadside infrastructure in the licensed ITS band of 5.9 GHz. ES from vehicles to authority (eCALL blackbox) Authority – authority vehicle comms

12. 21-08-0085-00-0000 IEEE 802.11u New QoS features expedited bandwidth request QoS mapping Generic Advertising Service (GAS) Emergency services recommendations (informative) Use case #1: open network Use case #2: public credentials

13. 21-08-0085-00-0000 IEEE 802.11v Reliable Location Determination Capability information includes Format (Civic, Geo – shapes not points, Location by Reference…etc) Encoding and Resolution Capable of providing self-location remote-location

14. 21-08-0085-00-0000 IEEE 802.21 Information Server logical place to support a comprehensive list of all ES support options. Mobility support assisting handovers during an ES session Location Service providers need flexibility on how location services are offered in their network Provides help in determining or provide the location to the clients at various layers Link layer specific ones (Layer 2) Link layer agnostic ones (Layer 3+)

15. 21-08-0085-00-0000 Other Requirements? 802.16/20/22 Location Determination NG911 Support for non-voice ES connections (e.g. text messaging, email, video)

16. 21-08-0085-00-0000 Summary Study group Scope Media Independent Emergency Services restricted to IEEE 802 technologies Purpose To determine what work, if any, is necessary to enable a harmonized approach to emergency service provision across 802 technologies Timeframe 2 plenary cycles, to investigate PAR definition
