1. APCOA Conference – Feb 2011 Enhanced Mobile TripleZero Delivering Accurate Location for Mobile Emergency Calls Martin Dawson CommScope/Andrew Australia martin.dawson@andrew.com

2. 2 © 2010 CommScope, Inc Introduction On January 27 the ACMA published an amendment to the Telecommunications (Emergency Call Services) Determination of 2009 –http://www.comlaw.gov.au/Details/F2011L00157 –It introduced minimum standards for mobile carriers in relation to the provision of mobile location information to emergency service organisations (ESOs) – police, fire or ambulance. What sort of location information can mobile networks provide, how is it done, how can it help?

3. 3 © 2010 CommScope, Inc The standard emergency service Mobile Switch 2G & 3G Radio Network Call Centre ESO Telephone Network GMLC SMLC Call Location Measurements Mobile Network standards define exactly how emergency calls are recognized and delivered. Location is available for all calls Regular subscribers Inbound/foreign roamers SIMless and unregistered Calls completely handled by serving network No dependency on home/foreign networks All Australian networks support these standards Mobile switch routes call through telephone network (as normal) Switch always triggers location request to SMLC* at start of call SMLC takes measurements from network and, optionally, from handset (e.g. GPS) Location is available at GMLC* for request by Call Centre Call Centre can ask for accurate location updates at any time during call * SMLC – Serving Mobile Location Centre GMLC – Gateway Mobile Location Centre

4. 4 © 2010 CommScope, Inc There are numerous options for location determination RF Profiling Cell and Rx level info RF survey DB Note: Modern standards support E-CID as the most basic/cheapest method available. E-CID results are available effectively as quickly as basic Cell-ID location.

5. 5 © 2010 CommScope, Inc Rockville Hard Place A car leaves the road and disappears into bush Driver calls 000. They are barely conscious They are losing blood All they can really say is that they were driving to Hard Place Caller is visiting from the UK and using their foreign mobile Should responders be despatched from Rockville or Hard Place? Where is the accident?! Use case: Between Rockville and Hard Place

6. 6 © 2010 CommScope, Inc Rockville Hard Place Cell Tower Cell-ID – Confirms coarse location 25km search range Cell-ID confirms the situation but does not resolve the dispatch dilemma. Responders will need to search the length of the road for the crash site

7. 7 © 2010 CommScope, Inc Rockville Hard Place Cell Tower E-CID – High value improvement Enhanced Cell-ID uses already available network measurements to give 50-500m range precision for 2G/3G. Resolves dispatch dilemma and minimizes crash site resolution time. 50-500m range

8. 8 © 2010 CommScope, Inc Rockville Hard Place A-GPS – The precision of satellite fixes If phone has GPS, the network can automatically turn it on for emergency fixes. Network assists GPS with satellite data and additional network measurements (i.e. A-GPS). A-GPS fix

9. 9 © 2010 CommScope, Inc Location Technology – Selectively Applied 2G 3G Modern networks support E-CID everywhere as the most basic and economical location determination method. E-CID accuracy location is automatically made available for every call. Higher accuracy location methods are invoked at request of the ESO during the call. Higher accuracy technologies can be regionally based – e.g. LMUs, RF Profiling Or opportunistic – e.g. A-GPS Modern networks support E-CID everywhere as the most basic and economical location determination method. E-CID accuracy location is automatically made available for every call. Higher accuracy location methods are invoked at request of the ESO during the call. Higher accuracy technologies can be regionally based – e.g. LMUs, RF Profiling Or opportunistic – e.g. A-GPS Emergency Call Centre

10. 10 © 2010 CommScope, Inc Not just for Triple-Zero Mobile Switch 2G & 3G Radio Network Triple-Zero Telephone Network GMLC SMLC Measurements The same location technology is available for all applications if standards are followed. Locate devices whether they are on calls or not Network can even tell what kind of application it is and apply priority and other policies Emergency Lawful Intercept Commercial value-added services * SMLC – Serving Mobile Location Centre GMLC – Gateway Mobile Location Centre Emergency Warnings Lawful Intercept Commercial Services Voice/TTY Location

11. 11 © 2010 CommScope, Inc So – it’s all good? Warning – it is easy to get wrong E.g. much of Europe is stuck with Cell-ID and inability to locate roamers because standards were not adopted –Europe now looking at time consuming effort to re-implement –To be fair – they implemented ten years ago and wouldn’t do it that way now On the other hand Canada launched nationwide standards-based system in 2010 and in less than 12 months from regulation Standards exist for network elements and procedures. Standards exist for call centre communication and interaction. –Not implementing to standards can result in less effective systems that cost more to implement and operate ACMA Emergency Call Service amendment (Sect 52A) states: If an emergency service organisation asks a mobile carrier to provide location… the mobile carrier must give … the most precise mobile location information available…as soon as possible However, “most precise… available” and “soon as possible” are not defined –It would be possible, for example to implement emergency location such that only Cell-ID is available, and only for non-roamers, even as commercial services etc can access higher accuracy information! Network Determined Location – The first link in the dispatch chain Let’s get it right Australia!!
