  1. Emergency PositioningThe 1st European Security and Safety SummitJune 6 – 7, 2007 Ola Svensson Sales Manager Location Based Services Ericsson AB

  2. Market overview and demand for emergency positioning systems • USA • High accuracyA-GPS/U-TDOA • Combination ofpush & pull • Privacy protection EuropeanUnion • Japan • Initial push withlow accuracy • Consecutive pull using SUPL A-GPS

  3. “Operators should make caller location information available to authorities handling emergencies, to the extent technically feasible” Requirement in European Union

  4. But … • Different implementations due to national standards and national legislation • Funding by either the operators or by the government, variation from country to country

  5. High Accuracy Requirements? • There is no point in high accuracy in the operator networks if they Emergency Centers are not able to make use of the position • The core networks in Europe are not able to handle all call cases for emergency positioning

  6. The operator’s own subscribers Other national operator’s subscribers with roaming agreement (“own MVNOs”) International subscribers with roaming agreement Other national operator’s subscribers without roaming agreement (national camping) International subscribers without roaming agreement SIMless handsets What Calls should be Positioned? Can be handled by a standard positioning system Issue: From what network is the subscriber calling?

  7. The operator’s own subscribers Other national operator’s subscribers with roaming agreement (“own MVNOs”) International subscribers with roaming agreement Other national operator’s subscribers without roaming agreement (national camping) International subscribers without roaming agreement SIMless handsets Modifications of Network infrastructure needed Issues: From what network is the subscriber calling? Where in the network? How to identify the subscriber/handset? “Tough” Call Cases

  8. Pull Commercial positioning systems can be used to handle “easy” call cases Some delay of the delivery of the position Can support both low and high accuracy Also “tough” call cases can be handled with additional network support Privacy concerns Push “Easy” implementation of support for positioning of all call cases with low accuracy Instant delivery of position High accuracy can be handled with additional network support No need to bother about from which network or where in the network the call is made Inherent support for privacy What method should be used?

  20. Privacy ConcernsCall Related Positioning • Mechanism in the MSC to secure that the positioning of the calling party can only be performed by the called party (B-number included in positioning request) • Privacy Override contradiction

  21. Other E112 Requirements • Multiple distributed positioning databases • Multiple emergency numbers in addition to 112 (e.g. 999) • Full geographical resilience

  22. Current Deployments • Ericsson has implemented support in MSC for all mechanisms outlined in this presentation • The updated core network support is deployed at two operators in Switzerland • All other Ericsson core networks in Europe needs upgrading to support the full functionality • Other core network vendors?

  24. Conclusions • Full support for E112 can only be achieved by adding new functionality to the network infrastructure • E112 can be implemented in many different ways, a combination of push and pull offers both a fast response and a path to high accuracy • High accuracy will be introduced in the networks driven by consumer demands
