  1. Emergency Services Workshop UK VoIP 999/112s John Medland – BT 999/112 Policy Manager

  2. UK Emergency Service today (222 Local Controls) Police 56% BT or CW Operator Centres Ambulance 35% BT or CW Public Ntwk (PSTN) PSTN Fire 8% 999/112/ 18000 Other Networks Coastguard<1% BT – 28m calls, 50% mobile, every call voice + location 999/112/18000

  3. Handling VoIP 999/112 now • Reach Call Centres through PSTN/IP Gateways • Identified as VoIP • Registered address accessed through tel number • Name and address marked as needing confirmation • Verbal routing………. • Devices/CPE use PSTN/GSM for 999 if possible • Key issues for VoIP 112/999 : - provision of 112/999 access - registeredname and address data kept up to date(end-user->CP1->CP2 to PSTN and PSAP) • - 24 hour VSP contact point for PSAP use (tracing, alternative contacts)- lack of information to PSAP for nomadic users (definition of nomadic)- end user education- how to Automate Location provision………

  4. NICC Task Group • The Network Interoperabilty Consultative Committee : NICC is a UK telecommunications industry committee which acts as an industry consensus group in which specifications and technical issues associated with network competition can be discussed. It also is a source of advice to the Director General of Telecommunications on the harmonisation of interconnection arrangements • Location Task Group : Routing 999/112 for VoIP to correct local EA with VoIP caller location information • Membership : ITSPA, ISPA, BT, C&W, Ericssons, Huawei, Andrew, ETSI, Gradwell, Magrathea, Thus, Truphone, IN UK, Virgin Media and Ofcom +…. • Approach :-- VSP, ISP and Access Provider(s) all different - Start with DSL and than tackle Cable, WiFI and GSM scenarios - Standards still developing (use wherever possible, eg IETF, ETSI) - Start with UK only (but need to allow for International dimension) - Don’t rely on user- Don’t rely on device (at least for next 2/3 years)

  5.

  7. Implications Yes, automated routing and location provision is technically feasible (for ADSL case) but will imply :- • New requirements on all organisations (systems development) • Many more organisations involved to deliver 112 (not just traditional telcos but VSPs and ISPs) • New operational components : LIS and VPC • New interfaces for all organisations: based on international standards as far as possible (eg IETF HELD) • Increased co-op between PSAP and VSP, ISP and Access networks • Detailed document is now going through NICC review process …………………..

  8. Challenges to adoption • ISPs storing and updating association of IP/Line ID/ location at an ISP LIS • LIS cascades to access providers and length of response times • ANPs storing and updating association of (IP)Line IDs/ location at ANP LIS • Challenging business cases (!) unless regulatory driven • Current regulatory responsibility unclear when several CPs and an ISP involved

  9. Further Challenges • National solutions are being developed • National solutions will need to evolve to cover international IP roamers • Long transition periods with hybrid TDM/IP services • Multimedia calls : all organisations need clear 112 requirements driven by users (112Net?)

  10. Next Steps • Next Steps :-- Finalise basic architecture and BB ADSL scenario detail - Continued work on other UK scenarios (Cable, LLU, Private networks)- International Scenarios - IP end-to-end (as NGN, PSAP +device capabilities become clear)
