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 - registered name and address
  data kept up to date(end-user-gtCP1-gtCP2 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

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, CW, 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) - Dont rely on user-
  Dont rely on device (at least for next 2/3
  years)

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 ..

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)
