Introduction

“It seems that the Federal Communications Commission (FCC)’s ultimatum to VoIP providers issued this May about having E911 access ready for Q3 05 has served its purpose. More VoIP technology providers have lined up to announce their VoIP E911 access readiness”

New elements in ‘NENA i2’

Emergency Services Gateway (ESGW) ESGW provides interconnection point between the VoIP domain and

existing Emergency Services Provider Network The ESGW provides protocol interworking between Session Initiated

Protocol (SIP) and call setup signaling to the E9-1-1 tandem (Multi-Frequency [MF] or Signaling System #7 [SS7])

VoIP Positioning Center (VPC) Receives and stores information about an emergency call, including

callback number information and location information May query LIS with LocationKey (LK) to obtain Location Object (LO) Based on LO, VPC determines Emergency Services Routing Number (ESRN),

and allocates an Emergency Services Query Key (ESQK) associated with the VPC, the call instance and the Emergency Service Zone (ESZ) from which the call originated. Also Contingency Routing Number (CRN) for alternate routing

Responds to subsequent queries for location information for that call instance from the PSAP via its serving ALI database, using the allocated ESQK

Emergency Service Query Key (ESQK) Emergency Service Query Key (ESQK) – The ESQK identifies a call

instance at a VPC, and is associated with a particular SR and PSAP combination. The ESQK is delivered to the E9-1-1 SR and as the calling number/ANI for the call to the PSAP. The ESQK is used by the SR as the key to the Selective Routing data associated with the call. The ESQK is delivered by the SR to the PSAP as the calling number/ANI for the call, and is subsequently used by the PSAP to request ALI information for the call. The ALI database includes the ESQK in location requests sent to the VPC. The ESQK is used by the VPC as a key to look up the location object and other call information associated with an emergency call instance. The ESQK is expected to be a ten-digit North American Numbering Plan Number.

The different organizational entitiesand resulting complexity


Open question on ‘NENA i2’

Regarding the ‘VoIP domain’

Which elements are hosted on the enterprise side ?

Which elements are hosted on the public side ?

VoIP E911 / Patrick DANIEL / 6-Oct-05


Recommendations based onNENA i2 market solutions analysis

ESGW & VPC functions outside IP PBX perimeter

Push ‘Indoor LIS’ integration. Consequently, openness to next Location-based Services

Push ‘Indoor VPC proxy’ integration combined to signed contract with VPC operator for ‘dynamic location updates’ capability• Denied access issue to enterprise network is then

resolved• Only SIP exchanges simplifying IP PBX architecture

evolutions Challenge these recommendations

Level 3 & TCS agreement / Sept 05

To provide this service to Level 3's customers, TCS delivers the following key functions: Location Determination -- validated subscriber location

database featuring a hosted real-time provisioning interface; Route Determination -- real-time call flow integration where

the VoIP Positioning Center (VPC) receives the 9-1-1 call and determines the appropriate PSAP to which the call should be routed using Emergency Routing Database and PSAP routing reference data;

Call Delivery -- routing instructions are returned from the TCS VPC to the serving softswitch to route across the Level 3 network to the PSAP via selective routers;

Location Content Delivery -- in response to an Automatic Location Information (ALI) query from the PSAP, TCS' ALI Link(TM) provides the caller's location data;


TCS issued patent Sept 15, 2005

http://www.marketwire.com/mw/release_html_b1?release_id=95300 The patent provides a means for querying a Message Servicing Center (MSC) from a VoIP switch and a means for receiving an Emergency Services Routing Key (ESRK) in response. Additionally, the patent allows querying by an Automatic Location Identification (ALI) database for caller information related to the ESRK
