Design Requirements and Goals for
Location Infrastructure
Partner Components Connexon Intrado i2 architecture RFC 4119
Location Determination Customer Site Switch: 10.0.0.1 Port: 6/29 425-706-1442 0016E3A558CA 172.24.33.132 Chicago 911 Router MSAG Pool with LIS Seattle E911 Service Provider 1. Map of network elements and locations created in Location Information Server (LIS) 2. lis addresses validated with Master Street Address Guide 3. Premises connected client acquires LIS URI, emergency dial strings, and configuration setting, and sends Location Request with IP / MAC / BSSID address to LIS upon registrations or network change 4. lis returns civic address to client based on network address lookup in database
Call Routing Customer Site Switch: 10.0.0.1 Port: 6/29 425-706-1442 0016E3A558CA 172.24.33.132 Chicago 911 Router MSAG Pool with LIS Seattle E911 Service Provider 1. Client initiates 911 call and includes location and E.164 number in SIP Invite 2. CS 14 matches 911 number pattern and routes to SIP trunk connecting to E-911 Service Provider 3. E-911 Router references civic address to route call to correct PSAP 4. Service provider optionally conferences in on-premises security to call 5. PSAP able to call back using E.164 number
