TCS Voice over LTE 9-1-1 (VoLTE9-1-1)

Built upon the single largest VOIP emergency call processing platform in the nation, the TCS VoLTE9-1-1 (Voice over LTE) solution is cost-effective, highly flexible, and standards-based. This service is fully customizable according to the carrier’s LTE infrastructure.

VoLTE9-1-1 Architecture

Features

• Call routing to the Public Safety Answering Point (PSAP) serving the caller’s location:
  • The TCS 9-1-1 Emergency Call Server (ECS) Route Determination Function (RDF) routes a VoLTE9-1-1 call based on coarse location using Cell ID, Wi-Fi MAC Address or Femto ID.
• Re-bid by PSAP for precise location after call routing:
  • The TCS 9-1-1 ECS Location Retrieval Function (LRF) can respond to a rebid for an updated/precise position using an Evolved GMLC (Control Plane) or a Secure User Plane Location (SUPL) Server.
• PSAPs can respond to dropped calls:
  • PSAPs are provided with a 10-digit subscriber callback number.
• Emergency voice call continuity for location service: 
  • The TCS VoLTE9-1-1 solution supports location continuity to the PSAPs in the case of handovers from 4G/LTE to 3G/2G networks.
• Multiple provisioning interface tools – CDM tool, LIS API, B2B API, RF email submissions):
  • These make cellsite database provisioning quick and easy.
