TeleCommunication Systems announced the availability of TCS VoLTE (Voice over LTE) 911, enabling carriers to reliably deliver emergency voice communication services as they transition to new 4G/LTE networks.

The TCS VoLTE 911 Solution includes:

  • Session Initiation Protocol (SIP) platform built for LTE and dedicated to 9-1-1 processing: The emergency call routing platform uses a robust, highly-reliable, standards-based SIP architecture that natively supports the IMS-based LTE network over which 9-1-1 calls are delivered.
  • Call routing to the Public Safety Answering Point (PSAP): The TCS 9-1-1 Emergency Call Server (ECS) Route Determination Function routes a VoLTE 9-1-1 call using well-established FCC Phase-I data (Cell ID) and further provides new routing capabilities based on Wi-Fi MAC Address and Femtocell ID.
  • Re-bid by PSAP for precise location after call routing: The TCS 9-1-1 ECS Location Retrieval Function (LRF) allows a wireless operator complete flexibility in choosing its underlying high-accuracy location technology. The ECS-LRF supports updated/precise position requests using any of the following:
  • Control Plan Location request using Mobile Location Protocol (MLP) to an E-GMLC (Evolved GMLC)
  • User Plane Location request using MLP to a User Plane Location Server
  • PSAP telecommunicators can call back if disconnected: The TCS solution remains fully backwards compatible supporting necessary functions such as providing PSAPs with full 10-digit subscriber callback numbers.
  • Emergency voice call continuity for location service: The TCS 9-1-1 ECS supports location continuity and location delivery to the PSAPs in the usage scenarios where the 9-1-1 call switches from 4G/LTE to 3G/2G networks.
  • Multiple provisioning interface tools: These tools make cell site database provisioning quick and easy and enables wireless operators to select the option that best meets their deployment needs, resulting in timely and responsive 9-1-1 data management.
