TeleCommunication Systems extends NG-911 support to VoLTE networks
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.
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.
