Call routing to the PSAP: The TCS VoLTE9-1-1 service routes a 4G/LTE-originated 9-1-1 call using coarse location via the route determination function component.

PSAP telecommunicators can call back if disconnected: The TCS VoLTE9-1-1 service remains fully backwards compatible, supporting necessary functions such as providing PSAPs with full 10-digit subscriber callback numbers.

Re-bid by a PSAP for precise location after call routing: The location retrieval function allows a wireless carrier complete flexibility in choosing its underlying high-accuracy location technology and supports updated/precise position requests.

Emergency voice call continuity for location service: Location continuity and location delivery to the PSAPs are supported in usage scenarios where the 9-1-1 call switches from 4G/LTE to 3G/2G networks.

Expansion beyond voice: As wireless networks advance, multimedia objects such as text, audio and video can be transferred to a compatible termination point with LTE IP networks; for example, an NG ESINet and i3 PSAP. Leveraging an all-IP network makes it easier and more cost effective to interconnect services.

Small cell support: The TCS VoLTE9-1-1 solution supports small cells, including femtocells, microcells, picocells, etc., which are now commonly used in dense urban, indoor areas and enterprise networks.

TCS VoLTE 9-1-1 is designed and supported by the company’s experienced location-based services and deployment team, who are active participants and contributors to LTE standards for 9-1-1.TeleCommunication Systems, Inc.
