911
« on: May 31, 2013, 03:35:49 PM »
In the USA E911 is an enhanced method of contacting the emergency services compared to the older 911 that people dialled. The caller is unaware of the difference.

The U.S. FCC (Federal Communications Commission) requires network operators to identify the phone number and cell phone tower used by callers, within six minutes and they are now introducing a precise location service E911

A firm that provides the hardware to the network operators to handle E911 calls (Enhanced 911) and has announced that its TCS VoLTE9-1-1 service is first into production with Tier-1 wireless carriers, including two of the largest North American operators (handling around half of all E911 calls).

What this means is that a 911 call enables the network operators to provide both 911 call routing and originating precise location information, including the callback number, to public safety access points (PSAPs), equivalent to the UK’. Precise location and callback are not available in the UK.

The company claim:
•Call routing to the PSAP: The TCS VoLTE9-1-1 service routes a 4G/LTE-originated 911 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 911 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, and picocells, which are now commonly used in dense urban, indoor areas and enterprise networks.

Impressive stuff as the USA leads the way in Emergency Call Handling.

Snippets on the net suggest we in Europe, under the umbrella of 112, will be getting a similar system. Anyone know anymore?

A student working with us watched your 112 video, as do all new staff, and she said that E112 was now available, is she right?”

Hi Callum, I have answered this question in the ‘Contacting the Emergency Services’ thread :)
