exploring new ways to contact the emergency services via,
for example, social media, texting or sending video clips.

Our Network Technologies committee (TC NTECH) will

interfaces of the functional architecture for emergency caller
location determination and transport, in support of European
Commission (EC) Mandate M/493. This service is intended
to cover a situation where different service providers and
network operators need to co-operate to determine the
location of an emergency caller.
We will continue to develop conformance testing for eCall,
the in-vehicle emergency call service which automatically
relays data about an accident from the vehicle involved to
the emergency services.

Other Public Safety Activities
In the Third Generation Partnership Project (3GPP™) we
are helping to develop the use of LTE for mission-critical
communications. In 2017 3GPP will complete standards for
the extension of mission-critical services from simple voice
to data and video in Release 15, making LTE technology
attractive to an ever-widening user community.
