Executive summary
The Pan-European Mobile Emergency Application (PEMEA) architecture provides a framework to enable applications
supporting emergency calling functionality to contact emergency services while roaming. PEMEA caters for a range of
communications extension capabilities, including services for people with disabilities. Service continuity is important,
and of particular concern during technology rollouts prior to service ubiquity being achieved. The present document
describes the PEMEA Service Discovery capability, enabling App users to determine in advance of placing a PEMEA
communication request whether PEMEA or a particular communication technology is available to service the caller's
needs in a certain area. This allows the App users to make an informed choice on how best to reach emergency services.

Introduction
PEMEA was originally designed to allow mobile emergency applications to roam across Europe. Deployment of
PEMEA is not yet ubiquitous and not all regions where it is deployed offer all of the available PEMEA services.
ETSI TS 103 478 [1] does not define a mechanism to determine if the region that a caller is in supports PEMEA or what
services of PEMEA it does support. The present document describes an extension capability for PEMEA for
determining if PEMEA is supported in a region and what capabilities the PEMEA deployment provides.
The present document assumes a working knowledge of PEMEA and familiarity with the PEMEA specification ETSI
TS 103 478 [1].
