PEMEA means Pan-European Mobile Emergency Application and it’s an architecture that solves the problem of localized emergency applications that provide high-accuracy user location information to local emergency services when an emergency call is made not working when the user is outside the area that the application was intended to work in.
That is, PEMEA allows mobile applications to provide accurate location and user information to the correct emergency answering point irrespective of where the user has roamed to. Any application that make an emergency call can use PEMEA to ensure the user is found quickly.
This standard give the emergency services a tecnological modernization, expanding the coverage this centers can give to the citizen by implementing new necesary features to give the service they need. Furthermore, this features asure the coverage to some groups not covered before.
App: Application that resides on the device, smartphone, tablet or laptop.
PSAP: Emergency answering point. The PSAP is able to use the information from the PEMEA message and associate with the emergency call. This provides the PSAP operator with accurate location information for the caller, as well as other information about the caller, including their name, what languages they speak and people to contact if the caller is in a bad way. The PSAP is able to use the information from the PEMEA message and associate with the emergency call.
Application Provider(AP): The role of the AP is to take the proprietary interface and data formats between the application and convert them to PEMEA messages. The AP may provide user information to any PEMEA-enabled PSAP or terminating-PSP with the PEMEA network, this information is controlled by the receiving PSAP and terminating-PSP processes and policies, and these should align with GDPR guidelines.
The PSAP service provider (PSP): is the gatekeeper between the PSAP and the PEMEA network. It has direct relationships with Application Providers that it trusts, other PSPs that it trusts and with special trusted routing nodes called aggregating service providers (ASPs) that can route PEMEA messages to PSPs in other regions and countries that the first PSP may not know about. The PSP is the first routing node in the PEMEA network, it looks at the location of the caller and determines if the information is a local PSAP or not, if it is not then it will pass it on to either another PSP or to an ASP depending on configuration.
The aggregating service provider (ASP): can be thought of as the “PEMEA street directory”, it knows about other ASP and PSPs and what regions they server, and is responsible for sending PEMEA data messages to these nodes so that the user data ends up at the same PSAP that the call does.
