The invention relates to a method for using a service enabler architecture layer for verticals, SEAL, in a vertical
application layer implementation, VAL implementation, for providing communication services to a
user equipment, using a vertical
application layer server via a
telecommunications network, especially for supporting and providing a location check functionality and / or verifying location-related data indicative of the actual location or position of the
user equipment, wherein the
user equipment is a vertical
application layer user equipment comprising a vertical application layer
client, VAL
client, and an location management
client, wherein the service enabler architecture layer for verticals comprises a location management
server that is able to realize a location check functionality and / or verifying location-related data indicative of the actual location or position of the user equipment, wherein, in order for supporting and for providing, by the location management
server, a location check functionality by means of confirming
location data and / or verifying location-related data indicative of the actual location or position of the user equipment towards a confirm
location data consumer entity, the method comprises the following steps: -- in a first step, the location management client transmits a confirm location request to the location management server in order for the location management server to perform a location check functionality and / or verifying location-related data indicative of the actual location or position of the user equipment, -- in a second step, the location management client receives, from the location management server, a confirm location response, wherein the confirm location response comprises a confirm
location status information, and the confirm
location data consumer entity receives, likewise from the location management server, a confirm location
service usage notification.
