Client requests single mobile terminal’s periodic location 2
Client requests multiple mobiles’ immediate location 2
Client requests single mobile terminal’s triggered location 3
Client request multiple mobiles’ periodic location 3

15.2.2 A Location Request Use Case
A subscriber wants to use a Location-Based Service. The Gateway Service is employed to obtain the position of the subscriber’s mobile terminal from the network. A Location
Service Client sends the request to determine a position to the Gateway. The Gateway calculates the position of the subscriber’s mobile terminal and forwards to the Location
Service Client, which may store it for as long as needed.
