Ny understanding is that typically there would be a location service that queries this information from oFono and converts it into actual coordinates through voodoo and black magic and that location-aware applications will ask this location service for coordinates. E.g. you would have something like GeoClue providing a single API for providing coordinates to applications and under GeoClue there is the location service, and the location service in turn talks to oFono.
