"The present document addresses generic architectures for GNSS-based Location Systems (GBLSs) that combine Global Navigation Satellite Systems (GNSS - e.g. Galileo?) and other navigation technologies with telecommunication networks for delivery of location-based services. The architecture specified herein is a ""functional"" architecture@ meaning that the system is defined in terms of discrete functional elements connected to other internal or external functional elements via associated ""logical"" interfaces. These functional elements and interfaces are derived from service requirements. The functional architecture is not necessarily related to the ""physical architecture"" (i.e. the relationship between equipment which may implement all or some of these functions@ and the physical interfaces between them). The present document can be considered as the Stage 2 functional specification according to the ITU/3GPP approach [i.4]."
