Network Provided Location Information

Network provided location information (NPLI) is a service commonly supported within the IMS network architecture. NPLI is most commonly provided as a geographic identifier which specifies a location either in terms of geodetic coordinates (latitude and longitude), for example 42°25'33 N 71°18'16 W; or in terms of a recognized civic identifier, for example Lincoln, Massachusetts.

Support for NPLI was introduced in two phases. Initial, Phase 1 support for NPLI, was provided by Version S-CZ7.1.2. Enhanced, Phase 2 NPLI support, is provided by Version S-CZ7.2.0 and later releases.
