Section: 7.3.2 Requirements 7.3.2.1 General
Content: The 5G System shall provide different 5G positioning services with configurable performances working points (e.g. accuracy, positioning service availability, positioning service latency, energy consumption, update rate, TTFF) according to the needs of users, operators and third parties. The 5G system shall support the combination of 3GPP and non-3GPP positioning technologies to achieve performances of the 5G positioning services better than those achieved using only 3GPP positioning technologies. NOTE 1: For instance, the combination of 3GPP positioning technologies with non-3GPP positioning technologies such as GNSS (e.g. Beidou, Galileo, GLONASS, and GPS), Terrestrial Beacon Systems (TBS), sensors (e.g. barometer, IMU), WLAN/Bluetooth-based positioning, can support the improvement of accuracy, positioning service availability, reliability and/or confidence level, the reduction of positioning service latency, the increase of the update rate of the position-related data, increase the coverage (service area). NOTE 2: The combination can vary over time to optimise the performances, and can be the combination of multiple positioning technologies at the same epoch and/or the combination of multiple positioning technologies at different epochs. The corresponding positioning information shall be acquired in a timely fashion, be reliable, and be available (e.g. it is possible to determine the position). UEs shall be able to share positioning information between each other e.g. to a controller if the location information cannot be processed or used locally.
