Evaluation of path-loss technologies for Location Services (LCS)
<Editor's note: Text in this section is cited from the original text in 'Annex A.1 Overview'>
Path-loss technologies cover a broad scope of specific location technologies, including: RSSI Trilateration technologies, certain Enhanced Cell-ID technologies, and RF pattern matching technologies. For the purposes of this Study Item, individual technology groups to be evaluated will be treated independently as Annexes to the TR.
In this TR, Annex.A should:
- Describe pattern matching and outline it's benefits and challenges.
- Illustrate the required messaging to support RF pattern matching technologies, as well as the projected performance improvements associated with additional messaging/measurement support.
- Confirm the performance capability of RF pattern matching Technology on the UMTS air-interface, over all environments. Both in terms of accuracy and location result latency:
- Dense Urban
- In-Building
- Rural
- Illustrate the Standardized architecture for RF pattern matching technologies as related to the UMTS and future air interfaces.
- Provide an outline of anticipated standardization requirements for improved performance and interoperability of RF pattern matching technologies.
- Provide a conclusion based on the information contained herein and a recommendation to the 3GPP regarding standardization of RF pattern matching Technologies within the RAN.
