Rapporteur:  Mr. Kåll, Jan
See also:  LCS-related TS/TR

This TR for Rel-5 identifies and describes enhanced user privacy in location services (LCS) and the corresponding functional requirements. The TR describes some possible enhancements to the privacy mechanisms provided for Location Services to support the increasing number of LCS clients and the varying privacy requirements for location services. The TR describes the stage-2 type of functional requirements for enhancing user privacy in location services that may be moved to the LCS Stage 2 specification TS 23.271, as seen feasible by TSG SA2.

The basic network solution as standardized in TS 23.271 Release 5 is described in general terms in the TR, with an indication of what enhanced privacy features are supported in Rel-5. The further enhanced LCS privacy features in Rel-6 and some alternative network solutions to support user privacy in Release 6 are also described and compared.

It should be noted that the GMLC-GMLC interface (Rel-6) is not taken into account in most network alternatives described in this report.
