• Issue: Cyclic reference in location-verification

  • Commented. It should not be a problem the current specification.

    • We keep it open for now

• Issue: Semantics of the absence of 'maxAge'

  • Discuss in meeting

    • Not sure why this 60 seconds limit.

    • Apply for Retrieval & Verification

    • We can change: 

      • Alternative (1) will be to change this limit value from 60 to x

        • if x=0: We have to specify that 0 means 'very recent' location (expectation from request is get the device location right now). If not able 'unknown' should be sent.

        • if x=5 (or other >0): We keep semantic of maxAge unchanged

      • Alternative (2) will to state that if maxAge not value it means real time location is requested.

      • Alternative (3) is to add additional parameter to explicitly ask for current location.

    • Preference from the team to alternative (1) but we keep the discussion open.

    • if maxAge is not valued then we expect to retrieve the latest location (that could be 2 hours ago).

    • Javier also opened the discussion about improving the accuracy limit (2000 meters as of now).

Long term discussions

Administrative Code Area

• New Issue #83, with formal requirements from GSMA Product track

  • Document uploaded by TEF with a proposal.

  • Review priority and next steps → Clarify this:

    • More generally probably we need to have feedback loop with GSMA team about API work (and review the priority as focus could change)

      • Done during last TSC - see here: https://lf-camaraproject.atlassian.net/wiki/display/CAM/2024-03-21+TSC+Minutes

Implementation

• Define guidelines for geofencing implementation

  • We need more comments from the team

  • Connected with Issue #85. A document with implementation guideline should cover this also.

   

• Issue #85

  • As requested by Joachim, issue will remain open until TEF uploads the document with more detail or the information is added to an API_documentation file to keep in the repo for future references.

    • Joachim: Should be also aligned/synchronized with Geofencing
