Abstract
Delays in accessing the service (delays in user/terminal authentication or call set up) and/or denial of service due to non-availability of resources (call blocking, hand-off failure) are key traffic performance parameters for PCS (personal communication service). These parameters will have a significant impact on the quality of service perceived by the end users of PCS. Suitable standards (target limits) for such traffic parameters are required to ensure user-acceptance of emerging PCS services. This paper summarizes the approach adopted by the ITU-T (ITU Telecommunication Standardization Sector, formerly CCITT) on developing traffic performance standards for Personal Communication Services. In ITU-T these services are being addressed as part of UPT (Universal Personal Telecommunication) and FPLMTS (Future Public Land Mobile Telecommunication Systems) standards. The former addresses the personal mobility aspects of PCS (for wireline and wireless access) and the latter addresses the terminal mobility aspects (wireless access).>

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
