ITU-T Q.3932.4 PDF

This Recommendation contains the benchmark testing of signalling parameters against the performance design objectives specified in ITU-T Q.543 and ETSI TS 101 563, which are applicable to IMS/PES/NGN and VoLTE implementations. The values of the performance design objectives (reference load A and reference load B), which are contained in this Recommendation and found in Table 1 to Table 9, are taken from ETSI TS 101 563. These values are "best practice" performance values measured on IMS/PES/NGN and VoLTE implementations.
