scope:

This Technical Report addresses the incompatibilities that exist in the way that the 3GPP and the ITU have addressed QoS classes for IP-based packet flows.

This Technical Report has several purposes. It formally documents important work done earlier in the former Committee T1's T1A1 Subcommittee, specifically the mapping of QoS classes between the ITU-T's Y.1541/Y.1221 and the 3GPP's TS 23-107 (for UMTS). (This work was captured in various T1A1 contributions, and in external liaisons to the ITU and the 3GPP, but it was never documented in an ATIS publication, so it is done so here.)

With the formal documentation of the QoS class mapping between the ITU and UMTS presented, the next purpose of this document is to examine the same question of QoS class mapping between the ITU and LTE classes. It is shown that, as was the case for UMTS, a rigorous mapping that fulfills the numerical performance objectives of both domains is neither meaningful nor possible.

As the ultimate goal in the industry is fixed/mobile network convergence, some form of interworking will be necessary, and it is the purpose of this document to establish the foundation for quantitative methods capable of supporting this critically needed interworking.
