This Annex contains examples with mappings of SDP parameters to QoS parameters (
TS 23.107) for MTSI.
The bitrates used in these QoS examples for MBR and GBR for MBR=GBR bearers and for MBR for MBR > GBR bearers are based on the highest bitrates possible with the codecs, profiles and levels defined in
clause 5.2. The bitrates used for GBR for MBR > GBR bearers are chosen to still give usable quality levels.
The
'a=bw-info' attributed defined in
clause 19 can be used to provide additional bandwidth information for the setting of MBR and GBR and also to align the resource allocation end-to-end, see also
clauses 6.2.5 and
6.2.7.
The bearer setup also depends on the outcome of the SDP offer-answer negotiation. The QoS profiles shown below assume that both end-points agree on using the codecs and bitrates as described in each respective example.
The QoS Class Identifier (QCI) (
TS 23.203) and 5G QoS Indentifier (5QI) (
TS 23.501) are used to describe the packet forwarding treatment for different media types. The Table below gives a few examples for how the QCI/5QI can be set for different media types.
Media |
Bearer type |
QCI/5QI |
Speech | Dedicated GBR bearer | 1 |
Video (conversational) | Dedicated GBR bearer | 2 |
Video (non-conversational) | Dedicated GBR bearer | 4 |
Dedicated non-GBR bearer or default non-GBR bearer | 6, 8 or 9 |
Real-time text | Dedicated non-GBR bearer or default non-GBR bearer | 6, 8 or 9 |
Data channel | Dedicated GBR or non-GBR, or default non-GBR bearer | 71, 72, 73, 74, 76, or 9 |
This mapping assumes that the QCIs are used as described in
TS 23.203, Table 6.1.7 for LTE access, and 5QIs as described in
TS 23.501,
Table 5.7.4-1 for NR access.

Using a conversational class bearer means that resources are reserved throughout the session. Depending on the intended usage of real-time text, it might not be the most resource efficient choice to use a conversational class bearer, especially if it is foreseen that the sessions will be long-lived while the actual text conversations will be rare and bursty. Table E.4 therefore shows an example with QoS mapping for using an interactive class bearer. It is recommended to use QCI 6, 8, or 9 (
TS 23.203) for T.140 real-time text unless the service policy decides to assign different QCI types.
