E QoS profiles p. 329

E.1 General p. 329

This Annex contains examples with mappings of SDP parameters to QoS parameters [64] 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) [90] and 5G QoS Indentifier (5QI) [176] 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.

Table E.0: Example mapping between media type and QCI.

Media	Bearer type	QCI/5QI
Speech	Dedicated GBR bearer	1
Video (conversational)	Dedicated GBR bearer	2
Video (non-conversational)	Dedicated GBR bearer	4
Video (non-conversational)	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 [90] for T.140 real-time text unless the service policy decides to assign different QCI types.

Residual BER	10^-5	Reflects the desire to have a medium level of protection to achieve an acceptable compromise between packet loss rate and speech transport delay and delay variation.
SDU error ratio	7*10^-3	A packet loss rate of 0.7 % per wireless link is in general sufficient for speech services
Transfer delay (ms)	130 ms	Indicates maximum delay for 95th percentile of the distribution of delay for all delivered SDUs between the UE and the PS domain during the lifetime of a bearer service. Permits the derivation of the RAN part of the total transfer delay for the radio access bearer. This attribute allows RAN to set transport formats and H-ARQ/ARQ parameters such as the discard timer.
Guaranteed bitrate for uplink (kbps)	33	The total bit-rate of AMR5.9 including IP/UDP/RTP overhead and 5 % for RTCP.
Maximum bitrate for uplink (kbps)	39	The total bit-rate of AMR12.2 including IP/UDP/RTP overhead and 5 % for RTCP.
Guaranteed bitrate for downlink (kbps)	33	The total bit-rate of AMR5.9 including IP/UDP/RTP overhead and 5 % for RTCP.
Maximum bitrate for downlink (kbps)	39	The total bit-rate of AMR12.2 including IP/UDP/RTP overhead and 5 % for RTCP.
Allocation/Retention priority	subscribed value	Indicates the relative importance to other radio access bearers. It should be the next lower value to the priority of the signalling bearer.
