E.31  Bi-directional speech (EVS 13.2, IPv4, RTCP and MBR=GBR bearer) |R13|p. 359

The bit-rate for EVS 13.2 including IP overhead (one EVS frame per RTP packet, using Header-Full format) is 30 kbps. IPv4 is assumed.
Traffic class Conversational class Notes
Delivery orderNoThe application should handle packet reordering.
Maximum SDU size (octets)1400Maximum size of IP packets.
Delivery of erroneous SDUsNo
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 msIndicates 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 bit-rate for uplink (kbps)32The total bit-rate of EVS 13.2 including IP/UDP/RTP overhead and 2000 bps for RTCP.
Maximum bit-rate for uplink (kbps)32The same as the guaranteed bit-rate.
Guaranteed bit-rate for downlink (kbps)32The total bit-rate of EVS 13.2 including IP/UDP/RTP overhead and 2000 bps for RTCP.
Maximum bit-rate for downlink (kbps)32The same as the guaranteed bit-rate.
Allocation/Retention prioritysubscribed valueIndicates the relative importance to other radio access bearers. It should be the next lower value to the priority of the signalling bearer.
