Section: 8.16 Flow Quality of Service (Flow QoS)
Content: Flow Quality of Service (Flow QoS) is transferred via GTP tunnels. The sending entity copies the value part of the Flow QoS into the Value field of the Flow QoS IE. Figure 8.16-1: Flow Quality of Service (Flow QoS) Octet 5 contains the "QCI" value, as specified in 3GPP TS 23.203[ Policy and charging control architecture ]  [48]. The UL/DL MBR and GBR fields are encoded as kilobits per second (1 kbps = 1000 bps) in binary value. For non-GBR bearers, both the UL/DL MBR and GBR should be set to zero. The range of QCI, Maximum bit rate for uplink, Maximum bit rate for downlink, Guaranteed bit rate for uplink and Guaranteed bit rate for downlink are specified in 3GPP TS 36.413[ Evolved Universal Terrestrial Radio Access Network (E-UTRAN); S1 Application Protocol (S1AP) ]  [10]. NOTE: The encoding in 3GPP TS 24.301[ Non-Access-Stratum (NAS) protocol for Evolved Packet System (EPS); Stage 3 ]  [23] and 3GPP TS 36.413[ Evolved Universal Terrestrial Radio Access Network (E-UTRAN); S1 Application Protocol (S1AP) ]  [10] is different from the encoding within this specification.
