Figure 8.2.9-1: GBR
The UL/DL GBR fields shall be encoded as kilobits per second (1 kbps = 1000 bps) in binary value. The UL/DL GBR fields may require converting values in bits per second to kilobits per second when the UL/DL GBR values are received from an interface other than GTPv2 interface. If such conversions result in fractions, then the value of UL/DL GBR fields shall be rounded upwards. The range of UL/DL GBR is specified in 3GPP TS 36.413 [10].
NOTE: The encoding is aligned on the encoding specified in 3GPP TS 29.274 [9].
