Parameter Type Description
• 3..10: AMR NB FR (from 4.75 kb/s to 12.2 kb/s) the value indicates the first codec
type chosen from the DUT; see the corresponding value of <Wspeech_mode>
parameter for the baud rate mapping
• 3..8: AMR NB HR (from 4.75 kb/s to 7.95 kb/s) the value indicates the first codec type
chosen from the DUT; see the corresponding value of <Wspeech_mode> parameter
for the baud rate mapping
• 11..13: AMR WB FR (from 6.60 kb/s to 12.65 kb/s) the value indicates the first
codec type chosen from the DUT; see the corresponding value of <Wspeech_mode>
parameter for the baud rate mapping
• 255: not known or not detectable
See 3GPP TS 26.201 [91] for more details on GSM codecs used during a voice call
In case a set of speech codecs is assigned by the network, then the parameter
reports the lowest one and this one is not necessary the one used.
<uarfcn> Number UTRAN Absolute Radio Frequency Channel Number (UARFCN); the range is 1537-10
838, 65535 if not known or not detectable.
<Wband> Number UTRAN band:
• 1: band 1 (2 GHz)
• 2: band 2 (1900 MHz)
• 4: band 4 (2100 MHz)
• 5: band 5 (800 MHz)
• 8: band 8 (900 MHz)
• 255: not known or not detectable
<WcellId> Number UTRAN CI (cell identifier) in hexadecimal format; the range is 0h-FFFFFFFh (28 bits),
0000000 if not known or not detectable.
<Wlac> Number Two bytes location area of the UTRAN cell in hexadecimal format; FFFF if not known
or not detectable.
<Wrac> Number One byte routing area of the GERAN cell in hexadecimal format; FF if not known or not
detectable.
<scrambling_code> Number See <scrambling_code>.
<Wrrc> Number 3G RRC state:
• 0: idle
• 1: URA_PCH
• 2: CELL_PCH
• 3: CELL_FACH
• 4: CELL_DCH
• 255: not known or not detectable
<rssi> Number UTRAN cell Received Signal Strength Indicator as defined in 3GPP TS 25.133 [84]:
• 0: less than -100 dBm
• 1..75: from -100 to -25 dBm with 1 dBm steps
• 76: -25 dBm or greater
• 255: not known or not detectable
<ecn0_lev> Number See <ecn0_lev>.

• 8: AMR NB (7.95 kb/s)
• 9: AMR NB (10.2 kb/s)
• 10: AMR NB (12.2 kb/s)
• 11: AMR WB (6.60 kb/s)
• 12: AMR WB (8.85 kb/s)
• 13: AMR WB (12.65 kb/s)
