Parameter Type Description
<Grac> Number One byte routing area of the GERAN cell in hexadecimal format; FF if not known or not
detectable.
<rxlev> Number GERAN cell Received Signal Strength Indicator (RSSI) index as defined in 3GPP TS
45.008 [28]:
• 0: less than -110 dBm
• 1..62: from -110 to -48 dBm with 1 dBm steps
• 63: -48 dBm or greater
• 255: not known or not detectable
<grr> Number Reserved for future use.
<t_adv> Number Reserved for future use.
<Gspeech_mode> Number Reports the latest obtained value of the GSM speech code. Allowed values:
• 0: GSM Enhanced Full Rate (12.2 kb/s)
• 1: GSM Full Rate (13.0 kb/s)
• 2: GSM Half Rate (5.6 kb/s)
• 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 [113] 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 Primary Scrambling Code; range 0-512, 0 if not known or not detectable.
<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 [106]:
• 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 UTRAN cell Ratio of received energy per PN chip to the total received power spectral
density as defined in 3GPP TS 25.133 [106]:
• 0: less than -24 dB
