See 3GPP TS 26.201 [113] for more details on UMTS 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.
<earfcn> Number E-UTRAN Absolute radio frequency channel number; the range is 0-6449, 65535 if
not known or not detectable.
<Lband> Number E-UTRAN band (see 3GPP TS 36.101 Table 5.5-1 [99]); the range is 0-44, 255 if not
known or not detectable.
<ul_BW> Number Number of Uplink Resource Blocks (see 3GPP TS 36.101 Table 5.6-1 [99]), 255 if not
known or not detectable.
<dl_BW> Number Number of Downlink Resource Blocks (see 3GPP TS 36.101 Table 5.6-1 [99]), 255 if not
known or not detectable.
<tac> Number E-UTRAN cell Tracking area code in hexadecimal format; the range is 0h-FFFFh (2
octets), FFFF if not known or not detectable.
<LcellId> Number E-UTRAN CI (cell identifier) in hexadecimal format; the range is 0h-FFFFFFFh (28
bits), 0000000 if not known or not detectable.
<P-CID> Number E-UTRAN cell Physical Cell ID; the range is 0-503, 65535 if not known or not
detectable.
<mTmsi> Number 4 bytes MME Temporary Mobile Subscriber Identity in hexadecimal format; 0000000
0 if not known or not detectable.
<mmeGrId> Number 2 bytes MME Group Identifier in hexadecimal format; FFFF if not known or not
detectable.
<mmeCode> Number 1 byte MME Code in hexadecimal format; FF if not known or not detectable.
<rsrp> Number Reference Signal Received Power (RSRP) as defined in 3GPP TS 36.133 [105]:
• 0: less than -140 dBm
• 1..96: from -140 dBm to -44 dBm with 1 dBm steps
• 97: -44 dBm or greater
• 255: not known or not detectable
<rsrq> Number Reference Signal Received Quality (RSRQ) as defined in 3GPP TS 36.133 [105]:
• 0: less than -19.5 dB
• 1..33: from -19.5 dB to -3 dB with 0.5 dB steps
• 34: -3 dB or greater
• 255: not known or not detectable
<Lsinr> Number E-UTRAN Signal to Interference and Noise ratio in dB. The range goes from -15,88 to
15,88; 255 if not known or not detectable.
<Lrrc> Number 4G RRC state:
• 0: null
