1. When mode is 2, auto URCs are reported per 5 seconds.
2. The <lac> and <cellid> parameters in hex format, other parameter is in decimal format.
3. If the cell information is not detected, the parameter is replaced by ‘x’ char.
4. If the detecting is not expert mode, the <tch>, <ts>, maio>, <hsn>, <ta>, <rxq_sub> and <rxq_full>
parameter do not display the value of the parameter and replaced by ‘x’ char.
5. Duration of the network connecting, if the hopping frequency is supported by the network, so the
channel of TCH is instable. Using the ’h’ figure <tch> under this mode.
6. Under expert mode, when the <c1> and <c2> of the serving cell cannot be updated. Using the ‘-1’
figure to display the illegal value. At the same time, the <txp> and <rla> parameter cannot be
updated in a certain condition, all the same holding the value of idle mode. This is because ME
cannot be updated in this mode and cannot update the selection of cell and reselection of the
parameter. When the connecting is over, mobile device goes back idle mode and gives out the
correct value.
7. If TA can report the information of the neighboring cell, the URCs of six neighboring cell should be
reported. If some cells cannot be measured, the ‘x’ char will be filled in the parameter of these cells.
8. Under the special mode, the <c1> and <c2> parameters of the neighboring cell may be measured,
then will report an unmeaning value. When the <mcc>, <mnc>, <lac> and <cellid> parameter of the
neighboring cell cannot be measured, the 'x' char will be filled in these parameters of all the six cells.
9. The command does not report the RX level and the RX quality. The AT+CSQ command can be used
to query the values of RX level and RX quality.
10. The AT+QSPCH command can be used to re-query the type of the voice channel during calling (FR,
HR, EFR, AMR_FR, AMR_HR).
<c2> C2 value
<txp> Transmit power maximum access a CCH
<rla> Receive level access minimum
<ts> Timeslots
<maio> MAIO value
<hsn> HSN value
<tch> ARFCN of TCH, ‘h’ figure hopping
<ta> Timing Advance, range 0~63
<rxq_sub> RX quality (sub), range 0-7
<rxq_full> RX quality (full), range 0-7
<ncell> Number of neighboring six cell ID 1~6
<arfcn> Absolute radio frequency channel number
