<GPS On Need>: Whether to close GPS chip after retrieving GPS position information.
0: Never close GPS chip
1: Close GPS chip after retrieving GPS information every time.
<GSM report>: If GPS fixing for the report message +RESP:GTSOS, +RESP:GTRTL,
+RESP:GTLBC, +RESP:GTTOW and +RESP:GTFRI were failed and the parameter
<GSM report> was set to 1, the terminal reports the message +RESP:GTGSM, including the
information of the service cell and the neighbour cells after those messages if cell‟s
information available. If it was set to 2, the terminal will report the message
+RESP:GTGSM after getting GPS position successfully every time if cell‟s information
available. If it was set to 3, the terminal will report +RESP:GTGSM no matter what result of
getting GPS position every time if cell‟s information available.
0: Not allow the cells‟ information report.
1: Allow the cells‟ information report after failed to get GPS position if cell‟s
information available.
2: Report the message +RESP: GTGSM after getting GPS position successfully

position every time if cell‟s information available.
<Report Composition Mask>: Bitwise report mask to configure the composition of report
message, especially the GPS information composition.
Bit 0 for <Speed>
Bit 1 for < Azimuth >
Bit 2 for <Altitude>
Bit 3 for GSM tower data, including <MCC>, <MNC>, <LAC>, <Cell ID> and the
<reserved> parameter “00”
Bit 4 for <Mileage>
Bit 5 for <Send Time>
Bit 6 for <Device Name>
For each bit, set it to 1 to enable corresponding component in the report, 0 to disable. This
mask is effective to all report messages.
<Power Saving Mode>: Set mode of power saving function. If mode of power saving
function is set to 1, the fixed report, geo-fence and speed alarm report functions are
suspended when the device is at a standstill or the engine is off. If mode of power saving
function is set to 2, it is mostly like mode 1 and the difference is that the fixed report will not
be suspended and the fix and send interval of it will be set to <IGF Report Interval> in
