Query the geolocation grid code received from the network in the last Access Decision
Notification message. The response is of the form:
–MSGEO: <x>,<y>,<z>,<time_stamp>
<x>, <y>, <z> is a geolocation grid code from an earth centered Cartesian coordinate system,
using dimensions, x, y, and z, to specify location. The coordinate system is aligned such that
the z-axis is aligned with the north and south poles, leaving the x-axis and y-axis to lie in the
plane containing the equator. The axes are aligned such that at 0 degrees latitude and 0
degrees longitude, both y and z are zero and x is positive (x = +6376, representing the nominal
earth radius in kilometers). Each dimension of the geolocation grid code is displayed in decimal
form using units of kilometers. Each dimension of the geolocation grid code has a minimum
value of –6376, a maximum value of +6376, and a resolution of 4.
<time_stamp> is assigned
by the A3LA-RM when the geolocation grid code received from the network is stored to the
A3LA-RM internal memory. Current Iridium system time, which is a running count of 90
millisecond intervals, is used for the time stamp. Time stamp is a 32-bit integer displayed in
hexadecimal form.
A.8.76 +CCFC – Call Forward Service
Exec Command:
+CCFC=<reason>,<mode>[,<number>[,<type>[,class>[,<subaddr>[,<satype>[,<ti
me>]]]]]]
This command is based on GSM 07.07 [2] subclause 7.10, and allows control of the call
forwarding supplementary service according to GSM 02.82 [11]. Registration, erasure and
status query are supported. The valid values for the parameters are as follows:
<reason> takes one of the following values:
0
unconditional
1
mobile busy
2
no reply
3
not reachable
4
all call forwarding (refer GSM 02.30 [5])
5
all conditional call forwarding (refer GSM 02.30 [5])
<mode> takes one of the following values:
0
disable (not used in Call Forward)
1
enable (not used in Call Forward)
2
query status
3
registration
4
erasure
<number>: quoted string type phone number of forwarding address. It contains digits only, or
empty string if not applicable.
<type>:
type of address octet in integer format (refer to GSM 04.08 [7] subclause
10.5.4.7); default 145 when dialing string is international number, otherwise 129
<classx>: is a sum of integers each representing a class of information:
