Command name: +CGDCONT=
[parameter]
Overview
Sets host (APN) accessed when establishing
packet transmission.
Not stored in FOMA terminal’s memory with AT&W
commands. Not reset with AT&F or ATZ commands.
Syntax
+CGDCONT=[<cid>[,“PPP”[,“<APN>”]]]
o
Parameter description
<cid>
*
: 1 to 10
<APN>
*
: Any number
<cid> is a number for managing hosts (APNs)
used for packet transmission, registered in the
FOMA terminal. It can be set between 1 and 10 in
the FOMA. The default settings are
mopera.ne.jp
for <cid>=1 and
mopera.net
for <cid>=3. Set cid
in 2 or 4 to 10. APN is a user-specified character
string for each connection, indicating the host.
Execution example
Command when registering host (APN) name
“abc” (for <cid>=2)
AT+CGDCONT=2,“PPP”,“abc”
o
OK
Operation when parameter is abbreviated
AT+CGDCONT=
Clears all <cid> settings. Resets <cid>=1 and 3
settings to default values.
AT+CGDCONT=<cid>
Clears specified <cid> setting. Resets <cid>=1
and 3 settings to default values.
AT+CGDCONT=?
Displays list of values that can be set.
AT+CGDCONT?
Displays current settings.

Command name: +CGEQMIN= [parameter]
Overview
Registers criterion determining whether to permit
QoS (Quality of Service) sent from the network
when establishing PPP packet transmission.
The command execution examples below
describe the four available setting patterns.
Not stored in FOMA terminal’s memory with
AT&W commands. Not reset with AT&F or ATZ
commands.
Syntax
AT+CGEQMIN=[<cid> [,, <Maximum bitrate UL>
[, <Maximum bitrate DL>]]]
o
Parameter description
<cid>
*
: 1 to 10
<Maximum bitrate UL>
*
: None (initial setting) or 64
<Maximum bitrate DL>
*
: None (initial setting) or 384
<cid> is a number for managing hosts (APNs)
used for packet transmission, registered in the
FOMA terminal. It can be set between 1 and 10 in
the FOMA terminal. The default settings are
mopera.ne.jp
for <cid>=
１
and
mopera.net
for
<cid>=3. Set cid in 2 or 4 to 10.
Maximum bitrate
UL
and
Maximum bitrate DL
set the minimum
uplink and downlink transmission speed (kbps)
between the FOMA and base station. When set to
None
(default setting), all speeds are permitted.
Note that when set to “64”
and “384”, connections
established under these speeds are not
permitted, so packet transmission connection
may not be established.
Execution examples
Set one of the following four patterns. Setting (1)
is the initial setting for all cid.
（１）
Command permitting all uplink/downlink
speeds (for <cid>=2)
AT+CGEQMIN=2
