At command for QoS

From: http://mybroadband.co.za/vb/archive/index.php/t-18042.html

 

There are 4 commands used to set the QoS:

At + cgeqmin
At + cgeqreq
At + cgqmin
At + cgqreq

These commands set the QoS "window" that will be used to check if
Connection can be accepted. Let say you set the following QoS window:

Min 64 K (d) 32 K (u)
REQ 144 K (d) 64 K (u)

The network will then accept the connection using req, since there is
Bandwidth avail. etc. But notice that the download speed * will * be
Limited 144 K-if there wasn't bandwidth avail. The network will try
64 K. The "connected rate" will always show 384 K (for my memory using
Windows-Mac and Linux might varry)

Here is what the Novatel card's help show the commands:

At + cgeqmin =?
+ Cgeqmin:
"Ip", (0-4), (0-384), (0-384), (0-384), (0-384), (0-2 ), (0-1520), ("0e0", "1e1", "1E2", "7e3", "1e3", "1e4", "1e5", "1e6 "), ("0e0", "5e2", "1E2", "5e3", "4e3", "1e3 ",")
+ Cgeqmin:
"PPP", (0-4), (0-384), (0-384), (0-384), (0-384), (0-2 ), (0-1520), ("0e0", "1e1", "1E2", "7e3", "1e3", "1e4", "1e5", "1e6 "), ("0e0", "5e2", "1E2", "5e3", "4e3", "1e3 ",)

At + cgeqreq =?
+ Cgeqreq:
"Ip", (0-4), (0-384), (0-384), (0-384), (0-384), (0-2 ), (0-1520), ("0e0", "1e1", "1E2", "7e3", "1e3", "1e4", "1e5", "1e6 "), ("0e0", "5e2", "1E2", "5e3", "4e3", "1e3 ",")
+ Cgeqreq:
"PPP", (0-4), (0-384), (0-384), (0-384), (0-384), (0-2 ), (0-1520), ("0e0", "1e1", "1E2", "7e3", "1e3", "1e4", "1e5", "1e6 "), ("0e0", "5e2", "1E2", "5e3", "4e3", "1e3 ",)

At + cgqmin =?
+ Cgqmin: "ip", (0-3), (0-4), (0-5), (0-9), (0-18, 31)
+ Cgqmin: "PPP", (0-3), (0-4), (0-5), (0-9), (0-18, 31)

At + cgqreq =?
+ Cgqreq: "ip", (0-3), (0-4), (0-5), (0-9), (0-18, 31)
+ Cgqreq: "PPP", (0-3), (0-4), (0-5), (0-9), (0-18, 31)

I don't use the + cgqreq commands since they require wierd profiles from
The UMTS standard. luckly for us, we don't have to enter the whole
String, since the ones you leave out will go to default.

Here are my commands for the speed selection:

[Dialer 384 K]

Init5 = at + cgeqmin = 64,384, 64,384
Init6 = at + cgeqreq = 64,384, 64,384

[Dialer 144 K]

Init5 = at + cgeqmin = 64,144, 64,144
Init6 = at + cgeqreq = 64,144, 64,144

[Dialer 64 K]

Init5 = at + cgeqmin =, 64, 64, 64
Init6 = at + cgeqreq =, 64, 64, 64

The first Param. selects the IP profile (at + cgdcont = 1, "ip "...).
The second one selects the type of service (0-Conv, 1-stream, 2-
Interactive, 3-background, 4-sub. Value/network assigned)
It doesn't pay to try and select the other type of services since you
Are using data, which is (drum roll) Number 3 and the connection will
Not be made.
The third is Max. Uplink-In kbits/s
The forth is guaranteed uplink-In kbits/s
The maximum th OS Max. downlink-In kbits/s
And last but not least is guaranteed downlink, in kbits/s
