*Quality of Service (QOS) is a special parameter of a CID which consists of several parameters itself.<br />
The QOS consists of<br />
The precedence class<br />
The delay class<br />
The reliability class<br />
The peak throughput class<br />
The mean throughput class<br />
And is decided in “requested QOS” <strong>and</strong> “minimum acceptable QOS”.<br />
All parameters of the QOS are initiated by default to the “network subscribed value (=0)” but the<br />
QOS itself is set to be undefined. To define a QOS use the <strong>AT</strong>+CGQREQ or <strong>AT</strong>+CGQMIN<br />
comm<strong>and</strong>.<br />
Overwrites the precedence class of<br />
QOS of CID 1 <strong>and</strong> sets the QOS of<br />
CID 1 to be present<br />
<strong>AT</strong>+CGQREQ=1,2 OK<br />
Response: all QOS values of CID 1<br />
Are set to network subscribed except<br />
<strong>AT</strong>+CGQREQ? +CGQREQ:1,2,0,0,0,0<br />
precedence class which is set<br />
to 2<br />
OK<br />
<strong>Set</strong> the QOS of CID 1 to not present.<br />
Once defined, the CID it can be<br />
activated.<br />
<strong>AT</strong>+CGQREQ=1 OK
