 |
|
Is there any way to have some sort of QOS program that will detect an incoming call, then turn on its QOS (ie: slowing down downloads) when a incoming call comes in/call in progress?
Right now my setup is USB modem connect to PC, then PC out to Ethernet to VOIP adapter via ICS sharing.
Since I can't use WAN on the voip.. and no cradlepoint either..
Does these kind of commands work on the EVDO novatel?
| Quote: | 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 the connection can be accepted. Let say you set the following QoS window:
MIN 64k (D) 32k (U)
REQ 144k (D) 64k (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 144k - if there wasn't bandwidth avail. the network will try 64k. The "connected rate" will always show 384k (for my memory using windows - Mac and Linux might varry)
Here is what the NovaTel card's help show the commands as :
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 384k]
Init5 = AT+CGEQMIN=1,4,64,384,64,384
Init6 = AT+CGEQREQ=1,4,64,384,64,384
[Dialer 144k]
Init5 = AT+CGEQMIN=1,4,64,144,64,144
Init6 = AT+CGEQREQ=1,4,64,144,64,144
[Dialer 64k]
Init5 = AT+CGEQMIN=1,4,64,64,64,64
Init6 = AT+CGEQREQ=1,4,64,64,64,64
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 fifth os max. downlink - in kbits/s
and last but not least is guaranteed downlink, in kbits/s
I hope this helps. I have only been able to play with the QoS settings using the Option and Novatel cards. Things might be diff. using the E1000 but I can't see how. Talking of which Waansin, did you get the E1000 upgraded (software) ?
