Hello,
I am using quectel-CM with RM520N-GL modem. I have successfully established PDU sessions with the Slice of my choice. I use AT+CGDCONT? for creating profiles:
AT+CGDCONT?
+CGDCONT: 1,“IPV4V6”,“default”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 2,“IPV4V6”,“ims”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 3,“IPV4V6”,“sos”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,1,“”,0
+CGDCONT: 4,“IPV4V6”,“internet_EMBB00000B”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,0,“01.00000B”,0
+CGDCONT: 5,“IPV4V6”,“internet_EMBB00000C”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,0,“01.00000C”,0
and sudo ./quectel-CM -n for activating the profile of my choice.
While testing, I tried activating a non-existing PDU Profile with CID 7, believing that the connection would fail. But on the contrary, the modem connected to the network with a DNN and a slice and a PDU Profile was created:
+CGDCONT: 7, “IPV4V6”, " “, “0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,” ",0
which can NOT be deleted.
I have tried:
AT+CGDCONT=7 and i get an ERROR message.
I also tried to create a PDU Profile with CID 7: AT+CGDCONT=7,“IPV4V6”,“internet” which was successfully created:
AT+CGDCONT?
+CGDCONT: 1,“IPV4V6”,“default”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 2,“IPV4V6”,“ims”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 3,“IPV4V6”,“sos”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,1,“”,0
+CGDCONT: 4,“IPV4V6”,“internet_EMBB00000B”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,0,“01.00000B”,0
+CGDCONT: 5,“IPV4V6”,“internet_EMBB00000C”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,0,“01.00000C”,0
+CGDCONT: 7, “IPV4V6”, " “, “0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,” ",0
+CGDCONT: 7, “IPV4V6”, "internet “, “0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,” ",0
and then deleted it with AT+CGDCONT=7. So after this:
AT+CGDCONT?
+CGDCONT: 1,“IPV4V6”,“default”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 2,“IPV4V6”,“ims”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 3,“IPV4V6”,“sos”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,1,“”,0
+CGDCONT: 4,“IPV4V6”,“internet_EMBB00000B”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,0,“01.00000B”,0
+CGDCONT: 5,“IPV4V6”,“internet_EMBB00000C”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,0,“01.00000C”,0
+CGDCONT: 7, “IPV4V6”, " “, “0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,” ",0
It seems like the profile +CGDCONT: 7, “IPV4V6”, " “, “0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,” ",0 that was created beacuse of the quectel-CM command can not be deleted or modified.
I also restarted the modem.
What can I do to delete this profile ??? And why did this happen ???
Thank you in advance!
