UC20 QENG syntax

Hi, we have several uc20 in the field and we are trying to get more info relating to the signal levels, relating signals rscp and ecio.
The manual says to look at the function AT+QENG, however there is no documentation of that function anywhere.
We get this answer, which we don’t know how to interpret:
“\r\n+QENG: "servingcell","NOCONN","3G",730,01,34C3,52D0A33,3073,312,-68,-70,12,24,41,64,-,-,-,-,-,"-",-\r\n\r\nOK\r\n”

Does anyone have more info on what is each field?

Thanks
