As to GSM network, the paging period time can be calculated with the following formula.
T= 4.615ms × 51 × DRX
As to WCDMA network, the paging period time can be calculated with the following formula.
T= 10ms × 2
DRX
DRX (Discontinuous Reception) is a value from 2 to 9 in GSM network, resulting in paging intervals
470.6ms to 2118.42ms, and a value from 6 to 9 in WCDMA network, resulting in paging intervals from
640ms to 5120ms.
3.17. Behavior of the RI
You can use command
AT+QCFG=“risignaltype”, “physical”
to configure RI behavior:
No matter which port URC is presented on, URC will trigger the behavior on RI pin.
URC can be output from UART port, USB AT port and USB modem port by command
AT+QURCCFG
.
The default port is USB AT port.
In additional, RI behavior can be configured flexible. The default behavior of the RI is shown as below.

RI keeps high level.
URC
RI outputs 120ms low pulse when new URC returns.
The RI behavior can be changed by command
AT+QCFG=“urc/ri/ring”
