2.19 Automatic network reconnection
If the mobile network provider drops the modem from the cellular network due to the
device’s network inactivity, there are available parameters if these are set, then
automatic and periodical connection connection rebuild can be caused. If the network
provider sends a message to the modem that the data connection has been lost, the
connection will be restored automatically. If you do not send a message, you can
choose from these two workarounds to follow:
a.)
Active mode - Use periodical ping, set the ping:
1.
For setting this, set the
Watchdog
parameter group’s ping parameters as
Ping IP-address
,
Number of ping retries
,
Ping wait-time (for reply)
and
Wait-time (for next).
2.
If there is no ping response, it reconnects to the network after the time
interval specified in the
Seconds, gprs connection closed and restored after
this time
parameter.
Attention!
In case of frequent ping using, the data traffic will be higher, but the
chances are higher that the device will remain on the cellular network.
b.)
Passive mode -
If you don’
t use the ping - set the connection retry:
1.
For setting this, use the
Watchdog
parameter group’s
Seconds, gprs
connection closed and restored after this time
parameter.
2.
Here you can define that after the network drops out the modem, how long
does the modem wait before trying to reconnect to the mobile network
again. Ask your mobile provider about the offered settings.
Attention!
If there is less data traffic and there is no ping configured, the
device may not stay on the network for a long time.
