How long will a downlink message stay in the network queue?
-
I was wondering how long a downlink message will stay in the network queue.
Or are messages kept there forever, if a device never sends another uplink? -
In case of UDP our middleware manages for each device an out-queue for downlink messages.
The max. size of the queue is 10 messages.
After an uplink messages has been received all queued downlink messages are delivered to the device 1 messages / sec.
If the devices never sends an uplink messages the downlink message stays in the out-queue for ever.
If the device is deleted the out-queue for downlink messages is deleted as well.Hope this info helps.

@roalnd-baldin Thanks for your clear answer.
Happy to hear that the message will stay in the out-queue forever. -

This is valid only for non eDRX downlink messages. eDRX messages are sent directly into the network and will be buffered by the mobile network until the device is available.
Unfortunately I don’t know how long the downlink message is buffered by the mobile Telekom network
