Aggressive IoT device signaling

Hi all,

As you know, a lot of IoT devices in the industry do not follow GSMA guidelines for device connectivity efficiency. And many business opt for cheaper devices that work just fine. I have seen lot of these cheap devices causing too many signaling (Attach request, create PDP resquest etc). So many that a few devices can create millions of failed requests a month as they keep trying to reconnect.
How can an MNO with no control over the devices (except sim cards) control this signaling storm caused by these aggressive IoT devices?

Your response is highly appreciated.

Thank you.

Very realistic and meaningful question, as some other non-standard device also cause this to telecom NWs causing huge signalling / paging or RACH failures, it can only be done either by standardisation of devices to implement some QCI profiles, which mac series can be registered only, or otherwise Black listing such devices from the Core.

Any other answers would be appreciated.
