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.
