Priority alarm messages for MTC in industry applications require guaranteed delays of a few dozen milliseconds only, with super-critical applications even calling for below-10-ms access. With the best state-of-the-art cellular systems barely able to meet below-50-ms delays, in this article we propose some important improvements to the 3GPP MTC access procedure allowing a significantly performance boost for alarm messages. Notably, the first method encompasses an SMS-like approach where the alarm is transmitted in a secure and backward-compatible form over the connection-establishing access channel, thus allowing the data transmission to be terminated significantly earlier and to support emerging critical alarm messages. The second method uses a secure and previously agreed sequence of random access codes to convey super-critical alerts within a few milliseconds, and is thus able to support emergency alarm messages. Both methods not only achieve control-compliant access delays but are also highly energy efficient, thus allowing long battery lifetimes and hence quicker uptake by the industry.

Abstract

Priority alarm messages for MTC in industry applications require guaranteed delays of a few dozen milliseconds only, with super-critical applications even calling for below-10-ms access. With the best state-of-the-art cellular systems barely able to meet below-50-ms delays, in this article we propose some important improvements to the 3GPP MTC access procedure allowing a significantly performance boost for alarm messages. Notably, the first method encompasses an SMS-like approach where the alarm is transmitted in a secure and backward-compatible form over the connection-establishing access channel, thus allowing the data transmission to be terminated significantly earlier and to support emerging critical alarm messages. The second method uses a secure and previously agreed sequence of random access codes to convey super-critical alerts within a few milliseconds, and is thus able to support emergency alarm messages. Both methods not only achieve control-compliant access delays but are also highly energy efficient, thus allowing long battery lifetimes and hence quicker uptake by the industry.
