The Short Message Service (SMS) and Unstructured Supplementary
Service Data (USSD) of mobile cellular networks is frequently used in
Machine-To-Machine (M2M) communications, such as for telematic
devices. The service offers small packet sizes and high delays just
as other typical low-power and lossy networks (LLNs), i.e. 6LoWPANs.
The design of the Constrained Application Protocol (CoAP), that took
the limitations of LLNs into account, is thus also applicable to
telematic M2M devices. The adaptation of CoAP to the SMS or USSD
transport mechanisms and the combination with IP transported over
cellular networks is described in this document.
