full_form: Message Queuing Telemetry Transport
context: in OneM2M protocol consisting of request and response primitives, is to be mapped to CoAP methods or MQTT payload. As illustrated in Figure 5.5.2-1 (UE and AKMA functions can be both originators or receivers depending on interaction direction, the figure depicts UE sending requests to AKMA functions as an example), while UE sends requests to AKMA functions, it implements the binding function to map request messages to specific MQTT or CoAP messages for transferring. Upon receiving MQTT or CoAP messages, AKMA functions unbind the messages from specific transport protocol and execute the subsequent actions. NOTE: This solution is incomplete due to lack of design on fitting protocol binding mechanisms into AKMA architecture, thus itâs not taken into consideration while concluding key issue#2.
description: MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for machine-to-machine communication. It facilitates efficient data transfer between devices, making it particularly suitable for IoT applications.
explanation: The text describes MQTT as a 'messaging protocol' used for 'machine-to-machine communication', which are defining characteristics of a telecommunications protocol.
