Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current MTC techniques are used for small data transmission, then device communication capability is maintained, but network load increases and resource utilization deteriorates
Solution Approach 1:
The patent segments the small data transmission process into distinct phases: data generation at MTC device, triggering mechanism activation, network node processing (MME/SGSN), and data delivery. This segmentation allows each node to handle only necessary operations, reducing overall network load while maintaining communication reliability.
Solution Approach 2:
The patent implements preliminary actions through trigger mechanisms that are pre-configured in the network. When specific conditions are met (e.g., data buffer threshold), pre-defined triggering actions are automatically executed, eliminating the need for continuous network monitoring and reducing signaling overhead.
2Adaptability or versatility
If traditional signaling protocols are used, then protocol compatibility is maintained, but signaling delays increase
Solution Approach 1:
The patent extracts the triggering function from traditional signaling protocols and implements it as a separate, dedicated mechanism. This allows the triggering process to operate independently with optimized timing, reducing signaling delays while maintaining compatibility with existing protocols through standardized interfaces.
Solution Approach 2:
The patent introduces intermediary nodes (MTC-IWF, MME, SGSN) that mediate between MTC devices and the core network. These intermediaries buffer and manage signaling traffic, allowing asynchronous processing that reduces delays while maintaining protocol compatibility through standardized message formats.
3Device complexity
If standard resource allocation is used, then network management simplicity is maintained, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent applies local quality by implementing specialized resource allocation rules specifically for MTC small data transmissions. Different resource pools, scheduling priorities, and allocation algorithms are applied locally to MTC traffic versus traditional mobile data, optimizing resource utilization without complicating overall network management through targeted configurations.

AI summary
Embodiments of the present disclosure describe techniques and configurations for triggering transmission of data payloads in a wireless communication network. An apparatus may include one or more computer-readable media having instructions and one or more processors coupled with the one or more computer-readable media and configured to execute the instructions to implement an interworking function (IWF) to receive, from a Machine Type Communication (MTC) server, a trigger request to trigger sending of a data payload over a wireless communication network, the data payload being smaller than a preconfigured threshold, and send, in response to the trigger request over a reference point to a module including a Mobility Management Entity (MME) or a Serving GPRS (General Packet Radio Service) Support Node (SGSN), a trigger notification to trigger sending of the data payload over the wireless communication network.
