Solution Overview
Problem
Current techniques for transmitting small data payloads in Machine Type Communication (MTC) are inefficient and incompatible with emerging broadband wireless access (BWA) networks, leading to increased network load and resource utilization issues.
Innovation Solution
The implementation of specific techniques and configurations within the BWA network, including the use of reference points like T5a/T5b and S6m, and protocols like GTP and MTC-AP, to efficiently manage and transmit small data payloads, such as triggering schemes, interface schemes, and message formats, to minimize network impact and optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current techniques for transmitting small data payloads are used in MTC, then device compatibility is maintained, but network load increases and resource utilization deteriorates
Solution Approach 1:
The patent segments small data transmissions into two distinct paths: control plane signaling for very small payloads and user plane data bearers for larger payloads. This segmentation allows the network to handle different data sizes efficiently, preventing control plane overload while maintaining device compatibility through standardized interfaces.
Solution Approach 2:
The patent introduces an intermediary mechanism (data bearer establishment signaling) that mediates between the control plane and user plane. This intermediary enables small data to be transmitted through the user plane with minimal control plane involvement, reducing network load while maintaining compatibility through standardized signaling procedures.
2Productivity
If small data payloads are transmitted using traditional MTC methods, then data transmission is achieved, but signaling overhead and network resources increase
Solution Approach 1:
The patent applies preliminary action by establishing data bearers in advance during connection setup or idle state transitions. Once bearers are established, small data can be transmitted immediately without additional signaling overhead, as the transmission path is pre-configured and ready for use.
Solution Approach 2:
The patent uses partial action by utilizing only the necessary control plane signaling to establish bearers, then relying on the pre-established user plane for data transmission. This minimizes control plane involvement to the absolute minimum required, reducing signaling overhead while maintaining full data transmission capability.
3Reliability
If small data transmission triggers full connection establishment, then data can be sent reliably, but network delay increases
Solution Approach 1:
The patent performs preliminary actions by establishing data bearers during idle state or connection setup phases. When small data needs to be transmitted, the bearer is already in place, allowing immediate transmission without triggering full connection establishment, thus maintaining reliability while minimizing delay.
Solution Approach 2:
The patent implements dynamic bearer management where bearers can be established, activated, and deactivated based on real-time data transmission needs. This dynamic approach allows the network to maintain bearers for potential small data transmissions without keeping them permanently active, balancing reliability with resource efficiency and reduced latency.

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.
