Small Data Packet Transmission Mechanism for IoT Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications technology networks, especially in IoT, terminal devices face inefficiencies in data packet transmission due to excessive system resource usage and low data transmission efficiency when sending small data packets, as they require multiple signaling interactions with network devices for resource configuration and negotiation.
Innovation Solution
A method and system that allow terminal devices to determine whether to use a small data packet transmission mechanism based on conditions such as data size, time, and pre-configured attributes, sending a radio resource control connection request message to the network device, and receiving an indication to either use the small data packet transmission mechanism or switch to an alternative method.

Engineering Contradiction Analysis
1Productivity
If terminal device individually transmits small data packet with multiple signaling interactions for resource configuration and negotiation, then data transmission can be performed, but system resources are excessively occupied and data transmission efficiency is low
Solution Approach 1:
The patent extracts and removes unnecessary signaling interaction steps from the traditional data transmission process. By using pre-configured uplink resources and transmitting data packets directly without individual resource negotiation, the solution eliminates complex signaling procedures while maintaining transmission functionality, thereby improving efficiency and reducing system resource occupation.
Solution Approach 2:
The patent implements preliminary configuration of uplink resources and transmission parameters before actual data transmission. Terminal devices are pre-configured with resource pools, power control parameters, and transmission formats in advance, allowing them to transmit small data packets immediately without real-time resource negotiation, thus reducing signaling overhead and improving transmission efficiency.
2Productivity
If terminal device uses small data packet transmission mechanism to transmit data packet at any time, then data transmission efficiency is improved, but terminal device abuses the mechanism causing excessive resource usage
Solution Approach 1:
The patent implements feedback mechanisms where terminal devices monitor their own transmission behavior and system resource status. Transmission power is dynamically adjusted based on feedback from power control parameters, and devices are guided to use appropriate transmission mechanisms based on data characteristics and system conditions, preventing abuse while maintaining efficiency.
Solution Approach 2:
The patent introduces dynamic control of transmission parameters including power levels, resource selection, and transmission timing. Instead of allowing unrestricted transmission at any time, the system dynamically adjusts transmission characteristics based on current conditions, enabling efficient transmission when appropriate while preventing resource abuse through adaptive parameter modification.
3Reliability
If terminal device performs multiple signaling interactions with network device for resource configuration, then proper resource allocation is achieved, but transmission time is increased
Solution Approach 1:
The patent performs resource configuration and parameter negotiation in advance during initial network attachment or connection establishment. Terminal devices receive pre-configured resource pools, power control parameters, and transmission formats before actual data transmission, eliminating the need for real-time resource negotiation and significantly reducing transmission delay while maintaining allocation accuracy.
Solution Approach 2:
The patent merges multiple signaling interactions into a single comprehensive configuration procedure. Instead of separate negotiations for resources, power control, and transmission parameters, the system combines these into unified pre-configuration messages, reducing the number of interaction steps and minimizing transmission delay while ensuring proper resource allocation.
