Network Node Impact Information Exchange for Traffic Offloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular networks, determining the energy cost of a network node for traffic offloading is challenging due to the impact of other network nodes on measurement accuracy, especially when concurrent offloading actions occur.
Innovation Solution
An apparatus and method for a network node that sends a message to a target network node requesting measurement information and impact information on the impact of other network nodes on the energy cost measurement, allowing for informed actions related to traffic offloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If impact information is collected and exchanged between network nodes, then measurement precision of energy cost is improved, but device complexity increases
Solution Approach 1:
The impact information is segmented into distinct components: impact level (quantifying the impact magnitude), impact indicator (identifying the impacting network node), and duration (indicating the impact period). This segmentation allows the target network node to process and report impact information systematically without overwhelming complexity, while still achieving precise energy cost measurements.
Solution Approach 2:
The requesting network node receives impact information from the target network node and uses this feedback to adjust its energy cost calculations. The feedback mechanism includes the target network node reporting impact levels and durations, which the requesting node then factors into its decision-making process for traffic offloading, thereby improving measurement precision through iterative refinement.
2Productivity
If impact information is sent immediately or concurrently with measurement information, then productivity of traffic offloading decisions is improved, but loss of time in processing increases
Solution Approach 1:
The target network node prepares impact information in advance or simultaneously with the measurement process. By configuring the node to send impact information substantially immediately after acquisition or concurrently with measurement information, the system eliminates delays in the decision-making process, thereby improving productivity without significant time loss.
Solution Approach 2:
The system dynamically adjusts the timing of impact information transmission based on operational needs. The configuration information allows flexible timing options (immediate, concurrent, or after completion), enabling the system to optimize between processing time and decision speed according to real-time network conditions and traffic offloading requirements.
