Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in selecting the optimal number of access nodes for multicast transmissions, leading to suboptimal network resource utilization and service quality, particularly in ensuring minimum signal strength criteria for both wireless devices and access nodes.
Innovation Solution
The system determines first and second signal strength criteria for wireless devices and access nodes, respectively, and selects a minimum number of access nodes that meet these criteria for efficient multicast transmission, optimizing network resources and service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple access nodes are used for multicast transmissions, then service quality and signal coverage are improved, but network resource utilization deteriorates due to suboptimal selection
Solution Approach 1:
The system dynamically changes the parameter of access node selection by determining signal strength criteria for both wireless devices and access nodes, and selecting only those nodes that meet the criteria thresholds. This parameter-based selection optimizes the balance between service quality and network resource utilization by avoiding suboptimal node selections.
2Reliability
If a minimum number of access nodes are selected based on signal strength criteria, then signal-to-noise ratio is improved, but network overhead increases
Solution Approach 1:
The system applies partial action by selecting only the minimum necessary number of access nodes that meet the signal strength criteria, rather than using all available nodes. This approach achieves the required signal-to-noise ratio while minimizing network overhead by avoiding excessive node participation.
3Productivity
If signal strength criteria are determined for both wireless devices and access nodes, then multicast transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary action by determining signal strength criteria for both wireless devices and access nodes before conducting multicast transmissions. This pre-assessment enables efficient node selection and improves multicast transmission efficiency by avoiding unsuitable node combinations, while the criteria determination process is standardized to manage system complexity.

AI summary
In systems and methods of selecting access nodes for broadcast, signal strength metrics are received from a plurality of wireless devices, wherein the signal strength metrics are based on signals received by the plurality of wireless devices from a plurality of access nodes. A first signal strength criteria is determined for each of the wireless devices based on the received signal strength metrics, and wireless devices for which the first signal strength criteria meets a threshold are selected from among the plurality of wireless devices. A second signal strength criteria is determined for each of the plurality of access nodes. A minimum number of the access nodes is selected wherein the second signal strength criteria meets the threshold for each of the selected wireless devices, and a multicast transmission is transmitted from the selected access nodes to the selected wireless devices.
