Coordinated Node System Selection for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inefficient system selection among nodes in wireless communication networks leads to excess power consumption and prolonged system selection times due to independent node operations, lacking efficient mechanisms for sharing system scan results across nodes.
Innovation Solution
A method where nodes determine their role within a subset of nodes, with authorized nodes performing system scans on multiple Radio Access Technologies (RATs and transmitting results to others, allowing the set of nodes to decide whether to switch between RATs based on scan results, thereby optimizing system selection and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each node independently performs system scans on multiple RATs, then system selection reliability is improved, but power consumption increases and system selection time increases
Solution Approach 1:
The patent segments the node population into two distinct groups: scanning nodes that perform system scans on multiple RATs, and non-scanning nodes that rely on scan results from scanning nodes. This segmentation allows the system to maintain reliable system selection through dedicated scanning nodes while avoiding the excessive power consumption that would result from every node independently scanning all RATs.
2Reliability
If each node independently performs system scans on multiple RATs, then system selection reliability is improved, but system selection time increases
Solution Approach 1:
Scanning nodes perform system scans on multiple RATs in advance and store the scan results. When non-scanning nodes need to perform system selection, they can directly utilize these pre-acquired scan results without having to conduct their own time-consuming scans, thereby significantly reducing system selection time while maintaining reliability.
3Use of energy by moving object
If nodes share system scan results, then power consumption is reduced, but device complexity increases
Solution Approach 1:
Each node autonomously determines whether it should function as a scanning node or a non-scanning node based on its own characteristics and the needs of the network. This self-service approach allows nodes to independently make decisions about their role in the system, reducing the need for complex centralized coordination mechanisms while still enabling effective result sharing and power savings.

AI summary
Methods, computer-readable medium, and apparatus are described for coordinating system selection among a set of nodes. The described aspects include determining that a node is part of a subset of nodes, wherein each node in the subset of nodes performs one or more system scans for a set of nodes that includes the subset of nodes, performing the one or more system scans by the node on one or more Radio Access Technologies (RATs) in response to determining that the node is part of the subset of nodes, obtaining one or more system scan results from the one or more system scans on the one or more RATs, and transmitting the one or more system scan results to the set of nodes.
