Radio Resource Management Device Channel Scanning Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, existing channel scan methods are inefficient as they do not effectively consider channel shortages and dynamic changes in communication probabilities between mobile stations and base stations, leading to suboptimal communication establishment and increased scanning time.
Innovation Solution
A management device acquires parameters to predict resource shortages at base stations and generates priority-level information for channel usage, which is transmitted to terminal devices to guide efficient channel scanning and resource selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile station performs a channel scan by attempting reception while changing channels to search for base stations, then the mobile station can find available base stations, but the scanning time becomes excessively long when the number of channels is large
Solution Approach 1:
The management device performs preliminary actions by acquiring parameters that predict resource shortages at base stations, generating priority-level information before the terminal device performs channel scanning. This pre-computed priority information guides the terminal device to scan channels in an optimized sequence, reducing scanning time while ensuring reliable channel discovery.
2Productivity
If the mobile station determines scanning sequence based on distances to base stations, then the scanning efficiency is improved, but channel shortages at base stations are not considered
Solution Approach 1:
The management device provides feedback to terminal devices about the resource status and priority levels at base stations. This feedback mechanism allows terminal devices to adjust their channel scanning strategy based on real-time or near-real-time information about base station resource availability, thereby improving both scanning efficiency and the reliability of communication establishment.
3Productivity
If the mobile station stores positional information and channel information of base stations in advance, then the scanning process is optimized, but the information becomes outdated when base station arrangements or channels are changed
Solution Approach 1:
The management device enables a self-service mechanism where terminal devices automatically receive updated priority-level information from the management device. This eliminates the need for manual updates of stored base station information and allows terminal devices to adapt to changes in base station arrangements or channel allocations without human intervention, maintaining both optimization and adaptability.
4Quantity of substance
If the number of base stations increases to handle more mobile stations, then the system capacity is improved, but resource shortages occur more frequently at individual base stations
Solution Approach 1:
The management device segments the channel scanning process by assigning different priority levels to different channels based on base station resource status. This segmentation allows terminal devices to focus scanning efforts on high-priority channels first, effectively managing system capacity while mitigating resource shortage issues at individual base stations through intelligent resource allocation.

AI summary
An acquirer acquires parameters that correspond to a plurality of base station devices using a resource for communication with a terminal device and can be used for predicting a shortage of a resource of each base station device. A generator generates information relating to a priority level of a resource desired to be used by a terminal device connected to one of the plurality of base station devices in accordance with the parameters acquired by the acquirer. A transmitter transmits the information generated by the generator.
