Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous radio communication networks, the efficiency of radio resource assignment and usage between terminals and base stations is insufficient due to communication interference and the need for frequent reassignment, especially when different radio specifications and cell radii are mixed, leading to suboptimal resource utilization.
Innovation Solution
A radio communication terminal with a processor and antenna that uses usage history information to locate the most suitable base station and assign radio frequencies for user data communication, reducing interference by selecting frequencies with high usage history and priority, thereby improving resource allocation efficiency.

1Productivity
If traditional active scan or passive scan is used to search for radio base station and radio channel, then base station selection can be performed, but the efficiency of radio resource assignment and usage is insufficient due to communication interference and frequent reassignment
Solution Approach 1:
The terminal performs preliminary scanning to collect usage history information of radio frequencies for each base station before actual communication. This preliminary action stores frequency usage patterns that enable more efficient and reliable resource assignment during subsequent communications, reducing both interference and reassignment needs.
Solution Approach 2:
The system utilizes usage history information as feedback to dynamically select radio frequencies. The terminal refers to accumulated usage history data to make informed frequency selection decisions, continuously improving resource assignment efficiency while maintaining communication stability through adaptive frequency choice.
2Productivity
If radio frequencies are assigned without considering usage history, then assignment process is simple, but communication interference occurs and frequent reassignment is needed
Solution Approach 1:
Usage history information serves as feedback that informs frequency selection decisions. The terminal analyzes accumulated usage patterns to identify frequencies with lower interference potential, thereby improving resource utilization efficiency while reducing communication interference through data-driven frequency assignment.
Solution Approach 2:
The system changes the frequency selection parameter from random or simple assignment to usage-history-based selection. By incorporating usage history data into the frequency selection process, the system dynamically adjusts frequency choices to optimize resource utilization and minimize interference.
3Productivity
If usage history information is collected and analyzed for frequency assignment, then resource assignment efficiency improves, but processing time and power consumption increase
Solution Approach 1:
Usage history information is collected in advance during preliminary scanning phases, separating the data collection burden from the frequency assignment moment. This preliminary action allows the terminal to build a repository of usage patterns that can be quickly queried during actual communication, improving assignment efficiency without sustained high power consumption.
Solution Approach 2:
The terminal collects usage history information selectively rather than continuously monitoring all frequencies at full capacity. By performing partial scanning and collecting only necessary usage history data, the system achieves improved frequency assignment efficiency while keeping power consumption within acceptable limits.
