Radio Communication Device Load Distribution via Beam Forming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Millimeter wave communication systems face a decrease in communication quality due to local concentration of radio terminals, especially when using multiple access points, as existing techniques fail to effectively manage the distribution of connection destinations, leading to increased load on certain access points and reduced quality.
Innovation Solution
A radio communication device equipped with a communication processor, an information sharer, a switch determiner, and a connection switcher that acquires connection information from other devices, determines whether to switch the connection destination of a radio terminal, and executes a beam forming protocol to switch the connection to a less loaded access point, thereby distributing the load and maintaining communication quality.

Engineering Contradiction Analysis
1Speed
If conventional techniques are used for handover, then connection speed to another access point is improved, but communication quality decreases when local concentration of radio terminals occurs
Solution Approach 1:
The access point performs preliminary actions by acquiring connection information from neighboring access points in advance and storing it locally. This includes obtaining information about connected radio terminals, beam directions, and communication quality metrics. When a radio terminal requests handover, the access point can immediately reference this pre-acquired information to make informed switching decisions without requiring real-time queries to neighboring access points, thus maintaining fast handover while improving communication quality through better-informed decisions.
Solution Approach 2:
The system implements feedback mechanisms where access points actively acquire and monitor connection information from neighboring access points. The access point uses this feedback information to evaluate handover scenarios and determine optimal switching decisions. The feedback loop continues as the access point monitors communication quality and adjusts handover decisions accordingly, ensuring that communication quality is maintained while enabling efficient handover.
2Area of stationary object
If beam forming techniques are used with multiple access points, then communication coverage is improved, but load concentration on certain access points increases
Solution Approach 1:
The system introduces dynamic load management by enabling access points to dynamically switch connected radio terminals to neighboring access points based on real-time conditions. Instead of static assignment, the access point continuously monitors communication quality and load distribution, and dynamically adjusts connections. When an access point detects heavy load or poor communication quality, it can dynamically redirect terminals to less loaded neighboring access points, achieving balanced load distribution while maintaining comprehensive coverage.
Solution Approach 2:
The system segments the service area into multiple access points, each responsible for a specific cell area. The access point acquires connection information from neighboring access points to understand the overall distribution landscape. By segmenting the management function and sharing information across segmented access points, the system achieves coordinated load distribution while maintaining individual access point autonomy in managing their respective cells.
3Productivity
If radio terminals are concentrated in a specific direction within a cell, then beam forming efficiency is improved, but communication quality decreases due to multiplexing requirements
Solution Approach 1:
The access point acts as an intermediary between radio terminals and the beam forming system. It acquires connection information from neighboring access points to understand the overall terminal distribution pattern. Based on this intermediary information, the access point makes informed decisions about which terminals to keep in its cell and which to redirect. This intermediary role allows the system to maintain beam forming efficiency for concentrated terminals while preventing overload by coordinating with neighboring access points.
