Communication Terminal Load Balancing via Connection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in distributing communication terminals across multiple radio communication modules, leading to imbalances that deteriorate radio performance and user convenience due to uneven load distribution and processing times.
Innovation Solution
A control device and method that manages the connection of communication terminals to radio communication modules by using a processor to determine whether to permit connections based on the number of terminals connected to each module, employing a MAC address filter and connection management tables to balance the load and prevent excessive unevenness in connections.

Engineering Contradiction Analysis
1Productivity
If complex processing is used to distribute load after authentication, then communication terminals can be distributed across modules, but processing time increases and user convenience deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-setting identical connection restrictions (security settings) on all radio communication modules before authentication occurs. This allows terminals to be distributed across modules during the authentication phase itself, rather than requiring complex post-authentication processing. The load distribution is achieved in advance, eliminating the need for time-consuming complex processing later.
2Adaptability or versatility
If the same connection restriction setting is applied to all access points, then roaming is realized, but terminal distribution becomes unbalanced and radio performance deteriorates
Solution Approach 1:
The patent applies local quality by allowing each radio communication module to have the same security settings (maintaining roaming capability) while introducing local variation through the access point's ability to selectively control which terminals can connect to which modules. The control section of the access point monitors connection counts per module and dynamically adjusts connection permissions locally, creating balanced terminal distribution while preserving overall roaming functionality.

AI summary
A control device includes a memory that stores instructions and a processor that executes the instructions. The instructions cause the processor to perform: controlling, based on a first number of communication terminals to which a first module performs radio communication and a second number of communication terminals to which a second module performs radio communication, whether to permit the communication terminal having made a request for connection to the first module to connect to the first module or not.
