Base Station Wireless LAN Switching Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current switching processes between mobile communication networks and wireless LANs are inefficient as radio terminals often send connection requests to unwanted access points, leading to wasted requests and unnecessary switching back to mobile communication networks when the wireless LAN access points refuse connections.
Innovation Solution
Radio terminals autonomously determine switching based on predefined determination parameters without direct base station instruction, allowing them to send connection requests to access points, and access points can request removal from the base station's list if they do not wish to handle the connection, thereby avoiding unnecessary switching.

Engineering Contradiction Analysis
1Productivity
If radio terminals autonomously determine switching based on determination parameters, then switching efficiency is improved, but connection requests may be sent to access points that refuse connections, causing wasted requests
Solution Approach 1:
The access point performs preliminary action by transmitting its refusal status to the base station before receiving connection requests. The base station then uses this information to prevent the radio terminal from sending connection requests to access points that would refuse them, thereby avoiding wasted requests while maintaining autonomous switching efficiency.
Solution Approach 2:
The access point provides feedback to the base station about its connection acceptance status. The base station uses this feedback information to control whether the radio terminal sends connection requests to specific access points, creating a feedback loop that prevents wasted connection attempts while preserving autonomous switching benefits.
2Productivity
If access points can refuse connections, then access point load management is improved, but the switching process complexity increases
Solution Approach 1:
The base station acts as an intermediary between the access point and the radio terminal. The access point communicates its load status and connection refusal status to the base station, which then controls the radio terminal's connection requests. This intermediary approach allows access points to manage their load without directly increasing the complexity of the switching process between access points and terminals.

AI summary
A base station according to an embodiment is a base station configured to constitute a mobile communication network. The base station comprises: a transmitter configured to transmit first information to a radio terminal controlled by the base station itself, the first information including one or more identifiers indicating a wireless LAN access point that is a candidate of a standby target or a connection target when a radio terminal switches the standby target or the connection target from the mobile communication network to a wireless LAN; and a receiver configured to receive a removal request for removing at least one or more predetermined identifiers from the first information, from the wireless LAN access point or a node configured to control the wireless LAN access point.
