Base Station WLAN Connection Control via Terminal Failure Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, base stations face challenges in effectively managing connection control when both LTE and WLAN systems are used in parallel, particularly in Dual Connectivity scenarios, as they cannot accurately acknowledge the status of wireless terminals in WLAN communications, leading to inadequate connection management.
Innovation Solution
A base station apparatus and communication apparatus that include means to obtain information on connection failures in WLAN systems and control the connection based on whether the failure is due to suspended communication functions, allowing for appropriate execution of connection control by distinguishing between system failures and functional suspensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station apparatus uses LTE and WLAN systems in parallel for communication, then system capacity and throughput are improved, but the base station cannot accurately acknowledge the status of wireless terminals in WLAN communications, leading to inadequate connection management
Solution Approach 1:
The patent introduces an intermediary mechanism where the terminal device itself reports its connection status and failure causes to the base station. Since the base station cannot directly monitor WLAN connection status, the terminal acts as a mediator to provide accurate status information through uplink reports, enabling the base station to make informed connection control decisions without direct monitoring capability.
2Measurement precision
If the base station apparatus cannot distinguish between system failures and functional suspensions in WLAN communication, then connection control accuracy deteriorates, but implementing distinction requires additional information collection mechanisms
Solution Approach 1:
The patent implements preliminary action by having the terminal device pre-identify and report the cause of connection failures before the base station needs to make connection control decisions. The terminal analyzes whether the failure is due to system issues or functional suspension and communicates this information proactively, allowing the base station to immediately implement appropriate control measures without complex real-time analysis.
3Reliability
If the base station apparatus implements comprehensive connection control in WLAN system, then connection management reliability is improved, but the complexity of control mechanisms increases
Solution Approach 1:
The patent applies self-service by enabling the terminal device to autonomously monitor its own connection status, identify failure causes, and report this information to the base station. This shifts the burden of status monitoring from the base station to the terminal itself, allowing the base station to implement reliable connection control based on accurate terminal-provided information without requiring complex monitoring infrastructure.

AI summary
In a wireless communication system that includes a base station apparatus and a terminal capable of connecting to the base station apparatus in a first system and connecting to another apparatus in a second system, the base station apparatus obtains, when a failure has occurred in connection in the second system between the terminal and the another apparatus, information indicating whether the failure is attributed to suspension of communication functions of the terminal in the second system, and controls connection of the terminal in the second system based on the information.
