Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless devices prioritize LTE connections over Wi-Fi in coexistence environments due to LTE's aggressive connection mechanism, leading to increased costs, battery consumption, and suboptimal service provision by service providers.
Innovation Solution
A system with a Coexistence Controller (CC) that modifies Wi-Fi access point parameters to prioritize Wi-Fi connectivity by scanning for competing LTE-U and LTE-LAA signals, adjusting parameters like signal strength and detection thresholds, and managing connections to optimize user preferences and service provider efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LTE connection mechanism is used, then connection reliability is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts connection parameters and switching thresholds based on real-time signal strength measurements and network conditions. The connection manager continuously monitors RSSI values and adapts the decision-making process for selecting between Wi-Fi and LTE connections, optimizing the balance between reliability and energy consumption according to current environmental conditions.
Solution Approach 2:
The patent modifies key parameters including RSSI thresholds for connection selection, transmission power levels, and handover criteria. By adjusting these parameters based on network conditions and user preferences, the system can shift between prioritizing connection reliability and conserving battery power, resolving the contradiction between these two objectives.
2Stability of the object's composition
If LTE connection is prioritized, then connection stability is improved, but service provider efficiency deteriorates
Solution Approach 1:
The connection manager implements dynamic connection management that adapts to both user needs and service provider objectives. By continuously monitoring network conditions, signal strength, and user behavior patterns, the system dynamically adjusts connection selection strategies to balance connection stability with service provider efficiency, allowing flexible optimization based on real-time conditions.
Solution Approach 2:
The system modifies connection parameters such as transmission power, frequency selection, and handover thresholds to optimize the balance between connection stability and service provider efficiency. By adjusting these parameters based on user preferences and network conditions, the system can prioritize Wi-Fi connections when appropriate, improving service provider efficiency while maintaining adequate connection stability.
3Adaptability or versatility
If Wi-Fi connection parameters are modified, then Wi-Fi connectivity availability is improved, but connection management complexity increases
Solution Approach 1:
The patent introduces a connection manager as an intermediary layer between the user equipment and the network. This intermediary component centralizes the complexity of managing multiple connection parameters and switching between different network types (Wi-Fi and LTE). By consolidating management functions in a dedicated module, the system improves Wi-Fi connectivity availability through parameter optimization while containing complexity within a manageable architectural component.

AI summary
Methods and apparatus for monitoring and controlling access to coexisting first and second networks within a venue. In one embodiment, the first network is a managed content delivery network that includes one or more wireless access points (APs) in data communication with a backend controller which communicates with a dedicated background scanner. The background scanner scans for coexisting networks within the venue, and reports this to the controller. In one variant, the controller dynamically adjusts transmit characteristics of the AP(s) to manage interference between the coexisting networks. In another variant, the controller causes the energy detect threshold of a client device to be lowered so that the device may detect WLAN signals in a scenario where a coexisting RAT (for example, LTE-U or LTE-LAA) occupies the same channel and/or frequency.
