Geofenced Wireless Access Control for Private Team Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in sports venues like baseball parks, ensuring private communication between specific location areas such as dugouts and bullpens is challenging due to the risk of interception by other teams or third parties, and spectrum congestion can impair communication reliability.
Innovation Solution
Implementing a closed communication system using cellular base stations, proximity beacons, and geofencing technology to restrict wireless access to specific pre-defined location areas, ensuring that only devices within the designated area can communicate and receive calls, while preventing outside interference and congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless access is opened to public networks, then communication coverage and accessibility are improved, but communication privacy and security deteriorate due to interception risks
Solution Approach 1:
The patent segments the wireless communication network into isolated closed networks for different location areas (e.g., dugout, bullpen). Each location area has its own restricted wireless network that does not interconnect with others, preventing cross-location interception while maintaining communication accessibility within each area.
Solution Approach 2:
The patent introduces location verification mechanisms and network access control intermediaries that mediate between devices and the wireless network. These intermediaries verify device location and authorization before allowing network access, enabling public accessibility while preventing unauthorized interception through controlled access points.
2Area of stationary object
If wireless spectrum is shared with other devices, then network coverage is improved, but communication reliability deteriorates due to spectrum congestion
Solution Approach 1:
The patent divides the wireless spectrum into separate dedicated channels for each closed location area. Each location area operates on its own frequency spectrum without sharing with other areas, eliminating congestion from external devices while maintaining adequate coverage within the restricted area through localized base stations.
3Object-affected harmful factors
If closed network restriction is implemented, then communication privacy is improved, but device mobility and ease of operation deteriorate due to location constraints
Solution Approach 1:
The patent implements dynamic location verification that automatically updates device authorization based on real-time location data. Devices can move freely within their designated location area boundaries without manual reconfiguration, as the system dynamically adjusts network access permissions based on geographic position, maintaining both privacy and mobility.
Solution Approach 2:
The patent enables devices to automatically perform location verification and network registration without user intervention. The system self-manages authorization by monitoring device position and automatically granting or revoking network access based on whether the device is within authorized boundaries, eliminating manual setup while maintaining location-based privacy.

AI summary
A system is described herein that includes mobile communication devices and a cellular base station to communicate with a telecommunication network. The mobile communication devices access telephony service through the cellular base station when inside a geofence. The mobile communication devices determine whether they are inside the geofence based on distances from proximity beacons. When outside of the geofence, the mobile communication devices are prevented from accessing telephony service through the cellular base station. When inside the geofence, the mobile communication devices may access telephony service through the cellular base station. The mobile communication devices may only make and receive calls from mobile communication devices of a specific other system. When a call is received at the system, the mobile communication devices of the system are rung. To enable this, a serving call session control function of the telecommunication network forks a call directed to the system.
