LCIB Pilot-Beacon Power Adjustment for Unauthorized Station Exclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Macro-network base stations face challenges in efficiently managing access and resource allocation to mobile stations, particularly in providing differentiated service to authorized users while excluding unauthorized ones, especially in environments where coverage gaps exist and resource limitations are present.
Innovation Solution
Low-Cost Internet Base Stations (LCIBs) employ a ranging process to dynamically adjust pilot-beacon transmission power based on historical usage data, classifying mobile stations as authorized or unauthorized, and configuring coverage to prioritize authorized users, thereby managing access and resource allocation effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If macro-network base stations provide public access to all mobile stations, then coverage area and accessibility are improved, but network security and resource allocation efficiency deteriorate due to unauthorized access
Solution Approach 1:
The patent segments mobile stations into authorized and unauthorized groups based on their association with LCIBs. Macro base stations provide differentiated access: public access for unauthorized stations and restricted access for authorized stations. This segmentation resolves the contradiction by allowing broad accessibility while maintaining security through group-based access control.
Solution Approach 2:
The patent applies local quality by providing different service qualities to different mobile stations based on their authorization status. Authorized mobile stations receive prioritized service and resource allocation, while unauthorized stations receive standard service. This resolves the contradiction by tailoring accessibility and security measures to local conditions of each mobile station.
2Ease of operation
If LCIBs serve all mobile stations in coverage area, then ease of operation is improved, but resource allocation efficiency deteriorates due to lack of prioritization
Solution Approach 1:
The patent implements local quality by providing differentiated service quality to mobile stations based on their authorization status. Authorized mobile stations receive prioritized resource allocation and preferential treatment during resource contention, while unauthorized stations receive standard service. This resolves the contradiction by maintaining ease of operation for all users while improving resource allocation efficiency through localized prioritization.
Solution Approach 2:
The patent employs feedback mechanisms where LCIBs monitor mobile station usage patterns and authorization status, and macro base stations adjust resource allocation based on this feedback. Authorized stations identified through LCIB association receive preferential resource allocation, resolving the contradiction by using feedback to balance service availability and resource efficiency.
3Ease of operation
If macro base stations allocate resources equally to all mobile stations, then fairness is improved, but network performance deteriorates due to inability to prioritize authorized users
Solution Approach 1:
The patent applies local quality by implementing differentiated resource allocation based on mobile station authorization status. Authorized mobile stations receive preferential resource allocation and prioritized service, while unauthorized stations receive standard allocation. This resolves the contradiction by maintaining fairness for unauthorized users while improving overall network performance through prioritization of authorized users.
Solution Approach 2:
The patent changes the allocation parameter from equal treatment to differentiated treatment based on authorization status. Macro base stations adjust resource allocation parameters dynamically, providing enhanced resources to authorized mobile stations and standard resources to unauthorized ones. This resolves the contradiction by using parameter changes to balance fairness and performance.
4Area of stationary object
If LCIBs transmit pilot beacons at high power, then coverage area is improved, but energy consumption and interference increase
Solution Approach 1:
The patent implements dynamics by making pilot beacon transmission power adjustable rather than fixed. LCIBs can dynamically adjust transmission power based on the number and location of associated mobile stations, providing high power when needed for coverage and low power when not needed to conserve energy. This resolves the contradiction by using dynamic adjustment to balance coverage area and energy consumption.
Solution Approach 2:
The patent changes the transmission power parameter dynamically based on operational conditions. LCIBs adjust pilot beacon power levels according to the number of authorized mobile stations and coverage requirements, reducing power consumption when full coverage is not needed while maintaining adequate coverage when required. This resolves the contradiction through parameter changes that adapt to actual operational needs.

AI summary
Methods and systems are provided for implementing a low-cost-Internet-base-station-(LCIB) user-adaptation algorithm. In an embodiment, an LCIB receives usage attempts from a plurality of mobile stations. The LCIB stores records corresponding to the usage attempts, where each record identifies the corresponding mobile station from which the corresponding usage attempt was received. The LCIB uses the records to classify each mobile station in the plurality of mobile stations as authorized or rather as unauthorized. The LCIB then configures its coverage area so as to exclude the unauthorized mobile stations.
