Preferred User Zone Lists for Private Access Point Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems lack efficient mechanisms for access terminals to identify and switch to preferred private access points based on geographic location, leading to unnecessary energy consumption and potential misconnection with unauthorized access points.
Innovation Solution
Implementing a system where access terminals receive geographic location information, such as GPS coordinates, to configure preferred user zone lists, allowing them to efficiently connect to authorized private access points by comparing their location to the access points' coordinates, thereby reducing battery consumption and ensuring secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access terminals use conventional neighbor list information to select access points, then they can maintain basic connectivity, but they consume unnecessary energy and may connect to unauthorized access points
Solution Approach 1:
The system pre-configures preferred user zone lists with geographic location information and authorized access point identifiers before the access terminal needs to connect. This allows the terminal to quickly determine authorized access points based on its current location without performing energy-intensive searches or evaluations of unauthorized access points.
Solution Approach 2:
The patent implements location-specific configuration by associating different preferred user zone lists with different geographic locations. The access terminal receives and applies the appropriate configuration based on its current geographic position, ensuring it only considers authorized access points relevant to its location, thereby reducing energy consumption and improving connection security.
2Productivity
If access terminals continuously search for available access points without location awareness, then they can find any accessible network, but they waste time and energy on unauthorized or distant access points
Solution Approach 1:
The system pre-configures preferred user zone lists with geographic location information and authorized access point identifiers before the access terminal needs to connect. This allows the terminal to quickly determine authorized access points based on its current location without performing energy-intensive searches or evaluations of unauthorized access points.
Solution Approach 2:
The patent changes the search parameters by incorporating geographic location information into the access point selection process. Instead of searching all available access points, the terminal uses its determined location (via GPS or other means) to filter and identify only those access points within its preferred user zone, dramatically reducing search time and improving connection speed.
3Ease of manufacture
If private access points are deployed without centralized configuration management, then deployment is simple, but coordination and authorization between multiple access points becomes problematic
Solution Approach 1:
The patent introduces a configuration server as an intermediary between private access points and access terminals. The server centrally manages the creation, storage, and distribution of preferred user zone lists, handling the complex task of coordinating authorization information across multiple access points. This allows individual access points to remain simple while the system as a whole achieves sophisticated coordination through the mediating server.
Data Source
AI summary
Information is received identifying a geographic location of an access point in a radio access network. Access information is assigned and communicated to the access point, and the access information and the geographic location information is communicated to an access terminal. The access terminal identifies the access point as a preferred access point, including its geographic location. The access terminal receives information identifying its own geographic location, and when the access terminal is near the access point, the access point is used to access the network. The access point receives information identifying its geographic location and communicates the geographic location information to a configuration server. The access point receives access information from the configuration server and provides access terminals access to the network using the access information.
