Zone Presence Management via Subscription Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Zonal Presence APIs only provide basic event sensing for user entry, exit, and transfer within a zone, lacking detailed information on user terminal access and events in wireless access points, which limits their functionality for application servers.
Innovation Solution
An apparatus and method for managing zone presence that includes a presence managing unit to process subscription requests from application servers, determining if user terminal access information matches the request, and providing detailed access and event information through a RESTful API, utilizing a zone presence information database to record and manage interested area, user, and event information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the Zonal Presence API provides only basic event sensing functions, then the system complexity is low, but the information detail and functionality are insufficient
Solution Approach 1:
The patent segments the zone presence management system into distinct functional modules: a presence managing unit for receiving subscription requests and determining user terminal access information, an API processing unit for providing presence information through RESTful APIs, and a database unit for storing zone configuration and subscription data. This segmentation allows the system to provide detailed information while maintaining manageable complexity through modular architecture.
2Adaptability or versatility
If the system provides detailed access information and event information, then the functionality is enhanced, but the processing complexity increases
Solution Approach 1:
The patent implements a universal presence managing unit that handles multiple types of subscription requests through a single interface. This unit can process requests for user terminal access information, event information, and various zone presence data using the same determination logic and database query mechanisms, thereby providing enhanced functionality without proportionally increasing processing complexity.
Solution Approach 2:
The patent introduces an API processing unit as an intermediary layer between the presence managing unit and application servers. This unit standardizes communication through RESTful APIs, mediating the complex internal processing with simple, uniform external interfaces, thus enhancing functionality while shielding application servers from processing complexity.
3Loss of information
If the system manages multiple wireless access points and user terminals, then the information completeness improves, but the data management complexity increases
Solution Approach 1:
The patent segments data management into specialized database tables: zone configuration information tables for wireless access point data, user subscription information tables for terminal access data, and event information tables for occurrence data. This segmentation enables complete information management across multiple access points and terminals while reducing data management complexity through organized, purpose-specific data structures.

AI summary
Provided is an apparatus for managing zone presence, which manages presence information of a zone including a plurality of wireless access points, including: a presence managing unit receiving a subscription request from an application server and determining whether user terminal access information received from at least any one among the plurality of wireless access points corresponds to the subscription request; and an API processing unit providing the presence information to the application server when the user terminal access information corresponds to the subscription request.
