Presence Service Access Device for Non-Person Entity Data Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current presence service systems face challenges in efficiently managing and processing presence information from non-natural person entities, such as radio stations and transportation services, due to differences in information formats, high service traffic loads, and difficulties in accessing and controlling these services uniformly and securely.
Innovation Solution
A presence service access device is introduced, which includes modules for identity authentication, service scheduling, and protocol conversion to manage and forward presence information from non-natural person entities to corresponding presence servers, reducing server load and enhancing security through separate access and control mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If presence information from non-natural person entities is directly forwarded to presence servers, then service coverage is expanded, but server load becomes extremely large
Solution Approach 1:
The patent introduces a presence service access device as an intermediary component between non-natural person entities and presence servers. This access device collects presence information from various non-natural person entities (radio stations, transportation services, etc.) and forwards it to appropriate presence servers, thereby expanding service coverage while preventing direct connection overloads on servers.
2Productivity
If presence servers directly connect with non-natural person entities, then information distribution is enabled, but access control and security become difficult
Solution Approach 1:
The presence service access device serves as a security intermediary that implements authentication and authorization mechanisms. It verifies the identity of non-natural person entities before allowing them to publish presence information, and controls which presence servers can access the information, thereby enhancing security and access control while maintaining information distribution capabilities.
Solution Approach 2:
The patent segments the presence service architecture into distinct functional components: presence information collection (access device), presence information storage (presence server), and presence information distribution (watcher client). This segmentation isolates security control functions in the access device from the information distribution functions in the presence server, making both security and productivity achievable simultaneously.
3Device complexity
If presence information formats from different non-natural person entities are processed uniformly, then system complexity is reduced, but information conformity becomes difficult to ensure
Solution Approach 1:
The patent employs parameter transformation and normalization techniques where the access device converts presence information from various formats (different non-natural person entities) into a unified standard format before forwarding to presence servers. This maintains low system complexity by using a single processing pipeline while ensuring information conformity through standardized parameter transformation.

AI summary
A presence service access device is disclosed for a presentity to publish presence information and transmit said information to the presence server, the device comprising a presentity communication module and a service scheduling control module. Further disclosed is a presence service system using the presence service access device, comprising a presentity, a presence service access device, a presence server, and a watcher client. Also disclosed is a method of publishing and acquiring presence information comprising steps of: 1. a presentity which publishes presence information; 2. the presence service access device which receives the presence information published by the presentity and forwards the same to a presence server; and 3. the presence server which distributes the presence information to corresponding watcher client. According to the present invention, various presentities provide presence information to watcher clients by connecting presence servers through a presence service access device.
