Presence Service Status Sharing From Active Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current presence services in communication networks only provide limited status information input by users and do not offer a seamless service based on the status information of called parties, lacking detailed status information and convenient sharing capabilities.
Innovation Solution
An apparatus and method that automatically extracts and updates presence information, including application and content indication information, to provide detailed status information and enable content sharing through a communication network, using a presence server to transmit and display this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the presence service provides only user-input status information, then the service is simple to implement, but the information detail and usefulness are limited
Solution Approach 1:
The system automatically extracts presence information from applications without requiring user input. The presence information extraction module autonomously monitors application states, extracts relevant information (location, activity, content), and updates the presence server, eliminating the need for manual user input while providing detailed status information.
Solution Approach 2:
The system pre-extracts and stores presence information from applications in advance of any service requests. By continuously monitoring application states and preparing presence information beforehand, the system ensures detailed information is readily available when needed, reducing information loss without increasing operational complexity.
2Adaptability or versatility
If the presence service provides detailed status information automatically, then the information usefulness improves, but the system complexity increases
Solution Approach 1:
The presence service system is divided into distinct functional modules: presence information extraction module, presence information transmission module, and presence information processing module. This segmentation allows each module to perform specific tasks independently, improving service versatility while managing system complexity through modular design.
Solution Approach 2:
The presence information extraction module serves multiple functions by extracting various types of information (location, activity status, content information) from different applications. This multi-functionality increases service adaptability without proportionally increasing system complexity, as a single module handles diverse extraction tasks.
3Reliability
If manual input of presence information is required, then the system is easier to control, but the information timeliness and accuracy decrease
Solution Approach 1:
The system automatically extracts presence information from application data structures without requiring user input. The extraction module directly accesses application information (location services, activity recognition, content metadata) and extracts accurate, timely presence data, improving both reliability and ease of operation by eliminating manual input requirements.
Solution Approach 2:
The system continuously monitors application states and automatically updates presence information based on real-time data changes. This feedback mechanism ensures information accuracy by constantly comparing current application states with stored presence information and updating accordingly, without requiring user intervention.
Data Source
AI summary
An apparatus is capable of sharing information through a presence service in a communication network and capable of providing presence information of a Mobile Station (MS). The apparatus extracts at least one of application information and contents indication information from an application in execution. Presence information is generated that includes at least one of the application information and the contents indication information, and transmitting the presence information to a presence server.
