Event-Driven Presence Subscription via Communications Manager
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current presence-based interactive communication systems lack automatic mechanisms for subscribing and unsubscribing to presence services, leading to unnecessary network resource wastage and unpredictability in accessing future presence information, which limits the scope of available services and increases network traffic and costs.
Innovation Solution
A communications manager that detects events associated with presentities or watchers, automatically modifying the status of presence subscriptions based on predefined watcher preferences, allowing for event-driven subscription and unsubscription to presence services, thereby reducing network traffic and costs while increasing the scope of presence-enabled applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a watcher remains subscribed to the presence service indefinitely to ensure future presence information is available, then the availability of presence information is improved, but network traffic and resource consumption increase
Solution Approach 1:
The system performs preliminary actions by having watchers pre-define subscription criteria and conditions before events occur. The communications manager stores these preferences in advance and automatically executes subscription actions when specified conditions are met, eliminating the need for continuous subscription while ensuring timely information availability.
Solution Approach 2:
The communications manager automatically manages presence subscriptions based on pre-configured rules and detected events, without requiring continuous user intervention or manual subscription management. The system serves itself by autonomously subscribing or unsubscribing watchers based on objective conditions, reducing both network traffic and user burden.
2Adaptability or versatility
If a watcher manually subscribes to presence services at future points in time, then the scope of presence-enabled services is improved, but user operation complexity increases
Solution Approach 1:
The system enables self-service by allowing watchers to pre-configure subscription preferences and conditions. The communications manager then automatically executes subscription actions based on detected events without requiring users to manually subscribe at the right moments, greatly simplifying operation while maintaining service versatility.
Solution Approach 2:
Users perform preliminary configuration of subscription preferences and conditions in advance. This preliminary action captures the complexity upfront, allowing the system to automatically handle future subscription decisions based on simple condition matching, thereby expanding service scope while keeping user operations simple.
3Loss of energy
If automatic event-driven subscription mechanisms are implemented, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The communications manager serves as an intermediary between event sources and presence subscription management. It detects events, evaluates conditions, and executes subscription actions, thereby automating the process while containing system complexity within a dedicated management component rather than distributing it throughout the entire presence system.
Data Source
AI summary
Automatic subscription to presence services is achieved using a communications manager within a presence system. The communications manager is capable of detecting the occurrence of an event associated with at least one of a presentity and a watcher. The communications manager automatically subscribes or unsubscribes the watcher to receive presence information of the presentity in response to detection of the event.
