Presence Management System with Preferred Service Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Converged communication networks face capacity issues due to simultaneous use of multiple services like VoP and instant messaging, leading to service degradation and increased network load from indiscriminate third-party interactions, which strain network resources.
Innovation Solution
A presence management system determines a preferred service for users based on service requirements and network capabilities, limiting network access and notifying third parties through presence features, thereby optimizing bandwidth usage and reducing indiscriminate service usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If presence features allow third parties to contact users when availability is indicated, then user accessibility and communication efficiency are improved, but network load and resource strain increase
Solution Approach 1:
The patent introduces an access control system as an intermediary between presence information and third-party communication attempts. This mediator receives presence updates, determines preferred services based on service requirements and network capabilities, and selectively allows or blocks third-party contact attempts. The intermediary filters indiscriminate contact while maintaining efficient communication channels, thus improving communication efficiency without proportionally increasing network load.
2Adaptability or versatility
If multiple communication services are simultaneously supported, then service versatility and user convenience are improved, but network capacity is exceeded and service quality degrades
Solution Approach 1:
The patent implements dynamic service selection where the access control system continuously monitors service requirements and network capabilities, adjusting preferred service determination in real-time. When network capacity is sufficient, multiple services are supported; when capacity degrades, the system dynamically shifts to preferred services that consume fewer resources. This dynamic adaptation maintains service versatility while preventing network overload and preserving service quality.
Solution Approach 2:
The system changes operational parameters by adjusting service selection based on network conditions. The access control system modifies which services are accessible by changing the preferred service determination criteria according to current network capacity, service requirements, and user presence status. This parameter adjustment allows the network to support versatile services when possible while maintaining reliability when resources are constrained.
3Speed
If indiscriminate third-party contact is permitted based on presence availability, then immediate communication is enabled, but bandwidth utilization increases and network performance suffers
Solution Approach 1:
The patent applies partial action by allowing only certain third-party contact attempts based on preferred service determination rather than permitting all contact attempts. The access control system selectively permits communication on preferred services while blocking others, achieving immediate communication on optimal channels without the excessive bandwidth consumption of indiscriminate contact across all available services.

AI summary
A presence management system comprising a communication system configured to transmit a first update message indicating a first presence status of a user for a first service, and transmit a second update message indicating a second presence status of the user for a second service, and an access control system configured to receive the first and second update message, process the first and second update messages to determine a preferred service for the user of the first and second services, and transmit a third update message to a presence system indicating the user and the preferred service for the user wherein the presence system updates a presence indicator for the user to indicate the preferred service.
