Presence Signaling Subscription Synchronization in Communication Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing presence signaling management in communication networks does not effectively prevent conflicts between presence signaling zones, particularly when presence signaling is activated for specific time slots, leading to potential errors in billing and location monitoring.
Innovation Solution
A method that verifies the support for presence signaling by the control entity and sends an indicator to the credit management entity to inhibit unnecessary subscriptions, ensuring that the control entity's subscription to the presence signaling mechanism is synchronized with the credit management entity's, thereby avoiding conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the credit management entity independently activates presence signaling for billing purposes, then billing accuracy is improved, but presence signaling zone conflicts occur when the control entity also activates signaling for the same zone
Solution Approach 1:
The control entity sends an indicator of support for the presence signaling mechanism to the credit management entity before the credit management entity activates presence signaling. This preliminary action allows the credit management entity to know whether the control entity will also be activating signaling, enabling it to adjust its behavior and avoid conflicts while maintaining billing accuracy.
Solution Approach 2:
The control entity provides feedback to the credit management entity about its support for and activation of presence signaling through the indicator. This feedback mechanism allows the credit management entity to make informed decisions about whether to activate presence signaling independently, preventing zone conflicts while ensuring accurate billing.
2Adaptability or versatility
If presence signaling is activated for specific time slots by the control entity, then network resource control is improved, but conflicts arise when the credit management entity simultaneously activates signaling for different zones
Solution Approach 1:
The control entity sends the indicator of support for presence signaling to the credit management entity in advance, before time slot-based activation occurs. This allows the credit management entity to coordinate its presence signaling activation with the control entity's time slot-based resource control, preventing conflicts while maintaining adaptability.
Solution Approach 2:
The system dynamically adjusts presence signaling activation based on the indicator from the control entity. The credit management entity can dynamically decide whether to activate presence signaling for specific time slots and zones based on the control entity's support indication, enabling flexible resource control without conflicts.
3Measurement precision
If the credit management entity subscribes to presence signaling without knowing about control entity's support, then billing monitoring is improved, but unnecessary subscriptions are created causing system complexity
Solution Approach 1:
The control entity provides feedback to the credit management entity about its support for presence signaling through the indicator. This feedback enables the credit management entity to make intelligent decisions about subscriptions, reducing unnecessary subscriptions and simplifying subscription management while maintaining accurate billing monitoring.
Solution Approach 2:
The credit management entity uses the indicator from the control entity to autonomously determine whether to activate presence signaling and create subscriptions. This self-service approach reduces unnecessary subscriptions and simplifies system complexity while ensuring accurate billing monitoring where needed.
