Server Event Data Analysis for Call State Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication networks lack the ability to distinguish between actively rejected and unanswered connection attempts, making it difficult to provide effective value-added services that inform subscribers about connection attempts without generating unnecessary signaling.
Innovation Solution
A method and system where a connection control unit generates and transmits event data to a server, which determines the state of a callee's connection attempt, differentiating between active rejections and network timeouts by analyzing event data, and decides whether to notify the subscriber about missed calls based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the service monitors and notifies all connection attempts to the subscriber, then the subscriber receives complete information about connection attempts, but the subscriber becomes irritated due to unnecessary signaling
Solution Approach 1:
The patent applies local quality by differentiating the notification treatment based on the type of connection attempt. Instead of uniform notification for all connection attempts, the system selectively notifies only for specific types (e.g., actively rejected calls) while suppressing notifications for others (e.g., network timeouts), thereby tailoring the information delivery to the local characteristics of each event type.
Solution Approach 2:
The patent inverts the conventional approach by not notifying the subscriber about all connection attempts, but rather by identifying and notifying only about specific meaningful events. Instead of a default-notify-all approach, the system uses a default-suppress-with-exceptions approach, where notifications are suppressed unless the connection attempt matches specific criteria indicating subscriber relevance.
2Reliability
If the network provides detailed information about connection attempt reasons, then the service quality improves, but the device complexity increases
Solution Approach 1:
The patent extracts only the essential and meaningful information from connection attempt events that are relevant for subscriber notification. Instead of processing and transmitting all available connection attempt data, the system extracts and focuses on specific event types (such as active rejections) that have high subscriber relevance, thereby reducing the complexity of information processing while maintaining service quality.
Solution Approach 2:
The patent segments connection attempt events into distinct categories based on their nature and subscriber relevance. By dividing connection attempts into different event types (e.g., actively rejected, network timeout, unanswered), the system can apply different processing and notification rules to each segment, simplifying the overall service logic while providing differentiated information quality.

AI summary
The present invention relates to a method for generating information relating to a subscriber B (120) with respect to a call connection attempt from a subscriber A (110) to the subscriber B (120) by a server (140). The method comprises: receiving event data (210); determining (220) if the event data comprises an event representing a busy state; and it that case determining (230) if the previous event represents a call ringing state; and in that case generating an indication that the call connection attempt is rejected (240) by the subscriber B (120); and in response to a determination that the previous event does not represent the call ringing state generating an indication that the call connection attempt did not reach (250) the subscriber B (120). The invention also relates to a server, a system and a computer program product.
