Location-Based Call Failure Announcements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice call announcement systems do not provide specific reasons for call failures, leaving callers uninformed about the underlying events affecting their communication sessions, which can impact service quality or prevent call establishment.
Innovation Solution
A location-based announcement system that determines the caller's and receiver's locations to identify potential events impacting the communication session, such as weather events or network failures, and provides targeted announcements to inform users about the cause of call failures or service issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If generic announcements are provided to callers, then the system complexity is reduced, but the information quality and user awareness of call failure causes deteriorates
Solution Approach 1:
The system determines the caller's location in advance by receiving location information from the mobile device before processing the call failure announcement. This preliminary location determination enables the system to proactively identify relevant local events that may have caused the call failure, thereby providing more informative announcements without significantly increasing system complexity during the actual call handling process
Solution Approach 2:
The patent introduces an intermediary component that receives location information from the mobile device, queries event data associated with that location, and matches events to call failure reasons. This intermediary layer handles the complex task of location-event-correlation separately from the core call handling system, maintaining information quality while managing system complexity through modular architecture
2Reliability
If location-based event identification is implemented, then the user awareness of call failure causes is improved, but the information processing time and system complexity increases
Solution Approach 1:
The system performs location determination and event identification in advance, before the call failure announcement is delivered to the user. By pre-fetching location data and pre-identifying relevant events, the system minimizes the additional processing time required at the moment of call failure, while still providing accurate and reliable information about the cause of the failure
Solution Approach 2:
The system queries for events within a predefined geographic radius around the caller's location, rather than searching the entire database. This partial action approach focuses computational resources on the most relevant geographic area, reducing information processing time while maintaining high accuracy in identifying the actual cause of call failure
Data Source
AI summary
In an example, a request is received from a first user equipment (UE). The request corresponds to a request to establish a communication session with a second UE. A location of the first UE is determined based upon the request. An event datastore is analyzed, based upon the location of the first UE, to identify one or more events potentially impacting telecommunication services provided to the first UE. Based upon the one or more events, an announcement is provided for presentation on the first UE.
