Enriched Calling Subject Line Parsing for IMS Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IP Multimedia Subsystems (IMS), determining enriched calling capabilities of devices and efficiently routing calls to specific sub-entities within entities with multiple sub-entities is challenging, leading to poor user experience and increased resource utilization due to the need for users to navigate through Speech Interactive Voice Response (SIVR) or Automated Attendant (AA) systems.
Innovation Solution
The system implements a presence server that stores device capabilities and uses enriched calling capabilities to parse subject lines from user inputs, routing calls directly to relevant sub-entities by matching keywords with associated sub-entities, thereby bypassing SIVR or AA interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users navigate through SIVR or AA systems to reach sub-entities, then call routing is achieved, but user experience deteriorates and call duration increases
Solution Approach 1:
The system performs preliminary actions by detecting enriched calling capabilities before the call is established, parsing the subject line in advance, and determining the target sub-entity beforehand. This allows the call to be routed directly without requiring users to navigate through SIVR or AA systems during the call, thereby improving user experience and reducing call duration
Solution Approach 2:
The invention extracts the subject line from the call request and uses it to directly identify the target sub-entity, bypassing the traditional SIVR or AA navigation system. This extraction approach eliminates unnecessary interaction steps and directly connects users to the intended destination
2Productivity
If traditional call routing through SIVR/AA is used, then calls are connected, but resource utilization increases
Solution Approach 1:
The system extracts and utilizes the subject line information from call requests to directly determine routing destinations, eliminating the need for complex SIVR/AA system processing. This reduces computational resources and system load while improving call management efficiency
Solution Approach 2:
The system performs capability detection, subject line parsing, and routing determination in advance before call establishment, reducing real-time processing requirements and resource consumption during active calls
3Ease of operation
If enriched calling capabilities are implemented, then direct routing to sub-entities is achieved, but system complexity increases
Solution Approach 1:
The system implements a universal capability detection mechanism that works across different UE types and network configurations. The presence server and TAS work together in a standardized manner to detect enriched calling capabilities, parse subject lines, and determine routing, providing a multi-functional solution that handles various call scenarios without requiring separate complex systems for each case

AI summary
Systems, methods and apparatuses for implementing enriched calling services for devices may include a first User Equipment (UE) that sends a call request to an IP Multimedia Subsystem (IMS) Core network and a presence server. The IMS core network may determine that the first UE supports enriched calling services and may enable the first UE to perform an enriched calling operation. The IMS core network may forward the call request to a terminating device, such as a second UE and/or a computing device, with the enriched calling operation.
