IMS Branded Calling Across Networks to Avoid Spam Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for branding voice calls in telecommunications systems, such as STIR/SHAKEN, often incorrectly mark enterprise calls as spam, leading to blocked calls and limited flexibility in network services, especially when devices are on different carrier networks.
Innovation Solution
A telecommunications system with a Telephony Application Server (TAS) in the IP Multimedia Subsystem (IMS) detects branding service subscriptions, allowing for the presentation of branding information, including a preferred number, name, and logo, on both in-network and off-network devices, using certificate management platforms for authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If STIR/SHAKEN branding is used for voice calls, then call authentication is improved, but enterprise calls are incorrectly marked as spam and blocked
Solution Approach 1:
The patent changes the branding information parameters by allowing customizable fields (preferred number, name, logo, reason for calling) that can be dynamically selected and presented. This enables enterprise calls to present appropriate branding information that distinguishes them from spam, while still maintaining authentication through the IMS originated calling framework.
Solution Approach 2:
The system dynamically selects and presents branding information based on the call context, subscriber profile, and network conditions. The TAS retrieves and presents appropriate branding information from subscriber profiles, allowing the branding presentation to adapt to different call scenarios rather than using static authentication markers.
2Stability of the object's composition
If traditional branding solutions are used, then brand identity is preserved, but flexibility in network services is limited especially across different carrier networks
Solution Approach 1:
The patent implements a universal branding solution through the IMS originated calling framework that works across different carrier networks. The TAS can present branding information for both in-network and off-network devices, and the system supports multiple branding information types (number, name, logo, reason) that can be used in various network scenarios, providing both consistency and flexibility.
Solution Approach 2:
The Telephony Application Server (TAS) acts as an intermediary that mediates between the originating and terminating devices, managing the presentation of branding information. The TAS retrieves branding information from subscriber profiles and presents it appropriately, facilitating cross-network communication while maintaining brand identity without requiring direct integration between different carrier networks.
3Productivity
If branding information is presented on all devices, then call acceptance rates are improved, but device complexity and authorization management increase
Solution Approach 1:
The system implements self-service through pre-authorization mechanisms where devices are pre-configured with branding information from subscriber profiles before calls are made. The TAS automatically retrieves and presents the appropriate branding information without requiring real-time authorization requests, reducing complexity while maintaining call acceptance improvements.
Solution Approach 2:
Branding information is prepared and stored in subscriber profiles in advance, and devices are pre-authorized to present this information. The TAS has the branding information ready before the call is established, eliminating the need for complex real-time authorization management during the call setup process.

AI summary
The disclosed technology relates to branding a voice call. A telecommunications system including a telephony application server (TAS) of an IP Multimedia Subsystem (IMS) can receive an indication of a voice call initiated at an originating endpoint device for a terminating endpoint device. The system detects that the originating endpoint device has a branding service subscription and identifies a profile for the subscription stored at a profile application server. The profile can include branding information for the originating endpoint device. The system can cause the terminating endpoint device to present the branding information upon receipt of the voice call.
