Priority Calling Using Cloud-Based Signaling for VoLTE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices cannot prioritize call connection requests or messages effectively, as all incoming alerts are treated equally, and users cannot configure priority notifications, leading to missed important calls or messages when in silent or do not disturb mode.
Innovation Solution
Implementing a mechanism to include priority level indications in call connection requests and messages, allowing users to configure specific ringtone and vibration patterns for prioritized contacts, which can override silent or do not disturb mode settings, using Session Initiation Protocol (SIP) extensions or separate data connections to ensure timely notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all incoming call connection requests and messages are treated with equal priority, then the system maintains simplicity in alert handling, but important calls or messages cannot be distinguished from regular ones, leading to potential missed notifications when silent or do not disturb mode is active
Solution Approach 1:
The patent introduces priority level parameters (e.g., high, medium, low priority) that can be assigned to different contacts. The receiving device evaluates these priority parameters to determine whether to override silent or do not disturb mode settings, thereby improving notification reliability without requiring fundamental system restructuring
Solution Approach 2:
The contact list is segmented into different priority groups, and alert handling is segmented into different pathways based on priority level. High-priority contacts trigger one set of actions (potentially overriding silent mode) while regular contacts trigger another set, allowing differentiated treatment without complete system redesign
2Ease of operation
If users configure custom ring tones and vibration alerts for different contacts, then personalized notification preferences can be achieved, but the receiving user cannot receive prioritized notifications in timely manner when silent or do not disturb mode is active
Solution Approach 1:
The silent or do not disturb mode settings are made dynamic rather than static. The system continuously evaluates incoming call priority levels against the current mode state, and automatically adjusts the effective state (allowing or blocking notifications) based on the priority evaluation, ensuring timely delivery of important notifications while maintaining user-defined preferences
3Reliability
If limited alerts from authorized governmental agencies are able to bypass user settings, then critical emergency notifications can be delivered, but known contacts such as family members or doctors cannot prioritize their call connection requests or messages
Solution Approach 1:
The priority indication mechanism is designed to be universal, serving both governmental emergency notifications and personal contacts (family, doctors, etc.). The same priority evaluation framework and override logic applies to all incoming calls and messages regardless of source, making the system versatile while maintaining reliable critical notification delivery

AI summary
This Application describes mechanisms to provide priority levels for call connection requests and/or messages from a sending device to a receiving device. The receiving device is configured to allow prioritized notification alerts for incoming call connection requests and/or for incoming messages from a sending device to override a silent or do not disturb mode for one or more contacts based on i) a priority level provided with the call connection request or message and ii) a priority setting for the sending device or a set of devices associated with a user of the sending device.
