Selective Multiuser Call Recording via Segmentation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems face challenges in efficiently recording multiuser calls due to the dramatic increase in data size as the number of users on a call increases, and there is a need to selectively disable recording for certain users.

Innovation Solution

The system allows for the selective recording of users in a multiuser call by enabling users to request recording and selectively disable recording for specific user devices through a user interface, ensuring that only desired users are recorded.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If recording is enabled for all users in a multiuser call, then complete call recording is achieved, but data size increases dramatically

Engineering Contradiction:

Improvecall recording completenessVSAvoiddata size

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent segments the multiuser call recording into individual user recordings. Each user's audio stream is recorded separately, allowing selective combination or exclusion of specific users' recordings. This segmentation enables the system to manage data size by only recording and storing portions of the total call data that are actually needed, rather than recording all users uniformly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by allowing different recording settings for different users within the same multiuser call. Each user can have individual recording permissions and settings, enabling the system to optimize data storage by recording high-quality audio for some users while reducing or eliminating recording for others based on specific needs and preferences.

Inventive Principle:

Principle #3Local quality

2Reliability

If recording is enabled for all users in a multiuser call, then complete call recording is achieved, but system complexity increases

Engineering Contradiction:

Improvecall recording completenessVSAvoidrecording management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by allowing users to independently control their own recording permissions and settings within the multiuser call. Each user can enable or disable their own recording through their device settings without requiring manual configuration by the system administrator or other users, thereby simplifying the overall system management complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent creates a universal recording management system that handles multiple users, multiple recording scenarios, and various permission configurations through a unified framework. This multi-functional approach consolidates what would otherwise require separate management mechanisms for each user and scenario, reducing overall system complexity while maintaining flexibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If selective recording is implemented, then user preferences are accommodated, but ease of operation decreases

Engineering Contradiction:

Improveuser preference accommodationVSAvoidrecording configuration ease

Core Design Contradiction:

AI summary

Disclosed are systems and techniques for multiuser communications. For instance, a process can include establishing a multiuser call, the multiuser call including at least two other network devices. The process can further include receiving a request to record the multiuser call, receiving an indication to disable recording for a second network device, and causing recording of data from the second network device on the multiuser call to be disabled.
