Merging CS and PS Calls in User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication systems do not support the merging of calls from different circuit switched (CS) and packet switched (PS) domains, limiting the ability to combine multiple calls into a conference call if they originate from different communication technologies.
Innovation Solution
A method and apparatus for user equipment (UE) to handle calls by merging or swapping calls between CS and PS domains, allowing for the integration of calls from different communication domains into a single conference call, using a mixing module to combine and manage voice data streams from various sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If calls from different CS and PS domains are merged, then communication versatility and user experience are improved, but system complexity and call management difficulty increase
Solution Approach 1:
The patent introduces a call management module that acts as an intermediary between the CS call module and PS call module. This mediator coordinates call merging operations, manages domain switching, and handles the complexity of inter-domain call coordination, thereby enabling versatile communication without proportionally increasing overall system complexity.
Solution Approach 2:
The call management module is designed with multi-functional capabilities to handle both CS and PS domain calls uniformly. It can manage calls from either domain independently or in combination, providing universal call management functionality that adapts to different call types and domains without requiring separate specialized management systems for each domain.
2Adaptability or versatility
If a mixing module is introduced to combine voice data streams, then call merging capability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a mixing module that combines voice data streams from both CS and PS domains into a unified audio output. This merging of data streams enables conference calls and seamless transitions between domains by consolidating multiple call sources into a single manageable interface, improving call merging capability while managing complexity through integration.
