Call Application Server for Seamless Mobile Soft Terminal Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems fail to provide seamless call switching between a soft terminal (such as a PC client) and a mobile terminal that share the same number, preventing users from maintaining calls across different devices without interruption.
Innovation Solution
A method and system for call switching based on a mobile terminal and a soft terminal of the same number, utilizing a call application server that receives switching instructions, parses command tabs, and performs seamless switching between the two devices over IP and GSM/3G networks, allowing users to switch ongoing calls between the soft terminal and mobile terminal without disrupting the call for the opposite party.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a soft terminal and mobile terminal use the same number simultaneously, then the user can access calls from multiple devices, but the system cannot switch ongoing calls between devices seamlessly
Solution Approach 1:
The patent introduces a call application server as an intermediary between the soft terminal and mobile terminal. The server receives switching instructions from either device, parses the command tabs to determine the switching type (call forwarding or call switching-into), and coordinates the handover of ongoing calls between the two terminals sharing the same number, enabling seamless call transfer without involving the called party
2Adaptability or versatility
If call switching between soft terminal and mobile terminal is implemented, then user mobility and flexibility improve, but system complexity increases due to additional switching mechanisms
Solution Approach 1:
The call application server performs multiple functions: it handles both call forwarding requests and call switching-into requests, manages switching instructions from either soft terminal or mobile terminal, and coordinates call handovers between different network types (IP network and GSM/3G network). This multi-functionality consolidates complex switching logic into a single universal component rather than requiring separate mechanisms for each switching scenario

AI summary
A method for switching call between a mobile terminal with the same number and a soft terminal includes: receiving the switching instruction information sent by the soft terminal user during the call between the soft terminal or the mobile terminal with the same number and the opposing user; confirming the type of the switching instruction information, and carrying out the switching performance between the mobile terminal with the same number and the soft terminal according to the type of the switching instruction information. A system and an equipment for switching call between a mobile terminal with the same number and a PC client are disclosed in the present invention.
