Server-Mediated Device Switching for Seamless Call Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices cannot seamlessly switch between different communication devices during active conversations or data transactions without interrupting or dropping the connection, which is inconvenient and can be disruptive, especially in critical situations like emergency calls or when switching between poor signal areas.
Innovation Solution
A telecommunications system and method that involves a server configured to manage calls between multiple devices, allowing for seamless switching by conferencing calls between devices, authenticating users, and maintaining control over inbound, outgoing, and in-progress communications, enabling smooth transitions without interrupting ongoing conversations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user switches devices during an active conversation using traditional methods, then the user can change devices, but the conversation is interrupted or dropped and the other party becomes aware of the switch
Solution Approach 1:
The server acts as an intermediary that receives the first call from the first device, answers it, then receives a second call from the second device, answers it, and conferences both calls together. This intermediary approach allows seamless device switching while maintaining call continuity and preventing the other party from noticing the switch.
Solution Approach 2:
The call switching process is segmented into distinct phases: initial call setup, device switch request, new call establishment, and call conferencing. This segmentation allows the system to manage the complex switching operation in manageable steps while maintaining uninterrupted communication.
2Ease of operation
If a mobile device is used during a conversation, then the user has mobility, but the battery may deplete causing the device to power-down during the conversation
Solution Approach 1:
The system allows the user to pre-register multiple devices with the server before needing to switch. When a device switch is needed, the user simply requests the switch and the server has the second device ready to receive and conference the call, enabling seamless transition without interruption.
Solution Approach 2:
The server mediates the battery depletion issue by maintaining the call connection while the user switches from a mobile device to a landline or other device. The server holds the call and conferences it to the new device, ensuring continuous communication regardless of the original device's power status.
3Adaptability or versatility
If a user enters an area with poor wireless signal, then the user remains in location, but the quality of service drops requiring a device switch
Solution Approach 1:
The system dynamically adapts to changing signal conditions by allowing real-time device switching. When signal quality deteriorates, the user can switch to a device with better reception (such as a landline), and the server maintains the call connection throughout the transition.
Solution Approach 2:
The system changes the communication parameter from wireless mobile to wired landline or alternative wireless carrier by switching devices. This parameter change allows the user to maintain call quality despite poor signal conditions in the original location.
4Reliability
If a landline telephone is used during a conversation, then the user has stable connection, but the user cannot leave the location without interrupting the call
Solution Approach 1:
The user pre-registers their mobile device with the server along with their landline device. When needing to leave the location, the user requests a device switch and the server has the mobile device ready to receive the conferenced call, enabling location flexibility while maintaining connection stability.
Solution Approach 2:
The server acts as an intermediary that receives the call at the landline, then conferences it to the mobile device when the user requests to leave. This intermediary approach allows the user to maintain a stable connection through the landline while gaining location flexibility through the mobile device.
