NFC Call Transfer via Intermediary Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice communication systems lack an efficient method to transfer calls between devices without disrupting the call connection, especially in scenarios where a user needs to hand over a call to another device without losing their place in a queue or requiring direct dialing and waiting.
Innovation Solution
A method and apparatus utilizing near field communications (NFC) to transfer voice calls between endpoint devices, allowing seamless handover of call connections by detecting a request via NFC and transferring the communication path from one device to another, ensuring secure and uninterrupted call continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user passes their mobile phone to another household member to speak with a family member, then the call can be transferred to another device, but the user's mobile phone is monopolized and the user cannot make other calls
Solution Approach 1:
The patent introduces a call transfer server as an intermediary that mediates between the first mobile phone and the second mobile phone. The server receives the call on the first phone, then transfers it to the second phone through NFC authentication, allowing the first phone to be released for other uses while maintaining call continuity
2Productivity
If a caller transfers their call to another device without NFC technology, then the call can be moved to a different device, but the process requires direct dialing and waiting in queues
Solution Approach 1:
The patent implements preliminary action by establishing NFC authentication and obtaining device information before the actual call transfer occurs. The server pre-loads necessary call data and authentication credentials, so when the transfer is initiated, it can execute immediately without requiring the receiving device to dial or wait in queues
Solution Approach 2:
The patent replaces the mechanical dialing process with NFC-based automatic connection. Instead of manually dialing the number and waiting for connection establishment, the NFC technology automatically authenticates and establishes the call transfer through wireless communication, eliminating the need for manual intervention and queue waiting
3Ease of operation
If call transfer information is exchanged between devices, then the transfer can be initiated, but personal information may be exposed during the exchange
Solution Approach 1:
The patent uses a call transfer server as a secure intermediary that handles all information exchange. The first mobile phone communicates with the server to initiate transfer, and the server securely transmits authentication codes and device information to the second phone through NFC, preventing direct exposure of personal information between devices
Solution Approach 2:
The patent uses authentication codes as secure copies that represent device identity without exposing actual personal information. Instead of sharing phone numbers or personal data, the system generates and exchanges temporary authentication credentials that enable call transfer while maintaining privacy

AI summary
An apparatus is disclosed. For example, the apparatus includes a first communication interface to establish a first communication path with a first endpoint device, a second communication interface to establish a second communication path with a second endpoint device, wherein the second endpoint device is to establish a voice call with the first endpoint device, a processor, and a non-transitory computer-readable medium storing a plurality of instructions. The instructions when executed by the processor cause the processor to detect a request to transfer the second communication path from the second endpoint device to a third endpoint device, wherein the request includes information obtained by the third endpoint device via near field communications (NFC) with the second endpoint device and transfer the second communication path from the second endpoint device to the third endpoint device to disconnect the second endpoint device.
