Call Forwarding Across Multiple Terminals Using Single Phone Number
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users carrying multiple devices with cellular communication chips face the inconvenience of needing separate phone numbers for each device, and existing call forwarding services do not effectively enable voice call communication between terminals when they are out of range or not actively using the smartphone.
Innovation Solution
A method and apparatus that allow multiple terminals equipped with cellular communication chips to communicate voice calls using the same phone number by implementing a call forwarding service, where a representative terminal detects specific criteria such as distance or application usage to transfer voice calls to an auxiliary terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple terminals are equipped with cellular communication chips, then communication capability is improved, but device complexity increases
Solution Approach 1:
Multiple terminals share a single phone number through call forwarding service, merging the communication identity function across multiple devices. The representative terminal consolidates the phone number assignment, while auxiliary terminals access the same number via automatic call transfer, reducing the need for separate number management.
Solution Approach 2:
The call forwarding service enables a single phone number to serve multiple terminals universally. The representative terminal can forward calls to different auxiliary terminals based on predefined conditions, making the phone number multi-functional across different devices and usage scenarios.
2Ease of operation
If call forwarding service is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The call forwarding service operates automatically based on predefined conditions without requiring manual user intervention. The representative terminal autonomously monitors conditions (such as proximity or application usage) and executes call forwarding decisions, eliminating the need for users to manually manage call routing.
Solution Approach 2:
Call forwarding rules and conditions are configured in advance before actual call scenarios occur. The system pre-establishes which auxiliary terminals should receive forwarded calls under specific conditions, enabling automatic execution when conditions are met without requiring real-time user decisions.
3Productivity
If automatic call forwarding based on conditions is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The representative terminal continuously monitors system conditions (such as terminal proximity, application usage state, or network status) and uses this feedback to dynamically control call forwarding behavior. When conditions change, the system automatically adjusts whether to forward calls, ensuring optimal communication routing based on real-time status.

The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as a smart home, a smart building, a smart city, a smart car, a connected car, health care, digital education, a smart retail, and security and safety services. A method and an apparatus for communicating voice calls in a communication system are provided. The apparatus includes a first terminal that is a representative terminal configured to receive a voice call sets up a function for using a call forwarding service with a second terminal that is an auxiliary terminal, when the first terminal detects an occurrence of an event complying with a certain criterion for performing a call forwarding service, to determine whether a call forwarding service with the second terminal is being executed, and to execute, unless the call forwarding service is being executed, the call forwarding service and to transfer a voice call received by the first terminal to the second terminal.
