NFC-Enabled Handheld Session Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for a slave mobile device to join a conference call or share content with a master mobile device are complex, expensive, and require additional services not supported by all Mobile Network Operators, especially when devices are not collocated.
Innovation Solution
A communication system using near field communication (NFC) devices and wireless interfaces like Bluetooth or Wi-fi to establish a direct communication link between master and slave handheld devices, allowing the slave device to join an existing session without user intervention and at no additional cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional conference call services are used to enable a slave mobile phone to join a pre-established call, then the slave device can join the session, but the user must manually suspend the call, dial the slave phone, and link the calls through complex procedures provided by the Mobile Network Operator
Solution Approach 1:
The patent introduces a near field communication device as an intermediary between the master and slave mobile phones. This intermediary enables automatic identification and connection establishment when the devices are held next to each other, eliminating the need for manual call suspension, dialing, and linking procedures through the Mobile Network Operator.
Solution Approach 2:
The near field communication devices exchange identification information in advance when held next to each other, before the actual session joining occurs. This preliminary action of exchanging identification data through NFC enables the subsequent automatic establishment of the communication link without requiring user intervention during the joining process.
2Ease of operation
If additional conference call services are used to enable session joining, then the slave device can join the session, but additional fees are charged to the caller's account
Solution Approach 1:
The patent extracts the session joining function from the conventional Mobile Network Operator conference call service and implements it locally through near field communication between devices. By taking out the identification exchange and connection establishment processes from the network operator's domain and performing them locally via NFC, the solution eliminates the need for additional charged conference call services.
Solution Approach 2:
The master and slave mobile phones perform the session joining process themselves through direct near field communication, without requiring the Mobile Network Operator's conference call service infrastructure. The devices self-serve by exchanging identification information and establishing their own communication link, thereby avoiding additional fees charged by network operators for conference call services.
3Reliability
If manual procedures are used to establish communication link for sending pictures or joining calls, then the communication can be established, but the user must go through multiple menu steps and activate various services
Solution Approach 1:
The near field communication device serves as an intermediary that automatically handles the exchange of identification information and initiation of the communication link. This intermediary function replaces the need for users to manually navigate through multiple menu steps and activate various services, making the process as simple as holding the devices next to each other.
Solution Approach 2:
The communication link establishment process is automated through self-service mechanisms where the near field communication devices automatically exchange identification information and initiate the link creation without user intervention. The system performs the complex procedures of menu navigation and service activation automatically, maintaining reliability while dramatically improving ease of operation.
