Seamless Network Switching via Pre-Stored Device IDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods for portable electronic devices require users to manually reconnect and reestablish communication links when switching between different networks, such as from computer to telephone networks, which is inconvenient and time-consuming, especially when the computer network coverage is lost.
Innovation Solution
A method where a first electronic device automatically obtains the identification number of a third device on the target network, sends a linking request, and transfers ongoing data transmissions to the new network, allowing seamless switching without user intervention, by using built-in telecommunication address book software or manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual reconnection and reestablishment of communication links is used when switching between networks, then users can maintain communication, but the process becomes inconvenient and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-obtaining the identification number of the third electronic device before actual network switching occurs. The first electronic device stores the identification number in advance from the built-in telecommunication address book, so when network switching is needed, the device can immediately send a linking request without requiring manual user input or time-consuming search operations. This pre-preparation significantly reduces the time and effort required for network switching.
2Reliability
If automatic link maintenance through UMA technique is used, then communication continuity is improved, but infrastructure requirements and capital costs increase significantly
Solution Approach 1:
The patent extracts the core functionality needed for network switching from the complex UMA infrastructure. Instead of requiring automatic link maintenance through sophisticated UMA protocols and infrastructure, the invention isolates the essential element - obtaining and using the identification number of the target device - to achieve network switching. This simplification maintains communication reliability while eliminating the need for complex infrastructure changes and reducing capital costs.
3Loss of energy
If computer network is used for cost-effective data transmission, then communication cost is reduced, but network coverage and accessibility are limited
Solution Approach 1:
The patent applies dynamics by enabling the first electronic device to dynamically switch between different communication networks (computer network and telephone network) based on coverage availability. The device can start with cost-effective computer network communication when available, and automatically transition to telephone network when computer network coverage is lost. This dynamic adaptability ensures both cost efficiency and continuous connectivity across varying network conditions.

AI summary
A method for switching communication network used in a first electronic device which is able to access many kinds of communication networks is disclosed. If the first electronic device receives a switching instruction at a time when a communication link and a data transmission have been established between the first electronic device and a second electronic device via a first communication network. Firstly, the first electronic device obtains an identification number of a third electronic device for use in a second communication network. Then, the communication link is established between the first electronic device and the third electronic device via the second communication network according to the identification number. Finally, the data is transmitted using the communication link between the first electronic device and the third electronic device via the second communication network, and disconnects the original communication link via the first communication link.
