Mobile Terminal Network Setup via Automatic Message Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals require complex network setup processes for IP-based WLAN communication, making it difficult for ordinary users to utilize WLAN services due to the need for manual IP address configuration and security settings, which are vulnerable to unauthorized access.
Innovation Solution
A method where a first mobile terminal generates and sends a network setup message over a mobile network to a second mobile terminal, including necessary setup information such as IP address, subnet mask, WEP, and network key, allowing automatic network setup and enhancing security by restricting access to authorized devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual network setup is used for WLAN communication, then network configuration can be customized, but the setup process becomes complex and difficult for ordinary users
Solution Approach 1:
The patent applies preliminary action by having the first mobile terminal pre-configure all necessary network setup information (IP address, subnet mask, WEP, network key) before communication begins. This pre-prepared configuration is then automatically transferred to the second terminal, eliminating the need for manual setup steps and making the process user-friendly while maintaining secure customized configuration.
2Ease of operation
If WLAN interface is kept on for frequent use, then access convenience is improved, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by completing all network configuration steps in advance through automatic message exchange. Once configured, the WLAN interface can be quickly activated without requiring users to go through complex setup procedures each time, thus improving access convenience while allowing the interface to remain off longer to save power.
3Reliability
If network security settings are implemented, then unauthorized access is prevented, but setup complexity increases
Solution Approach 1:
The patent applies self-service by having the first mobile terminal automatically generate and transfer security configuration information (WEP, network key) to the second terminal through message exchange. The system configures itself without user intervention, maintaining strong security settings while eliminating the complexity of manual security configuration for ordinary users.
4Ease of operation
If DHCP automatic assignment is used, then IP configuration is simplified, but network security control is reduced
Solution Approach 1:
The patent merges the advantages of both manual and automatic configuration by combining automatic message-based transfer with secure pre-configured settings. The first terminal automatically sends IP address, subnet mask, and security parameters to the second terminal, achieving both simplified operation (no manual input) and maintained security control (pre-set secure parameters).

AI summary
A method is provided for setting up a network for Internet Protocol (IP) communication between mobile terminals. A first mobile terminal determines a second mobile terminal that will communicate with the first mobile terminal. The first mobile terminal generates network setup information of the first mobile terminal for the IP communication and performs network setup using the network setup information. The first mobile terminal generates a network setup message including network setup information of the second mobile terminal, and sends the network setup message to the second mobile terminal.
