Engineering Contradiction Analysis
1Reliability
If terminals use basic network selection methods without real-time information, then device complexity is reduced, but quality of service and connection cost optimization deteriorate
Solution Approach 1:
The network information providing device pre-collects and provides network characteristic information (bandwidth, latency, cost, user account parameters) to terminals before actual network selection occurs. This allows terminals to make informed decisions based on comprehensive data without implementing complex collection and analysis mechanisms themselves.
Solution Approach 2:
A network information providing device acts as an intermediary between the access networks and terminals. This mediator collects network status information from multiple networks and delivers it to terminals, simplifying the terminal's network selection mechanism while improving service quality through real-time information.
2Productivity
If terminals aggregate traffic on multiple access networks, then productivity is improved, but device complexity increases due to MPTCP protocol requirements
Solution Approach 1:
The system implements feedback mechanisms where the network information providing device continuously monitors network status (bandwidth availability, latency, user account parameters) and provides updated information to terminals. This enables dynamic traffic aggregation decisions based on real-time conditions without requiring complex terminal-side protocols.
Solution Approach 2:
The patent changes the approach from protocol-based aggregation (MPTCP) to parameter-based selection. By providing real-time network parameters (bandwidth, cost, latency) and user account information, the system enables flexible traffic distribution based on current conditions rather than requiring complex multi-protocol support in terminals.
3Loss of information
If terminals select networks without real-time performance information, then ease of operation is maintained, but loss of information increases leading to suboptimal decisions
Solution Approach 1:
The network information is segmented into distinct categories: network performance parameters (bandwidth, latency), user account parameters (data remaining, subscription level), and connectivity status. This structured information delivery allows terminals to process specific relevant data without being overwhelmed by comprehensive network details.

AI summary
Disclosed are a terminal able to be connected simultaneously to a plurality of access networks, a method for selecting an access network using the terminal, and a device and a method for providing characteristic information of an access network. The selection method, which can be implemented by a terminal, includes receiving an information packet from a device for providing characteristic information of an access network, the terminal being connected to this access network, and depending on the characteristic information obtained from the information packet, at least of maintaining a connection to at least one access network to which the terminal is already connected or connecting to at least one other different technology access network.
