Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques fail to appropriately switch connections between public and non-public networks for user terminals, leading to inefficient network utilization.
Innovation Solution
An information processing apparatus and method that includes a receiving unit to detect user terminal location changes between public and non-public networks and a control unit to disconnect public network communication and establish non-public network communication based on contract information, enabling seamless switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user terminal is connectable to both public network and non-public network, then network coverage and accessibility are improved, but appropriate network switching cannot be achieved
Solution Approach 1:
The system changes the parameter of network selection by using contract information (subscription data) to determine which network the terminal should connect to. The AMF node retrieves contract information from the UDM node and uses it to make switching decisions, transforming the network selection from a generic connectivity problem to a contract-based parameter-driven decision.
Solution Approach 2:
The system implements feedback by having the AMF node continuously monitor terminal location and network status, retrieve contract information, and make switching decisions based on this feedback loop. When the terminal moves between public and non-public networks, the system receives location feedback, checks contract eligibility, and executes appropriate switching actions.
2Ease of operation
If manual network switching is implemented, then connection control is achieved, but switching timeliness and automation are reduced
Solution Approach 1:
The system enables self-service by automatically performing network switching without manual user intervention. The AMF node autonomously retrieves contract information, determines the appropriate network based on terminal location and contract eligibility, and executes the switching decision, eliminating the need for manual control while reducing switching time.
Solution Approach 2:
The system performs preliminary action by pre-fetching contract information from the UDM node before switching is needed. The AMF node retrieves and stores contract information in advance, so when a switching decision is required, the information is already available, reducing the time needed for actual network switching.
3Speed
If network switching is automated based on location, then switching speed is improved, but accuracy of network selection deteriorates
Solution Approach 1:
The system changes the selection parameter from simple location-based switching to contract-information-based switching. By incorporating contract eligibility as a critical parameter alongside location data, the system maintains switching speed while improving selection accuracy to ensure terminals connect to networks they are authorized to use.

AI summary
To enable a user terminal to appropriately switch a connection between a public network and a non-public network.There is provided an information processing apparatus including: a receiving unit that receives information indicating that a user terminal, which is located in a base station of a public network and connected to the public network in such a way as to be capable of data communication, is located in a base station of a non-public network; and a control unit that controls, based on contract information of the user terminal, to disconnect data communication in the public network and transmit information for connecting data communication in the non-public network.
