Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, distinguishing and connecting communication terminals to appropriate service networks without relying on network identification information like PLMN or APN is challenging due to limited configuration values and the need for multiple authentication servers, leading to difficulties in ensuring proper service network connectivity.
Innovation Solution
A core network apparatus with a reception unit to acquire terminal and base station identification information, a control unit to determine service association, and a transmission unit to provide connection information to the base station, allowing terminals to connect to appropriate service networks regardless of network identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different configuration values of PLMN or APN are used to distinguish service networks, then service network distinction is improved, but device complexity increases due to limited PLMN configuration values and the need for multiple authentication servers
Solution Approach 1:
The patent introduces a core network apparatus as an intermediary between the base station and service networks. This apparatus receives connection requests, determines the appropriate service network based on terminal and base station identification information, and forwards requests to the correct service network. This mediator approach eliminates the need for multiple authentication servers while maintaining reliable service network distinction.
Solution Approach 2:
The core network apparatus performs multiple functions: it acts as an authentication server, a service network selector, and a connection manager. By consolidating these functions into a single apparatus, the system avoids deploying multiple specialized authentication servers for different APNs, thereby reducing device complexity while maintaining service network distinction.
2Reliability
If multiple authentication servers are deployed for each APN to prevent unauthorized access, then service network security is improved, but device complexity increases due to the large number of required servers
Solution Approach 1:
The patent merges the authentication function with the service network selection function in a single core network apparatus. Instead of having separate authentication servers for each APN, the core network apparatus performs both authentication and service network determination based on terminal identification information, reducing the number of servers needed while maintaining security.
Solution Approach 2:
The core network apparatus serves as an intermediary that centralizes authentication and service network routing. By positioning this apparatus between the base station and multiple service networks, it can authenticate terminals and direct them to appropriate service networks without requiring individual authentication servers for each network, thus reducing complexity while maintaining security.
3Measurement precision
If network identification information is used for service network connection, then connection accuracy is improved, but adaptability decreases when configuration values are limited or changed
Solution Approach 1:
The core network apparatus uses feedback from terminal identification information and base station identification information to dynamically determine the appropriate service network. Instead of relying on fixed network identification information like APN that may be limited or changed, the system uses feedback from identification data to adaptively select service networks, maintaining both connection accuracy and adaptability.
Solution Approach 2:
The patent implements a dynamic service network selection mechanism where the core network apparatus determines service networks based on terminal and base station identification information rather than static configuration values. This dynamic approach allows the system to adapt to changes in terminal configurations and base station locations while maintaining accurate service network connections.

AI summary
A core network apparatus in which a communication terminal is connected to an appropriate service network without depending on network identification information is provided. A core network apparatus includes: a reception unit configured to acquire, when a service network that provides a service for a communication terminal and the communication terminal are connected to each other, identification information of the communication terminal and identification information of a base station included in a connection request message transmitted from the base station connected to the communication terminal; a control unit configured to determine whether a first service associated with the identification information of the communication terminal coincides with a second service associated with the identification information of the base station; and a transmission unit configured to transmit connection information of a service network that provides the second service to the base station when the first service coincides with the second service.
