Service Control Entity for Cross-Network Intelligent Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for implementing intelligent network services restrict users to terminals of the same network type, preventing access from different networks and limiting the use of intelligent network features when a third party terminal is used for payment.
Innovation Solution
A method where a calling terminal sends a call request with information about a third party terminal and a called terminal to a service control entity, which authenticates the third party terminal and implements the intelligent network service if the authentication is successful, allowing users to access intelligent network services from different network types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user employs a terminal from a different network type to access intelligent network services, then the service accessibility and user experience are improved, but the network security and service authentication complexity increase
Solution Approach 1:
The patent introduces a service control entity as an intermediary between the calling terminal and the intelligent network service. This entity receives call requests from terminals of any network type, performs unified authentication using the third party terminal's information, and routes the call appropriately. The service control entity acts as a mediator that handles the complexity of multi-network authentication, allowing terminals from different networks to access intelligent network services without each terminal needing to implement complex authentication logic.
2Adaptability or versatility
If the system supports terminals from different networks to access intelligent network services, then the network compatibility is improved, but the service control and management complexity increase
Solution Approach 1:
The service control entity is designed with universal functionality to handle call requests from multiple network types (PSTN, mobile networks, etc.). It performs unified authentication using the third party terminal's information regardless of the calling terminal's network type, and can implement various intelligent network services (intra-group short number dialing, familiarity number service, pre-paid service) through a single unified interface. This multi-functional design enables network compatibility without proportionally increasing service control complexity.
3Ease of operation
If a third party terminal account is used for payment and service access, then the user convenience is improved, but the service authentication reliability may be compromised
Solution Approach 1:
The system performs preliminary authentication of the third party terminal's information before allowing service access. When a call request is received, the service control entity first verifies the authenticity of the third party terminal's information (such as account credentials, authorization codes) before implementing the intelligent network service. This preliminary authentication ensures that even though a third party account is being used for convenience, the service authentication reliability is maintained by verifying the legitimacy of the third party's authorization beforehand.

AI summary
A method for implementing an intelligent network service is disclosed, including: receiving, by a service control entity, a call request sent from a calling terminal, the call request including information about a third party terminal and an identification of a called terminal, and performing, by the service control entity, authentication of the third party terminal according to the information about the third party terminal; and implementing the intelligent network service according to the identification of the called terminal if the authentication is passed and the service control entity determines that a current call is the intelligent network service with which the third party terminal has been provided. With the present invention, when a user cannot use a third party terminal that has been provided with the intelligent network service, the user may employ a terminal from a different type of network to obtain the account and the intelligent network service features of the third party terminal, so as to facilitate the use for the user and to achieve good user experience. A system for implementing an intelligent network service and a service control entity are also disclosed.
