Digital Device Additional Service Identity Module for Operator-Independent Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital processing devices, such as portable terminals, are limited to accessing only the communication network of their subscribed operator, restricting their ability to receive additional services without additional authentication and subscription to specific communication operators.
Innovation Solution
Incorporating an additional service identity module within the digital processing device, which allows users to access various additional services by generating an additional service request message using an identity code and authentication information, independent of the subscribed communication operator, enabling connection to any communication network device using a control signal to selectively drive the subscriber or additional service identity unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users subscribe to a specific communication operator to access additional services, then they can receive services from that operator, but they are restricted from accessing services from other operators without additional subscription
Solution Approach 1:
The patent segments the identity module into two distinct parts: a subscriber identity module (SIM) for communication operator authentication and an additional service identity module for service provider authentication. This segmentation allows independent management of communication subscription and service access, enabling users to access services from multiple operators without additional subscriptions.
Solution Approach 2:
The additional service identity module provides universal access to additional services across different communication operators. By incorporating this module, the terminal device gains the ability to authenticate with multiple service providers through a single interface, making the system multi-functional in terms of service access while maintaining simple subscription management.
2Adaptability or versatility
If additional service providers are subordinated to communication operators, then service delivery is controlled, but additional service providers cannot independently provide services to users
Solution Approach 1:
The patent separates the authentication functions into distinct modules: the subscriber identity module handles communication operator authentication while the additional service identity module handles service provider authentication. This segmentation enables additional service providers to operate independently without being subordinated to communication operators, as they have their own dedicated authentication module.
Solution Approach 2:
The additional service identity module acts as an intermediary between the terminal device and additional service providers. It facilitates direct authentication and service access between users and service providers, eliminating the need for service providers to be subordinated to communication operators while maintaining simple and direct service provision.
3Adaptability or versatility
If users only access services from their subscribed communication operator, then subscription management is simple, but users cannot access services from other operators
Solution Approach 1:
The patent divides the identity management system into two separate modules: the subscriber identity module for communication operator access and the additional service identity module for service provider access. This segmentation allows users to access a variety of services from multiple operators while maintaining a clear and organized identity module structure that does not unnecessarily complicate the device.
Solution Approach 2:
The additional service identity module provides universal access to additional services across multiple communication operators. By incorporating this module, the terminal device achieves multi-functionality in service access, enabling users to access diverse services from different operators without significantly increasing device complexity, as the module integrates seamlessly with the existing SIM card infrastructure.

AI summary
A digital processing device capable of receiving an additional service is disclosed. In one aspect, a digital processing device includes i) an input unit, inputting a signal, ii) a subscriber identity unit, storing an identity code of a communication operator and generating a communication network access request message, iii) an additional service identity unit, storing an identity code of an additional service operator and generating an additional service request message and v) a control unit, generating a control signal allowing one of the subscriber identity unit and the additional service identity unit to be selectively driven. In accordance with at least one inventive embodiment, a user of the digital processing device can receive an additional service without his or her subscription to a specific communication operator and use various additional services in addition to the additional services provided by the subscribed communication operator.
