Data Card Authentication for CMMB Subscriber Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for playing China Mobile Multimedia Broadcasting (CMMB) services can only play clear program streams without authentication, limiting the control of subscriber authority by providers.
Innovation Solution
A method and apparatus that include a data card with an authentication adaptation layer module and a telecommunication basic service module, featuring intelligent USIM/SIM and SD card interfaces, which authenticate and authorize subscribers before transmitting CMMB data to terminal devices, enabling secure playback of encrypted streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a data card is used to receive clear program streams and transmit them to a terminal device, then the terminal device can play the programs, but the method can only play clear CMMB program streams without authentication, limiting the control of subscriber authority by the providers
Solution Approach 1:
The patent combines the authentication adaptation layer module with the data card hardware, merging authentication capabilities into the existing clear stream reception system. This integration allows the data card to handle both clear and encrypted streams while maintaining subscriber authority control through the embedded authentication module.
Solution Approach 2:
The data card is enhanced to perform multiple functions: receiving clear program streams, receiving encrypted program streams, performing authentication, and transmitting data to terminal devices. This multi-functionality resolves the contradiction by enabling both playback capability and authentication control within a single device.
2Adaptability or versatility
If authentication and authorization processes are added to the data card before transmitting CMMB data, then provider authority control is enhanced, but the system complexity increases with additional modules and interfaces
Solution Approach 1:
The authentication system is segmented into distinct functional modules: an authentication adaptation layer module that handles authentication logic, a telecommunication basic service module for communication, and intelligent USIM/SIM card interfaces for credential storage. This segmentation manages complexity by organizing functions into manageable, independent units.
Solution Approach 2:
The authentication adaptation layer module acts as an intermediary between the data card hardware and the authentication protocols. It mediates the authentication process by translating between different authentication methods (USIM/SIM card interface and SD card interface) and the underlying data transmission requirements, thereby managing system complexity through a standardized interface layer.
3Adaptability or versatility
If the data card supports both intelligent USIM/SIM card interface and SD card interface for authentication, then multiple authentication modes are enabled, but the device complexity and interface requirements increase
Solution Approach 1:
The data card incorporates both intelligent USIM/SIM card interface and SD card interface to support multiple authentication modes universally. This design allows the system to adapt to different authentication requirements and user preferences without requiring separate devices, resolving the contradiction by making the single data card universally compatible with multiple authentication methods.
Solution Approach 2:
The authentication system is designed to be dynamic, allowing the data card to switch between different authentication modes (USIM/SIM card authentication or SD card authentication) based on the specific service requirements and user configuration. This dynamic capability enables the system to adapt to different scenarios while maintaining a unified interface structure.
