Common Delivery Platform for Mobile Services with Trust Model
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of diverse services over mobile telephony networks necessitates a unified platform that can manage different standards and protocols for real-time, web, and rich media services, while ensuring secure and efficient access for users with varying authentication levels, due to the complexity of multiple service providers and heterogeneous environments.
Innovation Solution
A system comprising multiple processing units with distinct execution environments for different services, a data structure for storing subscriber authentication data, and a trust model to determine access rights based on authentication levels, facilitating secure and efficient access to multiple services through a common user identity and service repository.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different service standards and protocols are implemented for different service types (real-time, web, rich media), then service diversity and functionality are improved, but system complexity and difficulty of management increase
Solution Approach 1:
The system segments service management into separate processing units, each dedicated to specific service types (real-time services, web services, rich media services). Each processing unit implements the appropriate standards and protocols for its designated service category, isolating complexity within manageable modules while maintaining overall system diversity.
Solution Approach 2:
A common delivery platform acts as an intermediary layer between multiple service providers and the network infrastructure. This platform provides unified access mechanisms and authentication services that work across different service types, reducing the complexity users face when accessing diverse services with different protocols.
2Adaptability or versatility
If multiple service providers host services in heterogeneous environments with different access policies, then service variety is improved, but user access complexity increases
Solution Approach 1:
The common delivery platform implements universal access mechanisms that work across all service providers and heterogeneous environments. A single authentication system and unified access interface enable users to access diverse services without needing to learn different access procedures for each provider, maintaining ease of operation despite service variety.
3Ease of operation
If federated identity scheme with single sign on is implemented across different service providers, then user access ease is improved, but authentication security and access control complexity increase
Solution Approach 1:
The authentication system is segmented into multiple processing units, each responsible for specific authentication data sets and trust relationships. This segmentation allows the system to manage complex authentication logic in isolated modules while presenting a simplified single sign-on interface to users.
Solution Approach 2:
The common delivery platform serves as an intermediary authentication authority that manages federated identity relationships between different service providers. It handles the complex trust model and authentication data set management internally, while users experience simplified single sign-on access across all services.
Data Source
AI summary
One embodiment of a system for providing services to subscribers of a network supports the provision of a plurality of different services to multiple subscribers. A processor arrangement is provided for hosting the different services. A data structure is provided for storing data associated with subscribers of the system, wherein data associated with subscribers of the system comprises a plurality of sets of data, each set of data relating to a respective level of authentication. A trust model comprises a set of relationships between the sets of data, and the trust model determines the access rights of subscribers to different services in dependence on the data set which has been used to authenticate the subscriber in a given subscriber session. The use of this trust model enables services and other access rights to be provided to a subscribed which match the level of authentication which has been applied to the subscriber during any particular session.
