Network Access Control Agent for Converged Multimedia Resource Arbitration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing converged multi-media systems require separate services and complex logic on user equipment (UE) for managing shared resources, failing to account for dynamic factors like policies, presence, and profiles, leading to limitations in resource allocation and customization.
Innovation Solution
A data communication system with an access control agent that allocates UE resources based on profiles, presence, personalization, and policies, allowing for centralized decision-making and minimizing the need for local logic on the UE, using an access control agent to evaluate and assign resource access levels for multi-media sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate services and complex logic are implemented on UE for managing shared resources, then resource allocation can be performed, but device complexity and difficulty of customization increase
Solution Approach 1:
The patent extracts the resource arbitration logic from the UE device and relocates it to a network-based arbitration system. The access control agent on the network evaluates resource requests and makes allocation decisions, removing the need for complex local arbitration logic on each UE device while maintaining efficient resource allocation through centralized control
Solution Approach 2:
The patent introduces an access control agent as an intermediary component between services and UE resources. This mediator evaluates resource requests against policies, profiles, and presence information, then grants or denies access accordingly. This intermediary approach simplifies UE logic by offloading decision-making to the network while enabling dynamic, context-aware resource allocation
2Ease of operation
If separate services are provided on UE with awareness of common resources, then resource access can be managed, but adaptability to dynamic factors decreases
Solution Approach 1:
The patent implements dynamic resource arbitration by having the access control agent continuously evaluate resource requests against current policies, user profiles, and presence information. The arbitration decisions adapt in real-time to changing conditions such as user availability, service priorities, and resource status, enabling the system to respond dynamically to contextual factors without requiring service redesign
Solution Approach 2:
The patent changes the arbitration parameters from static service-level configurations to dynamic policy-based evaluations. The access control agent uses configurable policies, user profiles, and presence data as variable parameters that can be modified without changing the underlying service logic, allowing the system to adapt to different scenarios by adjusting policy parameters rather than rewriting service code
3Adaptability or versatility
If multiple enablers and applications are provided on UE, then service functionality increases, but system complexity increases
Solution Approach 1:
The patent implements a universal access control agent that handles resource arbitration for multiple service types through a single centralized component. Instead of requiring separate arbitration logic in each service or enabler, the access control agent provides a unified interface that manages resources for email, VoIP, video conferencing, and other services, reducing the number of components while maintaining service diversity
Solution Approach 2:
The patent segments the arbitration function from the service logic, creating a separate access control layer that handles resource management independently. This segmentation allows services to remain simple while the access control agent handles the complexity of resource coordination, enabling multiple services to coexist without increasing overall system complexity
4Reliability
If applications are written with knowledge of each other, then resource coordination is possible, but ease of manufacture and deployment decreases
Solution Approach 1:
The patent introduces an intermediary access control agent that mediates between applications and shared resources. Applications communicate their resource needs to the access control agent through standardized interfaces, and the agent coordinates access without requiring applications to have direct knowledge of each other. This intermediary approach maintains reliable resource coordination while simplifying application development and deployment
