Policy-Based Reliability Control for eV2X Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In enhanced vehicle-to-everything (eV2X) wireless communication networks, existing technologies lack effective mechanisms for managing transmission control and reliability requests, which can lead to inefficient use of radio resources and unauthorized applications accessing higher transmission priorities.
Innovation Solution
A policy-based control mechanism that authorizes reliability requests at the non-access stratum protocol layer, determining if applications are authorized to make such requests and modifying or denying them based on pre-configured policies, ensuring only authorized applications use higher transmission features like packet duplication and carrier aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transmission control is allowed for all applications, then transmission flexibility is improved, but radio resources are wasted by unauthorized applications
Solution Approach 1:
The patent introduces a policy framework as an intermediary between applications and the transmission control system. This framework mediates by evaluating application authorization status and transmission requests against predefined policies, allowing flexible transmission control for authorized applications while blocking requests from unauthorized applications, thus preventing radio resource waste
Solution Approach 2:
The patent implements preliminary authorization evaluation before allowing transmission control. Applications must be pre-authenticated and their transmission requests pre-evaluated against policies before actual transmission occurs. This preliminary action ensures only authorized applications can access transmission control features, preventing resource waste while maintaining flexibility for legitimate uses
2Speed
If reliability requests are processed without authorization control, then transmission speed is improved, but unauthorized applications access higher transmission priorities
Solution Approach 1:
The policy framework acts as an intermediary layer that sits between the application layer and the transmission processing layer. It mediates by inserting authorization evaluation into the request flow, checking application status and policy compliance before allowing reliability requests to be processed, thus maintaining transmission speed for authorized applications while preventing unauthorized access to high priorities
Solution Approach 2:
The system implements feedback mechanisms where authorization decisions are based on continuous evaluation of application status and policy compliance. The framework provides feedback to both the network and application about authorization status, ensuring that only compliant applications receive enhanced transmission treatment, thereby maintaining security while preserving performance for legitimate uses
3Reliability
If policy-based control is implemented at non-access stratum layer, then authorization control is improved, but device complexity increases
Solution Approach 1:
The patent implements the policy framework at the non-access stratum layer, which serves multiple functions: authorization evaluation, policy enforcement, and transmission control coordination. This multi-functional approach consolidates complexity into a single framework rather than distributing it across multiple separate systems, improving authorization control while managing overall system complexity
Solution Approach 2:
The patent segments the policy control functionality into distinct components within the non-access stratum layer, separating authorization evaluation logic from transmission processing logic. This segmentation allows for modular implementation and easier maintenance, reducing the practical complexity of deploying and managing the authorization control system while maintaining robust policy enforcement

AI summary
A method, apparatus, and computer-readable medium for transmission control include receiving, at a non-access stratum protocol layer, a packet including a reliability request from an application, and determining if the application is authorized to make the reliability request. Further, the aspects include, in response to determining the application is authorized to make the reliability request, performing one of: sending the packet including the reliability request to an access stratum protocol layer, or sending the packet with a modified reliability request to the second protocol layer. Additionally, the aspects include transmitting the packet. Further aspects describe a control plane delivery mechanism for provisioning UE, such as with policies and/or configurations including transmission control reliability authorization information.
