Local MBMS Configuration Mediation for VAL Server File Delivery

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions for local MBMS in V2X communications do not provide an easy way for the VAL server to utilize the service API provided by the underlying NRM server, and interactions between the V2X application specific server and the VAE server do not consider local MBMS delivery.

Innovation Solution

The VAL server acts as a requesting entity to use local MBMS information configured in the NRM server, which provides the relevant configuration, and local MBMS configuration in the NRM server considers VAL service ID when activating MBMS bearers, enhancing file delivery interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the VAL server directly configures local MBMS information, then the configuration flexibility is improved, but the device complexity and difficulty of maintaining consistency increase

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an NRM server as an intermediary between the VAL server and the MBMS configuration system. The NRM server stores and manages local MBMS information, acting as a mediator that provides configuration data to the VAL server without requiring the VAL server to directly maintain or update these configurations. This resolves the contradiction by allowing the VAL server to access configurations flexibly while the NRM server handles the complexity of configuration management and consistency maintenance.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If local MBMS information is pre-configured in the NRM server, then the ease of operation for VAL server is improved, but the adaptability to different VAL services decreases

Engineering Contradiction:

Improveease of operationVSAvoidservice adaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic configuration system where the NRM server stores multiple local MBMS information sets that can be selected and activated based on different VAL service requirements. The system dynamically retrieves and applies appropriate configurations from the NRM server based on service type, ensuring both ease of operation (automatic retrieval) and adaptability (multiple configuration options available).

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system allows different local MBMS information parameters to be configured and selected based on service requirements. The NRM server maintains multiple configuration sets with varying parameters, and the VAL server can request specific configurations based on service needs, achieving both operational simplicity and service adaptability through parameter-based configuration selection.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If the VAL server makes MBMS decisions autonomously, then the productivity is improved, but the reliability of using correct configurations decreases

Engineering Contradiction:

Improvedecision-making efficiencyVSAvoidconfiguration accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent establishes a feedback mechanism where the VAL server requests local MBMS information from the NRM server based on service requirements, and the NRM server provides verified configuration data in response. This feedback loop ensures that the VAL server makes autonomous decisions with high productivity while relying on the NRM server's centralized configuration management to ensure reliability and correctness of the configurations used.
