V2X Application Server Service Classification via MBMS Bearers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X Application Servers face difficulties in forwarding different types of Vehicle-to-Everything (V2X) services effectively.
Innovation Solution
The method involves a V2X Application Server classifying V2X services by type, using unique identifiers, and sending request messages to a Broadcast Multicast Service Center to establish Multimedia Broadcast Multicast Service (MBMS) bearers, allowing for the forwarding of classified services through established MBMS bearers, which include Single Cell Point-to-Multipoint (SC-PTM) and Multimedia Broadcast Single Frequency Network (MBSFN) configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the V2X Application Server uses traditional forwarding methods, then the system structure remains simple, but it cannot effectively forward different types of V2X services
Solution Approach 1:
The patent segments V2X services into different types (periodic services and event-triggered services) and assigns different bearers to each type. The V2X AS classifies services based on their characteristics and routes them through appropriate bearers (MBMS bearers for periodic services, dedicated bearers for event-triggered services), enabling effective forwarding of diverse service types while maintaining clear structural organization.
Solution Approach 2:
The patent introduces the Broadcast Multicast Service Center (BM-SC) as an intermediary between the V2X Application Server and the network infrastructure. The BM-SC assists in establishing MBMS bearers and managing multicast service delivery, allowing the V2X AS to effectively forward periodic V2X services without directly handling the complexity of bearer management itself.
2Manufacturing precision
If the V2X Application Server classifies and routes different service types through different bearers, then service delivery accuracy improves, but the operational complexity increases
Solution Approach 1:
The patent implements preliminary classification of V2X services into periodic and event-triggered types before routing them to different bearers. The V2X AS pre-configures routing rules based on service characteristics, so that when services need to be forwarded, the appropriate bearer is automatically selected based on pre-established classification criteria, reducing real-time operational complexity while maintaining high delivery accuracy.

AI summary
Provided is a method for sending a V2X service. The method includes: a Vehicle-to-Everything (V2X) Application Server (AS) classifies and identifies the V2X service, where different types of V2X service have different identifiers; the V2X AS sends a request message to a Broadcast Multicast Service Center (BM-SC), where the request message is used for instructing the BM-SC to establish a Multimedia Broadcast Multicast Service (MBMS) bearing corresponding to an identifier of theV2X service; and the V2X AS sends the V2X service through the MBMS bearing established by the BM-SC. The above solution addresses the problem that it is difficult for the V2X AS to forward different types of V2X services in the related art.
