Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2V communication systems face limitations in expanding transmission range and efficiency due to blind forwarding channel determination, leading to signaling overhead, delay, and air interface burden.
Innovation Solution
A forwarding control method and apparatus that determine the distribution state of neighboring terminals to select an appropriate forwarding mode, using different types of forwarding nodes such as neighboring terminals and base stations to optimize data forwarding, thereby avoiding these issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If blind forwarding channel determination is used, then forwarding can be performed, but signaling overhead and air interface burden increase
Solution Approach 1:
The patent implements dynamic forwarding mode selection that adapts to changing distribution states of neighboring terminals. The system transitions between different forwarding modes (direct forwarding, indirect forwarding, base station forwarding) based on real-time conditions, optimizing forwarding efficiency while minimizing signaling overhead for each specific scenario
Solution Approach 2:
The patent changes the parameter of forwarding mode selection based on the distribution state of neighboring terminals. By monitoring terminal distribution parameters and adjusting the forwarding mode accordingly, the system achieves efficient forwarding without incurring unnecessary signaling overhead
2Area of stationary object
If multiple forwarding attempts are performed to expand transmission range, then broader coverage is achieved, but transmission delay increases
Solution Approach 1:
The patent performs preliminary determination of the distribution state of neighboring terminals before initiating data forwarding. By pre-assessing the terminal distribution scenario, the system can directly select the most appropriate forwarding mode, avoiding multiple trial forwarding attempts and thereby reducing transmission delay while ensuring coverage
Solution Approach 2:
The patent introduces base stations as intermediary forwarding nodes when terminal distribution conditions are unfavorable for direct V2V forwarding. This intermediary approach enables broader coverage through cellular network infrastructure without requiring multiple V2V forwarding hops, thus reducing overall transmission delay
3Ease of operation
If V2V communication is used for data transmission, then direct vehicle-to-vehicle communication is achieved, but transmission range is limited
Solution Approach 1:
The patent creates a universal forwarding system that can operate in multiple modes: direct V2V forwarding when terminals are nearby, indirect V2V forwarding through intermediate terminals, and base station forwarding when terminals are far apart. This multi-functional approach maintains the ease of direct V2V communication while extending the transmission coverage area through alternative forwarding paths
Data Source
AI summary
A forwarding control method and a forwarding control apparatus is provided. A method comprises: at least determining, in response to a forwarding demand of measured data of at least one mobile terminal, a distribution state of neighboring terminals associated with a forwarding expectation of the measured data of the at least one mobile terminal; and determining, at least according to the distribution state, a forwarding mode of the measured data corresponding to the distribution state. In response to a forwarding demand of measured data, a corresponding forwarding mode can be selected according to a distribution state of neighboring terminals, so as to avoid problems, such as signaling overhead, delay, and an over heavy air interface burden, which may be caused by blindly determining a forwarding channel, and assist in implementing more effective forwarding.
