Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for automobiles in dynamic mapping scenarios face challenges in achieving reliable communication due to the inability to establish redundant configurations with multiple base stations, leading to communication interruptions and delays in dynamic information provision.
Innovation Solution
A communication device that includes a base station search unit, a communication control unit, and a communication terminal search unit to establish redundantly-configured communication paths by enabling direct communication with base stations and indirect communication via selected communication terminals, allowing for the construction of redundant communication paths even when direct communication with base stations is limited.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a redundant configuration with multiple base stations is implemented, then communication reliability is improved, but device complexity and accommodation capacity requirements increase
Solution Approach 1:
The patent introduces a relay station as an intermediary component that enables indirect communication between the mobile station and base stations. The relay station acts as a mediator that receives signals from one base station and transmits them to the mobile station, allowing the mobile station to establish redundant communication paths without directly connecting to multiple base stations simultaneously. This resolves the contradiction by providing communication reliability through redundancy while avoiding the complexity of direct multi-base station configuration.
2Reliability
If indirect communication via relay is used, then redundant communication paths are established, but communication delay increases
Solution Approach 1:
The patent implements dynamic path selection and switching mechanisms that allow the system to adaptively choose between direct and indirect communication paths based on current conditions. The mobile station can dynamically switch between primary and redundant communication paths, and the system can adjust relay station selection and communication routing in real-time. This resolves the contradiction by minimizing communication delay through dynamic optimization while maintaining reliability through the availability of redundant paths.
Solution Approach 2:
The patent establishes redundant communication paths and relay station connections in advance before communication interruptions occur. The system proactively configures multiple communication paths and selects relay stations beforehand, so that when a communication failure occurs, the switch to the redundant path can happen immediately without significant delay. This resolves the contradiction by preparing the redundant infrastructure in advance, ensuring both reliability and minimal delay during actual communication operations.
3Ease of operation
If mobile station selection for relay is automated, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the mobile station autonomously performs relay station selection and communication path management without requiring manual configuration or complex external control. The mobile station automatically evaluates available relay stations, selects the most suitable ones based on predefined criteria, and manages the indirect communication paths independently. This resolves the contradiction by improving ease of operation through automation while keeping device complexity manageable through standardized, self-contained selection algorithms executed by the mobile station itself.

AI summary
A communication device has a function of directly communicating with a communication terminal that is another communication device, and includes: a base station search unit that searches for base stations with which direct communication is possible; a communication control unit that performs a connection process for connecting to base stations searched for by the base station search unit to construct redundantly-configured communication paths; and a communication terminal search unit that searches for the communication terminal connected to a base station, and in a case where the number of direct communications with base stations established is less than the number required for constructing the redundantly-configured communication paths, the communication control unit establishes indirect communication with a base station via a communication terminal searched for by the communication terminal search unit to construct redundantly-configured communication paths.
