Communication Controller Mode Switching for Vehicle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional base station devices for mobile communication do not provide a service that fully satisfies user needs in terms of convenience.
Innovation Solution
A communication device and method that allows communication with a base station or terminal device in either a first mode or a second mode, where the first mode offers better communication conditions, such as speed and quality, after completing a specific procedure different from the second mode, and includes a communicator and a communication controller to manage these modes, as well as a lock controller to unlock the vehicle door for user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If communication in the first mode (better conditions) is enabled, then communication speed and quality are improved, but the complexity of communication procedures increases due to requiring completion of a first procedure different from the second procedure
Solution Approach 1:
The terminal device performs the first procedure (including authentication and permission acquisition) in advance before establishing communication in the first mode. The base station device stores the acquired permission information and uses it to automatically enable the first mode without requiring repeated authentication, thus improving communication speed while managing procedure complexity through preliminary setup.
2Reliability
If communication in the first mode is permitted after completing a specific procedure, then communication quality is improved, but the ease of operation deteriorates due to the additional procedural requirements
Solution Approach 1:
The terminal device autonomously performs the first procedure to acquire permission information without requiring manual configuration or user intervention. The base station device automatically recognizes the permission information and switches to the first mode, making the system self-configuring and improving ease of operation while maintaining high communication quality.
3Reliability
If a distinct first procedure is required for first mode communication, then communication security is improved, but the time required for communication setup increases
Solution Approach 1:
The authentication and permission acquisition procedures are performed in advance during the first mode establishment. Once permission information is acquired and stored by the base station device, subsequent communications in the first mode can proceed without repeating the authentication process, thus maintaining security while reducing setup time for ongoing communications.

AI summary
A communication device includes a communicator controller. The communication controller configured to cause a communicator to communicate with a terminal device in a first mode or a second mode, in which the first mode is a mode in which communication conditions are better than in the second mode, and, when the communication controller has acquired permission information indicating that communication in the first mode is permitted according to completion of processing of a first procedure different from a second procedure required for communication in the second mode in response to a request from the terminal device, the communication controller causes the communicator to communicate with a terminal device associated with the permission information in the first mode.
