Vehicle Wireless Communication Control Unit Service State Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in appropriately processing service contracting and cancellation requests, particularly in ensuring that network communications are restricted or allowed based on the service state, and in handling emergency situations without unnecessary transmissions.
Innovation Solution
A wireless communication apparatus equipped with a control unit that manages a SIM card to rewrite service contract information, allowing or rejecting network transmissions based on service state requests from the network, and enabling emergency communications even in cancellation states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control unit restricts network communication when service is canceled, then network management reliability is improved, but emergency communication capability deteriorates
Solution Approach 1:
The patent applies local quality by differentiating communication handling based on service state: normal communications are restricted when service is canceled, while emergency communications maintain priority access. The control unit identifies emergency situations and applies different communication policies locally to emergency traffic versus regular traffic, ensuring reliable network management while preserving critical emergency capabilities.
2Adaptability or versatility
If the control unit allows all transmissions regardless of service state, then communication flexibility is improved, but network management control deteriorates
Solution Approach 1:
The patent implements dynamics by making communication permission dynamic rather than static. The control unit continuously monitors service state and automatically adjusts communication permissions accordingly. When service is active, communications are allowed; when service is canceled, normal communications are restricted while emergency communications maintain access. This dynamic adjustment ensures both network management control and appropriate communication flexibility.
3Measurement precision
If the control unit checks service state for every transmission request, then transmission accuracy is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by having the control unit determine service state in advance before transmission occurs. The service state is established and stored prior to any transmission request, allowing the control unit to quickly reference this pre-determined state rather than performing complex real-time verification for each transmission. This preliminary determination maintains transmission accuracy while minimizing processing time delays.

AI summary
A wireless communication apparatus mounted on a vehicle, the wireless communication apparatus includes: a wireless communication unit that performs wireless communication with a network; an information card on which information on a contract of a service provided from a communication carrier is recorded; and a control unit that rewrites the information recorded on the information card according to a request for contracting of the service or a request for canceling of the service transmitted from the network when contracting or canceling the service, wherein the control unit writes a cancellation state to the information of the information card according to the request for canceling transmitted from the network.
