Telematics Status Query for Reliable Data Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in providing data-related services to telematics-equipped vehicles due to uncertainties in the operational status of these devices, leading to unnecessary communications and increased costs.
Innovation Solution
A method that involves sending a status request message to a wireless carrier system to gather status information, determining the vehicle's registration and authentication status, and establishing a mobile-terminated data connection only if the vehicle is capable of receiving services, with the option to send a monitor request if the vehicle is not registered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If status information is gathered before establishing data connection, then service reliability is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by querying the operational status of the telematics device before establishing a data connection. The system checks registration status, authentication status, and other relevant status information in advance to determine whether the device is capable of receiving data services, thereby preventing failed connections and improving service reliability.
Solution Approach 2:
The patent uses an intermediary approach by introducing a status information query mechanism between the service provider and the telematics device. This intermediary status check acts as a mediator that verifies device readiness before the actual data connection is established, reducing the complexity of handling connection failures and improving overall system reliability.
2Loss of energy
If status check is performed before data connection, then unnecessary communications are reduced, but time for service setup increases
Solution Approach 1:
The patent performs status information gathering as a preliminary action before initiating data connection establishment. By querying operational status, registration status, and authentication status in advance, the system identifies incompatible or unavailable devices beforehand, preventing wasted communication attempts and reducing overall communication costs.
Solution Approach 2:
The patent implements feedback by using the status information obtained from the telematics device to make informed decisions about connection establishment. The system uses feedback from status queries to determine whether to proceed with data connection, thereby avoiding unnecessary communications and reducing energy consumption while maintaining efficient service setup.

AI summary
A communications method that gathers status information on a telematics-equipped vehicle before establishing a mobile-terminated data connection with that vehicle. In general, the communications method sends a status request message to a wireless carrier system that asks for certain status information on a particular telematics-equipped vehicle. After the wireless carrier system gathers the status information, it sends back a status response message. If the status response message indicates that the telematics-equipped vehicle is able to receive certain data-related services, then a mobile-terminated data connection is established and the services are provided. If the telematics-equipped vehicle is unable to receive the data-related services, then attempts are made to identify and resolve the problem. In cases where the telematics-equipped vehicle is not registered with a wireless network, a monitor request message is sent to the wireless carrier system which puts it on the lookout for registration of the vehicle in question.
