Navigation Terminal Partial Route Update Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems experience inefficiencies in route and real-time traffic information delivery, leading to unnecessary data transmission and repeated recalculations without actual route modifications, which can degrade service quality and user experience.
Innovation Solution
A method for calculating a route using updated traffic information, where the terminal compares and transmits only partial route modifications to the server, composed of consecutive segment sequences, along with performance parameters like speed, delay, and travel time, to optimize data transmission and reduce redundant recalculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal transmits the whole recalculated route to the server, then the server can provide real-time traffic information for the complete route, but unnecessary data transmission occurs when only partial route modifications are needed
Solution Approach 1:
The patent extracts and transmits only the modified portion of the route (partial route information) instead of the entire route. When the terminal recalculates a new route, it identifies only the segments that differ from the original route and transmits just those modifications to the server, thereby reducing unnecessary data transmission while maintaining route information accuracy.
Solution Approach 2:
The patent segments the route into multiple sections and transmits only the modified segments. By dividing the route into discrete segments and identifying which segments have changed, the system can transmit minimal data (only the modified segments) rather than the complete route, resolving the contradiction between reliability and energy loss.
2Productivity
If the terminal performs route recalculation based on updated traffic information, then real-time route optimization is achieved, but repeated recalculations without actual modifications waste computational resources
Solution Approach 1:
The patent implements a feedback mechanism where the terminal compares the recalculated route with the original route before transmission. The system receives feedback from the server about whether the recalculation resulted in actual modifications, and only transmits route information when genuine changes occur, thereby preventing wasted computational resources on redundant recalculations.
Solution Approach 2:
The patent applies partial action by performing route recalculation only when necessary and transmitting only the modified portions. Instead of continuously recalculating and transmitting complete routes, the system performs partial recalculations based on updated traffic information and transmits only the necessary modifications, optimizing productivity while minimizing time loss.
3Reliability
If the server provides real-time traffic information for the entire route, then complete route monitoring is achieved, but data transmission volume increases unnecessarily
Solution Approach 1:
The patent extracts and transmits only the necessary traffic information for the modified route segments rather than providing complete route information. By identifying which segments have changed and transmitting traffic information only for those segments, the system maintains reliability of traffic information while significantly reducing the quantity of data transmitted between terminal and server.

AI summary
According to one embodiment of the present invention, a method is disclosed for calculating the route of a journey (trip) identified by an origin and a destination using traffic information on a terminal, wherein the method comprises the steps of: receiving updated traffic information relating to a first route, while the terminal or a moving object on which the terminal is mounted is running on the first route; calculating a second route by using the updated traffic information; and transmitting, to a server, an entire route or a partial route of the calculated second route. Here, the calculated second route is compared with the first route, information about a partial route comprising one or more changed segment sequences is transmitted to the server, the segment sequence comprises one or more continuous segments, and the information relating to the partial route can comprise first segment information and final segment information about the segment sequence of the first route that will be substituted by respective segment sequences comprised in the partial route.
