Problems solved by technology

In this case, re-searching will increase the server load, so even if the route is re-searched, the phenomenon of navigating the same route occurs frequently, resulting in waste of system resources

Abstract

The invention discloses a communication-based navigation system that detects a traffic volume change and searches for a route. The system comprises a terminal retaining geographic information and generating a route request and a traffic condition check request; a service server receiving the route request from the terminal, searching for a route, transmitting the searched route to the terminal and a traffic analysis server, and receiving a traffic condition check request signal and sending the signal to the traffic analysis server; and the traffic analysis server that stores in a corresponding database the searched route from the service server and traffic conditions in the searched route and sends a traffic condition change result to the terminal via the service server by comparing a stored traffic condition in the database with a current traffic condition of the searched route after the traffic condition check request signal is received.

Description

technical field [0001] The invention relates to a communication type navigation system which searches for a route by sensing changes in traffic volume. In particular, it relates to a communication-type navigation system that stores the traffic volume in units of routes and compares it with the current traffic volume to determine whether re-searching of the route is necessary to adjust the frequency of re-searching. Background technique [0002] The content described in the background section is only to provide background information and does not constitute prior art. [0003] After receiving the route from the server, the communication-type navigator uses the route received by the terminal to realize navigation through maps and languages. In this case, since the route is provided using the traffic information, a faster route can be provided. In general, TPEG (Transport Protocol Expert Group) or other communication-based navigators automatically re-search at a period of 5 t...
