Navigation system using a paging channel and a method for providing traffic information
First Claim
1. A navigation system utilizing a paging channel of a mobile communication service for a navigation apparatus including a mobile communication function, the navigation system comprising:
- a BSC-based traffic server for periodically extracting/synthesizing traffic information in an area of a BSC and then transmitting the traffic information in the area which is controlled by the BSC; and
a BSC for inserting the traffic information received from the BSC-based traffic server into the paging channel for a mobile communication terminal and then transmitting the paging channel.

Abstract
A navigation system utilizing a paging channel of a mobile communication service for a navigation apparatus including a mobile communication function is disclosed, which comprises: a BSC-based traffic server for periodically extracting/synthesizing traffic information in an area of a BSC, and then transmitting the traffic information of a peripheral area including the BSC; and a BSC for inserting the traffic information received from the BSC-based traffic server into the paging channel for a mobile communication terminal, and then transmitting it. In the navigation system, traffic conditions information in a corresponding area is transmitted by means of a paging channel, thereby utilizing real time traffic information while maintaining the architecture of the existing mobile communication network without an additional apparatus and communication cost.

7. A navigation apparatus including a mobile communication function for a navigation system utilizing a paging channel of a mobile communication service, the navigation apparatus including a mobile communication function comprising:
-
a paging channel analyzing means for analyzing a paging channel transmitted from a BTS and determining whether the navigation apparatus has entered a new BSC area or whether traffic information has been upgraded;
a decoding means for decoding the traffic information included in the paging channel for any one of a case in which the navigation terminal has entered the new BSC area and a case in which the traffic information has been upgraded, on the basis of the analysis result of the paging channel analyzing means; and
an optimal path calculation means for calculating an optimal path by means of the traffic information decoded by the decoding means. - View Dependent Claims (8, 9)

10. A method for searching for an optimal path in real time by means of a navigation system utilizing a paging channel of a mobile communication service, the method comprising the steps of:
-
(1) receiving entire optimal path information for a starting point and a destination and storing the entire optimal path information;
(2) receiving paging signals through a BTS, analyzing the paging signals, extracting traffic information included in the paging signals, and then storing the extracted information;
(3) when the extracted traffic information is updated traffic information, calculating an optimal path in a corresponding BSC area by means of the updated traffic information; and
(4) replacing a corresponding part of the optimal path in step (1) with the optimal path in step (3), and then storing the replaced optimal path. - View Dependent Claims (11, 12)
