METHOD OF CALCULATING ROUTE, AND METHOD OR DEVICE FOR OBTAINING ROUTE
First Claim
1. A method of, at a server, determining whether re-calculation of a route for a trip identified by a departure point and a destination is required using traffic information, the method comprising:
- receiving a current location of a terminal from the terminal when the terminal moves from a previously reported location by a specific distance;
acquiring a current location of a third party when the destination is a location of the third party defined by an identifier (ID) of the third party; and
determining whether re-calculation of the route is required according to specific conditions based on the acquired current location of the third party,wherein the specific conditions include;
(1) the third party moves from a previously reported location by a predetermined distance or more, or(2) the third party does not move from the previously reported location by the predetermined distance or more and a distance between the current location of the terminal and the current location of the third party is less than a threshold value, andwherein, if one of the specific conditions is satisfied, a determination is made that re-calculation of the route is required.

Abstract
A method of determining whether there is a need to re-calculate a trip route including a departure point and a destination by using traffic information according to an embodiment of the present invention is provided. The method is performed by a server and includes: receiving the current position from a terminal when the terminal moves a specific distance from a previously reported position; obtaining the current position of a third party when the destination is the position of the third party defined as the identifier (ID) of the third party; and determining whether there is a need to re-calculate the route according to a specific condition based on the obtained current position of the third party, wherein the specific condition is (1) when the third party moves a distance equal to or greater than a predetermined value from the previously reported position or (2) when the third party moves a distance equal to or greater than a predefined value from the previously reported position and the distance between the current position of the terminal and the current position of the third party is shorter than a critical value, and if one of the specific conditions is satisfied, it may be determined that there is a need to re-calculate the route.

6. A method of, at a terminal, determining whether re-calculation of a trip route identified by a departure point and a destination is required using traffic information, the method comprising:
-
transmitting a current location of the terminal to a server when the terminal moves from a previously reported location by a specific distance; and receiving a current location of a third party and updated traffic information of an ongoing route from the server, when the destination is a location of the third party defined by an identifier (ID) of the third party and a determination is made that re-calculation of the route is required according to specific conditions based on the current location of the third party, wherein the specific conditions include; (1) the third party moves from a previously reported location by a predetermined distance or more, or (2) the third party does not move from the previously reported location by the predetermined distance or more and a distance between the current location of the terminal and the current location of the third party is less than a threshold value, and wherein, if one of the specific conditions is satisfied, a determination is made that re-calculation of the route is required. - View Dependent Claims (7, 8, 13)

9. A server configured to determine whether re-calculation of a trip route identified by a departure point and a destination is required using traffic information, the server comprising:
-
a transceiver configured to communicate with a terminal; and a processor configured to provide traffic information of a route received from the terminal, wherein the processor is configured to; receive a current location of the terminal from the terminal when the terminal moves from a previously reported location by a specific distance, acquire a current location of a third party when the destination is a location of the third party defined by an identifier (ID) of the third party; and determine whether re-calculation of the route is required according to specific conditions based on the acquired current location of the third party, wherein the specific conditions include; (1) the third party moves from a previously reported location by a predetermined distance or more, or (2) the third party does not move from the previously reported location by the predetermined distance or more and a distance between the current location of the terminal and the current location of the third party is less than a threshold value, and wherein, if one of the specific conditions is satisfied, a determination is made that re-routing is required. - View Dependent Claims (10, 11, 12)

14. A terminal configured to determine whether re-calculation of a trip route identified by a departure point and a destination is required using traffic information, the terminal comprising:
-
a transceiver configured to communicate with a server; and a processor configured to calculate a route based on traffic information of a route received from the server and/or a location of a destination, wherein the processor is configured to; transmit a current location of the terminal to the server when the terminal moves from a previously reported location by a specific distance, and receive a current location of a third party and updated traffic information of an ongoing route from the server, when the destination is a location of the third party defined by an identifier (ID) of the third party and a determination is made that re-calculation of the route is required according to specific conditions based on an ongoing location of the third party, wherein the specific conditions include; (1) the third party moves from a previously reported location by a predetermined distance or more, or (2) the third party does not move from the previously reported location by the predetermined distance or more and a distance between the current location of the terminal and the current location of the third party is less than a threshold value, wherein, if one of the specific conditions is satisfied, a determination is made that re-calculation of the route is required. - View Dependent Claims (15, 16)
