First Claim
Patent Images
1. A system for providing a location-based alert service to generate an alert upon monitoring a location of a mobile client relative to an alert zone, comprising:
- a client for inputting a location alert generation condition for using the location-based alert services;
a location-based alert server for receiving location information on the mobile client to minimize the number of location inquiries using a moving distance ratio and a moving direction of the mobile client;
a location information DB for receiving and storing the location information on the mobile client from the location-based alert server; and
a location alert service server for receiving and storing the location alert generation condition from the client, and determining whether the mobile client exists in an alert range set by the client by receiving a location data of the mobile client from the location-based alert server to thereby generate an alert.

Abstract
Disclosed is a method and a system for providing a location-based alert service in a wireless communication environment, wherein, in a case where a specific user is located in a certain zone using a mobile communication terminal and a mobile communication network, the number of location inquiries is minimized using a moving distance ratio, a moving direction and a Minimum Bounding Rectangle (MBR) in providing the a location-based alert service for informing that the specific user is located in a certain zone.

12. A system for providing a location-based alert service to generate an alert upon monitoring a location of a mobile client relative to an alert zone, comprising:
-
a client for inputting a location alert generation condition for using the location-based alert service; a location-based alert server for receiving location information on the mobile client to minimize the number of location inquiries using an increase/decrease ratio of areas between a Minimum Bounding Rectangle (hereinafter, referred to as “
MBR”
) for a current moving location of the mobile client and the MBR up to the location of the mobile client, which has been obtained at a previous time;a location information DB for receiving and storing the location information on the mobile client from the location-based alert server; and a location alert service server for receiving and storing the location alert generation condition from the client, and determining whether the mobile client exists in an alert range set by the client by receiving a location data of the mobile client from the location-based alert server to thereby generate an alert. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for providing a location-based alert service, wherein the number of location inquiries is minimized in a case where a mobile client enters an alert zone, comprising the steps of:
-
(a) calculating a moving distance ratio of the mobile client; (b) adjusting a location inquiry request time interval by using a current moving distance of the mobile client, lower and upper limit values of the current moving distance, and the moving distance ratio; (c) adjusting the location inquiry request time interval by using a current and previous distances of the mobile client and the alert zone; and (d) setting the location inquiry request time interval as an initial location inquiry time interval if the mobile client enters a buffer zone. - View Dependent Claims (23, 24, 25, 26, 27, 38)

28. A method for providing a location-based alert service, wherein the number of location inquiries is minimized in a case where a mobile client leaves from an alert zone to an external zone, comprising the steps of:
-
(a) calculating a moving distance ratio of the mobile client; (b) adjusting a location inquiry request time interval by using a current moving distance of the mobile client, lower and upper limit values of the current moving distance, and the moving distance ratio; (c) adjusting the location inquiry request time interval using the current and previous distances of the mobile client and the alert zone; and (d) setting the location inquiry request time interval as an initial location inquiry time interval if the mobile client enters a buffer zone. - View Dependent Claims (29, 30, 31, 32, 33, 34)
