Method for requesting triggered location service between terminals in location information system
First Claim
1. A method for requesting a triggered location service between terminals in a location information system, comprising:
- requesting, by a first terminal, a triggered location service of a second terminal in a certain area;
transferring the triggered location service request to a second network of the second terminal from a first network of the first terminal;
initiating a positioning session with the second terminal by the second network and calculating a location of the second terminal; and
comparing, by the second network, the thusly calculated location with the certain area set by the first terminal and notifying an area event occurrence in the certain area to the first terminal.

Abstract
Disclosed is a method for requesting a triggered location service between terminals in an SUPL-based location information system, and more particularly, a method for requesting a triggered location service related to an area event. When a triggered service of a second terminal is requested in a certain area from a first terminal, a network of the first terminal transfers the triggered service request to a second network of the second terminal. The second network initiates a positioning session with the second terminal, exchanges positioning messages and calculates a location of the second terminal, then compares the calculated location with a certain area set by the first terminal, and notifies area event occurrence in the certain area to the first terminal.
