Location information system and method for performing notification based upon location
First Claim
1. A location based notification method in a H-SLP (Home-SUPL (Secure User Plane) Location Platform) for calculating and providing a location of a roaming terminal according to a client'"'"'s request, the method comprising:
- receiving, by the H-SLP, a client'"'"'s request for positioning of a roaming terminal;
transmitting, by the H-SLP, a SUPL INIT (SUPL Initialization) message to the roaming terminal before a connection with the roaming terminal is established, the SUPL INIT message including a notification mode parameter indicating whether or not a notification and verification based on the location of the roaming terminal are to be performed after the location of the roaming terminal is calculated;
requesting, by H-SLP, an initial location of the roaming terminal to a V-SLP (Visited-SUPL (Secure User Plane) Location Platform) thereby to receive the initial location of the roaming terminal;
performing, by the H-SLP, a positioning process to calculate the location of the roaming terminal if a required quality for the received initial location of the roaming terminal is not satisfied;
after the location of the roaming terminal is calculated through the positioning process, transmitting, by the H-SLP, a SUPL NOTIFY message including a notification element to the roaming terminal if the notification mode parameter indicates that the notification and verification based on the location of the roaming terminal are to be performed;
receiving, by the H-SLP from the roaming terminal in response to the SUPL NOTIFY message, a SUPL NOTIFY RESPONSE message that includes a verification indicating whether to allow or not allow a provision of the calculated location of the roaming terminal to the client; and
transmitting, by the H-SLP, the calculated location of the roaming terminal in response to the received SUPL NOTIFY RESPONSE message when the received SUPL NOTIFY RESPONSE message includes the verification indicating to allow the provision of the calculated location of the roaming terminal to the client.

Abstract
According to an embodiment, a location based notification method in a H-SLP (Home-SUPL Location Platform) receiving, by the H-SLP, a request for positioning of a roaming terminal; transmitting a session initialization message including a notification mode parameter to the roaming terminal when one or more of the location-based notification and verification are required as a result of checking a privacy of the roaming terminal; requesting, an initial location of the roaming terminal to a V-SLP (Visited-SUPL Location Platform) thereby to receive the initial location; and performing a positioning process to calculate the location of the roaming terminal if the required quality for the received initial location of the roaming terminal is not satisfied.
