Abstract

According to an embodiment, a location based notification method in a H-SLP (Home-SUPL Location Platform) includes 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 if one or more of location-based notification and verification are required as a result of checking a privacy of the roaming terminal; transferring a positioning start message to a V-SLP (Visited-SUPL Location Platform) if the H-SLP receives the positioning initialization message from the roaming terminal; receiving a calculated location of the roaming terminal from the V-SLP; and transmitting a session notification message including a notification element to the roaming terminal if the H-SLP receives the calculated location of the roaming terminal.

Claims

1. A location based notification method in a H-SLP (Home-SUPL 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 request for positioning of a roaming terminal;

transmitting, by the H-SLP, a session initialization message including a notification mode parameter to the roaming terminal if one or more of location-based notification and verification are required as a result of checking a privacy of the roaming terminal;

transferring, by the H-SLP, a positioning start message to a V-SLP (Visited-SUPL Location Platform) if the H-SLP receives the positioning initialization message from the roaming terminal;

receiving, by the H-SLP, a calculated location of the roaming terminal from the V-SLP;

transmitting, by the H-SLP, a session notification message including a notification element to the roaming terminal if the H-SLP receives the calculated location of the roaming terminal;

receiving, by the H-SLP, a session notification response message including a notification response by the user of the roaming terminal from the roaming terminal; and

transmitting, by the H-SLP, the location of the roaming terminal to a client who has requested the location of the terminal in response to the received session notification response message.

2. The method of claim 1, wherein the notification mode parameter further indicates a normal notification and verification.

3. The method of claim 2, wherein one or both of the normal notification and verification are performed for a user-based notification and verification.

4. The method of claim 1, further comprising:

transferring, by the H-SLP, an end message to the terminal before transmitting the location of the roaming terminal after receiving the session notification response message.

5. The method of claim 1, wherein the session initialization message is a SUPL INIT message, and the positioning start message is a SUPL POS INIT message.

6. The method of claim 1, wherein the session notification message is a SUPL NOTIFY message, and the session notification response message is a SUPL NOTIFY RESPONSE message.

7. The method of claim 1, further comprising:

transmitting, by the H-SLP, a message for notifying a start of positioning to the V-SLP before transmitting the session initialization message after receiving a request for positioning of the roaming terminal; and

receiving, by the H-SLP, a message for notifying that the start of positioning is prepared from the V-SLP.

8. The method of claim 4, further comprising:

receiving the end message from the V-SLP to the H-SLP wherein in the step of transmitting the end message the received end message is transferred.

9. The method of claim 1, wherein the notification mode parameter is a Notification Mode parameter, the notification element is a Notification parameter, and the notification response is a Notification Response parameter.
