Abstract

According to an embodiment, a location based notification method in a system including a H-SLP (Home-SUPL Location Platform), and a V-SLP (Visited-SLP) having a V-SLC (Visited-SUPL Location Center) and a V-SPC (Visited-SUPL Positioning Center) for a location service, 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; transmitting and receiving, by the V-SPC, messages with the roaming terminal for performing a positioning process if a positioning start message is received from the roaming terminal.

Claims

1. A location based notification method in a system including a H-SLP (Home-SUPL (Secure User Plane Location) Location Platform), and a V-SLP(Visited-SLP) having a V-SLC (Visited-SUPL Location Center) and a V-SPC (Visited-SUPL Positioning Center) for a location service, 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;

transmitting and receiving, by the V-SPC, messages with the roaming terminal for performing a positioning process if a positioning start message is received from the roaming terminal;

transferring, by the V-SPC, a report message including the positioned location of the roaming terminal to the H-SLP through the terminal;

transmitting, by the H-SLP, a session notification message including a notification element to the terminal if one or more of notification and verification based upon the location are required;

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

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

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 the one or more 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 roaming 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, the session notification message is a SUPL NOTIFY message, and the session notification response message is a SUPL NOTIFY RESPONSE message.

6. The method of claim 4, wherein the end message is a SUPL END 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-SLC 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-SLC.

8. The method of claim 1, wherein the notification element is a notification parameter, and the notification response is a notification response parameter.
