Location information system and method for performing notification based upon location
First Claim
1. A location based notification method in a method for calculating a location of a terminal by exchanging messages between a location server and the terminal according to a client'"'"'s request, the location based notification method comprising:
- receiving a SUPL INIT (Secure User Plane Location Initialization) message from the location server before establishing a connection with the location server, the SUPL INIT message including a notification mode parameter,wherein the notification mode parameter indicates whether or not a notification and verification based on a location of the terminal are to be performed after the location of the terminal is calculated, andwherein the notification is for requesting a response indicating whether or not provision of the calculated location of the terminal to the client is allowed, and the verification is for providing the response indicating whether or not the provision of the calculated location of the terminal to the client is allowed;
checking the received notification mode parameter to determine whether the notification and verification based on the location of the terminal are to be performed;
starting a positioning session with the location server in order to obtain the calculated location of the terminal;
sending a SUPL NOTIFY RESPONSE message to the location server in response to a SUPL NOTIFY message received from the location server, if the notification mode parameter indicates that the notification and verification based on the location of the terminal are to be performed;
before a releasing step, receiving a session end message after receiving the SUPL NOTIFY message when the notification mode parameter indicates that the notification and verification based on the location of the terminal are to be performed; and
releasing the connection with the location server after sending the SUPL NOTIFY RESPONSE message to the location server and after receiving the session end message.

Abstract
A system and method for performing a notification based upon location in a Secure User Plane Location (SUPL) network which is provided with a SUPL Location Platform (SLP) and a SUPL Enabled Terminal (SET) to thus perform a privacy authentication based upon a location of the SET, wherein when a client requests positioning of the SET, the SLP transmits a notification mode parameter to the SET through a session initial message, whereby it can be predefined whether the notification is performed based upon a location or a user when the SLP (i.e., server system) notifies the SET (or the SET user) of the positioning of the SET requested by the client (i.e., a client system), thus to enable the SET to determine a time point of a notification response.

6. A mobile communications terminal for providing location information in response to a client'"'"'s request, the mobile communications terminal comprising:
-
a radio frequency unit configured to receive, before establishing a connection with a location server, from a location server a SUPL INIT (Secure User Plane Location Initialization) message including a notification mode parameter, wherein the notification mode parameter indicates whether or not a notification and verification based on a location of the terminal are to be performed after the location of the terminal is calculated, and wherein the notification is for requesting a response indicating whether or not provision of the calculated location of the terminal to the client is allowed, and the verification is for providing the response indicating whether or not the provision of the calculated location of the terminal to the client is allowed; and a signal processing unit configured to check the received notification mode parameter to determine whether the notification and verification based on the location of the terminal are to be performed, wherein the radio frequency unit and the signal processing unit further cooperate to start a positioning session with the location server in order to obtain the calculated location of the terminal, to send a SUPL NOTIFY RESPONSE message to the location server in response to a SUPL NOTIFY message received from the location server if the notification mode parameter indicates that the notification and verification based on the location of the terminal are to be performed, to receive a session end message after receiving the SUPL NOTIFY message when the notification mode parameter indicates that the notification and verification based on the location of the terminal are to be performed, and to release the connection after sending the SUPL NOTIFY RESPONSE message to the location server and after receiving the session end message.
