Method for transmitting location information
First Claim
1. A method of providing location information of a first SUPL Enabled Terminal (SET) at a Home SUPL location platform (H-SLP) which is a network server to a second SET using a Secure User Plane Location (SUPL) protocol in a communication environment, the method comprising:
- receiving, by the H-SLP, a SUPL START message from the first SET initiating a positioning procedure for transferring location information of the first SET to the second SET via the H-SLP, the SUPL START message including a session identifier, SET capabilities, SET-id information which is an identifier of the second SET, and mode type information which designates either one of the first SET or the second SET to receive the location information of the first SET;
transmitting, by the H-SLP, a SUPL RESPONSE message to the first SET, the SUPL RESPONSE message including the session identifier and a positioning method which is to be used for a positioning procedure between the H-SLP and the first SET;
receiving, by the H-SLP, a SUPL POS INIT message from the first SET, the SUPL POS INIT message including the session identifier and SET capabilities;
calculating the location information of the first SET through a direct connection between the H-SLP and the first SET based on the positioning method, the positioning method being one of a SET-assisted positioning method and a SET-based positioning method;
transmitting, by the H-SLP, a SUPL END message to the first SET to inform the end of a SUPL session, the SUPL END message including the session identifier; and
transmitting, by the H-SLP, the location information of the first SET to the second SET, after the SUPL session is finished.

Abstract
A method for transmitting location information includes the steps of: a) receiving a start message including MO (mobile originated location request) mode information from a first terminal; b) calculating location information of the first terminal; and c) transmitting the calculated first terminal'"'"'s location information according to the MO (mobile originated location request) mode information. A method for transmitting location information in a Secure User Plane Location (SUPL) protocol of a first SUPL Enabled Terminal (SET), a SUPL Location Platform (SLP), and a second SUPL Enabled Terminal (SET) includes the steps of: a) receiving a start message including MO (mobile originated location request) mode information from the first SET; b) calculating location information of the first SET; and c) transmitting the calculated first SET'"'"'s location information to any one of the first SET and the second SET according to the MO (mobile originated location request) mode information.

12. A method of providing location information of a first SUPL Enabled Terminal (SET) to a second SET using a Secure User Plane Location (SUPL) protocol in a communication environment, the method comprising:
-
transmitting, by the first SET, a SUPL START message to a Home SUPL location platform (H-SLP) which is a network server, to initiate a positioning procedure for transferring location information of the first SET to the second SET via the H-SLP, the SUPL START message including a session identifier, SET capabilities, SET-id information which is an identifier of the second SET, and mode type information which designates either one of the first SET or the second SET to receive the location information of the first SET; receiving, by the first SET, a SUPL RESPONSE message from the H-SLP, the SUPL RESPONSE message including the session identifier and a positioning method which is to be used for a positioning procedure between the H-SLP and the first SET; transmitting, by the first SET, a SUPL POS INIT message to the H-SLP, the SUPL POS INIT message including the session identifier and SET capabilities; performing a positioning procedure through a direct connection between the H-SLP and the first SET based on the positioning method to calculate the location information of the first SET, the positioning method being one of a SET-assisted positioning method and a SET-based positioning method; and receiving, by the first SET, a SUPL END message from the H-SLP, the SUPL END message including the session identifier and informing the first SET of an end of a SUPL session, wherein the location information of the first SET is transmitted by the H-SLP to the second SET. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
