Positioning apparatus and method of a mobile terminal using a positioning server independently constructed on a network
First Claim
1. A positioning apparatus of a mobile terminal, comprising:
- a positioning server, independently constructed on a network, for collecting, storing, and managing assistant data that includes orbit information and correction information of a satellite, and for providing one of the assistant data and position information using the assistant data in response to an external request;
wherein the positioning server provides the position information of the terminal subject to positioning in response to the request for the position information of the terminal subject to positioning created from at least one network among a plurality of networks that share the positioning server.

Abstract
A positioning apparatus and method of a mobile terminal using a positioning server independently constructed on a network. The positioning apparatus includes a positioning server, independently constructed on a network, for collecting and storing/managing assistant data that includes orbit information and correction information of a satellite, and providing the assistant data or position information using the assistant data in response to an external request. The positioning server provides the position information of the terminal subject to positioning in response to the request for the position information of the terminal subject to positioning created from at least one network among a plurality of networks that share the positioning server. Accordingly, an accurate positioning result can be obtained with a cost for implementation of the positioning system reduced.

5. A positioning method of a mobile terminal using a positioning server independently constructed on a network, the method comprising the steps of:
-
receiving a request for position information of the mobile terminal;
calculating physical position information corresponding to logical position information about a visited network of the mobile terminal in response to the position information request;
transferring the physical position information to the positioning server;
receiving assistant data of the mobile terminal from the positioning server;
calculating the position of the mobile terminal using the assistant data; and
transferring a result of calculation for the position of the mobile terminal. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A positioning method of a mobile terminal that is roaming to a visited network provided with a position calculation service module constructed independently of a positioning service permission module, the method comprising the steps of:
-
receiving a request to provide position information of the mobile terminal in a home network;
providing access information for a position calculation service module of the visited network to the mobile terminal;
accessing the position calculation service module of the visited network using the access information by the mobile terminal; and
calculating and determining the position of the mobile terminal by the position calculation service module. - View Dependent Claims (13, 14, 15, 16)

17. A positioning method of a mobile terminal in a network in which a position calculation service module is constructed separately from a positioning service permission module, the method comprising the steps of:
-
receiving a request for position information of the mobile terminal by the positioning service permission module of a home network;
providing access information for a position calculation service module located in a place that is near to the mobile terminal to the mobile terminal;
accessing the position calculation service module using the access by the mobile terminal; and
calculating the position of the mobile terminal using assistance data by the position calculation service module. - View Dependent Claims (18, 19, 20, 21)

22. A positioning method of a mobile terminal in a network in which a position calculation service module is constructed separately from a positioning service permission module, the method comprising the steps of:
-
if the position information of the mobile terminal is requested, receiving access information for a position calculation service module that is located in a place near to the mobile terminal from a home network by the mobile terminal;
accessing the position calculation service module using the accessing information; and
exchanging signal required for calculation of the position and data with the position calculation service module by the mobile terminal. - View Dependent Claims (23, 24, 25, 26)
