摘要:
A method and an apparatus for selecting a location platform for a user equipment to roam and a method for determining the location of the user equipment using the same. The method for selecting a location platform includes: checking a visiting network of the UE in response to a location request message transmitted from the UE which is roaming; and selecting a location platform to calculate a location of the UE by comparing positioning capability information of the checked visiting network and positioning capability information of a home network of the UE. According to such a method, it is possible to efficiently perform the positioning of the UE, regardless of the location of the UE, thereby improving the quality of the positioning service.

A method and apparatus for calculating a location of a User Equipment (UE) that is roaming, the method including receiving, by a Home Location Platform (HLP), a location request message from the UE for starting a positioning session with the UE, wherein the location request message includes specific identifier information of an area in which the UE is located, and positioning capability information including a positioning scheme supported by the UE, determining that the HLP calculated a position estimate, transmitting a request for an approximate coordinate information to a Visiting Location Platform (VLP), receiving the approximate coordinate information from the VLP, exchanging location information with the UE, and calculating a position of the UE using the exchanged location information. According to such a method, it is possible to efficiently perform the positioning of the UE, regardless of the location of the UE, thereby improving the quality of the positioning service.

A method for locating mobile terminals is provided. First, information of a home Public Land Mobile Network (PLMN) of a target mobile terminal, the location of which is to be determined, is checked in response to a location service request from a client. Then, information of a visited PLMN, where the target mobile terminal is currently located, is checked based on the checked information of the home PLMN. The home PLMN calculates location assistance information of the visited PLMN using specific location information of the visited PLMN. The location assistance information is transferred to the target mobile terminal. This allows location information of a mobile terminal to be obtained irrespective of the area or communication network where the mobile terminal is located. It is thus possible to locate a mobile terminal in an area where no location assistance information is provided.

Disclosed is a method for determining a location of a UE by means of AGPS information. The method includes generating by an SLC a pseudo UE ID according to a request for location information of the UE, the pseudo UE ID being used for maintaining security in communication with an SPC, requesting AGPS information for the UE, the location information of which has been requested, to the SPC by means of the pseudo UE ID, and receiving the AGPS information, transferring the received AGPS information to the UE, and receiving GPS signal measurement values using the AGPS information from the UE, requesting a location calculation of the UE for the GPS signal measurement values to the SPC by means of the pseudo UE ID, and receiving calculated location values, and providing the location information of the UE by means of the received location values of the UE.
摘要:
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.

A method and apparatus are disclosed for providing location information of a User Equipment (UE) in a communication system including the UE, a Secure User Plane Location (SUPL) Location Center (SLC), and a SUPL Positioning Center (SPC). The method includes receiving, by the SLC, a request for the location information of the UE from a requester; notifying, by the SLC, the UE that the location information has been requested; transmitting, by the SLC to the SPC, a pseudo IDentifier (ID) for securing a connection between the SPC and the SLC; receiving, by the SLC from the SPC, the location information of the UE with the pseudo ID, the location information of the UE being calculated by the SPC, based on a positioning measurement measured by the UE; and transmitting, by the SLC, the location information to the requester.
