Abstract
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.
