Abstract: 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.
Abstract translation: 提供了一种用于定位移动终端的方法。 首先,响应于来自客户端的位置服务请求来检查要确定其位置的目标移动终端的归属公共陆地移动网络(PLMN)的信息。 然后,基于家庭PLMN的检查信息来检查目标移动终端当前所在的被访问PLMN的信息。 归属PLMN使用所访问的PLMN的特定位置信息来计算访问的PLMN的位置辅助信息。 定位辅助信息被传送到目标移动终端。 这允许获得移动终端的位置信息,而与移动终端所在的区域或通信网络无关。 因此,可以将移动终端定位在不提供定位辅助信息的区域中。
