Multiple source location method

摘要

In a network for locating a user in e.g. a cellular telecommunication system (100) where location information is available to locate a particular user and multiple sources (110) of location information are available, the location information from different sources for each of the users is of different kinds and resolution. Among the currently available and valid location information for a user, the most recent location is first chosen as the preferred location information "L" indicating the probable location of the user. Then the valid locations are determined that have a higher resolution than the information "L". If there is no conflict with the information "L" the location information having a higher resolution will be selected. Each user has a software agent (130), which controls access to the location information and which performs the selecting of the probably true location information. It can receive location information through location services (120) converting location information from a set of sources. The selected location information can be forwarded from the agents to receiving services (150) through coordinating services (140).
