Abstract
In a mobile communication network, a controlling node receives capability information from a mobile terminal, indicating positioning methods supported by the mobile terminal and selectability of the positioning methods. In response to a location request message from a client terminal requesting the location information of a target mobile terminal, the controlling node transmits a first control message via a wireless node to the target mobile terminal, containing a copy of requested accuracy of the location information, if the capability information indicates that the target mobile terminal is capable of selecting positioning methods. The mobile terminal performs measurement according to a positioning method that satisfies the requested accuracy. Otherwise, the controlling transmits a second control message to the mobile terminal, specifying a positioning method. In this case, the mobile terminal performs measurement according to the specified positioning method.
