Abstract

A method of canceling a location information request is disclosed, in which if a location server having received a location information request about a specific terminal from an external client is unable to forward location information of the terminal to the external client, the location server can cancel the location information request without a cancellation request from the external client. The location information request cancellation message may be selected among a Triggered Location Report message or a Triggered Location Reporting Stop Answer message or among a Standard Location Immediate Report message or a Standard Location Immediate Stop Answer message according to a location information request message.
