Abstract
Disclosed is a Location Based Service (LBS) system for providing location information of a target terminal for positioning. Such a LBS system can provide both a requester for location information as well as a third party specified by the requester with the location information by means of only one request message for the location information. The LBS system includes a requester terminal requesting location information of a specific terminal, and a LBS provider receiving a request for the location information from the requester terminal and providing the requester terminal with the location information. The LBS provider receives information on at least one terminal specified to simultaneously receive the location information, along with the request message for the location information, from the requester terminal, whereby the LBS provider delivers the location information to the at least one specified terminal along with the requester terminal.
