- a client for sending a location request message for requesting a location of a target terminal; and
a location server for receiving the location request message, determining if a location request condition set by the client is included in the location request message, calculating location information of the target terminal, determining if the location request condition is satisfied when the location request condition is included in the location request message, and sending a location response message including the calculated location information to the client, when the location request condition is satisfied.

Abstract
A common location service request/response method between various types of clients and location servers. A location request and a location estimate are delivered between a terminal and a location server using messages defined in a Session Initiation Protocol (SIP) protocol. In this manner, the terminal and server using the SIP protocol can easily send a request/response for location information, making it possible to provide a new service associated with the location service.
