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.
