摘要:
A method for providing triggered location information of a target terminal is provided. The method includes transmitting by a previous H-SLP a report message informing that a target terminal is in a roaming state during the triggered location service to an H-SLP of the target terminal or the target terminal. The H-SLP of the target terminal selects a new V-SLP based on a location identifier (LID) received from the target terminal, and the H-SLP provides the V-SLP with an ID of the target terminal, a positioning method of the target terminal (SET CAPABILITY), and the LID as the information on the network in which the target terminal currently exists. The newly selected V-SLP determines the positioning method and protocol used for the positioning with the target terminal by using the SET CAPABILITY, the newly selected V-SLP transmits its own IP address and the newly determined positioning method and protocol (POSMETHOD) to the H-SLP. The H-SLP transmits the IP address of the newly selected H-SLP and the new POSMETHOD to the target terminal, the target terminal transmits a positioning inducing message to the new V-SLP and calculates a location value by using the determined POSMETHOD, in such a manner that the triggered location service is maintained even though the target terminal is in a roaming state during the service by performing the step of selecting the H-SLP for calculating the location value of the target terminal without interruption.
