Abstract

A system and a method for providing a mobility event triggered service of a target set and the target set are provided. When a mobility triggered service is started, a target set stores a unique identifier related to an area where the target set itself is currently located, and compares a unique identifier stored at present while identifiers are continuously stored during an agreed time interval in the mobility triggered service with the unique identifier related to the area where the target set itself is currently located. If there is the difference between two unique identifiers, the target set stores the unique identifier related to the area where the target set itself is currently located, and with determination of its movement, determines that an event of the mobility triggered service happens. Then, the target set reports the occurrence of the event to an H-SLP, and the H-SLP begins to calculate position values of the target set according to a set condition of a current mobility triggered service. Next, the H-SLP transmits the calculated position value to a SUPL agent. Thus, if a position of the target set changes, the SUPL agent can detect a change of the position of the target set or can be supplied with information on a current position according to the position change of the target set.
