System and method for providing mobility event triggered service of target set and target set

A method for providing a mobility event triggered service of a target set, and for providing a mobility triggered service to a Secure User Plane Location (SUPL) agent in a system having a Home SUPL Location Platform (H-SLP) for supporting the mobility triggered service, the SUPL agent for requesting the mobility triggered service in regard to a specific target set, and the specific target set, the method comprising:

• (a) transmitting a mobility triggered service request message in regard to the target set including an occurrence determination condition of the mobility triggered service from the SUPL agent to the H-SLP;
• (b) transmitting the mobility triggered service request message from the H-SLP to the target set;
• (c) sensing the start of the mobility triggered service according to the occurrence determination condition of the mobility triggered service, and storing information peculiar to an area where the target set is currently located by the target set;
• (d) comparing, by the target set, newly received subsequent information peculiar to an area with the previously stored information peculiar to the area if the subsequent information peculiar to an area is newly received;
• (e) determining, by the target set, that an event of the mobility triggered service occurs if there is a difference between the two pieces of information;
• (f) transmitting a report according to the mobility triggered service including a notice of an event occurrence from the target set to the H-SLP;
• (g) providing, by the H-SLP, the report according to mobility triggered service to the SUPL agent;
• and
• (h) repeating, by the target set and the H-SLP, steps (d) to (g) according to the occurrence determination condition of the mobility triggered service until the mobility triggered service is completed.

A target set in a system for providing a mobility triggered service, and having a Secure User Plane Location (SUPL) agent, the target set, and a Home SUPL Location Platform (H-SLP), the target set comprising:

• a receiving unit for receiving information corresponding to an area where the target set is currently located from an external entity of the target set if the mobility triggered service is started;
• a memory unit comprising:
• a first memory unit for storing information on an occurrence condition and a report condition of the mobility triggered service;
• a second memory unit for the received information corresponding to the area;
• and
• a third memory unit for storing information corresponding to an area which has been previously received from the receiving unit;
• a comparison processing unit for comparing the information corresponding to the area where the current target set is located at this point in time with the information corresponding to an area which has been received before this point in time, and for determining if there exists a difference between the two pieces of information;
• a report processing unit for generating a report giving notice that an event of the mobility triggered service occurs according to a condition of the report if it is determined that there exists the difference between the two pieces of information;
• and
• a transmission unit for transmitting the generated report to the H-SLP if the report is generated.
