receiving a SUPL TRIGGERED RESPONSE message from the server in response to sending a SUPL TRIGGERED START message to the server in order to start an area event triggered session with the SET, wherein the SUPL TRIGGERED START message comprising a session-id, a location-id, and SET capabilities, and the SUPL TRIGGERED RESPONSE message comprises at least one of a session-id, a positioning method, trigger parameters, and location identifiers of an area specified for the area event triggered session; sending a SUPL POS INIT message to the server to start the area event triggered session, when a comparison performed by the SET of a current area-id and the location identifiers of the area specified for the area event triggered session indicates that positioning of the SET is to be executed; exchanging, with the server, positioning procedure messages to calculate actual positioning information indicating longitudinal and latitudinal values of the SET when the SET operates in SET-assist mode;
