FIELD: physics, communications.
SUBSTANCE: system includes home location platform (H-SLP) of secure user plane location (SUPL) protocol for transmission of message including previous position condition to target terminal (SET terminal) supporting SUPL protocol according to location service query from SUPL protocol agent; and target SET terminal for detection of position data saved earlier and meeting the condition of previous position in message, for defining position data by reiterated use of position data saved earlier if such data meeting the condition of previous position in message are present, and for providing position data to SUPL protocol agent.
EFFECT: improved efficiency of location.
