A control device (4) is configured so as to perform network level discovery including tracking of the current positions of first and second wireless terminals (1A, 1B) in order to detect proximity of the first and second wireless terminals (1A, 1B). The control device (4) is configured so as to acquire at least a position history for the first wireless terminal (1A) prior to beginning network level discovery as a result of a request for network level discovery from the first wireless terminal (1A). It is thus possible to improve, for example, the precision of determination of whether to begin network level discovery (e.g., EPC-level ProSe Discovery). |
