Abstract
An RNC includes: a first call request reception unit configured to receive from an exchange a first call request to only an already located wireless cell; a presumably located wireless cell derivation unit configured to derive a presumably located wireless cell in which a target communication terminal device is presumably located; a first call making unit configured to make a call to the already located wireless cell and the presumably located wireless cell; a call response signal transmission unit configured to transmit a response signal to the call, to the exchange; a second call request reception unit configured to receive from the exchange a second call request to a wireless cell different from the already located wireless cell, in a case where the response signal to the first call request has not been transmitted; and a second call making unit configured to make the call to the different wireless cell.
