Abstract
The communication system according to the present invention includes: a mobile deviceconnectable to an LTE system and a 3G system; and an RNCconfigured to control mobility of the mobile devicebetween the LTE system and the 3G system. When the mobile device sends the RNCa request for connection to the 3G system instead of the LTE system because the LTE system imposes access restriction to restrict communication performed by the mobile device, the mobile deviceincorporates mobility information in the request for connection, the mobility information indicating that the mobile device hands over from the LTE system. In addition, when acquiring the mobility information from the mobile device, the RNCrestrains the mobile devicefrom handing over to the LTE system.
