The communication system according to the present invention includes: a mobile device 300 connectable to an LTE system and a 3G system; and an RNC 210 configured to control mobility of the mobile device 300 between the LTE system and the 3G system. When the mobile device sends the RNC 210 a 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 300, the mobile device 300 incorporates 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 300, the RNC 210 restrains the mobile device 300 from handing over to the LTE system.

Even when small cells formed by the Home Node B and the Home eNode B are concentrated, the Automatic Neighbor Relation (ANR) function is effectively performed. A mobile device 300 reports cell information including a setting status of a neighboring cell to an RNC 100 based on broadcasted system information received from the neighboring cell. The mobile device 300 determines a neighboring cell to be reported to the RNC 100 based on report-target cell information including at least a type of a neighboring cell to be reported to the RNC 100, and reports the cell information to the RNC 100 based on the broadcasted system information received from the neighboring cell thus determined.

A mobile communication method according to the present invention includes step A of instructing, by a radio access network apparatus of a first communication scheme, a mobile station having first radio connection established with the radio access network apparatus of the first communication scheme to switch to a mobile communication system of a second communication scheme, and step B of notifying the mobile station of a priority by the mobile communication system of the second communication scheme using a predetermined signal after the mobile station establishes second radio connection with a radio access network apparatus of the second communication scheme, the priority used to determine a communication system for camping-on by the mobile station.
摘要:
During a transition procedure from a first communication system to a second communication system, when the priority of a second communication call, whose setup is requested, is the first priority, the second communication system does not set up the bearer of a first communication call between the second communication system and the mobile communication terminal, and notifies the first communication system that the setup of the first communication is not possible, but the setup of the second communication call is possible. When notified that the setup of the first communication is not possible, but the setup of the second communication call is possible, the first communication system aborts the handover procedure, and instructs the mobile communication terminal to switch to the second communication system by another procedure.
