    • PROBLEM TO BE SOLVED: To preferentially transfer an IMS call control signal of a priority call by preferentially establishing an IMS call control signal bearer of a priority call than an IMS call control signal bearer of a normal call when a priority call has been received by a mobile terminal UE. SOLUTION: A mobile communication method includes a step of determining, in the case where a priority control node PCRF is notified of the fact that an Invite signal including priority call information has been received from a call control node P-CSCF, whether it is necessary to change an ARP of a call control signal bearer for transmitting the Invite signal to the mobile terminal UE from a gateway device P-GW into ARP having a priority higher than a priority preset for the call control signal bearer, a step of changing, in the case where it has been determined that the ARP is necessary to be changed, the ARP of the call control signal bearer into ARP higher than the ARP preset for the call control signal bearer, and a step of performing paging with respect to the mobile terminal UE in accordance with the priority of the call control signal bearer.

    • PROBLEM TO BE SOLVED: To control barring of access for an "MMTEL origination call" even when a wireless base station eNB cannot transmit the SSAC barring information of Rel.9 system of LTE. SOLUTION: In a mobile station UE, an AS layer function 10 includes a system information receiving unit 11 which receives system information containing first barring information for use in a mobile communication system of Rel.8 system of LTE from the wireless base station eNB, an adjustment unit 13 which generates second barring information for use in the mobile communication system of Rel.9 system of LTE based on the AC of the mobile station UE and the first barring information, and a notification unit 14 which notifies the second barring information to an MMTEL/IMS layer function 30, wherein the MMTEL/IMS layer function 30 is equipped with a determination unit 24 which determines whether origination processing can be carried out or not based on the second barring information.

    • PROBLEM TO BE SOLVED: To suppress unnecessary position registration even when start, correction or deletion of a bearer is performed in a mobile communication system to which ISR is applied. SOLUTION: A mobile communication method has: a process in which when a bearer state is changed in a cell under a WCDMA type mobile communication system in a state where the position of a mobile station UE is registered in a WCDMA type exchange station SGSN and an LTE type exchange station MME, synchronizing processing for a bearer state of the mobile station UE is performed between the WCDMA type exchange station SGSN and the LTE type exchange station MME; and a process in which the WCDMA type exchange station SGSN notifies the mobile station UE about the execution of the synchronizing processing. When the mobile station UE receives the notification even when the bearer state is changed, the position of the mobile station UE is not registered in the LTE type exchange station MME when the mobile station UE is moved from a cell under the WCDMA type mobile communication system to a cell under the LTE type mobile communication system.
