<p><P>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. <P>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. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
