Abstract: To avoid a phenomenon that a UE cannot transmit uplink packets even when a TAU/RAU process, handover process, or radio switching process of the UE frequently occurs and an S-GW to which the UE is to be connected is frequently changed in an EPC network to which PMIPv6 is applied. A mobile communication system including an EPC network to which PMIPv6 is applied is configured such that a S-GW#2 determines whether or not to transmit the RA to the UE based on RA transmission information transmitted by a P-GW, when the S-GW to which the UE is to be connected is changed from an S-GW#1 to the S-GW#2 by the TAU/RAU process, handover process, or radio switching process.
