Summary:Even if a failure has occurred in core network equipment in a state in which bearers are established between a large number of UEs and a packet data network, congestion in the network is avoided. A mobile communication method according to the present invention includes steps of transmitting, by an MME, to transmit a "PDN Disconnection Request/ Detach Request" including barring time to a UE when the MME disconnects a bearer between the UE and the packet data network due to a predetermined reason such as a failure in a S-GW/ P-GW or the MME in a state in which the bearer is established, and barring, by the UE, a mobile originating call directed to the packet data network for the barring time.
