MOBILE COMMUNICATION METHOD, MOBILITY MANAGEMENT NODE, PACKET SWITCH, AND MOBILE STATION

摘要

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.

1. A mobile communication method comprising steps of:
transmitting, by a mobility management node, a bearer disconnection request signal including barring time to a mobile station when the mobility management node disconnects the bearer between the mobile station and a packet data network due to a failure in gateway equipment or the mobility management node in a state in which the bearer is established; and barring, by the mobile station, a mobile originating call directed to the packet data network based on the barring time included in the bearer disconnection signal, wherein at the step of transmitting the bearer disconnection request signal, the mobility management node decides to bar the call origination directed to the packet data network and transmits the bearer disconnection request signal, when the mobility management node detects the failure.
