MOBILE COMMUNICATION METHOD MOBILITY MANAGEMENT NODE PACKET EXCHANGE DEVICE AND MOBILE STATION

摘要

When a bearer is established between a large number of UE and a packet data network even if a malfunction occurs in a core network device congestion in the network can be avoided. A mobile communication method according to the present invention comprises a step for transmitting a 'PDN disconnection Request/detach Request' including restriction time to UE when a bearer is established between the UE and a packet data network and if an MME disconnects the bearer due to a predetermined reason such as a malfunction in a S GW/P GW or the MME and a step in which the UE restricts the transmission to the packet data network during the restriction time.
