Claim:
1. A congestion control method by a mobility management entity (MME) in a mobile communication system, the method comprising: establishing one or more connections to one or more packet data networks (PDNs) with a terminal, based on one or more access point names (APNs), in response to receiving one or more PDN connection requests from the terminal; receiving a mobility management request signal from the terminal, the mobility management request signal being associated with the established one or more connections of the terminal with respect to the one or more PDNs; in response to receiving the mobility management request signal, identifying whether at least one PDN corresponding to at least one of the one or more APNs is in a congested state; and rejecting, if the at least one PDN is in the congested state, the mobility management request, wherein if the terminal is transitioned to an idle state after the one or more connections to the one or more PDNs are established, the mobility management request signal is transmitted by the terminal for transition from the idle state to an active state.
