    Abstract: Provided is a method of sending and receiving signals for a user equipment (UE) in a mobile communication system. The method may include: receiving a service reject message from a Mobility Management Entity (MME) under congestion; sending a message containing at least one piece of information determined based on the service reject message to a Mobile Switching Center (MSC); receiving a message containing camping cell information from a base station (eNB); and camping on a cell indicated by the camping cell information. In one embodiment, when an MM back-off timer is applied to the UE utilizing CSFB (or SMS over SGs) at the time of network congestion, the MSC or 2G/3G RAN node is notified that the MM back-off timer is running in the UE, so that the UE may camp not on an LTE cell but on a 2G/3G cell after CS service reception. Hence, it is possible to prevent call drops for MT services that may be caused by UE location registration failure due to the MM back-off timer.

    Abstract: According to an embodiment, a network access method of a user equipment (UE) in a communication system comprises the steps of: receiving information including an access order from a configuration server; storing the received information; and transmitting an access request to the network according to an access method determined on the basis of the stored information. According to another embodiment, a UE for accessing a wireless communication system comprises: a transceiving unit which receives information including an access order from a configuration server; and a control unit for storing the received information and controlling the transceiving unit to transmit an access request to the network according to an access method determined on the basis of the stored information. According to an embodiment of the present disclosure, when a UE for supporting a PS network and a CS network accesses a network, the UE receives a configuration of each domain registration method in advance, and thus can more easily access each network. In addition, according to another embodiment of the present disclosure, message transmission can be more easily achieved between a system in which a long SMS message can be transmitted and a system in which a SMS message of conventional-length is transmitted. Furthermore, according to another embodiment of the present disclosure, when a UE, which has performed a CS fallback, returns to a 4G network due to the end of a CS service, the UE can be prevented from returning to another provider network since the UE has existing return information.

    Abstract: The present invention relates to a method for controlling system overload in a wireless communication system. The method comprises: a first step in which a mobility management entity (MME) that has received a tracking region update request message from a first terminal transmits a location update request message to a home subscriber server (HSS); a second step in which, if the HSS has determined that a system overload has occurred, the HSS sets MME-backoff time for preventing the transmission of a request message to the HSS, and transmits a location update rejection message including said MME-backoff time to the MME; and a third step in which the MME drives a backoff timer corresponding to said MME-backoff time and rejects a TAU update request message from a terminal received prior to the completion of the driving of the backoff timer.

    Abstract: Provided are a method and apparatus for processing packets. A method for processing packets in a base station (ENB) may include: obtaining information on a rule for dealing with a packet according to supplementary information contained in the header of the packet; receiving a packet; extracting supplementary information from the header of the received packet; and processing the received packet on the basis of the obtained rule information and extracted supplementary information. Hence, the base station may adequately perform packet control operations in accordance with the state thereof.
