Abstract: The present disclosure relates to a wireless communication system and to a method for connecting RRC for controlling overloads in the wireless communication system. The method includes the steps of: a mobile signal processing unit transferring an overload control message including preference priority information for overload control to a base station; the base station storing the preference priority information and receiving an RRC connection request message including service information for performing a service from a UE; the base station determining whether the service information is included in the preference priority information when receiving the RRC connection request message; and the base station transmitting an RRC connection allowance message to the UE when the service information is included in the preference priority information. Accordingly, the base station can efficiently control the overload for each service performed in the UE.

Abstract: Provided is a method and apparatus for controlling a charging condition and policy by a first entity, in which information for policy decision information is received from a second entity and an acknowledgement message is transmitted to the second entity. A policy based on the information for policy decision information is determined, the policy is transmitted to a third entity, and an acknowledgement message for the policy is received from the third entity.

Abstract: A method for controlling a charging condition change in a real-time charging system that sends a QoS and charging rule request to be applied to a user terminal from a packet processing node to a real-time charging function server. If a charging condition change is detected, a charging rule change request is sent to a management server and a changed QoS and charging rule is sent, from the management server to the real-time charging function server. The changed QoS and charging rule is sent from the QoS and charging rule management server to the packet processing node. The changed QoS and charging rule are forwarded from the packet processing node to the real-time charging function server and, at the real-time charging function server, quotas for the user terminal are reallocated according to the changed QoS and charging rule.

Abstract: A method for controlling charging condition change in real-time charging system includes sending, if the user terminal requests service, a QoS and charging rule request to be applied to the user terminal from the packet processing node to the real-time charging function server; sending, in response to the QoS and charging rule request, a QoS and charging rule response from the real-time charging function server to the packet processing node; sending, if charging condition change is detected, a charging rule change request from the real-time charging function server to the QoS and charging rule management server; sending, in response to the charging rule change request, a changed QoS and charging rule, from the QoS and charging rule management server to the real-time charging function server; sending the changed QoS and charging rule from the QoS and charging rule management server to the packet processing node; forwarding the changed QoS and charging rule from the packet processing node to the real-time charg
