Abstract: The present invention relates to a method and a device for barring access of terminals connected to a base station. A communication method of an Internet protocol multimedia service (IMS) entity, according to one embodiment of the present invention, comprises the steps of: receiving a service request message from a terminal; determining whether to allow an access of a service according to a load status of the IMS and the service requested from the terminal; and transmitting, to the terminal, a connection barring message which includes information for indicating that the access of the terminal is barred, when it is determined to bar the access of the service. According to the one embodiment of the present invention, the IMS can be prevented from being congested due to loads concentrated on IMS entities such as a P-CSCF and the like, and can prevent a situation in which an emergency call or a priority call of a person from a police station or a fire station or the like cannot be received.

Abstract: A method and an apparatus for controlling Short Message Service (SMS) delivery to a User Equipment (UE) over a Packet-Switched (PS) network without involvement of any Circuit Switched (CS) network node are provided. The method includes receiving subscriber information of a terminal from a Home Subscriber Server (HSS), determining whether the MME supports short message delivery over a Packet-Switched (PS) network, and transmitting, when the MME supports the short message delivery over the PS network, a registration request message including information for routing the short message to the MME to the HSS. The SMS delivery method and apparatus is capable of delivering the SMS message to the UE over the PS network without involvement of the CS network nodes, thereby negating the necessity of CS network nodes for supporting SMS service, resulting in reduction of maintenance and management costs.

Abstract: A method and apparatus is provided that improves the quality of voice calls in a mobile communication network. The method of performing transmission/reception of signals in an evolved Node B (eNB) of a mobile communication system includes: receiving a first message including service request information from user equipment (UE); transmitting a second message including the service request information to an Mobility Management Entity (MME); receiving a third message including context information for the UE from the MME; and determining an inactivity timer value for the UE based on the context information. The method and apparatus can maintain, when a voice call is created, connection with calling UE from when the called UE answers the call until the call is set up, thereby preventing part of a caller's voice data from being lost.

Abstract: The present invention relates to a method and an apparatus for transmitting data to user equipment through not only a current base station cell but also a neighboring base station cell via inter-eNB CA in a wireless communication system. A method for transmitting data though carrier aggregation in the wireless communication system, according to the present invention, comprises the steps of: a first base station transreceiving data with a terminal through at least two PDN connections; the first base station transmitting a carrier aggregation request message to a second base station for aggregating carriers, when the first base station determines to carry out inter-eNB carrier aggregation; the first base station receiving a carrier aggregation reply message from the second base station in response to the carrier aggregation request message; the first base station performing an RRC reconfiguration process with the terminal to notify to the terminal of the determination to perform the inter-eNB carrier aggregation; and the first base station transmitting a path change request message to a mobile management entity to correct a data transreceiving path, so that data on at least one PDN connection from among the PDN connections is transreceived through the second base station.
