An access admission control method and system for and SAE/LTE system is provided for determining whether to accept or reject an access of a User Equipment (UE) to a Home evolved Node B (HeNB) based on the subscriber information of the UE. In an access admission control method according to the present invention, a HeNB or HeNB Gateway (HGW) transmits, when an access request message is received from a UE, the access request message to a Mobility Management Entity (MME) together with a CSG ID of the HeNB, and the MME determines, whether to accept or reject the access of the UE to the HeNB based on whether the CSG ID is contained in a white list associated with the UE.

Access admission control method and system for mobile communication system

A remote control method and an apparatus for home appliances, wherein a remote controller performs situation recognition using sensors and automatically controls home appliances without a control message from a portable device when communication with the portable device is not possible, are provided. The remote control method is designed for a remote controller managing home appliances installed in a home. The remote control method includes receiving a remote control request from a portable device capable of remotely controlling one or more home appliances, performing, upon reception of the remote control request, situation recognition with respect to the home appliances, and controlling operations of the home appliances based on situation recognition results.

Remote control method and apparatus for home appliances

A wireless communication system for performing a handover to a femto base station is provided. The system includes user equipment, a femto subscriber information storage, a core network entity or a macro base station or a serving base station. The femto subscriber information storage stores a list of femto base stations that allows the access of user equipment, i.e., an accessible list. The core network entity or the macro base station receives and stores the accessible list. When any of the user equipment requests a handover toward a femto base station as a target base station, and the target base station is included in the accessible list stored, the core network entity or the macro base station requests a handover toward the target base station. A method for performing a handover to the core network entity and the macro base station is also provided.

Communication system for handover to femto base station and method for the same

A local breakout session establishment method and apparatus in an Evolved Packet System (EPS) is provided for an HeNB to efficiently route local IP packets. A local breakout service method for a wireless communication system including a macro evolved Node B (eNB) and a Home eNB (HeNB) having a Packet Data Network (PDN) gateway (PGW) and a serving gateway (SGW) includes selecting, at a Mobility Management Entity (MME), the PGW of the HeNB and transmitting a Create Default Bearer Request message to the HeNB in response to a local breakout service request message including a local breakout Access Point Name (APN); assigning, at the HeNB, an IP address to a user equipment transmitted the local breakout service request message and transmitting a Create Default Bearer Response message including a Tunnel Endpoint Identifier (TEID) to the MME; transmitting a Bearer Setup Request message including the TEID from the MME to the HeNB; and configuring, at the HeNB, a radio bearer with the user equipment and routing data transmitted by the user equipment through the radio bearer to an Internet Protocol (IP) network by means of the internal PGW.

Local breakout session establishment method and apparatus in wireless communication system

A communication system and data transmission method thereof are provided. The method includes adding an end marker to the end of source data and transmitting the source data and the end marker for a Packet data network GateWay (PGW) to a source evolved Node B (eNB) if a handover is carried out from the source eNB to a target eNB while the PGW is transmitting the source data to the source eNB, forwarding the source data and the end marker from the source eNB to the target eNB, transmitting target data immediately following the source data from the PGW to the target eNB, and transmitting the source data and the target data, which is classified into the source data by the end marker and immediately follows the end of the source data, from the target eNB to user equipment.

Communication system and data transmission method thereof

A redirection method of a femto cell is provided together with a communication system based thereon. A serving gateway, connected with a specific femto cell, or an additional server determines whether there is a need for a redirection of the femto cell by using a load condition of the serving gateway or a target gateway. If the redirection is determined, the femto cell receives redirection instructions from the serving gateway to the target gateway and then the redirection is performed. Since the femto cell is redirected from the overloaded femto gateway to another femto gateway, the femto cell can continuously provide a communication service to user terminals.

Redirection method of femto cell and communication system based thereon

The present invention relates to a method and system for the management of the mobility, the management of an idle mode, the registration management (management of attachment and detachment), and the location management (management of tracking area) of a terminal by using a non-access stratum (i.e., network stratum, hereinafter referred to as 'NAS') in a mobile telecommunication network. To this end, the method for the management of mobility, the management of an idle mode, the registration management, and the location management of a terminal by using a NAS protocol, i.e., messages, according to an embodiment of the present invention, includes a terminal (hereinafter, referred to as 'UE') and a mobility management entity (hereinafter, referred to as &#x201c;MME&#x201d;), and addresses to a method for efficiently processing security protected NAS messages if received messages are security protected NAS messages, in a case of sending or receiving messages serving as EMM (EPS Mobility Management) messages, i.e., mobility management messages, in a network such as an EPS (Evolved Packet System) of 3GPP, when the terminal performs handover in an active mode, performs location management in an idle mode, and registers to a network, thereby achieving improved efficiency in the mobility management, the position management, and the registration management of a terminal.

Security protected non-access stratum protocol operation supporting method in a mobile telecommunication system

A method and communication system for assigning the control authorization for controlling functions of a device from a terminal to another terminal in a communication system is provided. Through the method, it is possible to simplify the authentication process of a terminal having the communication function based on the short messaging service, and to reduce the security information size generated in the authentication process.
