Abstract: Provide is a device and a method for registering the device supporting home networking, by a server. The method includes receiving a registration request for the device from a user and determining whether the device was registered by the user. If the device has been registered, a re-registration authentication code is obtained based on an initial authentication code of the device, and registration of the device is mapped to the re-registration authentication code.

Abstract: To solve the problems that may occur due to the leakage of user account information, the present disclosure may manage the security using the device token that is used independently of that of the server, that is generated by a home device, and that can be used for device authentication when a smart phone controls home appliances. With the use of the device token, the present disclosure may solve the problems that the status information of home appliances is exposed by another person or the home appliances are controlled by another person, even though the user account information is leaked.

Abstract: A method and apparatus for controlling devices for a smart home service are provided. The method includes grouping devices to receive at least one command simultaneously from among devices registered to the smart home service into a group for one mode, generating mode configuration information for each mode including grouped devices for the mode and at least one command for the mode, transmitting the mode configuration information for each mode to the registered devices, selecting one of each mode for which the mode configuration information has been generated, and transmitting a mode activation request for activating the selected mode to the registered devices.

Abstract: 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.

Abstract: A method and apparatus for performing a L3 handover between CNs in a packet-switched network are provided. When a UE moves from an old RAN to a new RAN, the UE sends a measurement report message including cell information to the old RAN. The old or new RAN determines whether to perform a L3 handover. If the L3 handover is required, a tunnel is established between the new RAN and a new CN. The UE performs a handover from the old RAN to the new RAN, without establishing a tunnel between the new RAN and an old CN. Upon detection of the movement of the UE, the new RAN sends a L2 handover complete message to the old RAN. After moving to the new RAN, the UE acquires a new IP address, performs the L3 handover, and communicates with the new CN through the new RAN.

Abstract: 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.

Abstract: A method and apparatus is provided for communication between a first terminal capable of using both a Circuit Switched (CS) call and an Internet Protocol Multimedia Subsystem (IMS) session, and a second terminal capable of using the IMS session, in a communication system supporting a Combined CS call and IMS session (CSI service). If the second terminal sends a Session Initiation Protocol (SIP) request (INVITE) message to originate a voice service or a multimedia service including the voice service with the first terminal, a CSI Application Server (AS) of an IMS domain managing the first terminal separates a voice service-related component included in the request message from a multimedia service-related component, and generates and sends first and second request messages to the first terminal.

Abstract: A method for controlling access between home devices and servers in a home network system is provided. The method includes determining whether first access of the home devices to each of the servers and second access of the servers to each of the home devices is restricted, and controlling the first access and second access based on respective access rights established according to the determination.

Abstract: 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.

Abstract: A method and system in which upon occurrence of a P-CSCF failure, a network sends an IMS reregistration request message to a UE. An S-CSCF or an AS monitors a P-CSCF to detect occurrence of a failure in the P-CSCF. Upon detecting the occurrence of a P-CSCF failure, the S-CSCF or the AS sends a request message for IMS reregistration to the UEs being served by the failed P-CSCF. In this manner, the UE can continuously receive the service even though a failure occurs in the P-CSCF.
