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. | 03-25-2010 |
| 20100111041 | COMMUNICATION SYSTEM AND DATA TRANSMISSION METHOD THEREOF - 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. | 05-06-2010 |
| 20100112981 | WHITELIST UPDATE METHOD AND APPARATUS FOR USER EQUIPMENT IN MOBILE COMMUNICATION SYSTEM - A method and apparatus for updating a whitelist in a mobile communication system are disclosed. The user equipment can selectively update the whitelist when connecting to the mobile communication system not only through a macro base station but also through a femtocell base station. The apparatus includes a User Equipment (UE), a Mobility Management Entity (MME), a macro base station (eNB), and a femtocell base station (HeNB). | 05-06-2010 |
| 20100115275 | SECURITY SYSTEM AND METHOD FOR WIRELESS COMMUNICATION SYSTEM - A security system processing method of a User Equipment (UE) and a security system for a wireless communication system are provided. The security processing method of the UE includes transmitting a Layer 3 message including a UE security capability to a Mobility Management Entity (MME) and the eNB, receiving a Access Stratum Security Mode Command (AS SMC) including a AS security algorithm selected by the eNB, as a result of verification of the UE security capability and information received from the MME, and a AS Message Authentication Code (MAC), transmitting a AS security mode complete message including the AS SMC to the eNB after verification of integrity of the AS SMC using the AS MAC, and transmitting, when receiving a Non Access Stratum (NAS) SMC including the UE security capability, a NAS security mode complete message to the MME after verification of integrity of the NAS SMC. | 05-06-2010 |
| 20100210267 | REDIRECTION METHOD OF FEMTO CELL AND COMMUNICATION SYSTEM BASED THEREON - 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. | 08-19-2010 |
| 20100210268 | HANDOVER METHOD AND APPARATUS IN A WIRELESS COMMUNICATION SYSTEM INCLUDING FEMTO CELLS - A handover method and apparatus for facilitating a handover of a user equipment to a femto cell in a wireless communication system supporting both the femto and macro cells. When a handover condition is detected, the user equipment acquires identity information of a target femto cell base station from system information transmitted by the target femto cell base station, decides whether to handover to the target femto cell base station, based on the identity information; and transmits a measurement report message including the identity information to a serving base station of the user equipment, when the handover is to be made. | 08-19-2010 |
| 20100234023 | ACCESS CONTROL METHOD USING FEMTO BASE STATION AND COMMUNICATION SYSTEM THEREFOR - A communication system including a femto base station and a method for controlling access of a User Equipment (UE) in the communication system are provided. The method includes receiving a service request message from the UE and transmitting the service request message to a core network entity within a core network, receiving, from the core network, UE information and Local BreakOut (LBO) service information regarding the UE which is used to provide an LBO service to the UE, and providing the LBO service to the UE using the received information. Thus, a core network controls access of the UE so that the UE can directly access an Internet network through the LBO. | 09-16-2010 |
| 20100272050 | METHOD AND APPARATUS FOR MANAGING USER EQUIPMENT HISTORY INFORMATION IN WIRELESS COMMUNICATION NETWORK - A method and an apparatus for managing User Equipment (UE) history information are provided. The method for managing user equipment history information in a wireless communication network includes determining if a recording event occurs when the user equipment enters into an idle mode; recording information about the recording event in idle mode user equipment history information when the recording event occurs; and transmitting the recorded idle mode user equipment history information to a base station when the user equipment accesses the base station. | 10-28-2010 |
| 20100278108 | METHOD AND APPARATUS FOR SUPPORTING LOCAL IP ACCESS IN A FEMTO CELL OF A WIRELESS COMMUNICATION SYSTEM - A method and apparatus for providing a local IP access service to a User Equipment (UE) attached to a femtocell including a Packet Data Network (PDN) gateway function in a wireless communication system. A method includes receiving a service request from a User Equipment (UE), transmitting an initial UE message including information on a local gateway to a Mobility Management Entity (MME), storing bearer information carried in an initial context setup request transmitted by the MME, receiving a Packet Data Network (PDN) connectivity request from the UE, forwarding the PDN connectivity request to the MME, receiving a create session request from the MME, and establishing a radio bearer with the local gateway, the local gateway being co-located with the femtocell. | 11-04-2010 |
