    Abstract: PURPOSE: A method for controlling the transmission power of a femto base station and a device thereof are provided to calculate the size of interference received from adjacent femto or macro base stations using a femto terminal. CONSTITUTION: An interference predicting part(620) predicts femto base station interference which is applied from an adjacent femto base station to a terminal and macro base station interference which is applied from a macro base station to the terminal. A power controlling part(640) determines the transmission power of downlink signals based on the femto and macro base station interference. A transmitting part(650) transmits the downlink signals based on the transmission power. The interference from the femto base station is predicted based on a distance between a serving femto base station and the adjacent femto base station and the transmission power of the adjacent femto base station. The interference from the macro base station is predicted based on a distance between a serving femto base station and the macro base station and the transmission power of the macro base station.

    Abstract: PURPOSE: An admission control method of a hybrid femto cell is provided to effectively control interference between MS terminals by utilizing the acceptance control method of a hybrid femto cell. CONSTITUTION: When an MS(Mobile Station) terminal is not belong to CSG(Closed Subscriber Group), a core network determines speed information for the MS terminal(S410, S430). When the speed information is not included, the core network gives the lowest set probability value to the MS terminal(S450). When the speed information is included, the core network gives a probability value in a range between the lowest set probability value and the highest probability value to the MS terminal(S440). The core network finally determines acceptance for a portable terminal(S460).

    Abstract: PURPOSE: A handover control method and an apparatus thereof are provided to compare a link latency of an X2 interface and a link latency of an S1 interface and to select an interface for processing the handover. CONSTITUTION: A determining unit(610) decides whether a direct interface is exist or not, which directly interlinks a source base station and at a base station. In case the determining unit decides that the direct interface exists, a comparison unit(620) compares the link latency of the direct interface with a link latency of an indirect interface which indirectly interlinks the source base station and target base station. A selecting unit(630) directly selects an interface for proceeding the hand over between the direct interface or the indirect interface based on the comparison result of the comparison unit.

    Abstract: A method for managing a bandwidth of a terminal device in a portable Internet system is provided to determine a bandwidth request method by reflecting current state of the terminal device, thereby performing efficient bandwidth management. A method for managing a bandwidth comprises the following steps of: calculating the currently-necessary bandwidth of a terminal device(S400); determining whether a traffic CID(Connector Identifier) is generated or not(S402); if so, determining whether IP(Internet Protocol) assignment is performed in the terminal device(S404); if so, checking a transmission frequency of uplink data and determining whether the checked transmission frequency is higher than a preset reference threshold value(S406); and if so, attempting a bandwidth request through an ensured access method(S408).

    Abstract: PURPOSE: A GPRS(General Packet Radio Service) system having a multi-GGSN(Gateway GPRS Supporting Node) and a method for selecting a GGSN are provided to increase system availability through dispersion and flexibly cope with traffic increase and decrease by processing an external network with many nodes. CONSTITUTION: A GPRS system having a multi-GGSN comprises an SGSN(Serving GPRS Supporting Node)(201), a GPRS network(202), a multi-GGSN part(210), a FA(Foreign Agent)(203), an operator network(204), a DNS(Domain Name System)(205), a DHCP(Dynamic Host Configuration Protocol)(206), an edge router(207), and an external network(208). The multi-GGSN part(210) consists of many sub GGSNs(210-1-210-n), and the sub GGSNs(210-1-210-n) are the same systems executing identical functions. The sub GGSNs(210-1-210-n) work independently in a notion of load distribution. If one among the sub GGSNs(210-1-210-n) is down, another node takes a share in the node's duties.
