Abstract: A method for selecting an RS(Relay Station) in a mobile communication system is provided to measure the signal quality of a signal transmitted from a UE(User Equipment) for an uplink slot time and select the RS on the basis of signal quality information included into an SS-SIG-REP message, thereby selecting the RS capable of providing the optimal service to each user out of plural RSs. A method for selecting a RS in a mobile communication system comprises the following steps of: performing network initialization when a UE enter a network initially(S100); transmitting a UL-MAP(Uplink-MAP) to the UE(S110); analyzing the UL-MAP allocated to the UE from a BS(Base Station) to recognize an uplink slot time(S120); measuring the signal quality of a signal transmitted from the UE for the uplink slot time and transmitting an SS-SIG-REP(Subscriber Station-Signal-Report) message including information about the measure signal quality to an upper RS collectively(S130); receiving the SS-SIG-REP message in the BS(S140); and selecting the RS for transceiving signals with the UE on the basis of the generated SS-SIG-REP message(S150).

Abstract: An apparatus and a method for supporting a high speed communication service using a UWB(Ultra-Wide Band) technique are provided to apply Bluetooth technique to various application devices to thus extend services up to video-centered services as well as audio-centered services. A PAL(Protocol Application Layer) management entity(110) splits command data received from an upper layer, a Bluetooth region, into local state and remote state commands to perform event processing, and processes command data received from a lower layer, a UWB region, to transmit the same to the upper layer. An FCSL(Frame Convergence Service Layer) entity(120) generates a PAL packet having the command data received from the upper layer in UWB data and transmits the generated PAL packet to the lower layer. The FCSL entity interprets a data type received from the lower layer, and if the received data type is command data, the FCSL entity transmits the received command data to the PAL management entity. The upper layer and the lower layer are connected to support a high speed communication service.

Abstract: A clock time synchronization method for a wireless 1394 heterogeneous network is provided to assure isochronous data transmission between a transmission node and a reception node, by transferring synchronization time information considering arrival time of a packet to the reception node using another IEEE1394 protocol through a wireless network from the transmission node using one IEEE1394 protocol. In a clock time synchronization method for a wireless 1394 heterogeneous network, a cycle master(21) inserts present time into a cycle start packet and then transmits the cycle start packet to a transceiver bridge(12). The transmitter bridge performs synchronization using the time inserted into the cycle start packet and transmission time of the cycle start packet, and generates a first synchronization time to be inserted into the cycle start packet(202), and then transmits the cycle start packet to a wireless 1394 coordinator(13). The wireless 1394 coordinator performs synchronization using the first synchronization time on the cycle start time, and obtains a second synchronization time by considering arrival time to a wire IEEE1394 network to the first synchronization time(204). The wireless 1394 coordinator generates information element structure using the second synchronization time and then inserts the information element structure into a beacon frame, and transmits the beacon frame to the receiver bridge on the wire IEEE1394 network. The receiver bridge performs synchronization using the second synchronization time inserted into the cycle start packet, and obtains a third synchronization time by considering arrival time to a reception node(16) to the second synchronization time(207). The receiver bridge synchronizes the heterogeneous network by transferring the third synchronization time to the reception node.

Abstract: A method for effectively using power resource in a wireless mesh network is disclosed to select and change a level of a power saving mode according to terminal and network situations to increase the duration of the network's existence as well as improve the power consumption of each mesh terminal. After active mesh terminals that are to perform a data relay function and super-saving mesh terminals that are not to perform the data relay function are selected in consideration of a network topology at certain periods, the level of a power saving mode of the mesh terminals selected as the super-saving mesh terminals is higher than that of the mesh terminals selected as the active mesh terminals. And then, a routing path in a tree form is formed along the mesh terminals selected as the active mesh terminals to transmit data.

Abstract: A method and an apparatus for implementing an IEEE 1394 bridge are provided to easily configure an IEEE 1394 network through a bridge by enabling a network configuration and management message forwarding function to be performed between portals in an IEEE 1394 network. An IEEE 1394 bridge comprises two portals(110,120), two packet distributors(114,124), and two co-portal interfaces(115,125). The portals create and process network configuration/management messages if the configuration of an IEEE 1394 network is required. The packet distributors, respectively connected to the portals, classify provided packets according to the transmission/reception directions of the packets and packet data and deliver the classified packets to their respective portals. The co-portal interfaces, respectively connected to the packet distributors, receive the classified packets and deliver them to a co-portal. Also the co-portal interfaces receive packets from the co-portal and forward them to their respective packet distributors.

Abstract: A method for creating a route map in a wireless 1394 bridge network is provided to minimize the frequency of retransmission, the transfer delay time of packets, and system loads by creating a new route map with modified information in configuring a new network according to the addition or deletion of bridges and reducing the volume of data to be transmitted in a radio section. A control part stores the present route map information(801). In configuring a new network based on the addition or deletion of bridges, the control part collects modified bus information(802). The control part confirms whether the volume of collected bus information exceeds a critical value(803). If the volume of collected bus information exceeds the critical value, the control part creates a route map containing every bus information(804). However, in case the volume of collected bus information does not exceed the critical value, the control part creates a route map containing modified bus information(805).
