Abstract: Disclosed herein are a method for balancing the quality of a wireless communication channel wherein the quality of the wireless communication channel can be more accurately estimated and adjusted on the basis of the combination of observation results of the number of data frames failed to be transmitted in the past and a received signal strength (RSS), and reliability of data transmission over the channel can thus be increased, and a wireless communication apparatus using the same. The method includes collecting information about whether data frames have been successfully transmitted and information about RSSs of the wireless communication channel, acquiring the number of data frames failed to be transmitted and an average RSS in a predetermined observation period using the collected information, comparing the acquired transmission-failed data frame number with a predetermined threshold value and the acquired average RSS with a predetermined reference RSS, respectively, and estimating the quality of the wireless communication channel and quality degradation factors in detail by performing an AND operation with respect to the comparison results. Therefore, it is possible to stably adjust the channel quality.

CONSTITUTION: An OLT system(20) is comprised of a service port function unit(21), a control function unit(22), an OLT traffic distribution function unit(23), a logical link identifier DB(24), an OLT OAM(Operations, Administration and Maintenance) function unit(26), and an OLT management DB. The service port function unit(21) processes traffic transmission/reception with a backbone network. The control function unit(22) controls traffic transmission/reception and transport channel allocation in the OLT system(20). The OLT traffic distribution function unit(23), if a traffic is received from an external backbone network or an internal ONU(40), confirms the type and destination subscriber of the traffic and judges to which ONU the traffic is to be transmitted, based on the logical link identifier DB(24). The OLT OAM function unit(26), managing the network state and performance in the whole system, requests the OAM function unit of each ONU(40) to transmit management information, receives it, and stores it in the OLT management DB.

Abstract: PURPOSE: A device and a method for processing a distributed object using a priority succession technique are provided to change the priority of a server method according to a request of a client by succeeding the priority requested from the client to the priority of the server method. CONSTITUTION: A priority assigner assigns the priority to the method when the client(101) calls the method of a server object. An IDL(Interface Description Language) stub(102) and a middleware core(103) transfer the called method and the assigned priority to a server(107). A priority processor(104) executes the server object depending on the priority assigned from the client by converting the priority transferred from the IDL stub and the middleware core into a system priority, generating a thread having the system priority, and mapping the generated thread to the called method.

Abstract: PURPOSE: A method and apparatus for dynamically allocating bands by service class are provided to ensure service quality by using ethernet frames for uplink/downlink transmission between ONU(Optical Network Unit) and OLT(Optical Line Terminator) and previously reserving an amount of requested band of each service class of the ONU. CONSTITUTION: When an MPCP(Multi-Point Control Protocol) allocator(210) receives an uplink report control message from a control layer(220), a class queue state calculator(212) discriminates ONUs and acquires length information of queues by class in the ONUs. When queue state information of every ONU is collected, a permission generator(211) generates bands by ONU and bands by service of the ONUs, and transmits downlink band allocation(GATE) control messages by ONU. An MPCP requester(230) receives the downlink band allocation(GATE) control message from an MAC control layer(240). A class buffer counter(232) counts length of buffers of each class of the ONUs, and a request generator(231) generates length information of buffers by class in the ONUs. The generated information is transmitted as an uplink report control message to the MAC control layer(240).
