    • The present invention relates to a scheduling apparatus and a method thereof in an HPi system. A scheduling algorithm is applied appropriate to a characteristic of each multimedia service (e.g., real-time service, non real-time service, best-effort service, etc.) and a transmission order of the IP packets transmitted from a network is determined such that a transmit wait queue is generated. Radio resource allocation is performed in accordance with the order of the data items queued in the transmit wait queue, the size of transmittable data is determined such that a PDU is generated. In addition, frame data formed of bursts of PDUs is generated and transmitted to a physical layer. Therefore, a scheduling algorithm can be applied appropriate to characteristics of each multimedia service. In addition, packet scheduling is performed in two steps in order to schedule traffic corresponding to radio frames such that packets can be efficiently processed.
    • 本发明涉及一种HPi系统中的调度装置及其方法。 适用于每个多媒体业务的特性(例如,实时业务,非实时业务,尽力服务等)的调度算法被确定为从网络发送的IP分组的传输顺序, 生成发送等待队列。 根据发送等待队列中排队的数据项的顺序执行无线资源分配,确定可发送数据的大小,使得生成PDU。 另外,由突发的PDU形成的帧数据被生成并发送到物理层。 因此,可以适用于每个多媒体业务的特征的调度算法。 另外,分两个步骤进行分组调度,以便调度与无线帧相对应的业务,从而可以有效地处理分组。

    • The present invention relates to a method for searching and releasing an abnormal subscriber station in a wireless portable Internet system, and an apparatus using the same. The apparatus searches for an abnormal group including abnormal subscriber stations based on a ranging code provided in a periodic ranging process, and searches for an abnormal subscriber station by transmitting a connection maintenance message to subscriber stations included in the abnormal group so as to check an operation status of the respective subscriber stations. In addition, the apparatus releases a connection of an abnormal subscriber station. Therefore, waste of radio resources allocated to the abnormal subscriber station can be prevented, thereby achieving efficient resource management. Further, a secondary search process is performed only for subscriber stations included in an abnormal group, thereby preventing a system load from occurring when searching for an abnormal subscriber station.
    • 本发明涉及一种在无线便携式互联网系统中搜索和释放异常用户站的方法及其使用方法。 该装置基于在周期性测距处理中提供的测距码,搜索包括异常用户站的异常组,并通过向包括在异常组中的用户站发送连接维护消息来搜索异常用户站,以便检查操作 各个用户站的状态。 此外,该装置释放异常用户台的连接。 因此,可以防止分配给异常用户站的无线资源的浪费,从而实现有效的资源管理。 此外,仅对包括在异常组中的用户站执行辅助搜索处理,从而防止在搜索异常用户站时发生系统负载。
