摘要： Disclosed herein is a system and method for coupling communication terminals. In a communication method performed by a terminal coupler according to the present invention, sequence numbers are sequentially assigned to data packets received from a terminal end device. The data packets with the sequence numbers assigned thereto are individually transferred to a plurality of communication terminals belonging to a same group in conformity with preset scheduling policies. Data packets, received from the plurality of communication terminals belonging to the same group, are reordered by sequence numbers, and the reordered data packets are transferred to the terminal end device.

摘要： 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.

摘要： 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.

摘要： The present invention relates to a mobile communication system, and more particularly, to a repeater and a ranging method using the repeater. In the mobile communication system including the repeater, a ranging operation is performed so that data are transmitted to a base station regardless of whether a mobile terminal is within a repeater area. Accordingly, it is determined whether a ranging code received through a ranging flag is directly received from the mobile terminal or if it is received through the repeater. When the ranging code is transmitted to the base station through the repeater, the ranging operation of the mobile terminal is performed.
