摘要： Upper level protocol message transmitting method and apparatus are provided based on a new management message to be used in a portable Internet system. When a base station receives the upper level protocol message to be broadcast, it includes the same in the management message and transmits the included message to all the mobile terminals of a cell, and thus, the total number of the transmissions is decreased, thereby increasing a wireless efficiency.

摘要： Disclosed is a handover method in a wireless portable Internet system. When a mobile subscriber station is in a drop state, a ranging request message including an identifier of a previous base station and a string generated by encoding the ranging request message using an authentication key of the previous base station is sent to a target base station. The target base station requests the previous base station to execute handover of the mobile subscriber station using the identifier of the previous base station included in the ranging request message. The previous base station carries out message authentication using the encoded string received from the target base station, and when the authentication is successful, transmits information about the mobile subscriber station that is required for handover to the target base station. Accordingly, a ceaseless service session can be provided even in the drop state.

摘要： Disclosed is a method for constituting a layered cell, which is for constituting a cell in an OFDMA (Orthogonal Frequency Division Multiple Access) mobile communication system. The method includes: (a) dividing L carriers having orthogonality into M sub-channels; (b) dividing the carriers into N groups each having the M sub-channels; (c) grouping the N groups by an arbitrary integer into K classes; and (d) constituting a plurality of layered cells corresponding to the K classes. According to the present invention, the conception of the independent classes is introduced for a plurality of carriers to facilitate the use of the carriers to a system requiring an independent wireless area, allowing design of sectors and cells at a single frequency.

摘要： The present invention relates to a sleep period management method in a mobile broadband wireless access system. In the sleep period management method according to the present invention, a sleep period is increased or decreased when downlink data traffic that has a burst characteristic occurs while a subscriber terminal is operated in a sleep mode. The sleep period management method according to the present invention prevents the terminal from unnecessarily awaking from the sleep mode, so that power saving efficiency can be increased. In addition, when the downlink data traffic that has a burst characteristic occurs while the terminal is operated in the sleep mode, a delay time of the data transmitted to the terminal can be reduced.

摘要： The present invention relates to a handover method of a mobile station in a wireless communication system, and a base station and a mobile station for the same. A list of neighboring base stations that can accept a handover of a mobile station is shared by the mobile station and a serving base station before the mobile station performs the handover so as to reduce handover delay time in a high speed environment through a simplified control message exchange process. In addition, the active base station set managed by the mobile station and the serving base station can be managed with consideration of radio signal quality and resource state of each of the neighboring base stations included in the active base station set, and thus when the mobile station attempts a network re-entry process to a target base station that is not ready for the handover of the mobile station due to a loss of a handover control message, a handover failure due to a lack of radio resources can be prevented, thereby increasing a handover success rate.
摘要翻译：本发明涉及移动台在无线通信系统中的切换方法，以及用于其的基站和移动台。可以接受移动台的切换的相邻基站的列表在移动台执行切换之前由移动台和服务基站共享，以便通过简化的控制消息来减少高速环境中的切换延迟时间交流过程。此外，考虑到包括在有源基站组中的每个相邻基站的无线电信号质量和资源状态，可以管理由移动台和服务基站管理的有源基站集合，因此当移动台由于丢失切换控制消息，站尝试对未准备好进行移动台切换的目标基站的网络重入进程，可以防止由于缺乏无线电资源而导致的切换失败，从而增加切换成功率。
