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。

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： Disclosed is a method in which a base station that supports multiple carriers transmits a paging message. The base station determines a first time for transmitting information associated with a multicast broadcast service (MBS), and transmits the information associated with an MBS at the first time via a first carrier. The base station determines a second time for transmitting a paging message to a mobile station, determines a second carrier for transmitting the paging message to the mobile station, and transmits the paging message at the second time via the second carrier. The second time is different from the first time.

摘要： The present invention relates to encryption and decryption apparatuses in a wireless portable Internet system, and a method thereof. In the wireless portable Internet system, a subscriber station and a base station share an encryption during key distribution, and a message is encrypted with the encryption key and transmitted. In this case, a first initial vector is generated for encryption based on information shared by the subscriber station and the base station in a wireless channel, and the message is encrypted with the first initial vector and the encryption key and is then transmitted. In addition, a second initial vector for decryption is generated based on information shared by the subscriber station and the base station in the wireless channel, and the encrypted message is decrypted with the second initial vecrtor and the encryption key. Herein, the first initial vector corresponds to the second initial vector.
