    • To provide a channel selection method of a wireless communication system which enables a wireless station to select a wireless channel dynamically even when there are but an insufficient number of wireless channels, a channel selection method of selecting a wireless channel from a plurality of wireless channels prepared for the wireless communication system comprises: a channel search step (202) of checking whether any one of the plurality of wireless channels is left unused by other wireless stations of the wireless communication system or not; a sharing channel selection step (207) of selecting a wireless channel to be shared from wireless channels under use of the other wireless stations, said sharing channel selection step being performed when every of the plurality of wireless channels is found (205) to be under use of one of the other wireless stations at the channel search step; and a link establishment step of establishing the wireless link by sharing the wireless channel selected at the sharing channel selection step.
    • 为了提供无线通信系统的信道选择方法,其使得无线站能动态地选择无线信道,即使当存在但不足数量的无线信道时,也可以选择从多个无线信道中选择无线信道的信道选择方法 对于所述无线通信系统,包括:检测所述多个无线信道中的任一个是否被所述无线通信系统的其他无线站不被使用的信道搜索步骤(202) 共享信道选择步骤(207),用于从其他无线站使用的无线信道中选择要共享的无线信道,所述共享信道选择步骤是在多个无线信道中的每一个被发现(205)被执行时执行的 在频道搜索步骤中使用其他无线电台之一; 以及链路建立步骤,通过共享在共享频道选择步骤中选择的无线频道来建立无线链路。

    • A mobile communication system includes base stations, mobile stations, first and second channel assigning section, and a channel ratio changing section. The base stations are installed in correspondence with cells constituting a service area. Each mobile station performs communication with the base station through one channel selected from the channels classified into first and second groups. The first channel assigning section uses a channel segregation scheme of controlling the priority of a channel set in each of the base stations on the basis of carrier to interference ratios of a channel belonging to the first group, measured at both the mobile station and the base station, and selects/assigns one idle channel in the first group on the basis of the controlled priority. The second channel assigning section uses an ARP scheme of selecting/assigning one idle channel in the second group according to a priority common to all the cells on the basis of carrier to interference ratios of a channel belonging to the second group, measured at both the mobile station and the base station. The channel ratio changing section changes the ratio of the number of channels belonging to the first group to that of channels belonging to the second group on the basis of channel assignment results.
    • 移动通信系统包括基站,移动站,第一和第二信道分配部分以及信道比例变化部分。 基站与构成服务区的小区相对应地安装。 每个移动台通过从分为第一和第二组的信道中选择的一个信道来执行与基站的通信。 第一信道分配部分使用信道分离方案,其基于在移动台和基站测量的属于第一组的信道的载波干扰比来控制每个基站中设置的信道的优先级 并且基于受控优先级来选择/分配第一组中的一个空闲信道。 第二信道分配部分使用根据在属于第二组的信道的属于第二组的信道的载波干扰比,根据所有小区共有的优先级,在第二组中选择/分配一个空闲信道的ARP方案 移动台和基站。 信道比率改变部分基于信道分配结果改变属于第一组的信道数量与属于第二组的信道的数量的比率。
