摘要
文中提出了一种适用于蜂窝通信网的分布式无线信道分配方法。当网络部署环境中出现干扰后,终端用户通过控制信道,发送反馈信息至基站;基站接收到反馈信息后,对可用信道进行扫频,利用广播帧通知受干扰的终端用户可用信道信息;然后终端用户收到基站发送的广播帧后,根据优先级机制,选择新的信道重新建立与基站的通信,当蜂窝通信网中终端用户受外部干扰而信道中断后,该方法可减少终端用户和基站之间信令的开销。
A novel distributed wireless channel allocation method for cellular networks is proposed in this paper. In case that interference co-exists in the network deployment environment,user terminals are capable of sending feedback information to a base station over control channel,and then the base station informs the interfered users the available channels by broadcast frame. By using a priority mechanism,user terminals can select its suitable channels and re-set up the connections with the base station. The numerical results show that the proposed method can reduce the signaling overhead between user terminal and base station.
