摘要： Various examples of the present disclosure describe a random access method and device in a CR system. The method includes: generating, by a base station device, a spectrum handover command, wherein the spectrum handover command comprises random access backoff time parameter information; and sending, by the base station device, the spectrum handover command to a user equipment in a cell to instruct the UE to initiate, during a spectrum handover procedure, a random access procedure using the random access backoff time parameter information. According to the various examples of the present disclosure, the random access backoff time parameter information is carried in the spectrum handover command, so that a random access conflict is suppressed during the spectrum handover procedure of the CR system. A large number of UEs that intensively perform random access on a target working frequency are pre-dispersed in time. As such, the delay and the failure probability of the random access on the target working frequency during the spectrum handover procedure are reduced, and thus the failure probability of the spectrum handover and the service interruption time are reduced, so that the user experience of the CR system is improved.
摘要翻译：本公开的各种示例描述了CR系统中的随机访问方法和设备。该方法包括：由基站装置生成频谱切换命令，其中频谱切换命令包括随机接入退避时间参数信息; 以及由所述基站装置向所述小区中的用户设备发送所述频谱切换命令，以指示所述UE在频谱切换过程期间使用所述随机接入退避时间参数信息来发起随机接入过程。根据本公开的各种示例，在频谱切换命令中携带随机接入退避时间参数信息，从而在CR系统的频谱切换过程期间抑制随机接入冲突。在目标工作频率上集中执行随机访问的大量UE预先分散在时间上。因此，在频谱切换过程中随机接入对目标工作频率的延迟和故障概率降低，从而降低了频谱切换和业务中断时间的故障概率，使得用户体验 CR系统得到改进。
