在一个实施例中，如图13所示，定时信息确定方法的步骤还包括：
步骤120、获取系统消息，对系统消息进行解析确定频率偏差。
系统消息是指计算机设备所处的直放站系统的相关消息。计算机设备在获取到系统消息后，对其进行解析能够确定频率偏差，即直放站系统工作时存在的频率偏差。本实施例对计算机设备对系统消息进行解析的具体方法不作限制，只要能够得到频率偏差即可。
步骤121、根据频率偏差对直放站系统的载波频率进行补偿。
计算机设备在获取频率偏差信息后，使用该频率偏差对直放站系统的载波频率进行补偿。可选地，计算机设备将直放站系统的载波频率与频率偏差相加，或与频率偏差相减，实现对直放站系统的载波频率的补偿。
在本实施例中，使用确定的频率偏差对直放站系统的载波频率进行补偿，可以提高直放站系统接收信源信号的准确性，即计算机设备接收信源信号的准确性，从而能够提高确定的同步信号的准确性，进而能够提高确定的定时信息的准确性。
在一个实施例中，定时信息确定方法还包括：获取广播信息和系统消息，并对广播信息和系统消息进行解析，得到时隙配比、宏站运营商的公共陆地移动网络、绝对秒时间授时等。其中，系统消息是通过下行共享信道获取的。根据时隙配比和宏站运营商的公共陆地移动网络可以调整直放站系统中的功放等射频器件的开启和关闭时间；根据绝对秒时间可以获取当时的真实时间，以便于进行日志记录。

步骤133、若信号类型不是标准时钟源信号，则判断信号类型是否是数字信号；
步骤134、若信号类型是数字信号，则获取信源信号中的多个频段信号，并根据多个 频段信号确定同步信号；
步骤135、若信号类型不是数字信号，则判断信号类型是否是模拟信号；
步骤136、若信号类型是模拟信号，则对信源信号进行模数转换，得到转换后的数字信号，并获取转换后的数字信号中的多个频段信号；
步骤137、根据多个频段信号确定同步信号；
