第一种方式： 星卡资源共享设备接收星卡上报的表示是否故障的状态信 息， 根据星卡上报的状态信息， 判断星卡是否故障。
第二种方式： 星卡资源共享设备上配有检测电路， 利用检测电路检测星卡 是否故障。
步骤 306、 根据上述步骤的判断结果， 通过告警指示接口向基站设备二发 送表示星卡是否故障的告警指示信息，基站设备二根据告警指示信息确定是否 利用所接收的来自星卡的数据信号和时钟源信号。 其中， 步骤 304、 步骤 305 和步骤 306是可选步骤。
为了适用于松耦合应用场景， 如图 2B所示， 基站设备一和基站设备二都 需要配置独立的天馈系统和星卡，和星卡资源共享接口设备，基站设备二上的 星卡资源共享接口设备接收来自基站设备一的数据信号、 时钟源信号、在位指 示信息和表示星卡是否故障的告警指示信息，其根据来自基站设备一的表示星 卡是否故障的告警指示信息，确定基站设备二是否利用基站设备一上星卡的数 据信号和时钟源信号。 同样的，基站设备一上的星卡资源共享接口设备可以通 过数据接口接收来自基站设备二上星卡的数据信号，通过时钟接口接收来自基 站设备二上星卡的时钟源信号，通过在位指示接口接收表示基站设备二上是否 有星卡的在位指示信号，通过告警指示接口接收表示基站设备二上星卡是否故 障的告警指示信号。
一般情况下，基站设备一和基站设备二都使用自己的星卡的数据信号和时 钟源信号 ,在自己星卡出现故障时 ,会使用对方星卡的数据信号和时钟源信号 , 具体为：基站设备一上的星卡资源共享接口设备根据来自基站设备二的告警指 示信号， 判断基站设备二上的星卡是否故障，如果基站设备二上的星卡没有故 障，则向基站设备一发送通过数据接口接收的来自基站设备二上星卡的数据信 号， 和通过时钟接口接收的来自基站设备二上星卡的时钟源信号。 其中，基站设备一接收来自基站设备二上星卡的数据信号的数据接口可以 与步骤 303采用相同的数据串口， 此时， 该数据串口为双向的； 也可以另外采 用一个数据接口接收来自基站设备二上星卡的数据信号， 不影响本发明的实 现。 同理，基站设备一接收来自基站设备二上星卡的时钟源信号的时钟接口可 以与步骤 303中的相同，此时该接口为双向接口，也可以另外采用一个时钟接 口接收来自基站设备二上星卡的时钟源信号， 不影响本发明的实现。 参阅图 4-图 5 , 本发明实施例二提供一种星卡资源共享的方法， 该方法中 星卡独立于基站设备（即独立于基站设备一、 基站设备二.…基站设备 Ν ), 增 加了星卡资源共享设备将星卡的数据信号和时钟源信号发送给基站设备， 其 中， 图 4示出了 GPS/GLONASS用户系统共享结构， 图 5示出了星卡资源共 享方法流程，该方法流程中星卡资源共享设备向基站设备一、基站设备二发送 数据信号和时钟源信号仅为示例性描述，本领域人员应当理解， 星卡资源共享 设备会向与之连接的基站设备一、 基站设备二.…基站设备 Ν都发送数据信号 和时钟源信号， 该方法具体包括：
