当地面无线通信信号和卫星通信信号共存的场景下，为了降低用户通信费用，同时节省卫星传输系统功耗，比如：海上安装了卫星系统的船只靠港，安装了卫星系统的飞机着陆后，就可以考虑关断用户终端和卫星传输系统之间链路，或者通知用户终端切换通信链路的方式，让用户终端切换到地面无线通信系统进行传输，以降低通信成本。
对于当地面无线通信信号和卫星通信信号共存的场景，相关技术中的做法是：人工操作关闭卫星系统或卫星传输链路，以实现通信链路的切换。这种通信链路切换方式存在操作不及时、不够智能的问题。

在一实施例中，在卫星系统和用户终端之间的通信链路被切断后，本申请实现链路切换的方法还包括：
如果再次获取的信息不再满足预先设置的通信链路切换条件，比如：获取的位置信息不在预先设置的切换位置参数范围内；或者，获取的无线通信信号不可用；或者，获取的位置信息不在预先设置的切换位置参数范围内或获取的无线通信信号不可用；或者，获取的位置信息不在预先设置的切换位置参数范围内且获取的无线通信信号不可用，那么，开启卫星系统和用户终端之间的通信链路，或者通知用户终端切换为卫星系统的通信链路。

下面结合具体应用场景对本申请实现链路切换的方法进行详细描述。
第一实施例，仅通过采集位置信息来进行决策是否需要进行链路切换。
第一实施例中，假设用户终端已通过WiFi或2G或3G或4G或5G等信号或有线方式连接到卫星系统，并通过卫星系统传输进行通信。卫星系统的卫星远端站按照预先设置的周期采集自身地理位置信息。
卫星远端站比较采集到的位置信息和预先设置的切换位置参数范围，如果采集到的位置信息进入到预先设置的切换位置参数范围的区域，那么，卫星远端站可以通知用户终端进行传输链路切换，也可以直接关闭卫星系统和用户终端之间通信链路，使用户终端切换到其他通信系统的传输链路进行通信。
当卫星远端站离开预先设置的切换位置参数范围的区域，那么，卫星远端站开启卫星系统和用户终端之间的传输链路，这样用户终端又可以通过卫星传输系统进行通信。
第二实施例，仅通过采集周边其他无线通信信号进行决策是否需要进行链路切换。
第二实施例中，假设用户终端已通过WiFi或2G或3G或4G或5G等信号或有线方式连接到卫星系统，并通过卫星系统传输进行通信。卫星系统的卫星远端站按照预先设置的周期采集周围无线通信信号。
卫星远端站可以根据采集到的周围无线通信信号中是否包含有预先设置的运营商标示，如果包含有，那么，判断周围无线通信信号是可用的。卫星远端站也可以与获取的周边无线通信信号建立链路链接，并与互联网通信，如果通信成功，那么，判断周围无线通信信号是可用的。
在判断出周围无线通信信号是可用的，卫星远端站可以通知用户终端进行传输链路切换，也可以直接关闭卫星系统和用户终端之间通信链路，使用户终端切换到其他通信系统的传输链路进行通信。
当卫星远端站判断出周围无线通信信号不可用，那么，卫星远端站开启卫星系统和用户终端之间的传输链路，这样用户终端又可以通过卫星传输系统进行通信。
在一实施例中，为了确保判断出的可用的周围无线通信信号确实能用，还可以进一步判断获取的无线通信信号的强度是否强于预先设置的信号阈值，如果强于预先设置的信号阈值，则才通知用户终端进行传输链路切换，或直接关 闭卫星系统和用户终端之间通信链路，使用户终端切换到其他通信系统的传输链路进行通信。
第三实施例，通过采集位置信息或采集周边其他无线通信信号进行决策是否需要进行链路切换。
第三实施例中，假设用户终端已通过WiFi或2G或3G或4G或5G等信号或有线方式连接到卫星系统，并通过卫系统传输进行通信。卫星系统的卫星远端站按照预先设置的周期采集自身地理位置信息，或者按照预先设置的周期采集周围无线通信信号。
卫星远端站比较采集到的位置信息和预先设置的切换位置参数范围，判断采集到的位置信息是否进入到预先设置的切换位置参数范围的区域；或者，卫星远端站可以根据采集到的周围无线通信信号中是否包含有预先设置的运营商标示，或卫星远端站也可以与获取的周边无线通信信号建立链路链接，确定是否能与互联网通信。
如果采集到的位置信息进入到预先设置的切换位置参数范围的区域；或者，采集到的周围无线通信信号中包含有预先设置的运营商标示或与互联网通信成功，那么，判断出周围无线通信信号是可用。此时，卫星远端站可以通知用户终端进行传输链路切换，也可以直接关闭卫星系统和用户终端之间通信链路，使用户终端切换到其他通信系统的传输链路进行通信。
当卫星远端站离开预先设置的切换位置参数范围的区域，或者，当卫星远端站判断出周围无线通信信号不可用，那么，卫星远端站开启卫星系统和用户终端之间的传输链路，这样用户终端又可以通过卫星传输系统进行通信。
在一实施例中，为了确保判断出的可用的周围无线通信信号确实能用，还可以进一步判断获取的无线通信信号的强度是否强于预先设置的信号阈值，如果强于预先设置的信号阈值，则才通知用户终端进行传输链路切换，或直接关闭卫星系统和用户终端之间通信链路，使用户终端切换到其他通信系统的传输链路进行通信。
第四实施例，通过采集位置信息和采集周边其他无线通信信号进行决策是否需要进行链路切换。
第四实施例中，假设用户终端已通过WiFi或2G或3G或4G或5G等信号或有线方式连接到卫星系统，并通过卫星系统传输进行通信。卫星系统的卫星远端站按照预先设置的周期采集自身地理位置信息，同时按照预先设置的周期 采集周围无线通信信号。
卫星远端站比较采集到的位置信息和预先设置的切换位置参数范围，判断采集到的位置信息是否进入到预先设置的切换位置参数范围的区域；并且，卫星远端站可以根据采集到的周围无线通信信号中是否包含有预先设置的运营商标示，或卫星远端站也可以与获取的周边无线通信信号建立链路链接，确定是否能与互联网通信。
如果采集到的位置信息进入到预先设置的切换位置参数范围的区域；并且，采集到的周围无线通信信号中包含有预先设置的运营商标示或与互联网通信成功，那么，判断出周围无线通信信号是可用。此时，卫星远端站可以通知用户终端进行传输链路切换，也可以直接关闭卫星系统和用户终端之间通信链路，使用户终端切换到其他通信系统的传输链路进行通信。
当卫星远端站离开预先设置的切换位置参数范围的区域，或者，当卫星远端站判断出周围无线通信信号不可用，那么，卫星远端站开启卫星系统和用户终端之间的传输链路，这样用户终端又可以通过卫星传输系统进行通信。
在一实施例中，为了确保判断出的可用的周围无线通信信号确实能用，还可以进一步判断获取的无线通信信号的强度是否强于预先设置的信号阈值，如果强于预先设置的信号阈值，则才通知用户终端进行传输链路切换，或直接关闭卫星系统和用户终端之间通信链路，使用户终端切换到其他通信系统的传输链路进行通信。
