本实施例中，网络侧设备为基站，在源基站向一个或多个目标基站发送CHO请求后，由源基站发起CHO取消。
一具体示例中，在源基站向一个或多个目标基站发送CHO请求后，如果在预设时间内未收到目标基站如基站B返回的CHO响应，则源基站向基站B发送CHO取消消息，要求取消CHO。
另一具体示例中，在源基站向一个或多个目标基站发送CHO请求后，如果在预设时间内接收到目标基站返回的CHO响应，无论源基站是否已经向用户设备下发CHO命令，在源基站决定取消某个目标基站如基站C或目标基站的某个小区如基站C的某个小区的CHO，源基站都可以向目标基站如基站C发送CHO取消消息，要求取消CHO。
其中，源基站决定取消CHO的原因包括根据UE上报的测量报告判断目标基站或目标基站的某个小区已经不适合作为CHO的目标。
如果在源基站向用户设备下发CHO命令之前，源基站决定取消CHO，则源基站只需要向目标基站发送CHO取消消息，不需要再向UE下发CHO取消消息，其中，CHO取消消息中可以携带取消CHO的原因，以及需要对哪些基站或小区取消CHO。
如果在源基站向用户设备下发CHO命令之后，源基站决定取消CHO，则源基站不仅需要向目标基站发送CHO取消消息，还需要向UE下发CHO取消消息，其中，发送给目标基站的CHO取消消息中可以携带取消CHO的原因，以及需要对哪些基站或小区取消CHO。发送给UE的CHO取消消息 中可以携带需要对哪些基站或小区取消CHO。在UE接收到CHO取消消息后，UE会停止执行对取消CHO的目标基站或小区的CHO条件评估，避免UE评估无效的目标基站或小区，释放UE的处理资源。
实施例二
本实施例中，网络侧设备为基站，在源基站向一个或多个目标基站发送CHO请求后，由目标基站发起CHO取消。
在源基站向一个或多个目标基站发送CHO请求后，如果在预设时间内UE未HO到目标基站，则目标基站可以取消UE CHO到目标基站或目标基站的某个小区。
在目标基站决定取消CHO时，目标基站向源基站发送CHO取消消息，CHO取消消息中可以包括识别CHO命令的信息，如HO命令标识，还可以包括取消CHO的原因，如目标基站的某个小区的负载过高。
在源基站接收到目标基站的CHO取消消息后，源基站向目标基站发送CHO取消确认，确认取消CHO，并且由于UE尚未HO到目标基站，因此，源基站还需要向UE下发CHO取消消息，发送给UE的CHO取消消息中可以携带需要对哪些基站或小区取消CHO，还可以携带识别CHO命令的信息，如HO命令标识。在UE接收到CHO取消消息后，UE会停止执行对取消CHO的目标基站或小区的CHO条件评估，避免UE评估无效的目标基站或小区，释放UE的处理资源。
实施例三
本实施例中，网络侧设备为基站，在源基站向多个目标基站发送CHO请求后，由源基站发起CHO取消。本实施例的CHO取消方法具体包括以下步骤：
步骤1、源基站向多个目标基站发送CHO请求后，源基站接收到多个目标基站返回的CHO响应；
步骤2、源基站接收其中一目标基站返回的UE CHO成功消息；
如果UE成功CHO到该目标基站的小区，则该目标基站向源基站反馈UE CHO成功消息，指示UE已经成功CHO到该目标基站的小区，CHO成 功消息中还可以包括UE成功接入的小区信息和/或该目标基站的信息。
步骤3、源基站向其他目标基站发送CHO取消消息，要求取消CHO。
其中，其他目标基站为源基站发送CHO请求的多个目标基站中，除步骤2中的目标基站之外的其他目标基站，即UE未成功CHO的其他目标基站。其中，CHO取消消息中可以包括取消CHO的原因，比如UE已经成功HO到别的目标基站和/或小区。
实施例四
本实施例中，网络侧设备为基站，如图5所示，在源基站向目标基站1和目标基站2发送CHO请求后，由源基站发起CHO取消。本实施例的CHO取消方法具体包括以下步骤：
步骤1、用户设备向源基站上报测量报告；
步骤2、源基站向目标基站1发送CHO请求消息1，向目标基站2发送CHO请求消息2；
步骤3、目标基站1向源基站返回CHO响应1，目标基站2向源基站返回CHO响应2；
步骤4、用户设备进行无线资源控制RRC(Radio Resource Control，RRC)配置；
包括源基站为用户设备配置一个或多个HO命令；一个或多个HO条件。
步骤5、用户设备的RRC配置完成；
步骤6、用户设备向源基站上报测量报告；
步骤7、源基站向目标基站1发送CHO取消消息1，源基站向目标基站2发送CHO取消消息2；
源基站根据用户设备上报的测量报告判断目标基站1和目标基站2均不适合作为CHO的目标，决定取消CHO。源基站向目标基站1发送CHO取消消息1，源基站向目标基站2发送CHO取消消息2，发送给目标基站的CHO取消消息中可以携带取消CHO的原因，以及需要对哪些基站或小区取消CHO。
步骤8、源基站向UE发送CHO取消消息。
由于是在源基站向用户设备下发CHO命令之后，源基站决定取消CHO， 因此，还需要向UE发送CHO取消消息。
发送给UE的CHO取消消息中可以携带需要对哪些基站或小区取消CHO。在UE接收到CHO取消消息后，UE会停止执行对取消CHO的目标基站或小区的CHO条件评估，避免UE评估无效的目标基站或小区，释放UE的处理资源。
