本公开涉及通信领域，例如，涉及一种切换方法、切换装置及网络系统。
背景技术
第五代(5th Generation，5G)移动通讯系统中，5G基站称为新一代无线接入网节点(New Generation Radio Access Network Node，NG RAN Node，gNB)，gNB之间的接口称为Xn接口，gNB和其他非5G基站之间的接口为X2接口。另外，5G基站支持CU/DU分离架构。一个分离的5G基站，可分为集中单元(gNB Centralized Unit，gNB-CU)与分布单元(gNB Distributed Unit，gNB-DU)两部分。一个分离的5G基站内部只有一个gNB-CU作为集中式控制节点，一个gNB-CU可以连接并管理多个gNB-DU，一个gNB-DU通过F1接口和一个gNB-CU相连。
相关技术中，无线网络的小区会评估一些信息，如小区物理资源块(Physical Resource block，PRB)利用率情况来评估小区负荷，当小区负荷不均衡时，会影响网络服务，例如某些小区负荷较高时，会导致该小区服务质量降低，某些小区负荷较低又会造成资源浪费和电力浪费；并且，小区的负荷波动较大，导致小区负荷很难保持较为均衡的状态。
针对相关技术中的小区负荷不均衡从而影响网络服务的问题，尚不存在解决方案。

可选实施方式
本实施例涉及无线通信系统技术领域，例如，涉及一种基于负荷预测的通信方法，无线网络引入人工智能(Artificial Intelligence，AI)和机器学习技术可以更好的预测将来的网络负荷，并用于网络通信管理决策。
在本实施例中，无线网络的小区可以评估一些信息，如小区PRB(Physical Resource Block，物理资源块)利用率情况来评估小区负荷，如果判定服务小区 处于高负荷状态，则执行负荷均衡，将部分用户向相邻低负荷小区切换，邻区的小区负荷状态可以通过X2/XN口获取。并且相关邻区负荷信息也可以用于切换过程中根据负荷选择更合适的切换目标小区。本小区评估的小区负荷也可以用来节能，比如本小区负荷很低，则可以关闭本小区节省电量，并将本小区剩余用户切换到其他低负荷邻区。由于整个网络的负荷是实时变动的，下面一个时间点可能会发生较大的变化，有些负荷是具有周期性特征，仅仅根据当前负荷信息来做出切换/节能/和负荷均衡的判决并不充分，可能会导致用户切换到一个新的目标小区后，目标小区后续负荷迅速升高，导致目标小区无法满足用户服务质量。所以可以根据预测负荷确定切换的目标小区，小区信息中的预测负荷信息用于标明预测的目标网元上管理的某个小区在未来下一个时间周期或者未来多个时间周期平均负荷信息，所述时间周期可以是若干秒，若干分钟，若干小时或者其他时间粒度。负荷信息可以采用以下一项或者多项表示：功率消耗；无线资源消耗；硬件负荷；beam负荷。

可选地，目标网元的小区预测负荷可以采用人工智能的方式预测，所述负荷可以采用以下一项或者多项表示：功率消耗；无线资源消耗；硬件负荷；beam负荷。
可选地，源网元和目标网元可以是基站。源基站接收一个或者多个目标基站发送的消息A，根据消息A中包含的小区辅助信息进行切换判决。源基站根据小区辅助信息中的负荷预测信息，将选择一个预测负荷小的目标小区作为判决准则之一，选择一个目标网元上的目标小区，将当前服务小区的某些指定用户切换到目标小区。
可选地，源网元可以是gNB-CU，目标网元可以是gNB-DU。gNB-CU接收本基站的一个或者多个gNB-DU发送的消息B，根据消息B中包含的小区辅助信息进行切换：gNB-CU根据小区辅助信息中的负荷预测信息，将选择一个预测负荷小的目标小区作为判决准则之一，选择一个目标网元上的目标小区，将当前服务小区的某些指定用户切换到目标小区。

可选地，源网元可以是gNB-CU，目标网元可以是gNB-DU。gNB-CU接收本基站的一个或者多个gNB-DU发送的消息B，gNB-CU根据本基站某个指定服务小区的负荷信息以及根据消息B中包含的小区辅助信息进行节能操作：gNB-CU所属的基站当前某个服务小区的负荷信息小于某个门限，且存在目标gNB-DU所属的目标小区，将目标小区的预测负荷小于某个门限作为判决准则之一，可选的，该目标小区根据小区辅助信息中的小区覆盖关系需要和当前服务小区存在同覆盖，则gNB-CU关闭当前指定的服务小区用于节能，并将当前服务小区的用户切换到目标小区。所述关闭服务小区，可以是关闭整个小区，或者是关闭小区部分载波，或者是关闭小区部分射频通道，或者是关闭小区部分符号资源。
可选地，源网元可以发送消息C给目标网元，消息C中包含小区负荷上报类型指示，用来指示目标网元在发送小区辅助信息的时候，是携带以下一项或者多项负荷信息：小区当前负荷信息，小区预测负荷信息。
