具体实施方式
现有的基于人工智能(Artificial Intelligence，AI)通信模型的下行信道压缩反馈，需要终端和基站的配合，即位于终端侧的编码网络模型和位于基站端 的解码网络模型的配合。
具体的，终端与基站协商好下行信道反馈所需的AI编码模型和AI解码模型后，基站周期性的发送CSI-RS，终端接收到CSI-RS后，进行信道估计，并使用编码模型进行压缩量化后，向终端发送压缩过后的信道信息，基站接收到后，根据协商好的AI解码模型对信道信息进行解压，获取完整的下行信道估计信息。
但是，终端在基站之间切换的时候可能会遇到以下问题：
(1)当切换的候选基站中有支持和不支持AI的解码网络模型的时候，如何选择切换基站。
(2)当切换后的目标基站有更新的编码和解码网络模型，如何告知终端。
(3)当切换后的目标基站不支持AI的解码网络模型的时候，如何回退。
基于上述问题，本申请给出了一种通信方法，能够在切换的候选基站中有支持和不支持AI的解码网络模型的时候，通过基站间节点配置更新，源基站可以更好的选择目标基站，并且当切换后的目标基站不支持AI的解码网络模型的时候，网络可以及时告知终端进行回退。

  7. 一种源基站，所述基站包括：
    第一获取单元，配置为向目标基站发送切换请求，并接收所述目标基站发送的切换请求响应消息，从所述切换请求响应消息中获取基站通信信息；
    所述第一获取单元，还配置为若所述基站通信信息为所述目标基站支持编解码模型通信的信息，则从所述切换请求响应消息中获取目标编码模型信息；
    所述第一发送单元，还配置为将携带所述目标编码模型信息的RRC重配消息发送至所述终端，以供所述终端根据所述目标编码模型信息确定与所述目标基站进行通信的目标编码模型。
  8. 一种目标基站，所述目标基站存储预设通信模型对信息，所述基站包括：
    确定单元，配置为在接收到源基站发送的切换请求的情况下，确定所述目标基站的基站通信类型；所述切换请求中携带终端的当前编码模型信息；
    第二获取单元，配置为若确定出所述目标基站的基站通信类型为支持通过编解码模型通信，则从所述切换请求中获取所述当前编码模型信息；
    所述确定单元，还配置为根据所述预设通信模型对信息和所述当前编码模型信息确定与所述终端通信的目标通信模型信息；
    添加单元，配置为将所述目标通信模型信息中的目标编码模型信息和支持通过编解码模型通信的基站通信信息添加至切换请求响应消息中；
    第二发送单元，配置为将所述切换请求响应消息发送至所述源基站。
  9. 一种源基站，其中，所述基站包括：第一处理器、第一发送器、第一存储器及第一通信总线；所述第一处理器执行第一存储器存储的运行程序时实现如权利要求1-4任一项所述的方法。
  10. 一种目标基站，其中，所述基站包括：第二处理器、第二发送器、第二存储器及第二通信总线；所述第二处理器执行第二存储器存储的运行程序时实现如权利要求5-6任一项所述的方法。
  11. 一种第一存储介质，其上存储有计算机程序，其中，该计算机程序被第一处理器执行时实现如权利要求1-4任一项所述的方法。
  12. 一种第二存储介质，其上存储有计算机程序，其中，该计算机程序被第二处理器执行时实现如权利要求5-6任一项所述的方法。
