相关申请的交叉引用
本申请主张在2017年6月23日在中国提交的中国专利申请号No.201710487686.5的优先权，其全部内容通过引用包含于此。
本公开涉及通信技术领域，特别涉及一种信息交互方法、第一基站、第二基站和移动通信终端。
异系统双连接技术是指终端同时连接到两种不同通信制式的系统中进行通信，比如终端同时连接到LTE(Long Term Evolution，长期演进)和5G New Radio(NR，新无线)，即Dual connectivity(DC，双连接)between LTE and NR。
终端进行异系统双连接的同时，在每个系统中还可能使用载波聚合技术，例如，终端进行LTE和5G NR的双连接时，LTE中进行三载波聚合，NR中进行两载波聚合。
当异系统终端双连接技术与载波聚合技术联合使用时，由于终端基带处理能力和射频能力是共享的，因此不同系统之间需要进行终端相应的能力协商。例如，一个终端，可以支持3个载波LTE聚合同时与2个载波聚合的NR进行双连接；也可以支持2个载波的LTE聚合与3个载波的NR进行双连接；还可以支持1个载波的LTE与4个载波聚合的NR进行双连接。
由于终端支持的频段和频段组合过多，因此在异系统双连接场景下终端上报给网络的频段和频段组合支持信息过大，上行开销和负担重。

为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1为本公开一些实施例提供的一种信息交互方法的流程示意图。如图1所示，一种信息交互方法，用于支持异系统双连接和第一通信制式的第一基站，该方法包括以下步骤：
步骤101、接收支持异系统双连接和第二通信制式的第二基站发送的频段信息。
本公开一些实施例应用于支持异系统双连接的两种不同通信制式的两个基站(即第一基站和第二基站)，例如，第一通信制式可以为LTE系统和NR系统中的一个，第二通信制式则为LTE系统和NR系统中的另一个。即，当第一通信制式为LTE系统时，第二通信制式为NR系统；当第一通信制式为NR系统时，第二通信制式为LTE系统。
本公开一些实施例中，第一基站可以与第二基站进行交互，例如，第一基站可以向第二基站发送频段信息，第二基站也可以向第一基站发送频段信息。第一基站(或第二基站)也可以与移动通信终端进行交互，例如，第一基站可以将接收自第二基站的频段信息发送到移动通信终端，移动通信终端也可以将该频段信息对应的频段支持信息发送至第一基站。以下就步骤101至步骤103分别进行具体说明。
该步骤中，第一基站与第二基站进行交互，第二基站可以将其支持的或者感兴趣的频段信息告知与其配对进行双连接的第一基站。具体的，第二基站向第一基站发送上述频段信息，第一基站接收第二基站发送的该频段信息。
其中，基站支持的频段信息，可以理解为基站可以正常工作的频段信息；基站感兴趣的频段信息，可以理解为该基站不支持但该基站的邻近基站支持的频段信息。
其中，频段信息还应当包括频段组合信息，这里，频段组合信息可以理解为载波聚合的频段组合信息。
步骤102、发送所述频段信息到移动通信终端。
该步骤中，第一基站与移动通信终端进行交互，第一基站可以将与其配对进行双连接的第二基站支持的或者感兴趣的频段信息告知移动通信终端。
其中，第一基站向移动通信终端发送的频段信息，可以承载在第一基站到移动通信终端的RRC(Radio Resource Control，无线资源控制协议)信令中。
具体的，第一基站发送该频段信息中的至少一部分到移动通信终端，移动通信终端可以接收到第一基站发送的上述频段信息中的至少一部分。
另外，第一基站可以直接将第二基站发送的频段信息的全部发送到移动通信终端，也可以在对第二基站发送的频段信息进行筛选之后，将频段信息的全部或者部分发送到移动通信终端。对此，本公开一些实施例不作限定。
本公开一些实施例中，第一基站在对频段信息进行筛选之后再发送至移动通信终端，例如，第二基站向第一基站发送的频段信息为f1和f2，若第一基站只支持和f1进行双连接，那么第一基站可以先将与f2相关的信息进行删除，这样，移动通信终端只接收到频段信息f1。
本公开一些实施例能够进一步降低移动通信终端上报的开销。
步骤103、接收所述移动通信终端发送的频段支持信息。
该步骤中，移动通信终端与第一基站进行交互，移动通信终端可以向第一基站上报关于移动通信终端工作在第二通信制式下所支持的频段或者频段组合信息(即频段支持信息)。
移动通信终端上报的频段支持信息可以根据其收到的第一基站发给他的 关于第二基站支持的或感兴趣的频段或频段组合信息进行相应的调整和上报。
具体的，第一基站接收移动通信终端发送的对应于上述频段信息的至少一部分的频段支持信息。
本公开一些实施例中，上述频段信息可以通过第一基站和第二基站之间的接口传输，比如Xn接口；该频段信息也可以通过第二基站到核心网，核心网再到第一基站的方式发送。
本公开一些实施例中，在步骤101之前，第一基站发送用于请求上述频段信息的请求消息到第二基站，从而触发第二基站向第一基站发送该频段信息。
本公开一些实施例中，触发第二基站向第一基站发送该频段信息的条件可以包括以下例举的某一条或者某几条的组合。
条件一：当第一基站与第二基站建立邻区关系后，一种可能的方案是，第一基站发送用于请求上述频段信息的请求消息到第二基站，即第一基站向第二基站索取该信息，第二基站就会触发发送该频段信息给第一基站；另一种可能的方案是，第二基站主动向第一基站发送该频段信息。
条件二：当第一基站决定添加第二基站的载波进行双连接时，第一基站发送用于请求上述频段信息的请求消息到第二基站，第二基站就会触发发送该频段信息给第一基站。
本公开一些实施例中，第一基站接收第二基站发送的频段信息，可以包括以下例举的某一条或者某几条的组合。
条件一：在第二基站在与第一基站建立邻区关系时，第一基站接收第二基站发送的上述频段信息。
条件二：在第二基站在确定与第一基站配合提供双连接服务时，第二基站向第一基站发送上述频段信息。
本公开一些实施例中，第一基站发送频段信息的至少一部分到移动通信终端，可以包括以下例举的某一条或者某几条的组合。
条件一：在第一基站确定与第二基站配合提供双连接服务时，第一基站发送上述频段信息的至少一部分到移动通信终端。
条件二：在移动通信终端初始接入或切换到第一基站的小区时，第一基 站发送上述频段信息的至少一部分到移动通信终端。
本公开一些实施例中，异系统双连接的第一基站可以根据获得的第二基站的频段信息，结合自身频段和频段组合情况来要求移动通信终端上报合适的频段和频段组合支持能力。本公开一些实施例通过基站间的交互实现移动通信终端能力的协调，减少了异系统双连接场景下的移动通信终端上报频段信息的数量，从而降低移动通信终端上报数据的大小。
