具体实施方式
为了使本申请的技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
应了解，在本申请实施例的描述中，如果有描述到“第一”、“第二”等只是用于区分技术特征为第二，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量或者隐含指明所指示的技术特征的先后关系。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示单独存在A、同时存在A和B、单独存在B的情况。其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项”及其类似表达，是指的这些项中的任意组合，包括单项或复数项的任意组合。例如，a，b和c中的至少一项可以表示：a，b，c，a和b，a和c，b和c或a和b和c，其中a，b，c可以是单个，也可以是多个。
此外，下面所描述的本申请各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
为了便于理解，首先对本申请实施例涉及的相关的技术方案进行简单介绍。
相关的技术方案中，如图1所示，LTE网络的基站eNB和NR网络的基站gNB开展小区之间的协同业务时，协同小区需要进行一系列的协同数据交互，例如协同小区配置信息、UE配置信息、基带协同信息等。目前3GPP协议中，eNB和gNB的小区之间的交互是通过X2/Xn方式完成，但是这种方式，数据流需要经过eNB和gNB的CU的CPU处理，导致交互过程时延值较大，当时延值一旦大于阈值，则导致协同小区不能及时协作，从而开展协同业务失败。
为解决上述技术问题，本申请实施例提供了一种第一基站、第二基站、系统、数据传输方法、电子设备和计算机可读存储介质，基站之间的协同数据传输无需CU的CPU参与，能够有效的缩短协同数据传输时延，提高了协同业务的服务稳定性。
图2示出了本申请实施例提供的一种系统的结构示意图。如图2所示，该系统包括第一基站和第二基站。第一基站和第二基站可以为不同代际网络的基站，例如，第一基站为4G LTE网络的基站eNB，第二基站为5G NR网络的基站gNB。当然，第一基站和第二基站也可以为同代际网络的基站，例如，第一基站和第二基站均为5G NR网络的基站gNB，本申请实施例对 此不作具体限制。
如图2所示，本申请实施例的第一基站包括第一集中单元(Central Unit，CU)和第一分布单元(Distributed Unit，DU)，第一CU包括第一主控板，第一主控板包括第一主控板交换芯片，第一DU包括第一基带板，其中，第一DU中的第一基带板的数量可以为一个或者多个。
本申请实施例的第一基带板交换芯片，被设置成向第一主控板交换芯片发送携带地址标识信息和协同数据的协同报文。
本申请实施例的第一主控板交换芯片，被设置成接收第一基带板交换芯片发送的协同报文，根据协同报文中的地址标识信息将协同报文转发至第二基站的第二主控板交换芯片，其中，第二主控板交换芯片设置于第二基站的第二CU中。
可以理解的是，第一基站的各个小区分别对应一个第一基带板，当第一基站的小区需要与外部基站的小区进行协同数据交互时，小区所属的第一基带板交换芯片获取协同数据对应的地址标识信息，将该地址标识信息和协同数据组装成协同报文，将协同报文发送至第一主控板交换芯片，以由第一主控板交换芯片将协同报文转发至外部基站的小区。
在一些示例中，地址标识信息可以包括：源子系统标识、源小区标识、源基站标识、目的基站标识、目的小区标识和目的子系统标识。当然，这里只是对地址标识信息所包含的信息进行示意性的描述，具体应用时，地址标识信息可以包括更多或者更少的信息，本申请实施例对此不作具体限定。
应理解的是，本申请实施例中描述的第一基站即为源基站；源小区为第一基站下的小区，源小区对应于一个第一基带板；源子系统为第一基站下存储有协同数据的子系统。
可以理解的是，第一基带板向第一主控板发送协同报文，具体可以包括：根据预先配置的访问控制列表(Access Control List，ACL)规则和地址标识信息确定第一主控板交换芯片的Mac地址，根据第一主控板交换芯片的Mac地址向第一主控板交换芯片发送协同报文。
可以理解的是，为了实现多小区协同，可以在网络设备管理服务器上配置基站间/小区间的协同关系，并根据协同关系构建协同信息路由表。协同信息路由表可以包括参与协同的小区标识、基站标识、子系统标识，以及基站标识对应的IP地址等等。具体实现过程中，通过网络设备管理服务器将协同信息路由表以及ACL规则下发至参与协同的基站的CU的CPU中，由CU的CPU将协同信息路由表和ACL规则配置到所在基站的主控板交换芯片、基带板交换芯片中。
在第一基带板侧具有待向外部基站发送的协同报文时，第一基带板交换芯片从协同报文获取地址标识信息，将地址标识信息包含的标识作为关键字段，在协同信息路由表中进行关键字段匹配，当所有关键字段全部匹配时，可确认当前的协同关系是唯一的，并根据与关键字段相匹配的ACL规则，调用底层硬件接口以获取与该源基站标识匹配的Mac地址，这里的Mac地址具体为第一主控板交换芯片的Mac地址。
在一些示例中，第一基带板交换芯片在确定第一主控板交换芯片的Mac地址之后，可以将该Mac地址写入协同报文中，进而根据协同报文中的Mac地址向第一主控板交换芯片发送该协同报文。
在一些示例中，本申请实施例的方法还可以包括：第一基带板交换芯片根据预先配置的ACL规则和地址标识信息确定第二基站的IP地址，并向协同报文写入该第二基站的IP地址。 应理解的是，这里的第二基站即为目的基站。
在一些示例中，第一基带板交换芯片可以从地址标识信息中提取出目的基站标识，根据目的基站标识，从本地存储的ACL规则中查找与该目的基站标识匹配的IP地址，进而将该目的基站的IP地址写进协同报文中。
可以理解的是，第一主控板交换芯片接收到第一基带板交换芯片发送的协同报文之后，根据预先配置的ACL规则和协同报文中的地址标识信息，确定第二基站的第二主控板交换芯片的Mac地址，以根据第二基站的第二主控板交换芯片的Mac地址，将协同报文转发至第二基站的第二主控板交换芯片。
在一些示例中，当第一主控板交换芯片接收到第一基带板交换芯片发送的协同报文之后，可以从协同报文中的地址标识信息中提取出目的基站标识，根据该目的基站标识，根据本地存储的ACL规则调用底层硬件接口以获取查找与该目的基站标识匹配的Mac地址，这里的Mac地址具体为第二基站的第二主控板交换芯片的Mac地址，第二主控板交换芯片设置于第二基站的第二CU中。
在一些示例中，当协同报文中包含第一主控板交换芯片的Mac地址时，第一主控板交换芯片在确定第二主控板交换芯片的Mac地址之后，可以将协同报文中的第一主控板交换芯片的Mac地址更新为第二主控板交换芯片的Mac地址，进而在第一主控板交换芯片向第二主控板交换芯片发送该协同报文时，可以根据协同报文中的第二主控板交换芯片的Mac地址执行发送操作。
如图2所示，本申请实施例的第二基站包括第二CU和第二DU，第二CU包括第二主控板，第二主控板包括第二主控板交换芯片，第二DU包括第二基带板，其中，第二DU中的第二基带板的数量可以为一个或者多个。
本申请实施例的第二主控板交换芯片，被设置成接收第一基站的第一主控板交换芯片发送的携带地址标识信息和协同数据的协同报文，根据协同报文中的地址标识信息向第二基带板交换芯片转发协同报文，其中，第一主控板交换芯片设置于第一基站的第一CU中。
本申请实施例的第二基带板交换芯片，被设置成接收第二主控板交换芯片发送的协同报文，根据协同报文中的地址标识信息确定存储地址，将协同报文中的协同数据存储至与存储地址对应的存储空间。
可以理解的是，第二主控板交换芯片接收到第一基站的协同报文之后，可以根据预先配置的访问控制列表ACL规则和协同报文中的地址标识信息确定第二基带板交换芯片的Mac地址，以根据第二基带板交换芯片的Mac地址向第二基带板交换芯片发送协同报文。
在一些示例中，地址标识信息可以包括：源子系统标识、源小区标识、源基站标识、目的基站标识、目的小区标识和目的子系统标识。当然，这里只是对地址标识信息所包含的信息进行示意性的描述，具体应用时，地址标识信息可以包括更多或者更少的信息，本申请实施例对此不作具体限定。
在一些示例中，第二主控板交换芯片接收到来自第一基站的协同报文之后，可以从协同报文中的地址标识信息中提取出目的小区标识，根据该目的小区标识，根据本地存储的ACL规则中调用底层硬件接口以获取与该目的小区标识匹配的Mac地址，这里的Mac地址具体为目的小区所在的第二基带板交换芯片的Mac地址。
可以理解的是，某些实施例中，第二主控板交换芯片接收到的协同报文中携带有第二主 控板交换芯片的Mac地址。当协同报文中携带有第二主控板交换芯片的Mac地址，第二主控板交换芯片在确定第二基带板交换芯片的Mac地址之后，可以将协同报文中的第二主控板交换芯片的Mac地址更新为第二基带板交换芯片的Mac地址，进而第二主控板交换芯片在向第二基带板交换芯片发送该协同报文时，可以根据协同报文中的第二基带板交换芯片的Mac地址执行发送操作。
本申请实施例的第二基带板交换芯片从第二主控板交换芯片接收协同报文，根据协同报文中的地址标识信息确定存储地址，将协同报文中的协同数据存储至与存储地址对应的存储空间，从存储空间读取协同数据。
可以理解的是，第二基带板交换芯片从第二主控板交换芯片接收到协同报文之后，根据地址标识信息和预先配置的哈希表(Hash table)，通过哈希匹配确定存储地址，将协同报文中的协同数据存储至与存储地址对应的存储空间。
可以理解的是，第二基带板交换芯片上预先配有哈希表。哈希表是包含多个哈希条目的具有内存映射关系信息的数据结构。本申请实施例基于协同报文中的地址标识信息字段，通过哈希匹配，确定协同数据所对应的存储空间。
如图3所示，具体实现过程中，可以使存储协同数据的内存空间根据目的子系统、目的小区，源小区、子帧号、源子系统、子消息进行逐层划分。设图3中目的小区的空间个数为LocMax个且大小相同，源小区的空间个数为NbrMax且大小相同，子帧号为SfMax个空间大小相同，源子系统每个空间大小不同，子消息对于的每个空间大小不同。目的子系统对应一个基地址BaseAddr，每个子帧对应的空间大小为SubFrmSize，源子系统标识和子消息编号相加能得到对应一个该空间内的偏移量为Offset。如此，根据目的小区标识LocalBufID、源小区标识NbrBufID、子帧号SFN、以及源子系统标识和子消息编号相加的偏移量Offset，可以得到协同数据的存储地址为：
BaseAddr+(LocalBuflID*NbrMax*SfMax+NbrBufID*SfMax+SFN)*SubFrmSize+Offset
第二基带板交换芯片通过哈希匹配得到协同数据的存储地址之后，第二基带板交换芯片可以将Mac地址头、IP地址头、地址标识信息头从协同报文剥离，进而将余下的协同数据存放到存储地址指示的存储空间中。
具体应用中，第二基带板的CPU可以采用轮询的方式从存储空间中读取协同数据，完成协同数据的接收。
以下结合图2，通过具体示例对本申请实施例的系统进行描述。
如图2所示，图2所示系统包括第一基站和第二基站。其中，第一基站包括第一CU和第一DU，第一CU包括第一主控板，第一主控板包括第一主控板交换芯片，第一DU包括至少一个第一基带板，第一基带板包括第一基带板交换芯片；第二基站包括第二CU和第二DU，第二CU包括第二主控板，第二主控板包括第二主控板交换芯片，第二DU包括至少一个第二基带板，第二基带板包括第二基带板交换芯片。
在一些示例中，第一基站的第一主控板交换芯片可以通过光纤与第二基站的第二主控板交换芯片连接，实现第一基站和第二基站间的数据交互。
第一基带板交换芯片接收第一基带板CPU发送的协同数据后，获取协同数据对应的地址标识信息，其中，该地址标识信息包括源子系统标识、源小区标识、源基站标识、目的基站标识、目的小区标识和目的子系统标识。
第一基带板交换芯片预先配置有ACL规则，从先前确获取的地址标识信息提取源基站标识，通过ACL匹配得到第一主控板交换芯片的Mac地址；还根据先前确定的地址标识信息提取目的基站标识，通过ACL匹配得到第二基站的IP地址。
第一基带板交换芯片基于前面得到的第一主控板CPU的Mac地址、第二基站的IP地址、地址标识信息和原始的协同数据进行数据组装，生成协同报文。协同报文的报文结构可以参见图4所示，包括：Mac地址头、IP地址头、地址标识信息头和协同数据。

第二基带板CPU以轮询的方式读取存储空间中的协同数据，完成协同数据的接收。
本申请实施例的技术方案，源小区所在的基带板交换芯片将地址标识信息写入协同数据中，使得各个传输节点可以根据地址标识信息，通过ACL匹配得到下一跳节点的Mac地址，进而根据下一跳节点的Mac地址进行协同报文的转发，实现最终将协同数据转发至目的小区所在的基带板。本申请实施例中，整个协同报文传输过程无需CU的CPU参与，能够有效的缩短协同数据传输时延，提高了协同业务的服务稳定性。
