在长期演进LTE系统中，E-UTRAN(Evolved UMTS Terrestrial Radio Access Network，演进的通用移动通信系统陆地无线接入网)，由多个eNB(4G基站)组成，eNB与分组核心网EPC之间通过S1接口连接，eNB之间通过X2接口连接，为了支持更高的数据吞吐量，用户设备UE可以通过两个eNB实现双连接。
在5G系统中，同样的，和LTE系统的双连接类似，也支持eNB和gNB(5G基站)的紧耦合互操作(tight interworking)。考虑到5G基站可能部署在高频，小区的覆盖范围比较小，而小区的物理层标识(PCI)数量有限，在一个eNB的覆盖范围内，可能有多个NR(新空口)小区分配了相同的PCI，产生PCI冲突。

具体实施方式
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。
本公开针对相关技术中的紧耦合场景下，gNB无法确定eNB请求的部分NR小区与eNB的小区的关系，降低了为UE确定目标SCG CELL的准确性的问题，提供了一种紧耦合处理方法，告知gNB具体的eNB请求的部分NR小区与eNB所属小区邻区关系，解决了准确地为UE确定目标SCG CELL的问题。
如图1所示，本公开实施例的一种紧耦合处理方法，应用于第一基站，包括：
步骤101，发送第一小区与第二小区之间的关联信息至第二基站；其中，
所述第一小区为归属于第一基站的小区，所述第二小区为第一基站请求的，且归属于第二基站的小区。
本公开实施例的方法，适用于紧耦合场景，其中，第一小区为归属于第一基站的小区；第二小区为第一基站请求的，且归属于第二基站的小区，这样，第一基站通过发送第一小区与第二小区之间的关联信息至第二基站，就能够使第二基站明确两基站的小区级的关联，从而在后续为UE确定目标SCG CELL时候，更加准确。
这里，第一基站和第二基站为异系统基站，可选地，第一基站为eNB，第二基站为gNB。
应该知道的是，该实施例中，考虑到为UE执行紧耦合需要在eNB和gNB之间建立X2/Xn接口，可选地，步骤101包括：
发送携带有所述关联信息的4G-5G双连接配置更新EN-DC Configuration update消息至第二基站；或者
发送携带有所述关联信息的5G接入网节点配置更新NG RAN NODE Configuration update消息至第二基站。
这里，对于eNB和gNB的X2接口建立过程，eNB发送至gNB的EN-DC Configuration update消息，通过携带第一小区与第二小区之间的关联信息，将第一小区与第二小区之间的关联信息告知于gNB；对于eNB和gNB的Xn接口建立过程，eNB发送至gNB的NG RAN NODE Configuration update消息，通过携带第一小区与第二小区之间的关联信息，将第一小区与第二小区之间的关联信息告知于gNB。
在本公开的实施例中，可选地，一方面，所述第一小区与第二小区之间的关联信息为：第一小区与所述第一小区所请求的第二小区之间的对应关系。
这里，第一小区与第二小区之间的关联信息是针对第一基站下的小区，对第一小区与该第一小区所请求的第二小区之间的对应关系进行的描述。
假设eNB的小区包括Cell 1、Cell 2和Cell 3，eNB请求的gNB部分邻 区Cell A、Cell B、Cell C和Cell D，Cell 1所请求的第二小区是Cell A和Cell B，Cell 2所请求的第二小区是Cell C，Cell 3所请求的第二小区是Cell D，此时，第一小区与第二小区之间的关联信息就可以记录为Cell 1-(Cell A和Cell B)，Cell 2-Cell C，Cell 3-Cell D。
具体地，这一形式的关联信息，可以由小区辅助信息Cell Assistance Information的限量清单limited list IE下增加一个LTE小区清单LTE cell list，如下表1所示：
表1
Figure PCTCN2019086016-appb-000001
Figure PCTCN2019086016-appb-000002
另一方面，所述第一小区与第二小区之间的关联信息为：第二小区与请求了所述第二小区的所有第一小区之间的对应关系。
这里，第一小区与第二小区之间的关联信息是针对第一基站请求的第二基站的小区，对第二小区与请求了该第二小区的所有第一小区之间的对应关系进行的描述。
同样的，假设eNB的小区包括Cell 1、Cell 2和Cell 3，eNB请求的gNB部分邻区Cell A、Cell B、Cell C和Cell D，Cell 1所请求的第二小区是Cell A和Cell B，Cell 2所请求的第二小区是Cell C，Cell 3所请求的第二小区是Cell D，此时，第一小区与第二小区之间的关联信息就可以记录为CellA-Cell 1，Cell B-Cell 1，Cell C-Cell 2，Cell D-Cell 3。
具体地，上述形式的关联信息，可以由Cell Assistance Information的List of Requested NR Cells IE中增加每个NR小区对应的LTE小区标识，如下表2所示：
表2
Figure PCTCN2019086016-appb-000003
Figure PCTCN2019086016-appb-000004
通过上述内容，可以知道的是，第二基站(即gNB)通过接收第一基站(即eNB)发送的第一小区与第二小区之间的关联信息，就能够了解到eNB的小区和自身小区中eNB请求的小区的对应关系。具体地，gNB接收携带有关联信息的EN-DC Configuration update消息；或者接收携带有关联信息的NG RAN NODE Configuration update消息。
之后，当eNB下的UE发起测量上报，如图2所示，本公开实施例的方法还包括：
步骤201，根据接收到的用户设备的测量报告，发送辅基站添加请求SgNB Addition request消息至所述第二基站，SgNB Addition request消息携带有所述用户设备在所述第一基站的服务小区的标识以及目标辅小区组主小区SCG CELL的物理层标识PCI；
步骤202，接收所述第二基站返回的辅基站添加应答SgNB Addition response消息，SgNB Addition response消息携带有所述第一基站根据所述服务小区的标识以及目标SCG CELL的PCI查找到的第三小区的标识；
步骤203，根据所述第三小区的标识为所述用户设备进行紧耦合配置。
如此，eNB根据接收到UE的测量报告，决定为该UE增加SCG CELL 的时候，发送SgNB Addition request消息至gNB，gNB Addition request消息携带有UE在该eNB的服务小区的标识以及目标SCG CELL的PCI，使得gNB能够基于该服务小区的标识、目标SCG CELL的PCI以及之前已知的第一小区与第二小区之间的关联信息，精确查询到对应服务小区的第三小区的标识，第三小区即为目标SCG CELL。而eNB通过接收gNB发送的携带该第三小区的标识的SgNB Addition response消息，根据该第三小区的标识为UE进行紧耦合配置，提升了为UE确定目标SCG CELL的准确性。
其中，所述第一小区与第二小区之间的关联信息中包括所述第一小区的标识，所述第一小区的标识为：
演进的通用移动通信系统陆地无线接入网小区全局标识符ECGI；或者
PCI和频点。
这里，因第一小区是归属于eNB的，既可通过ECGI唯一标识该第一小区，也可通过PCI和频点共同来唯一标识该第一小区，所以，第一小区与第二小区之间的关联信息中该第一小区的标识为ECGI；或者PCI和频点。
然而，归属于gNB的第二小区，需使用NR-CGI进行唯一标识，所以，所述第一小区与第二小区之间的关联信息中包括所述第二小区的标识，所述第二小区的标识为：新空口小区全局标识符NR-CGI。
下面结合附图说明本公开实施例的方法在紧耦合场景下的应用：
场景一、如图3所示，eNB和gNB之间需建立X2接口连接
S301，eNB向gNB发送4G-5G双连接X2建立请求EN-DC X2 Setup request消息；
S302，gNB返回4G-5G双连接X2建立应答EN-DC X2 Setup response消息；
S303，eNB向gNB发送EN-DC Configuration update消息，该消息携带第一小区与第二小区之间的关联信息，第一小区为归属于eNB的小区，所述第二小区为eNB请求的，且归属于gNB的小区；
S304，gNB保存第一小区与第二小区之间的关联信息，并返回4G-5G双连接配置更新确认EN-DC Configuration update ACK消息；
S305，eNB下的UE发送测量报告Measurement report；
S306，eNB根据UE上报的Measurement report决定为该UE增加SCG CELL，向gNB发送SgNB Addition request消息，SgNB Addition request消息携带该UE在eNB的服务小区的标识(ECGI或者(PCI和频点))以及目标SCG CELL的PCI；
S307，gNB根据UE在eNB的服务小区的标识、目标SCG CELL的PCI以及之前接收到的第一小区与第二小区之间的关联信息，查找到添加的目标SCG CELL的标识，向eNB发送携带目标SCG CELL的标识的SgNB Addition response消息；
S308，eNB基于gNB告知的目标SCG CELL的标识，通过无线资源控制协议重构RRC reconfiguration消息为UE进行紧耦合配置。

S401，eNB向gNB发送Xn建立请求X2 Setup request消息；
S402，gNB返回Xn建立应答X2 Setup response消息；
S403，eNB向gNB发送NG RAN NODE Configuration update消息，该消息携带第一小区与第二小区之间的关联信息，第一小区为归属于eNB的小区，所述第二小区为eNB请求的，且归属于gNB的小区；
S404，gNB保存第一小区与第二小区之间的关联信息，并返回5G接入网节点配置更新确认NG RAN NODE Configuration update ACK消息；
S405，eNB下的UE发送Measurement report；
S406，eNB根据UE上报的Measurement report决定为该UE增加SCG CELL，向gNB发送SgNB Addition request消息，SgNB Addition request消息携带该UE在eNB的服务小区的标识(ECGI或者(PCI和频点))以及目标SCG CELL的PCI；
S407，gNB根据UE在eNB的服务小区的标识、目标SCG CELL的PCI以及之前接收到的第一小区与第二小区之间的关联信息，查找到添加的目标SCG CELL的标识，向eNB发送携带目标SCG CELL的标识的SgNB Addition response消息；
S408，eNB基于gNB告知的目标SCG CELL的标识，通过RRC reconfiguration消息为UE进行紧耦合配置。
综上所述，本公开实施例的紧耦合处理方法，应用于eNB，在紧耦合场景下eNB和gNB之间建立X2/Xn接口后，eNB发送第一小区与第二小区之间的关联信息至gNB，通知gNB请求的gNB下小区和eNB下小区间的对应，使得后续为UE更为准确地确定目标SCG CELL，降低了处理的差错率。
如图5所示，本公开实施例的一种紧耦合处理方法，应用于第二基站，包括：
S501，接收第一基站发送的第一小区与第二小区之间的关联信息；其中，
所述第一小区为归属于第一基站的小区，所述第二小区为第一基站请求的，且归属于第二基站的小区。
该实施例中，第二基站(即gNB)通过接收第一基站(即eNB)发送的第一小区与第二小区之间的关联信息，就能够了解到eNB的小区和自身小区中eNB请求的小区的对应关系，使得后续为UE更为准确地确定目标SCG CELL。
可选地，所述接收第一基站发送的第一小区与第二小区之间的关联信息的步骤，包括：
接收携带有所述关联信息的EN-DC Configuration update消息；或者
