Description

一种信令交互方法、基站及装置
相关申请的交叉引用
本申请要求在2019年01月31日提交中国专利局、申请号为201910095596.0、申请名称为“一种信令交互方法、基站及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，特别涉及一种信令交互方法、基站及装置。
背景技术
下面先对RAN(Radio Access Network，无线接入网)侧架构进行简单说明。
eNodeB(Evolution NodeB，演进基站)和gNB(next generation NodeB，下一代基站)的tight interworking(紧耦合)的场景下，主要有如下两种情况，其中第二种场景也包含了NR(next generation Radio，下一代无线)-NR DC(Next generation Radio Dual Connectivity，下一代无线通信双连接)。
A)LTE(Long Term Evolution，长期演进)是主基站，5G节点为辅基站的场景，通过LTE基站连接到核心网。图1为连接到EPC(Evolved Packet Core，演进分组核心网)的eNodeB和gNB tight interworking架构示意图，具体如图1所示。
B)5G节点和LTE基站都连接到5G的CN(Core Network，核心网)，图2为连接到5GC的eNodeB和gNB tight interworking以及NR-RN DC架构示意图，具体如图2所示。
图3为切换过程中增加双连接的流程示意图，图中涉及本申请的步骤分别为：13.Data Forwarding(数据前送)、16a.New Path(split/MCG bearer)(新 路径(拆分/MCG承载)，MCG：Master Cell Group，主小区组)、16b.New Path(split/SCG bearer)(新路径(拆分/SCG承载))如图所示，目标基站在收到源基站的切换请求消息后，根据切换请求消息中携带的承载信息决定是否需要建立双连接。如果需要建立双连接而且有合适的SCG(Secondary Cell Group，辅小区组)小区，目标MN(Master node，主节点)会向目标SN(Secondary node，辅节点)发起SN addition(SN增加)过程。收到SN的响应后，目标MN向源基站发送切换响应消息。目标MN通过对UE(User Equipment，用户设备)建立双连接来满足UE的吞吐量的需求。
现有技术的不足在于，目前的规范仅支持两个基站之间的load(负载)的交互，也就是说，源基站只能考虑目标基站自身的load决定切换的目标小区，而没有办法考虑目标基站可以在切换过程执行双连接的场景。

可选地，进一步包括：
为切换进的终端建立双连接。
本申请实施例中提供了一种信令交互装置，包括：
收发模块，用于与其他基站交互信息，所述信息中包含与自身有接口的基站的列表和/或与自身有接口的基站下小区的load信息；或者，所述信息中包含load信息，所述load信息是部分地根据本基站下小区的load相关信息和 /或能够为终端建立双连接的与本基站有接口的基站下的小区load信息确定的。
本申请实施例中提供了一种计算机可读存储介质，所述计算机可读存储介质存储有执行上述信令交互方法的计算机程序。
本申请有益效果如下：
在本申请实施例提供的技术方案中，由于能够清楚地在信息交互中，指明那些小区和自己有接口，以及这些小区的load信息，传递的是多个不同的信息。或者，在交互load信息的时候，综合考虑了和自己有接口的小区的信息，只传递一个信息，但综合考虑了其他小区的信息，因而解决了信令交互的问题。
进一步的，由于两个基站之间不仅仅交互自身的load信息，还与为终端建立双连接有关的信息。这样，在源基站选择切换的目标小区的时候，不仅仅考虑相邻基站自身的load，还考虑相邻基站是否可以为UE建立双连接，从而可以为UE提供更高的速率的服务；或者，由于两个基站交互的load信息综合考虑了自身以及可以与其建立双连接的gNB下的小区的load信息。这样，在切换过程中，根据该信息进行目标基站的选择，更加合理。

图2为背景技术中连接到5GC的eNodeB和gNB tight interworking以及NR-RN DC架构示意图；

具体实施方式
发明人在发明过程中注意到：
在LTE系统中，E-UTRAN由多个eNodeb组成，eNodeB与EPC之间通过S1接口连接，eNodeB之间通过X2接口连接，为了支持更高的数据吞吐量，UE可以通过两个eNodeb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eNodeB和gNB的紧耦合互操作(tight interworking)以及gNB和gNB的双连接。
切换过程中，可以从双连接切换到双连接，也可以从单连接切换到双连接。在源基站发起切换准备之前，源基站需要知道周围邻区的load以确保这次切换不被拒绝。然而，目前的规范仅支持两个LTE基站之间的load的交互，也就是说，源LTE基站只能考虑目标LTE基站自身的load决定切换的目标小区，而没有办法考虑目标基站可以在切换过程执行双连接的场景。基于此，本申请提供了一种信令交互的方案，下面结合附图对本申请的具体实施方式进行说明。
一种信令交互方法，可以包括：
与其他基站交互信息，所述信息中包含与自身有接口的基站的列表和/或与自身有接口的基站下小区的load信息；或者，
所述信息中包含load信息，所述load信息是部分地根据本基站下小区的load相关信息和/或能够为终端建立双连接的与本基站有接口的基站下的小区load信息确定的。
可选地，可以是，与其他基站交互信息，所述信息中包含和自身有接口的基站的列表和/或这些和自身有接口的基站的load信息；或者，交互的load信息是考虑了和本基站有接口，可以为终端建立双连接的基站下的小区load信息。
具体的，第一种方式下，能够清楚地在信息交互中，指明那些小区和自己有接口，以及这些小区的load信息，传递的是多个不同的信息。第二种方式下是在交互load信息的时候，综合考虑了和自己有接口的小区的信息，只 传递一个信息，但综合考虑了其他小区的信息。
在进行考虑时，比如说，虽然自身load比较重，但是，考虑和其有接口的基站load较轻，可以为切换过来的UE建立双连接，在和对端交互load信息的时候，可以给对端提供一个load的综合评估后的值。
在用于切换时，可以按如下方式实施：
图4为切换方法实施流程示意图，如图所示，包括：
步骤401、与其他基站交互信息，所述信息中包括有与为终端建立双连接有关的信息；
步骤402、在为终端选择切换的目标小区时，根据所述信息确定切换的目标小区。
可选地，所述与为终端建立双连接有关的信息包括如下信息之一或者其组合：
基站的load信息、与自身有X2或Xn连接的基站名单、与自身有X2或Xn连接的基站的load信息。
具体可选地，两个基站之间不仅仅交互自身的load信息，还交互哪些基站和自己有X2/Xn连接，以及和自己有X2/Xn连接的基站的load信息。这样，在源基站选择切换的目标小区的时候，不仅仅考虑相邻基站自身的load，还考虑相邻基站是否可以为UE建立双连接，从而可以为UE提供更高的吞吐量。
或者，两个基站交互的load信息综合考虑了自身以及可以与其建立双连接的gNB下的小区的load信息。这样，在切换过程中，根据该信息进行目标基站的选择，可以更加合理。
可选地，与其他基站交互信息，是在建立X2接口或Xn接口后，通过接口信令通知所述信息的。
可选地，在通过X2接口信令与其他基站交互信息时，是通过RESOURCE STATUS UPDATE(资源状态更新)信令通知所述信息的；或者，
在通过Xn接口信令与其他基站交互信息时，是通过Load Status Report(负载状态报告)信令通知所述信息的。
可选地，所述RESOURCE STATUS UPDATE信令中进一步包括IE(Information Element，信息单元)，所述IE用以携带本基站有X2连接且能够进行双连接操作的gNB下的小区名单。
可选地，IE是Neighbor Cell Load Information list(邻小区负载信息列表)。
具体的，为了进一步交互邻区的load信息，可以在该消息中增加新的IE，即Neighbor Cell Load Information list，在该list中，包含和本小区有X2连接可以进行双连接操作的gNB下的小区。
可选地，还可以进一步包括：
为切换进的终端建立双连接。
具体的，考虑到切换过程中，可以在目标侧直接建立双连接，在RESOURCE STATUS UPDATE消息中提供的Radio Resource Status是综合考虑了可以和其建立双连接的gNB下的小区的load。
例如，eNB1下小区的负荷是比较重的状态，如果仅仅考虑本小区的load，是不能作为切换的目标小区了。但是，和eNB1连接的gNB下的小区的负荷比较轻，eNB1可以考虑为切换过来的UE建立双连接。为了达到该目的，即使eNB1下的小区的负荷较重，在通知对端自己的load状态时，也需要通知对端还有更多可用的资源(考虑了和自己相连的gNB下小区的可用资源)。
下面通过实例进行说明。
实施例一：
本例中，两个LTE基站建立X2接口后，通过接口信令通知对端自己的load情况，同时，也通知对端自己和哪些gNB(位于两个LTE基站的overlapping(重叠)区域)有X2连接以及这些gNB的load情况。
目前两个LTE基站之间交互load信息的过程如下，可以参考3GPP(Third generation partnership project，3代合作项目)协议的9.1.2.14部分：RESOURCE STATUS UPDATE(资源状态更新)。
This message is sent by eNB2 to neighbouring eNB1 to report the results of the requested measurements.(此信息由eNB2发送给相邻的eNB1，以报告所 要求的测量结果。)
Direction(方向):eNB2→eNB1.
Figure PCTCN2019127215-appb-000001
Figure PCTCN2019127215-appb-000002
为了进一步交互邻区的load信息，可以在该消息中增加新的IE，即Neighbor Cell Load Information list，在该list中，包含和本小区有X2连接可以进行双连接操作的gNB下的小区。
修改后的消息可以定义如下：
Figure PCTCN2019127215-appb-000003
Figure PCTCN2019127215-appb-000004
实施例二：
本例中，两个LTE基站建立X2接口后，通过接口信令通知对端自己的load情况，在通知对端load情况的时候，综合考虑和自己有X2连接的gNB的load情况。
在实施例1中，给出了两个基站之间交互load信息的过程。考虑到切换过程中，可以在目标侧直接建立双连接，在RESOURCE STATUS UPDATE消息中提供的Radio Resource Status是综合考虑了可以和其建立双连接的gNB下的小区的load。
例如，eNB1下小区的负荷是比较重的状态，如果仅仅考虑本小区的load，是不能作为切换的目标小区了。但是，和eNB1连接的gNB下的小区的负荷比较轻，eNB1可以考虑为切换过来的UE建立双连接。为了达到该目的，即使eNB1下的小区的负荷较重，在通知对端自己的load状态时，也需要通知对端还有更多可用的资源，也即考虑了和自己相连的gNB下小区的可用资源。
实施例三：
本例中，两个连接到5GC的基站建立Xn接口后，通过接口信令通知对端自己的load情况，同时，也通知对端自己和哪些gNB(位于两个基站的overlapping区域)有Xn连接以及这些gNB的load情况。
目前的规范还不支持Xn接口交互load信息，实施中可以在Xn接口引入消息，比如Load Status Report以支持load信息的交互。
消息的定义可以如下所示：
Figure PCTCN2019127215-appb-000005
实施例四：
本例中，两个连接到5GC的基站建立Xn接口后，通过接口信令通知对端自己的load情况，在通知对端load情况的时候，综合考虑和自己有Xn连接的gNB的load情况。
在实施例3中，给出了两个连接到5GC的基站之间交互load信息的过程。考虑到切换过程中，可以在目标侧直接建立双连接，在建议引入的Load Status Report消息中提供的Radio Resource Status是综合考虑了可以和其建立双连接的gNB下的小区的load。
例如，gNB1下小区的负荷是比较重的状态，如果仅仅考虑本小区的load，是不能作为切换的目标小区了。但是，和gNB1连接的gNB下的小区的负荷比较轻，gNB1可以考虑为切换过来的UE建立双连接。为了达到该目的，即使gNB1下的小区的负荷较重，在通知对端自己的load状态时，也需要通知 对端还有更多可用的资源，也即考虑了和自己相连的gNB下小区的可用资源。
基于同一发明构思，本申请实施例中还提供了一种基站、信令交互装置、存储介质，由于这些设备解决问题的原理与信令交互方法相似，因此这些设备的实施可以参见方法的实施，重复之处不再赘述。
在实施本申请实施例提供的技术方案时，可以按如下方式实施。
图5为基站结构示意图，如图所示，基站中包括：
处理器500，用于读取存储器520中的程序，执行下列过程：
与其他基站交互信息，所述信息中包含与自身有接口的基站的列表和/或与自身有接口的基站下小区的load信息；或者，所述信息中包含load信息，所述load信息是部分地根据本基站下小区的load相关信息和/或能够为终端建立双连接的与本基站有接口的基站下的小区load信息确定的；
收发机510，用于在处理器500的控制下接收和发送数据。
可选地，与其他基站交互信息，是在建立X2接口或Xn接口后，通过接口信令通知所述信息的。
可选地，在通过X2接口信令与其他基站交互信息时，是通过RESOURCE STATUS UPDATE信令通知所述信息的；或者，
在通过Xn接口信令与其他基站交互信息时，是通过Load Status Report信令通知所述信息的。
可选地，所述RESOURCE STATUS UPDATE信令中进一步包括IE，所述IE用以携带本基站有X2连接且能够进行双连接操作的gNB下的小区名单。
可选地，所述IE是Neighbor Cell Load Information list。
可选地，进一步包括：
为切换进的终端建立双连接。
其中，在图5中，总线架构可以包括任意数量的互联的总线和桥，具体由处理器500代表的一个或多个处理器和存储器520代表的存储器的各种电路链接在一起。总线架构还可以将诸如外围设备、稳压器和功率管理电路等之类的各种其他电路链接在一起，这些都是本领域所公知的，因此，本文不 再对其进行进一步描述。总线接口提供接口。收发机510可以是多个元件，即包括发送机和收发机，提供用于在传输介质上与各种其他装置通信的单元。处理器500负责管理总线架构和通常的处理，存储器520可以存储处理器500在执行操作时所使用的数据。
本申请实施例中还提供了一种信令交互装置，包括：
收发模块，用于与其他基站交互信息，所述信息中包含与自身有接口的基站的列表和/或与自身有接口的基站下小区的load信息；或者，所述信息中包含load信息，所述load信息是部分地根据本基站下小区的load相关信息和/或能够为终端建立双连接的与本基站有接口的基站下的小区load信息确定的。

为了描述的方便，以上所述装置的各部分以功能分为各种模块或单元分别描述。当然，在实施本申请时可以把各模块或单元的功能在同一个或多个软件或硬件中实现。
综上所述，在本申请实施例提供的技术方案中，给出了在支持双连接的场景下，如何更合理的进行切换判决，即不仅仅考虑对端基站的load，还考虑可以和对端基站进行双连接操作的基站的负荷情况。由于两个基站之间不仅仅交互自身的load信息，还交互哪些基站和自己有X2/Xn连接，以及和自己有X2/Xn连接的基站的load信息。这样，在源基站选择切换的目标小区的时候，不仅仅考虑相邻基站自身的load，还考虑相邻基站是否可以为UE建立双连接，从而可以为UE提供更高的速率的服务。进一步的，由于两个基站交互的load信息综合考虑了自身以及可以与其建立双连接的gNB下的小区的load信息。这样，在切换过程中，根据该信息进行目标基站的选择，更加合理。
