- This embodiment describes a scenario in which Ng-eNB and gNB are connected to 5GC, and the topological relationship is shown in FIG. 9.
- OMC configures some basic configuration information on the gNB side for the Ng-eNB side, including TAC, cell ID, etc.
- the Ng-eNB includes three sectors 1, 2 and 3.
- gNB also contains three sectors, sectors 10, 11 and 12. Among them, the Ng-eNB and the gNB are in the same coverage area, so the three pairs of sectors have a neighboring relationship with each other. But OMC determined that there is no Xn interface between the two base stations.
- the corresponding flow diagram is shown in Figure 10.
- the Ng-eNB determines the no Xn attribute between it and the gNB according to the network management configuration, so in this scenario, the Ng-eNB and the gNB cannot establish an interface between the base stations.
- the Ng-eNB lacks the measurement configuration information of the gNB, so the Ng-eNB triggers the measurement information exchange process with the gNB.
- the Ng-eNB is based on the LTE air interface and the connected core network is only 5GC, so it is determined that the interactive information needs to be sent to the AMF through the NG interface.
- step 23 the Ng-eNB determines the content of the interactive information, and sends an Uplink RAN Configuration Transfer (Uplink RAN Configuration Transfer) message to the AMF through the NG interface.

- step 24 after the AMF receives the Uplink RAN Configuration Transfer, it determines that the target cell is within the coverage of the MME and the target is an NR type base station according to the Target gNB ID and TAI in the message, so the interaction message cannot be sent to other core network entities. According to the gNB ID and TAI information in the routing information, the AMF determines the target base station where the interactive information is sent, and sends the downlink RAN configuration transfer (Downlink RAN Configuration Transfer) information to the gNB through the NG interface.
- the information carried in this message includes:

- step 28 after the AMF receives the Uplink RAN Configuration Transfer information sent by the gNB, it determines that the Ng-eNB is within its coverage area according to the Ng-eNB identification information in the routing information, so there is no need to route the interaction information to other core networks. According to the Target Ng-eNB base station identifier and TAI information in the routing information, the AMF determines the target base station for sending the interactive information, and sends the Downlink RAN Configuration Transfer information through the NG interface.

- the Ng-eNB and the gNB are in the same coverage area, so the three pairs of sectors have a neighboring relationship with each other.
- OMC determined that there is no Xn interface between the two base stations. The corresponding process is shown in Figure 12.
- step 31 the Ng-eNB determines the no Xn attribute between it and the gNB according to the network management configuration, so in this scenario, the Ng-eNB and the gNB cannot establish an interface between the base stations.

本申请是以CN申请号为201910523863.X,申请日为2019年6月18日的申请为基础,并主张其优先权,该CN申请的公开内容在此作为整体引入本申请中。
本公开涉及无线通信领域,特别涉及一种异系统测量信息传输方法和系统、计算机可读存储介质。
5G作为下一代无线网络的主要技术,具有支持超宽带、大连接等技术特征。在相关技术中,有以下几种主流的组网架构和接口情况:
·在EN-DC(E-UTRA NR,演进的通用陆地无线接入网络双连接)组网场景中,en-gNB(EN-DC组网方式下的新空口NR基站)与eNB(演进基站)之间采用X2接口进行连接。在该场景中,仅由eNB维护到EPC(Evolved Packet Core,演进的分组核心网)的S1-C接口,en-gNB在支持SCG(Secondary Cell Group,辅小区组)分割(Split)承载或SCG承载时需支持到EPC的S1-U接口。
·相对于以往几代无线技术,5G中支持两种类型的无线接入基站,即基于新空口的基站和基于LTE演进的Ng-eNB(Next Generation eNodeB,下一代演进基站),这两种类型的基站都连接到5G的核心网5GC中。其中基站间通过Xn接口进行连接,基站与5G核心网之间通过NG接口进行连接。
在SA(Standalone,独立组网)的场景中,有以下两种场景gNB和eNB或者Ng-eNB之间是没有基站间接口。
·场景1:当gNB和LTE(Long Term Evolution,长期演进)eNB分别连接到各自的核心网,即gNB连接5GC而eNB连接到EPC中时,gNB和eNB之间不支持基站间接口的建立。
·场景2:gNB和Ng-eNB连接到5GC中,由于不是相同设备或者两个基站位于不同省的区域边界上等原因,无法建立Xn接口。
在目前的5G协议中,针对一个NR空口的小区或者频点,如下信息可以帮助UE 更快的完成目标小区同步及后续的测量操作。
·小区所在载波的数据和SSB(Synchronization Signal Block,同步信号块)的SCS(Subcarrier Spacing,子载波间隔)信息:目前在6GHz以下支持15KHz,30KHz及60KHz等多种,并且数据和SSB的SCS原则上是可以不同的。例如在6GHz以上的频率中,一个载波可以支持多个SSB,且不同SSB可以配置不同的SCS。
·SMTC(SSB Measurement Timing Configuration,基于SSB的测量时间配置)信息:指示了该小区中需要测量的SSB的位置信息。终端需要根据SMTC的配置信息确定需要测量的SSB的位置和个数。
而对于一个LTE的载波和小区,如下信息可以帮助终端更快的完成目标小区同步及后续的测量操作:
·子帧配置情况情况:对于TDD(Time Division Duplex,时分双工)系统包括子帧配置以及特殊时隙配置情况。
·天线端口数:在LTE系统中CRS(Cell Reference Signal,小区参考信号)测量通常支持1端口,2端口或者4端口等三种情况,其中对于一些时分的站点或者小区通常仅支持单端口的信号发送。

发明人注意到,由于在目前的5G规范中,在gNB和eNB之间没有接口的情况下,导致异系统测量面临如下问题:
·无法获取必要的测量配置信息:eNB缺少SMTC和SSB等参数,而gNB缺少TD-LTE帧结构,因此终端测量时仅能根据载波的默认参数进行测量,则异系统测量时延较大,影响终端的切换。
·缺少交互的手段:无论S1或者NG接口中的SON信息交互方案,都缺乏跨EPC和5GC的交互场景,且目前的SON信息缺少测量配置交互。
·跨核心网缺少寻址信息:无论S1或者NG接口中的SON信息交互方案,缺少跨核心网的寻址信息和方案,无法EPC和/或AMF将正确配置信息路由到正确的核心网实体或者基站节点。
为此,本公开提供一种eNB和gNB在没有基站间接口的时候可以自动获取测量配置信息的方案。
图1为本公开一个实施例的异系统测量信息传输方法的流程示意图。
在步骤101,第一基站根据预配置信息,判断在第一基站和第二基站之间是否有直接进行通信的接口。
在一些实施例中,预配置信息为OMC(Operation and Maintenance Center,操作维护中心)配置信息或者终端ANR(Automatic Neighbor Relation,自动邻区关系)测量上报信息。
OMC配置信息包括第一基站和第二基站的邻区关系,邻区关系包括第二基站的小区PCI(Physical Cell Identifier,物理小区标识符)、小区标识、TAC(Tracking Area Code,跟踪区码)配置(2字节、3字节或者二者都有)、小区无线类型(仅支持SA、NSA或者支持双模)和模式信息、以及是否设置禁止使用预定接口(例如X2或Xn)的指示信息中的至少一项。
终端ANR测量上报信息包括第一基站范围内的终端所上报的与第二基站相关的小区的PCI、小区标识、TAC配置、小区无线类型和模式信息中的至少一项。
在一些实施例中,在预配置信息为OMC配置信息的情况下,第二基站提供测量配置的小区由OMC配置的第二基站邻区列表信息确定。在预配置信息为终端ANR测量上报信息的情况下,第二基站提供测量配置的小区为与第二基站相关联的全部小区。
图2为本公开一个实施例的基站间接口判断方法的流程示意图。如图2所示,上述第一基站根据预配置信息,判断在第一基站和第二基站之间是否有直接进行通信的接口包括:
在步骤201,第一基站根据预配置信息,判断第一基站和第二基站是否属于不同的无线类型。
若第一基站和第二基站属于不同的无线类型,则进一步执行步骤202;否则结束本流程。
在步骤202,判断第一基站和第二基站是否均设置禁止使用预定接口。例如,判断第一基站和第二基站是否均设置no X2或no Xn属性。
若第一基站和第二基站均设置禁止使用预定接口,则执行步骤205;否则执行步骤203。
在步骤203,判断是否第二基站的无线类型为NR且采用SA模式、第一基站的无线类型为LTE且仅连接到EPC。
若第二基站的无线类型为NR且采用SA模式、第一基站的无线类型为LTE且仅连接到EPC,则执行步骤205;否则执行步骤204。
在步骤204,判断是否第二基站的无线类型为LTE且TAC有预定格式、第一基站的无线类型为NR且采用SA模式。例如,判断TAC是否仅有2字节格式。
若第二基站的无线类型为LTE且TAC有预定格式、第一基站的无线类型为NR且采用SA模式,则执行步骤205;否则结束本流程。
在步骤205,判定第一基站和第二基站之间没有直接进行通信的接口。
这里需要说明的是,在其它情况下则认为第一基站和第二基站之间存在基站间接口,其相关的交互流程不是本公开的发明点所在。
返回图1,在步骤102,若第一基站和第二基站之间没有直接进行通信的接口,第一基站根据自身配置确定对应的核心网,以及第一基站与对应的核心网之间的接口。
在一些实施例中,若第一基站的无线类型为LTE且第一基站仅连接第一核心网, 其中第一核心网为EPC,则将第一核心网作为对应的核心网,将S1接口作为第一基站与第一核心网之间的接口。若第一基站的无线类型为LTE且第一基站仅连接第二核心网,其中第二核心网为5GC,则将第二核心网作为对应的核心网,将NG接口作为第一基站与第二核心网之间的接口。若第一基站的无线类型为LTE且第一基站分别连接第一核心网和第二核心网,其中第一核心网为EPC,第二核心网为5GC,则将第二核心网作为对应的核心网,将NG接口作为第一基站与第二核心网之间的接口。若第一基站的无线类型为NR,则将第一核心网作为对应的核心网,其中第一核心网为5GC,将NG接口作为第一基站与第一核心网之间的接口。

在一些实施例中,第二基站在接收到第一测量配置信息后,保存第一路由信息、第一基站的测量配置信息和第二核心网的控制面实体的标识。
在一些实施例中,在第一基站的无线类型为NR的情况下,第二基站根据测量配置信息中的频点信息确定NR绝对射频信道号ARFCN-ValueNR,根据SSB的SCS配置信息确定SSB子载波间隔ssbSubcarrierSpacing,根据SMTC信息确定测量参数smtc1。在第一基站的无线类型为LTE的情况下,第二基站根据端口数和频点确定终端测量的小区参考信号CRS的当前天线端口个数PresenceAntennaPort1和EUTRA绝对射频信道号ARFCN-ValueEUTRA,根据子帧配置确定r10测量子帧样式MeasSubframePattern-r10参数。

图3为本公开另一个实施例的异系统测量信息传输方法的流程示意图。图3与图1的不同之处在于,在图3所示实施例中,第一基站直接将第一测量配置信息发送给第二核心网的控制面实体。
在步骤301,第一基站根据预配置信息,判断在第一基站和第二基站之间是否有直接进行通信的接口。
在步骤302,若第一基站和第二基站之间没有直接进行通信的接口,第一基站根据自身配置确定对应的核心网,以及第一基站与对应的核心网之间的接口。
在步骤303,若对应的核心网为与第二基站相对应的第二核心网,第一基站通过第一基站与第二核心网之间的接口,将第一测量配置信息发送给第二核心网的控制面实体。
在步骤304,第二核心网的控制面实体利用第二基站与第二核心网之间的接口,将第一测量配置信息转发给第二基站。
在步骤305,第二基站根据第一测量配置信息,确定第二基站覆盖范围内的终端针对第一基站的异系统测量配置信息。
图4为本公开又一个实施例的异系统测量信息传输方法的流程示意图。第二基站根据来自第一基站的第一测量配置信息确定第二基站覆盖范围内的终端针对第一基站的异系统测量配置信息之后,还执行以下步骤。

在步骤403,第二核心网的控制面实体判断第一基站是否在第二核心网的控制面实体中注册。
在步骤404,若第一基站未在第二核心网的控制面实体中注册,则第二核心网的控制面实体利用核心网间接口,通过第二核心网间交互信息将第二测量配置信息发送给第一核心网的控制面实体,其中第一基站在第一核心网的控制面实体中注册。
在一些实施例中,第二核心网间交互信息包括:

下面通过具体实施例对本公开所提供的方案进行说明。
实施例一:
本实施例描述eNB连接到EPC,gNB连接到5G核心网5GC的场景。5GC和MME之间存在N26接口,其拓扑关系如图7所示。OMC在eNB侧配置关于gNB侧的一些基本配置信息,包括TAC、小区ID等。eNB包括三个扇区1、2和3。gNB也 包含了三个扇区,扇区10、11和12。eNB和gNB之间是同覆盖区域,因此三对扇区之间互为邻区关系。相应的流程示意图如图8所示。
在步骤11,eNB根据gNB的TAC信息和模式信息确定gNB是一个仅支持SA模式的基站,并且仅连接到5GC。由于eNB自身仅连接到EPC,因此在该场景中eNB和gNB之间无法建立的直接进行通信的接口。
在步骤12,由于eNB缺少gNB的测量配置信息,因此eNB触发了与gNB之间的测量信息交互过程。eNB根据其为支持LTE空口,且连接的核心网仅为EPC,因此eNB确定交互信息需要通过S1接口发送给MME。
在步骤13,eNB确定交互信息的内容,并且通过S1接口发送eNB配置传送(eNB Configuration Transfer)消息给MME。其中该消息中携带的信息为:
·路由信息,包括如下:

在步骤14,MME收到eNB Configuration Transfer消息后,根据消息中的Target gNB ID和TAI确定目标小区不在MME覆盖范围内且目标是一个NR类型的基站,因此需要将该消息通过N26接口转发给TAI所关联的核心网实体AMF。转发消息包括如下内容:

■目的基站所选择的TAI(Selected TAI):其中TAC信息为2byte长度
·gNB中三个小区的测量配置信息:每个小区测量信息包括:小区的频点、PCI和小区标识,SMTC和SSB的SCS信息
在步骤19,AMF收到gNB发送的Uplink RAN Configuration Transfer后,根据路由信息中eNB标识信息确定eNB不连接到AMF中,需要将该交互信息路由到其他核心网,并根据路由信息中的TAI,确定与上述TAI关联的MME及核心网间接口N26。AMF向MME转发消息的具体内容为:
·AMF实体标识
·路由信息,包括如下:
■源基站标识(Source eNB ID):长度为32比特
■源基站所选择的TAI(Selected TAI):其中TAC信息为3byte长度
