具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本申请实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
实施例一：
为了减少在终端上下文通过Xn接口传递时，目标侧基站对于是否上报终端与核心网感兴趣区域的关系的判断并减少相应的上报开销，本实施例提供一种位置信息处理方法，该位置信息处理方法应用于源侧基站，请参见图1，该方法包括：
S101、获取第一位置关系信息；
应当说明的是，第一位置关系信息为源侧基站最后一次上报给移动性管理网元的位置关系信息。
S102、将第一位置关系信息发送给目标侧基站，以供目标侧基站根据接收到的第一位置关系信息决定是否将第二位置关系信息上报至移动性管理网元；
应当说明的是，第二位置关系信息为终端切换至目标侧基站后第一次获取的位置关系信息。
其中，位置关系信息包括目标终端的终端位置与核心网感兴趣区域之间的关系，该目标终端可以是任一个终端上下文通过Xn接口发生迁移的终端。可以理解的是，本实施例的位置 信息处理方法应用于源侧基站，源侧基站可以直接取得其曾经向移动性管理网元上报的信息，也即源侧基站可以获取到第一位置关系信息。
例如包括但不限于终端发生站间Resume(即终端启动resume流程接入其他基站)、站间Rnau(Radio AccessNetwork based notification Area Update，无线接入网通知区域更新，以下简称为Rnau)或站间重建立流程的过程中，终端上下文通过Xn接口传递。目标侧基站获取到终端上下文后，目标侧基站若需要根据目标终端在源侧基站时的终端位置与核心网感兴趣区域之间的关系判断是否向移动性管理网元上报位置关系信息，则能够通过上述方法发送的第一位置关系信息直接进行判断，而无需自行进行复杂的逻辑判断，并且能够使得判断结果准确，不存在无法判断的情况，从而减少了目标侧基站向移动性管理网元上报的次数，在一些实施过程中有利于减少上报的开销(例如信令开销)。
在一些实施例中，上述步骤S102包括：在Xn接口中增加位置关系信元，该位置关系信元标识第一位置关系信息；将位置关系信元发送至目标侧基站。通过在接口中增加信元的方式，使得位置关系信息可以通过接口进行传输。相应的，对于目标侧基站而言，其应当对应的作出相应的适配，以Xn接口中获取到该位置关系信元，并基于该位置关系信元了解到实际的第一位置关系信息。
在一些实施例中，上述将位置关系信元发送至目标侧基站包括：在目标信令中携带所述位置关系信元。应当注意的是，该目标信令包括源侧基站在终端上下文切换过程中，需要发送至目标侧基站的信令，例如包括但不限于RETRIEVE UE CONTEXT RESPONSE信令(一种取回终端上下文响应的信令)和/或HANDOVER REQUEST信令(一种移交请求信令)，通过这些信令，将位置关系信元携带到目标侧基站中，从而便于目标侧基站在获得终端上下文后执行判断。
本申请实施例提供的位置信息处理方法，通过获取第一位置关系信息，将所述第一位置关系信息发送给目标侧基站，以供所述目标侧基站根据接收到的所述第一位置关系信息决定是否将第二位置关系信息上报至移动性管理网元，避免了目标侧基站无法准确获知目标终端的终端位置与核心网感兴趣区域之间的关系而消耗多余的资源进行判断和不必要的上报开销；简化了目标侧基站在终端上下文发生Xn接口迁移时对于是否上报终端位置与核心网感兴趣区域之间的关系的判断逻辑，并在一些实施过程中节省不必要的上报开销，有利于减少资源和性能的消耗。
本实施例还提供一种位置信息上报方法，该位置信息上报方法应用于目标侧基站，请参见图1，包括：
S201、接收到其他设备发送的的第一位置关系信息；
应当说明的是，第一位置关系信息为源侧基站最后一次上报给移动性管理网元的位置关系信息。
可以理解的是，本步骤中的其他设备是包括源侧基站在内的其他设备，本实施例中并不限制其他设备的类型，如上所示其可以是同样为基站的源侧基站，在其他实施方式中，也可能为其他网络设备。
S202、若接收到的第一位置关系信息和第二位置关系信息满足预定条件，则将第二位置关系信息上报至移动性管理网元。
应当说明的是，第二位置关系信息为目标终端切换至目标侧基站后第一次获取的位置关系信息。
其中，位置关系信息包括目标终端的终端位置与核心网感兴趣区域之间的关系。可以理解的是，本实施例的位置信息处理方法应用于目标侧基站，目标侧基站可以获取到其上报的第二位置关系信息。
可以理解的是，由于目标侧基站接收到其他设备发送的第一位置关系信息，能够直接根据第一位置关系信息决定是否进行上报，避免了无法准确获知终端位置与核心网感兴趣区域的关系而导致不必要的上报的情况，可见本实施例的位置信息上报方法，能够节省不必要的信息上报开销。
一些实施方式中，位置信息上报方法还包括：
S203、若接收到的第一位置关系信息和第二位置关系信息不满足预定条件，则不将第二位置关系信息上报至移动性管理网元。
可以理解的是，本实施例中，目标侧基站能够获取到的第一位置关系信息能够准确的反映终端位置与核心网感兴趣区域之间的关系，因而对于是否满足预定条件的判断准确，避免产生漏报或不必要的上报的情况。
一些实施方式中，接收到的第一位置关系信息和第二位置关系信息满足预定条件包括：
第二位置关系信息较第一位置关系信息发生变更。也即，若第二位置关系信息较第一位置关系信息发生变更，则将第二位置关系信息上报给移动性管理网元。或者说若判断到目标终端的终端位置与核心网感兴趣区域之间的关系发生改变(源侧基站最后一次上报的与目标侧基站第一次获取的不同)，则目标侧基站将目标终端的终端位置与核心网感兴趣区域之间的关系上报至移动性管理网元,移动性管理网元从而得知了终端位置与核心网感兴趣区域之间的关系的变化。
在一些实施方式中，终端位置与核心网感兴趣区域之间的关系包括但不限于：
终端位置处于核心网感兴趣区域内；
终端位置不处于核心网感兴趣区域内；
无法判定终端位置是否处于核心网感兴趣区域内。
一些实施过程中，基站获取的终端位置为一个确切的位置时，能够准确的与核心网感兴 趣区域进行比较，并判断出终端位置是否处于核心网感兴趣区域内。还在一些实施过程中，基站获取的终端位置为一个范围，例如当终端处于RRC(Radio Resource Control，无线资源控制层)Inactive(不激活)态时，终端可以在RNA(Radio AccessNetwork based Notification Area，无线接入网通知区域，简称RNA)区域内移动而不用通知NG-RAN；基于该终端位置可能的范围的情况，终端位置与核心网感兴趣区域之间的关系可能无法判定。具体的，若核心网感兴趣区域没有完全包括终端位置的范围，则此时，终端位置有可能处于核心网感兴趣区域内，也可能不处于核心网感兴趣区域内，因而无法判定终端位置是否处于核心网感兴趣区域内；若核心网感兴趣区域完全包括了终端位置的范围或终端位置的范围完全不在核心网感兴趣区域中，即此时能够判定出终端位置处于核心网感兴趣区域内或终端位置不处于核心网感兴趣区域内。
在这些实施方式中，无论上述终端位置与核心网感兴趣区域之间的关系如何，只要第一位置关系信息与第二位置关系信息不同(即目标终端的终端位置与核心网感兴趣区域之间的关系发生了变更)，则目标侧基站将目标终端的终端位置与核心网感兴趣区域之间的关系上报至移动性管理网元。
在一些实施方式中，将当前的终端位置与核心网感兴趣区域的关系上报给移动性管理网元包括：通过N2接口的信令将当前的终端位置与核心网感兴趣区域的关系上报给移动性管理网元。作为一种具体的示例，可通过N2接口(接入网与移动性管理网元之间的网络接口)的LOCATION REPORT信令(一种进行位置报告的信令)将终端位置与核心网感兴趣区域的关系上报给移动性管理网元。根据本实施例以上所述，N2接口并不会产生不必要的信令开销。
本申请实施例提供的位置信息上报方法，通过接收到其他设备发送的的第一位置关系信息，根据接受到的第一位置关系信息决定是否将第二位置关系信息上报到移动性管理网元，避免了目标侧基站无法准确获知目标终端的终端位置与核心网感兴趣区域之间的关系而消耗多余的资源进行判断和不必要的上报开销；简化了目标侧基站在终端上下文发生Xn接口迁移时对于是否上报终端位置与核心网感兴趣区域之间的关系的判断逻辑，并在一些实施过程中节省不必要的上报开销，减少资源和性能的消耗。
实施例二：
为了便于对本申请实施例的位置信息处理方法和位置信息上报方法的理解，本实施例中首先对一些技术方案中的位置信息和终端相对于核心网感兴趣的区域的位置关系的处理和上报过程进行说明。在一些技术方案中，一些情况下源侧基站将位置上报信息携带到目标侧基站，例如移动性管理网元向基站下发过终端的位置上报请求，且携带的类型为UE presence in the area of interest，则在终端上下文通过Xn接口迁移时，源侧基站通过XN RETRIEVE UE  CONTEXT RESPONSE信令中的Location Reporting Information信元将位置上报信息携带到目标侧基站。
在一些技术方案中，源侧基站并不会将最新的一次上报的终端相对于核心网感兴趣的区域的位置关系告知目标侧基站，因而目标侧基站基于其能够获取到的源侧基站的相关信息进行自行判断。一些技术方案中目标侧基站判断源侧基站最新上报的终端相对于核心网感兴趣的区域的位置关系的过程可包括以下情况：
情况一：核心网感兴趣的区域仅包括跟踪区标识列表(Tracking Area Identity List，简称TAI List)中的区域，则目标侧基站能够自行判断出源侧基站最新上报的终端相对于核心网感兴趣的区域的位置关系。
情况二：核心网感兴趣的区域包括跟踪区标识列表中的区域，以及5G无线接入网小区全球标识列表(NG-Radio Access NetworkCell Global Identity List，简称NG-RAN CGI List)或者全球无线接入网节点标识列表(Global RAN Node ID List)。在该情况下，目标侧基站判断终端在源侧基站的跟踪区标识相对于核心网感兴趣的跟踪区标识列表的关系，若目标侧基站判断到终端在源侧基站的跟踪区标识在核心网感兴趣的跟踪区标识列表中，则能够判断到终端在源侧基站时相对于核心网感兴趣的区域的位置关系是处于核心网感兴趣的区域中；否则，目标侧基站无法判断出终端在源侧基站时相对于核心网感兴趣的区域的位置关系是如何。
情况三：核心网感兴趣的区域仅包括5G无线接入网小区全球标识列表或者全球无线接入网节点标识列表，则目标侧基站在此种情况下完全无法判断出终端在源侧基站时相对于核心网感兴趣的区域的位置关系。
一些技术方案中，若终端相对于核心网感兴趣的区域的位置关系发生了变更，则目标侧基站向移动性管理网元(核心网侧)上报终端的位置的相关信息(通常通过N2信令LOCATION REPORT上报)，可以理解的是，若没有发生变更，则可以不进行上报。
当目标侧基站面临包括但不限于上述的各种情况时，若无法自行判断出当前的终端相对于核心网感兴趣的区域的位置关系是否较源侧基站最新的一次上报的位置关系发生了变更，则目标侧基站只能通过向核心网上报N2信令LOCATION REPORT以避免漏报。可见，一些技术方案中，为了避免终端的位置的相关信息(包括终端位置与核心网感兴趣区域的关系)的漏报，目标侧基站进行了繁琐的判断过程，并且在无法自行判断的时候只能直接进行终端的位置的相关信息的上报，在一些过程中(例如终端相对于核心网感兴趣的区域的位置关系实际未变更，但目标侧基站无法自行判断是否发生了变更)形成了不必要的N2信令开销。
下面以一种较为具体的实施过程对发明本实施例提供的位置信息处理方法以及位置信息上报方法进行进一步说明。
在本实施例中，于Xn接口中新增位置关系信元。作为具体的示例，本实施例中将位置关系信元命名为UE Presence，在本示例中，UE Presence信元包括在Area of Interest Information信元中，如下表1，示出了本示例中的Area of Interest Information信元的组成结构(本示例中新增了UE Presence信元)，其中，UE Presence信元的信元类型为枚举类型，且取值范围包括in、out和unknown，分别对应了终端位置处于核心网感兴趣区域内、终端位置不处于核心网感兴趣区域内以及无法判定终端位置是否处于核心网感兴趣区域内。

Figure PCTCN2021132127-appb-000002
在终端上下文通过Xn接口迁移时，源侧基站执行的位置信息处理方法包括：
S301、获取第一位置关系信息；
S302、用位置关系信元标识第一位置关系信息并通过目标信令携带位置关系信元；
该目标信令包括源侧基站在终端上下文切换过程中，需要发送至目标侧基站的信令，例如包括但不限于RETRIEVE UE CONTEXT RESPONSE信令和/或HANDOVER REQUEST信令。
作为一种具体示例，源侧基站通过RETRIEVE UE CONTEXT RESPONSE信令和/或HANDOVER REQUEST信令将UE Presence信元最终发送到目标侧基站。具体的，上述Area of Interest Information信元包括在RETRIEVE UE CONTEXT RESPONSE信令或HANDOVER REQUEST信令的Location Reporting Information信元中。如果位置上报类型为report UE moving presence into or out of the Area of Interest，则可将源侧基站最后一次上报给移动性管理网元的目标终端的终端位置与核心网感兴趣区域之间的关系填入UE Presence信元，最终使得目标侧基站能够得知该关系。
而目标侧基站执行的位置信息上报方法包括：
S401、接受源侧基站发送的第一位置关系信息；
本示例中，第一位置关系信息被UE Presence信元标识，以UE Presence信元发送到达目标侧基站，目标侧基站从UE Presence信元的值就能够得知第一位置关系信息，即获知源侧基站最后一次上报给移动性管理网元的目标终端的终端位置与核心网感兴趣区域之间的关系。
S402、当判断到第二位置关系信息较第一位置关系信息发生变更，则通过N2接口的LOCATION REPORT信令上报第二位置关系信息；
第二位置关系信息包括终端切换至所述目标侧基站后第一次获取的目标终端的终端位置与核心网感兴趣区域之间的关系。
若判断到第二位置关系信息与第一位置关系信息相同，即没有发生变更，则不上报第二 位置关系信息。
可以理解的是，若目标侧基站(当终端完成切换后变为终端新的源侧基站)在后续的工作过程中，终端上下文需要迁移到下一个目标侧基站，则其同样可以作为源侧基站执行上述位置信息处理方法。可见，本申请实施例的位置信息处理方法和位置信息上报方法可被同一设备根据实际情况执行。
请参见图3，还示出了一种基站对于RRC-Inactive态终端进行位置上报的时序图。
当终端处于RRC-Inactive态时，如果收到核心网下发的N2接口的LOCATION REPORTING CONTROL信令，且其中携带的Event Type(事件类型)为UE presence inthe area of interest，RAN(Radio Access Network，无线接入网，简称RAN)侧判断终端所在的RNA与核心网感兴趣区域的关系，并进行上报。当终端发生RNAU时，RAN侧会判断终端位置与核心网感兴趣区域的关系，如与最近一次上报的结果不同，则进行上报。在其他示例中，进行包括但不限于站间Resume或站间重建立流程等过程时也可相应判断并在判断到终端位置与核心网感兴趣区域的关系变更后进行上报。
在一些技术方案中，当终端发生站间Resume或站间Rnau时，目标侧基站无法得知源侧基站最后一次上报给移动性管理网元的位置关系信息是基于RNA判断的还是通过准确的位置信息判断的，目标侧基站需要经过复杂的逻辑判断，且可能无法判断出位置关系信息。而在本实施例的示例中，目标侧基站不必关系源侧基站所经历的其他流程，能够直接获取到源侧基站最后一次上报给移动性管理网元的位置关系信息，目标侧基站只需要对其获取的第二位置关系信息与接收到第一位置关系信息比较。
可见，本实施例示例中，仅需要目标侧基站以终端在目标侧基站的终端位置与核心网感兴趣区域之间的关系与上一次上报给移动性管理网元的结果(即源侧基站最后一次上报给移动性管理网元的目标终端的终端位置与核心网感兴趣区域之间的关系)进行比较，即可判断出是否需要进行终端位置与核心网感兴趣区域之间的关系的上报，判断的逻辑简化，并且避免了不必要的上报开销(如本示例中减少了N2接口LOCATION REPORT信令开销)。
实施例三：
本实施例还提供了一种基站设备，参见图4所示，其包括处理器41、存储器42及通信总线43，其中：
通信总线43用于实现处理器41和存储器42之间的连接通信；
处理器41用于执行存储器42中存储的一个或者多个计算机程序，以实现如实施例一和实施例二中的位置信息处理方法步骤，和/或，实现如实施例一和实施例二中的位置信息上报方法步骤。
本实施例还提供了一种计算机存储介质，该计算机存储介质包括在用于存储信息(诸如计算机可读指令、数据结构、计算机程序模块或其他数据)的任何方法或技术中实施的易失性或非易失性、可移除或不可移除的介质。计算机存储介质包括但不限于RAM(Random Access Memory，随机存取存储器),ROM(Read-Only Memory，只读存储器),EEPROM(Electrically Erasable Programmable read only memory，带电可擦可编程只读存储器)、闪存或其他存储器技术、CD-ROM(Compact Disc Read-Only Memory，光盘只读存储器)，DVD(digital versatile disc，数字多功能盘)或其他光盘存储、磁盒、磁带、磁盘存储或其他磁存储装置、或者可以用于存储期望的信息并且可以被计算机访问的任何其他的介质。
本实施例中的计算机存储介质可用于存储一个或者多个计算机程序，其存储的一个或者多个计算机程序可被处理器执行，以实现如实施例一和实施例二中的位置信息处理方法步骤，和/或，实现如实施例一和实施例二中的位置信息上报方法步骤。
对于基站而言，其属于源侧基站还是目标侧基站是一个动态的概念，对于目标终端而言，当前所接入的基站即是源侧基站，将要切换至的基站即是目标侧基站，而当切换完成后，目标侧基站即成为了新的源侧基站。因而可以理解的是，本申请实施例中的计算机存储介质所存储的计算机程序被执行后，可以实现本申请实施例中的位置信息处理方法，也可以实现发明实施例中的位置信息上报方法。
根据本申请实施例提供的位置信息处理、上报方法、基站设备及计算机存储介质，通过获取第一位置关系信息，第一位置关系信息为源侧基站最后一次上报给移动性管理网元的位置关系信息，将第一位置关系信息发送给目标侧基站，以供目标侧基站根据接收到的第一位置关系信息决定是否将第二位置关系信息上报至移动性管理网元，第二位置关系信息为目标终端切换至目标侧基站后第一次获取的位置关系信息；位置关系信息为目标终端的终端位置与核心网感兴趣区域之间的关系，在某些实施过程中可实现包括但不限于的具有简化终端上下文迁移后目标侧基站判断是否上报位置关系信息的判断逻辑，减少上报开销的技术效果。
可见，本领域的技术人员应该明白，上文中所公开方法中的全部或某些步骤、系统、装置中的功能模块/单元可以被实施为软件(可以用计算装置可执行的计算机程序代码来实现)、固件、硬件及其适当的组合。在硬件实施方式中，在以上描述中提及的功能模块/单元之间的划分不一定对应于物理组件的划分；例如，一个物理组件可以具有多个功能，或者一个功能或步骤可以由若干物理组件合作执行。某些物理组件或所有物理组件可以被实施为由处理器，如中央处理器、数字信号处理器或微处理器执行的软件，或者被实施为硬件，或者被实施为集成电路，如专用集成电路。
此外，本领域普通技术人员公知的是，通信介质通常包含计算机可读指令、数据结构、计算机程序模块或者诸如载波或其他传输机制之类的调制数据信号中的其他数据，并且可包括任何信息递送介质。所以，本申请不限制于任何特定的硬件和软件结合。
以上内容是结合具体的实施方式对本申请实施例所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
