但是，在Non Terrestrial Network(NTN，非地面通信网络)系统中，由于卫星高度很高，处于小区边缘的时候不同的小区所对应的RSRP差异并不明显，因此采用前述同样的RSRP测量以及切换处理的方式会出现终端已经离开原来的服务小区进入另一个小区，却没有及时切换到新的小区，从而导致该终端设备的服务被中断的问题，影响用户体验。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
示例性的，本申请实施例应用的通信系统100可以如图1所示。该通信系统100可 以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的网络设备(Base Transceiver Station，BTS)，也可以是WCDMA系统中的网络设备(NodeB，NB)，还可以是LTE系统中的演进型网络设备(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。

为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
本申请提供的实施例，可以应用于Non Terrestrial Network(NTN，非地面通信网络)中。其中，所述NTN采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为LEO(Low-Earth Orbit，低地球轨道)卫星、MEO(Medium-Earth Orbit，中地球轨道)卫星、GEO(Geostationary Earth Orbit，地球同步轨道)卫星、HEO(High Elliptical Orbit，高椭圆轨道)卫星等等。其中，
LEO，低轨道卫星高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端的发射功率要求不高。
GEO，地球同步轨道卫星，轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖 地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
相关技术中，地面蜂窝网通信比如5G通信系统中，由基站为终端设备配置测量，终端设备上报测量结果，相关的测量结果用于为终端设备配置测量的基站，判断是否对该终端设备执行切换。可就是说，基站收到现有的测量上报后的决策是针对某一个终端设备的。且基站收到测量结果后，该测量结果仅能由本基站使用。
其中，以Xn接口切换过程为例所对应的一种切换处理为例进行说明，整个切换过程分为以下三个阶段，可以参见图2所示，包括：
切换准备阶段：如图中所示的0-5，第二网络设备以及第一网络设备根据访问和移动性管理功能实体(AMF，Access and Mobility Management Function)提供的移动控制信息进行处理；终端设备进行测量控制及上报，第一网络设备进行切换决策，然后由第一网络设备向第二网络设备进行切换请求、管理控制以及切换请求确认。其中，在切换确认消息中包含第二网络设备生成的切换命令，并且不允许第一网络设备对第二网络设备生成的切换命令进行任何修改，直接将切换命令转发给终端设备。
切换执行阶段：如图中6-7所示，终端设备在收到切换命令后立即执行切换过程，可以包括有终端设备与第一网络设备之间进行无线接入网(RAN，Radio Access Network)切换，终端设备断开第一网络设备并与第二网络设备进行同步并建立连接(如执行随机接入，发送RRC切换完成消息给目标基站等)；SN状态转移；还可以包括有第一网络设备传输用户面功能实体(UPF，User Plane Function)的新数据，并且将缓存数据传输至第二网络设备。
切换完成阶段：如图中8-12所示，RAN切换完成之后，终端设备通过第二网络设备之间进行用户数据的传输，并且第二网络设备与UPF之间进行用户数据的传输；然后第二网络设备与AMF发送路径切换请求，由UPF执行路径切换，然后由AMF通过第一网络设备通知第二网络设备路径切换结束，AMF向第二网络设备发送路径切换请求确认，然后第二网络设备通知第一网络设备进行用户数据的释放。
另外，对于某些特殊场景，比如终端设备高速移动或者高频条件下，需要频繁的进行切换。条件切换(CHO，Conditional handover)避免了切换准备时间过长，导致UE要切换的时候已经过晚的问题，为终端设备提前配置切换命令。另一方面，对于高铁场景，终端设备的运行轨迹是特定的，所以基站可以提前把目标基站配给终端设备，并且在HO command中包含用于触发UE进行切换的条件，当满足所配条件时，UE向目标基站发起接入请求。如图3所示，终端设备基于第一网络设备的测量配置进行测量并进行测量上报；第一网络设备与第二网络设备之间完成切换准备后第一网络设备向终端设备发送切换命令，然后终端设备在满足条件的情况下，与第二网络设备进行同步。
在前述相关技术中，比如在NR系统中，终端设备处于小区中心时的参考信号接收功率RSRP要明显高于其处于小区边缘时的RSRP。由于存在明显的“远近效应”，当终端设备移动到小区边缘时，服务小区的信号质量变差，相邻小区的信号质量变好，因此可以基于终端设备对小区的信号质量测量来进行移动性管理，即终端设备可以通过RSRP测量来判断自己是否移动到小区边缘，从而为切换做准备。
但是，在NTN系统中，由于卫星高度很高，如图4所示，对于处于小区中心的终端设备和处于小区边缘的终端设备，他们对应的RSRP差异并不明显，如果使用目前的基于RSRP测量的切换机制，终端设备难以通过RSRP测量来辨别自己是否处于小区边缘，也难以通过RSRP测量来寻找比当前服务小区的信道质量更好的相邻小区，因此会出现终端已经离开原来的服务小区进入另一个小区，却没有及时切换到新的小区，从而导致该终端设备的服务被中断的问题，影响用户体验。
基于此，本申请提供的方案中，避免采用参考信号的测量来进行对NTN场景下的终端进行切换处理。本申请主要通过进行服务小区以及相邻小区的第一距离以及第二距离的测量，来确定是否符合第一条件的要求，如果符合就可以进行后续的切换处理。
需要指出的是，由于终端设备所在的服务小区可以存在一个或多个相邻小区，这里可以将终端设备与每一个相邻小区的中心位置的距离均作为第二距离，或者终端设备针对不同的相邻小区存在有不同的对应的第二距离。本申请提供的方案中，针对每一个相邻小区对应的第二距离的处理是相同的，因此不再重复说明。
具体的，本发明实施例提供了一种切换处理方法，如图5所示，所述方法包括：
步骤21：终端设备获取通信设备配置的第一条件；其中，所述第一条件为基于第一距离以及第二距离确定触发执行由服务小区切换至目标小区的处理的条件；其中，所述第一距离为所述终端设备所在位置与所在服务小区的中心位置之间的距离；所述第二距离为所述终端设备所在位置与相邻小区的中心位置之间的距离；
步骤22：所述终端设备基于第一距离、第二距离，确定是否满足所述第一条件；
步骤23：若满足所述第一条件，则所述终端设备向服务小区的通信设备上报测量结果。
相应的，本实施例提供一种切换处理方法，如图6所示，包括：
步骤31：通信设备为终端设备配置第一条件；其中，所述第一条件为基于第一距离以及第二距离确定触发执行由源小区切换至目标小区的处理的条件；其中，所述第一条件为基于第一距离以及第二距离确定触发执行由服务小区切换至目标小区的处理的条件；其中，所述第一距离为所述终端设备所在位置与所在服务小区的中心位置之间的距离；所述第二距离为所述终端设备所在位置与相邻小区的中心位置之间的距离；所述通信设备为所述终端设备所在的服务小区对应的通信设备；
步骤32：接收所述终端设备上报的测量结果。
前述通信设备可以为卫星。
其中，本申请中的切换处理可以有两种类型，分别为第一类切换处理以及第二类切换处理；
所述第一类切换处理可以为普通切换，也就是终端设备向服务小区的通信设备进行测量结果上报，然后基于通信设备转发的切换命令向目标小区所对应的通信设备发起随机接入进而完成切换；第二类切换可以为终端设备确定目标小区，然后终端设备直接向目标小区的通信设备发起切换的处理。
本实施例主要针对前述第一类切换处理类型进行后续说明。下面分别结合多种示例进行详细说明：
示例1、
本示例中，对于具有定位能力的终端设备，终端设备基于自己到小区地面中心位置之间距离的测量，当终端设备到服务小区(也就是源小区)地面中心位置的第一距离比终端设备到相邻小区地面中心位置的第二距离大于第一门限，并且终端设备到第一距离与第二距离之间差值的变化大于第二门限时，终端设备进行测量上报，触发服务小区的通信设备准备切换。
本示例中，所述第一条件，为：
RRC消息中携带的测量配置中所包含的触发条件；所述测量配置为第一类切换处理中传输的消息；
其中，所述第一类切换为通信设备为终端设备确定目标小区的切换。
其中，所述触发条件，包括：至少一种距离门限值、持续时长。
具体实施过程如下：
1、终端设备通过无线资源控制(RRC，Radio Resource Control)消息向通信设备发送指示信息，用于指示自身是否支持定位功能；其中，所述指示信息可以在终端设备能力消息中。
2、终端设备接收通信设备通过RRC消息发送的测量配置，该测量配置用于配置距离测量的相关参数。
具体地，相关参数可以包括：
配置至少一个测量对象；其中，所述至少一个测量对象中的每个测量对象为一个频率内的NTN载波频率或一个频率间的NTN载波频率。对于每个配置了测量的NTN载波频率，网络可以配置与该载波频率相关的小区偏移量列表，黑名单小区列表和白名单小区列表。其中，黑名单小区列表中包含的小区可以为不需要进行测量的小区，白名单小区列表中包含的小区可以为需要进行测量的小区。
配置至少一个测量上报的触发条件；也就是说，针对测量结果进行测量上报可以包含有触发条件，本示例中，所述触发条件可以为：至少一个距离门限值、持续时长。
相应的，事件X1的触发条件可以为：在一段持续时长(Time to Trigger)内，终端设备与服务小区地面中心的第一距离d_s比终端设备到相邻小区地面中心的第二距离d_n大于第一门限d_th1，并且终端设备到服务小区地面中心的第一距离与终端设备到相邻小区地面中心的第二距离之间差值d_s-d_n的变化大于第二门限d_th2。其中，d_th1和d_th2都大于0。所述满足触发条件的持续时间，第一门限d_th1和第二门限d_th2由网络RRC配置。不同的测量上报配置对应的满足触发条件的持续时间和/或第一/第二门限值不同。
使用测量标识将测量对象和测量上报进行关联。也就是将每个测量对象关联到一个测量上报，不同的测量对象可以与同一个测量上报相关联。
3、终端设备根据所述测量配置，对自己与服务小区地面中心的第一距离以及所述终端设备与各个相邻小区地面中心的第二距离进行测量。
其中，终端设备与每一个相邻小区的地面中心的距离均可以作为前述第二距离，针对每一个第二距离的处理相同，因此不再重复说明。
若在持续时长内保持所述第一距离与第二距离之间的差值大于第一距离门限值，以及第一差值与第二差值之间的变化量大于第二门限值；所述第一差值为在持续时长的起始时刻所述第一距离与第二距离之间的差值，第二差值为在持续时长的终止时刻对应的所述第一距离与第二距离之间的差值；则确定相邻小区满足所述测量配置中所包含的触发条件。
也就是说，如果存在至少一个相邻小区满足测量事件X1的触发条件，即在一段持续时间内终端设备到服务小区地面中心的第一距离比终端设备到该相邻小区地面中心的第二距离大于第一门限，并且第一距离与终端设备到第二距离之间差值的变化量在该持续时间内保持大于第二门限。则终端设备将这些满足触发条件的一个或多个相邻小区的测量结果均向通信设备进行测量上报。
具体的，所述终端设备向所述服务小区的通信设备上报包含有所述相邻小区对应的第二距离的测量结果。
进一步地，所述测量结果中，可以包括有：在持续时长内测量到的第一距离，第二距离。
比如，在测量结果中可以包含有在所述持续时长内，相邻小区的标识，以及相邻小区所对应的第二距离，服务小区的标识以及服务小区对应的第一距离。其中，第二距离可以为所述持续时长起始到结束时刻内所对应的全部第二距离；测量结果中上报的第一距离可以为所述持续时长起始到结束时刻内所对应的全部第一距离。
4、终端设备的服务小区的通信设备根据来自终端设备的测量结果(可称为距离测量结果)，确定终端设备切换的目标小区。
具体来说，如果服务小区的通信设备收到了终端设备针对一个相邻小区的测量报告，则服务小区的通信设备根据所述测量报告可以确定该上报的相邻小区为切换的目标小区。
如果服务小区的通信设备收到了终端设备针对多个相邻小区的测量报告，则由服务小区的通信设备从上报的相邻小区中选择一个小区作为目标小区。
服务小区的通信设备如何从这多个相邻小区中选择一个目标小区取决于服务小区的通信设备实现。比如，服务小区的通信设备可以从多个相邻小区中随机选取一个作为目标小区；或者，可以选取通信质量最好的一个基站作为目标小区；又或者，可以根据基站的物理位置选取最近的一个作为目标小区；再或者可以选择当前处理负荷最小的一个作为目标小区。其他选择方式本实施例中不再穷举。
5、服务小区的通信设备向目标小区的通信设备发送切换请求。
6、目标小区的通信设备向服务小区的通信设备发送切换确认消息，同时包含切换命令。
7、服务小区的通信设备将来自目标小区的通信设备的切换命令转发给终端设备，终端设备收到后执行切换。
一种示意图，如图8所示，终端设备的服务小区为cell1，服务小区的通信设备，可以为图中gNB1；目标小区的通信设备可以为图中的gNB2；具体的：
1、终端设备向gNB1进行定位能力上报；具体为通过RRC消息告知gNB1自己具有定位能力。
2、终端设备接收来自gNB1的测量配置，可以将其称为距离测量配置，指示UE对相邻小区cell2和cell3进行距离测量。同时配置测量上报类型为事件X1触发，事件X1对应的满足触发条件的持续时间为TTT，第一门限和第二门限分别为d_th1和d_th2。
3、终端设备根据网络的测量配置，进行测量并进行测量结果上报。
具体来说，UE测量自己与服务小区地面中心位置的第一距离第一距离d1，同时测量自己与相邻小区cell2地面中心位置的距离第二距离d2，以及自己与相邻小区cell3地面中心位置的另一个第二距离可以表示为d3。测量结果可以如图7所示。
具体的，在T1时刻，终端设备测量的第一距离d1比第二距离d2大于第一门限值d_th1，并且以T1时刻作为起始时刻，终端设备在此之后的持续时间TTT时间内都满足d1比d2大于第一门限d_th1，并且从T1时刻到T2时刻，d1-d2的变化量保持大于第二门限d_th2，即满足测量事件X1的上报条件，则向gNB1进行测量报告。
4、gNB1根据来自终端设备的测量报告，确定终端设备切换的目标小区，并且确定该目标小区的通信设备可以为gNB2。
5、gNB1向gNB2发送切换请求。
6、gNB2向gNB1发送切换确认消息，同时在所述切换确认小区中可以包含切换命令。
7、gNB1将来自gNB2的切换命令转发给终端设备；然后，终端设备收到后执行切换。终端设备断开与gNB1的连接，与gNB2建立连接。
示例2、
与示例1不同之处在于，所述终端设备基于第一距离、第二距离，确定是否满足所述第一条件，包括：
当第一距离以及第二距离为以下情况时，确定相邻小区满足所述测量配置中所包含的触发条件：
在持续时长内保持第一距离大于第三门限；
在持续时长内保持所述第二距离小于第四门限；
在持续时长的起始时刻以及终止时刻对应的第一距离的变化量大于第五门限；
在持续时长的起始时刻以及终止时刻对应的第二距离的变化量小于第六门限。
也就是说，本示例与示例1不同在于，触发条件设置的不同，其中不再针对第一距离以及第二距离之间的差值的变化量进行判断，而是针对第一距离在持续时长内的变化量以及第二距离在持续时长内的变化量来进行判断。
对于具有定位能力的终端设备，终端设备基于自己到小区地面中心位置之间距离的测量，当终端设备与服务小区地面中心位置的第一距离大于第三RTT门限且终端设备与相邻小区地面中心位置的距离小于第四门限，并且终端设备与服务小区地面中心位置的第一距离的变化大于第五门限且终端设备与相邻小区地面中心位置的距离的变化小于第六门限时，终端设备进行测量上报，触发服务小区的通信设备准备切换。
具体的，
步骤1与前述示例1相同，不再赘述。
只是在步骤2中获取到的RRC配置的测量信息的内容不同，配置RTT测量的相关参数。具体地：
配置至少一个测量对象，所述至少一个测量对象中的每个测量对象为一个频率内的NTN载波频率或一个频率间的NTN载波频率。对于每个配置了测量的NTN载波频率，网络可以配置与该载波频率相关的小区偏移量列表，黑名单小区列表和白名单小区列表。
配置至少一个测量上报，所述至少一个测量上报中的每个测量上报的测量上报类型为事件触发。所述事件X2触发的条件为：在一段持续时间(Time to Trigger)内，终端设备与服务小区地面中心位置的第一距离d_s大于第三门限d_th3且终端设备与相邻小区地面中心位置的距离d_n小于第四门限d_th4，并且终端设备与服务小区地面中心位置的第一距离的变化量大于第五门限d_th5且终端设备与相邻小区地面中心位置的距离的变化小于第六门限d_th6。其中，d_th3,d_th4和d_th5大于0，d_th6小于0。所述满足触发条件的持续时间，第三门限d_th3，第四门限d_th4，第五门限d_th5和第六门限d_th6由网络RRC配置。不同的测量上报配置对应的满足触发条件的持续时间和/或第三/四/五/六门限值不同。
使用测量标识将测量对象和测量上报进行关联。每个测量对象关联到一个测量上报，不同的测量对象可以与同一个测量上报相关联。
相应的，步骤3也存在不同，具体的：终端设备根据网络的测量配置，对自己与服务小区地面中心的距离以及自己与各个相邻小区地面中心的距离进行测量。如果存在至少一个相邻小区满足测量事件X2触发条件，即在一段持续时间内终端设备与服务小区地面中心位置的第一距离大于第三RTT门限且终端设备与该相邻小区地面中心位置的距离小于第四门限，并且终端设备与服务小区地面中心位置的第一距离的变化量大于第五门限且终端设备与该相邻小区地面中心位置的距离的变化量小于第六门限。则终端设备向服务小区基站进行测量上报。
后续的步骤同示例1的步骤4-7，不再赘述。
该示例的一种示意，终端设备的服务小区为cell1，服务小区的通信设备为图10中的gNB1；目标小区的通信设备可以为图10中的gNB2；具体的：
1、终端设备通过RRC消息告知gNB1自己具有定位能力。
2、终端设备接收来自gNB1的测量配置，指示终端设备对相邻小区cell2和cell3进行距离测量。同时配置测量上报类型为事件X2触发，事件X2对应的满足触发条件的持续时间为TTT，第三门限，第四门限，第五门限和第六门限分别为d_th3，d_th4， d_th5和d_th6。
3、终端设备根据网络的测量配置，测量自己与服务小区地面中心的第一距离d1，同时测量自己与相邻小区cell2地面中心的第二距离d2，以及自己与相邻小区cell3地面中心的另一个第二距离，可以表示为d3。然后上报测量结果。
测量结果可以如图9所示。
在T1时刻，终端设备测量的d1大于门限d_th3且终端设备测量的d2小于门限d_th4，并且以T1时刻作为起始时刻，终端设备在此之后的持续时间TTT时间内都满足d1大于门限d_th3且d2小于门限d_th4，并且从T1时刻到T2时刻，d1的变化量大于门限d_th5且d2的变化量小于门限d_th6，即满足测量事件X2的上报条件，则向gNB1进行测量报告。
4、gNB1根据来自终端设备的距离测量报告，确定终端设备切换的目标基站为gNB2。
5、gNB1向gNB2发送切换请求。
6、gNB2向gNB1发送切换确认消息，同时包含切换命令。
7、gNB1将来自gNB2的切换命令转发给终端设备，终端设备收到后执行切换。终端设备断开与gNB1的连接，与gNB2建立连接。
可见，通过采用上述方案，就能够基于终端设备当前所处的位置与服务小区的第一距离以及与相邻小区的第二距离，来确定是否满足切换的条件，进而确定是否触发进行服务小区至目标小区的切换处理。如此，就能够有效地保证用户在NTN系统中移动过程中进行有效的切换，避免由于NTN通信中如果仍然采用RSRP进行切换判断时出现由于RSRP的变化不明显，所带来的切换失败的问题，从而保证了终端设备在NTN系统中的服务质量，并且使用户获得良好的体验。
本发明实施例提供的另一种切换处理方法，如图11所示，所述方法还包括：
步骤41：终端设备获取通信设备配置的第一条件；其中，所述第一条件为基于第一距离以及第二距离确定触发执行由服务小区切换至目标小区的处理的条件；其中，所述第一距离为所述终端设备所在位置与所在服务小区的中心位置之间的距离；所述第二距离为所述终端设备所在位置与相邻小区的中心位置之间的距离；
步骤42：所述终端设备基于第一距离、第二距离，确定是否满足所述第一条件；
步骤43：若满足所述第一条件，则所述终端设备执行由服务小区至目标小区的切换处理；其中，所述目标小区为终端设备的相邻小区中之一。
另一种切换处理方法，如图12所示，所述方法还包括：
步骤51：通信设备向终端设备配置第一条件；其中，所述第一条件为基于第一距离以及第二距离确定触发进行切换处理的条件；其中，所述第一距离为所述终端设备所在位置与所在服务小区的中心位置之间的距离；所述第二距离为所述终端设备所在位置与相邻小区的中心位置之间的距离；所述通信设备为所述终端设备所在的服务小区对应的通信设备。
本实施例中，终端设备、通信设备的说明与前述实施例相同，不再赘述。本实施例与前述实施例不同在于，针对了第二类切换处理类型，第二类切换处理可以为终端设备确定目标小区，然后终端设备直接向目标小区的通信设备发起切换的处理。
下面结合两个示例对本实施例的方案进行详细说明：
示例3、
前述示例1、2均针对第一类切换，示例3为针对第二类切换，所述第二类切换为终端设备确定目标小区的切换处理。
其中，所述第一条件，为：
RRC消息中携带的条件切换命令中携带的条件；
其中，所述条件切换命令为第二类切换中传输的信息；所述第二类切换为终端设备确定目标小区的切换处理。
所述条件切换命令中携带的条件，包括：
至少一个相邻小区中每一个相邻小区对应的触发进行切换处理的条件。
所述每一个相邻小区对应的触发进行切换处理的条件，包括：
至少一种距离门限值、持续时长。
本示例是对于具有定位能力的终端设备，基站给终端设备发送条件切换命令，终端设备基于自己到小区地面中心位置之间距离的测量，当终端设备到服务小区地面中心位置的第一距离比终端设备到相邻小区地面中心位置的距离大于第七门限，并且终端设备到服务小区地面中心位置的第一距离与终端设备到相邻小区地面中心位置的距离之间差值的变化大于第八门限时，终端设备执行条件切换。
具体实施过程如下：
1、终端设备通过RRC消息告知网络自己是否支持定位功能，该指示信息可以携带在终端设备能力消息中。
2、终端设备接收来自服务小区的通信设备的条件切换命令；
所述第一条件，为：RRC消息中携带的条件切换命令中携带的条件；
其中，所述条件切换命令为第二类切换中传输的信息；所述第二类切换为终端设备确定目标小区的切换处理。
其中，所述条件切换命令中携带的条件包括：
至少一个相邻小区中每一个相邻小区对应的触发进行切换处理的条件。
所述每一个相邻小区对应的触发进行切换处理的条件，包括：至少一种距离门限值、持续时长。
具体来说，所述条件切换命令包含以下信息：
终端设备切换的候选目标小区列表。
对于每个候选的切换目标小区，终端设备切换到该小区所需要满足的条件，即：在一段持续时间内，终端设备与服务小区地面中心位置的第一距离比终端设备与候选目标小区地面中心位置的第二距离大于第七RTT门限d_th7，并且终端设备与服务小区地面中心位置的第一距离比终端设备与候选目标小区地面中心位置的第二距离之间差值的变化大于第八门限d_th8。其中，d_th7和d_th8都大于0。所述满足触发条件的持续时间，第七门限d_th7和第八门限d_th8同样由基站通知。不同的候选目标小区对应的满足触发条件的持续时间和/或第七/八门限值可以相同也可以不同。
3、终端设备对自己与服务小区地面中心位置的第一距离以及自己与各个候选目标小区地面中心位置的第二距离进行测量。
也就是说，所述终端设备基于第一距离、第二距离，确定是否满足所述第一条件，包括：
若在持续时长内保持所述第一距离与第二距离之间的差值大于第七距离门限值，以及第一差值与第二差值之间的变化量大于第八门限值；所述第一差值为在持续时长的起始时刻所述第一距离与第二距离之间的差值，第二差值为在持续时长的终止时刻对应的所述第一距离与第二距离之间的差值；
则确定满足所述相邻小区对应的触发进行切换处理的条件。
具体的，判断是否存在至少一个候选目标小区满足条件切换的切换条件，即在一段持续时间内终端设备与服务小区地面中心位置的第一距离比终端设备与该候选目标小区地面中心位置的距离大于第七RTT门限，并且终端设备与服务小区地面中心位置的第一距离比终端设备与该候选目标小区地面中心位置的距离之间差值的变化大于第八 门限：
如果满足切换条件的候选目标小区的个数为1，则终端设备确定所述满足切换条件的候选目标小区为执行切换的目标小区。
如果满足切换条件的候选目标小区的个数大于1，则终端设备从所述满足切换条件的多个候选目标小区中选择一个作为执行切换的目标小区。
4、终端设备根据确定的目标小区，执行切换处理。
一种具体实施流程参见图13，说明如下：
终端设备的服务小区为cell1，服务小区的通信设备为gNB1。终端设备通过RRC消息告知gNB1自己具有定位能力；目标小区可以为候选目标小区中的一个，其中一个候选目标小区cell2的通信设备可以为图中的gNB2，另一个候选目标小区cell3的通信设备可以为图中的gNB3；具体的：
1、终端设备进行定位能力上报；具体为终端设备向服务小区也就是源小区的通信设备gNB1进行定位能力上报；此时，eNB1可以通知gNB2、gNB3这两个候选目标小区进行CHO(条件切换)准备。
2、终端设备接收来自gNB1的条件切换命令，指示终端设备切换的候选目标小区为cell2和cell3，同时指示终端设备执行切换所需要满足的条件为：在一段持续时间TTT内，终端设备与服务小区地面中心位置的第一距离比终端设备与候选目标小区地面中心位置的第二距离大于第七门限d_th7，并且终端设备与服务小区地面中心位置的第一距离与终端设备与候选目标小区地面中心位置的第二距离之间差值的变化量大于第八门限d_th8。
3、终端设备进行距离测量；
具体可以为：测量自己与服务小区地面中心位置的第一距离d1，同时测量自己与cell2地面中心位置的第二距离d2，以及自己与cell3地面中心位置的第二距离d3。测量结果如下图14所示。在T1时刻，终端设备测量的d1比d2大于第七门限d_th7，并且以T1时刻作为起始时刻，终端设备在此之后的持续时间TTT时间内都满足d1比d2大于第七门限d_th7，并且从T1时刻到T2时刻，d1-d2的变化量大于第八门限d_th8，终端设备确定gNB2为切换的目标基站。
4、终端设备可以根据距离测量的结果，确定cell2为目标小区，然后确定离开cell1(服务小区也就是源小区)，接入目标小区也就是cell2，终端设备断开与gNB1的连接，与gNB2建立RRC连接。
示例4、
本示例中，对于具有定位能力的UE，基站给UE发送条件切换命令，UE基于自己到小区地面中心位置之间距离的测量，当UE与服务小区地面中心位置的第一距离大于第九门限且UE与邻小区地面中心位置的距离小于第十门限，并且UE与服务小区地面中心位置的第一距离的变化大于第十一门限且UE与邻小区地面中心位置的距离的变化小于第十二门限时，UE执行条件切换。
本示例与示例3不同在于，接收到的条件切换命令有所不同，相应的，所述终端设备基于第一距离、第二距离，确定是否满足所述第一条件，包括：
当第一距离以及第二距离为以下情况时，确定满足所述相邻小区对应的触发进行切换处理的条件：
在持续时长内保持第一距离大于第九门限；
在持续时长内保持所述第二距离小于第十门限；
在持续时长的起始时刻以及终止时刻对应的第一距离的变化量大于第十一门限；
在持续时长的起始时刻以及终止时刻对应的第二距离的变化量小于第十二门限。
具体的所述条件切换命令包含以下信息：
终端设备切换的候选目标小区列表。
对于每个候选目标小区，终端设备切换到该小区所需要满足的条件，即：在一段持续时间内，终端设备与服务小区地面中心位置的第一距离大于第九门限d_th9且终端设备与候选目标小区地面中心位置的第二距离小于第十门限RTT_th10，并且终端设备与服务小区地面中心位置的第一距离的变化大于第十一门限d_th11且终端设备与候选目标小区地面中心位置的第二距离的变化小于第十门限RTT_th12。其中，d_th9，d_th10和d_th11都大于0，d_th12小于0。所述满足触发条件的持续时间，第九门限d_th9,第十门限d_th10,第十一门限d_th11和第十二门限d_th12同样由基站通知。不同的候选目标小区对应的满足触发条件的持续时间和/或第九/十/十一/十二门限值可以相同也可以不同。
相应的，终端设备对自己与服务小区地面中心位置的第一距离以及自己与各个候选目标小区地面中心位置的距离进行测量。如果存在至少一个候选目标小区满足条件切换的切换条件，即在一段持续时间内终端设备与服务小区地面中心位置的第一距离大于第九门限d_th9且终端设备与该候选目标小区地面中心位置的距离小于第十门限RTT_th10，并且终端设备与服务小区地面中心位置的第一距离的变化大于第十一门限d_th11且终端设备与该候选目标小区地面中心位置的距离的变化小于第十门限RTT_th12：
如果满足切换条件的候选目标小区的个数为1，则终端设备确定所述满足切换条件的候选目标小区为执行切换的目标小区。
如果满足切换条件的候选目标小区的个数大于1，则终端设备从所述满足切换条件的多个候选目标小区中选择一个作为执行切换的目标小区。
然后，所述终端设备触发执行切换处理，包括：
从满足对应的触发进行切换处理的条件的相邻小区中确定目标小区，所述终端设备向所述目标小区发起切换处理。
一种具体的处理流程参见图15，包括：
本处理流程中步骤与前述示例3的图13的步骤类似，不同在于，条件切换命令有所不同；以及终端测量结果有所不同。
具体的，在步骤2中，终端设备接收来自gNB1的条件切换命令，指示终端设备切换的候选目标小区为cell2和cell3，同时指示终端设备执行切换所需要满足的条件为：一段持续时间内终端设备与服务小区地面中心位置的第一距离大于第九门限d_th9且终端设备与候选目标小区地面中心位置的第二距离小于第十门限RTT_th10，并且终端设备与服务小区地面中心位置的第一距离的变化大于第十一门限d_th11且终端设备与候选目标小区地面中心位置的第二距离的变化小于第十门限RTT_th12。
3、终端设备测量自己与服务小区地面中心位置的第一距离d1，同时测量自己与cell2地面中心位置的第二距离d2，以及自己与cell3地面中心位置的第二距离d3。
测量结果如图16所示：在T1时刻，终端设备测量的d1大于门限d_th9且终端设备测量的d2小于门限d_th10，并且以T1时刻作为起始时刻，终端设备在此之后的持续时间TTT时间内都满足d1大于门限d_th9且d2小于门限d_th10，并且从T1时刻到T2时刻，d1的变化量大于门限d_th11且d2的变化量小于门限d_th12，则终端设备确定gNB2为切换的目标基站。
本示例中步骤1、4的处理与前述示例3相同，因此不再进行赘述。
可见，通过采用上述方案，就能够基于终端设备当前所处的位置与服务小区的第一距离以及与相邻小区的第二距离，来确定是否满足切换的条件，进而确定是否触发进行服务小区至目标小区的切换处理。如此，就能够有效地保证用户在NTN系统中移动过 程中进行有效的切换，避免由于NTN通信中如果仍然采用RSRP进行切换判断时出现由于RSRP的变化不明显，所带来的切换失败的问题，从而保证了终端设备在NTN系统中的服务质量，并且使用户获得良好的体验。
