Description

通信方法和通信装置
本申请要求于2022年8月9日提交中国专利局、申请号为202210951039.6、申请名称为“通信方法和通信装置”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
本申请实施例涉及通信领域，更具体地，涉及一种通信方法和通信装置。
背景技术
在卫星通信与第五代(the 5th generation，5G)移动通信***(the 5G mobile communications system，5GS)融合的场景(例如，卫星上部署RAN的射频模块)中，由于中轨道(middle earth orbit，MEO)和低轨道(low earth orbit，LEO)等非地球同步卫星相对地面运动，第三代合作伙伴计划(3rd generation partnership project，3GPP)规定随着卫星的移动，卫星需要广播当前波束覆盖地面区域对应的追踪区域代码(tracking area code，TAC)。
随着卫星的移动，可能存在一个时段卫星的波束同时覆盖多个追踪区域(tracking area，TA)的情况。为了避免因为卫星的移动，切换广播的TAC，而导致静止在TA1的终端因收到TAC2而发起移动注册更新，3GPP规定卫星在移动过程中如果覆盖了不同TA区域，则要同时广播所覆盖的多个TA对应的TAC。
在卫星波束同时覆盖多个TA时，现有的针对终端的移动性限制方案中，存在终端可能绕过移动性限制的问题。

5G通信***中，针对UE的移动性限制主要指的是限制UE的移动性处理或业务访问。在本申请的实施例中，主要涉及与追踪区域(tracking area，TA)有关的UE的移动性限制。与TA有关的包括禁止区域(forbidden Area)和服务受限区域(service area restrictions)。在禁止区域，UE不允许与网络发起任何通信。服务受限区域可以分为“允许区域”和“不允许区域”，如果UE在“不允许区域”，则UE和网络不允许发起“服务请求”或任何用户面数据、控制面数据、异常数据上报、会话管理(session management，SM)信令的连接请求，获取与移动性无关的用户业务。
2、卫星通信
卫星通信技术指的是地面上的无线通信设备通过卫星接入网络的技术。卫星通信相对于传统的移动通信***，拥有更广的覆盖范围，可以帮助5G网络覆盖人员稀少的偏远地区、海洋和孤岛等地面网络难以到达的区域。
基于图1所示的通信***架构，可以将卫星通信与5G移动通信***(the 5th-generation mobile communications system，5GS)进行融合。目前，卫星通信与5GS融合的一种场景为：卫星作为3GPP接入，UE通过卫星接入5GS。
图2是一种卫星通信与5GS融合的场景示意图。从图2中可以看出，卫星可以包含RAN全部或 部分接入网络的功能，因此，UE可以通过卫星接入5G核心网(5G Core Network，5GC)。其中，5GC可以包括如图1中所示的AMF、AF、UDM等核心网网元。
示例性地，图2中的卫星可以是低轨道卫星(low earth orbit，LEO)、中轨道卫星(mid earth orbit，MEO)和其他卫星(Other SAT)等。
由于MEO和LEO等非地球同步卫星相对地面运动，3GPP规定随着卫星的移动，卫星需要广播当前波束覆盖地面区域对应的追踪区域代码(tracking area code，TAC)。在卫星的移动过程中，可能存在一个时段卫星的波束同时覆盖多个TA的情况。为了避免因为卫星的移动，切换广播的TAC，而导致静止在一个TA的UE因收到另一个TA对应的TAC而发起移动注册更新(mobility registration update，MRU)，3GPP规定卫星在移动过程中如果覆盖了不同TA区域，则要同时广播所覆盖的多个TA区域对应的TAC。
如图3中所示，卫星在一个时段同时覆盖TA1和TA2，为了避免因为卫星的移动，切换广播的TAC，而导致静止在TA1的UE因收到TAC2而发起移动注册更新，卫星需要同时广播TA1、TA2对应的TAC1和TAC2。这样，当UE位于某个TA1边界附近时，由于总是能收到自身所在TA1的TAC1，而不发起MRU流程，避免了UE被动切换和卫星移动切换TA时大量UE发起注册更新造成的信令冲击。
然而，卫星广播多个TAC也带来了新的问题，RAN可能无法准确判断当前UE所在的位置，因而可能将当前广播的多个TAC通过UE位置信息(UE location information，ULI)上报至AMF。针对RAN上报的多个TAC，网络对UE的移动性限制采用宽松的原则。即如果上报的多个TAC对应的TA全部为服务受限或禁止的TA，则对UE采取移动性限制，否则，不对UE采取移动性限制。此时，当上报的多个TAC中部分TAC对应的TA受到移动性限制(比如某个TAC对应的TA是禁止区域或服务受限区域)，若不对UE进行移动性限制，则会造成UE可能绕过移动性限制的问题。
现有的一种方案中，为了让RAN能上报UE的准确位置、或者说确定UE所在的TA，RAN需要依赖UE的全球导航卫星***(global navigation satellite system，GNSS)定位能力。具体地，RAN接收UE上报的自身的位置信息，其中，该位置信息是基于UE的GNSS定位能力确定的，RAN可将UE上报的位置信息映射成对应的TAC，并告知AMF。从而AMF可以获知UE所在的实际位置，即UE所在的TA。AMF可以确定UE所在的TA是否为禁止区域或服务受限区域，继而确定是否对UE实施移动性限制。
但是，在该方案中，RAN需要依赖UE上报的自身的位置信息来确定UE所在的TA，而UE上报的自身的位置信息是基于自身的GNSS定位能力确定的，UE上报的自身的位置信息存在可靠性问题。例如，该UE可能是恶意的，其可能通过伪造位置信息而使自身绕过移动性限制。
有鉴于此，本申请提供一种通信方法和通信装置，在RAN无法准确判断当前终端设备所在的位置上报多个TAC的情况下，网络侧能够有效地对终端设备实施移动性限制，防止终端设备绕过移动性限制。
为了便于理解本申请实施例，做出以下几点说明。
第一，在本申请中示出的第一、第二以及各种数字编号(例如，“#1”、“#2”等)仅为描述方便，用于区分的对象，并不用来限制本申请实施例的范围。例如，区分不同的信息等。而不是用于描述特定的顺序或先后次序。应该理解这样描述的对象在适当情况下可以互换，以便能够描述本申请的实施例以外的方案。
第二，本申请中涉及的术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
下文将结合附图详细说明本申请实施例提供的通信方法。本申请提供的实施例可以应用于上述图1和图2中任一个所示的网络架构中，不作限定。
图4示出了本申请实施例提供的一种通信方法400的示意图。方法400可以包括如下步骤。
S410，接入网设备向接入与移动管理网元发送第一信息。
相应地，该接入与移动管理网元接收来自该接入网设备的第一信息。
该第一信息包括该接入网设备覆盖的多个区域的标识。
一个示例中，该多个区域是以TA为粒度划分的，或者说，该接入网设备覆盖的多个区域为多个TA。
另一个示例中，该接入网设备覆盖的区域是以小于TA的范围为粒度划分的，或者说，该接入网设备覆盖的多个区域为多个小于TA范围的区域。
需要说明的是，该多个区域可以是该接入网设备覆盖的全部区域，或者，该接入网设备覆盖的全部区域中的部分区域。
一种可能的实现方式中，该接入网设备可以在终端设备的注册流程中向该接入与移动管理网元发送该第一信息。

可选地，S420，该接入与移动管理网元获取该终端设备的签约数据。
具体地，该接入与移动管理网元可以通过统一数据管理网元或第一接入与移动管理网元获取该终端设备的签约数据。
其中，该第一接入与移动管理网元可以为执行本申请实施例方法之前服务该终端设备的接入与移动管理网元。

其中，UE-Based定位模式可以理解为：终端设备自己获取定位测量数据，并根据获取的定位测量数据计算终端设备的位置。可选地，在一些实施例中，终端设备可以从网络侧获取协助数据(assistance data)，该辅助数据可以辅助确定终端设备的位置估计。
UE-Assisted定位模式可以理解为：终端设备获取定位测量数据，并将定位测量数据发给其他网元(例如，位置管理网元)，以便其他网元确定终端设备的位置估计。
基于网络的定位模式可以理解为：由网络侧(如位置管理网元)获取终端设备的测量信息，并进行 终端设备的位置估计。
本申请实施例中终端设备的位置估计，可以为终端设备的经纬度坐标、笛卡尔或地心地固坐标系(earth-centered earth-fixed，ECEF)的XYZ坐标或其它可以表征位置的信息或数据等，不作限定。
在该第一指示信息指示该接入与移动管理网元要求的一种或多种定位模式的情况下，该位置管理网元按照该接入与管理网元要求的定位模式进行定位。如果该位置管理网元确定该终端设备不支持该第一指示信息指示的定位模式，后续的流程可以不执行，即该接入与移动管理网元按现有宽松原则对该终端设备实施移动性限制。
再一个示例中，该第一指示信息可以指示该接入与移动管理网元偏好的至少一种定位模式。该至少一种定位模式可以参考第一个示例中的描述。
在该第一指示信息指示该接入与移动管理网元偏好的一种或多种定位模式的情况下，该位置管理网元可以结合终端设备的定位能力判断是否按照该第一指示信息指示的定位模式进行定位。
又一个示例中，该第一指示信息还可以指示该接入与移动管理网元禁止的至少一种定位模式。该至少一种定位模式可以参考第一个示例中的描述。
在该第一指示信息指示该接入与移动管理网元禁止的定位模式的情况下，该位置管理网元可以选择终端设备支持的且不是该接入与移动管理网元禁止的定位模式进行定位。
又一个示例中，该第一指示信息可以指示定位请求的目的。示例性地，该定位请求的目的可以是：为了确定终端设备所在的区域、或为了实施移动性限制、或为了验证卫星接入下终端设备的位置而请求的定位。
在该第一指示信息指示定位请求的目的情况下，该位置管理网元可以根据该第一指示信息选择上述定位模式中的至少一种。
通过该接入与移动管理网元向位置管理网元发送指示定位方法的指示信息，可以提升确定终端设备的位置信息的可靠性。
该位置管理网元向该接入与移动管理网元发送该终端设备的位置信息具体包括：该位置管理网元向该接入与移动管理网元发送该终端设备的位置估计；或者，该位置管理网元向该接入与移动管理网元发送该终端设备所在的区域的标识。
若该位置管理网元向该接入与移动管理网元发送该终端设备所在的区域的标识，则该方法还包括：该位置管理网元根据该终端设备的位置估计确定该终端设备设备所在的区域。具体地，该位置管理网元可以将该终端设备的位置估计映射为该终端设备所在的区域的标识。例如，映射为该终端设备所在的TA对应的TAC，或者，映射为该终端设备所在的区域的标识，该区域的范围小于TA的范围。
S440，该接入与移动管理网元基于所述终端设备的位置信息确定是否对所述终端设备实施移动性限制。
具体地，若该接入与移动管理网元接收到来自该位置管理网元的该终端设备所在的区域的标识，则该接入与移动管理网元根据该终端设备所在的区域的标识，以及该终端设备的签约数据中的移动性限制区域确定是否对所述终端设备实施移动性限制。
若该接入与移动管理网元接收到来自该位置管理网元的该终端设备的位置估计，该方法还可以包括：该接入与移动管理网元根据该终端设备的位置估计确定该终端设备所在的区域；该接入与移动管理网元根据该终端设备所在的区域的标识，以及该终端设备的签约数据中的移动性限制区域确定是否对所述终端设备实施移动性限制。
其中，该接入与移动管理网元根据该终端设备的位置估计确定该终端设备所在的区域具体可以是：该接入与移动管理网元将该终端设备的位置估计映射为该终端设备所在的区域的标识。
示例性地，该接入与移动管理网元根据该终端设备所在的区域的标识，以及该终端设备的签约数据中的移动性限制区域确定是否对所述终端设备实施移动性限制包括：若该接入与移动管理网元确定该终端设备所在的区域属于该终端设备的签约数据中的移动性限制区域，则该接入与移动管理网元对该终端设备实施移动性限制。
接入与移动管理网元执行终端设备的移动性限制的详细步骤可以参考现有的相关描述。
基于上述方案，接入与移动管理网元可以在确定该接入网设备覆盖的该多个区域中的部分区域属于终端设备的签约数据中的移动性限制区域的情况下，通过调用定位服务获取该终端设备的位置信息， 并根据该终端设备的位置信息确定是否对该终端设备实施移动性限制，从而可以防止终端设备绕过移动性限制。
图5示出了本申请实施例提供的一种通信方法500的示意图。该方法中以注册流程为例来说明本申请实施例提供的通信方法。如图5所示，该方法可以包括以下步骤。
S501，UE向RAN发送注册请求(registration request)；相应地，RAN接收来自UE的注册请求。
其中，RAN的全部或部分功能(如射频模块)可以由卫星实现。RAN在一个时间段内可能覆盖多个TA。
该注册请求可以携带UE的标识、注册类型等。具体可参考现有的相关描述。
S502，RAN选择AMF。
示例性地，RAN在接收到来自UE的注册请求后，选择AMF。该AMF用于UE的接入和移动性管理。RAN选择AMF的具体过程可参考现有的相关描述。
S503，RAN向选择的AMF发送注册请求以及UE的位置信息(UE location information，ULI)。
相应地，AMF接收来自AMF的该注册请求以及ULI。
其中，该注册请求可以参考现有的相关描述；该ULI中包括RAN覆盖的多个TA对应的TAC(为了简便，记为第一TAC)。该多个TA可以是RAN覆盖的全部TA，或者是该RAN覆盖的全部TA中的部分。
S504，AMF获取UE的签约数据。
AMF可以从UDM获取UE的签约数据。该签约数据中包括UE的移动性限制区域的信息。该UE的移动性限制区域可以包括至少一个TA，UE的移动性限制区域的信息包括该至少一个TA对应的TAC(为了简便，记为第二TAC)。
例如，该至少一个TA包括禁止区域和/或“不允许区域”对应的TA。即UE在该至少一个TA中的访问、或移动受限。
S505，判断第一TAC与第二TAC是否存在交集，且第一TAC不是第二TAC的子集。
若不是，则按照现有的方案执行UE的移动性限制。
若是，则执行后续步骤。
举例来说，第一TAC包括{TAC#1，TAC#2，TAC#3}，第二TAC包括{TAC#2，TAC#3}，第一TAC与第二TAC存在交集{TAC#2，TAC#3}，且第一TAC不是第二TAC的子集；第一TAC包括{TAC#1，TAC#2，TAC#3}，第二TAC包括{TAC#2，TAC#4}，则第一TAC与第二TAC存在交集{TAC#2}，且第一TAC不是第二TAC的子集。
在执行后续步骤前，AMF可通过RAN向UE发送注册接受消息。
S506，AMF向LMF发送定位请求。
相应地，LMF接收来自AMF的该定位请求。
例如，该定位请求可以是Nlmf_Location_DetermineLocation Request。
该定位请求可以携带UE的定位能力，UE的定位能力指示UE支持的定位方法(也可以称为定位模式)。
该定位请求还可以携带指示信息#1，该指示信息#1指示定位模式。
一个示例中，该指示信息#1可以包括AMF要求的一种或多种定位模式。
在该指示信息#1包括AMF要求的一种或多种定位模式的情况下，LMF按照该指示信息#1指示的定位模式进行定位。
例如，AMF要求的定位模式可以是UE-Based定位模式、UE-Assisted定位模式以及基于网络的定位模式中的至少一种。
再一个示例中，该指示信息#1可以包括AMF偏好的一种或多种定位模式。
该多种定位模式可以参考第一个示例中的描述。
在该指示信息#1包括AMF偏好的一种或多种定位模式的情况下，该LMF可以结合UE的定位能力判断是否按照该指示信息#1指示的定位模式进行定位。
例如，AMF指定偏好基于网络的定位模式。如果LMF确定UE支持基于网络的定位模式，则LMF选择基于网络的定位模式定位。如果LMF确定UE不支持基于网络的定位模式，则LMF可能选择UE 支持的其他定位模式，例如，选择UE-Assisted定位模式。
再如，AMF可以指示其偏好的定位模式的优先级，相应地，LMF根据该优先级信息确定定位模式。示例性地，AMF指示的优先级由高到低的定位模式的可以是：基于网络的定位模式、UE-Assisted定位模式、UE-Based定位模式。LMF基于该指示信息#1优先选择优先级高的定位模式，在UE不支持高优先级的定位模式的情况下，LMF可以选择较低优先级的定位模式。若AMF偏好的定位模式UE都不支持，则LMF选择其他UE支持的定位模式。
再一个示例中，该指示信息#1可以指示AMF禁止的定位模式。
该多种定位模式可以参考第一个示例中的描述。
在该指示信息#1指示AMF禁止的定位模式的情况下，该LMF可以选择UE支持的且不是AMF禁止的定位模式进行定位。
再一个示例中，该指示信息#1可以指示定位请求的目的。
在该指示信息#1指示定位请求的目的情况下，该LMF可以选择UE-Based定位模式、UE-Assisted定位模式以及基于网络的定位模式中的至少一种。
例如，定位请求的目的可以是：为了确定UE所在的TA、或为了实施移动性限制、或为了验证卫星接入下UE位置而请求的定位。
可以理解，在以上示例中，若LMF确定UE的定位能力不支持AMF要求的定位模式或AMF禁止的定位模式之外的定位模式，则LMF可能采用其他UE支持的定位方法；或者，LMF还可以拒绝定位请求并向AMF返回拒绝的原因，此情况下，后续流程不需要执行，AMF按现有宽松原则实施移动性限制。
S507，LMF执行定位流程。
根据选择的定位模式的不同，LMF执行定位流程包括两种情况。
情况一：
若在S506中LMF根据指示信息#1确定采用基于网络的定位模式，则该定位流程可以包括S508至S510：
S508，LMF通过AMF向RAN发送下行新无线定位协议A(new radio position protocol a，NRPPa)消息。
示例性地，LMF可以通过N1N2消息传输容器消息(Namf_Communication_N1N2MessageTransfer)或N2消息传输容器消息(Namf_Communication_NonUeN2MessageTransfer)向AMF发送NRPPa消息；然后由AMF通过N2传输(N2Transport)将NRPPa消息发送至RAN。
S509，RAN获取测量信息。
S510，RAN通过AMF向LMF发送该测量信息。
示例性地，RAN通过N2Transport将测量信息发送至AMF；再由AMF通过N1N2通知消息(Namf_Communication_N1N2MessageNotify)或N2通知消息(Namf_Communication_NonUeN2MessageNotify)将测量信息发送至LMF。
情况二：
若在S506中LMF根据指示信息#1确定采用UE-Assisted定位模式或UE-Based定位模式，则该定位流程可以包括S511至S513：
S511，LMF通过AMF向UE发送下行长期演进***定位协议(long term evolution position protocol，LPP)消息。
示例性地，LMF可以通过N1N2消息传输容器消息(Namf_Communication_N1N2MessageTransfer)向AMF发送下行LPP消息，然后，由AMF通过下行NAS消息传输(DL NAS TRANSPORT)将下行LPP消息发送至UE。
S512，UE获取测量信息和/或确定位置估计。
S513，UE通过AMF向LMF发送测量信息或者位置估计。
示例性地，UE通过上行NAS消息传输(UL NAS TRANSPORT)将上行LPP消息发送至AMF；再由AMF通过N1通知消息(Namf_Communication_N1MessageNotify)将上行LPP消息发送至LMF。
需要说明的是，若LMF采用UE-Assisted定位模式或UE-Based定位模式，且需要网络提供辅助信 息，则也需要执行S508至S510获取网络辅助的测量信息。
可选地，S514，LMF确定UE的位置估计。
LMF可以基于S510和/或S513中的测量信息确定UE的位置估计。
可以理解，若S513中UE通过AMF向LMF发送UE的位置估计，则该步骤可以不予执行。
本申请实施例中UE的位置估计，可以为终端设备的经纬度坐标、笛卡尔或地心地固坐标系(earth-centered earth-fixed，ECEF)的XYZ坐标或其它可以表征位置的信息或数据等，不作限定。
S515，LMF确定UE的位置信息并向AMF发送定位响应。
例如，该定位响应可以是Nlmf_Locaion_Determine Location Response。
该定位响应携带该UE的位置信息。根据UE的位置信息的不同，S516具体可以分为两种情况。
情况一：
S515a，LMF将UE的位置估计映射为UE所在的TA对应的TAC。
S515b，LMF向AMF发送定位响应，该定位响应携带该UE所在的TA对应的TAC。
相应地，AMF接收来自LMF的定位响应。
情况二：
S515c，LMF向AMF发送定位响应，该定位响应携带UE的位置估计。
以上两种情况中，可选地，该定位响应还可以携带LMF所采用的定位模式。AMF可参考LMF返回的采用的定位模式确定该位置估计的可靠程度。
对应情况二，该方法还可以包括S516，AMF将LMF返回的UE位置估计映射为UE所在的TA对应的TAC。
S517，AMF根据UE所在的TA对应的TAC，以及UE的移动性限制区域对应的TAC确定是否对该UE实施移动性限制。
示例性地，AMF可以查询该UE所在的TA对应的TAC是否为第二TAC中的TAC，如果是，则AMF执行UE的移动性限制。例如，如果该UE所在的TA属于移动性签约数据中的禁止区域，则AMF发起解注册流程或拒绝UE的注册请求。
基于上述方案，在第一TAC中部分TAC属于第二TAC的情况下，AMF可以通过调用定位服务，确定UE当前所在TA的TAC，并根据UE当前所在区域的TAC以及移动性限制签约数据来判断是否执行UE的移动性限制，从而可以防止该UE绕过移动性限制。
根据方法500实施的UE的移动性限制可以看作基于TA的粒度实施的移动性限制。
图6示出了本申请实施例提供的另一种通信方法600的示意图。不同于方法500中的TA，方法600可以以小于TA范围的区域的粒度实施UE的移动性限制。该方法600可以包括如下步骤。
S601，UE向RAN发送注册请求。
相应地，RAN接收来自UE的注册请求。
S602，RAN选择AMF。
步骤S601、S602可以分别参考S501、S502，不再赘述。
S603，RAN向选择的AMF发送注册请求以及ULI。
相应地，AMF接收来自AMF的该注册请求以及ULI。
该ULI中包括RAN覆盖的多个地理位置的标识(为了方便描述，记为第一地理位置标识)。
该地理位置的范围小于TA的范围。例如，该地理位置可以是某省、某市、某县、某镇或者某街道等。该地理位置的标识可以是省、市、县、镇或者街道对应的码(code)。
可以理解，本申请以行政区域表示地理位置仅为示例，地理位置还可以有其他表示形式，本申请不做限定。
S604，AMF从UDM获取UE的签约数据。
该签约数据中包括UE的移动性限制区域的信息。该UE的移动性限制区域可以包括至少一个地理位置，UE的移动性限制区域的信息包括该至少一个地理位置的标识(为了简便，记为第二地理位置标识)。
例如，该至少一个地理位置包括禁止区域和/或“不允许区域”对应的地理位置。即UE在该至少一个地理位置中的访问、或移动受限。
也就是说，UE的签约数据中的移动性限制区域可以不是以TA为粒度划分的，而是以地理位置为粒度划分的，该地理位置的范围小于TA的范围。
需要说明的是，属于UE的移动性限制区域的地理位置的范围可以大于或等于，RAN覆盖的地理位置的范围。
例如，RAN覆盖的地理位置可以是镇粒度的，或者城市粒度，UE的移动性限制区域的地理位置可以是城市粒度的。
S605，判断第一地理位置标识与第二地理位置标识是否存在交集，且第一地理位置标识不是第二地理位置标识的子集。
若不是，则按照现有的方案执行UE的移动性限制。
若是，则执行后续步骤。
需要说明的是，当属于UE的移动性限制区域的地理位置的范围大于，RAN覆盖的地理位置的范围时，AMF可以通过判断第一地理位置标识对应的地址位置是否属于第二地理位置标识对应的地理位置来判断第一地理位置标识与第二地理位置标识是否存在交集。
例如，第二地理位置标识对应的地理位置为城市，第二地理位置标识包括城市#1的标识，第一地理位置标识对应的地理位置包括镇，第一地理位置标识包括镇#1的标识，AMF可以判断镇#1是否属于城市#1，如果属于，则第一地理位置标识与第二地理位置标识存在交集。
在执行后续步骤前，AMF可通过RAN向UE发送注册接受请求。
S606，AMF向LMF发送定位请求。
相应地，LMF接收来自AMF的该定位请求。
该定位请求可以携带指示信息#1，该指示信息#1指示定位模式。该定位请求携带的其他信息以及该定位请求的具体形式可以参考S506中的描述。
该指示信息#1和S506中的指示信息#1类似，不再赘述。
S607，LMF执行定位流程。
根据选择的定位模式的不同，LMF执行定位流程包括两种情况。分别参考S507中的情况一和情况二。
可选地，S608，LMF确定UE的位置估计。
该步骤和S514类似，不再赘述。
S609，LMF确定UE的位置信息并向AMF发送定位响应。
例如，该定位响应可以是Nlmf_Locaion_Determine Location Response。
该定位响应携带该UE的位置信息。根据UE的位置信息的不同，S608具体分为两种情况。
情况一：
S609a，LMF将UE的位置估计映射为UE所在的地理位置对应的地理位置标识。
UE所在的地理位置对应的地理位置标识与第一地理位置标识的粒度可以相同，或者，相较于第一地理位置标识的粒度，该UE所在的地理位置对应的地理位置标识的粒度可以更细。
S609b，LMF向AMF发送定位响应，该定位响应携带该UE所在的地理位置对应的地理位置标识。
相应地，AMF接收来自LMF的定位响应。
情况二：
S609c，LMF向AMF发送定位响应，该定位响应携带UE的位置估计。
相应地，AMF接收来自LMF的该定位响应。
以上两种情况中，可选地，该定位响应还可以携带LMF所采用的定位模式。AMF可参考LMF返回的采用的定位模式确定该位置估计的可靠程度。
对应情况二，该方法还可以包括S610，AMF将UE的位置估计映射为UE所在的地理位置对应的地理位置标识。
S611，AMF根据UE所在的地理位置对应的地理位置标识，以及第二地理位置标识确定是否对该UE实施移动性限制。
示例性地，AMF可以查询该UE所在的地理位置对应的地理位置标识是否为第二地理位置标识中的标识，如果是，则AMF执行UE的移动性限制。例如，如果该UE所在的地理位置属于移动性签约 数据中的禁止区域，则AMF发起解注册流程或拒绝UE的注册请求。
基于上述方案，在第一地理位置标识中部分地理位置标识属于第二地理位置标识的情况下，AMF可以通过调用定位服务，确定UE当前所在的地理位置，并根据UE当前UE所在的地理位置以及移动性限制签约数据来判断是否执行UE的移动性限制，从而可以防止该UE绕过移动性限制。
更进一步地，基于上述方案，通过将UE所属的区域划分为更细的粒度(相较于TA而言)，可以避免因为卫星波束覆盖面积较大，在为卫星接入网络规划TA时其面积大小可能相比地面接入网络的TA面积要大，而导致地移动性限制粒度不够精细的问题。
