随着“任意时间、任意地点”的通信概念的提出，卫星通信，即非地面通信(non-terrestrial network,NTN)凭借通信范围大，可靠性高，多址连接等特点从19世纪60年代至今一直是研究领域的热门。通常来说，卫星的轨道越高其覆盖面积越大，但是通信的时延也越长。一般说来，卫星的运行轨道根据高度可以分为：
(1)低轨道(low earth orbit,LEO)：轨道高度为160～2000km；
(2)中轨道(medium earth orbit,MEO)：轨道高度为2 000～35786km；
(3)地球同步轨道(geosynchronous earth orbit,GEO)或者称为静止轨道：轨道高度为35786km，运行在此轨道上的卫星与地球的相对位置不受地球自转的影响。

具体实施方式
为了更清楚、完整介绍本申请的技术方案，以下结合附图对本申请实施例进行说明。
图1A为本申请实施例适用的一种网络架构100示意图。如图1A所示，终端(图中示出终端110)可接入到无线网络或者称为与无线网络进行通信，以通过无线网络获取外网(例如因特网)的服务。该无线网络包括网络设备(或者说无线接入网(radio access network，RAN)设备，图中示出网络设备120)，其中网络设备120用于将终端110接入到无线网络。 可选的，网络设备120可以是卫星或卫星设备。可选的，终端110可以通过无线接口(如Uu口)与网络设备120进行通信。
应理解，图1A所示的通信系统中各个设备的数量仅作为示意，本申请实施例并不限于此，实际应用中在通信系统中还可以包括更多的终端110、更多的RAN设备，还可以包括其它设备。例如，虽然未示出，但除图1A所示网络功能实体外，图1A所示的网络架构100还可以包括其他功能实体，如：核心网网元等，本申请不予限制。
图1A中的终端设备可以是能够接收网络设备调度和指示信息的无线终端设备，无线终端设备可以是指向用户提供语音和/或数据连通性的设备，或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备可以经无线接入网(如，radio access network，RAN)与一个或多个核心网或者互联网进行通信，终端设备可以为用户设备(user equipment，UE)。终端设备也可以是移动终端设备，如移动电话(或称为“蜂窝”电话，手机(mobile phone))、计算机和数据卡，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。无线终端设备也可以称为系统、移动站(mobile station)、移动台(mobile station，MS)、远程站(remote station)、接入点(access point，AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户站(subscriber station，SS)、用户端设备(customer premises equipment，CPE)、终端(terminal)、用户设备(user equipment，UE)、移动终端(mobile terminal，MT)等。终端设备也可以是可穿戴设备(智能手表、智能手环等)，还可以为智能家具(或家电)、车联网中的汽车、工业互联网中的机械手臂、智能加油设备等以及下一代通信系统，例如，第五代(5th generation，5G)通信系统中的终端设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的终端设备等。中继设备也可以是路边的基础设施。
图1A中的网络设备可以是无线网络中的设备，例如包括接入网设备，和/或核心网设备。例如接入网设备可以为将终端接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)，又可以称为基站。目前，一些RAN设备的举例为：5G通信系统中的新一代基站(generation Node B，gNodeB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、节点B(Node B，NB)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wi-Fi)接入点(access point，AP)等。另外，在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备。此外，在其它可能的情况下，网络设备可以是其它为终端设备提供无线通信功能的装置。例如，网络设备可以是卫星。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述，本申请实施例中，为终端设备提供无线通信功能的装置称为网络设备或接入网设备。核心网设备可以用于实现移动管理，数据处理，会话管理，策略和计费等功能。不同接入技术的系统中实现核心网功能的设备名称可以不同，本申请并不对此进行限定。以5G系统为例，所述核心网设备包括：访问和移动管理功能(access and mobility management function，AMF)、会话管理功能(session management function，SMF)、或用户面功能(user plane function，UPF)等。
上述图1A所示意的网络架构可以适用于各种无线接入技术的通信系统中，例如可以是 长期演进(long term evolution,LTE)通信系统，也可以是5G(或者称为新无线(new radio，NR)通信系统，也可以是LTE通信系统与5G通信系统之间的过渡系统，该过渡系统也可以称为4.5G通信系统，当然也可以是未来的通信系统。本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，即不限于NTN网络，不限于LEO，GEO卫星，也不限于存在广播机制的通信系统，本领域普通技术人员可知，随着通信网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
需要说明的是，上述图1A架构中的网元、各个网元之间的接口名字以及各个协议栈的命名只是一个示例，具体实现中网元、网元之间的接口名字以及协议栈能为其他名字，本申请实施例对此不作具体限定。
以下示例性的列举几种可能的系统架构或场景。
图1B为本申请实施例适用的又一种网络架构示意图。如图1B所示，该透明架构(RAN architecture with transparent satellite)下，卫星在上行链路和下行链路上实现频率转换和射频放大器。卫星从反馈链路(例如NTN网关和卫星之间)到业务链路(例如卫星和终端之间)重复NR-Uu无线接口，反之亦然。卫星主要是作为层1中继(L1relay)，将物理层信号重新生成，高层不可见。不同的透明(transparent)卫星可能在地面连接到同一个接入网设备(例如，基站)，多个基站也可以访问同一个透明卫星。
本申请实施例适用的网络架构也可以是卫星再生架构、带星链的再生架构、卫星是分布式单元的再生架构等，例如卫星设备(如LEO)作为独立基站，与地面核心网设备相连。或者，LEO作为DU，与地面CU相连。或者，LEO作为中继基站，与地面基站相连。本申请实施例并不限定。
在移动通信系统中，终端可以处于不断移动的状态，网络设备可以根据终端的业务进行情况来转换终端的状态，并在终端移动的时候，获取终端位置信息、保证数据传输的连续性等，对终端进行移动性管理。
网络的移动性管理既要保证终端可达和数据传输连续，又要防止终端接入某些受限区域或者请求不该使用的服务。移动性限制可以是指终端的接入访问受限、移动受限等。移动性限制可以包括RAT restriction、禁止区域、服务区域限制、核心网类型限制四种：
RAT restriction信息一般用于指示与接入技术关联的限制信息。
禁止区域信息主要是用于指示在该区域内不允许终端与网络通信。
服务区域信息一般包括允许服务区和非允许服务区，允许服务区用于指示在该区域内能给终端提供正常的通信服务，非允许服务区用于指示在该区域内能给终端提供受限的通信服务。
核心网类型限制信息一般包括不允许接入的核心网类型信息。
移动性限制的概念和说明以及终端对应的行为可以示例性的参考第三代合作伙伴计划(3rd generation partnership project，3GPP)TS23.501 v 16.3.0章节5.3.4.1的内容。需要说明的是，本申请引用的3GPP标准协议的内容可能发生变化，并不意味着脱离了本申请方案的适用范围。
在一些场景下，一个小区可以覆盖多个跟踪区域码(tracking area code，TAC)，例如，在卫星通信场景下，因为LEO卫星飞行且小区大，半径可达1000KM，一个NTN小区可 以覆盖多个TAC。
一种可能的方式中，终端通过读取小区系统广播中的TAC与移动限制信息中的TAC比较后进行移动性通信。例如，终端在比较后确定终端在禁止区域，终端可以确定不驻留任何小区，或者，终端在比较后确定终端不在禁止区域，终端可以确定驻留某个合适的小区。
当一个小区覆盖多个TAC时，容易出现限制信息(如限制区域，限制区域可以包括禁止区域，服务区域等)不准确的问题，例如限制区域被扩大或被缩小。以限制区域为禁止区域为例，该小区覆盖的多个TAC可能部分属于禁止区域，部分不属于禁止区域。如果广播的多个TAC中有一个属于禁止区域，则禁止终端接入，会导致禁止区域被扩大。
如图1C所示，例如TAC3是UE1的禁止区域，如果广播的多个TAC中有一个属于禁止区域，则禁止终端接入，在时刻1(T1)该NTN小区覆盖TAC1至TAC3，禁止区域扩大成TAC1至TAC3，在时刻2(T2)该NTN小区覆盖TAC2至TAC4，禁止区域扩大成TAC2至TAC4。但可能UE1在T1至T2的期间内，UE1一直在TAC2，不应该被禁止接入，限制区域被扩大，导致移动性管理性能降低，终端通信体验较差，终端难以得到良好的通信服务。另外，不同的卫星的轨迹不同，可能从不同的方向飞来，一个NTN小区覆盖的多个TAC可以也在变化，这种限制区域扩大影响通信服务的质量。
容易理解的，如果广播的多个TAC中全部属于禁止区域，才禁止终端接入，会导致禁止区域被缩小。
如何提升移动性限制功能的性能，例如，提升限制区域的准确性是亟需解决的问题。
图2为本申请实施例提供的一种移动性限制通信方法200，用于提升移动性限制功能的性能，改善通信体验。该方法可以由设备、模块或单元之间交互执行。例如，该方法可以由第一模块和第二模块之间或者第一模块与第一单元之间，或者第一单元与第二单元之间交互执行。该方法也可以由网络设备和终端交互执行，当然也可以是网络设备和终端的部件之间交互执行，例如模块、单元、芯片或芯片系统。示例性的，网络设备为无线接入网络设备，终端与无线接入网设备间建立有无线通信接口，例如LTE空口或者NR空口。为了便于介绍，在下文中，以该方法由网络设备或终端执行为例，如图2所示，该方法200可以包括：
S210：第一网络设备向终端发送移动性限制信息。
相应的，终端接收来自第一网络设备的移动性限制信息，该移动性限制信息包括第一位置信息，该第一位置信息包括与禁止区域、允许服务区域与非允许区域中的至少一项对应的位置信息。
可选的，移动性限制信息包括第一位置信息可以理解为，移动性限制信息包含的一项或多项信息(为描述方便，可简称为限制区域信息)与位置信息关联或者对应。例如，限制区域信息可以包括禁止区域信息，该禁止区域信息与位置信息关联，也就是说，可以根据该位置信息判断是否处于禁止区域。
可以理解的，本申请以该信息为移动性限制信息为例进行介绍，本申请并不限定信息的名称，例如，移动性限制信息也可称为配置信息或者指示信息。所述移动性限制信息可以是通信标准中已定义的移动性限制信息，所不同的是，移动性限制信息还包括第一位置信息。移动性限制信息也可以是通信标准中新定义的移动性限制信息。容易理解的，本申请实施例并不限定移动性限制信息中是否包含跟踪区域码。
可选的，位置信息可以称为地理信息或地理位置信息。
可选的，位置信息包括位置范围信息。例如，第一位置信息包括位置范围信息，第二位置信息包括位置范围信息。示例性的，该位置范围信息可以用于表征一个区域的位置，也就是说，位置范围信息也可称为位置区域信息。本申请并不限定表征位置范围的具体实现方式，例如，禁止区域对应的第一位置信息为位置范围1，位置范围1可以是矩形区域，位置范围1可以用该矩形的四个顶点表征。
示例性的，位置信息可以是绝对位置信息或者实际物理位置信息，例如位置信息包括经纬度信息。该位置信息也可以是相对位置信息，例如相对于其他网元、参照物或设备的位置信息。
一种可能的方式中，该位置信息还可以包括时间信息，即，该位置信息与时间信息关联或对应。或者说，移动性限制信息与时间信息关联。例如，第一位置信息包含时间信息，其中，该时间信息可以用于表征与移动性限制信息对应的位置信息是与时间关联的，例如，禁止区域对应的位置信息与时间信息相关。包含时间信息的位置信息能够更加准确的反映移动性限制信息，提升移动性管理的性能，例如可以应用到卫星小区会移动的场景中。
可以理解，移动性限制信息与第一位置信息的关联关系有多种不同的实现方式。例如，可以是以表格的形式实现，也可以采用函数的形式实现，还可以采用其他的数据结构实现，例如可以采用数组、队列、容器、栈、线性表、指针、链表、树、图、结构体、类、堆、散列表或哈希表等实现。
示例性的，移动性限制信息与第一位置信息的关联关系可以由表1示出。
表1
禁止区域 位置1或位置范围1
服务区域 位置2或位置范围2
非服务区域 位置3或位置范围3
核心网限制信息 位置4或位置范围4
表1中，示例性的列举了移动性限制信息中包含的一些信息与位置信息的对应关系，本申请并不限定移动性限制信息仅包括这些信息或者必须包含这些信息，仅是作为示例。例如，禁止区域对应位置1或位置范围1，也就是说，当终端的位置位于位置1或位置范围1时，确定终端处于禁止区域。容易理解的，表1中仅为一种示例，并不限定，例如，考虑到卫星小区可能会移动，该位置信息还可以包括时间信息，如位置1还可以与时间信息1对应。
所述移动性限制信息可以承载于广播消息(例如小区系统广播消息)，无线资源控制(radio resource control，RRC)消息、媒体接入控制(media access control，MAC)控制元素(control element，CE)或下行控制信息(downlink control information，DCI)等消息中发送给终端。示例性的，移动性限制信息和第一位置信息可以在一条消息中发送，例如，移动性限制信息中携带第一位置信息，或者，也可以在不同的消息中发送。
一种可能的方式，第一网络设备周期性的向终端设备发送移动性限制信息。
示例性的，本申请并不限定第一网络设备如何获取或确定该移动性限制信息，例如，一种可能的方式中，第一模块或第一单元向第一网络设备发送移动性限制信息，相应的，第一网络设备接收第一模块或第一单元发送的移动性限制信息。所述第一模块根据所述移 动性限制信息与所述第一网络设备进行移动性通信。容易理解的，移动性通信可以理解为，该移动性限制信息用于确定终端对应的限制区域，限制区域包括移动性限制信息对应的区域。
可选的，该第一模块或第一单元具有移动性管理功能。示例性的，该第一模块或第一单元为核心网设备，本申请实施例并不限定。例如，又一种可能的方式中，第一网络设备确定移动性限制信息。
可选的，终端处于RRC连接态时接收第一网络设备发送的移动性限制信息。
可选的，S210中的第一网络设备向终端发送移动性限制信息可以是发送用于指示移动性限制信息的指示信息，根据该指示信息，终端可以确定移动性限制信息。
容易理解的，S210为终端获取移动性限制信息的一种示例。可选的，终端具有其他多种获取移动性限制信息的实现方式。因此S210是可选的步骤，即S210可以被替换成其他终端获取移动性限制信息的方式。一种可能的方式中，终端从其他网元设备获取该移动性限制信息，例如，终端从中继终端或者其他终端接收移动性限制信息。再一种可能的方式中，该移动性限制信息是预定义的或者是预配置的。其中，关于移动性限制信息的相关介绍(例如位置信息的内容)可以参考S210中的描述，所不同的是，移动限制信息是预定义的或者是预配置的。
S220：根据移动性限制信息和第二位置信息进行移动性通信，其中，第二位置信息包括该终端的位置信息。
容易理解的，S220中的进行移动性通信可以称为进行移动性管理，或者，进行移动性判断。
