技术领域
本申请涉及无线通信技术领域，尤其涉及一种通信控制方法及通信装置。
背景技术
随着高精度定位技术的发展和应用，越来越多的场景需要高精度定位技术提高管理和生产效率。比如，通过高精度定位系统，可为无人机提供实时高精度的位置信息、航行姿态、速度信息、精准时间信息等；或者，通过高精度定位服务，可实现自动驾驶或室内导航等。并且，随着半导体技术的发展，终端设备具有越来越多的形态。由于不同终端设备具有不同的功能和不同的应用场景，一些场景中，终端设备与终端设备的相对距离成为不可忽视的考虑因素。例如，一些危险的工业设备中，这些设备附近不允许有其他设备进行工作，避免存在通信干扰。又例如，无人驾驶巡检车在巡检过程中，车上的巡检装置和测量装置准确安装在无人驾驶车辆上，才能保证测量数据的准确。

终端设备、(无线)接入网与核心网是构成上述网络架构的主要部分，逻辑上它们可以分为用户面和控制面两部分，控制面主要负责移动网络的管理，用户面主要负责业务数据的传输。示例性地，如图1a所示，在5G通信系统中，下一代(next generation，NG)2参考点位于(无线)接入网控制面与核心网控制面，NG3参考点位于(无线)接入网用户面与核心网用户面，NG6参考点位于核心网用户面与数据网络。
下面对上述网络架构的各个组成部分进行详细介绍。

终端设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。本申请实施例对终端设备所采用的具体技术、设备形态、应用场景以及名称不作限定。
2、(无线)接入网，部署在靠近终端设备的位置，为特定区域的授权用户提供入网功能，并能够根据用户的级别、业务的需求等确定不同质量的传输隧道来传输用户数据。(无线)接入网能够管理并合理利用自身的资源，按需为终端设备提供接入服务，并负责把控制信号和业务数据在终端设备和核心网转发。

图2示出了本申请实施例适用的一种更为具体的网络架构，该网络架构可以是5G通信系统的网络架构。如图2所示，该网络架构中包括终端设备、接入网设备、各种类型的核心网网元/功能实体以及数据网络。
其中，核心网用户面包括用户面功能(user plane function，UPF)。核心网控制面包括但不限于：接入和移动性管理功能(access and mobility management function，AMF)网元、会话管理功能(session management function，SMF)网元、认证服务器功能(authentication server function，AUSF)网元、网络切片选择功能(network slice selection function，NSSF)网元、网络开放功能(network exposure function，NEF)网元、网络功能仓储功能(network function repository function，NRF)网元、策略控制功能(policy control function，PCF)网元、统一数据管理(unified data management，UDM)网元、应用功能(application function，AF)网元、位置管理功能(location management function，LMF)网元、网络切片认证和授权功能(network slice specific authentication and authorization function，NSSAAF)网元。
具体的，AMF网元主要负责终端设备的接入管理和移动性管理，例如负责终端设备的状态维护、终端设备的可达性管理、非移动性管理接入层(mobility management non-access-stratum，MM NAS)消息的转发、会话管理(session management，SM)N2消息的转发。
SMF网元主要负责移动网络中的会话管理，包括为终端设备建立会话、为会话分配和释放资源，其中资源包括会话服务质量(quality of service，QoS)、会话途径、转发规则等。例如，为终端设备分配互联网协议(internet protocol，IP)地址、选择提供报文转发功能的UPF网元等。
UPF网元主要负责连接外部网络，根据SMF的路由规则执行用户数据包转发，如上行数据发送到数据网络或其它UPF网元，下行数据发送到其它UPF网元或者接入网设备。
AUSF网元主要负责执行终端设备的安全认证。
NSSF网元主要负责为终端设备的业务选择合适的网络切片。
NEF网元将网络的部分功能有控制地暴露给应用。
NRF网元主要负责为其他网元提供网络功能实体信息的存储功能和选择功能。
PCF网元主要负责用户策略管理，包括策略授权、服务质量以及计费规则的生成，并将相应规则通过SMF网元下发至UPF网元，完成相应策略及规则的安装。
UDM网元主要负责管理用户数据，包括签约信息、上下文、策略信息等。应注意，尽管在图2中暂未示出，图2中所示的网络架构中还可包括统一数据仓储(unified data repository，UDR)网元，并且UDM网元的功能可以通过与UDR网元的交互实现。其中，UDR网元用于存储UDM网元执行其操作时所需的数据，UDM网元用于与其他网元进行 交互。实际实现时，UDM网元和UDR网元可以是两个独立的物理实体，UDR网元也可集成在UDM网元中，并不限定。

作为示例，在图2所示的网络架构中，终端设备与AMF网元的接口称为N1接口，接入网设备与AMF网元的接口称为N2接口，接入网设备与UPF网元的接口称为N3接口，UPF网元与SMF网元的接口可以称为N4接口，UPF网元与数据网络的接口称为N6接口。当然，在未来的通信系统中，这些接口的名称可以不变，或者也可以用其他名称代替，本申请对此不限定。
在未来的通信系统如第六代(6th generation，6G)通信系统中，上述网元或设备仍可以使用其在第四代(4th generation，4G)或5G通信系统中的名称，或者有其它名称；上述网元或设备的功能可以由一个独立网元完成，也可以由若干个网元共同完成，本申请实施例对此不作限定。
在实际部署中，上述网元可以合设。例如，接入和移动性管理功能网元可以与会话管理功能网元合设；会话管理功能网元可以与用户面功能网元合设。当两个网元合设的时候，本申请实施例提供的这两个网元的交互就成为该合设网元的内部操作或者可以省略。
需要说明的是，核心网控制面可以采用服务化架构，各个控制面网元连接到一条服务总线上，控制面网元的交互采用服务调用的方式，来替换传统的核心网架构中的点对点通信方式。服务化架构中，控制面网元会向其他控制面网元开放服务，供其他控制面网元调用。点对点通信中，控制面网元通信接口会存在一套特定的消息，只能由接口两端的控制面网元在通信时使用。
需要说明的是，上述各种可能的网络架构中的网元/功能实体既可以是硬件设备中的网络元件，也可以是在专用硬件上运行的软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。可选的，上述网元或者功能实体可以由一个设备实现，也可以由多个设备共同实现，还可以是一个设备内的不同的功能模块，本申请实施例对此不作具体限定。
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，本领域普通技术人员可知，随着通信系统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。
本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C，A和B，A和C，B和C，或A和B和C。同理，对于“至少一种”等描述的理解，也是类似的。“以下至少一项(个)”或其类似表达，是指这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如“A，B和C中的至少一个”包括A，B， C，AB，AC，BC或ABC。“和/或”，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，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有特别说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度，并且“第一”、“第二”的描述也并不限定对象一定不同。
目前，高精度定位技术的应用场景越来越多。因此，获取终端设备的高精度位置信息发挥着越来越重要的作用。图3示出的为一种获取UE位置信息的交互流程示意图。示例性的，图3中示出的应用场景可以包括以下交互流程：
步骤301a、5G核心网(5G core network，5GC)中的实体1可以向AMF网元发起位置服务请求。例如，实体1可以为网关移动定位中心(gateway mobile location center，GMLC)，发起位置服务请求具体可以为请求目标UE的位置服务，例如定位等。
步骤301b、AMF网元确定对目标UE的位置服务请求。例如，AMF网元可以在目标UE紧急呼叫时，对目标UE进行定位。
步骤301c、UE向AMF网元发起位置服务请求。例如，若UE需要基于位置服务进行通信的场景下，通常需要向AMF网元请求位置服务。
需要说明的是，步骤301a至步骤301c中任一步骤均可作为请求UE的位置服务的触发条件。
步骤302、AMF网元可以向LMF网元转发位置服务请求。
步骤303a、LMF网元可与NG-RAN中的节点1发起定位过程；例如进行定位测量或者传输位置辅助数据等。其中，节点1例如可以为gNB。可选的，若LMF网元采用的定位方式需要NG-RAN的配合，LMF网元可与NG-RAN中的节点1进行交互，以实现对目标UE的定位过程。可以理解，若LMF网元采用的定位方式不需要NG-RAN的配合，则无需与NG-RAN中的节点1进行交互。
步骤303b、LMF网元可与UE发起定位过程；例如进行位置估计或者进行定位测量等。可选的，若LMF网元采用的定位方式需要UE的配合，LMF网元可向UE请求辅助，以实现定位过程。可以理解，若LMF采用的定位方式不需要UE的配合，则无需向UE请求辅助。
步骤304、LMF网元向AMF网元返回位置服务响应。示例性的，位置服务响应可以包括：位置服务成功、或者位置服务失败、或者UE的位置估计等信息。
步骤305a、对应步骤301a的触发场景，AMF网元向5GC中的实体1返回所述位置服务响应消息。
步骤305b、对应步骤301b的触发场景，AMF网元根据所述位置服务响应对位置服务请求进行处理。
步骤305c、对应步骤301c的触发场景，AMF网元向UE返回所述位置服务响应消息。
结合上述内容，在图3介绍的获取UE的位置信息的流程下，相关技术中核心网对UE的通信控制，通常可以是基于UE的绝对位置信息。由于基于UE的绝对位置信息进行通信控制的控制方式已经无法满足现在的一些控制场景的需求，目前也可以考虑基于UE与另一UE(本申请实施例中也可称为“绑定UE”)的相对位置信息实现对UE的通信控制。 因此，如何准确地确定与UE相关的绑定UE，是值得研究的。
有鉴于此，本申请实施例提供一种通信控制方法。该方法中，核心网中的网元可以从多个备选UE中选择或重选绑定UE。进一步的，核心网中的网元可以基于UE和绑定UE的相对位置信息，对UE进行通信控制，从而可以提升对UE进行通信控制的精度和灵活性，以及可以满足更多应用场景下的业务需求。其中，本申请可以预先定义与UE相关的一个或多个备选UE，并预先设置在控制指示信息中，或者本申请还可以基于预先设置的目标区域范围，然后可以将从所述目标区域范围中筛选得到UE作为备选UE。
以下对本申请实施例提供的一种通信控制方法进行详细介绍。需要说明的是，以下实施例中以核心网中的网元对第一终端设备进行通信控制作为示例。此外，本申请实施例中，若核心网中的网元也需要对目标终端设备进行通信控制，则对目标终端设备进行通信控制的实现过程可参阅对所述第一终端设备进行通信控制的过程，本申请对此不再赘述。需要说明的是，本申请实施例中以基于5G通信系统的网络架构，以及第一网元、第二网元、第三网元等网元以5G通信系统中对应的网元作为示例进行介绍；可以理解，随着系统架构演变和新业务场景出现实施例提供的技术方案同样适用。
图4为本申请实施例中提供的一种通信控制方法的交互流程示意图。该交互流程可以包括：
S401、第一网元从第二网元中获取第一终端设备的控制指示信息。其中，所述控制指示信息可预先配置在第二网元中，或者所述控制指示信息也可以由所述第二网元为所述第一终端设备生成的。
一种可能的触发场景为，若所述第一网元接收到所述第一终端设备发送的请求信息，所述第一网元可以基于所述请求信息，从所述第二网元获取第一终端设备的控制指示信息。其中，所述请求信息可用于请求所述第一网元所管理的服务或者还可用于请求接入所述第一网元所服务的网络。其中，所述第一网元所服务的网络可以包含一个或多个切片，若所述第一网元包含多个切片时，所述第一终端设备可以请求接入所述第一网元中的一个切片。可以理解，若第一网元不允许所述第一终端设备接入请求的切片时，所述第一终端设备无法接入该切片，但不影响第一终端设备接入所述第一网元服务的其他切片。
示例性的，第一网元可以为AMF网元、或SMF网元。可选的，所述第一终端设备发送的请求信息可以为在UE已经在核心网中注册之后，UE启动PDU会话建立流程。可实施为，UE向AMF网元发送的会话建立请求；然后AMF网元可将UE发起发送的会话建立请求转发给SMF网元继续处理。另一可选的，所述第一终端设备发送的请求信息还可以为UE请求接入AMF网元所服务的切片请求。
示例性的，第二网元可以为UDM网元、或AF网元、或PCF网元。基于所述控制指示信息可预先配置在第二网元中，在第一网元向第二网元获取第一终端设备的相关信息时，所述控制信息可携带于所述第一终端设备的相关信息中。本申请实施例中，AMF网元或SMF网元响应于UE的请求信息，可以从UDM网元中获取UE的签约信息，或者也可以从AF网元中获取可扩展认证协议(extensible authentication protocol，EAP)消息，又或者还可以从PCF网元中获取策略控制消息。
一种可选的实施例中，所述控制指示信息可携带于所述UE的签约信息中。例如，图5a示出的为本申请实施例提供的一种获取控制指示信息的流程示意图。其中，图5a可以 包括以下交互流程：
步骤501、目标终端设备(以下各实施例中可简称为“UE0”)建立会话；其中，所述UE0已经在网络中注册。示例性的，第一网元对第一终端设备进行通信控制之前，第一终端设备对应的目标终端设备可以已经在核心网中建立有会话。并且，在目标终端设备建立会话过程中，可以实现开启目标终端设备的绑定功能，以实现根据目标终端设备，对第一终端设备的通信控制。
可以理解，在第一终端设备确定目标终端设备之前，可能作为第一终端设备的目标终端设备的一个或多个备选终端设备可以均开启绑定功能，以实现可作为第一终端设备的目标终端设备(本申请实施例中也可称为“绑定UE”)；其中，如果开启绑定功能的备选终端设备与第一终端设备的相对位置信息满足控制指示信息中的控制条件，则可被确定为绑定UE。其中，备选终端设备开启绑定功能可实施为备选终端设备发起会话建立请求过程中，可以携带PDU会话类型(session type)消息，所述PDU session type消息可用于标识此会话是用于开启备选终端设备的绑定功能；或者，所述PDU session type消息也可以预先存储在UDM网元管理的备选终端设备的上下文信息中，或预先存储在AF网元或PCF网元中。这样，第一网元通过备选终端设备的请求或者核心网的网元的预先配置等方式确定开启备选终端设备的绑定功能。另外，备选UE开启绑定功能的同时还可标记备选UE的终端设备类型，例如所述PDU session type消息中可以携带终端设备类型。
步骤502、第一终端设备(以下实施例中简称为“UE1”)向AMF网元发起会话建立请求，AMF网元将UE1的会话建立请求转发给SMF网元。其中，所述UE1已经在网络中注册。
步骤503a、SMF网元获取UE1的签约信息。其中，在UE1的签约信息中可以携带UE1的控制指示信息。
另一种可选的实施例中，所述控制指示信息还可携带于所述UE的EAP消息。例如，图5b示出的为本申请实施例提供的另一种获取控制指示信息的流程示意图。其中，图5b可以包括以下交互流程：
步骤501、UE0建立会话。
步骤502、UE1向AMF网元发起会话建立请求，AMF网元将UE1的会话建立请求转发给SMF网元。其中，所述UE1已经在网络中注册。
步骤503b、UE1进行二次认证。示例性的，若UE1需要与第三方服务网络进行交互，管理UE1的核心网网元通常需要向AF网元请求二次认证，若二次认证通过，UE1可继续实现对第三方服务网络进行数据访问或数据处理等；若二次认证未通过，则UE1无法继续实现对第三方服务网络进行数据访问或数据处理等。
步骤504b、SMF网元获取UE1的EAP消息。其中，若UE1的二次认证通过，在UE1的EAP消息中可以携带UE1的控制指示信息。例如，所述EAP消息可以为EAP成功(success)消息。
另外，在其他可选的实施例中，所述控制指示信息也可携带于所述UE的策略控制消息中，或还可携带其他消息中，本申请对此不进行限定。
此外，第一网元还可从本地存储中获取到所述第一终端设备的控制指示信息，此时所述第二网元可理解为所述第一网元自身，也即所述第二网元也可以为AMF网元或SMF网 元。可以理解，所述第二网元还可以为其他网元，例如未来通信系统中扩展的可存储控制指示消息的任一网元或功能实体等，本申请对此不进行限定。
可选的，所述控制指示信息中可以包含通信控制条件，所述通信控制条件用于指示核心网的网元是否开启对第一终端设备的通信控制。示例性的，若所述通信控制条件指示开启通信控制，则第一网元开启对所述第一终端设备的通信控制流程；若所述通信控制条件指示关闭通信控制，则所述第一网元不进行对所述第一终端设备的通信控制流程，或者若所述第一网元正在对所述第一终端设备进行通信控制，则停止对所述第一终端设备的通信控制流程。
S402a、所述控制指示信息中包括多个第二终端设备的设备标识，所述第一网元根据所述第一终端设备与所述多个第二终端设备中的至少一个第二终端设备的相对位置信息，从所述至少一个第二终端设备中确定目标终端设备。
在一些可能的场景中，为了便于为UE选择或者重选绑定UE，可以为UE预先配置可能作为绑定UE的备选UE的列表。本申请实施例中，在预先配置的控制指示信息时，可以将多个备选UE的设备标识配置在控制指示信息中。也即所述控制指示信息可包含多个第二终端设备的设备标识，所述多个第二终端设备可以作为第一终端设备的多个备选UE。例如，若第二网元为UDM网元，第二终端设备的设备标识可以通过终端设备的用户永久标识(subscription permanent identifier，SUPI)来表示。又例如，若第二网元为AF网元，第二终端设备的设备标识可以通过终端设备的一般公共订阅标识符(generic public subscription identifier，GPSI)来表示；其中，核心网设备接收到第二终端设备的GPSI标识之后，可以从UDM网元中获取GPSI和SUPI的对应关系，从而将GPSI标识更换为SUPI标识，以便于核心网设备的处理。需要说明的是，本申请不限定第二终端设备的设备标识的表示形式，其他可能的形式也可适用于本申请实施例，例如第二终端设备标识还可以为预先自定义的其他终端设备标识等。
本申请实施例中，针对任一第二终端设备，若所述第一网元确定所述第一终端设备与所述第二终端设备的相对位置信息满足所述控制指示信息中还包括的控制条件，确定所述第二终端设备为目标终端设备。因此，可以通过UE与备选UE的相对位置信息，判断备选UE是否满足绑定UE的条件，从而可以从多个备选UE中选择或者重选绑定UE。
示例性的，所述控制条件可包括但不限于以下条件中至少一种：
1)所述第一终端设备和第二终端设备的相对距离在预设距离范围内。
可选的，预设距离范围可以为小于预设距离阈值；此时，若第二终端设备与第一终端设备的相对距离小于预设距离阈值，则第二终端设备可确定为目标终端设备，反之第二终端设备不可确定为目标终端设备。
另一可选的，预设距离范围还可以为大于或等于预设距离阈值；此时，若第二终端设备与第一终端设备的相对距离大于或等于预设距离阈值，则第二终端设备可确定为目标终端设备，反之第二终端设备不可确定为目标终端设备。
2)所述第一终端设备和第二终端设备的相对方向在预设方向范围内。示例性的，预设方向范围可为以第一终端设备相关的某一标准方向(例如正北、正南、正前等方向)为基准所涉及的预设方向角。例如，若第二终端设备存在于所述预设方向范围内，则第二终端设备可确定为目标终端设备，反之第二终端设备不可确定为目标终端设备。
一种可能的示例中，若所述控制条件包括上述预设距离范围和预设方向范围，则控制条件可以为，所述第一终端设备和目标终端设备的相对距离≥1米，并且所述第一终端设备和目标终端设备的相对方向在第一终端设备正前方90°范围内。
需要说明的是，不同第二终端设备对应相同或者不同的控制条件，具体实施时可根据实际场景进行设置。例如，相同类型的第二终端设备可以对应相同的控制条件，而不同类型的第二终端设备可以对应不同的控制条件。
此外，所述第一网元还可从所述控制指示信息中或从本地存储中或自动生成等方式，获取到所述多个第二终端设备的优先级。基于所述多个第二终端设备的优先级，可分别实现以下多种确定目标终端设备的确定方式，如下：
确定方式A1、所述第一网元可以根据所述多个第二终端设备的优先级，依次获取所述第一终端设备与所述第二终端设备(以下各实施例中可简称为“UE2”)的相对位置信息并确定所述第二终端设备是否可作为目标终端设备。
可选的，若第一网元根据控制指示信息的指示或者预先配置的策略等方式，确定为第一终端设备确定一个或多个目标终端设备，则第一网元在根据所述多个第二终端设备的优先级，确定找到所述一个多个目标终端设备之后，可不再继续获取剩余未判断的第二终端设备的相对位置信息。
例如，UE2-1的优先级为第1优先级，UE2-2的优先级为第2优先级(所述第1优先级高于所述第2优先级)，确定选择一个目标终端设备(以下各示例中可称为“绑定UE”)。第一网元可以首先获取UE1与UE2-1的相对位置信息1，若根据所述相对位置信息1确定所述UE2-1可作为UE1的绑定UE，则无需继续获取UE1与UE2-2的相对位置信息；反之，若确定所述UE2-1不可作为UE1的绑定UE，则继续获取UE1与UE2-2的相对位置信息2，并判断UE2-2是否可作为UE1的绑定UE。
确定方式A2、所述第一网元还可以获取所述第一终端设备与所述多个第二终端设备的多个相对位置信息；然后，所述第一网元从所述多个相对位置信息中，确定满足所述控制指示信息中还包括的控制条件的至少一个相对位置信息。可以理解，在该确定方式中，第一网元可以首先共同获取所述多个位置信息，然后再从多个位置信息中选择满足控制条件的至少一个相对位置信息。
所述第一网元按照所述第二终端设备的优先级，从所述至少一个相对位置信息中确定目标相对位置信息，所述第一网元确定所述目标相对位置信息对应的第二终端设备为目标终端设备。
例如，第一网元首先共同获取UE1与UE2-1的相对位置信息1、获取UE1与UE2-2的相对位置信息2。然后，若所述第一网元可以确定相对位置信息1和相对位置信息2均满足控制条件，基于UE2-1的优先级为第1优先级，UE2-2的优先级为第2优先级(所述第1优先级高于所述第2优先级)，所述第一网元可优先选择UE2-1作为UE1的绑定UE。
示例性的，本申请实施例中可基于以下可能的场景为UE预先配置备选UE。可以理解，本申请实施例不限定于以下可能的场景。包括：
场景A1、第一终端设备和第二终端设备的位置绑定关系可为两个终端设备的相对位置信息较近时，可以达到更好的通信效果。其中，可以从与第一终端设备具有位置绑定关系的终端设备中为第一终端设备预先配置备选终端设备。
例如，第一终端设备可以为智能门锁，第二终端设备可以为用于智能解锁的终端设备(例如手机、手环等)，目标终端设备可以为处于智能门锁的可解锁范围的第二终端设备。可以理解，虽然每个第二终端设备都具有解锁能力，但通过设置第二终端设备在满足控制条件时才可进行解锁，以保障智能门锁安全性。示例性的，智能门锁在与用于智能解锁的终端设备与智能门锁相距较近时(如位于可解锁范围内)，才允许所述智能门锁可被解锁；相反，若在智能门锁的可解锁范围内未检测到预先配置的第二终端设备，则智能门锁可设置为不可解锁或者设置通过其他方式进行解锁。
这样，第一网元在对智能门锁进行通信控制时，可以基于智能门锁和用于智能解锁的终端设备的相对位置关系，确定是否存在满足控制条件的用于智能解锁的终端设备。然后实现对第一终端设备智能门锁的通信控制，从而可以提升智能门锁的解锁安全性。
场景A2、第一终端设备和第二终端设备的位置绑定关系为两个终端设备相对位置信息较近时，会产生通信干扰或安全隐患等。或者，两个终端设备的相对位置信息位置关系不近时，可以达到更好的通信效果或防止安全隐患发生。
例如，一些危险的工业设备中，这些设备附近不允许有其他设备进行工作，避免存在通信干扰。此场景下，第一终端设备可以为危险工业设备，第二终端设备可以为该工业区域内包含的普通工业设备，目标终端设备可以为所述普通工业设备中与所述危险工业设备距离较近的普通工业设备。示例性的，第一网元对危险工业设备进行通信控制时，若确定存在与所述危险工业设备距离小于安全工作范围的普通工业设备，则可控制危险工业设备停止作业或发送告警等。从而可以保障危险工业设备的工作安全。
需要说明的是，以上场景仅为本申请示出的示例，具体实现时，第一终端设备和第二终端设备的位置绑定关系还可以包括其他场景。例如，第一终端设备和第二终端设备不适合太近也不能太远的位置绑定关系等，具体实现时可根据实现场景进行设置。
本申请实施例中，第二终端设备的设备标识可表示但不限于表示为以下形式中的任一种：用户永久标识(subscription permanent identifier，SUPI)、IP地址、媒体存取控制地址(media access control address，MAC)、自定义标识。
S402b、若所述控制指示信息中包括用于指示目标区域范围的信息，所述第一网元根据所述第一终端设备与处于所述目标区域范围内的至少一个第三终端设备的相对位置信息，从所述至少一个第三终端设备中确定目标终端设备。
在一些可能的场景中，为了便于为UE选择或者重选绑定UE，还可以为UE预先配置目标区域范围。本申请实施例中，在预先配置控制指示信息时，可以为UE预先选定目标区域范围，并将用于指示所述目标区域范围的信息配置在所述控制指示信息中。例如，所述目标区域范围可以为以UE为中心且指定距离阈值为半径的圆周区域范围，此时用于指示所述目标区域范围的信息可以为圆周半径(如5米)，则第一网元解析到该区域范围标识后，可在以UE为中心且5米为半径的圆周区域范围内筛选包含的其他UE。又例如，目标区域范围还可以为UE所在的服务小区(cell)或跟踪区域(tracking area，TA)，此时用于指示所述目标区域范围的信息可以为cell标识或TA标识。需要说明的是，本申请不限定用于指示所述目标区域范围的信息形式，其他可能的形式也可以适用于本申请实施例，例如用于指示所述目标区域范围的信息还可以为多个具体位置坐标，则目标区域范围可为多个具体位置坐标所圈的区域范围等。
这样，第一网元在从控制指示信息中解析到所述目标区域范围之后，可以筛选存在于所述目标区域范围的至少一个第三终端设备，并可以从所述至少一个第三终端设备中为UE选择或者重选绑定UE。
进一步的，为了提升选择或重选绑定UE的效率、准确性，在控制指示信息中还可以预先配置第一条件，所述第一网元还可根据所述控制指示信息中还包括的第一条件，将所述目标区域范围内满足所述第一条件的终端设备作为所述第三终端设备。示例性的，所述第一条件包括但不限于以下信息中的至少一种：终端设备类型和终端设备的能力。
示例性的，在第一终端设备的目标区域范围内，只有某些类型的终端设备才会对第一终端设备的通信控制产生影响，而其他类型的终端设备不会产生影响，则无需考虑目标区域范围内全部类型的终端设备。例如，UE1可以为智能扫地机器人，目标区域范围可以为室内地图，终端设备类型可以为移动类终端设备(例如其他扫地机器人)，这样智能扫地机器人的通信控制可只考虑移动类终端设备的影响，而无需考虑固定类终端设备的影响；在此场景下，对UE1的通信控制可以为避免与其他扫地机器人相撞等。
另一示例性的，所述终端设备的能力可以为终端设备开启绑定功能、或具有移动能力、或具有语音能力等，所述预设能力可根据实际场景进行设定。例如，假设第一终端设备为语音类终端设备，在第一终端设备的目标区域范围内，只有同样具有语音能力的终端设备才会对第一终端设备产生影响，而不具有语音能力的终端设备不会对第一终端设备产生影响，则无需考虑目标区域范围内的全部终端设备，筛选所述目标区域范围内具有语音能力的终端设备作为所述第三终端设备。
本申请实施例中，针对任一第三终端设备，若所述第一网元确定所述第一终端设备与第三终端设备的相对位置信息满足所述控制指示信息中还包括的控制条件，确定所述第三终端设备为目标终端设备。因此，可以通过UE与备选UE的相对位置信息，判断备选UE是否满足绑定UE的条件，从而可以从至少一个备选UE中选择或者重选绑定UE。其中，所述控制条件可参阅S402a中介绍的内容，在此不再赘述。需要说明的是，不同第三终端设备对应相同或者不同的控制条件，具体实施时可根据实际场景进行设置。例如，相同类型的第三终端设备可以对应相同的控制条件，而不同类型的第三终端设备可以对应不同的控制条件。
此外，为了实现从至少一个第三终端设备中确定目标终端设备，第一网元也可以从所述控制指示信息中或从本地存储中或自动生成等方式，获取到预先设定参数的优先级。其中，所述预先设定参数可以包括但不限于以下参数：负载、距离。例如，若第三终端设备与其他多个终端设备绑定时，表示第三终端设备的负载较高，则可确定所述第三终端设备的优先级较低。然后基于所述预先设定参数的优先级，实现从至少一个第三终端设备中确定目标终端设备可包括以下多种确定方式，如下：
确定方式B1、所述第一网元根据预先设定参数的优先级，依次获取所述第一终端设备与所述至少一个第三终端设备(以下各实施例中可简称为“UE3”)的相对位置关系；然后，若所述第一终端设备与所述第三终端设备的相对位置信息满足所述控制指示信息中还包括的控制条件，确定所述第三终端设备为所述目标终端设备。
例如，假设预先设定参数为UE3绑定的UE数量，绑定的UE数量越多则优先级越低，绑定的UE数量越少则优先级越高。需要说明的是，若UE3绑定一个或多个UE之后，第 一网元可以更新并存储UE3与所述一个或多个UE的绑定关系。例如第一网元可以从UE3的签约信息中获取到UE3与所述一个或多个UE的绑定关系，并进一步确定UE3绑定的UE数量。以UE3-1未绑定UE，UE3-2绑定2个UE作为示例，则可以确定UE3-1的优先级高于UE3-2的优先级，第一网元可以首先获取UE1与UE3-1的相对位置信息1，若根据所述相对位置信息1确定所述UE3-1可作为UE1的绑定UE，则无需继续获取UE1与UE3-2的相对位置信息；反之，若确定所述UE3-1不可作为UE1的绑定UE，则继续获取UE1与UE3-2的相对位置信息2，并判断UE3-2是否可作为UE1的绑定UE。
确定方式B2、所述第一网元还可以获取所述第一终端设备与所述多个第三终端设备的多个相对位置信息；然后，所述第一网元从所述多个相对位置信息中，确定满足所述控制指示信息中还包括的控制条件的至少一个相对位置信息。可以理解，在该确定方式中，第一网元可以首先共同获取所述多个位置信息，然后再从多个位置信息中选择满足控制条件的至少一个相对位置信息。
所述第一网元按照预先设定参数的优先级，从所述至少一个相对位置信息中确定目标相对位置信息，所述第一网元确定所述目标相对位置信息对应的第三终端设备为目标终端设备。
例如，第一网元首先共同获取UE1与UE3-1的相对位置信息1、获取UE1与UE3-2的相对位置信息2。然后，若所述第一网元可以确定相对位置信息1和相对位置信息2均满足控制条件，基于UE3-1的优先级高于UE3-2的优先级，所述第一网元可优先选择UE3-1作为UE1的绑定UE。
示例性的，本申请实施例中可基于以下可能的场景为UE预先配置目标区域范围。可以理解，本申请实施例不限定于以下可能的场景。包括：
场景B1、第一终端设备与多个其他终端设备协同工作。
例如，图6a示出的为本申请实施例中提供的一种通信控制方法的应用场景示意图。在无人驾驶技术领域，如图6a所示的无人驾驶车队在行驶过程中，车队中包含的车辆需要与车队中的其他车辆保持安全行驶距离，且不能脱离车队。在此场景中，为了保证车间通信以及对无人驾驶车队的控制，针对无人驾驶车队中的任一无人驾驶车辆，可以预先配置所述无人驾驶车辆的控制指示信息中包含所述无人驾驶车队的目标区域范围。并且，还可以进一步预先配置所述无人驾驶车辆的控制指示信息中还包含终端设备类型为无人驾驶车辆，以及，还可以进一步预先配置所述无人驾驶车辆的控制指示信息中还包含无人驾驶车辆之间的相对距离范围。这样，第一网元可以根据控制指示信息确定出无人驾驶车队中的其他无人驾驶车辆，然后根据无人驾驶车队中的其他无人驾驶车辆实现对所述无人驾驶车辆的通信控制。
场景B2、第一终端设备避险场景或避免干扰通信场景。
例如，图6b示出的为本申请实施例中提供的一种通信控制方法的另一应用场景示意图。在无人机技术领域，若两个无人机在飞行过程中发生碰撞，则会导致严重后果，因此对无人机进行控制时，可以考虑基于目标区域范围内包含的无人机实现通信控制，从而可以避免目标区域范围内无人机相撞的风险。在此场景中，针对无人机，可以预先配置所述无人机的控制指示信息中包含以所述无人机为中心的目标区域范围。以及，还可以进一步预先配置所述无人机的控制指示信息中还包含终端设备类型为无人机。这样，第一网元可 以控制指示信息确定与无人机相距较近的其他无人机，然后根据所述其他无人机实现对所述无人机的通信控制，例如通信控制可以为避免操作控制等。
基于上述S402a和S402b介绍的内容，第一网元获取第一终端设备和备选终端设备的相对位置信息可以采用多种测量方式；其中，所述第一网元可以根据所述控制指示信息的指示或本地测量策略等方式确定采用的测量方式，本申请对此不进行限定。可以理解，在S402a中示出的实施例中，备选终端设备为第二终端设备；以及，在S402b中示出的示例中，备选终端设备为第三终端设备。示例性的，第一网元可以根据本地定位能力确定是否可以对第一终端设备和备选终端设备的相对位置信息进行测量，若无法测量可以向第三网元发送定位请求信息，例如，第一网元可以为AMF网元，第三网元可以为LMF网元；以及，第三网元也可以根据本地定位能力确定是否可以对第一终端设备和备选终端设备的相对位置信息进行测量，若无法测量可以向其他网元发送定位请求信息，例如，第一网元可以为SMF网元，第三网元可以为AMF网元，其他网元可以为LMF网元。
测量方式1，分别获取所述第一终端设备的第一位置信息和所述备选终端设备的第二位置信息，然后根据所述第一位置信息和所述第二位置信息确定所述相对位置信息。
一种可选的场景，所述第一网元可以直接向所述第一终端设备获取所述第一位置信息和向所述备选终端设备获取所述第一位置信息。另一可选的场景，所述第一网元向第三网元发送定位请求信息，所述定位请求信息用于分别获取所述第一终端设备的第一位置信息和所述备选终端设备的第二位置信息；或者，所述定位请求信息还可用于请求所述第一终端设备和所述备选终端设备的相对位置信息，而所述第三网元可以根据本地测量策略或所述定位请求信息的指示等方式采用所述测量方式1获取到所述相对位置信息，并返回给所述第一网元。
示例性的，若所述第一网元为SMF网元，所述第三网元可以为LMF网元或AMF网元；若所述第一网元为AMF网元，所述第三网元可以为LMF网元。需要说明的是，本申请对绝对位置信息的测量方式不进行限定。并且，绝对位置信息可以通过经纬度、水平高度的形式来表示，也可以其他可能的形式来表示，本申请对此不进行限定。
基于S402a中示出的实施例中，至少一个第二终端设备与第一终端设备分别对应的AMF网元可以相同也可以不同，或者部分第二终端设备对应的AMF网元与第一终端设备对应的AMF网元不完全相同。示例性的，第一网元从第一终端设备的控制指示信息中获取到至少一个第二终端设备的设备标识之后，还可以从UDM网元获取到各所述第二终端设备分别对应的AMF网元标识。本申请实施例中，第一网元可以通过各第二终端设备分别对应的AMF网元获取各第二终端设备分别测量并上报绝对位置信息，以及通过所述第一终端设备对应的AMF网元获取所述第一终端设备测量并上报绝对位置信息。
可选的，若第一网元向LMF网元发送定位请求信息，所述定位请求信息中还可以包括所述第二终端设备对应的AMF网元标识；其中，所述第二终端设备对应的AMF网元标识用于获取所述第二终端设备的第二位置信息。可以理解，LMF网元可以根据第一网元自行确定第一终端设备对应的AMF网元；例如若第一网元为AMF网元，则LMF网元可以确定所述第一网元为第一终端设备对应的AMF网元。
另一可选的，若第一网元向AMF网元发送定位请求信息，所述第一网元可以直接根据第二终端设备对应的AMF网元标识，向对应的AMF网元发送定位请求信息，此时所述 定位请求信息可用于请求UE2的绝对位置信息或UE2测量的相对位置信息。可以理解，第一网元获取UE1的绝对位置信息或UE1测量的相对位置信息时，可以向UE1对应的AMF网元发送定位请求信息；其中，第一网元可以基于UE1在核心网中的通信请求等确定UE1对应的AMF网元。可以根据第一网元自行确定第一终端设备对应的AMF网元。
例如，参阅图7a，为本申请实施例提供的获取相对位置信息的一种交互流程示意图。该交互流程可以包括：
一种可能的场景中，第一网元可以为SMF网元，第二网元可为UDM网元，此时第一网元可执行以下步骤701a。
步骤701a、SMF网元从UDM网元中获取第一终端设备(UE1)的签约信息，其中，UE1的签约信息包括至少一个第二终端设备(UE2)分别对应的AMF网元标识。可选的，所述至少一个UE2分别对应的AMF网元可以为全部UE2对应的AMF网元标识，或者也可以为与UE1的AMF网元具有不同AMF网元的UE2所对应的AMF网元标识，本申请对此不进行限定。在此场景下，UE1的签约信息中可以包括UE1的控制指示信息，所述至少一个UE2分别对应的AMF网元标识可配置于控制指示信息中、或者也可独立配置于UE1的签约消息中。可以理解，UE1的控制指示信息中还包括但不限于：多个UE2对应的设备标识、控制条件。
另一种可能的场景中，第二网元还可为AF网元，此时第一网元可执行以下步骤701b1至步骤701b2。
步骤701b1、SMF网元从AF网元获取EAP消息。其中，EAP消息中可包括UE1的控制指示信息。其中，UE1的控制指示信息中包括但不限于：多个UE2对应的设备标识、控制条件。
步骤701b2、SMF网元向UDM网元发送获取消息，所述获取消息用于请求至少一个第二终端设备(UE2)分别对应的AMF网元标识，所述获取消息包括：所述多个UE2对应的设备标识和获取服务于UE2的AMF信息的指示。示例性的，UDM网元接收到所述获取消息之后，根据所述获取消息中包含的所述多个UE2对应的设备标识和获取服务于UE2的AMF信息的指示，确定至少一个UE2分别对应的AMF网元标识，并返回给所述SMF网元。
与步骤701a不同之处在于，在此场景下，SMF网元可从不同网元获取UE2的控制指示信息和至少一个UE2分别对应的AMF网元标识。这样，核心网的网元可以实现基于UE1所在核心网络和第三方服务网络共同实现对UE1的通信控制。
步骤702、SMF网元请求UE1对应的AMF网元1确定目标终端设备(绑定UE)。示例性的，在UE1请求SMF网元建立会话等场景下，SMF网元可将从UDM网元、或从AF网元和UDM网元获取到的控制指示信息和至少一个UE2分别对应的AMF网元标识等信息，转发给UE1对应的AMF网元1。AMF网元1接收到来自SMF网元的用于确定绑定UE的请求之后，可以获取UE1与UE2的相对位置信息，以及还可以基于UE1与UE2的相对位置信息，从多个UE2中确定绑定UE。
步骤703、AMF网元1可以请求LMF网元协助确定目标终端设备。一种可能的场景中，AMF网元1接收到来自SMF网元的用于确定绑定UE的请求之后，可以根据定位能力判断是否可以测量UE1和UE2的相对位置信息；如果AMF网元1没有获取UE1或UE2位置的定位能力、或AMF网元1的定位能力不能满足UE1和UE2的定位需求(比如定位 精度无法满足，指示的测量方式不支持等)，则AMF网元1可向LMF网元发送定位请求信息。其中，所述定位请求信息可以包括：UE1的设备标识、UE2的设备标识、所述至少一个UE2分别对应的AMF网元标识以及指示信息，所述指示信息用于请求LMF网元获取UE1与UE2的相对位置信息。
另一可选的，SMF网元也可直接向LMF网元请求协助确定目标终端设备。示例性的，所述SMF网元可向LMF网元发送定位请求信息。其中，所述定位请求信息可以包括：UE1的设备标识、UE2的设备标识、所述至少一个UE2分别对应的AMF网元标识以及指示信息，所述指示信息用于请求LMF网元获取UE1与UE2的相对位置信息。
另外，在一些可能的场景中，例如核心网中未部署LMF网元等，第一网元还可以通过AMF网元实现协助确定目标终端设备。例如，若第一网元为SMF网元，则SMF网元可请求AMF网元协助确定目标终端设备。又例如，若第一网元为AMF网元，则AMF网元可由本地确定目标终端设备。
基于上述各种示例，通常可以基于第一终端设备与第二终端设备的相对位置信息，确定第二终端设备是否可作为目标终端设备。鉴于此，LMF网元或AMF网元可协助确定第一终端设备与第二终端设备的相对位置信息。
步骤704a、LMF网元从UE1对应的AMF网元1获取UE1的绝对位置信息。

从步骤704a，以及步骤704b可以得到，LMF网元可分别通过UE1和UE2分别对应的不同AMF网元，实现对UE1的绝对位置信息和UE2的绝对位置信息的测量。然后，LMF网元可基于UE1的绝对位置信息和UE2的绝对位置信息，计算得到UE1与UE2的相对位置信息，以及基于相对位置信息确定UE2是否可作为目标终端设备，然后将确定的目标终端设备返回给第一网元。或者LMF网元可基于UE1的绝对位置信息和UE2的绝对位置信息，计算得到UE1与UE2的相对位置信息，然后将相对位置信息返回给第一网元，由第一网元根据相对位置信息确定目标终端设备。或者LMF还可直接将UE1的绝对位置信息和UE2的绝对位置信息返回给第一网元，由第一网元对UE1和UE2的相对位置信息进行计算，并确定目标终端设备。本申请对具体实现方式不进行限定。
基于S402b中示出的实施例中，至少一个第三终端设备与第一终端设备处于相同的目标区域范围，因此通常对应相同的AMF网元。此时，第一网元可直接请求UE1对应的AMF网元或LMF网元协助确定目标终端设备，具体确定方式可参阅图7a示出的交互流程，在此不再赘述。
测量方式2，获取所述第一终端设备测量的相对位置信息、或所述备选终端设备测量的相对位置信息。其中，所述第一网元可以直接向所述第一终端设备请求测量相对位置信息；或者还可以直接向所述备选终端设备请求测量相对位置信息。或者，所述第一网元还可向第三网元发送定位请求信息，所述定位请求信息用于请求所述第一终端设备测量的相对位置信息、或所述备选终端设备测量的相对位置信息。又或者，所述第一网元向第三网元发送定位请求信息，所述定位请求信息用于请求所述第一终端设备和所述备选终端设备的相对位置信息，而所述第三网元采用所述测量方式2获取到所述相对位置信息，并返回给所述第一网元。

基于S402a中示出的实施例中，至少一个第二终端设备与第一终端设备分别对应的AMF网元可以相同也可以不同，或者部分第二终端设备对应的AMF网元与第一终端设备对应的AMF网元不完全相同。示例性的，第一网元从第一终端设备的控制指示信息中获取到至少一个第二终端设备的设备标识之后，还可以从UDM网元获取到各所述第二终端设备分别对应的AMF网元标识。可选的，第一网元可以通过各所述第二终端设备分别对应的AMF网元，指示各所述第二终端设备分别测量并上报与所述第一终端设备的相对位置信息。另一可选的，若第一网元向第三网元发送定位请求信息，所述定位请求信息中还可以包括所述第二终端设备对应的AMF网元标识；其中，所述第二终端设备对应的AMF网元标识用于请求所述第二终端设备测量相对位置信息。可以理解，第三网元可以根据第一网元自行确定第一终端设备对应的AMF网元。
例如，参阅图7b，为本申请实施例提供的获取相对位置信息的另一种交互流程示意图。
其中，步骤701a至步骤703可参阅图7a对应的实施例内容，在此不再赘述。
步骤704c、LMF网元从UE2对应的AMF网元2获取UE2测量的与UE1的相对位置信息。

其中，LMF网元可根据控制指示信息中的指示或者本地测量策略等信息，选择图7a示出的测量方式1或者选择图7b示出的测量方式2进行定位测量。并且，若选择图7b示出的测量方式2进行定位测量，还可以根据控制指示信息中的指示或者本地测量策略等信息，选择步骤704c所对应的实现方式、或选择步骤704d所对应的实现方式进行定位测量。
此外，在一些可能的场景中，例如核心网中未部署LMF网元等，第一网元还可以通过AMF网元实现协助确定目标终端设备。例如，若第一网元为SMF网元，则SMF网元可请求AMF网元协助确定目标终端设备。又例如，若第一网元为AMF网元，则AMF网元可由本地确定目标终端设备。示例性的，所述第一网元通过所述UE1对应的AMF网元1，指示所述UE1分别测量与各所述UE2的相对位置信息；以及，所述第一网元通过各所述UE2对应的AMF网元2，指示各所述UE2测量与所述UE1的相对位置信息。
基于S402b中示出的实施例中，至少一个第三终端设备与第一终端设备处于相同的目标区域范围，因此通常对应相同的AMF网元。此时，第一网元可直接向UE1对应的AMF网元或LMF网元请求所述相对位置信息。
基于上述实现方式，以下结合图8a至图8c介绍终端设备测量与其他终端设备的相对位置信息的几种可能的测量方式。
示例性的，以第一终端设备测量相对位置信息作为示例，图8a为本申请实施例示出的测量相对位置信息的场景示意图，此时所述相对位置信息可表示为相对距离。第一终端设备可以接收核心网的网元(如LMF网元或AMF网元或SMF网元)的定位请求信息，启动测量相对位置信息的流程。实施时，第一终端设备可向第二终端设备(或第三终端设备)发送测距信号，第二终端设备(或第三终端设备)接收到测距信号之后，可以对该测距信号立即进行反馈。这样，第一终端设备可基于信号的飞行时间(time of flight，TOF)来测量得到第一终端设备和所述第二终端设备(或第三终端设备)的相对距离。例如，图8b 为本申请实施例示出的测量相对距离的另一场景示意图，TOF＝Tprop＝(Tround-Treply)/2；然后，根据所述TOF与光速的乘积可以得到相对距离。
另一示例性的，仍以第一终端设备测量相对位置信息作为示例，图8c为本申请实施例示出的测量相对位置信息的又一场景示意图。此时所述相对位置信息可表示为相对方向。第一终端设备包括的接收器可通过天线接收到来自第二终端设备(或第三终端设备)包括的发射器发送的信号，并可测量得到该信号相对参考方向的到达角，从而可以基于所述相对参考方向的到达角得到第二终端设备(或第三终端设备)与所述第一终端设备的相对方向。
需要说明的是，第一终端设备或第二终端设备(或第三终端设备)也可以通过其他测量方式来测量得到所述相对位置信息，例如，还可以通过物物直连技术(比如sidelink)，超宽带(ultra wide band，UWB)等方式测量所述相对位置信息，本申请对此不进行限定。
又一示例性的，若第一网元向LMF网元发送定位请求信息，所述LMF网元可以通过但不限于以下定位方式获取相对位置信息：到达时间观测时间差(observed time difference of arrival，OTDOA)、辅助全球导航卫星系统(assisted-global navigation satellite system，A-GNSS)、上行到达时间差(uplink time difference of arrival，UTDOA)。

示例性的，所述第一网元可以向第三网元发送订阅指示，所述订阅指示可以包括但不限于以下信息中的一种或组合：控制指示信息中包含的控制条件，UE的设备标识、绑定UE的设备标识、监测频率(或监测条件)、重选指示。其中，第三网元可以根据所述监测频率，周期性测量UE和绑定UE的相对位置信息；或者所述第三网元也可以根据监测条件测量UE和绑定UE的相对位置信息，例如监测条件可以为在监测到UE或绑定UE的cell或TA进行了切换时，触发重新测量UE和绑定UE的相对位置信息。所述重选指示用于指示若第一终端设备和目标终端设备的相对位置信息不再满足控制指示信息中的控制条件，是否需要重选目标终端设备。
以及，若所述第一网元确定不再存在满足所述控制条件的目标终端设备，或者若目标终端设备不再满足控制条件时且不再重选目标终端设备，则所述第一网元可以根据所述控制指示信息中还包括的处理指示对所述第一终端设备的通信进行处理；或者还可以根据从PCF网元中获取的策略控制消息指示的处理方式对所述第一终端设备的通信进行处理。可以理解，如果第一网元已经基于为UE确定的绑定UE为UE建立通信(例如建立会话或接入切片)，若第一网元确定不再存在绑定UE，则可以对UE已经建立的通信进行处理。
另一可选的，若绑定UE关闭绑定功能之后，也可以触发是否重选目标终端设备；例 如若第三网元或第一网元监测到绑定UE关闭绑定功能，则可以根据本地存储策略或控制指示信息中的指示，确定是否重选目标终端设备。示例性的，若绑定UE向AMF网元发送会话释放请求，所述AMF网元根据会话释放请求确定绑定UE释放了用于开启绑定功能的PDU session type消息，则可以确定绑定UE关闭绑定UE；另一示例性的，若SMF网元监测到绑定UE的会话释放成功，也可以由SMF网元指示AMF网元启动重新绑定UE的流程。此外，若不需要重选目标终端设备或者未重现到新的目标终端设备；其中，AMF网元可以接收SMF网元发送的绑定UE的PDU session type消息。第一网元也可以对基于绑定UE为UE建立的通信进行处理；例如，如果绑定UE通过PDU会话开启绑定功能，在绑定UE释放用于开启绑定功能的PDU会话之后，表示绑定UE关闭绑定功能。

另外，本申请实施例中，无论第二终端设备(或第三终端设备)是否被确定为目标终端设备，第一网元获取所述相对位置信息之后，根据实际场景需求，也可以订阅所述第一终端设备与所述第二终端设备(或第三终端设备)的相对位置信息。这样，第一网元可以根据所述第一终端设备与所述第二终端设备(或第三终端设备)更新的相对位置信息，及时地重新目标终端设备。例如，若第一网元订阅到存在优先级更高的第二终端设备，变更为可以作为目标终端设备，则所述第一网元可以触发或者请求重选目标终端设备，也即将所述优先级更高的第二终端设备重选为目标终端设备；然后第一网元可以根据重选的目标终端设备，对第一终端设备进行通信控制。
上述实施例中，第一网元可以向AMF网元或LMF网元订阅所述相对位置信息。

步骤900、SMF网元对备选UE进行服务控制。本申请实施例中，核心网设备除了可以基于相对位置信息对UE进行通信控制，根据实际场景的需求，还可以实现基于绝对位置信息对UE的通信控制。例如，UE通常可以实现多种类型的业务处理，第一类型的业务处理是处于UE1和备选UE具有位置绑定关系的场景下，则核心网设备可对UE1对第一类型的通信请求进行基于相对位置信息的通信控制；而第二类型的业务处理是备选UE本 地实现业务处理，不与其他UE存在位置绑定关系。因此，核心网设备对UE1进行通信控制的场景下，也可实现对备选UE和UE1基于绝对位置进行通信控制。示例性的，在备选UE请求建立会话的场景下，核心网设备对备选UE的通信控制可以为服务控制。
(二)确定目标终端设备阶段

另一示例性的，AMF网元接收到所述定位请求信息，也可以根据所述定位请求信息的指示确定采用的测量方式；或者若所述定位请求信息未指示采用的测量方式，AMF网元可以基于本地测量策略选择采用的测量方式。可选的，AMF网元可采用前述实施例中介绍的直接测量方式或者间接测量方式；或者AMF网元还可以继续向LMF网元转发所述定位请求信息，所述LMF接收到定位请求信息之后的处理流程可参阅前述示例内容。此外，若所述定位请求信息中还指示备选UE的AMF网元标识，AMF网元还可根据备选UE的AMF网元标识，若AMF网元采用间接测量方式，可向备选UE的AMF网元请求备选UE的第二位置信息；或者，若采用直接测量方式，也可向备选UE的AMF网元请求备选UE测量的相对位置信息。或者，所述SMF网元也可以直接根据控制指示信息中指示的备选UE对应的AMF网元标识，向备选UE对应的AMF网元发送定位请求信息，用于请求备选UE 的绝对位置信息或者备选UE测量的相对位置信息。
场景a3、SMF网元直接向AMF网元或LMF网元发送定位请求信息，所述定位请求信息还可用于指示确定目标终端设备。可以理解，此时SMF网元可请求AMF网元或LMF网元协助确定目标终端设备；然后SMF网元可直接从AMF网元或LMF网元获取到所述目标终端设备。
在此场景下，AMF网元或LMF网元除了获取相对位置信息，还可实现对目标终端设备的判断，然后直接向确定的目标终端设备返回给SMF网元。SMF网元可直接基于目标终端设备，对第一终端设备进行通信控制。
