一种业务管理方法及装置
相关申请的交叉引用
本申请要求在2019年12月31日提交中国国家知识产权局、申请号为201911417014.2、申请名称为“一种业务管理方法及装置”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
本申请涉及定位技术领域，尤其涉及一种业务管理方法及装置。
背景技术
移动网络提供位置业务(location services，LCS)，定位需求方(也称为LCS client)可以向网络请求获得需要定位的终端设备的位置。例如，用户拨打110电话，网络定位用户使用的终端设备的位置，并将该位置发送给公安局。
新无线(new radio)网络提供的一些业务和位置区域有关系，例如体育赛事的直播可能只在特定的体育馆，一旦终端设备离开了该体育馆，那么终端设备无法播放体育赛事。而目前网络定位的最小粒度是小区，也就是网络只能定位终端设备处于哪个小区，而无法定位到粒度比小区更小的位置区域。这样即使终端设备脱离与业务对应的位置区域，仍然可以继续进行业务，例如没有购票的用户在体育馆外仍然可以通过终端设备观看体育赛事，造成商家的损失。
如何实现更小粒度地定位终端设备，以确定是否允许终端设备继续当前业务，目前尚无解决的方案。
发明内容
本申请提供一种业务管理方法及装置，用于根据终端设备的精确定位，管理终端设备的业务，满足提供业务服务的第三方的实际需求。
第一方面，本申请实施例提供一种业务管理方法，该方法的执行主体可以是会话管理网元，例如为会话管理功能(session management function，SMF)网元，也可以是应用于SMF网元中的芯片。下面以执行主体是SMF为例进行描述。该方法包括：SMF根据来自第一网元的第一消息，获知第一业务以及第一位置信息，以及确定终端设备不在所述第一位置区域，则确定终止所述第一业务或者通知所述第二网元所述终端不在所述第一位置区域，其中，所述第一位置信息用于指示所述第一业务允许的第一位置区域，所述第二网元用于提供所述第一业务。
本申请实施例中，SMF可以根据第一网元发送的第一消息，确定终端设备将要进行或已经进行的第一业务，以及该第一业务允许的第一位置区域，该第一位置区域可以为特定区域，例如体育馆。从而SMF在确定终端设备不在该第一位置区域时，可以终止第一业务；或者SMF告知提供第一业务的第二网元，由第二网元确定是否终止第一业务。应理解，SMF终止第一业务，可以包括SMF接收来自终端设备会话请求消息，该会话请求消 息用于请求第一业务，SMF拒绝建立与终端设备的会话。SMF终止第一业务也可以包括SMF已经与终端设备建立了会话连接，SMF通知终端设备断开与SMF的会话连接。通过该方法，可以确定终端设备比小区更细粒度的位置信息，并根据定位的位置信息管理终端设备进行的业务，例如在终端设备位于与业务关联的特定区域之外时，断开终端设备进行的业务，可以避免购买该业务权限的商家的损失。
在一种可能的设计中，所述SMF确定终端设备不在所述第一位置区域包括但不限于以下两种方式：
示例性的，所述SMF确定终端设备不在所述第一位置区域，包括：
所述SMF向位置管理网元发送第二消息，所述第二消息包括所述第一位置信息；
所述SMF接收来自所述位置管理网元的第三消息，根据第三消息确定所述终端设备不在所述第一位置区域，其中，所述第三消息用于指示所述终端设备不在所述第一位置区域。
SMF可以通过具有定位终端设备的位置的功能位置管理网元，例如位置管理功能(location management function，LMF)需要确定终端设备在不在第一位置区域时。下文以位置管理网元是LMF为例，SMF可以将第一位置区域告知LMF，例如SMF向LMF发送指示第一位置区域的第二消息，从而LMF确定了终端设备当前的位置之后，可以比较终端设备当前的位置和第一位置区域，当终端设备不在第一位置区域，那么LMF可以告知SMF。通过该方案，由LMF确定终端设备在不在第一位置区域，可以减轻SMF的负担。
在一种可能的设计中，所述第二消息用于订阅第一事件，所述第一事件为所述终端设备离开所述第一位置区域时，通知所述SMF的事件。
该方案中，SMF可以向LMF请求多次上报终端设备的位置，例如可以实现定义终端设备离开第一位置区域时，通知SMF的事件，SMF可以向LMF发送订阅该事件的消息，这样LMF一旦确定终端设备不在第一位置区域就向SMF上报。采用该方案，不需要SMF向LMF多次发送第二消息，节省了SMF的信令开销。
示例性的，所述SMF确定终端设备不在所述第一位置区域，包括：
所述SMF接收来自LMF的第四消息，所述第四消息包括第二位置信息，所述第二位置信息用于指示所述终端设备当前所在的位置；
若所述第二位置信息指示的位置不在所述第一位置区域内，则所述SMF确定所述终端设备不在所述第一位置区域。
与上述示例性的方案不同之处在于，在本方案中，SMF自己确定终端设备当前是否位于第一位置区域。例如SMF可以向LMF请求获取终端设备当前的位置，通过比较终端设备当前的位置和第一位置区域，可以确定终端设备是否位于第一位置区域。
在一种可能的设计中，所述方法还包括：
所述SMF向所述LMF发送第二消息，其中，所述第二消息用于请求获取所述终端设备当前所在的位置，或者所述第二消息用于订阅终端设备位置的事件，指示所述LMF定期上报所述终端设备当前的位置。
在该方案中，SMF可以向LMF请求单次上报终端设备当前的位置，也可以向LMF请求定期上报终端设备当前的位置，例如第二消息为用于订阅终端设备位置的事件的消息，以尽量节省SMF的信令开销。
在一种可能的设计中，所述第二消息包括定位精度，所述定位精度是根据所述第一位 置区域确定的。
在该方案中，第二消息可以包括定位精度，而该定位精度可以根据第一位置区域确定，例如第一位置区域覆盖的范围较大，那么定位精度较低，也就是例如以终端设备为中心的距离可以较长；相反如果第一位置区域覆盖的范围较小，那么定位精度较高，以更加准确地确定终端设备是否位于第一位置区域。
在一种可能的设计中，所述SMF向所述LMF发送第二消息，包括：
所述SMF获取所述终端设备当前的位置信息；
所述SMF根据所述位置信息无法确定所述终端设备是否位于所述第一位置区域，则向所述LMF发送所述第二消息。
该方案提供了SMF向LMF请求获取终端设备当前的位置的时机。通常来说终端设备如果进行某个业务，那么终端设备与SMF会建立会话，SMF会存储与该终端设备相关的会话信息，包括终端设备当前的位置信息。目前该位置信息是以小区粒度为单位的，例如该位置信息可以指示终端设备位于哪个小区。如果第一位置区域覆盖范围小于小区，那么SMF无法确定终端设备当前是否位于第一位置区域。此时SMF可以向LMF发送第二消息，以请求LMF对终端设备进行较高精度的定位。
在一种可能的设计中，所述方法还包括：
所述SMF向所述终端设备发送第五消息，所述第五消息用于请求终止所述第一业务；或者，所述SMF向第二网元发送第六消息，所述第六消息用于指示通知所述第二网元终止所述第一业务，其中，所述第二网元用于提供所述第一业务；或者，
所述会话管理网元接收来自所述终端设备的第七消息，所述第七消息用于请求建立第一业务的会话，所述会话管理网元拒绝建立所述第一业务的会话。
该方案提供了SMF确定终端设备不在第一位置区域的后续三种处理流程，其中的一种是针对SMF与终端设备已经建立了会话，SMF确定终止第一业务，可以较为及时地终止第一业务，尽量避免造成购买第一业务权限的商家的损失。另一种也是针对SMF与终端设备已经建立了会话，SMF可以告知第二网元，例如为应用功能(application function，AF)，终端设备不在第一位置区域，由AF确实是否终止第一业务，更为合理。例如，进行第一业务的终端设备可能是会员，具有在第一位置区域之外进行第一业务的权限，那么AF可以不终止第一业务，更为合理。再一种是终端设备还没与SMF建立会话连接，如果之后SMF接收到终端设备的请求第一业务的会话连接请求，SMF可以拒绝建立第一业务的会话。
在一种可能的设计中，所述第一网元为网关移动位置网元，例如为网关移动位置中心(gateway mobile location centre，GMLC)，或者所述第一网元为用户面网元，例如为用户数据管理(unified data management，UDM)或策略控制功能(policy control function，PCF)。下文中以网关移动位置网元是GMLC为例，以用户面网元是UDM或PCF为例。
在不同的应用场景中，第一网元可以有不同的具体实现，例如如果终端设备与SMF已经建立了会话，那么应用网元，例如AF可以知道是哪个终端设备进行第一业务，直接告诉GMLC，应理解，GMLC是第一网元；如果终端设备与SMF还没有建立会话，那么AF并不知道是那个终端设备进行第一业务，SMF可以从UDM或PCF查找与第一业务对应的第一位置区域，应理解UDM或PCF是第一网元。
在一种可能的设计中，SMF根据来自第一网元的第一消息，获知第一业务，包括：
所述SMF根据来自所述GMLC的第一消息获知所述第一业务，所述第一消息包括用于指示所述第一业务的业务标识信息，所述业务标识信息包括所述终端设备的身份标识信息；或者，所述SMF根据来自所述UDM或PCF的第一消息获知所述第一业务，所述第一消息包括用于指示所述第一业务的业务标识信息，所述业务标识信息包括数据网络网元，例如数据网络网元名称(data network name，DNN)。
在不同的应用场景中，SMF获知第一业务也有所不同。例如如果终端设备与SMF已经建立了会话，那么AF可以知道是哪个终端设备进行第一业务，直接告诉GMLC，GMLC向SMF发送的第一消息可以携带例如终端设备的身份标识信息，用来指示第一业务；又例如如果终端设备与SMF还没有建立会话，那么SMF可以从UDM或PCF查找终端设备要进行的第一业务。
在一种可能的设计中，所述第一位置信息包括如下任意一种：
小区标识列表；或者，跟踪区列表；或者，位置坐标；或者，位置坐标和位置偏差值。
在该方案中，第一位置信息有多种实现方式，例如第一位置信息可以是小区标识列表，跟踪区列表、位置坐标，或者位置坐标和位置偏差值，较为灵活。
第二方面，提供了一种业务管理方法，该方法的执行主体可以是网关移动位置网元，例如为网关移动位置中心(gateway mobile location centre，GMLC)，也可以是应用于GMLC网元中的芯片。下面以执行主体是GMLC为例进行描述。该方法包括：
GMLC接收来自应用网元的第一消息，所述第一消息包括第一标识信息和第一位置信息，其中，所述第一标识信息用于指示第一业务，所述第一位置信息用于指示所述第一业务允许的第一位置区域；
所述GMLC向第一网元发送第二消息，所述第二消息包括所述第一标识信息和所述第一位置信息。
在一种可能的设计中，所述第一网元为SMF、UDM或者PCF。
在本申请实施例中，应用网元，例如AF作为提供第一业务服务的网元，可以将第一业务以及该第一业务允许的第一位置区域告知GLMC。例如终端设备与SMF已经建立了会话，GLMC可以将第一业务以及第一位置区域告知第一网元，例如SMF。或者例如终端设备还未与SMF建立会话，GMLC可以将第一业务以及第一位置区域告知UDM或PCF，从而SMF可以从UDM或PCF获知第一业务以及第一位置区域。采用该方案，SMF可以根据进行第一业务的终端设备当前位置是否在第一位置区域，而确定是否终止第一业务，或者告知AF，终端设备当前位置不在第一位置区域，由AF确定是否终止第一业务网。可见采用该方案，可以根据终端设备的位置来管理终端设备进行的业务，以尽量避免为购买业务权限的商家造成损失。
第三方面，提供了一种业务管理方法，该方法的执行主体可以是位置管理网元，例如LMF网元，也可以是应用于LMF网元中的芯片。下面以执行主体是LMF网元为例进行描述。LMF接收来自SMF的第一消息，所述第一消息用于订阅第一事件，所述第一事件为所述终端设备当前不在第一位置区域时通知所述SMF的事件；
所述LMF响应所述第一消息，向所述SMF发送第二消息，所述第二消息用于指示终端设备当前不在所述第一位置区域。
在一种可能的设计中，所述方法还包括：
所述LMF周期性地确定所述终端设备当前所在的位置。
在该方案中，第一消息可以是用于订阅终端设备当前不在第一位置区域时通知SMF的事件的消息，LMF作为具有定位终端设备位置功能的网元，可以确定终端设备是否位于第一位置区域，一旦终端设备离开第一位置区域，那么LMF可以上报给SMF。采用该方案，SMF只需要发送一次第一消息，就可以指示LMF多次上报终端设备的位置，节省SMF的信令开销。
第四方面，提供了一种通信装置，例如该通信装置为如前所述的接入管理网元，例如SMF。该通信装置具有实现上述第一方面方法实施例中的行为的功能。所述功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。所述硬件或软件包括一个或多个与上述功能相对应的模块。在一个可能的设计中，所述通信装置例如包括相互耦合的处理模块和收发模块，其中，所述处理模块，用于根据所述收发模块接收的来自第一网元的第一消息，获知第一业务以及第一位置信息，所述第一位置信息用于指示所述第一业务允许的第一位置区域；以及确定终端设备不在所述第一位置区域，则确定终止所述第一业务或者通知所述第二网元所述终端不在所述第一位置区域，所述第二网元用于提供所述第一业务。这些模块可以执行上述第一方面方法示例中的相应功能，具体参见方法示例中的详细描述，此处事不再赘述。

定位相关的网元，例如包括网络开放功能(network exposure function，NEF)网元、网关移动位置网元，例如GMLC、位置管理网元，例如LMF、位置存储功能(Location Retrieval Function，LRF)和计费功能(charging function，CHF)。在本文中，以网关移动位置网元，是GMLC，位置管理网元是LMF为例。
本申请实施例中，GMLC负责从LCS客户端(client)接收定位请求，并将定位结果发送给LCS client。在5G中，在未来通信如第六代(the 6th generation，6G)中，网关移动位置网元仍可以是GMLC网元，或有其它的名称，本申请实施例不做限定。

例如在一种可能的应用场景中，第三方服务为终端设备提供的业务是与位置区域关联的。例如体育赛事的转播，例如VR视频，只针对特定区域(例如体育馆)，一旦终端设备离开该体育馆，那终端设备就无法继续体育赛事的转播。目前网络对于用户业务结合用户(终端设备)位置的管理，只能定位到终端设备位于哪个小区，而无法感知比小区更细粒度的位置，即使终端设备脱离体育馆，但是还位于包括体育馆的小区，终端设备仍然可以继续体育赛事的转播，例如没有购票的用户在体育馆外仍然可以通过终端设备观看体育赛 事，造成商家的损失。为此，本申请实施例可以确定终端设备具体位于小区中的某个位置区域，以确定是否允许终端设备将要进行或已经进行的业务，增强网络的控制，避免购买网络业务的商家的损失。
为解决上述技术问题，基于图2所示的架构。如图3所示，本申请实施例提供一种业务管理方法。该方法可以确定UE比小区更细粒度的位置信息，并根据定位的位置信息管理UE进行的业务，例如在UE位于与业务关联的特定区域之外时，断开UE进行的业务，以避免造成商家的损失。
本申请实施例的技术方案可以应用于各种通信系统，例如：NR系统、5G系统以及下一代移动通信系统等，只要是该通信系统提供LCS均可。
此外，所述通信系统还可以适用于面向未来的通信技术，本申请实施例描述的系统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，随着网络架构的演变，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。
下面基于图2所示的架构对本申请实施例提供的业务管理方法进行具体描述。
请参考图3，为本申请提供的业务管理方法流程示意图。该方法的具体流程描述如下：
S301、第一网元向SMF发送第一消息，SMF接收该第一消息，该第一消息可以指示第一业务和第一业务允许的第一位置区域。
S302、SMF确定终端设备不在第一位置区域，则确定终止第一业务。
本申请实施例旨在确定将要进行的第一业务或者已经进行的第一业务的终端设备是否位于第一业务允许的第一位置区域，如果确定终端设备位于第一位置区域，那么第一业务正常进行；相反，如果确定终端设备不在第一位置区域，那么可以确定终止第一业务以尽量避免对提供第一业务的商家造成损失。
需要说明的是，SMF终止第一业务，根据SMF是否与终端设备建立会话连接而有所不同。如果SMF与终端设备已经建立第一业务的会话连接，SMF终止第一业务可以包括SMF通知终端设备断开与SMF的第一业务的会话连接。如果SMF还未与终端设备已经建立第一业务的会话连接，SMF终止第一业务可以包括SMF接收来自终端设备用于请求建立第一业务的会话的消息，SMF拒绝建立与终端设备的会话。
在一些实施例中，作为S302的一种可替换的方法，S303、SMF确定终端设备不在第一位置区域，则通知第二网元该终端设备不在第一位置区域，该第二网元可以是提供第一业务的网元。也就是SMF确定终端设备不在第一位置区域，可以通知给提供第一业务的第二网元。这样由第二网元确定是否需要终止第一业务，可以较为合理地终止第一业务。需要说明的是，S302和S303不是都必须执行，因此，图3以虚线示意S303。
终端设备要进行某个业务，例如第一业务时，可以请求与SMF建立会话，以请求接入第一业务。当终端设备和SMF建立了会话，SMF可以为该会话分配用于标识终端设备请求的第一业务的信息，例如可以是终端设备的网际协议(internet protocol，IP)地址。在下文中，用于标识终端设备请求的第一业务的信息也称为业务标识信息，应理解，该业务标识信息可以是终端设备的IP地址。在一些实施例中，业务标识信息也可以是终端设备的IP地址、订阅永久标识符(subscription permanent identifier，SUPI)或者通用公共订阅标识符(generic public subscription identifier，GPSI)等。
终端设备与SMF建立了会话之后，提供第一业务的网元，也就是第二网元，例如AF 可以和终端设备的应用层进行通信，从而可以获知是哪个终端设备请求第一业务，以及该终端设备请求的第一业务。考虑到第一业务可能只有在特定的区域，例如第一位置区域才可以进行，如果终端设备不在第一位置区域时，可以确定终止第一业务或者，可以告知AF，终端设备不在第一位置区域。在下文中，以第二网元是AF为例。
为此SMF需要确定终端设备是否在第一位置区域，在不同的应用场景中，SMF确定终端设备是否在第一位置区域的流程也有所不同。下面分别以不同应用场景为例，介绍本申请实施例提供的方案。
在第一种应用场景中，以终端设备与SMF建立了会话为例。
由于终端设备与SMF建立了会话，所以AF可以获知终端设备请求的第一业务，以及请求第一业务的终端设备是哪个终端设备。之后，AF可以向GMLC发送配置请求消息，该配置请求消息可以包括用于标识AF的信息和用于标识终端设备请求的业务的信息。AF可以提供第一业务，同时AF也知道第一业务允许的第一位置区域，所以上述配置请求消息还可以包括用于标识终端设备请求的第一业务允许的位置的信息。为了便于描述，下文中，将用于标识AF的信息称为第一信息，将用于标识第一业务允许的位置的信息称为第一位置信息。
其中，第一信息可以是AF的身份标识(Identity，ID)。第一业务允许的第一位置区域的粒度可能较大，也可能较小。例如第一位置区域的粒度可以是小区，即第一位置区域对应小区，第一位置区域的粒度可以小于小区，即第一位置区域对应小于小区的区域，例如第一位置区域是小于小区的体育馆。在一些实施例中，如果第一业务允许的位置区域是小区区域，第一位置信息可以包括小区标识(cell ID)列表(list)，或者如果第一业务允许的位置区域是大于小区的位置区域，第一位置信息可以包括跟踪区列表(tracking area，TA list)。如果第一业务允许的位置区域是小于小区的位置区域，第一位置信息可以指示位置坐标，例如第一位置信息包括全球定位系统(global positioning system，GPS)坐标。在另一些实施例中，第一位置信息也可以包括位置坐标和位置偏差值，这种情况下，第一位置信息指示的位置区域为以位置坐标为中心，以位置偏差值为半径的一个圆形区域。应理解，如果第一业务允许的位置区域是小区区域，位置坐标小区的中心坐标，位置偏差值为小区的半径。如果第一业务允许的位置区域是大于小区的位置区域，位置坐标小区的中心坐标，位置偏差值大于小区的半径。如果第一业务允许的位置区域是小于小区的位置区域，位置坐标小区的中心坐标，位置偏差值小于小区的半径。
GMLC接收来自AF的配置请求消息之后，可以根据接收的配置请求消息包括的AF ID对AF进行鉴权和授权。GMLC在对AF鉴权通过后，可以根据配置请求消息包括的终端设备的标识，确定为终端设备服务的SMF。之后，GMLC可以向该SMF发送第一消息，该第一消息可以包括第一位置信息和业务标识信息，例如上述的终端设备的IP地址。应理解，SMF可以根据来自GMLC的第一消息获知第一业务，例如第一消息包括终端设备的IP地址。在一些实施例中，该第一消息也可以称为业务更新请求消息。应理解，在这种场景下，GMLC为第一网元。SMF根据该第一消息可以获知终端设备进行的第一业务，以及该第一业务允许的第一位置区域。从而SMF可以根据终端设备当前所在的位置是否在第一位置区域，而确定是否终止第一业务，或者SMF告知AF，终端设备不在第一位置区域。
在第二种应用场景中，以终端设备当前没有与SMF建立会话为例。
终端设备当前可能并没有与SMF建立会话，也就是终端设备当前没有请求第一业务。 与上述第一种应用场景相同，在第二种场景中，AF向GMLC发送的配置请求消息同样可以包括AF ID、业务标识信息和位置信息。与上述第一种应用场景中的不同之处在于，其中的业务标识信息可以用于指示具体的某个业务，例如第二业务。但是该第二业务不限定某个终端设备，也就是说，该配置请求消息针对的是业务，但是不限定某个终端设备。在可能的实施方式中，该业务标识信息可以包括数据网络名称(data network name，DNN)，也可以包括服务标识(service ID)，或者可以包括IP五元组。应理解，该位置信息，例如第二位置信息指示的位置区域为该业务标识信息指示的业务(即第二业务)允许的位置区域。其中第二位置信息具体实现与上述第一种应用场景中的第一位置信息的具体实现类似，这里不再赘述。
与上述第一种应用场景中的不同之处在于，终端设备还没有与SMF建立会话，GMLC无法确定为终端设备服务的SMF。这种情况下，GMLC可以将第二业务以及第二业务允许的第二位置信息告知UDM或PCF。例如GMLC可以向UDM或PCF发送第一消息，该第一消息包括业务标识信息和第二位置信息，例如UDM或PCF可以保存业务标识信息指示的第二业务与第二位置信息指示的位置区域的对应关系。应理解，UDM或PCF可以存储多个业务中的每个业务与位置区域的对应关系，其中一个业务可以对应允许的一个位置区域或者多个位置区域。在一些实施例中，可以将UDM或PCF存储的业务标识信息指示的业务与第一位置信息指示的位置区域的对应关系称为业务签约数据。
这种场景下，当SMF接收来自终端设备的会话请求消息后，可以确定该会话请求消息用于请求的业务，例如第二业务，从而根据该第二业务的业务标识信息从UDM或PCF获取与第二业务对应的位置区域。例如，SMF可以向UDM或PCF发送请求第二消息，该第二消息用于获取第二业务的签约数据。UDM或PCF接收该第二消息，向SMF反馈与第二业务对应的位置区域，例如第二位置区域。应理解，UDM或PCF接收该第二消息，向SMF反馈的是与第二业务对应的签约数据，通过该签约数据，SMF可以获知第二业务所允许的第二位置区域。
上述两种应用场景中，SMF获知终端设备进行的第一业务以及该第一业务允许的第一位置区域之后，首先确定终端设备当前所在位置是否位于第一位置区域。例如，请参见图4为一种终端设备的位置示意图。在图4中，基站覆盖3个小区，这3个小区分别为小区1、小区2和小区3为例。体育馆是第一业务允许的第一位置区域。目前可以确定终端设备位于哪个小区，但是当该终端设备位于某个小区内，并不知道该终端设备位于该小区内的某个特定区域之外还是位于该特定区域之内。例如，请继续参见图4，终端设备当前位于小区3，但是并不知道终端设备位于体育馆内还是体育馆外。所以SMF可以进一步确定终端设备当前所在的位置，应理解，该位置的粒度比小区的粒度更细，也可以认为SMF可以确定对终端设备进行高精度定位。
例如，SMF可以获取终端设备当前的位置信息，根据该位置信息如果无法确定终端设备当前是否位于第一位置区域，那么SMF可以请求对终端设备进行高精度定位。例如，沿用图4所示的例子，如果SMF确定终端设备当前位于小区3，但是无法确定是位于小区3中的体育馆内还是体育馆外，那么SMF确定需要对终端设备进行高精度定位。
具体的，由于终端设备与SMF已建立会话，SMF可以将终端设备的标识与对应的会话关联，进而可以存储该终端设备的会话上下文，该会话上下文包括终端设备当前所在的位置的位置信息，例如Cell ID。在可能的实施方式中，SMF可以根据终端设备的标识查找 对应的会话上下文，并基于查找到的会话上下文获取终端设备当前的位置信息。如果SMF获取的终端设备当前的位置信息指示终端设备位于某个小区，那么SMF可以确定需要对终端设备进行高精度定位。
例如，在一个示例中，SMF可以向LMF发送第二消息，该第二消息用于请求获取终端设备当前所在的位置。LMF接收该第二消息，对终端设备进行定位，并将获取的终端设备的位置信息发送给SMF。
在另一个示例中，SMF可以向LMF发送第二消息，该第二消息可以用于订阅获取终端设备的位置的事件，以指示LMF定位上报终端设备当前所在的位置。例如第二消息可以包括时间信息，该时间信息用于指示LMF每隔例如第一时长向SMF上报终端设备当前所在的位置。LMF接收该第二消息，每隔第一时长对终端设备进行定位，并将获取的终端设备的位置信息发送给SMF。SMF不需要多次向LMF发送第二消息，就可以实现对终端设的定位，节省了SMF侧的信令开销。
应理解，上述两个示例中的第二消息包括终端设备的标识(UE ID)，以告知LMF定位哪个终端设备的位置。在一些实施例中，上述的第二消息还可以包括定位精度，用于指示需要定位的位置区域的半径。例如该定位精度可以是1米，那么终端设备当前的位置区域可以认为是以终端设备为中心，以1米为半径的区域。可选的，该定位精度可以根据第一位置区域确定。例如如果第一位置区域覆盖范围较大，那么定位精度指示的半径也可以较大；如果第一位置区域覆盖范围较小，那么定位精度指示的半径也可以较小。本申请实施例根据第一位置区域确定定位精度，可以更加准确地确定终端设备所在位置，更为准确地判断是否终止第一业务。
LMF接收来自SMF的第二消息，根据终端设备的标识对终端设备进行定位。具体的，LMF可以从终端设备和网络侧设备，例如基站获取用于定位终端设备的信息，例如信号测量强度等，利用定位计算方法，计算得到终端设备当前的位置。这里定位计算方法可以参见LMF定位的原理，这里不再赘述。应理解，如果第二消息为用于请求获取终端设备当前所在的位置的消息，那么LMF向SMF发送第三消息，该第三消息包括终端设备当前所在的位置信息。如果第二消息用于订阅获取终端设备的位置的事件，那么LMF定期向SMF发送第三消息，该第三消息包括终端设备当前所在的位置信息。
SMF接收第三消息，根据第三消息确定终端设备当前所在的位置是否位于第一位置区域。如果终端设备当前所在的位置位于第一位置区域，那么SMF确定允许第一业务；而如果终端设备当前所在的位置不在第一位置区域内，SMF可以确定需要终止第一业务，或者SMF也可以告知AF，终端设备当前不在第一位置区域，由AF确定是否终止第一业务。通过该方案，即通过定位比小区更细粒度的位置信息来管理终端设备进行的业务，例如在终端设备位于与业务关联的特定区域之外时，终止终端设备进行的业务，可以避免造成商家的损失。
前述实施例介绍了SMF根据LMF反馈的终端设备当前所在的位置确定终端设备是否在第一位置区域。不同于前述实施例，在另一些实施例中，LMF可以判断终端设备是否在第一位置区域，当确定终端设备不在第一位置区域，则告知SMF；相反，如果终端设备位于第一位置区域，那么LMF可以不向SMF上报终端设备的位置信息。采用这种方案，可以减轻SMF的负担，也节省了SMF的信令开销。
例如，SMF可以向LMF发送第二消息，该第二消息可以包括第一位置信息，该第一 位置信息用于指示第一位置区域。LMF接收该第二消息，可以定位终端设备当前所在位置，如果终端设备当前所在位置不在第一位置区域，那么LMF可以向SMF发送第三消息，该第三消息用于指示终端设备当前不在第一位置区域。SMF没有接收到第三消息，认为终端设备还处于第一位置区域，可以确定允许终端设备的会话，即允许终端设备进行第一业务。
在一些实施例中，该第二消息可以包括时间信息，该时间信息用于指示每隔多长时长，LMF对终端设备定位一次。LMF对终端设备定位之后，如果确定终端设备不在第一位置区域，那么向SMF发送第三消息。
又例如，可以事先定义终端设备离开第一位置区域时，通知SMF的事件，在下文中，将该事件称为第一事件。SMF可以向LMF发送第二消息，该第二消息可以用于订阅第一事件，应理解，该第二消息也可以认为是事件订阅消息。LMF接收该第二消息，可以定位终端设备当前所在位置，如果终端设备当前的位置位于第一位置区域内，那么LMF可以不向SMF上报。如果终端设备当前的位置不在第一位置区域内，LMF可以通知SMF，终端设备当前不在第一位置区域。例如，LMF可以向SMF发送第三消息，该第三消息可以是上述事件订阅消息的反馈消息，用于指示终端设备离开第一位置区域。这种情况可以理解为SMF请求LMF多次报告终端设备当前所在的位置，一旦终端设备当前不在第一位置区域内，LMF就主动向SMF上报。这样SMF可以通过发送一次事件订阅消息，实现LMF多次上报终端设备离开第一位置区域，节省了SMF的开销。同时，也可以使得SMF较为及时地管理第一业务。SMF没有接收到事件订阅消息的反馈消息，认为终端设备还处于第一位置区域，可以确定允许终端设备的会话，即允许终端设备进行第一业务。在S302中，SMF确定终端设备当前不在第一区域，可以确定需要终止第一业务。在可能的实施方式中，SMF可以向终端设备发送第四消息，该第四消息用于请求终止终端设备的会话，即终止第一业务。
在S303中，SMF确定终端设备当前不在第一区域，可以通知AF，终端设备不在第一位置区域。例如，SMF向AF发送第六消息，该第六消息用于通知AF终止第一业务。AF接收第六消息，可以终止第一业务。当然，AF接收第六消息，也可以确定不终止第一业务，例如进行第一业务的终端设备可能是会员，具有在第一位置区域之外进行第一业务的权限，更为合理。
在本申请实施例中，通过定位比小区更细粒度的位置信息来管理终端设备进行的业务，例如在终端设备位于与业务关联的特定区域之外时，断开终端设备进行的业务，以避免造成商家的损失。下面结合具体的应用场景，就图3所示的实施例所涉及的一些子方案分别进行举例介绍。
图5所示的流程以终端设备(UE)与SMF已经建立了一个会话，且获取了一种服务为例。
S501、UE与SMF建立了会话，SMF为该会话分配了UE IP地址。
S502、AF向GMLC发送配置请求消息，该配置请求消息包括AF的标识信息、UE的标识信息和位置区域信息。
由于UE已经建立了会话，且获取了一种服务，所以AF通过和UE的应用层通信，可以获知是哪个UE进行业务，以及该UE进行的业务。下文中，以UE进行的业务是第一业务为例。AF向GMLC发送的配置请求消息可以包括AF的标识信息、UE的标识信息和位置区域信息。其中，UE的标识信息可以指示具体是哪个UE，UE的标识信息例如可以 为UE IP地址、SUPI或者GPSI等。位置区域信息可以指示UE接入该第一业务允许的位置区域，例如为上述的第一位置区域。位置区域信息的实现可以参见上述第一信息的实现方式，这里不再赘述。
可选的，该配置请求消息还可以包括业务标识信息，用于指示UE接入的是哪个业务，例如业务标识可以是DNN，service ID，IP五元组等。
S503、GMLC根据配置请求消息对AF进行鉴权。
GMLC可以根据AF的标识信息对AF进行鉴权和授权。GMLC在对AF鉴权通过后，根据UE的标识，可以确定为UE服务的SMF。
S504、GMLC向SMF发送业务更新请求消息，该业务更新请求消息包括UE的标识信息和位置区域信息。
S505、SMF根据业务更新请求消息确定是否需要获取UE的第三位置区域。
由于UE与SMF已经建立了会话，UE的标识与对应的会话关联。而SMF保存有UE的会话上下文，该会话上下文包括UE当前所在位置，即第二位置区域的位置信息，例如Cell ID。SMF可以根据UE的标识获取对应的会话上下文，从该会话上下文获取第二位置区域。
SMF结合第二位置区域和S504中的位置区域信息所指示的第一位置区域，确定是否需要获取UE的第三位置区域。
如果第一位置区域位于第二位置区域内，即第一业务允许的位置区域的粒度比小区更细，那么SMF确定需要获取UE的第三位置区域。
S506、SMF向LMF发送第二消息，该第二消息用于请求获取UE的第三位置区域。
该第二消息可以包括UE的标识，LMF接收该第二消息，可以根据UE的标识对UE进行定位计算获得第三位置区域。
在一些实施例中，该第二消息还可以包括定位精度，用于指示第三位置区域的精度。LMF可以根据定位精度计算较为准确的第三位置区域。
S507、LMF执行UE的定位流程。
LMF可以从终端设备和网络侧设备，例如基站获取用于定位终端设备的信息，例如信号测量强度等，利用定位计算方法，计算得到终端设备的第三位置区域。其中，定位计算方法可以参见LMF定位的原理，这里不再赘述。
S508、LMF向SMF发送第三消息，该第三消息包括UE的第三位置区域。
第三消息可以认为是第二消息的响应消息，用于向SMF反馈第三位置区域。
S509、SMF根据第三位置区域和第一位置区域确定是否允许进行第一业务。
如果第三位置区域位于第一位置区域，那么SMF确定允许第一业务；而如果第三位置区域不在第一位置区域内，SMF可以确定需要终止第一业务。
S510、SMF向终端设备发送第四消息。
在可能的实施方式中，SMF可以向终端设备发送第四消息，该第四消息用于请求终止终端设备的会话，即终止第一业务。
可见，本申请实施例由于可以定位比小区更细粒度的位置信息来管理终端设备进行的业务，例如在终端设备位于与业务关联的特定区域之外时，断开终端设备进行的业务，以避免造成商家的损失。
图6所示的流程以UE还没有与SMF建立会话，即没有获取服务为例。
S601、AF向GMLC发送配置请求消息，该配置请求消息包括AF的标识信息、业务标识信息和位置区域信息。
该业务标识信息可以用于指示第一业务，例如业务标识信息可以是DNN，service ID，IP五元组等，但是不限定终端设备，具体可参见上述图3中的实施例的介绍。
S602、GMLC根据配置请求消息对AF进行鉴权。
GMLC可以根据AF的标识信息对AF进行鉴权和授权。
S603、GMLC向SMF发送业务更新请求消息，该业务更新请求消息包括业务标识信息和位置区域信息。
该业务标识信息指示第一业务，位置区域信息指示第一位置区域。GMLC对AF鉴权通过后，向SMF发送业务更新请求消息。
S604、SMF与终端设备建立会话。
SMF接收到终端设备发送的会话建立请求消息，该会话建立请求消息可以包括第一业务的标识信息。
S605、SMF向UDM或PCF发送请求获取第一业务对应的签约数据。
该签约数据包括与第一业务对应的第一位置区域。
S606、SMF根据第一位置区域和UE当前所在的第二位置区域确实是否需要获取UE当前所在的第三位置区域。
S607a、SMF确定需要获取第三位置区域，向LMF发送第二消息，该第二消息用于请求获取第三位置区域。
作为S607a的一种可替换的方案，S607b，SMF确定需要获取第三位置区域，向LMF发送第二消息，该第二消息为事件订阅消息，用于指示LMF确定UE不在第一位置区域时，通知SMF。
S608、LMF执行UE的定位流程。
S609a、LMF向SMF发送第三消息，该第三消息包括第三位置区域。
应理解，作为S609a的可替换的方案，S609b、LMF向SMF发送第三消息，该第三消息为事件订阅消息的反馈消息，用于指示UE不在第一位置区域。
S610、SMF根据第三位置区域和第一位置区域确定是否允许进行第一业务。
如果第三位置区域位于第一位置区域，那么SMF确定允许第一业务；而如果第三位置区域不在第一位置区域内，SMF可以确定需要终止第一业务。
S611、SMF向终端设备发送第四消息。
在可能的实施方式中，SMF可以向终端设备发送第四消息，该第四消息用于请求终止终端设备的会话，即终止已经建立的第一业务的会话。
应理解，作为S610的可替换的方案，如果终端设备还未与SMF建立会话连接，SMF接收到来自终端设备的会话建立请求，SMF可以拒绝建立与终端设备的会话。
图6的具体实现可以参见上述图3所述的实施例的介绍，这里不再赘述。
在本申请实施例中，可以通过定位比小区更细粒度的位置信息来管理终端设备进行的业务，例如在终端设备位于与业务关联的特定区域之外时，断开终端设备进行的业务，以避免造成商家的损失。同时，LMF一旦确定终端设备离开第一位置区域就通知SMF，即SMF可以通过发送一次事件订阅消息，实现LMF多次上报终端设备离开第一位置区域，节省了SMF的开销。
上述本申请提供的实施例中，分别从SMF、GMLC、LMF等网元之间交互的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，SMF、GMLC、LMF等网元可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
