Description

业务处理方法、设备及系统 技术领域
本申请涉及通信领域，尤其涉及业务处理方法、设备及系统。
背景技术
目前，在移动通信系统中，网络设备对终端设备执行业务管理的范围由若干小区构成。
然而，小区对应的地理范围很大，其直径通常为几百米至数公里。因此，现有技术中对终端设备执行业务管理的地理范围较大，其直径可能长达数十公里，这使得网络设备对终端设备的业务管理不够精细化。
发明内容
本申请实施例提供的业务处理方法、设备及系统，能够对终端设备执行更加精细化的业务管理。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种业务处理方法，该方法包括：第一网元向第二网元发送第一消息，该第一消息用于请求获取终端设备的位置信息；第一网元接收来自第二网元的位置信息；第一网元根据位置信息确定终端设备是否位于第一非限制区域内；若终端设备位于第一非限制区域内，第一网元允许终端设备获取业务；若终端设备不位于第一非限制区域内，第一网元不允许终端设备获取业务。由于该方案中，第一网元可以基于终端设备的位置信息对终端设备进行业务管理，因此可以在较小的地理范围内对终端设备执行精细化的业务管理。避免了现有技术中，对终端设备的业务管理不够精细化的问题。
在一种可能的设计中，该第一网元包括接入与移动管理功能网元或会话管理功能网元，该第二网元包括位置管理功能网元。
在一种可能的设计中，在第一网元向第二网元发送第一消息之前，该方法还包括：第一网元确定终端设备位于第二非限制区域内，第二非限制区域的范围为跟踪区范围或者小区范围。即，第一网元先确定终端设备位于第二非限制区域之后，才获取终端设的位置信息，进而根据终端设备的位置信息对其进行业务管理。因此，基于该方案，能够避免第一网元执行不必要的流程，从而减少网络资源消耗。
可选的，第一非限制区域的范围小于第二非限制区域的范围。
在一种可能的设计中，在第一网元确定终端设备位于第二非限制区域内之后，该方法还包括：第一网元向终端设备发送注册接受消息，注册接受消息中携带第一指示信息，第一指示信息用于指示终端设备当前不能获取业务。基于该方案，在第一网元确定终端设备位于第一非限制区域之前，终端设备不能获取业务。
在一种可能的设计中，第一网元允许终端设备获取业务，包括：第一网元向终端设备发送第二指示信息，第二指示信息用于指示终端设备恢复获取业务。基于该方案，在该第二指示信息的指示下，终端设备能够获取业务。
在一种可能的设计中，在第一网元根据位置信息确定终端设备是否位于第一非限制区域内之前，该方法还包括：若第一网元接收到来自终端设备的第二消息，第一网元拒绝终端设备获取业务，第二消息用于请求建立会话或者第二消息用于请求业务。基于该方案，在第一网元确定终端设备位于第一非限制区域之前，终端设备无法获取业务。
在一种可能的设计中，在第一网元确定终端设备位于第二非限制区域内之后，该方法还包括：第一网元对终端设备执行切换流程；相应的，第一网元向第二网元发送第一消息，包括：第一网元确定执行完对终端设备的切换流程后，向第二网元发送第一消息。即，在切换场景中，当终端设备位于第二非限制区域时，可以先对终端设备执行切换，切换完成后再获取终端设备的具体位置信息，基于该位置信息对终端设备进行业务处理。
在一种可能的设计中，在第一网元确定终端设备位于第二非限制区域内之后，该方法还包括：第一网元向第三网元发送第三指示信息，第三指示信息用于指示第三网元当前不能传输终端设备的用户面数据。其中，该第三网元包括用户面功能网元或终端设备切换后接入的接入网网元。即，在切换场景中，虽然允许终端设备进行切换，但在第一网元确定终端设备位于第一非限制区域之前，不传输终端设备的用户面数据，从而使得终端设备不能获取业务。
在一种可能的设计中，第一网元允许终端设备获取业务，包括：第一网元向第三网元发送第四指示信息，第四指示信息用于指示第三网元恢复传输终端设备的用户面数据。基于该方案，根据该第四指示信息的指示，即可恢复传输终端设备的用户面数据，使得终端设备能够获取业务。
在一种可能的设计中，第一网元接收来自第二网元的位置信息，包括：第一网元接收第二网元周期性发送的位置信息。基于该方案，每当第一网元接收到终端设备的位置信息后，即可按照该方法对终端设备进行实时的业务处理。
可选的，该方法用于会话建立流程、业务请求流程、注册流程或切换流程。
可选的，该方法用于会话建立流程时，第一网元允许终端设备获取业务，包括：第一网元允许执行会话建立流程；第一网元不允许终端设备获取业务，包括：第一网元发起会话删除流程或者拒绝会话建立流程。其中，第一网元拒绝会话建立流程，具体包括：第一网元向终端设备发送第三消息，第三消息用于通知终端设备第一网设备已经拒绝建立会话；或者，第一网元向会话管理功能网元发送第三消息，第三消息用于通知会话管理功能网元拒绝建立会话。
可选的，该方法用于业务请求流程时，第一网元确定允许终端设备获取业务，包括：第一网元允许执行业务请求流程；第一网元确定不允许终端设备获取业务，包括：第一网元发起接入网释放流程或者拒绝业务请求流程。
可选的，在第一网元确定终端设备不位于第一非限制区域内之后，该方法还包括：第一网元向会话管理功能网元发送终端设备的位置信息。基于该方案，会话管理功能网元通过会话签约信息获取到第一非限制区域的信息后，即可确定终端设备当前是否位于第一非限制区域内，并在终端设备不位于第一非限制区域内时拒绝终端设备的会话建立请求。

具体实施方式
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。其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“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，其中A,B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达，是指的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，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。同时，在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
如图1所示，为本申请实施例提供的一种通信系统10，该通信系统10包括第一网元101和第二网元102。第一网元101和第二网元102之间可以直接通信，也可以通过其他设备的转发进行通信，本申请实施例对此不作具体限定。
其中，第一网元101，用于向第二网元102发送第一消息，该第一消息用于请求获取终端设备的位置信息。第二网元102，用于接收来自第一网元101的第一消息，向第一网元101发送终端设备的位置信息。第一网元101，还用于接收来自第二网元102的位置信息，进而根据位置信息确定终端设备是否位于第一非限制区域内；第一网元101，还用于若终端设备位于第一非限制区域内，允许终端设备获取业务；或者，第一网元101，还用于若终端设备不位于第一非限制区域内，不允许终端设备获取业务。其中，上述方案的具体实现将在后续方法实施例中详细阐述，在此不予赘述。
由于本申请实施例中，第一网元通过向第二网元发送请求获取终端设备的位置信息的第一消息之后，能够获得终端设备的位置信息，进而第一网元可以根据终端设备的位置信息确定终端设备是否位于第一非限制区域内，若终端设备位于第一非限制区域内，则允许终端设备获取业务；否则，不允许终端设备获取业务。也就是说，本申请实施例中，第一网元可以基于终端设备的位置信息对终端设备进行业务管理，因此可以在较小的地理范围内对终端设备执行精细化的业务管理。避免了现有技术中，对终端设备的业务管理不够精细化的问题。
可选的，如图2所示，本申请实施例提供的通信系统10除了包括图1所示的第一网元101和第二网元102之外，还可以包括第三网元103。其中，第三网元103为用户面网元或终端设备的目标接入网网元。
其中，第一网元101，还用于向第三网元103发送第三指示信息，第三指示信息用于指示第三网元103当前不能传输终端设备的用户面数据。第三网元103，用于接收来自第一网元101的第三指示信息，进而根据第三指示信息的指示，丢弃终端设备的用户面数据。
可选的，第一网元101，还用于向第三网元103发送第四指示信息，第四指示信息用于指示第三网元103恢复传输终端设备的用户面数据。第三网元103，还用于接收来自第一网元101的第四指示信息，进而根据第四指示信息的指示，恢复传输终端设备的用 户面数据。
此外，需要说明的是，本申请实施例描述的网络架构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。比如，图1所示的通信系统10可以应用于目前第五代(the 5th generation，5G)移动网络，也可以应用于长期演进(long term evolution，LTE)移动网络、MulteFire网络、家庭基站网络、Wi-Fi接入的移动网络、或者未来(the 6th generation，6G)网络，固移融合网络等，本申请实施例对此不作具体限定。

其中，如图3所示，终端设备通过N1接口(简称N1)与AMF网元通信，下一代接入网网元通过N2接口(简称N2)与AMF网元通信，下一代接入网网元通过N3接口(简称N3)与UPF网元通信，UPF网元通过N6接口(简称N6)与数据网络(data network，DN)通信，AMF网元通过N15接口(简称N15)与PCF网元通信，AMF网元通过N11接口(简称N11)与SMF网元通信，SMF网元通过N7接口(简称N7)与PCF网元通信，SMF网元通过N10接口(简称N10)与UDM网元通信，SMF网元通过N4接口(简称N4)与UPF网元通信。
其中，需要说明的是，LMF网元可以独立部署，也可以和AMF网元、或者下一代接入网网元、或者SMF网元共同部署在一个设备上，本申请实施例对此不作具体限定。
可选的，本申请实施例中的第一网元101的相关功能可以由一个设备实现，也可以由多个设备共同实现，还可以是由一个设备内的一个或多个功能模块实现，本申请实施例对此不作具体限定。可以理解的是，上述功能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，或者是硬件与软件的结合，或者是平台(例如，云平台)上实例化的虚拟化功能。
例如，本申请实施例中的第一网元101的相关功能可以通过图4中的通信设备400来实现。图4所示为本申请实施例提供的通信设备400的结构示意图。该通信设备400包括一个或多个处理器401，通信线路402，以及至少一个通信接口(图4中仅是示例性的以包括通信接口404，以及一个处理器401为例进行说明)，可选的还可以包括存储器403。

存储器403可以是具有存储功能的装置。例如可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器可以是独立存在，通过通信线路402与处理器相连接。存储器也可以和处理器集成在一起。
其中，存储器403用于存储执行本申请方案的计算机执行指令，并由处理器401来控制执行。处理器401用于执行存储器403中存储的计算机执行指令，从而实现本申请实施例中提供的业务处理方法。
或者，可选的，本申请实施例中，也可以是处理器401执行本申请下述实施例提供的业务处理方法中的处理相关的功能，通信接口404负责与其他设备或通信网络通信，本申请实施例对此不作具体限定。
可选的，本申请实施例中的计算机执行指令也可以称之为应用程序代码，本申请实施例对此不作具体限定。
在具体实现中，作为一种实施例，处理器401可以包括一个或多个CPU，例如图4中的CPU0和CPU1。
在具体实现中，作为一种实施例，通信设备400可以包括多个处理器，例如图4中的处理器401和处理器407。这些处理器中的每一个可以是一个单核(single-CPU)处理器，也可以是一个多核(multi-CPU)处理器。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。

上述的通信设备400有时也可以称为通信装置，其可以是一个通用设备或者是一个专用设备。例如通信设备400可以是台式机、便携式电脑、网络服务器、掌上电脑(personal digital assistant，PDA)、移动手机、平板电脑、无线终端设备、嵌入式设备、家庭网关(residential gateway，RG)、上述终端设备，上述网络设备、或具有图4中类似结构的设备。本申请实施例不限定通信设备400的类型。
下面将结合图1至图4对本申请实施例提供的业务管理方法进行具体阐述。
需要说明的是，本申请实施例提供的业务处理方法可以用于会话建立流程、业务请求流程、注册流程或切换流程等，并且本申请下述实施例中各个网元之间的消息名字或消息中各参数的名字等只是一个示例，具体实现中也可以是其他的名字，本申请实施例对此不作具体限定。
以图1所示的通信系统应用于图3所示的5G网络，第一网元为AMF网元，第二网元为LMF网元为例，如图5所示，为本申请实施例提供的一种业务处理方法，可应用于注册流程，包括如下步骤：
S501、终端设备向NG-RAN网元发送注册请求消息；NG-RAN网元接收来自终端设备的注册请求消息。
S502、NG-RAN网元选择AMF网元，并向AMF网元发送注册请求消息；AMF网元接收来自NG-RAN的注册请求消息。
S503、AMF网元确定终端设备是否位于允许接入的第二非限制区域内。
其中，第二非限制区域的范围为跟踪区范围或者小区范围。该第二非限制区域用于限定网络侧设备允许终端设备接入的范围，可以是现有技术中对该终端设备进行业务处理的地理范围。可选的，AMF网元可以从UDM网元或PCF网元获取该第二非限制区域的信息，本申请实施例对此不作具体限定。
示例性的，若第二非限制区域为跟踪区范围，则AMF网元可以通过确定终端设备当前所在小区是否属于该跟踪区范围，确定终端设备是否位于第二非限制区域内。若第二非限制区域为小区范围，则AMF网元可以通过确定终端设备当前所在小区是否为第二非限制区域对应的小区，确定终端设备是否位于第二非限制区域内。
其中，步骤S501-S503的相关实现可参考现有技术，在此不予赘述。
进一步的，基于上述步骤S503，当AMF网元确定终端设备不位于该第二非限制区域后，则直接向终端设备发送注册拒绝消息，不再对终端设备进行注册(如图5中的步骤S504a)。当AMF网元确定终端设备位于该第二非限制区域后，则对终端设备进行注册，进而从第二网元获取终端设备的位置信息，根据终端设备的位置信息对其进行业务处理(即执行图5中的步骤S504b-S512b)。这样，可以避免AMF网元由于执行不必要的流程(如注册流程、定位流程)所导致的网络资源消耗。
其中，如图5所示，步骤S504a包括：
S504a、AMF网元向终端设备发送注册拒绝消息；终端设备接收来自AMF网元的注册拒绝消息。
其中，步骤S504a的相关实现可参考现有技术，在此不予赘述。
其中，如图5所示，步骤S504b-S510b包括：
S504b、AMF网元及其他相关5G核心网(5G core，5GC)网元完成对终端设备的注册。
S505b、AMF网元向终端设备发送注册接受消息；终端设备接收来自AMF网元的注册接受消息。
其中，注册接受消息中携带第一指示信息，第一指示信息用于指示终端设备当前不能获取业务。示例性的，第一指示信息具体可以是业务禁止指示(service forbidden  indication)，本申请实施例对此不作具体限定。可选的，注册接受消息中还可以携带原因值，该原因值用于说明网络暂未识别出终端设备处于第一非限制区域。
需要说明的是，本申请实施例中，终端设备当前不能获取业务具体是指不允许终端设备通过执行会话建立流程和/或业务请求流程来获取业务。
S506b、AMF网元选择LMF网元。
S507b、AMF网元向LMF网元发送第一消息；LMF网元接收来自AMF网元的第一消息。
其中，第一消息用于请求获取终端设备的位置信息。示例性的，第一消息例如可以是定位请求消息(Nlmf_location_Determinlocation Request)，该定位请求消息用于请求对终端设备周期性执行位置服务(location services，LCS)。可选的，该定位请求消息中还可以包括执行LCS的周期值。
S508b、LMF网元对终端设备执行定位流程，以获取终端设备的位置信息。
一种可能的实现方式中，LMF网元可通过对终端设备周期性执行LCS获取终端设备的位置信息。
S509b、LMF网元向AMF网元发送终端设备的位置信息；AMF网元接收来自LMF网元的终端设备的位置信息。
需要说明的是，本申请实施例中，若LMF网元通过对终端设备周期性执行LCS获取终端设备的位置信息，则在每次LMF网元获取终端设备的位置信息之后，均需要执行上述步骤S509b，即LMF网元周期性的向AMF网元发送终端设备的位置信息，AMF网元接收来自LMF网元周期性发送的终端设备的位置信息。
S510b、AMF网元根据终端设备的位置信息确定终端设备是否位于第一非限制区域内。
其中，第一非限制区域的范围小于第二非限制区域的范围。示例性的，可通过经纬度信息、行政区域信息、运营商自定义的位置信息等限定第一非限制区域的范围，本申请实施例对此不作具体限定。可选的，AMF网元可以从UDM网元或PCF网元获取该第一非限制区域的信息，本申请实施例对此不作具体限定。
一种可能的实现方式中，若终端设备不位于第一非限制区域内，则本申请实施例提供的业务处理方法包括如下步骤S511b：
S511b、AMF网元对终端设备执行去注册流程。
即，AMF网元通过对终端设备执行去注册流程，实现不允许终端设备获取业务。
或者，另一种可能的实现方式中，若终端设备位于第一非限制区域内，则本申请实施例提供的业务处理方法包括如下步骤S512b：
S512b、AMF网元向终端设备发送第二指示信息；终端设备接收来自AMF网元的第二指示信息。
其中，第二指示信息用于指示终端设备恢复获取业务。示例性的，第二指示信息具体可以是业务禁止取消指示(service forbidden cancel indication)，本申请实施例对此不作具体限定。
即，AMF网元通过向终端设备发送第二指示信息，实现允许终端设备获取业务。需要说明的是，本申请实施例中，允许终端设备获取业务具体是指允许终端设备通过执行会话建立流程和/或业务请求流程获取业务。
可选的，本申请实施例中，在AMF网元根据终端设备的位置信息确定终端设备是否位于第一非限制区域内(即步骤S510b)之前，本申请实施例提供的业务处理方法还包括：若AMF网元接收到来自终端设备的第二消息，AMF网元拒绝终端设备获取业务。其中，第二消息用于请求建立会话或者第二消息用于请求业务。
即，在AMF网元确定终端设备是否位于第一非限制区域内之前，若AMF网元接收到终端设备的会话建立请求或者业务请求，AMF网元也将拒绝终端设备的会话建立请求或者业务请求，以达到不允许终端设备获取业务的目的。
由于本申请实施例中，AMF网元通过向LMF网元发送请求获取终端设备的位置信息的第一消息，能够获取来自LMF网元的位置信息，进而AMF网元根据终端设备的位置信息确定终端设备是否位于第一非限制区域内，若终端设备位于第一非限制区域内，则向终端设备发送第二指示信息，以允许终端设备获取业务；否则，AMF网元对终端设备执行去注册流程，以不允许终端设备获取业务。也就是说，本申请实施例中，AMF网元可以基于终端设备的位置信息对终端设备进行业务管理，因此可以在较小的地理范围内对终端设备执行精细化的业务管理。避免了现有技术中，对终端设备的业务管理不够精细化的问题。
