具体实施方式

应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
本公开的发明人发现上述相关技术中存在如下问题：建网初期容易出现注册号段范围错误，造成用户无法使用SA网络，导致通信性能下降。
鉴于此，本公开提出了一种发现请求的处理技术方案，能够检测号段是否正确，以保证用户对SA网络的使用，从而提高通信性能。
如前说述，建网初期人工配置注册号段范围容易出现配置错误。例如，将注册号段范围配置为非归属地的本地用户的SUPI号段，甚至配置为全国号段。
在配置错误的情况下，在漫游场景下，拜访地的消费者网元在发现A地的生产者网元时因A地配置错误，得到了包含A地和B地号段的注册信息；这就导致B地用户漫游到拜访地，从拜访地接入时，服务请求会向A地发送，但A地没有B地用户的注册数据，最终导致B地用户无法使用SA网络。
针对上述技术问题，本公开提出一种在骨干网NRF网元上基于SUPI的注册号段反向检测技术方案。这样，可以检测发现流程中NRF网元返回的可提供服务的用户SUPI号段。从而，规避某地因号段配置错误导致其他地区用户无法使用SA网络的情况，提升网元动态发现准确性。
例如，可以通过如下的实施例实现本公开的技术方案。
图1示出本公开的发现请求的处理方法的一些实施例的流程图。
如图1所示，在步骤110中，接收漫游到拜访地的用户通过拜访地消费者网元发送的发现请求。例如，身份标识信息可以为SUPI等终端的唯一身份标识。
例如，消费者网元可以包括AMF(Access and Mobility Management Function,接入和移动性管理功能)网元、SMF(Session Management Function,会话管理功能)网元等。
在一些实施例中，在拜访地NRF网元根据用户的身份标识判断出用户为漫游用户的情况下，接收拜访地NRF网元转发的用户通过拜访地消费者网元发送的发现请求。
在步骤120中，根据发现请求中的用户的身份标识信息，将发现请求发送到用户的归属地NRF网元。
在一些实施例中，在5G的SA漫游场景下，用户接入拜访地(如拜访省)的5GC(核心网)时，拜访地消费者网元根据用户的SUPI号码，经过拜访地NRF网元、骨干网NRF网元、归属地(如归属省)NRF网元发现归属地目标生产者网元的注册信息。
例如，生产者网元包括UDM(Unified Data Management，统一数据管理功能)网元、PCF(Policy Control Function，策略控制功能)网元等。
例如，骨干NRF网元本地配置有各地的对应号段，能够根据用户的SUPI号码，向该用户的归属地NRF网元转发发现请求。
在步骤130中，根据归属地NRF网元返回的可提供服务的注册号段范围是否与预先存储的归属地的配置号段范围匹配，判断注册号段范围是否正确。例如，注册号段范围和配置号段范围均为SUPI等终端唯一身份标识的号段范围。
在一些实施例中，在归属地NRF网元根据用户的身份标识信息判断出用户为归属地用户的情况下，接收归属地NRF网元返回的可提供服务的注册号段范围。
在上述实施例中，骨干网NRF网元反向检测归属地NRF网元返回的注册号段范围是否正确，以保证用户对SA网络的使用，从而提高通信性能。
在一些实施例中，在配置号段范围包含注册号段范围的情况下，判断注册号段范围正确；在配置号段范围不包含注册号段范围的情况下，判断注册号段范围错误。例如，可以通过图2中的实施例实现本公开的技术方案。
图2示出图1的步骤130的一些实施例的流程图。
如图2所示，在步骤1310中，接收归属地NRF网元返回的可提供服务的注册号段范围。
在一些实施例中，归属地NRF网元将包括可提供服务的用户SUPI号段范围等注 册信息原路返回给骨干网NRF网元。
骨干网NRF网元收到归属地NRF网元返回的注册信息后，提取可提供服务的用户SUPI号段范围的最小值——注册号段min和最大值——注册号段max。
在步骤1320中，判断注册号段范围的最小值是否大于或等于配置号段范围的最小值，且小于配置号段范围的最大值。
在注册号段范围的最小值大于或等于配置号段范围的最小值，且小于配置号段范围的最大值的情况下，执行步骤1330；在注册号段范围的最小值小于配置号段范围的最小值，或者大于配置号段范围的最大值的情况下，执行步骤1340。
在一些实施例中，通过对注册号段min和骨干网NRF网元预先存储的各配置号段范围进行匹配，找出各配置号段范围中的一段配置SUPI号段范围中的配置号段min和配置号段max。
例如，先判断注册号段范围是否满足判断条件——配置号段min≤注册号段min<配置号段max；在满足的情况下，再判断注册号段范围是否满足判断条件——注册号段max<配置号段max。
在步骤1330中，根据注册号段范围的最大值和配置号段范围的最大值，判断注册号段范围是否正确。
在注册号段范围的最大值大于配置号段范围的最大值的情况下，执行步骤1340；在注册号段范围的最大值小于或等于配置号段范围的最大值的情况下，执行步骤1350。
在步骤1340中，判断注册号段范围错误。
在步骤1350中，判断注册号段范围正确。
在判断出注册号段范围是否正确后，可以通过图1中的剩余步骤继续处理发现请求。
在步骤140中，根据判断结果，向拜访地消费者网元返回发现请求的响应信息。
在一些实施例中，在判断注册号段范围错误的情况下，向拜访地消费者网元发送失败响应，以便拜访地消费者网元不缓存注册号段范围；在判断注册号段范围正确的情况下，向拜访地消费者网元发送归属地NRF网元返回的归属地生产者网元的注册信息，以便拜访地消费者网元根据注册信息处理发现请求。
在一些实施例中，如果判断为合法的注册号段范围，则将归属地NRF网元返回的注册信息返回至拜访地NRF网元；如果判断为非法的注册号段范围，则向拜访地NRF网元返回发现失败响应。
例如，拜访地消费者网元不会缓存归属地配置的错误号段范围，可以向网管系统提出号段配置错误告警，由维护人员即时确认并修改号段配置。
例如，在发现流程中，消费者网向NRF网元发送发现请求；消费者网元将NRF网元返回的生产者网元的注册信息在本地缓存一定时间以减少重复发现的过程。在服务请求流程中，消费者网元根据生产者网元的注册信息，选择相应的生产者网元，并向该生产者网元发送服务请求。
图3示出本公开的发现请求的处理方法的一些实施例的示意图。
如图3所示，在步骤0(图中未示出)中，骨干网NRF网元上配置有各地的SUPI配置号段范围。
例如，A省的配置号段范围为000-099，B省的配置号段范围为100-199等。
在一些实施例中，由于注册号段范围配置错误，B省的UDM网元向B省的NRF网元注册时携带了错误的注册号段范围000-199。
在步骤1中，B省的用户(其SUPI＝111)漫游到A省，A省的AMF网元向A省的NRF网元发送发现请求。发现请求用于请求能为该用户提供服务的UDM网元的地址信息。
在步骤2中，A省的NRF网元根据用户的SUPI，发现该用户的SUPI不在A省的配置号段范围内，即不是A省的用户，将发现请求转发至骨干网NRF网元。
在步骤3中，骨干网NRF网元根据用户的SUPI，发现该用户的SUPI在B省的配置号段范围内，将该发现请求转发至用户的归属地——B省的NRF网元。
在步骤4中，B省的NRF网元根据用户的SUPI，发现该用户为B省的用户，将错误的注册号段范围(000-199)包含在注册信息中向骨干网NRF网元返回。例如，注册信息中还包含B省(归属地)生产者网元的注册信息。
在步骤5中，骨干网NRF网元收到注册信息后，提取出注册号段min＝000，注册号段max＝199。
在步骤6中，找出在骨干网NRF网元中配置的A省的配置号段范围的最小值和最大值——配置号段min＝000，配置号段max＝099，并判断出满足配置号段min≤注册号段min<配置号段max。
在步骤7中，比较注册号段max和配置号段max，发现注册号段max>配置号段max，因此判断为非法注册号段范围。
在步骤8b中，向拜访省的NRF网元返回发现失败响应。
在一些实施例中，如果判断为合法注册号段范围，则执行步骤8a，向拜访省的NRF网元返回归属省的UDM网元的注册信息作为请求响应，以便用户通过该UDM网元的注册信息处理发行请求。
在步骤9中，拜访省的NRF网元向拜访省的AMF网元返回发现失败响应。AMF网元不会缓存错误号段，因此不会影响A省用户使用SA网络。
通过上述实施例能够避免下面的情况：若不通过此方法检测出错误注册号段范围，拜访省的AMF网元会将错误的注册号段范围000-199对应到B省的UDM网元；当A省用户(SUPI＝011)接入时，AMF网元向B省UDM网元请求用户信息，而B省没有该A省用户信息，将返回鉴权失败，导致A省用户无法使用SA网络。
上述实施例中，骨干网NRF网元提取归属地NRF网元返回的注册信息中可提供服务的用户SUPI注册号段范围；骨干网NRF网元通过匹配和比较本地配置号段范围和注册号段范围，判断非法注册号段范围，返回发现失败响应。
这样，能够有效规避因生产者网元注册过程中号段配置错误导致用户无法使用网络的技术问题。
例如，可以由4G核心网HDRA中导出全国号段，并导入5G核心网骨干网NRF网元中作为配置号段范围，用于将发现请求转发至归属地。这样，能够降低号段范围的配置出错几率。
例如，骨干网NRF网元通过匹配配置号段范围与注册信息中可提供服务的用户SUPI号段(注册号段范围)，反向检测注册号段范围是否正确。这样，可以阻止包含错误号段范围的注册信息返回拜访地消费者网元，从而提升网元动态发现准确性。
在一些实施例中，拜访地消费者网元通过拜访地NRF网元，向骨干网NRF网元发送漫游到拜访地的用户的发现请求；骨干网NRF网元根据发现请求中的用户的身份标识信息，将发现请求发送到用户的归属地NRF网元；归属地NRF网元向骨干网NRF网元返回归属地生产者网元可提供服务的注册号段范围；骨干网NRF网元根据注册号段范围是否与预先存储的归属地的配置号段范围匹配，判断注册号段范围是否正确；骨干网NRF网元根据判断结果，向拜访地消费者网元返回发现请求的响应信息。

在一些实施例中，发送单元42在判断注册号段范围错误的情况下，向拜访地消费者网元发送失败响应，以便拜访地消费者网元不缓存注册号段范围；在判断注册号段范围正确的情况下，向拜访地消费者网元发送归属地NRF网元返回的归属地生产者网元的注册信息，以便拜访地消费者网元根据注册信息处理发现请求。
判断单元43根据归属地NRF网元返回的可提供服务的注册号段范围是否与预先存储的归属地的配置号段范围匹配，判断注册号段范围是否正确。
在一些实施例中，判断单元43在配置号段范围包含注册号段范围的情况下，判断注册号段范围正确；在配置号段范围不包含注册号段范围的情况下，判断注册号段范围错误。
在一些实施例中，判断单元43判断注册号段范围的最小值是否大于或等于配置号段范围的最小值，且小于配置号段范围的最大值；在注册号段范围的最小值小于配置号段范围的最小值，或者大于配置号段范围的最大值的情况下，判断注册号段范围错误；在注册号段范围的最小值大于或等于配置号段范围的最小值，且小于配置号段范围的最大值的情况下，根据注册号段范围的最大值和配置号段范围的最大值，判断注册号段范围是否正确。
在一些实施例中，判断单元43在注册号段范围的最大值大于配置号段范围的最大值的情况下，判断注册号段范围错误；在注册号段范围的最大值小于或等于配置号段范围的最大值的情况下，判断注册号段范围正确。
