无线接入网网元12可以称为以下至少一项:无线接入网设备、无线接入 网节点、无线接入网功能、无线接入网单元;无线接入网网元12可以包含但不限于至少以下之一:无线接入网设备、无线接入网节点、无线接入网功能、无线接入网单元、第三代合作伙伴计划(Third Generation Partnership Project,3GPP)无线接入网、非3GPP无线接入网、集中单元(Centralized Unit,CU)、分布式单元(Distributed Unit,DU)、基站、演进型基站(evolved Node B,eNB)、第五代(5

可选的,本申请实施例可以应用于4G、5G、6G等通信系统。
为了便于理解本申请,首先说明以下内容。
Local NEF是引入的一个新的本地化网元。Local NEF的功能包括:为本地的AF提供快速的服务质量(Quality of Service,QoS)监控。如图2所示,在未引入Local NEF的情况下,当本地协议数据单元(Protocol Data Unit,PDU)会话锚点(local PDU Session Anchor,local PSA)生成了QoS监控报告以后,需要先通过N4接口发送给SMF,然后通过PCF和NEF转一圈后发送给AF。其中,所述local PSA是部署在本地,跟AF和UE位置较为接近,如图2所述,部署在local数据中心(Data Center,DC);而PCF、SMF、NEF等网元都部署在中心机房(如图2所述,部署在Central DC),一般是在省级中心机房,距离较远。而在引入Local NEF后,local PSA可以直接把生成的QoS监控报告通过Nx接口发送给Local NEF,然后由local NEF把QoS监控报告发给AF。这样,由于UE,local PSA,local NEF,AF等都在本地,位置上较为接近,因此可以大大节约信令的绕行过程,提高通信效率。
然而,AF如何发现local NEF,并建立QoS会话(AF session with QoS),目前是未知的。另外,考虑到AF可能一开始并不知道local NEF的网际协议(Internet Protocol,IP)地址,因此,为了发现/确定local NEF,AF可以先触发一个会话QoS建立请求到NEF,该NEF是一个初始NEF,即可能不是本地化网元,不是最优的,然后再确定local NEF。
另外,考虑到在local NEF的寻找过程中,需要数据网接入标识(Data Network Access Identifier,DNAI)、跟踪区标识(Tracking Area Identity,TAI)、小区标识(cell ID)等终端位置信息,AF对DNAI可能是已知的,但是TAI、cell ID等信息是保存在与终端相关联的AMF中,因此,如何获取TAI、cell ID等终端位置信息也是目前急需解决的问题。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的服务确定方法、装置、网络功能及可读存储介质进行详细地说明。
请参见图3,图3是本申请实施例提供的一种服务确定方法的流程图,该方法由第一网络功能执行,该第一网络功能可选为NEF等,该NEF比如为初始NEF(initial NEF),即AF内保存的一个NEF,而这个NEF并不一定 是local NEF。如图3所示,该方法包括如下步骤:
步骤31:第一网络功能根据第一信息,确定服务终端和/或第二网络功能的本地网络功能。
一些实施例中,第一网络功能为initial NEF,第二网络功能为AF。
一些实施例中,本地网络功能为本地NEF,即local NEF或L-NEF。由此在确定local NEF之后,可以通过Local NEF,将local PSA生成的QoS监控报告直接发给AF,从而相比于现有技术中的借助SMF、PCF、NEF等网元转发QoS监控报告至AF,可以大大节约信令的绕行过程,提高通信效率。
可选的,上述的第一信息可以包括但不限于以下至少一项:
第一指示;
边缘事件;
预先存储的终端位置和/或第二网络功能位置对应的本地网络功能的地址信息。
在本申请实施例中,第一网络功能可以根据第一信息,确定服务终端和/或第二网络功能的本地网络功能,该第一信息包括以下至少一项:第一指示、边缘事件、预先存储的终端位置和/或第二网络功能位置对应的本地网络功能的地址信息。由此,可以确定提供服务的本地网络功能。
可选的,在本申请实施例中,第一网络功能可以接收会话QoS建立请求,比如从第二网络功能接收会话QoS建立请求。该会话QoS建立请求中包括第一指示和/或第一参数,第一参数用于组成网络为第二网络功能提供的边缘事件,或者,第一参数包含在网络为第二网络功能提供的边缘事件中。
一些实施例中,NEF可以从AF接收会话QoS建立请求。
需说明的,为了确定提供服务的本地网络功能,至少存在以下情况:
1)在第二网络功能向第一网络功能请求会话QoS的建立的时候,在相应请求(如AF session with QoS request)中携带一个指示(indication)如上述的第一指示,以便第一网络功能根据第一指示,确定服务终端和/或第二网络功能的本地网络功能。
可选的,第一指示可以用于指示以下至少一项:
基于终端位置和/或第二网络功能位置,选择服务终端的本地网络功能(如L-NEF);
基于终端位置和/或第二网络功能位置,选择服务第二网络功能的本地网络功能;
选择从终端到第二网络功能的路由最佳的本地网络功能(如L-NEF);
请求终端的位置信息,比如可以先确定服务终端的AMF,再向AMF订购终端位置;
包括第一指示的请求是用于请求提供边缘业务或边缘服务。
一些实施例中,第一网络功能可以直接接收第一指示,该第一指示用于请求提供边缘业务或边缘服务,并根据该第一指示,确定服务终端和/或第二网络功能的本地网络功能。
2)在第二网络功能向第一网络功能请求会话QoS的建立的时候,在相应请求(如AF会话QoS请求(AF session with QoS request))中不携带indication,而是携带第一参数,该第一参数用于组成网络为第二网络功能提供的边缘事件,或者,该第一参数包含在网络为第二网络功能提供的边缘事件中,以便第一网络功能根据边缘事件,确定服务终端和/或第二网络功能的本地网络功能。
一些实施例中,第一参数可以包括但不限于以下至少一项:
用于边缘或提供边缘服务的上下行包延迟;
用于边缘或提供边缘服务的单用户面(User Plane,UP)路径的往返时延;
用于边缘或提供边缘服务的双UP路径的往返时延;
突发数据包的尺寸。
可选的,上述边缘事件可以为:第二网络功能请求网络为其提供边缘服务,网络通过本地网络功能为终端和/或第二网络功能提供边缘服务。
可选的,上述边缘事件可以包括以下至少一项:
边缘QoS监控;其中,该边缘QoS监控可以包括:边缘QoS监控报告/ 上报;
边缘计算服务(edge computing service)。比如,该边缘计算服务可以包括以下至少一项:边缘QoS建立、边缘路由等。
也就是说,在现有QoS监控事件(QoS monitoring event)的基础上,可以引入一个新的边缘事件,比如边缘QoS监控报告,这样基于引入的新的边缘事件,第一网络功能发现需要为这个边缘事件选择一个本地网元,因此,可以获知为终端和/或发起请求的第二网络功能选择一个本地网络功能。
3)在第一网络功能接收到某终端位置和/或第二网络功能位置对应的第二网络功能发送的会话QoS建立请求,且根据这一请求确定提供服务的本地网络功能后,保存该终端位置和/或第二网络功能位置对应的本地网络功能的地址信息,以便后续在该终端位置和/或第二网络功能位置对应的第二网络功能再发送会话QoS建立请求后,第一网络功能发现触发该请求的第二网络功能,与所保存的第二网络功能处于相同的位置之后,直接响应,即将存储的地址信息对应的本地网络功能,直接确定为服务终端和/或第二网络功能的本地网络功能。这样,借助第一网络功能的缓存功能,可以快速确定提供服务的本地网络功能,以避免重复查找操作。
可选的,上述终端位置和/或第二网络功能位置的指示信息可以包括但不限于以下至少一项:终端的地址信息、cell ID、DNAI、TAI、数据网名称(Data Network Name,DNN)、单一网络切片选择辅助信息(Single Network Slice Selection Assistance Information,S-NSSAI)、终端IP地址、终端IP地址段等。
可选的,若第一信息包括:预先存储的终端位置和/或第二网络功能位置对应的本地网络功能的地址信息,第一网络功能已接收过该终端位置和/或第二网络功能位置对应的第二网络功能发送的会话QoS建立请求,上述根据第一信息,确定服务终端和/或第二网络功能的本地网络功能的过程可以包括:当第一网络功能再次接收到该终端位置和/或第二网络功能位置对应的第二网络功能发送的会话QoS建立请求时,第一网络功能将预先存储的地址信息对应的本地网络功能,确定为服务终端和/或第二网络功能的本地网络功能。
比如,NEF在收到AF的会话QoS建立请求后,若发现触发该请求的AF与所存储的AF处于相同的位置,其中,该存储的AF先前已向NEF发送了会话QoS建立请求,并根据这个请求找到了一个local NEF,并存储了该local NEF的地址信息,则可以将预先存储的地址信息对应的local NEF直接确定为提供服务的local NEF。
可选的,当第一信息包括第一指示和/或边缘事件时,第一网络功能在根据第一信息,确定服务终端和/或第二网络功能的本地网络功能时,可以首先,根据第一指示和/或边缘事件,获取第三网络功能的标识和/或地址信息;然后,根据该第三网络功能的标识和/或地址信息,获取终端的位置信息;最后,根据该终端的位置信息,选择服务终端和/或第二网络功能的本地网络功能。这样在本地网络功能的选择过程中,可以获取终端的位置信息,并根据获取的终端的位置信息,选择服务终端和/或第二网络功能的本地网络功能。
可选的,在获取第三网络功能的标识和/或地址信息时,可以借助对BSF或者UDM发起请求,来获取第三网络功能的标识和/或地址信息,该地址信息比如为IP地址。
一种实施方式中,当借助BSF获取第三网络功能的标识和/或地址信息时,第一网络功能可以向BSF发送第一请求,所述第一请求用于请求与BSF绑定的第三网络功能的标识和/或地址信息,然后从BSF接收第三网络功能的标识和/或地址信息。
另一种实施方式中,当借助UDM获取第三网络功能的标识和/或地址信息时,第一网络功能可以向UDM发送第二请求,所述第二请求用于请求当前服务终端的第三网络功能的标识和/或地址信息,然后从UDM接收第三网络功能的标识和/或地址信息。
可选的,上述的第三网络功能可以包括以下至少一项:AMF、SMF。这样在根据AMF/SMF的标识和/或地址信息,获取终端的位置信息时,可以基于触发AMF/SMF的事件订阅,获取终端的位置信息。
一些实施例中,上述终端的位置信息可以包括以下至少一项:数据网接 入标识DNAI、跟踪区标识TAI、小区标识cell ID、终端IP地址、终端IP地址段。
可选的,在确定服务终端和/或第二网络功能的本地网络功能之后,第一网络功能可以执行以下任意一项:
1)当确定的本地网络功能是第一网络功能即自身,比如两者的IP地址一样时,为终端和/或第二网络功能提供服务;
2)当确定的本地网络功能不是第一网络功能即自身,比如两者的IP地址不一样时,重定向会话QoS建立请求到本地网络功能,或者,向第二网络功能发送本地网络功能的地址信息,以便第二网络功能基于此地址信息,重新发起会话QoS建立请求。
请参见图4,图4是本申请实施例提供的另一种服务确定方法的流程图,该方法由第二网络功能执行,该第二网络功能可选为AF等。如图4所示,该方法包括如下步骤:
步骤41:第二网络功能发送第一指示和/或边缘事件。
可选的,第一指示用于指示以下至少一项:
基于终端位置和/或第二网络功能位置,选择服务终端的本地网络功能;
基于终端位置和/或第二网络功能位置,选择服务第二网络功能的本地网络功能;
选择从终端到第二网络功能的路由最佳的本地网络功能;
请求终端的位置信息。
可选的,上述边缘事件可以为:第二网络功能请求网络为其提供边缘服务,网络通过本地网络功能为终端和/或第二网络功能提供边缘服务。
可选的,上述边缘事件可以包括以下至少一项:
边缘QoS监控;
边缘计算服务(edge computing service)。
在本申请实施例中,通过发送第一指示和/或边缘事件,可以使得第一网络功能基于接收的第一指示和/或边缘事件,确定服务终端和/或第二网络功能 的本地网络功能,从而确定提供服务的本地网络功能。
可选的,上述发送第一指示和/或边缘事件可以包括:第二网络功能发送会话QoS建立请求;所述会话QoS建立请求中包括第一指示和/或第一参数;第一参数用于组成网络为第二网络功能提供的边缘事件,或者,第一参数包含在网络为第二网络功能提供的边缘事件中。
可理解的,本实施例中的会话QoS建立请求、第一指示和/或第一参数等内容可以参见上述实施例的说明,在此不再赘述。
下面结合图5对本申请实施例中的服务确定过程进行详细说明。
如图5所示,本申请实施例中的服务确定过程可以包括以下步骤:
步骤501:Local NEF注册到NRF。比如,可以通过信令Nnrf_NFManagement_NFRegister,Local NEF注册到NRF。
步骤502:PDU会话建立以后,BSF绑定PCF、SMF、AMF等网元。
步骤503:AF向NEF即图5中的Initial NEF,触发会话QoS建立请求,如AF session with QoS。
可选的,该会话QoS建立请求中可以包括第一指示或者第一参数。对于第一指示或者第一参数的相关内容可以参见上述实施例,在此不再赘述。
可选的,NEF根据第一指示或者边缘事件,可以执行以下至少一项:
-基于UE位置和/或AF位置选择服务UE的Local NEF,或选择路由最佳的Local NEF;
-请求UE位置。
-将会话QoS建立请求重定向到所选择的Local NEF。
可选的,在收到AF的会话QoS建立请求后,若NEF发现触发该请求的AF与所存储的AF处于相同的位置,其中,该存储的AF先前已向NEF发送了会话QoS建立请求,并根据这个请求找到了一个local NEF,并存储了该local NEF的地址信息,则可以将预先存储的地址信息对应的local NEF直接确定为提供服务的local NEF。则,NEF可以直接跳到步骤514,重定向会话QoS建立请求到local NEF。
步骤504:可选的,NEF收到AF的会话QoS建立请求后,为了寻找local NEF,先查找BSF,并向BSF发送第一请求如Nbsf_Management discovery,以请求与BSF绑定的AMF/SMF的ID和/或IP地址。在本步骤之前,所述BSF已经将AMF,SMF绑定;通过Nbsf_Management_Register,为一个PDU会话,或者一个UE,注册如下信息:AMF ID,AMF IP地址,SMF ID,SMF IP地址。
步骤505:BSF向NEF反馈绑定的AMF/SMF的ID和/或IP地址。
步骤506:可选的,NEF收到AF的会话QoS建立请求后,为了寻找local NEF,向UDM发送第二请求如Nudm_UECM_Get_Request,以请求当前服务UE的AMF/SMF的ID和/或IP地址。
步骤507:UDM向NEF反馈当前服务UE的AMF/SMF的ID和/或IP地址,使用信令:Nudm_UECM_Get_Response。
步骤508:NEF触发SMF的事件订阅,比如NEF通过信令Nsmf_EventExposure_Subscribe触发,其中该信令携带UE IP、DNN、S-NSSAI等信息,以使用UE IP地址等参数信息,获得用户永久标识(Subscription Permanent Identifier,SUPI)、通用公共用户标识(Generic Public Subscription Identifier,GPSI)、DNAI等信息,该DNAI可以用于NEF寻找local NEF,该SUPI和GPSI可以用于NEF向AMF请求UE位置信息。
步骤509:SMF向NEF发送通知消息,比如SMF通过信令Nsmf_EventExposure_Notify发送,其中该信令携带SUPI(Subscription Permanent Identifier)、GPSI(Generic Public Subscription Identifier)、DNAI等信息。
步骤510:NEF触发到AMF的订阅,比如NEF通过信令Namf_EventExposure_Subscribe触发,其中该信令携带UE IP、SUPI、GPSI、DNN、S-NSSAI等信息,以从AMF获取当前UE的位置信息,比如TAI、cell ID等信息。
步骤511:AMF向NEF发送通知消息,比如AMF通过信令 Namf_EventExposure_Notify发送,其中该信令携带UE位置信息,比如TAI、cell ID等信息。
可理解的,基于此步骤510和步骤511,NEF获得了寻找local NEF的必备参数比如TAI、cell ID等信息。
步骤512:NEF根据获得的信息比如TAI、cell ID等,向NRF发起请求比如Nnrf_NFDiscovery_Request,以触发NRF的local NEF查找。
步骤513:NRF向NEF反馈响应比如Nnrf_NFDiscovery_Response,其中包括查找到的local NEF的IP地址或端口号。
步骤514和步骤515:可选的,若NEF检测到自身不是local NEF,比如查找到的local NEF的IP地址与自身的IP地址不一样,则跳转或重定向(Redirect)AF的QoS请求到local NEF,并由local NEF提供服务,比如:将Nnef_AFsessionWithQoS_Create发给local NEF;后续,local NEF向AF反馈会话QoS建立响应比如Nnef_AFsessionWithQoS_Create response。
步骤516和步骤517:可选的,若NEF检测到自身不是local NEF,比如查找到的local NEF的IP地址与自身的IP地址不一样,则向AF反馈会话QoS建立响应比如Nnef_AFsessionWithQoS_Create response,其中包括local NEF的IP地址或端口号,以由AF基于local NEF的IP地址或端口号,向local NEF发起一个全新的会话QoS建立请求。
此外,当NEF检测到自身是local NEF时,NEF直接将会话QoS建立响应发给AF,这种情况就跟NEF同AF交互相同。
