用户设备与两个接入节点建立连接,该用户设备可以称为双连接用户设备,该用户设备的连接类型为双连接;用户设备仅与一个接入节点建立连接,该用户设备可以称为单连接用户设备,该用户设备的连接类型为单连接。
在目前的移动通信网络中,没有识别用户设备的连接类型的技术方案,无法对对用户设备进行接入控制的。
发明内容
本发明实施例所要解决的技术问题在于提供一种对用户设备进行接入控制的方法,网络系统及相关产品,用于识别用户设备的连接类型,为针对性的服务提供支撑。
第一方面,本发明实施例提供了一种对用户设备进行接入控制的方法,该方法包括:
移动管理设备识别用户设备通过接入节点设备接入核心网所采用的连接类型,所述连接类型为单连接或双连接;在所述连接类型为单连接的情况下,所述用户设备通过一个接入节点设备接入所述核心网;在所述连接类型为双连接的情况下,所述用户设备通过两个接入节点设备接入所述核心网;
所述移动管理设备依据所述用户设备的连接类型,对所述用户设备进行接入控制。
在本实施例可以应用于非独立组网或者独立组网的移动通信网络;其中,接入节点设备可以称为接入节点,例如第四代(4G)网络或第五代(5G)网络中的基站;同一个用户设备可以接入两个基站,如主接入节点和辅接入节点。移动管理设备可以为移动管理实体(mobility management entity,MME)或接入和移动性管理功能(access and mobility management function,AMF)设备。
在本实施例中,移动管理设备对用户设备进行接入控制可以是移动管理设备按照连接类型,在确定用户设备有双连接能力或者签约了双连接,当前该用户设备如果使用单连接,则对其进行接入控制,使该用户设备不能使用业务数据;或者,对单连接用户设备或者多 连接用户设备分别进行不同的许可控制。具体过程本发明实施例不作唯一性限定。
由于一个用户设备会对应一个移动管理设备,可能对应多个网关设备或其网络设备,因此本实施例通过移动管理设备识别用户设备的连接类型,可以将识别功能聚集在一个固定的设备中;另外,移动管理设备是用户设备经接接入节点设备首先接入的核心网设备,因此如果在移动管理设备进行接入控制等针对性服务,相比于由其他设备识别后再通知移动管理设备更为及时,延迟更小。
在一个可能的实现方式中,所述移动管理设备识别用户设备通过接入节点设备接入核心网所采用的连接类型包括:
所述移动管理设备接收接入节点设备发送的所述用户设备的接入类型参数,所述接入类型参数用于指示所述用户设备的无线接入类型或所述接入节点设备的类型;所述移动管理设备根据所述接入类型参数确定所述用户设备的连接类型;
或者,所述移动管理设备根据所述用户设备的双连接能力、所述用户设备的签约信息以及所述移动管理设备的本地配置中的一项或多项,确定所述用户设备的连接类型;

在本实施例中提供了多种可选方法,由移动管理设备确定用户设备的连接类型。
第一种方法主要由接入节点设备通过消息发送接入类型参数给移动管理设备,移动管理设备根据接入类型参数来确定用户设备的连接类型。其中,携带该接入类型参数的消息可以是在建立、更新、删除与上述用户设备相关的承载的流程中所使用的消息中,例如:无线接入承载的更新请求消息等,也可以使用专用的消息来携带该接入类型参数,本实施例对此不作唯一性限定。另外,该接入类型参数指示用户设备的无线接入类型或者接入节点设备的类型的具体手段,可以是直接指示,也可以是移动管理设备所能识别的参数通过判断得出,具体形式本发明实施例不作唯一性限定。该第一种方法,移动管理设备可以从携带的信息中直接获得用户设备的连接类型,效率较高。
第二种方法主要由移动管理设备获得确定连接类型所需的参数,然后据此确定用户设备的连接类型。其中,用户设备的双连接能力可以由用户设备进行网络注册时上报;用户的签约信息中也可以携带该用户设备是否允许使用双连接的信息,移动管理设备可以从保存有签约信息的设备例如归属用户服务器中获得;移动管理设备的本地配置也可以包含是否允许该用户设备使用双连接的信息;移动管理设备可以根据用户设备的双连接能力、用户的签约信息、本地配置等其中的一项或者多项确定连接类型。该第二种方法,移动管理设备可以相对于前述第一种方法间接获得较为准确的用户设备的连接类型,可以进一步减少信令的使用以及数据的传递。
第三种方法主要由单连接或双连接对数据使用报告的影响来确定;第四种则是通过IP地址来区分不同的接入节点设备的类型,例如第一基站或第二基站,其中第一基站可 以为4G基站,第二基站可以为5G基站,或者第一基站和第二基站可以都为5G基站;据此来确定用户设备的连接类型。在基于4G核心网的非独立组网的场景下,双连接的用户设备接入第一基站和第二基站分别为4G基站和5G基站,在基于5G核心网的组网场景下,双连接的用户设备接入第一基站和第二基站都为5G基站。该第三种方法,提供了由移动管理设备智能化的识别用户设备的连接类型的实现手段,不必依赖于已经存在或传递的用于识别用户设备的连接类型的数据。
在一个可能的实现方式中,主接入节点(或称为第一接入节点、主接入节点设备)、eNodeB以及4G基站统称为第一基站;辅接入节点(或第二接入节点、辅接入节点设备)、下一代基站(next generation NodeB,gNB),演进型基站(evolved NodeB,eNB)以及5G基站统称为第二基站。

所述移动管理设备获取所述移动管理设备的本地配置,在所述本地配置中包含是否允许所述用户设备建立双连接的信息;依据所述本地配置确定所述用户设备的连接类型。
在本实施例中,如果用户设备有双连接能力,则可以确定该用户设备的连接类型为双连接,否则为单连接;签约信息中如果包含用户设备具有双连接能力的信息,则可以确定该用户设备的连接类型为双连接,否则为单连接;上述本地配置如果允许用户设备采用双连接,则确定该用户设备的连接类型为双连接,否则为单连接;也可以综合以上三个因素,全部为是则确定为双连接,否则为单连接,或者其中一个为是则确定为双连接,否则为单连接,或者全部为是则确定为双连接,全部为否则确定为单连接,其他情况确定无法确定连接类型。
在一个可能的实现方式中,所述移动管理设备根据接收所述接入节点设备发送的数据使用报告,所述数据使用报告中包含用户设备的流量信息,所述移动管理设备根据所述数据使用报告确定所述用户设备的连接类型包括:
所述移动管理设备确定在所述用户设备的连接态周期内,接收到所述接入节点设备发送的数据使用报告,则确定所述用户设备的连接类型为双连接。
另一方面,如果所述移动管理设备确定在所述用户设备的连接态周期内,没有接收到所述接入节点设备发送的数据使用报告,则确定所述用户设备的连接类型为单连接。
本实施例通过连接态周期内是否收到接入节点设备发送的数据使用报告来确定用户设备的连接类型,不必为了确定用户设备的连接类型而额外消耗信令。
在一个可能的实现方式中,所述移动管理设备根据接收的接入节点设备的IP地址,确定所述用户设备的连接类型包括:
所述移动管理设备根据接收的接入节点设备的IP地址,将接入节点设备区分为第一基站或第二基站;
在所述用户设备接入的接入节点设备包含第一基站和第二基站时,所述移动管理设备确定所述用户设备的连接类型为双连接;

在本实施例中,移动管理设备可以根据IP地址来确定接入节点设备的类型是第一基站还是第二基站,随后再依据用户设备接入到何种类型的接入节点设备来确定连接类型。该IP地址可以是按照已有流程上报给移动管理设备的,因此不必消耗额外的信令,节省了信令开销。
在一个可能的实现方式中,所述移动管理设备根据接收的接入节点设备的IP地址,将接入节点设备区分为第一基站或第二基站,包括:
在所述用户设备不被允许建立双连接的情况下,所述移动管理设备在接收到所述接入节点设备的IP地址后,将所述接入节点设备的IP地址对应的接入节点设备标记为第一基站;
所述移动管理设备在业务数据包的转发通道建立到第一基站的流程中接收接入节点设备的IP地址,将所述接入节点设备的IP地址对应的接入节点设备标记为第一基站;
所述移动管理设备在所述用户设备接入两个IP地址,且其中一个IP地址对应的接入 节点设备为第一基站时,将所述两个IP地址中的另一IP地址对应的接入节点设备标记为第二基站。
本实施例在移动管理设备一侧,通过对收到的IP地址的分析标记了接入节点所属的基站类型,可以准确识别出不同类型的基站。
在一个可能的实现方式中,所述业务数据包的转发通道建立到第一基站的流程包括:
注册流程、跟踪区域更新、服务请求流程以及附着流程中的任意一项。
本实施例提供了如何标记接入节点设备的类型的具体实现手段。其中,用于用户设备不被允许建立双连接的情况,可以是移动管理设备的本地配置上述用户设备不具有双连接能力,或者其他原因导致其不能建立双连接的情况;由于特定流程中,如跟踪区域更新、服务请求流程以及附着流程等,主接入节点通常将承载的业务数据包的转发通道先建立到主接入节点上,即发送给移动管理设备的接入节点的IP地址和隧道端点标识(tunnel endpoint identifier,TEID)通常为主接入节点分配的,因此可以标记为第一基站;由于双连接的场景下,通常是一个第一基站,另一个为第二基站,因此在确定其中一个为第一基站的情况下,另一个为第二基站。本实施例可以在不增加网络开销的情况下,准确标记不同类型的基站,为识别用户设备的连接类型提供依据。
在一个可能的实现方式中,所述方法还包括:
所述移动管理设备在标记IP地址对应的接入节点设备为第一基站或第二基站后的预定时间之后,删除标记的IP地址对应的接入节点设备为第一基站或第二基站的信息。
在本实施例中,设置的预定时间为老化时间,可以使用老化定时器来实现计时,在某一个IP地址被标记后,定时器超时则删掉该IP地址的标记,可以确保标记的准确性。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
如图1A-图1E,为5种混合组网架构的示意图,这些混合组网架构混合了4G接入网和5G接入网。其中,图1A-图1C、1E所述的架构可以称为非独立组网架构。
在上述混合组网架构中,用户设备同时与两个接入节点设备(后面简称接入节点或节点设备)建立连接,分别为接入节点1和接入节点2;用户设备的业务数据可以通过这两个接入节点中的任意一个或两个进行转发。在非独立组网架构中,用户设备也可以仅与一个接入节点建立连接。
其中,在图1A的模式下(option 3模式),网络侧的服务网关将业务数据包发送给接入节点1,由接入节点1根据用户设备的双连接能力,以及网络状态等将部分业务数据包分流到接入节点2转发给用户设备。在本发明实施例中业务数据使用数据包形式转发,因此可以将业务数据称为业务数据包,后续实施例中不再一一说明。在图1A、图1B以及图1C中所示的服务网关属于网关设备的一种,在后续实施例中还会提到其他的网关设备,例如:数据网关、SMF设备、UPF设备等。
在图1B的模式下(option 3a模式),业务数据包在服务网关处分流到接入节点1和接入节点2,再由接入节点1和接入节点2分别将接收到的业务数据包转发给用户设备。
在图1C的模式下(option 3x模式),网络侧将业务数据包发送给接入节点2,接入节点2可将部分业务数据包分流到接入节点1,接入节点1将收到的业务数据包转发给用户设备,接入节点2将未分流到接入节点1的业务数据包转发给用户设备。
在图1A、图1B以及图1C所示的非独立组网架构中,将和移动管理设备有信令接口的接入节点1称为主接入节点、第一接入节点或主接入节点设备,将和移动管理设备没有信令接口的接入节点2称为辅接入节点、第二接入节点或辅接入节点设备。
图1A、图1B以及图1C所示的非独立组网架构的示意图,可以应用在演进的分组系统(evolved packet system,EPS)网络。接入节点1和接入节点2是用户设备接入到核心网的节点,其中,主接入节点可以是基站(例如NodeB),辅接入节点可以是演进型基站(evolved NodeB,eNB)、5G移动通信系统中的下一代基站(next generation NodeB,gNB)或未来移动通信系统中的基站等。移动管理设备可以是MME,服务网关可以是服务网关(serving gateway,S-GW),数据网关可以是分组数据网络网关(packet data network gateway,PDN-GW)。
在图1D所示的组网架构图中,接入节点1和接入节点2连接到5G核心网(5G Core,5GC)中,用户设备可以同时连接接入节点1和接入节点2。其中,接入节点1可以为支 持演进LTE(evolved LTE,eLTE)接入的eNB,接入节点2可以为支持NR接入的gNB。控制面的信令通过gNB传输给5GC,即信令锚定点在gNB。上述组网架构可以对应于option4组网方式。此外,eNB也可以不通过gNB,而直接与5GC连接,这种情况下对应于option 4a组网方式。
在图1E所示的组网架构图中,接入节点1和接入节点2连接到5G核心网(5G Core,5GC)中,用户设备可以同时连接接入节点1和接入节点2。其中,接入节点1可以为支持演进LTE(evolved LTE,eLTE)接入的eNB,接入节点2可以为支持NR接入的gNB。控制面的信令通过eNB传输给5GC,即信令锚定点在eNB。上述组网架构可以对应于option7组网方式。gNB也可以不通过eNB,而直接与5GC连接,这种情况下对应于option7a/7x组网方式。
图1A-图1E所示的组网架构的示意图,可以应用到5G网络;如图2所示的5G网络架构示意图,包括:用户设备、无线网络和5G核心网;用户设备通过当前位置的接入节点接入无线网络,核心网设备用于用户设备的注册、安全认证、移动性管理、位置管理、会话管理和转发用户设备和外部数据网络之间的数据包等。
其中,图2中无线网络包含的设备可以为新空口(new radio,NR)设备;核心网设备包含会话管理功能(session management function,SMF)设备,AMF设备,用户面功能(user plane function,UPF)设备,统一数据管理(unified data management,UDM)设备,策略控制功能(policy control function,PCF)设备,鉴权服务功能(authentication server function,AUSF)设备,网络切片选择功能(network slice selection function,NSSF)设备,网络公开功能(network exposure function,NEF)设备,网络仓库功能(network repository function,NRF)设备和应用功能(application function,AF)设备等,本申请实施例对此不作具体限定。
其中,NR设备可以对应到图1A至图1C中的接入节点,接入和移动性管理功能AMF可以对应到图1A-图1C中的移动管理设备。另外,在图2中所示的N1、N2、N3、N4、N9、N6、Nnssf、Nnef、Nnrf、Nnpcf、Nudm、Naf、Nausf、Namf以及Nsmf均为服务化接口,在此不再赘述。
在图1D-图1E所示的组网场景下,双连接的用户设备与两个接入节点建立连接,此时用户设备连接两个5G基站,也即:主接入节点和辅接入节点均为5G基站。针对图2所示的5G网络架构,主接入节点可以是eNB,辅接入节点可以是gNB,或者主接入节点可以是下一代基站gNB,辅接入节点可以是演进型基站eNB。
如图1A-图1E以及图2所示网络架构,本发明实施例提供了识别用户设备的接入类型的方法,在识别用户设备的接入类型后可以执行接入控制,具体可以包括:移动管理设备识别用户设备通过接入节点设备接入核心网所采用的连接类型,所述连接类型为单连接或双连接;在所述连接类型为单连接的情况下,所述用户设备通过1个接入节点设备接入所述核心网;在所述连接类型为双连接的情况下,所述用户设备通过两个接入节点设备接入所述核心网;
所述移动管理设备依据所述用户设备的连接类型,对所述用户设备进行接入控制。后续实施例中,将分别就不同的网络架构下,移动管理设备识别用户设备的连接类型的方法, 以及识别后的使用进行举例说明。其中,识别后的使用可以包括对用户设备进行接入限制、计费策略,服务质量控制策略和许可(license)控制等。
移动管理设备识别用户设备的连接类型的第一类方法举例:
主接入节点主动通知移动管理设备用户设备的接入类型,该接入类型可以为接入节点类型或者无线接入类型等,移动管理设备根据该接入类型获知用户设备的业务数据包经过主接入节点还是辅接入节点转发,由此获知所述用户设备属于单连接用户设备或双连接用户设备。
下面给出具体的实施例来描述本申请中移动管理设备确定用户的连接类型的方案。以用户设备接入4G核心网EPS为例,结合图2所示的5G网络,本实施例可以适用于图1A-图1C的组网架构。
在本实施例的非独立组网架构中,用户设备双连接的建立由主接入节点决策,对于双连接用户设备而言,主接入节点可能触发辅接入节点的添加、更新以及删除等流程,这些流程用于建立、更新以及删除通过辅接入节点的业务数据包的转发通道。
例如:
当主接入节点决定将用户设备的某个承载的业务数据包由辅接入节点转发时,主接入节点触发辅接入节点添加流程,为用户设备建立双连接;或者,
当用户设备已经建立了双连接,主接入节点决定将用户设备的某个承载的业务数据包由主接入节点改为辅接入节点转发时,主接入节点触发辅接入节点的更新流程,将该承载切换到辅接入节点;或者,
当用户设备已经建立了双连接,主接入节点决定将用户设备的由辅接入节点转发的业务数据包改为由主接入节点转发时,主接入节点触发辅接入节点删除流程。
在以上三种流程中,由于涉及到承载的业务数据包由主接入节点转发改为由辅接入节点转发,或者由辅接入节点转发改为由主接入节点,主接入节点可以通知网络侧主接入节点或者辅接入节点的用于接收业务数据包的IP地址和TEID,基于此本发明实施例流程可以具体为:
301:主接入节点发送演进通用陆地无线接入网无线接入承载(evolved universal terrestrial radio access network radio access bearer,E-RAB)更新指示消息给移动管理设备,该E-RAB更新指示消息中携带主接入节点或辅接入节点的IP地址和TEID,用于通知网络修改下行数据包的转发通道。
其中,该E-RAB更新指示消息中还可以携带接入类型参数,该接入类型参数可以为接入节点类型,如NodeB,eNB或gNB等,所述接入类型参数也可以为无线接入类型,如演进通用陆地无线接入(evolved universal terrestrial radio access,E-UTRA)或者NR等。其中,转发业务数据包的接入节点类型为NodeB或者eNB时,对应的无线接入类型为E-UTRA。转发业务数据包的接入节点类型为gNB时,对应的无线接入类型为NR。
移动管理设备收到上述无线接入承载更新请求消息后,根据其中携带的接入类型参数和当前的组网模式,获知这个承载对应的业务数据包由主接入节点还是辅接入节点转发。
更具体地,如果接入类型参数为eNB或gNB或NR,则移动管理设备获知转发业务数 据包的接入节点为辅接入节点。如果接入类型参数为NodeB或E-UTRA,则移动管理设备获知转发业务数据包的接入节点为主接入节点。如果用户设备有任意一个承载对应的业务数据包由辅接入节点转发,则移动管理设备确定用户设备为双连接用户设备;如果用户设备所有承载对应的业务数据包都由主接入节点转发,则移动管理设备确定上述用户设备为单连接用户设备。
移动管理设备基于用户设备是双连接用户设备或单连接用户设备的信息,可以进行对用户设备的接入控制,具体的接入控制例如:
移动管理设备基于用户设备的双连接能力,以及签约数据中的双连接能力,对有双连接能力但是当前为单连接的用户进行接入控制,用户设备将不能正常使用数据业务;或者,
对单连接用户设备或双连接用户设备分别进行License控制,即区分统计单连接用户设备数,和双连接用户设备数,当单连接用户设备数或者双连接用户设备数超过License购买的值时,移动管理设备进行告警或者限制新的用户设备接入。
302:移动管理设备发送更新承载请求(modify bearer request)消息给服务网关,在该更新承载请求消息中携带主接入节点或辅接入节点的IP地址和TEID,所述无线接入承载更新请求消息中还携带上述接入类型参数。
服务网关在接收到上述更新承载请求消息后,存储其中携带的接入节点的IP地址和TEID。后续所述承载对应的业务数据包,服务网关将发送给上述IP地址和TEID对应的接入节点。
服务网关可以参考移动管理设备根据接入类型参数确定用户设备为单连接用户设备或双连接用户设备的方式,在此不再赘述。
服务网关基于用户设备为单连接用户设备或双连接用户设备的信息,可以对单连接用户设备或者双连接用户设备进行区分计费。甚至对于同一用户设备,可以对于主接入节点转发的业务数据包,和对于辅接入节点转发的业务数据包,进行区分计费。例如,辅接入节点转发的业务数据包的费率低于通过主接入节点转发的业务数据包的费率。
进一步地,服务网关可以将上述承载对应的接入类型参数发送给数据网关,数据网关可以将用户设备的连接类型通知给策略控制功能,以便对单连接用户设备或者双连接用户设备进行不同的服务质量控制或者计费控制。
303:服务网关回复更新承载响应(modify bearer response)消息给移动管理设备,用于通知所述承载的下行通道更新完成。
304:移动管理设备回复E-RAB更新指示确认(E-RAB modification indication confirm)给主接入节点,通知所述承载的下行通道更新完成。
后面的双连接切换流程简单补充一下,便于方案的完整。
以上流程以主接入节点执行建立、更新以及删除通过辅接入节点传输业务数据包的转发通道的流程为例,使用E-RAB更新指示消息携带接入类型参数给移动管理设备;另外,主接入节点还可以在其他流程使用其他消息将接入类型参数发送给移动管理设备,例如:在终端进行X2切换流程中,主接入节点采用通道切换请求消息通知主接入节点/辅接入节点的IP地址和TEID,在该通道切换请求消息中携带上述接入类型参数,使得移动管理设备及网络中的其他设备可以根据接入类型参数来确定用户设备为单连接用户设备或者双 连接用户设备。
以用户设备接入5G核心网为例,如图4所示,本实施例可以适用于图1D和图1E的组网架构,请一并参考图2所示的5G网络架构。
本实施例中,主接入节点以服务质量流(quality of service flow,QoS Flow)的粒度来分流业务数据包,主接入节点将服务质量流(简称业务流)对应的主接入节点或辅接入节点的IP地址和TEID通知给AMF或SMF,以便AMF或SMF确定用户设备的连接类型,并根据连接类型对用户设备进行不同的策略控制。
在本实施例的非独立组网架构中,用户设备的双连接的建立由主接入节点决策,对于双连接用户设备,主接入节点可能触发辅接入节点添加、更新以及删除等流程,用于建立、更新以及删除通过辅接入节点的业务数据包的转发通道。
例如:
当主接入节点决定将用户设备的某个业务流(QoS Flow)的业务数据包由辅接入节点转发时,主接入节点触发辅接入节点添加流程,为用户设备建立双连接;或者,
当用户设备已经建立了双连接,主接入节点决定将用户设备的某个业务流的业务数据包改由辅接入节点转发时,主接入节点触发辅接入节点的更新流程,将该业务流切换到辅接入节点;或者,
当用户设备已经建立了双连接,主接入节点决定将由辅接入节点转发的用户设备的业务数据包改为由主接入节点转发时,主接入节点触发辅接入节点的删除流程。
在以上三种流程中,因为涉及到业务流的业务数据包由主接入节点转发改为由辅接入节点转发,或者由辅接入节点转发改为由主接入节点转发,主接入节点需要通知网络侧主接入节点或者辅接入节点的连接信息(例如用于接收业务数据包IP地址和TEID),基于此本发明实施例流程可以具体为:
401:主接入节点发送PDU会话资源更新指示(session resource update indication)消息给接入和移动性管理功能,该PDU会话资源更新指示消息中携带主接入节点或辅接入节点的IP地址和TEID,用于通知接入和移动性管理功能修改下行数据包的转发通道。
其中,该PDU会话资源更新指示消息中还携带接入类型参数,该接入类型参数可以为接入节点类型,如eNB或gNB等,所述接入类型参数也可以为无线连接类型,如E-UTRA或者NR等。转发业务数据包的接入节点为eNB时,无线连接类型为E-UTRA,转发业务数据包的接入节点为gNB时,无线连接类型为NR。
接入和移动性管理功能收到PDU会话资源更新指示消息后,根据接入类型参数和组网模式,获知上述业务流的业务数据包由主接入节点还是辅接入节点转发。如果用户设备有任意一个业务流的业务数据包由辅接入节点转发,则接入和移动性管理功能确定该用户设备为双连接用户设备;如果用户设备所有业务流的业务数据包都由主接入节点转发,则接入和移动性管理功能确定该用户设备为单连接用户设备。
接入和移动性管理功能可以基于上述用户设备是单连接用户设备或双连接用户设备的信息,对上述用户设备进行接入控制,如:
基于用户设备的双连接能力,签约数据中的双连接能力,对有双连接能力但是当前为 单连接的用户设备进行接入控制,使该用户设备将不能正常使用数据业务;或者,
对单连接用户设备或双连接用户设备分别进行License控制,即区分统计单连接用户设备数和双连接用户设备数,当单连接用户设备数或者双连接用户设备数超过License购买的值时,移动管理设备进行告警或者限制新的用户设备接入。
402:接入和移动性管理功能发送PDU会话上下文更新请求(PDU session updatecontextrequest)消息给会话管理功能。
其中,该PDU会话上下文更新请求消息中携带主接入节点或辅接入节点的IP地址和TEID,所述PDU会话上下文更新请求消息中还携带接入类型参数。该PDU会话上下文更新请求可以通过Nsmf接口发送。
会话管理功能可以参考接入和移动性管理功能根据接入类型参数确定用户设备是单连接用户设备或双连接用户设备的方式,在此不再赘述。
会话管理功能基于上述用户设备是单连接用户设备或双连接用户设备的信息,可以对单连接用户设备或者双连接用户设备进行区分的计费或者服务质量控制,甚至对于同一用户设备,可以对于主接入节点转发的业务数据包,和对于辅接入节点转发的业务数据包,进行区分计费或者服务质量控制。
进一步,会话管理功能可以将上述业务流对应的接入类型参数通知给策略控制功能,以便策略控制功能对单连接用户设备或者双连接用户设备进行不同的服务质量控制或者计费控制等。
403:会话管理功能发送N4会话更新请求(session modification request)消息给用户面功能,该N4会话更新请求消息中携带主接入节点或辅接入节点的IP地址和TEID,该N4会话更新请求消息中还携带接入类型参数,以便用户面功能对单连接用户设备或者双连接用户设备进行不同的服务质量控制或者计费控制。
用户面功能存储上述N4会话更新请求消息中携带的IP地址和TEID,后续上述用户设备的业务流的业务数据包,用户面功能将发送给上述IP地址和TEID对应的接入节点。
404:用户面功能回复N4PDU会话更新响应(session modification response)消息给会话管理功能。该PDU会话更新响应可以在Nsmf接口发送。
405:会话管理功能回复PDU会话上下文更新响应(PDU session update context response)消息给接入和移动性管理功能,用于通知上述业务流的下行通道更新完成。
406:接入和移动性管理功能回复PDU会话资源更新确认(PDU session resource update acknowledge)消息给上述主接入节点,通知上述业务流的下行通道更新完成。
以上流程以主接入节点执行建立、更新以及删除通过辅接入节点的业务数据包的转发通道的流程为例,使用PDU会话资源更新指示消息携带接入类型参数给接入和移动性管理功能;另外,主接入节点还可以在UE进行X2切换流程中,采用通道切换请求消息通知主接入节点/辅接入节点的IP地址和TEID时,在该通道切换请求消息中携带接入类型参数,使得接入和移动性管理功能及网络中的其他设备据此确定用户设备为单连接用户设备或者双连接用户设备。
以上给出了移动管理设备根据接入类型参数来识别用户设备的连接类型的方案,下面 再给出移动管理设备识别用户设备的连接类型的另一种方案。在该方案中,核心网的设备,例如移动管理设备(MME或AMF)可以通过自学习获知用户设备为单连接用户设备或双连接用户设备。
以用户设备通过无线接入网接入EPS核心网为例,如图5所示,其中,归属用户服务器(home subscriber server,HSS)负责用户签约信息的管理和维护。归属用户服务器也可以融合UDM的功能。
501:用户设备开机,发起附着流程,发送附着请求消息给移动管理设备,该附着请求消息经过主接入节点转发给移动管理设备。
其中,所述附着请求消息中携带上述用户设备的双连接能力的信息,如用户设备支持与新空口的双连接(dual connectivity with NR)能力。
502:移动管理设备向上述用户设备的HSS发送签约数据获取请求。
503:移动管理设备接收上述HSS返回的签约数据获取响应,在该签约数据获取响应中包含上述用户设备的签约数据,该签约数据中包含用户设备的双连接能力的信息。
例如:签约数据中包括新空口辅助无线接入类型(NR as secondary radio access type,NR as secondary RAT)能力。
其中,移动管理设备通过自学习识别用户设备的连接类型可以通过如下方式:

此外,移动管理设备还可以结合本地配置识别用户设备,例如将本地配置允许建立双连接的用户设备识别为双连接用户设备。将本地配置不允许建立双连接的用户设备识别为单连接用户设备。
移动管理设备基于识别的双连接用户设备或单连接用户设备的信息,可以对用户设备进行接入控制,如:

510:服务网关回复更新承载响应(modify bearer response)消息给移动管理设备,用于通知上述承载的下行通道更新完成。
以上实施例以附着流程为例进行了介绍,UE在进行跟踪区域更新时,核心网中的设备也可以识别用户设备的连接类型。此时,UE在跟踪区更新请求消息中携带上述双连接能力指示,移动管理设备接收到跟踪区更新请求消息后,采用上面类似的自学习方法识别用户设备的连接类型。随后,移动管理设备还可以发送建立会话请求消息给服务网关,其中携带用户设备的双连接能力指示。移动管理设备、服务网关和数据网关的处理流程和附着流程类似,本实施例不再赘述。
仍以用户设备通过无线接入网接入EPS核心网为例,如图6所示,本实施例的非独立组网架构下,主接入节点可以触发双连接用户设备的流量上报流程,将通过辅接入节点转发的承载以及对应的转发流量信息通知给包括移动管理设备在内的核心网设备。
601,主接入节点发送用户设备的流量使用报告(secondary rat usage data report)消息给移动管理设备,该流量使用报告消息中携带承载标识,以及对应的流量信息。
如果流量使用报告中包含辅接入节点转发的流量信息,则移动管理设备根据确定该用户设备为双连接用户设备。如果流量使用报告中只有主接入节点转发的流量信息,则移动管理设备根据确定该用户设备为单连接用户设备。其中,用户设备的流量信息包括用户设备的上下行数据包的流量信息。
移动管理设备可以对该用户设备进行接入控制,如:
基于用户的双连接能力,签约数据中的双连接能力,对有双连接能力但是当前为单连接的用户进行接入控制,用户设备将不能正常使用数据业务;
对单连接用户设备或双连接用户设备分别进行License控制,即区分统计单连接用户设备数,和双连接用户设备数,当单连接用户设备数或者双连接用户设备数超过License购买的值时,移动管理设备进行告警或者限制新的用户设备接入。
602:移动管理设备发送流量上报通知消息给服务网关。
服务网关可以参考移动管理设备依据流量上报通知消息确定上述用户设备属于单连接用户设备或双连接用户设备的方式。
服务网关基于上述用户设备属于单连接用户设备或双连接用的信息,可以对单连接用户设备或者双连接用户设备进行区分计费;对于同一用户设备,还可以对主接入节点转发的业务数据包,和辅接入节点转发的业务数据包,进行区分计费。
603:服务网关发送上述流量上报通知消息给数据网关。

604:数据网关回复改变通知确认(change notification ACK)消息;
605:服务网关回复改变通知确认消息。
在本实施例中,上述流量上报通知消息可以通过专有流程上报,也可以在当前流程的信令消息中上报,并不影响本实施例的实现,在此不再赘述。上述当前流程可以是:切换,注册更新,服务请求,PDU会话更新/删除,跟踪区域更新,专有承载更新/删除等流程。
另外,移动管理设备在用户设备的连接态周期内收到主接入节点上报的流量使用报告,则移动管理设备在S1释放(release)流程后仍然将上述用户设备标记为双连接用户设备。如果移动管理设备在连接态周期内没有收到主接入节点上报的流量使用报告,则S1release流程后将所述用户设备标记为单连接用户设备。本实施例,在已经获知用户设备的连接类型后,可以通过主接入节点在连接态周期内是否有上报流量使用报告来确定用户的连接类型,不用额外消耗信令,也不用传递额外的数据,节省了网络的资源。
以用户设备接入5G核心网为例,如图7所示,在本实施例,主接入节点可以触发双连接用户设备的流量上报流程,主接入节点将通过辅接入节点转发的业务流以及流量上报通知给包括接入和移动性管理功能在内的核心网设备。
701:主接入节点发送流量使用报告(secondary rat usage data report)消息给接入和移动性管理功能,所述流量上报通知消息中携带业务流标识(QoS flowID,QFI),以及对应的流量信息。
接入和移动性管理功能根据上述流量上报通知消息,确定该用户设备为双连接用户设备,可以对用户设备进行接入控制,如:
对单连接用户设备或双连接用户设备分别进行License控制,即区分统计单连接用户设备数,和双连接用户设备数,当单连接用户设备数或者双连接用户设备数超过License购买的值时,接入和移动性管理功能进行告警或者限制新的用户设备接入。
702:接入和移动性管理功能发送PDU会话上下文更新请求(PDU session_updatecontextrequest)给会话管理功能,上述流量上报通知消息中携带701 中获得的业务流标识,及其对应的流量信息。
其中,该PDU更新会话管理上下文请求使用Nsmf接口发送。
会话管理功能可以参考接入和移动性管理功能依据流量上报通知消息确定用户设备属于单连接用户设备或双连接用户设备的方式,在此不再赘述。
会话管理功能基于上述用户设备为单连接用户设备或双连接用户设备的信息,可以对单连接用户设备或者双连接用户设备进行区分的计费和服务质量控制;另外,针对同一用户设备,可以对于主接入节点转发的业务数据包,和对于辅接入节点转发的业务数据包,进行区分计费和服务质量控制。
703:会话管理设备PDU会话上下文更新响应(PDU session_update context response)。
其中,该PDU更新会话管理上下文响应可以使用Nsmf接口发送。
在本实施例中,上述流量上报可以通过列举的专有流程上报,也可以在当前流程的信令消息中上报,并不影响本实施例的实现,在此不再赘述。上述专有流程是指专门下发change notification request的流程;上述当前流程可以是:切换,注册更新,服务请求,PDU会话更新/删除,跟踪区域更新,专有承载更新/删除等流程。
另外,接入和移动性管理功能在用户设备的连接态周期内收到主接入节点上报的Secondary RAT Usage Data Report,则接入和移动性管理功能在N2释放(release)流程后将上述用户设备标记为双连接用户设备。如果接入和移动性管理功能在连接态周期内没有收到主接入节点上报的Secondary RAT Usage Data Report,则N2 Release流程后将上述用户设备标记为单连接用户设备。
本发明实施例还提供了网络侧设备自学习标记接入节点类型,并据此确定用户设备的连接类型的方法,具体如下:
一、以EPS为例:
在以上图3和图5所示的流程中,主接入节点在发送为承载分配的IP地址和TEID给移动管理设备后,移动管理设备转发给服务网关。移动管理设备可以首先对IP地址对应的接入节点进行标记,具体如下:
1、移动管理设备在确认是否可以允许用户设备使用双连接后,对于不允许使用双连接的用户设备,即单连接用户设备,移动管理设备收到的接入节点的IP地址和TEID应当是主接入节点分配的,因此移动管理设备可以将此IP地址对应的接入节点标记为主接入节点或第一基站。
2、移动管理设备在确认允许用户设备使用双连接,在前文举例的跟踪区域更新、服务请求流程以及附着等特定流程中,主接入节点将承载的业务数据包的转发通道先建立到主接入节点上,即发送给移动管理设备的接入节点的IP地址和TEID应当为主接入节点分配的。因此移动管理设备在这些特定流程中,收到接入节点的IP地址和TEID后,则将收到的IP地址对应的接入节点标记为第一基站;或者更具体地标记为:4G基站,eNodeB,主接入节点或者第一接入节点。即,移动管理设备收到接入节点发送的初始上下文响应消息,获取消息中携带的接入节点的IP地址和TEID后,将此将此IP地址对应的接入节点标记为第一基站。
3、移动管理设备在确认用户设备的连接类型为双连接用户设备后,收到新的接入节点的IP地址则可以标记为第二基站,或者更具体地标记为:5G基站,gNB或者,eNB,或者辅接入节点。或者,如果移动管理设备收到多个接入节点的IP地址,则将同一个用户设备的,不同于标记为第一基站的用户面IP地址对应的接入节点标记为第二基站。
例如:图3所示,由于E-RAB指示消息是为双连接用户设备发送的,移动管理设备收到E-RAB更新指示消息后,在该E-RAB更新指示消息中携带接入节点的IP地址和TEID。由于已经有被标记为第一基站的IP地址,而当前E-RAB更新指示消息中携带的接入节点的IP地址不同于上述已经标记的第一基站的IP地址,因此移动管理设备将新收到的E-RAB更新指示消息中的IP地址对应的接入节点标记为第二基站。
进一步的,移动管理设备通过以上3个方法标记了基站类型,该移动管理设备可以为此设置老化定时器,老化定时器超时后,将标记的基站类型清空,重新执行本实施例的学习过程。
基于上述的自学习过程,移动管理设备可以获知用户设备建立的承载,哪些是建立在主接入节点上,哪些是建立在辅接入节点上。据此,移动管理设备可以识别用户设备的连接类型,具体为:当用户设备有任意一个承载建立在辅接入节点时,移动管理设备确定该用户设备为双连接用户设备;当用户设备所有承载都建立在主接入节点时,移动管理设备确定该用户设备为单连接用户设备。
进一步的,移动管理设备在通过自学习识别用户设备的接入点类型得到识别结果后,可以将该识别结果通知给服务网关、数据网关以及策略控制功能等设备,比如将识别的接入点类型发给服务网关、数据网关以及策略控制功能。又比如,通过信令消息将用户设备为单连接用户设备或者双连接用户设备的信息通知给服务网关、数据网关以及策略控制功能等设备。
二、以5G核心网为例:
在以上图4所示的流程中,主接入节点在发送为承载分配的IP地址和TEID给接入和移动性管理功能后,接入和移动性管理功能转发给会话管理功能,会话管理功能转发给用户面功能。接入和移动性管理功能可以首先对IP地址对应的接入节点进行标记,具体如下:
1、在注册流程以及服务请求流程等特定流程中,主接入节点将业务流相关的业务数据包的转发通道先建立到本地,因此发送给接入和移动性管理功能的接入节点的IP地址和TEID是主接入节点分配的。因此,接入和移动性管理功能在上述特定流程中,收到接入节点的IP地址和TEID后,则将收到的IP地址对应的接入节点标记为第一基站。
例如:接入和移动性管理功能收到接入节点发送的初始上下文响应消息,获取消息中携带的接入节点的IP地址和TEID后,将该IP地址对应的接入节点标记为第一基站。
2、接入和移动性管理功能在确认用户设备的连接类型为双连接用户设备后,收到新的接入节点的IP地址则可以标记为第二基站;或者,如果接入和移动性管理功能收到多个接入节点的IP地址,则将同一个用户设备的,不同于标记为第一基站的用户面IP地址对应的接入节点标记为第二基站。
例如:在图4中的PDU会话资源更新指示消息是为双连接用户设备发送的,接入和移 动性管理功能收到该PDU会话资源更新指示消息后,可以从该PDU会话资源更新指示消息中获得接入节点的IP地址和TEID。如果,已经有被标记为第一基站的IP地址,而当前消息中携带的接入节点的IP地址不同于上述已经标记为第一基站的IP地址,则将该PDU会话资源更新指示消息中携带的IP地址对应的接入节点标记为第二基站。
进一步的,接入和移动性管理功能通过以上2个方法标记基站类型,该接入和移动性管理功能可用为此设置老化定时器,老化定时器超时后,将标记的基站类型清空,重新执行本实施例的学习过程。
基于上述的自学习过程,接入和移动性管理功能获知用户设备建立的业务流,哪些是建立在主接入节点上,哪些是建立在辅接入节点上。据此,接入和移动性管理功能可以参考前文移动管理设备识别用户设备的连接类型的方法,在此不再赘述。
进一步的,接入和移动性管理功能在通过自学习识别用户设备的接入点类型得到识别结果后,可以将该识别结果通知给会话管理设备、用户面功能以及策略控制功能。比如,将识别的接入点类型发送给会话管理设备、用户面功能以及策略控制功能;又比如,通过信令消息将用户为单连接用户设备或者双连接用户设备的信息通知给会话管理设备、用户面功能以及策略控制功能。
