Description

一种注册及会话建立的方法、终端和AMF实体 技术领域
本申请实施例涉及通信技术领域,尤其涉及一种终端的注册、会话建立的方法、终端和接入与移动管理功能(acess and mobility management function,AMF)实体。
背景技术
随着通信技术的发展和用户对通信网络的需求不断的提高,5G通信网络技术(也称第五代移动通信技术)的标准化正在快速的进行中。在5G通信网络技术中,引入了网络切片的逻辑概念。运营商会给终端预配置网络切片选择策略(network slice selection policy,NSSP),需要说明的是,终端也可以称为用户设备(user equipment,UE)。预配置的NSSP由一个或者多个规则(rule)组成,每个rule关联一个第三方应用程序(application,App)到一个单一网络切片选择信息(single network slice selection information,S-NSSAI)。UE需要使用某个App时,根据NSSP的rule映射出相应的S-NSSAI,并在S-NSSAI对应的网络切片建立协议数据单元((protocol data unit,PDU)会话(session)。
但是,可能存在UE没有被预配置某一访问公共陆地移动网(visited public land mobile network,VPLMN)的NSSP的情况,当UE漫游到该VPLMN下时,UE没有VPLMN的NSSP,无法确定在哪个切片上建立PDU会话。也可能存在,当UE漫游到某一VPLMN下时,UE获取到了该VPLMN的NSSP,但当UE需要使用归属地公共陆地移动网络(home public land mobile network,HPLMN)的App时,在VPLMN的NSSP中找不到对应的rule,这时UE也无法确定所使用的S-NSSAI来建立PDU会话。
发明内容
本申请实施例提供了一种终端的注册、会话建立的方法、终端和AMF实体,通过终端获取所在VPLMN或HPLMN的NSSP,以便于PDU会话建立过程中精确的确定VPLMN或HPLMN的S-NSSAI,完成PDU会话的建立。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例进行描述。
本申请实施例提供了一种注册、会话建立的方法、终端和AMF实体,应用于5G通信网络。在5G通信网络的核心网中引入了网络切片的逻辑概念,以及网络切片的结构。
网络切片是指支持特定通信业务需求的逻辑网络功能实体的集合,主要借助于软件定义网络(software defined netwoek,SND)技术与网络功能虚拟化(network function virtualization,NFV)技术,实现通信业务可定制化的服务。这里提到的逻辑网络功能实体可以包括下文提到的AMF实体、SMF实体和UPF实体,具体请参见图2中的描述。
NFV技术可实现底层物理资源到虚拟化资源的映射、构建虚拟机和加载网络功能(network function,NF);SDN技术可实现虚拟机之间的逻辑连接、构建承载信令和数据流的通路。网络切片最终实现无线接入网(radio acess network,RAN)与核心网(core network,CN)的网络功能实体之间的动态连接,配置端到端的业务链,实现灵活组网,从而实现网络可定制化的服务。运营商可以根据各个具体通信业务对容量、覆盖、速率、时延及可靠性等关键性能指标(key performance indicator,KPI)的需求确定网络切片,网络切片包括网络功能实体集合,从而为用户提供所需的电信服务业务和网络能力服务,满足特定的市场场景以及需求。
如图1所示为第三代合作伙伴计划(the third generation partnership project,3GPP)支持多个网络切片的网络框架示意图,3GPP将5G的网络切片的主要类型分为以下三大类:增强的移动宽带业务(enhanced mobile broadband,eMBB)类型的网络切片、海量物联网业务(massive internet o thing,mIoT)类型的网络切片和超可靠性时延业务(ultra-reliable and low latency communications,URLLC)类型的网络切片、多媒体设备等。mIoT类型的网络切片主要面向物联网的终端,该终端具有大规模、低移动性以及较低速率的需求。URLLC类型的网络切片主要面向车联网的终端,该终端对于时延和可靠性要求较高。例如,手机可接入eMBB类型的网络切片进行高速下载或者观看4K高清视频,传感器设备可以接入mMTC类型的网络切片进行小数据包的传输和系统配置的更新。
为了满足同一终端能够支持多种通信业务,提高用户体验,允许同一终端接入一个或多个网络切片,本申请实施例的技术方案可适用于一个终端接入一个或多个网络切片的场景。
也就是说,每个网络切片针对特定的终端,提供特定的服务。其中,在本申请实施例中,终端(terminal),也可以称为用户设备(user equipment,UE),可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经RAN与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(personal communication service,PCS)电话、 无绳电话、会话发起协议(session initiated protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备。无线终端也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device)、或用户装备(user equipment),本申请实施例中并不限定。按照业务类型划分,本发明实施例涉及的UE,可以是上文中对速率和移动性有较高需求的终端设备,例如手机、多媒体设备等,也可以是物联网的终端,还可以是车联网的终端。
一个网络切片实现到网络部署中为一个网络切片实例(network slice instance,NSI)。一个网络切片可以实现出多个网络切片实例。
一个UE可以同时使用多个NSI,NSI可以共用RAN设备和AMF实体,而会话管理功能(session management control function,SMF)实体和用户面功能(user plane function,UPF)实体为NSI特有的网元,如图2所示,图2为本申请实施例提供的一种5G通信网络的核心网结构示意图。
在本申请实施例中,AMF实体、SMF实体和UPF实体可以为核心网中的一个或多个服务器。
AMF实体具有UE的移动管理、注册管理、连接管理、合法监听、支持传输UE和SMF实体之间的会话管理(session management,SM)信息、接入认证和接入授权等功能。
SMF实体具有会话管理、漫游等功能。其中,会话管理功能,例如,会话建立、修改和释放,包括UPF和接入网(access network,AN)节点(node)的隧道维护。漫游功能可以包括计费数据收集、支持与外部(external)数据网络(data network,DN)进行认证/授权的信令传输。
UPF实体具有数据包路由和合法监听等功能。
在图2中,一个UE可以同时使用两个网络切片实例NSI1和NSI2,NSI1和NSI2共用RAN设备和AMF实体,SMF1实体和UPF1实体是NSI1特有的网元,SMF2实体和UPF2实体是NSI2特有的网元。UPF1实体、UPF2实体分别连接相对应的数据网络(data network)1和数据网络2。
其中,UE与RAN通过Uu接口连接;RAN与UPF1实体、UPF2实体之间的数据通过N3接口传输;RAN设备与AMF实体间的信令和数据通过N2接口;AMF实体与SMF1实体、SMF2实体间的信令和数据通过N11接口传输;SMF1实体与UPF1实体,以及SMF1实体与UPF1实体之间的信令与数据通过N4传输。需要说明的是,Uu接口、N2接口、N3接口、N11接口和N4接口已在标准中定义。
当UE漫游到访问公共陆地移动网VPLMN时,根据网络决策和UE签约,可以将漫游分为两种场景:归属地路由(home routed)和本地数据分流(local breakout)。其网络架构如图3和图4所示。
其中,图3为本申请实施例提供的一种local breakout场景的网络架构示意图。图4为本申请实施例提供的一种home routed场景的网络架构示意图。
当UE发起PDU会话建立请求时,AMF实体首先根据UE上报的S-NSSAI选择网络切片 NSI,再选择网络切片NSI对应的特有的网元,即SMF实体和UPF实体。
如图3所示,该网络架构为local breakout场景的网络架构。在local breakout场景下,UE漫游到VPLMN,发起PDU会话建立请求,VPLMN的AMF实体,简称V-AMF实体,首先根据UE上报的S-NSSAI选择VPLMN的网络切片V-NSI1,再选择V-NSI1对应的特有的网元,即V-SMF实体和V-UPF实体,该过程与非漫游情况类似。其中,V-SMF实体为UE所在VPLMN的SMF实体;V-UPF实体为UE所在VPLMN的UPF实体。
如图4所示,该网络架构为home routed场景的网络架构。在home routed场景下,UE漫游到VPLMN,该UE使用V-NSI1,该V-NSI1包括V-RAN设备和V-AMF实体,以及特有的网元V-SMF1实体和V-UPF1实体;该UE在归属地使用H-NSI2,该H-NSI2的特有网元为H-SMF2实体和H-UPF2实体。
当UE发起PDU会话建立请求时,V-AMF根据VPLMN的S-NSSAI选择V-SMF实体和根据HPLMN的S-NSSAI选择H-SMF实体,V-SMF实体和H-SMF实体分别选择V-UPF实体和H-UPF实体。上行数据传输是从UE到RAN设备到V-UPF实体再到H-UPF实体,下行反向即可。
下面结合附图对本申请实施例提供的会话建立方法进行说明。需要说明的是,下文中提到的AMF实体,若非特定注明,均是指VPLMN的V-AMF实体。
当UE从归属地漫游到VPLMN时,需要UE先进行网络注册,具体网络注册过程如图5所示,其过程可以包括以下步骤:
S110,UE向AMF实体发送注册请求(registration request)消息。
注册请求消息中包括第一参数,第一参数用于请求网络切片选择策略。在本申请实施例中,第一参数可以为需要NSSP指示(need NSSP indication)信息,用于向AMF实体请求NSSP。
注册请求消息中还可以包括UE的标识,该UE的标识可以为临时性标识,也就是为UE临时分配的标识,如全球唯一临时UE标识(globally unique temporary UE identity,GUTI),在本申请实施例中,该标识可以为UE上一次注册时,AMF实体分配给UE的标识。
S120,AMF实体根据注册请求消息从策略控制功能(policy control function,PCF)实体获取NSSP。
AMF实体根据注册请求消息中的UE的标识,如GUTI,以及第一参数从PCF实体获取网络切片的选择策略NSSP。
其中,PCF实体为一个逻辑的功能设备,可以为一个服务器,也可以为多个服务器,用于为控制面实体或UE提供策略,也就是说PCF实体用于策略的管理和控制。
AMF从PCF实体获取NSSP的过程可以具体为:如图5所示,S121和S122。
S121,AMF实体向策略控制功能(policy control function,PCF)实体发送用户设备上下文建立请求(UE context establishment request)消息。
用户设备上下文建立请求消息中第一参数和包括UE的标识。UE的标识可以为用户永久性标识(subscriber permanent identifier,SUPI),SUPI可以包括国际移动用户识别码(international mobile subscriber identification,IMSI)),网络接入标识(network access identifier,NAI)等。其中,UE的标识SUPI为所述AMF实体根据所述UE的标识GUTI确定的。例如,UE的SUPI为IMSI,AMF实体根据UE的标识GUTI,以及AMF实体中存储的UE的标识GUTI和标识IMSI的关系信息确定出UE的标识IMSI。换句 话讲,根据UE的临时性标识GUTI可以查找到UE的永久性标识IMSI。
S122,AMF实体接收PCF实体发送的用户上下文建立响应(UE context establishment response)消息。
PCF实体接收到AMF实体发送的用户上下文建立请求消息后,根据UE的IMSI,为UE建立在PCF实体内的上下文,并根据需要NSSP指示信息向AMF实体发送用户上下文建立响应消息,该用户上下文建立响应消息中包括UE的SUPI和该UE的NSSP。
AMF实体接收到用户上下文建立响应消息后执行步骤S130。
S130,AMF实体向UE发送注册接受(registration accept)消息。
注册接受消息中包括NSSP,即UE获得当前注册的VPLMN下的NSSP。相比现有技术,UE可以从AMF实体获取当前注册VPLMN的NSSP,而不是从AMF实体获取HPLMN的NSSAI和VPLMN的NSSAI的映射关系。当UE根据获取到VLPMN的NSSP时,可以根据NSSP准确的确定出当前VPLMN下App该使用的S-NSSAI。
可选地,如图5所示,在本申请实施例中,在AMF实体接收到UE发送的注册请求消息后,该方法还可以包括:
S140,AMF实体向用户数据管理(user data management,UDM)实体发送更新位置(update location)信息。
UDM实体可以为一个服务器,用于用户数据的管理,比如位置管理,签约管理等等。
AMF实体根据接收到的注册请求消息中的UE的GUTI确定UE的IMSI,并向UDM发送更新位置信息。UDM接收AMF发送的更新位置信息,并根据UE的SUPI更新UE当前的AMF实体,并向AMF实体发送更新位置回应(update location ack)消息。
S150,AMF实体接收UDM实体发送的更新位置回应消息。
该更新位置回应消息中包括UE的签约信息,以用于后续AMF提供签约信息包括的相应服务。
当UE在VPLMN完成注册之后,需要进行会话建立的时候,执行图6、图7和图8中的步骤:
图6为本发明实施例提供的一种会话建立的方法流程图。如图6所示,该方法可以包括以下步骤:
S201,UE向AMF实体发送第一消息。
建立会话时,需要UE向AMF实体发起第一消息。第一消息包含第一信息(information),第一网络切片选择信息,以及第二网络切片选择信息。
其中,第一信息包含请求建立PDU会话的信息。在本申请实施例中,第一信息可以为一个消息,例如PDU会话建立请求消息(PDU session establishment request)。
第一网络切片选择信息用于AMF实体选择第一SMF实体,例如,第一网络切片选择信息可以为VPLMN的S-NSSAI;第二网络切片选择信息用于AMF选择第二SMF实体,例如,第二网络切片选择信息可以为HPLMN的S-NSSAI。
其中,第一网络切片选择信息和第二网络切片选择信息均是用于标识和确定网络切片的。第一网络切片选择信息和第二网络切片选择信息中均可以包括网络切片的类型,租用该网络切片的厂商名称等信息。
S202,AMF实体根据第一网络切片选择信息确定第一SMF实体,根据第二网络切片选择信息确定第二SMF实体。
