技术领域
本申请涉及通信技术领域,并且更具体地,涉及执行在线签约的方法和装置。
背景技术
当终端设备接入在线签约网络后,在线签约网络中的设备可以按照在线签约策略对终端设备执行在线签约。当在线签约网络中的设备无法对终端设备进行服务或者当在线签约网络因为负载均衡、无线资源状况等因素需要更换服务终端设备的设备时,终端设备需要执行切换,并由在线签约网络中的其他设备服务该终端设备。然而,在线签约网络中的其他设备可能无法对终端设备执行在线签约。因此,终端设备执行切换后,如何使在线签约网络仍然可以对终端设备执行在线签约是一个亟待解决的问题。
发明内容

下面对本申请中的一些术语进行说明。
1、非公共网络(non-public network,NPN)
NPN是一种区别于公共网络的为特定用户提供服务的网络,NPN可以分为两种类型,分别为独立组网的NPN(standalone NPN,SNPN)和非独立组网的NPN(public network integrated NPN,PNI-NPN)。
其中,SNPN的核心网独立于公共陆地移动网(public land mobile network,PLMN)。PNI-NPN可以理解为是PLMN,只是该PLMN会提供特殊的切片和/或网络数据来提供NPN业务。
2、在线签约
如图2所示,UE在没有获取接入非公共网络的签约数据(例如,用于鉴权的凭证“credential”)时,需要采用默认凭证(default credential)或者PLMN凭证来接入在线签约网络。当UE成功接入(或者注册于)在线签约网络后,服务开通服务器(provisioning server,PVS)通过在线签约网络向UE提供用于接入NPN的签约数据(例如,凭证)。
下面介绍本申请提出的方案适用的场景:
为了接入NPN,UE可以先接入到在线签约网络中,获取接入NPN的签约数据。UE在接入到在线签约网络后,由AMF对UE执行在线签约,该AMF支持在线签约功能,下文将该AMF称为S-AMF。当S-AMF无法继续对UE执行在线签约时或者由于在线签约网络因为考虑负载均衡或者无线资源状况等因素,需要更换服务UE的AMF时,需要执行切换。本申请所提出的方案用于实现在执行切换时,选择一个新的AMF(下文将该新的AMF称为T-AMF),对UE继续执行在线签约。
其中,S-AMF无法继续对UE执行在线签约的原因可以为以下中的任意一项:
1、UE移出了S-AMF的服务范围。
2、S-AMF损坏或出现故障而无法正常运行。
3、S-AMF的负载过大,出于负载均衡的考虑S-AMF不再适合对UE执行在线签约。
4、S-AMF服务的接入网设备(下文将该接入网设备称为S-RAN)的无线资源紧缺,出于无线资源状况的考虑,接入网设备不再适合服务UE,因此需要更换接入网设备。下文将更换的接入网设备称为T-RAN。由于服务T-RAN的AMF(下文将称为T-AMF)不同于S-AMF,因此需要更换AMF。
下面以UE移出了S-AMF的服务范围为例,对本申请的方案进行详细描述。应理解,在一种可能的实现方式中,对UE进行服务的接入网设备也发生了改变,由第二接入网设备变为了第一接入网设备。
图3示出了本申请提供的一种方案,此时,UE处于无线资源控制(radio resource control,RRC)连接态。
S301,当S-RAN(第二接入网设备的一例)确定T-RAN(第一接入网设备的一例)更适合服务UE时,S-RAN向S-AMF(第二核心网设备的一例)发送第二请求消息,该第二请求消息请求将服务UE的RAN由S-RAN切换至T-RAN。相应地,S-AMF接收该第二请求消息。
一种可能的实现方式中,该第二请求消息中包括T-RAN的标识、源至目标透传容器(source to target transparent container)。
其中,T-RAN的标识用于识别T-RAN;源至目标透传容器为S-RAN创建的,该容器包括需要由T-RAN使用的信息。
S302,当S-AMF无法对UE进行服务时,S-AMF获取第三信息,根据第三信息选择T-AMF(第一核心网设备的一例),该T-AMF支持在线签约功能。
其中,该第三信息指示UE执行在线签约。应理解,第三信息指示UE执行在线签约是指,第三信息指示UE接入网络的目的为在线签约。
即,S-AMF根据第三信息确定需要为UE选择支持在线签约功能的AMF,进而选择该T-AMF。
下面介绍S-AMF获取第三信息的几种方式:
方式1:
S-AMF从UE获取该第三信息。
一种可能的实现方式中,UE可以向S-RAN发送AN消息,该AN消息中包括NAS注册请求消息。该第三信息可以承载于NAS注册请求消息中。例如,该第三信息可以为注册类型信息,该注册类型信息指示UE执行在线签约。一种可能的实现方式中,注册类型可以为以下注册类型中的一种或多种:在线签约注册类型(Onboarding)、独立私网在线签约注册类型(SNPN Onboarding)、移动性注册更新与在线签约(Mobility Registration Update with Onboarding)注册类型、移动性注册更新与独立私网在线签约(Mobility Registration Update with SNPN Onboarding)注册类型、移动性注册更新(Mobility Registration Update)注册类型。
S-RAN可以向S-AMF发送该NAS注册请求消息。
S-AMF从NAS注册请求消息中获取第三信息。
方式2:
一种可能的实现方式中,S-AMF从本地获取该第三信息。该第三信息包括以下中的一项或多项:
UE的注册类型信息、数据网络名称(data network name,DNN)信息、网络切片信息(network slice selection assistance information,NSSAI)、第一数值的信息。
其中,UE的注册类型信息指示UE执行在线签约,一种可能的实现方式中,UE的注册类型可以为以下注册类型中的一种或多种:在线签约注册类型(Onboarding)、独立私网在线签约注册类型(SNPN Onboarding)、移动性注册更新与在线签约(Mobility Registration Update with Onboarding)注册类型、移动性注册更新与独立私网在线签约(Mobility Registration Update with SNPN Onboarding)注册类型、移动性注册更新(Mobility Registration Update)注册类型。
一种可能的实现方式中,该第一数值指示UE已注册到在线签约网络中的时长,或者指示UE允许注册到在线签约网络中的剩余时长。例如,该第一数值可以为计时器的当前值。该计时器的类型可以为正计时器或倒计时器,本申请对此不作限定。
即,UE的注册类型信息也可以显式或者隐式指示该UE执行在线签约,数据网络名称、切片信息、第一数值均可以隐式指示该UE执行在线签约。
应理解,在一种可能的实现方式中,UE注册到在线签约网络中后,可以采用特定的DNN和/或特定的NSSAI来建立特定的会话,该会话仅限于执行在线签约。一种可能的实 现方式中,该会话可以是分组数据单元(packet data unit,PDU)会话。
应理解,在一种可能的实现方式中,数据网络名称、网络切片信息、第一数值可以是UE的上下文信息。
S303,S-AMF向T-AMF发送第一信息。相应地,T-AMF接收该第一信息。该第一信息指示UE执行在线签约。
在一种可能的实现方式中,该第一信息可以承载于第三请求消息中,该第三请求消息请求建立UE的上下文。
在一种可能的实现方式中,该第三请求消息中可以包括T-RAN的标识信息、源至目标透传容器信息(source to target transparent container)、UE的上下文信息,其中UE的上下文信息包括UE的标识,例如UE的永久标识符(subscription permanent identifier,SUPI)。
在一种可能的实现方式中,该第一信息可以为显式的指示信息,即S-AMF直接指示该UE执行在线签约。
在另一种可能的实现方式中,该第一信息可以为隐式的指示信息,此时该第一信息包括以下中的一项或多项:
数据网络名称信息、网络切片信息、第一数值的信息。
在另一种可能的实现方式中,该第一信息可以既包括显式的指示信息,又包括隐式的指示信息。
S304,T-AMF根据第一信息对UE执行在线签约。
应理解,T-AMF根据第一信息,确定UE为执行在线签约的UE,并对UE执行在线签约。
即,T-AMF可以代替S-AMF继续对UE执行在线签约。
此外,T-AMF在对UE执行在线签约的过程中,为了防止UE一直驻留到或者注册于在线签约网络中占用网络资源,T-AMF还可以按照下述方式进行操作。
方式1:
当第一信息中包括第一数值的信息时,T-AMF可以开启第一计时器,并且将第一计时器的起始值设置为该第一数值。
在第一数值指示UE已注册到网络中的时长的情况下,该第一计时器可以为正计时器。当第一计时器的值增大到第一阈值时,T-AMF执行UE的去注册流程。在一种可能的实现方式中,第一阈值指示UE能注册于(或者驻留到)在线签约网络中的最长时间。在另一种可能的实现方式中,第一阈值可以大于、等于或者小于UE从RRC连接态变为RRC空闲态或者变为RRC inactive态的时长。
在第一数值指示UE允许注册到网络中的剩余时长的情况下,该第一计时器可以为倒计时器。当第一计时器的值减小到第二阈值时,T-AMF执行UE的去注册流程。
在一种可能的实现方式中,第二阈值可以为零。
方式2:
T-AMF可以开启第二计时器。
在第二计时器为正计时器的情况下,T-AMF可以将第二计时器的起始值设置为零或者第二阈值,当第二计时器的值增大到第一阈值时,T-AMF执行UE的去注册流程。
在第二计时器为倒计时器的情况下,T-AMF可以将第二计时器的起始值设置为第一 阈值,当第二计时器的值减小到第二阈值或者零时,T-AMF执行UE的去注册流程。
应理解,上述第一阈值的信息和第二阈值的信息可以是预先配置到T-AMF中的。或者,T-AMF可以从S-AMF获取第二信息,该第二信息指示上述第一阈值和/或第二阈值。
应理解,上述T-AMF执行UE的去注册流程的目的是将UE从在线签约网络中去注册,使UE不再驻留到或者注册于在线签约网络中而一直占用网络资源。
S305,T-AMF根据T-RAN的标识信息确定T-RAN,并向T-RAN发送切换请求消息。相应地,T-RAN接收该切换请求消息。
在一种可能的实现方式中,该切换请求消息中包括源至目标透传容器信息。
S306,T-RAN向T-AMF发送第二响应消息,该第二响应消息用于响应切换请求消息。相应地,T-AMF接收该第二响应消息。
在一种可能的实现方式中,该第二响应消息中包括目标至源透传容器信息,该目标至源透传容器信息中包括UE容器信息。该UE容器信息中包括接入层信息和非接入层信息。
S307,T-AMF向S-AMF发送第三响应消息,该第三响应消息用于响应第三请求消息。相应地,S-AMF接收该第三响应消息。
在一种可能的实现方式中,该第三响应消息中包括目标至源透传容器信息。

S310,UE根据该第二切换指令,执行切换。当UE成功切换至T-RAN时,UE向T-RAN发送第一指示信息。相应地,T-RAN接收该第一指示信息。
在一种可能的实现方式中,该第一指示信息指示UE成功执行切换。
S311,T-RAN向T-AMF发送第二指示信息。相应地,T-AMF接收该第二指示信息。
在一种可能的实现方式中,该第二指示信息指示T-RAN成功执行切换。
S312,T-AMF向S-AMF发送N2信息通知消息。相应地,S-AMF接收该N2信息通知消息。
可选地,该方法还包括:S313,S-AMF向T-AMF发送N2信息通知响应消息。相应地,T-AMF接收该N2信息通知响应消息。
S314,S-AMF根据该N2信息通知消息开启第三定时器,当第三定时器到时后,S-AMF向S-RAN发送UE上下文释放指令。相应地,S-RAN接收该UE上下文释放指令。
例如,当第三定时器的值增大到第三阈值,或者减小到第四阈值时,S-AMF向S-RAN发送UE上下文释放指令。
S315,当S-RAN根据UE上下文释放指令释放了UE的上下文时,S-RAN向S-AMF发送UE上下文释放完成消息。
S316,UE发起移动性注册流程。
该流程包括:
UE向T-RAN发送AN消息,该AN消息中包括AN参数和NAS注册请求消息。相应地,T-RAN接收该AN消息。其中,该NAS注册请求消息中包括注册类型信息,该注 册类型信息指示UE的注册类型为移动性注册更新。

根据本申请的方案,在终端设备处于RRC连接态的情况下,当S-AMF无法为终端设备执行在线签约时,S-AMF可以选择支持在线签约功能的T-AMF。由于当S-AMF无法为终端设备执行在线签约时,S-AMF选择的AMF可能不支持在线签约功能。因此,采用本申请的方案可以使得T-AMF继续为终端设备执行在线签约。此外,T-AMF在对终端设备执行在线签约时,可以开启特定的计时器,从而防止终端设备一直驻留到在线签约网络中,提高网络资源的利用率。
图4示出了本申请提供的另一种方案,此时,UE处于RRC空闲态。
S401,UE向T-RAN发送第四信息,该第四信息指示UE执行在线签约。相应地,T-RAN接收该第四信息。

可选地,S-AMF向T-AMF发送第一信息,第一信息指示UE执行在线签约。例如, 将该第一信息承载于该第四响应消息中进行发送。
在一种可能的实现方式中,该第一信息可以为显式的指示信息,即S-AMF直接指示该UE执行在线签约。
在另一种可能的实现方式中,该第一信息可以为隐式的指示信息,此时该第一信息包括以下中的一项或多项:

S408,UE向T-AMF发送注册完成消息。
根据本申请的方案,在终端设备处于RRC空闲态的情况下,当S-AMF无法为终端设备执行在线签约时,T-RAN可以选择支持在线签约功能的T-AMF。由于当S-AMF无法为终端设备执行在线签约时,T-RAN选择的AMF可能不支持在线签约功能。因此,采用本申请的方案可以使得T-AMF继续为终端设备执行在线签约。此外,T-AMF在对终端设备执行在线签约时,可以开启特定的计时器,从而防止终端设备一直驻留到在线签约网络中,提高网络资源的利用率。
图5示出了本申请提供的另一种方案,此时,UE处于RRC空闲态。
S501,UE向T-RAN发送AN消息。该AN消息中包括AN参数和NAS注册请求消息。

应理解,本申请对第一信息承载于NAS注册请求消息中的方式不作限定。
S503,T-RAN选择初始AMF(第三核心网设备的一例),并向初始AMF发送NAS注册请求消息。
应理解,当该方法包括S502时,由于T-RAN并不对NAS注册请求消息进行解析,所以T-RAN并没有获知终端设备执行在线签约。因此,T-RAN在选择初始AMF时,可能选择不支持在线签约功能的AMF。
S504,初始AMF获取第五信息,第五信息指示UE执行在线签约。
下面介绍初始AMF获取第五信息的方式:
方式1:
当该方法包括S502时,初始AMF从NAS注册请求消息中获取第五信息。

此外,初始AMF还可以向S-AMF发送拒绝指示信息,指示S-AMF注册流程并没有在初始AMF处完成。
应理解,初始AMF在获取第五信息之后,可以进行判断,如果初始AMF支持在线签约功能,可以由初始AMF对UE执行在线签约;如果初始AMF不支持在线签约功能,初始AMF可以继续确定T-AMF。
下面介绍初始AMF确定T-AMF的方式:
方式1:
初始AMF根据预配置的至少一个AMF网元的能力信息,确定T-AMF。
方式2:

初始AMF根据第一响应消息,确定T-AMF。
S506,T-AMF获取第一信息,该第一信息指示UE执行在线签约。
下面介绍T-AMF获取第一信息的方式:
方式1:
初始AMF向T-AMF发送第一信息。相应地,T-AMF接收该第一信息。
例如,初始AMF可以向T-AMF发送N1消息通知消息,该N1消息通知消息中包括NAS消息、UE的标识信息、UE的上下文信息中的一项或多项。当该方法包括S502时,该第一信息为NAS消息中携带的第五信息。或者,UE的上下文信息中可以包括数据网络名称信息、网络切片信息、第一数值的信息中的一项或多项,数据网络名称信息、网络切片信息、第一数值均可以隐式指示UE执行在线签约。
应理解,在一种可能的实现方式中,UE注册到在线签约网络中后,可以采用特定的DNN和/或特定的NSSAI来建立特定的会话,该会话仅限于执行在线签约。一种可能的实现方式中,该会话可以是分组数据单元(packet data unit,PDU)会话。
方式2:
S-AMF向T-AMF发送第一信息。相应地,T-AMF接收该第一信息。
例如,T-AMF向S-AMF发送第四请求消息,该第四请求消息用于请求UE的上下文信息。S-AMF可以将第一信息承载于第四响应消息中,向T-AMF发送第四响应消息。该第四响应消息中包括UE的上下文的信息。
在一种可能的实现方式中,该第一信息可以为显式的指示信息,即S-AMF直接指示该UE执行在线签约。
在另一种可能的实现方式中,该第一信息可以为隐式的指示信息,此时该第一信息包 括以下中的一项或多项:
数据网络名称信息、网络切片信息、第一数值的信息。
应理解,在一种可能的实现方式中,UE注册到在线签约网络中后,可以采用特定的DNN和/或特定的NSSAI来建立特定的会话,该会话仅限于执行在线签约。一种可能的实现方式中,该会话可以是分组数据单元(packet data unit,PDU)会话。
在另一种可能的实现方式中,该第一信息可以既包括显式的指示信息,又包括隐式的指示信息。
S507,T-AMF根据第一信息对UE执行在线签约。
该过程与S304相同,具体可以参考S304的描述。
S508,而后执行对该UE的鉴权流程,当鉴权成功后,T-AMF向UE发送注册成功消息。
在一种可能的实现方式中,该注册成功消息中还包括T-AMF为该UE分配的临时标识。例如,该临时标识可以为5G-GUTI。该临时标识指示UE为执行在线签约的UE。
此外,T-AMF向S-AMF发送注册状态更新消息,该注册状态更新消息指示UE在T-AMF成功注册。
S509,UE向T-AMF发送注册完成消息。
根据本申请的方案,在终端设备处于RRC空闲态的情况下,当S-AMF无法为终端设备执行在线签约时,T-RAN可以按照现有机制选择初始AMF。当初始AMF不支持在线签约功能时,初始AMF进一步确定T-AMF。由于当S-AMF无法为终端设备执行在线签约时,T-RAN选择的AMF可能不支持在线签约功能。因此,采用本申请的方案可以使得T-AMF继续为终端设备执行在线签约。此外,T-AMF在对终端设备执行在线签约时,可以开启特定的计时器,从而防止终端设备一直驻留到在线签约网络中,提高网络资源的利用率。
