Description

一种配置网络切片标识的方法、设备及计算机存储介质 技术领域
本发明实施例涉及无线通信技术领域,尤其涉及一种配置网络切片标识的方法、设备及计算机存储介质。
背景技术
在长期演进(LTE,Long Term Evolution)系统中,为了避免网络过载现象的发生,引入了接入控制准入(ACB,Access Control Barring)机制。而随着通信技术的发展,第五代移动通信技术(5G,5th Generation)的研究也已经展开。5G的无线接入叫New Radio,简称NR。在5G NR中,引入了网络切片(network slice)的概念,不同的网络切片在无线接入网络(RAN,Radio)Access Network)侧和核心网(CN,Core Network)侧具有相应的网络切片实例(instance),由于不同的网络切片实例instance之间具有一定的隔离特性。
目前,终端需要进入连接态并且进行附着attach后,才能够获取网络切片信息,网络侧只能基于终端获取网络切片信息的行为来针对网络切片进行接入控制。因此,当终端处于由空闲态转为连接态的过程中,如果目标网络切片已经过载,网络侧也只能在终端进入连接态之后,再根据连接态终端发送的消息中所携带的目标网络切片标识针对该目标网络切片进行接入控制,释放release终端。从而增加了终端与网络侧之间的信令资源消耗,在终端与网络侧之间产生了信令资源的浪费,也增加了接入控制的时延。
发明内容
本发明实施例期望提供一种配置网络切片标识的方法、设备及计算机存储介质;利用本发明实施例所提供的技术方案所配置的网络切片标识进行接入控制,能够降低信令资源消耗,避免了终端与网络侧之间信令资源的浪费,减少了接入控制的时延。

向用户设备UE发送承载有所述第一类网络切片的NSSAI以及对应的SSI的下行消息。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
目前在5G系统的相关技术中提出了网络切片slice的概念;其本质上就是将运营商的物理网络在逻辑上划分为多个虚拟网络,每一个虚拟网络根据不同的服务需求进行划分,比如可以根据时延、带宽、优先级、安全性和可靠性等服务需求信息进行划分,从而能够灵活的应对不同的网络应 用场景。因此,不同网络切片(也就是虚拟网络)之间相互隔离,以使得一个网络切片的错误或故障不会影响到其它网络切片的正常通信。
基于上述针对网络切片的说明,可以得知,网络切片类型可以包括接入网络切片Access Network slice、核心网络切片Core Network slice以及数据网络及服务网络切片Data Network and Service slice。所以,针对网络切片进行接入控制AC,所涉及到的网络侧设备包括5G系统的无线接入网设备,比如gNB;还可以包括5G系统的核心网设备,比如核心访问与移动性管理(AMF,Core Access and Mobility Management Function)。因此,本发明实施例的技术方案可以非典型性地应用于图1所示的网络架构场景,在该场景中,终端可以接入到无线接入网RAN后,通过N2接口接入到5G核心网;也可以直接通过N1接口与5G核心网进行连接。需要说明的是,N1是UE和AMF的NAS信令接口,N2是gNB和AMF之间的接口。另外,在图1所示的场景中,无线接入网RAN设备可以包括gNB;5G核心网设备可以包括AMF;需要说明的是,在图1所示架构中,对于单一的AMF而言,RAN设备的数量可以是一个或者多个,以gNB为例,可以为多个小区提供通信覆盖,通常可以将这些小区配置为相同的跟踪区(TA,Tracking Area),也就是说,多个小区可以配置相同的TA,但对于单个小区而言,仅能属于一个TA。
用户设备(UE,User Equipment)可以包括蜂窝电话、智能电话、会话发起协议(SIP)电话、膝上型计算机、个人数字助理(PDA)、卫星无线电、全球定位系统、多媒体设备、视频设备、数字音频播放器(例如,MP3播放器)、照相机、游戏控制台、平板计算机、或任何其它具有类似功能的设备。与此同时,用户设备还可以被本领域技术人员称为终端、移动站、订户站、移动单元、订户单元、无线单元、远程单元、移动设备、无线设备、无线通信设备、远程设备、移动订户站、接入终端、移动终端、无线终端、远程终端、手持机、用户代理、移动客户端、客户端、或某种其它适当的术语。
基于图1所示的网络架构,在目前相关的网络切片机制中,通常采用网络切片选择辅助信息(NSSAI,Network Slice Selection Assistance Information)来对网络切片进行标识,而NSSAI包括服务及网络切片类型(SST,Service and Slice Type)信息和服务及网络切片区分(SSD,Service and Slice Differentiator),SST与SSD两者的总长度达到了32比特。因此,用来标识单个网络切片的NSSAI的长度至少为32比特;而每个UE目前能够并行支持8个网络切片,因此,对于每个UE而言,其支持的网络切片的标识信息,也就是NSSAI的总长度最长可以达到32×8=256比特。这个长度 远远超过了一些传输信道中针对传输消息所设定的长度,比如公共控制信道(CCCH,Common Control Channel)信道上针对第三类消息MSG3所设定长度限制为48比特。因此,当UE与网络侧设备之间需要针对网络切片进行相关的控制及处理,那就只能够在某些为传输消息设定较大的传输信道上传输NSSAI。不仅增加了信令资源消耗,避免了UE与网络侧之间信令资源的浪费,而且限制了适用于针对网络切片进行相关控制和处理的适用场景。
结合上述阐述,本发明实施例期望通过提出一种配置网络切片标识的方法、设备及计算机存储介质,以实现网络切片短标识(SSI,Shortened Slice Index)的配置。从而节省信令资源的消耗,还扩大了针对网络切片进行控制和处理的适用场景。基于此,提出以下实施例。
实施例一
参见图2,其示出了本发明实施例提供的一种配置网络切片标识的方法,所述方法应用于网络侧设备,可以理解地,该网络侧设备既可以包括无线接入网设备,如gNB;也可以包括核心网设备,如AMF;该方法可以包括:
S201:基于设定的划分粒度为第一类网络切片的NSSAI配置对应的SSI;其中,所述NSSAI与对应的SSI均指示相同的网络切片,且所述SSI的长度短于所述NSSAI;
S202:向用户设备UE发送承载有所述第一类网络切片的NSSAI以及对应的SSI的下行消息。
在本实施例中,优选地,所述第一类网络切片包括已注册的网络切片或为所述UE配置的网络切片;相应来说,已注册的网络切片的NSSAI具体可以为Allowed NSSAI;为所述UE配置的网络切片的NSSAI具体可以为Configured NSSAI。
基于图2所示的技术方案,对于连接态UE来说,实现了网络侧设备和UE对所支持的网络切片的NSSAI及对应的SSI达成了一致,从而能够使得后续UE在需要和网络侧针对网络切片的接入控制等相关情况进行处理时,能够利用SSI来指示网络切片,从而降低了信令的资源消耗,避免了UE与网络侧之间信令资源的浪费,扩大了针对网络切片进行控制和处理的适用场景。
在上述优选实例中,对于已注册的网络切片,所述向用户设备UE发送承载有所述第一类网络切片的NSSAI以及对应的SSI的下行消息,包括:将所述已注册的网络切片的NSSAI以及对应的SSI承载于注册回应消息中发送至所述UE。具体来说,当UE处于非激活态inactive和空闲态idle时, 网络侧设备维护了终端已经注册过的网络切片的NSSAI,因此,当UE已经执行完注册过程后,网络侧设备可以将已注册的网络切片的NSSAI以及对应的SSI承载于注册回应消息中发送至所述UE。
在上述优选实例中,网络侧设备还可以在UE开机后的注册过程中为所述UE配置网络切片,因此,在所述基于设定的划分粒度为第一类网络切片的NSSAI配置对应的SSI之前,所述方法还包括:
在所述UE的注册过程中为所述UE配置网络切片;
相应地,所述向用户设备UE发送承载有所述第一类网络切片的NSSAI以及对应的SSI的下行消息,包括:
将所述为所述UE配置的网络切片的NSSAI以及对应的SSI承载于注册回应消息中发送至所述UE。可以理解地,由于网络侧在UE注册时为UE配置了网络切片,因此,仍然可以将所述为所述UE配置的网络切片的NSSAI以及对应的SSI承载于注册回应消息中发送至所述UE。
对于图2所示的技术方案,在一种可能的实现方式中,所述设定的划分粒度至少包括:以跟踪区TA为粒度、以路由区(RA,Routing Area)为粒度和以UE为粒度。基于此,所述下行消息中还可以包括用于指示所述划分粒度的指示信息;以便UE能够根据指示的划分粒度来获得网络切片的NSSAI及对应的SSI。
针对上述实现方式,当所述UE注册到多个TA,且所述设定的划分粒度以TA为粒度时,基于设定的划分粒度为第一类网络切片的NSSAI配置对应的SSI,包括:
根据每个TA的第一类网络切片数量确定每个TA中SSI长度;
基于每个TA中SSI长度,分别在各TA中统一为第一类网络切片的NSSAI设置对应的SSI编号。
针对上述实现方式,当所述设定的划分粒度以RA为粒度,且所述设定的划分粒度以RA为粒度时,基于设定的划分粒度为第一类网络切片的NSSAI配置对应的SSI,包括:
根据每个RA的第一类网络切片数量确定每个RA中SSI长度;
基于每个RA中SSI长度,分别在各RA中统一为第一类网络切片的NSSAI设置对应的SSI编号。
针对上述实现方式,当所述设定的划分粒度以UE为粒度时,基于设定的划分粒度为第一类网络切片的NSSAI配置对应的SSI,包括:针对所述UE对应的第一类网络切片的NSSAI统一设置SSI编号。
具体来说,由于UE能够注册到多个TA或RA,那么就需要在不同的TA或RA针对网络切片配置SSI。举例来说,设定UE注册了6个网络切 片slice分别为S1至S6,对应的切片标识分别是NSSAI a,NSSAI b,NSSAI c,NSSAI d,NSSAI e,NSSAI f;6个网络切片分别位于TA1,TA2,TA3,具体如图3所示,S1和S2位于TA1,S3、S4、S5位于TA2;S6位于TA3。
针对上述举例,以TA为粒度,那就首先根据每个TA的的切片数,确定该TA里的SSI长度,比如,假设一个TA的切片数为n,则n为1或2时;SSI长度为1个比特;n为3或4时,SSI长度为2个比特;n为5或6或7或8时,SSI长度为3个比特。以此,基于每个TA中SSI长度,分别在各TA中统一为第一类网络切片的NSSAI设置对应的SSI编号。由此可知,由于S1和S2位于TA1,因此,SSI的长度为1个比特,所以S1和S2在TA1中的统一编号分别是0,1;由于S3、S4、S5位于TA2,因此,SSI长度为2个比特,所述S3、S4、S5在TA2中的统一编号分别是0,1,2;由于S6位于TA3,因此,SSI长度为1个比特,所述S6在TA3中的统一编号为1;将上述编号再结合TA标识,则完成了以TA为粒度对网络切片S1-S6的NSSAI对应的SSI的配置。
针对上述举例,以RA为粒度,设定S1至S6位于同一RA,如图3所示,于是针对S1至S6在该RA内统一编号,S1至S6在该RA内的编号分别是1,2,3,4,5,6;假设UE还注册了N个切片位于另一RA,则N个切片在另一个RA内同一编号,分别是1,2,3,……N;最后将各网络切片在RA中的编号再结合各网络切片所在RA的标识,则完成了以RA为粒度对网络切片的NSSAI对应的SSI的配置。
由于UE注册的网络切片S1至S6位于同一RA,因此,以UE为粒度时,也是针对S1至S6统一编号,分别是1,2,3,4,5,6;所以以UE为粒度的编号结果与UE注册的网络切片S1至S6位于同一RA时以RA为粒度的编号结果一致。具体编号示例如表1所示:
切片标识 以RA为粒度 以TA为粒度
NSSAI a SSI=0 TA=1,SSI=0
NSSAI b SSI=1 TA=1,SSI=1
NSSAI c SSI=2 TA=2,SSI=0
NSSAI d SSI=3 TA=2,SSI=1
NSSAI e SSI=4 TA=2,SSI=2
NSSAI f SSI=5 TA=3,SSI=1
表1
可以理解地,上述不仅能够应用于为第一类网络切片的NSSAI配置SSI;还能够应用于为其他网络发送给终端的网络切片的NSSAI配置SSI,本实施例在此不再赘述。
需要说明的是,当网络侧设备与UE已经对所支持的网络切片的NSSAI及对应的SSI达成了一致后,当涉及到针对NSSAI的增加,删除或者修改情况下,还可以进行冲刷flush操作,也就是,重新为NSSAI配置对应的SSI。
对于图2所示的技术方案,除了网络侧向终端发送NSSAI及对应的SSI;终端也能够向网络侧发送NSSAI及对应的SSI;在一种可能的实现方式中,所述方法还包括:
接收所述UE发送的第二类网络切片的NSSAI以及所述UE为所述第二类网络切片的NSSAI所对应设置的SSI;其中,所述第二类网路切片包括在已注册的网络切片或为所述UE配置的网络切片中,UE请求为NSSAI设置对应的SSI的网络切片Requested NSSAI。
具体来说,如果Requested NSSAI是基于Configured NSSAI的,而configured NSSAI中没有为该NSSAI配置SSI,则,终端可以为基于Configured NSSAI的Requested NSSAI的进行编号,并汇报给网络侧。
同样的,如果Requested NSSAI是基于Allowed NSSAI的,而Allowed NSSAI中没有为该NSSAI配置SSI,则,终端可以为基于Allowed NSSAI的Requested NSSAI的进行编号,并汇报给网络侧。
需要说明的是,针对具体的网络侧设备,终端发送的具体对象可以是接入设备(如gNB),也可能是核心网设备(如AMF),也可能是接入设备和核心网设备(gNB和AMF)。因此,针对具体对象的情况不同,终端所发送的第二类网络切片的NSSAI及对应的SSI的适用环境也相应有以下区别:
情况一:相应于仅由网络侧设备的接入设备接收到第二类网络切片的NSSAI以及所述UE为所述第二类网络切片的NSSAI所对应设置的SSI,则所述UE为第二类网络切片的NSSAI所对应设置的SSI仅适用于接入层AS。
需要说明的是,这种情况仅适合于连接态UE,UE也只把SSI和NSSAI的对应关系提供给gNB,而对于AMF透明。连接态UE如果仅在空口使用SSI,在建立了SSI和NSSAI的对应关系后,可以使用SSI替代NSSAI。
情况二:相应于仅由网络侧设备的核心网设备接收到所述第二类网络切片的NSSAI以及所述UE为所述第二类网络切片的NSSAI所对应设置的SSI,则所述UE为第二类网络切片的NSSAI所对应设置的SSI仅适用于非 接入层NAS。
需要说明的是,这种情况主要是针对于UE处于idle态时,gNB不保存UE的上下文context,因此,基站无法感知SSI与NSSAI的对应关系。
情况三:相应于由网络侧设备的接入设备和核心网设备接收到所述第二类网络切片的NSSAI以及所述UE为所述第二类网络切片的NSSAI所对应设置的SSI,则所述UE为第二类网络切片的NSSAI所对应设置的SSI能够适用于AS和NAS。
需要说明的是,这种情况适合于UE处于非激活态inactive和连接态connected时。在inactive状态,SSI与NSSAI的对应关系至少保存于锚基站anchor gNB。对于连接态,SSI与NSSAI的对应关系可以保存在服务基站serving gNB和AMF。
此外,所述方法还包括:接收UE在注册成功后发送的未注册的网络切片的NSSAI以及由UE为未注册的网络切片的NSSAI所对应设置的SSI。
需要说明的是,对于尚未在网络侧设备进行注册的网络切片,UE并不强制采用SSI,因为网络侧设备中没有这些网络切片信息,所以即使注册了网络也未必能够接纳并配置为Allowed NSSAI,因此,对这些网络切片,可选的,可以在UE注册成功后再进行SSI编号。
本实施例提供的一种配置网络切片标识的方法,网络侧设备为NSSAI配置对应的SSI后发送给UE,从而实现了网络设备和UE对所支持的网络切片的NSSAI及对应的SSI达成了一致,能够使得后续UE在需要和网络侧针对网络切片的接入控制等相关情况进行处理时,能够利用SSI来指示网络切片,从而降低了信令的资源消耗,避免了UE与网络侧之间信令资源的浪费,而且还减少了针对网络切片进行接入控制等处理的时延。
实施例二
基于前述实施例相同的发明构思,参见图4,其示出了本发明实施例提供的一种配置网络切片标识的方法,所述方法应用于用户设备UE,所述方法包括:
S401:接收承载有第一类网络切片的NSSAI以及对应的SSI的下行消息;其中,所述NSSAI与对应的SSI均指示相同的网络切片,且所述SSI的长度短于所述NSSAI。
在一种可能的实现方式中,所述方法还包括:
为第二类网络切片的NSSAI设置对应的SSI;其中,所述第二类网路切片包括在已注册的网络切片或为所述UE配置的网络切片中,UE请求为NSSAI设置对应的SSI的网络切片;
向所述网络侧设备发送所述第二类网络切片的NSSAI以及对应的SSI。
在上述实现方式中,相应于仅向接入设备发送所述第二类网络切片的NSSAI以及对应的SSI,则所述第二类网络切片的NSSAI所对应的SSI仅适用于接入层AS;
相应于仅向核心网设备发送所述第二类网络切片的NSSAI以及对应的SSI,则所述第二类网络切片的NSSAI所对应的SSI仅适用于非接入层NAS;
相应于向接入设备和核心网设备发送所述第二类网络切片的NSSAI以及对应的SSI,则所述第二类网络切片的NSSAI所对应的SSI能够适用于AS和NAS。
在上述实现方式中,所述方法还包括:
为未注册的网络切片的NSSAI设置对应的SSI;
向网络侧设备发送所述未注册的网络切片的NSSAI以及所述未注册的网络切片的NSSAI所对应的SSI。
可以理解地,本实施例中,各实现方式的具体阐述如实施例一中所述,本实施例在此不再赘述。
实施例三
基于前述实施例相同的发明构思,参见图5,其示出了本发明实施例提供的一种配置网络切片标识的具体流程,可以包括:
S501:核心网设备将承载有已注册的网络切片或为所述UE配置的网络切片的NSSAI及对应的SSI的下行消息发送至UE;
可以理解地,核心网设备在针对已注册的网络切片或为所述UE配置的网络切片的NSSAI配置完成SSI之后发送给UE,从而实现了网络侧与UE对所支持的网络切片的NSSAI及对应的SSI达成了一致。
S502:UE决定基于上述网络切片的NSSAI及对应的SSI注册或建立协议数据单元(PDU,Protocol Data Unit)会话;
可以理解地,当达成了一致后,后续UE在需要和网络侧针对已注册的网络切片或为所述UE配置的网络切片的接入控制等相关情况进行处理时,能够利用SSI来指示网络切片,从而降低了信令的资源消耗。
S503:UE向所述核心网设备或接入设备发送第二类网络切片的NSSAI以及对应的SSI;
可以理解地,第二类网路切片包括在已注册的网络切片或为所述UE配置的网络切片中,UE请求为NSSAI设置对应的SSI的网络切片。
对于S503的具体阐述参见前述实施例,本实施例对此不再赘述。
