通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如设备到设备(Device to Device,D2D)通信、机器到机器(Machine to Machine,M2M)通信、机器类型通信(Machine Type Communication,MTC)、以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
可选地,本申请实施例中的通信系统也可以应用于载波聚合(Carrier Aggregation,CA)场景、双连接(Dual Connectivity,DC)场景、独立(Standalone,SA)布网场景等。
图1是本申请实施例应用的一种可能的无线通信系统的示意图。该无线通信系统100可以包括接入网设备110。接入网设备110可以是与终端设备通信的设备。
接入网设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。接入网设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、未来网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
通信系统100还包括位于接入网设备110覆盖范围内的至少一个终端设备120。
终端设备120可以是移动的或固定的。可选地,终端设备120可以指用户设备、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等,本申请实施例对此并不限定。其中,可选地,终端设备120之间也可以进行终端直连(Device to Device,D2D)通信。

通信系统100还包括与接入网设备110进行通信的核心网设备130。
核心网设备130可以是5G系统的核心网设备。例如,接入与移动性管理功能(Access and Mobility Management Function,AMF),负责接入和移动性管理,具有对用户进行认证、切换、位置更新等功能;又例如,会话管理功能(Session Management Function,SMF),负责会话管理,包括分组数据单元(Packet Data Unit,PDU)会话的建立、修改、释放等;又例如,用户面功能(User Plane Function,UPF),负责用户数据的转发。可选地,核心网设备130也可以为LTE系统或其他系统的核心网设备。

通常,终端设备在注册或者注册更新时,会将自己的能力信息上报给接入网设备,继而接入网设备将终端设备的能力信息发送到核心网设备,并由核心网设备进行保存。当终端设备发起RRC连接建立请求时,接入网设备会向核心网设备请求该终端设备的能力信息,从而根据该终端设备的能力信息为终端设备提供配置。
随着终端设备支持的特性越来越多,终端设备的能力信息也会越来越多,这就产生了巨大的信令开销。同时,核心网设备需要保存所有终端设备注册的能力信息,这给核心网也带来了较大的挑战。
为此,可以将终端设备支持的能力信息集合与能力标识关联起来,通过能力标识来实现能力信息集合的指示,从而减少能力信息上报和存储所带来的信令开销。其中,终端设备的能力标识可以由运营商来分配。
为了实现能力标识的分配,本申请实施例提供了一种分配能力标识的方法,网络设备能够有效地为终端设备分配能力标识。
本申请实施例中,网络设备可以通过非接入层(Non-Access Stratum,NAS)过程中向终端设备发送该能力标识,或者通过无线资源控制(Radio Resourese Control,RRC)过程向终端设备发送该能力标识。该网络设备例如可以是核心网设备或接入网设备。该核心网设备例如可以是AMF。该接入网设备例如可以是gNB。
例如,核心网设备可以在NAS过程或者RRC过程中向终端设备发送能力标识,接入网设备可以在NAS过程中向终端设备发送该能力标识。
应理解,在NAS过程中发送该能力标识,可以指该能力标识通过NAS消息发送给终端设备,即,该能力标识封装在NAS消息中。在RRC过程中发送该能力标识,可以指该能力标识通过RRC消息发送给终端设备,该能力标识封装在RRC消息中。
本申请实施例对终端设备的能力信息不做任何限定。例如,该能力信息可以是终端设备的无线能力(Radio Capability)、公共陆地移动网络(Public Land Mobile Network,PLMN)能力信息、系统能力信息,频带能力信息,频带组合能力信息、终端类型能力信息等等。
图2和图3是本申请实施例的分配能力标识的方法的流程交互图。图2和图3所示的方法可以由终端设备、接入网(Radio Access Network,RAN)设备、核心网(Core Net,CN)或者UE能力管理功能(UE Capability Management Function,UCMF)实体等网络实体执行。该终端设备例如可以为图1中所示的终端设备120;该核心网设备例如可以是图1中所示的核心网设备130;该接入网设备例如可以是图1中所示的接入网设备110。
如图2所示,终端设备在NAS过程中获取网络为其分配的能力标识。该分配能力标识的方法200包括以下步骤中的部分或全部。
在210中,核心网设备获取能力标识。
该能力标识可以是核心网设备为终端设备分配的,也可以是UCMF实体为终端设备分配的。
其中,所述能力标识用于标识所述终端设备的能力信息,且所述能力标识在NAS过程或RRC过程中发送至所述终端设备。
当由UCMF实体为终端设备分配能力标识时,可选地,核心网设备可以向UCMF实体发送能力标识请求消息,其中,该能力标识请求消息用于指示该UCMF实体为终端设备分配能力标识;响应于该能力标识请求消息,UCMF实体向核心网设备发送该UCMF实体为终端设备分配的该能力标识;核心网设备接收UCMF实体发送的该能力标识。
在220中,核心网设备向接入网设备发送N2消息。
其中,该N2消息中携带NAS消息。该NAS消息中携带能力标识,即该能力标识封装在该NAS消息中。该NAS消息例如可以是注册请求消息、注册接受消息、注册更新消息等。
在230中,接入网设备接收核心网设备发送的该N2消息。
在240中,接入网设备向终端设备发送RRC消息。
其中,该RRC消息中携带该NAS消息。
具体地,接入网设备接收到N2消息后,从中获取该NAS消息,并将该NAS消息封装在RRC消息中,并向终端设备发送携带该NAS消息的RRC消息。
在250中,终端设备接收接入网设备发送的RRC消息。
终端设备从该RRC消息中获取来自核心网设备的NAS消息,并从该NAS消息中获取该能力标识。
如图3所示,终端设备在RRC过程中获取网络为其分配的能力标识。该分配能力标识的方法300包括以下步骤中的部分或全部。
在310中,核心网设备获取能力标识。
核心网设备在310中获取能力标识的过程可以参考图2中的步骤210的相关描述,为了简洁,这里不再赘述。
在320中,核心网设备向接入网设备发送N2消息。
其中,该N2消息中携带该能力标识。
在330中,接入网设备接收核心网设备发送的该N2消息。
在340中,接入网设备向终端设备发送RRC消息。
其中,该RRC消息中携带该能力标识。
具体地,接入网设备接收到N2消息后,获取N2消息中的该能力标识,并将该能力标识封装在RRC消息中,并且向终端设备发送携带该能力标识的RRC消息。
因此,网络设备通过在NAS过程或RRC过程中为终端设备发送能力标识,使得终端设备在NAS过程或RRC过程中获取网络侧为其分配的能力标识。终端设备和网络设备可以将该能力标识与终端设备上报的能力信息相关联,从而通过该能力标识来指示终端设备支持的能力,减少了能力信息上报和存储所带来的信令开销。
在图2所示的方法200中,终端设备是在NAS过程中获取该能力标识,即终端设备通过NAS消息获取该能力标识。核心网设备将该能力标识封装在该NAS消息中,并将该NAS消息发送给终端设备。终端设备从该NAS消息中获取该能力标识。
应理解,NAS消息为核心网和终端设备之间传输的消息。在NAS消息的传输过程中,核心网设备可以将NAS消息封装在N2消息中发送给接入网设备,该接入网设备从N2消息中获取该NAS消息后,该接入网设备可以将该NAS消息封装在RRC消息中发送给终端设备。其中,N2消息为核心网设备和接入网设备之间传输的消息,RRC消息为接入网设备和终端设备之间传输的消息。接入网设备仅仅转发该NAS消息,无法获取该NAS消息中携带的该能力标识。
而在图3所示的方法300中,终端设备在RRC过程中获取该能力标识,即终端设备通过RRC消息获取该能力标识。核心网设备将该能力标识发送给接入网设备,接入网设备接收到该能力标识后,会将该能力标识封装在RRC消息中发送给终端设备。终端设备接收到该RRC消息后,从该RRC消息中获取该能力标识。
网络设备为终端设备分配的能力标识用于标识终端设备的能力信息。不同的能力标识可以用于指示终端设备支持的不同的能力集合。因此,终端设备和网络设备不仅需要知道网络设备为终端设备分配的能力标识,还需要知道终端设备支持的能力。
可选地,该方法还包括:
接入网设备向终端设备发送能力请求消息;
终端设备接收接入网设备发送的该能力请求消息;
响应于该能力请求消息,终端设备向接入网设备发送其能力信息;
接入网设备接收终端设备发送的该能力信息。
其中,该能力请求消息用于指示终端设备上报该终端设备的能力。
接入网设备例如可以根据过滤信息(filter),确定需要终端设备上报的能力,并通过该能力请求消息指示终端设备上报需要其上报的能力。也就是说,该过滤信息用于在各种能力中过滤出网络设备需要终端设备上报的能力。
接入网设备可以从UCMF或核心网设备获得该过滤信息。
在核心网设备没有向UCMF实体请求能力标识时,UCMF可以仅向该核心网设备发送过滤信息, 而能力标识由核心网设备来分配;或者,核心网设备也可以向UCMF请求获取过滤信息和能力标识,UCMF为该终端设备分配能力标识,并向该核心网设备发送过滤信息和能力标识。核心网设备将该过滤信息发送给接入网设备,从而接入网设备可以根据该过滤信息,向终端设备发送该能力请求消息,以指示终端设备上报相应的能力信息。
另外,对于接入网设备而言,接入网设备可以从核心网设备获取该能力标识,也可以从终端设备获取该能力标识。接入网设备可以在上述能力标识分配的过程中获取该能力标识,也可以在后续需要使用时再从核心网设备获取该能力标识。
终端设备、核心网设备、接入网设备和UCMF实体在获取该能力标识以及终端设备的能力信息后,对终端设备上报的该能力信息与该能力标识进行关联,即建立能力信息和能力标识之间的对应关系,并将该对应关系存储下来。
例如,接入网设备接收终端设备发送的该能力信息后,将该能力信息发送给核心网设备,核心网设备接收该能力信息,并将该能力信息与该能力标识进行关联,并且存储关联后的该能力信息与该能力标识。
又例如,核心网设备在获取该能力信息后,向UCMF实体发送该终端设备的能力信息,UCMF实体接收该能力信息,并存储该能力信息与该能力标识,从而对该能力信息与该能力标识进行管理。此外,如果终端设备的该能力标识是核心网设备分配的,那么核心网设备还可以将该能力标识发送给该UCMF实体。
应理解,核心网设备发送能力请求消息以及终端设备上报能力信息,可以发生在图2和图3中任何步骤之前或之后。例如,接入网设备可以先从该终端设备获取该终端设备的能力信息,再将能力标识发送给终端设备;接入网设备也可以先将能力标识发送给终端设备,再从该终端设备获取该终端设备的能力信息。这里均不做限定。
经过上述过程,终端设备、接入网设备、核心网设备和UCMF可以获取终端设备上报的能力信息与为该终端设备分配能力标识之间的对应关系,通过该能力标识来指示该能力信息,从而减少能力信息上报和存储所带来的信令开销。
核心网设备从UCMF获取该能力标识或者该核心网设备为终端设备分配能力标识后,该核心网设备一方面要发送该能力标识,另一方面要接收终端设备的能力信息。本申请实施例对核心网设备接收能力信息和发送能力标识的顺序不做限定。
例如,核心网设备可以先向终端设备发送携带能力标识的NAS消息,后接收接入网设备发送的该终端设备的能力信息;也可以在接收到该终端设备的能力信息后,再向终端设备发送携带该能力标识的NAS消息。
类似地,UCMF实体为终端设备分配能力标识后,UCMF实体也需要发送该能力标识以及接收终端设备的能力信息。本申请实施例对UCMF实体接收能力信息和发送能力标识的顺序也不做限定。
例如,核心网设备可以在获取终端设备的能力信息后,将该能力信息发送给UCMF实体,并向UCMF实体请求该能力标识。从而UCMF实体在接收到该能力信息后,向核心网设备发送该UCMF实体为终端设备分配的该能力标识。
又例如,核心网设备也可以先向UCMF实体请求该能力标识,并在将该能力标识传递至终端设备后,再将终端设备的该能力信息发送给UCMF实体。
本申请实施例中,所述NAS过程例如包括注册过程和配置更新等过程,所述RRC过程例如包括RRC重配置过程、能力信息获取过程和RRC消息传输等过程。
例如,图2中的该NAS消息可以是注册接受完成消息,该注册接受完成消息中携带该能力标识。
其中,终端设备可以向接入网设备发送注册请求消息;响应于该注册请求消息,接入网设备向终端设备发送该注册接受消息;终端设备接受该注册接受消息。其中,该注册接受消息中封装有该能力标识。
可选地,该方法还包括:响应于该注册接受消息,终端设备向接入网设备发送注册接受完成消息(Registration accept complete);接入网设备接收终端设备发送的该注册接受完成消息;接入网设备将该注册接受完成消息转发给核心网设备;核心网设备接收该接入网设备发送的该注册接受完成消息。
可选地,该注册接受完成消息中可以携带该能力标识。
又例如,图2中的该NAS消息可以是配置更新命令,该配置更新命令中携带该能力标识。
可选地,该方法还包括:
响应于该配置更新命令,终端设备向接入网设备发送配置更新完成消息(UE Configuration Update Complete);
接入网设备接收终端设备发送的该配置更新完成消息;
接入网设备将该配置更新完成消息转发给核心网设备;
核心网设备接收接入网设备发送的该配置更新完成消息。
可选地,该配置更新完成消息中携带该能力标识。
又例如,图3中的该RRC消息可以是能力请求消息,该能力请求消息中携带该能力标识。
可选地,该方法还包括:响应于该能力请求消息,终端设备向接入网设备发送该终端设备的能力信息;接入网设备接收终端设备发送的其能力信息。
可选地,该方法还包括:终端设备向接入网设备发送RRC消息,该RRC消息中同时包括该能力信息和该能力标识。
下面结合图4至图8,分别对终端设备如何在这几个过程中获取能力标识进行具体描述。
其中,图4和图5是终端设备从NAS消息中获取能力标识的方法的流程交互图,图6至图8是终端设备从RRC消息中获取能力标识的方法的流程交互图。
图4至图8中示出了终端设备、接入网设备、核心网设备和UCMF实体。
如图4所示,网络设备在注册过程中为终端设备分配能力标识。本申请实施例的方法可以包括图4中的部分或者全部步骤:
401,终端设备向接入网设备发送RRC建立请求消息(RRC Setup Request)。
402,响应于该RRC建立请求消息,接入网设备向终端设备发送RRC建立消息(RRC Setup)。
403,终端设备向接入网设备发送RRC建立完成消息(RRC Setup Complete)。
该RRC建立完成消息中携带注册请求消息(Registration Request)。
终端设备还可以在403中上报用于指示是否支持网络设备分配能力标识的指示信息,该指示信息可以封装在NAS消息例如注册请求消息或注册更新消息中;该指示信息也可以封装在RRC建立完成消息中。
404,接入网设备向核心网设备发送N2消息。
该N2消息例如为初始UE信息(INITIAL UE MESSAGE)。
接入网设备为该终端设备建立N2连接,并在N2消息中携带在403中接收到的注册请求消息,并将该N2消息发送给核心网设备。如果用于指示是否支持网络设备分配能力标识的该指示信息携带于RRC建立完成消息中,则接入网设备将该指示信息也携带在该N2消息中。
接下来执行405或者406。
核心网设备接收到来自终端设备的注册请求消息之后,如果核心网设备此时没有获取终端设备能力的过滤信息,则执行步骤405或者406。
405,核心网设备从UCMF实体获取能力标识和过滤检索(filter retrieve)信息(简称为过滤信息)。
具体地,核心网设备可以向UCMF实体发送用于请求能力标识和过滤信息的请求消息,其中携带终端设备的标识(UE Identify,UE ID)。UCMF根据该请求消息向核心网设备发送该过滤信息和该能力标识,其中携带该UE ID。
406,核心网设备从UCMF获取过滤信息。
具体地,核心网设备可以向UCMF实体发送用于请求过滤信息的请求消息,其中携带UE ID。UCMF根据该请求消息向核心网设备发送该过滤信息,其中携带该UE ID。
如果执行405,UCMF为终端设备分配能力标识,并将该能力标识和过滤信息发送给核心网设备。
如果执行406,则由核心网设备为终端设备分配能力标识,核心网设备从UCMF获取过滤信息。
407,核心网设备向接入网设备发送N2消息。
其中,该N2消息中携带NAS消息,该NAS消息例如为注册接受消息(Registration accept)。其中,该能力标识封装在该注册接受消息中,该能力标识作为该NAS消息的一部分进行传输。
该N2消息中还携带该过滤信息。
可选地,该N2消息中还携带该能力标识。此时,应注意,该N2消息携带的该能力标识是用于发送给接入网设备的。该能力标识与注册接受消息都封装在N2消息中。而该注册接受消息中也封装相同的该能力标识,且该注册接受消息中封装的该能力标识是用于发送给终端设备的。
408,接入网设备根据该过滤消息执行过滤(Enforce filter)。
接入网设备可以根据该过滤信息,确定终端设备需要上报的能力信息。
