随着第五代移动通信(The 5th Generation,5G)应用的不断发展,网络控制互动服务(Network Controlled Interactive Services,NCIS)业务作为一个新的业务形态被引入到标准中进行相关的标准化业务。NCIS业务主要针对AR/VR、游戏等应用,对速率、时延、丢包率、高速编解码等业务质量有很高的要求。例如:对于VR游戏,需要达到10Gbps速率,丢包率不可超过10E-4。针对NCIS业务建立的会话为NCIS会话,在相同NCIS会话的UE可以认为组成一个NCIS组,例如:游戏中组队。
ProSe包含NCIS,Prose的一个重要场景就是终端至网络(UE-to-network,U2N)中继(relay)的场景。U2N中继是通过一个或多个中继终端为远端终端中继传输数据,从而使远端终端可以与网络实现通信。
图1示出了本申请应用的一种通信系统的示意图。如图1所示,通信系统100主要包括接入与移动管理功能(Access and mobility management function,AMF)101、会话 管理功能(Session Management Function,SMF)102、无线接入网(Radio Access Network,RAN)103、鉴权服务器功能(Authentication Server Function,AUSF)104、统一数据管理(Unified Data Management,UDM)105、策略控制功能(Policy Control function,PCF)106、数据网络(Data Network,DN)107、用户面功能(User Plane Function,UPF)108、用户设备(User Equipment,UE)109。其中,UE 109通过N1接口与AMF 101连接,UE 109通过无线资源控制(Radio Resource Control,RRC)协议与RAN 103连接;RAN 103通过N2接口与AMF 101连接,RAN 103通过N3接口与UPF 108连接;多个UPF 108之间通过N9接口连接,UPF 108通过N6接口与DN 107连接,同时,UPF 108通过N4接口与SMF 102连接;SMF 102通过N7接口与PCF 106连接,SMF 102通过N10接口与UDM 105连接,同时,SMF 102通过N11接口与AMF 101连接;多个AMF 101之间通过N14接口连接,AMF 101通过N8接口与UDM 105连接,AMF 101通过N12接口与AUSF 104连接,同时,AMF 101通过N15接口与PCF 106连接;AUSF 104通过N13接口与UDM 105连接。AMF 101和SMF 102分别通过N8和N10接口从UDM 105获取用户签约数据,通过N15和N7接口从PCF 106获取策略数据。SMF 102通过N4接口控制UPF 108。
RAN 103中可以包括与UE 109进行通信的设备,例如,基站或基站控制器等。应理解,该RAN 103可以与类似于UE 109的任意数目UE通信。每个RAN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(小区)内的终端设备(例如UE)进行通信,RAN 103可以支持不同制式的通信协议,或者可以支持不同的通信模式。可选地,该RAN 103可以是演进型基站(Evolved Node B,eNodeB),或者是无线保真接入点(Wireless Fidelity Access Point,WiFi AP)、或者是全球微波接入互操作性基站(Worldwide Interoperability for Microwave Access Base Station,WiMAX BS),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5G网络中的网络设备或者未来演进的PLMN中的网络设备等。
在一些实施例中,一个AMF 101可以同时服务于多个UE 109。
在一些实施例中,一个SMF 102可以同时服务于多个UE 109。
在一些实施例中,AMF 101可以为UE 109重新选择服务AMF。
在一些实施例中,如图1所示,AMF 101还可以通过N22接口连接网络切片选择功能(Network Slice Selection Function,NSSF)实体。PCF实体106可以通过N5接口连接应用功能(Application Function,AF)实体。
应理解,在UE 109进入空闲态时,可以释放针对该UE 109的RRC连接和N2接口。
在NR系统中,具有临近业务(Proximity-based Services,ProSe)能力的终端设备可以通过PC5接口与具有ProSe能力的另外一个终端设备直接通信。当一个终端设备既可以通过5G网络连接外部数据网络,还具有ProSe能力时,这个终端设备可以充当中继终端(relay UE),另外一个具有ProSe能力的远端终端(remote UE)可以通过PC5接口与中继终端建立直接连接,并通过中继终端与5G网络建立的协议数据单元(Protocol Data Unit,PDU)会话与外部网络交互,其系统架构可以如图2所示。在如图2中,远端终端通过PC5接口连接到中继终端,以及中继终端通过Uu接口连接下一代演进型无线接入网(Next Generation Evolutional Radio Access Network,NG-RAN),从而连接5G核心网(5G Core Network,5GC),5GC通过N6接口连接到应用服务器(application server,AS)。
需要说明的是,图2是以5G通信系统为例进行说明,当然,也可以适用于其他3GPP通信系统,例如4G通信系统,或者未来的3GPP通信系统,本申请对此并不限定。另外,在本申请实施例中,图2中的应用服务器(AS)也可以是其他的终端设备或者外部公共安全互联网。
在一些实施例中,U2N中继的系统架构可以如图3所示。Remote UE和relay UE(层 2 ProSe U2N中继)之间建立PC5链路。为了实现中继通信,在进行中继通信之前,Relay UE和remote UE需要获得必须的配置参数。这些配置参数可以来自PCF实体,应用服务器,预配置在终端上或者用户身份识别模块(Subscriber Identity Module,SIM)卡中。Remote UE在传输数据之前,需要先发现合适的relay UE,并与其建立PC5连接。如图3所示,远端终端可以通过中继终端连接NG-RAN,且NG-RAN可以同时连接远端终端的网元(如AMF、SMF和UPF)和中继终端的网元(如AMF、SMF和UPF)。也即,远端终端通过中继终端连接远端终端的核心网。
在一些实施例中,中继发现(Relay discovery)可以有如下方式:模式A(Model A)(如图4所示)或者模式B(model B)(如图5所示)发现流程。Model A是relay UE主动广播自己可以提供中继服务的中继服务码(Relay service code,RSC);model B是remote UE先发出自己需要的RSC,如果周围有可以支持RSC的relay UE,relay UE就回复remote UE。
发现流程之后,relay UE和remote UE建立PC5连接。
在一些实施例中,多播广播服务(Multicast Broadcast Service,MBS)也被引入5G服务(5G Service,5GS)。临时移动组标识(Temporary Mobile Group Identity,TMGI)用于表示某个多播或广播业务。UE根据应用服务器(Application Server)或核心网配置的MBS信息,从中得到业务对应的TMGI。
为便于更好的理解本申请实施例,对本申请所解决的问题进行说明。
为了实现层2(L2)中继为remote UE中继MBS业务,需要remote UE加入感兴趣的业务。然而,SMF实体不能获知remote UE是否通过relay UE接入网络,也就不能合理分配单播或者多播资源。
基于上述问题,本申请提出了一种中继通信的方案,网络设备可以确定针对远端设备的数据的传输方式,且传输方式可以为单播/多播方式,也可以是单播方式,从而,满足不同的业务需求,优化中继通信。
以下通过具体实施例详述本申请的技术方案。
图6是根据本申请实施例的中继通信的方法200的示意性流程图,如图6所示,该中继通信的方法200可以包括如下内容中的至少部分内容:
