Description

无线通信方法、网络节点和终端设备 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及无线通信方法、网络节点和终端设备。
背景技术
在长期演进(Long Term Evolution,LTE)和新空口(New Radio,NR)系统中,通常会部署公共网络系统,即基于公共陆地移动网络(Public Land Mobile Network,PLMN)。但是在一些场景中,例如在办公场景,家庭场景,工厂中,为了能够更加有效安全的管理,通常会有当地的用户或者管理者布局本地网络。本地网络组中的成员通信时可以采用点到点的通信方式或者点到多点的通信方式。当终端设备加入到一个本地网络组中进行数据通信时,网络会给终端设备分配一个内部的地址,此地址是针对服务于终端设备的用户面功能(User Plane Function,UPF)的。
但是,当终端设备的服务UPF发生更改时,为所述终端设备分配的地址也会发生变化,导致终端设备需要更新与本地网络的连接以实现地址更换的目的,而这种实现方式导致组通信的业务将会中断。
发明内容

第六方面,提供了一种终端设备,包括处理器和存储器。所述存储器用于存储计算机程序,所述处理器用于调用并运行所述存储器中存储的计算机程序,以执行上述第二方面或其各实现方式中的方法。
第七方面,提供了一种芯片,用于实现上述第一方面至第二方面中的任一方面或其各实现方式中的方法。具体地,所述芯片包括:处理器,用于从存储器中调用并运行计算机程序,使得安装有所述芯片的设备执行如上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第八方面,提供了一种计算机可读存储介质,用于存储计算机程序,所述计算机程序使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统或5G系统等。
本申请实施例提到的终端设备包括但不限于经由有线线路连接,如经由公共交换电话网络(Public Switched Telephone Networks,PSTN)、数字用户线路(Digital Subscriber Line,DSL)、数字电缆、直接电缆连接;和/或另一数据连接/网络;和/或经由无线接口, 如,针对蜂窝网络、无线局域网(Wireless Local Area Network,WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器;和/或另一终端设备的被设置成接收/发送通信信号的装置;和/或物联网(Internet of Things,IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话;可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System,PCS)终端;可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System,GPS)接收器的PDA;以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、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。接入终端可以是蜂窝电话、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、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
本申请实施例提到的接入网设备可以是与终端设备(或称为通信终端、终端)通信的设备。网络设备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。可选地,该网络设备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移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的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。
本申请实施例提到的核心网设备可以是5G核心网设备。例如,可以为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,可以为会话管理功能(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,可以为用户面功能(user plane function,UPF),负责用户数据的转发。其中,核心网设备还可以为LTE系统或其他系统的核心网设备。
可选地,本申请实施例可以应用于本地网络和公共陆地网络。
其中,公共陆地网络可以为基于PLMN的公共陆地网络。
本地网络也可以称为本地局域网络或私有网络,该本地网络通常布置在办公场景,家庭场景,工厂中,可以实现更加有效安全的管理,通常会有当地的用户或者管理者布局本地网络。通常,授权的能够接入的用户具有接入到本地网络的权限。
本地网络可以由公共陆地网络所管理或管辖,但是也可以不由公共陆地网络或管理或管辖。
可选地,本地网络可以采用非授权频段进行通信,或者也可以与公共陆地网络共享授权频段。
可选地,本地网络可以是属于3GPP范畴的网络。其中,该本地网络的核心网可以是NR技术或LTE技术的核心网,以及本地网络可以通过NR接入网、LTE接入网或无线保真(Wireless Fidelity,WiFi)接入到核心网。
可选地,在本申请实施例中,公共陆地网络与本地网络可以共用核心网,而接入网是独立的;或者,可以共用接入网,而核心网是独立的;或者,可以共用接入网以及核心网;或者,接入网和核心网均不共用。在通信系统中,通常会部署公共网络系统,例 如基于公共陆地移动网络(public land mobile network,PLMN)的网络系统。但是在公共网络系统中,当第一终端设备与第二终端设备之间进行通信时,数据包不仅需要经过3GPP网络内部的节点,还需要经过3GPP网络外部的DNS对数据的解析路由,才能够到达第二终端设备,通信时延较长。
鉴于此,本申请实施例提供了一种点到点的通信方式,使得数据包在发送过程中,仅在3GPP网络内部节点间进行路由便可到达第二终端设备。
数据在3GPP内部传输能够降低传输时延,内部传输指数据仅在3GPP内部网络节点无线接入网(radio access network,RAN),AMF和/或SMF间进行路由,数据不经过外部的DNS的解析路由过程。
本申请实施例可以应用于公共陆地移动网络,也可以用于本地网络。
其中,公共陆地网络可以为基于PLMN的公共陆地网络。
本地网络也可以称为本地局域网络或私有网络,该本地网络通常布置在办公场景,家庭场景,工厂中,可以实现更加有效安全的管理,通常会有当地的用户或者管理者布局本地网络。通常,授权的能够接入的用户具有接入到本地网络的权限。
本地网络可以由公共陆地网络所管理或管辖,但是也可以不由公共陆地网络或管理或管辖。
可选地,本地网络可以采用非授权频段进行通信,或者也可以与公共陆地网络共享授权频段。
可选地,本地网络可以是属于3GPP范畴的网络,可以包括接入网和核心网。其中,该本地网络的核心网可以是NR或LTE的核心网,以及本地网络可以通过NR接入网、LTE接入网或无线保真(Wireless Fidelity,WiFi)接入到核心网。
可选地,在本申请实施例中,公共陆地网络与本地网络可以共用核心网,而接入网是独立的;或者,可以共用接入网,而核心网是独立的;或者,可以共用接入网以及核心网;或者,接入网和核心网均不共用。
例如,在LTE和NR系统中,可以部署公共网络系统,即基于PLMN的公共陆地网络。
但是,在一些场景中,例如在办公、家庭、工厂等场景中,为了能够更加有效安全的管理,通常会有当地的用户或者管理者布局本地网络。本地网络组中的成员通信时可以采用点到点的通信方式或者点到多点的通信方式。当终端加入到一个组中进行数据通信时,网络会给终端分配一个内部的地址,此地址是针对服务于终端设备的UPF的。
当终端设备的服务UPF发生更改时,所述终端设备的地址也会发生变化,导致所述终端设备需要更新与网络的连接实现地址更换的目的。这种实现方式导致组通信的业务将会中断。
图1是本申请实施例提供的点到点的通信方式的架构图。该通信方式使得终端设备的服务UPF发生更改时,能够避免组通信的业务将会中断。具体地,针对每个本地网络组通信,配置一个锚(anchor)UPF,当组成员(即终端设备)加入组时,组成员连接的端点是此anchor UPF。
如图1所示,本地网络组可以包括4个UE(UE1、UE2、UE3、UE4)和4个UPF(UPF1、UPF2、UPF3、UPF4)。其中,UPF1为直接服务于UE1的变更前的UPF,UPF2为直接服务于UE1的变更后的UPF,UPF3为直接服务于UE3的UPF,UPF4为直接服务于UE4的UPF。
进一步地,所述anchor UPF可以与UPF1、UPF2、UPF3、UPF4中的至少一个建立通道。例如,通信分组无线服务用户面隧道协议(General Packet Radio Service tunneling protocol for user plane,GTP-U)通道或者互连网的协议(Internet Protocol,IP)隧道。
本申请实施例中,假设直接服务于UE1的UPF1连接到anchor UPF且直接服务于UE3的UPF3连接到anchor UPF,即建立UPF1到anchor UPF的通道以及UPF3到anchor  UPF的通道。
当UE1需要给组中的UE3发送数据时,UE1先将数据发送给UPF1,UPF1根据预先建立的通道将数据发送给anchor UPF,anchor UPF将数据根据预先建立的通道发送给直接服务于UE3的UPF3,进而由UPF3转发给UE3。
可选地,本申请实施例中,直接服务于UE的UPF和anchor UPF之间的通道可以由核心网的5GLAN连接管理实体建立,例如可以由会话管理功能(Session Management Function,SMF)建立。
如图1所示,假设服务于UE1的UPF1需要切换至UPF2时,由于网络为所述终端设备分配的地址(anchor UPF的地址)不需要改变,因此能够保持组通信的业务连续性。
应理解,本申请实施例中的直接服务于UE的UPF可以指UE和UPF之间建立有通道。例如,直接服务于UE1的UPF可以指UE1和UPF1之间建立有通道。所述通道可以用于传输数据。
还应理解,在其他可替代实施例中,所述本地网络组还可以称为局域网(LAN)组。例如,5G LAN组。所述终端设备也可以称为用户设备(User Equipment,UE)。
图2示出了根据本申请实施例的无线通信的方法200的示意性流程图,该方法200可以由核心网络节点执行。例如,可以由会话管理功能(Session Management Function,SMF)执行。应理解,图2所示的方法可应用于本地网组,所述本地网组包括直接服务于多个终端设备的多个网络节点和用于连接所述多个网络节点的第一网络节点。例如,所述第一网络节点可以为图1所示的锚UPF,所述多个网络节点可以包括图1所示的UPF1、UPF2、UPF3、UPF4。
如图2所示,该方法200包括:
S210,核心网络节点将服务于第一终端设备的第一通道切换至第二通道;或者说,所述第一终端设备通过核心网络节点将服务于所述第一终端设备的第一通道切换至第二通道;其中,所述第一通道为所述第一网络节点和所述多个网络节点中的第二网络节点之间的通道,所第二通道为所述第一网络节点和所述多个网络节点中的第三网络节点之间的通道。
例如,所述第二网络节点为直接服务于所述第一终端设备的变更前的网络节点,所述第三网络节点为直接服务于所述第一终端设备的变更后的网络节点。
即,所述核心网络节点将服务于所述第一终端设备的变更前的第二网络节点和所述第一网络节点之间的通道切换为服务于所述第一终端设备的变更后的第三网络节点和所述第一网络节点之间的通道,由此,直接服务于所述第一终端设备的网络节点为第二网络节点时,所述第一终端设备可以根据所述第一网络节点的地址通过所述第一通道与所述本地网络组建立连接,直接服务于所述第一终端设备的网络节点为第三网络节点时,所述第一终端设备可以根据所述第一网络节点的地址通过所述第二通道与所述本地网络组建立连接。
换句话说,不管直接服务于所述第一网络设备的网络节点是否发生变更,所述第一终端设备用于接入所述本地网络组的所述第一网络节点的地址可以是同一个地址。
也就是说,当直接服务于终端设备的网络节点由第二网络节点切换为第三网络节点时,直接通过核心网络节点将服务于第一终端设备的第一通道切换至第二通道即可,并不需要对所述核心网络节点为所述终端设备分配的用于接入本地网络的所述第一网络节点的地址进行更新,进而能够保持业务的连续性。
下面对本申请实施例中所述核心网络节点将服务于所述第一终端设备的通道由所述第一通道切换至所述第二通道的实现方式进行说明。
可选地,在本申请的一些实施例中,所述核心网络节点建立所述第二通道;所述核心网络节点通过所述第二通道收到所述第三网络节点发送的第一通知信息时,将服务于所述第一终端设备的所述第一通道切换至所述第二通道,所述第一通知信息用于通知所 述核心网络节点所述第三网络节点已收到第一终端设备发送的数据。
也就是说,所述核心网络节点首先建立所述第二通道,所述核心网络节点通过所述核心通道接收到所述第三网络设备发送的所述第一通知信息时,将服务于所述第一终端设备的通道由所述第一通道切换为所述第二通道。
本申请实施例中,就所述第三网络设备而言,所述第三网络设备需要在核心网络节点建立好所述第二通道之后,生成所述第一通知信息。应当理解,所述第一通知信息可以是所述第一终端设备在所述核心网络节点建立好所述第二通道之后生成的信息,也可以是所述第一终端设备在所述核心网络节点建立好所述第二通道之前生成的信息,本申请实施例对此不做具体限定。
例如,所述第一终端设备接收到所述第一终端设备发送的数据时,生成所述第一通知信息,然后,所述第一终端设备等待所述第二通道建立完成或者直接在建立完成的所述第二通道上发送所述第一通知信息。
图3是本申请实施例的无线通信方法的示意性流程图。图3所示的方法可应用于本地网组,所述本地网组包括直接服务于多个终端设备的多个网络节点和用于连接所述多个网络节点的第一网络节点。所述多个终端设备可以包括图3所示的第一终端设备,所述多个网络节点可以包括直接服务于所述第一终端设备的第三网络节点。例如,图3所示的核心网络节点可以由会话管理功能(Session Management Function,SMF),所述第一网络节点可以为图1所示的锚UPF,所述第一终端设备为图1所示的UE1,第二网络节点可以为图1所示的UPF1,所述第三网络节点可以为图1所示的UPF2。

换句话说,所述第一终端设备确定直接服务于所述第一终端设备的网络节点发生变更时,通过核心网络节点将服务于所述第一终端设备的第一通道切换至第二通道。
进一步地,在S330中,所述第三网络节点在生成所述第一通知信息时,需要确定已经接收到的数据中包括所述第一终端设备发送的数据。

由此,所述第一终端设备在接收到所述第一终端设备的数据时,可以基于已经接收到的数据中携带的地址信息,确定已经接收到的数据中是否包括所述第一终端设备发送的数据。
在具体实现中,所述核心网络节点向所述第三网络节点发送所述第一终端设备的地 址信息,可以在建立所述第二通道的过程中,向所述第三网络节点发送所述第一终端设备的地址信息。
应理解,图3所示的实施例是由第一终端设备触发第三网络节点生成第一通知信息,进而通过所述第一通知信息触发所述核心网络节点切换服务于所述第一终端设备的通道。但本申请实施例不限于此。例如,在其他可替代实施例中,可以由所述第一网络节点向所述核心网络节点发送第二通知信息,所述第二通知信息用于触发所述核心网络节点切换服务于所述第一终端设备的通道。
具体地,所述核心网络节点收到所述第一网络节点发送的第二通知信息时,将服务于所述第一终端设备的所述第一通道切换至所述第二通道,所述第二通知信息用于通知所述核心网络节点所述第一网络节点已收到所述第一终端设备发送的数据。
也就是说,由第一终端设备触发第一网络节点生成第二通知信息,进而通过所述第二通知信息触发所述核心网络节点切换服务于所述第一终端设备的通道。

换句话说,所述第一终端设备确定直接服务于所述第一终端设备的网络节点发生变更时,通过核心网络节点将服务于所述第一终端设备的第一通道切换至第二通道。
进一步地,在S430中,所述第一网络节点在生成所述第二通知信息时,需要确定已经接收到的数据中包括所述第一终端设备发送的数据。
可选地,在本申请的一些实施例中,所述第一网络节点可以预先存储有所述第一终端设备的地址信息,进而根据所述第一终端设备的地址信息在已经接收到的数据中确定是否包括所述第一终端设备发送的数据。
应理解,图3和图4所示的方法仅为本申请实施例的示例,不应理解为对本申请实施例的限定。例如,所述第一网络节点或所述第三网络节点确定已接收的数据中是否包括所述第一终端设备发送的数据时,可以不局限于根据所述第一终端设备的地址信息确定。
例如,在其他可替代实施例中,所述第一网络节点或所述第三网络节点可以根据接 收数据的通道确定已经接收到的数据中是否包括所述第一终端设备的数据。
