为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本发明。在本申请实施例中所使用的单数形式的“一种”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。
应当理解,本文中使用的术语“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。
取决于语境,如在此所使用的词语“如果”、“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地,取决于语境,短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
还需要说明的是,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的商品或者***不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种商品或者***所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括要素的商品或者***中还存在另外的相同要素。
本申请实施例提供的技术方案可以适用于多种***,尤其是5G***。例如适用的***可以是全球移动通讯(Global System Of Mobile Communication,GSM)***、码分多址(Code Division Multiple Access,CDMA)***、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(General Packet Radio Service,GPRS)***、长期演进(Long Term Evolution,LTE)***、LTE频分双工(Frequency Division Duplex,FDD)***、LTE时分双工(Time Division Duplex,TDD)***、高级长期演进(Long Term Evolution Advanced,LTE-A)***、通用移动***(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability For Microwave Access,Wimax)***、5G新空口(New Radio,NR)***等。这多种***中均包括终端设备和网络设备。***中还可以包括核心网部分,例如演进的分组***(Evloved Packet System,EPS)、5G***(5GS)等。
本申请实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的***中,终端设备的名称可能也不相同,例如在5G***中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机, 例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为***、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端设备(Remote Terminal)、接入终端设备(Access Terminal)、用户终端设备(User Terminal)、用户代理(User Agent)、用户装置(User Device),本申请实施例中并不限定。
本申请实施例涉及的网络设备,可以是基站,该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本申请实施例涉及的网络设备可以是全球移动通信***(Global System For Mobile Communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-Band Code Division Multiple Access,WCDMA)中的网络设备(Nodeb),还可以是长期演进(Long Term Evolution,LTE)***中的演进型网络设备(Evolutional Node B,Enb或E-Nodeb)、5G网络架构(Next Generation System)中的5G基站(Gnb),也可以是家庭演进基站(Home Evolved Node B,Henb)、中继节点(Relay Node)、家庭基站(Femto)、微微基站(Pico)等,本申请实施例中并不限定。在一些网络结构中,网络设备可以包括集中单元(Centralized Unit,CU)节点和分布单元(Distributed Unit,DU)节点,集中单元和分布单元也可以地理上分开布置。
本申请实施例涉及的网络设备,具体可以是采用CU-DU分离架构。图1为CU-DU分离架构的示意图,如图1所示,CU和DU在物理上可以是分离的,也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU。CU和DU之间可以通过接口相连,例如可以是通过F1接口连接。CU和DU可以根据无线网络的协议层划分。例如RRC(Radio Resource Control,无线资源控制层)、业务数据适配协议栈(Service Data Adaptation Protocol,SDAP)以及分组数据汇聚层协议(Packet Data Convergence Protocol,PDCP)层的功能设置在CU,而无线链路控制(Radio Link Control,RLC),媒体接入控制(Media Access Control,MAC)层,物理(Physical,PHY)层等的功能设置在DU。可以理解,对CU和DU处理功能按照这种协议层的划分仅仅是一种举例,也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如,CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中,将RLC层的部分功能和RLC层以上的协议层的功能设置在CU,将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中,还可以按照业务类型或者其他***需求对CU或者DU的功能进行划分。例如按时延划分,将处理时间需要满足时延要求的功能设置在DU,不需要满足该时延要求的功能设置在CU。在另一种设计中,CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置,也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能,也可以将射频功能拉远设置。
图2为现有技术中处于RRC非活跃态的终端设备进行数据传输的示意图,如图2所示,处于RRC非活跃态的终端设备UE首先向DU发送携带UE上下文标识(例如I-RNTI)的RRC连接恢复请求,由DU向CU发送携带有该UE上下文标识的接入请求,然后,CU基于该接入请求与DU建立UE上下文,由此,终端设备恢复至RRC连接态,最后,终端设备、DU以及CU进行上下行数据传输。其中,DU与CU之间的上行数据传输过程包括:DU对上行数据进行数据处理,并将处理后的数据发送至CU。
现有技术中,在CU与DU建立UE上下文之前,DU未保留有终端设备对应的UE上下文,导致DU无法对上行数据进行处理。在CU与DU建立UE上下文之后,DU可以根据建立的UE上下文完成对上行数据的处理。因此,现有技术中,CU与DU建立UE上下文成为上行数据传输过程中的关键。
然而,对于小数据传输场景,例如物联网数据传输场景,上行数据的数量和规格都较小,若每次传输上行数据都需要先建立CU与DU的UE上下文,会导致数据传输过程较为繁琐,效率较低。
例如,对于智能水表等设备,其对应的上行数据仅包括用水数据以及设备健康状态数据等,该上行数据可以通过一个或者少量的上行数据包进行传输,且该设备不具有期望的下行数据。在这种情况下,会使得现有的上行数据传输方式存在过程繁琐、效率低下的问题。另外,在设备数量较多时,若需要进行锚点转移或者路径转换等操作,也会造成大量的信令开销,从而导致网络资源的浪费。
本申请实施例提供了一种上行数据处理方法、装置、网络设备、终端设备及介质,用以解决现有技术存在的技术问题。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不做赘述。
图3为本申请实施例提供的上行数据处理方法的示意图,如图3所示,上行数据处理方法具体包括以下步骤:
S1、在处于无线资源控制RRC非活跃态时,终端设备向第一分布单元DU发送第一消息和上行数据。
其中,第一消息用于请求进行RRC恢复。第一DU为终端设备对应的服务DU,第一DU对应的第一CU为终端设备对应的服务CU。
S2、第一DU接收处于无线资源控制RRC非活跃态的终端设备UE发送的第一消息,并对上行数据进行数据处理,得到第一处理数据。
具体的,第一DU根据所述终端设备对应的UE上下文对上行数据进行L2(层2)处理,即MAC、RLC层的数据处理,从而得到第一处理数据。
S3、第一DU将第一处理数据发送至第一集中单元CU,且保留所述 终端设备对应的UE上下文;其中,保留的UE上下文用于所述第一DU对所述终端设备下一次发送的上行数据进行数据处理。
具体的,第一CU在接收到第一处理数据后,可以对第一处理数据进行数据处理,包括PDCP和SDAP处理,从而得到第二处理数据,并将第二处理数据发送至核心网设备,从而完成终端设备的上行数据传输。
本实施例中,第一DU保留所述终端设备对应的UE上下文,具体包括以下两种情况:
情况一:
预先通过程序设定等方式设定在完成上行数据处理后,第一DU默认不释放UE上下文;在接收到第一CU发送的释放UE上下文指示消息时,再释放终端设备对应的UE上下文。
情况二:
设定在完成上行数据处理后,第一DU默认释放UE上下文,由第一CU向第一DU发送不释放UE上下文的指示消息后,第一DU根据该指示消息不释放UE上下文。
为了便于理解,本申请各实施例以情况二为例,对本申请的技术方案进行解释说明,可以理解,本申请的技术方案并不仅仅局限于情况二,可以通过对本申请各实施例的方案进行相应的变化以适用于上述情况一。
参考图3,在第一DU保留所述终端设备对应的UE上下文具体为情况二时,还包括:
S4、第一CU向第一DU发送第二消息,第二消息用于指示第一DU保留所述终端设备对应的UE上下文。
相应的,第一DU接收第一CU发送的第二消息,根据第二消息保留所述终端设备对应的UE上下文,从而,终端设备对应的UE上下文在第一DU中保留。在进行下一次的上行数据处理时,第一DU可以根据保留的UE上下文直接对上行数据进行数据处理,得到第一处理数据。
本实施例中,第一DU在接收到处于RRC非活跃态的终端设备发送的上行数据时,对上行数据进行处理并发送至第一CU。此外,第一DU保留所述终端设备对应的UE上下文,在进行下一次的上行数据处理时,第一DU可以根据未释放的UE上下文对下一次的上行数据进行处理,而 无需重新与第一CU建立相应的UE上下文,从而可以简化上行数据的传输流程,提高数据传输效率。
需要说明的是,本申请实施例提供的上行数据处理方法,可以应用于终端设备与其当前所对应的服务网络设备进行小数据传输的应用场景,该应用场景具体可以分为终端设备当前对应的服务CU是否保存有终端设备对应的UE上下文、终端设备当前对应的服务DU是否保存有终端设备对应的UE上下文等多种情况。以下对不同情况下的上行数据处理方法进行具体的解释说明。
在一些实施例中,在终端设备当前对应的服务DU保存有终端设备对应的UE上下文时,对上行数据处理方法的流程进行解释说明。本实施例具体对应在前一次上行数据处理过程中,第一DU未执行释放终端设备对应的UE上下文的操作的情况。
图4为本申请实施例提供的上行数据处理方法的示意图,如图4所示,上行数据处理方法具体包括以下步骤:

其中,第一CU为终端设备当前对应的服务网络设备中的CU,即第一CU为服务CU,第一DU为终端设备当前对应的服务网络设备中的DU,即第一DU为服务DU。
另外,UE上下文具体包括终端设备进入RRC非活跃态之前的SRB(Signalling Radio Bearer,信令无线承载)及DRB((Data Radio Bearer,数据无线承载)的配置,其中DRB配置包括DRB的Qos(Quality Of Service,服务质量)信息以及UL用户面的TNL(传输网络层)地址,以及DRB和Qos Flow的映射关系等。
S100b、终端设备根据第一控制消息进入RRC非活跃态。

S103、第一DU对上行数据进行数据处理,得到第一处理数据。

S104、第一DU向第一CU发送第一处理数据。
S105、第一CU接收第一DU发送的第一处理数据,并进行数据发送处理。

可以理解,在存在后续上行数据时,终端设备将后续上行数据发送至第一DU,第一DU根据保留的UE上下文对后续上行数据进行处理,并将处理后的上行数据发送至第一CU,第一CU对处理后的上行数据进行数据处理后,将处理结果发送至核心网设备。
S106、第一CU根据辅助信息确定终端设备的RRC状态。
具体的,若第一CU根据辅助信息确定当前不存在后续上行数据,且终端设备没有期望的下行数据,第一CU确定终端设备的RRC状态为RRC非活跃态,此时,第一CU发送相应的消息以指示终端设备维持RRC非活跃态。
S107、第一CU向第一DU发送第二消息,第二消息用于指示第一DU保留所述终端设备对应的UE上下文。
S108、第一DU在接收到第一CU发送的第二消息后,保留所述终端设备对应的UE上下文,从而,在进行下一次上行数据传输时,第一DU可以根据保留的UE上下文进行数据处理,而无需与第一CU建立UE上下文。
本实施例提供一种上行数据处理方法,第一DU在接收到处于RRC非活跃态的终端设备发送的上行数据时,根据保留的UE上下文对上行数据进行处理并向第一CU发送处理后的数据,该处理过程中,第一DU无需与第一CU建立UE上下文。然后,第一CU向第一DU发送指示保留终端对应的UE上下文的第二消息,从而,第一DU在完成上行数据的处理后,继续保留终端设备对应的UE上下文,在进行下一次的上行数据处理时,由于第一DU保存有终端设备对应的UE上下文,第一DU无需与第一CU建立相应的UE上下文即可对终端设备发送的上行数据进行处理,从而可以简化上行数据的传输流程,提高数据传输效率。
在一些实施例中,在终端设备当前对应的服务DU未保存有终端设备对应的UE上下文、服务CU保存有终端设备对应的UE上下文时,对上行数据处理方法的流程进行解释说明。本实施例具体对应第一DU未保留有终端设备对应的UE上下文、第一CU保留有终端设备对应的UE上下文的情况。
