下面将结合附图,对本申请中的技术方案进行描述。
示例性的,本申请实施例所涉及附图中的以虚线标识的特征或内容可理解为实施例可 选的操作或者可选的结构。
在本申请实施例中,“多个”是指两个或两个以上,其它量词与之类似。
本申请实施例的技术方案可以应用于各种通信***,例如:长期演进(long term evolution,LTE)***、LTE的集中式单元(Centralized Unit,CU)-分布式单元(Distributed Unit,DU)场景、LTE频分双工(frequency division duplex,FDD)***、LTE时分双工(time division duplex,TDD)、通用移动通信***(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信***、第五代(5th generation,5G)***或新无线(new radio,NR)、5G的CU-DU场景等。
图1是本申请的实施例应用的移动通信***的架构示意图。如图1所示,该移动通信***包括核心网设备110、接入网设备120和至少一个终端设备(如图1中的终端设备130和终端设备140)。终端设备通过无线的方式与接入网设备相连,接入网设备通过无线或有线方式与核心网设备连接。核心网设备与接入网设备可以是独立的不同的物理设备,也可以是将核心网设备的功能与接入网设备的逻辑功能集成在同一个物理设备上,还可以是一个物理设备上集成了部分核心网设备的功能和部分的接入网设备的功能。终端设备可以是固定位置的,也可以是可移动的。图1只是示意图,该通信***中还可以包括其它网络设备,如还可以包括无线中继设备和无线回传设备,在图1中未画出。本申请的实施例对该移动通信***中包括的核心网设备、无线接入网设备和终端设备的数量不做限定。
接入网可以为采用不同接入技术的接入网络。目前的无线接入技术有两种类型:第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)接入技术(例如3G、4G或5G***中采用的无线接入技术)和非第三代合作伙伴计划(non-3GPP)接入技术。3GPP接入技术是指符合3GPP标准规范的接入技术,采用3GPP接入技术的接入网络称为无线接入网络(Radio Access Network,RAN),其中,5G***中的接入网设备称为下一代基站节点(next generation Node Base station,gNB)。非3GPP接入技术是指不符合3GPP标准规范的接入技术,例如,以wifi中的接入点(access point,AP)为代表的空口技术。基于无线通信技术实现接入网络功能的接入网可以称为无线接入网(radio access network,RAN)。第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)的5G无线接入网可以称为下一代无线接入网(next generation radio access network,NG-RAN)。
接入网设备是终端设备通过无线方式接入到该移动通信***中的接入设备。接入网设备可以是无线接入网RAN设备、基站NodeB、演进型基站(evloved NodeB,eNB)、5G移动通信***中的下一代基站gNB、传输点、未来移动通信***中的基站或无线保真(wireless fidelity,Wi-Fi)***中的接入节点,5G***中的基站的一个或一组(包括多个天线面板)天线面板,或者,还可以为构成gNB或传输点的网络节点,如基带单元(baseband unit,BBU),或,分布式单元DU等。本申请的实施例对接入网设备所采用的具体技术和具体设备形态不做限定。在一些部署中,gNB可以包括CU和DU。gNB还可以包括有源天线单元(active antenna unit,AAU)。CU实现gNB的部分功能,DU实现gNB的部分功能。比如,CU负责处理非实时协议和服务,以实现无线资源控制(radio resource control,RRC),分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能。DU负责处理物理层协议和实时服务,以实现无线链路控制(radio link control, RLC)层、媒体接入控制(media access control,MAC)层和物理(physical,PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息,或者,由PHY层的信息转变而来,因而,在这种架构下,高层信令,如RRC层信令,也可以认为是由DU发送的,或者,由DU+AAU发送的。可以理解的是,网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外,可以将CU划分为接入网中的网络设备,也可以将CU划分为核心网(core network,CN)中的网络设备,本申请对此不做限定。
终端设备也可以称为终端Terminal、用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等。终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
接入网设备和终端设备可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上;还可以部署在空中的飞机、气球和卫星上。本申请的实施例对无线接入网设备和终端设备的应用场景不做限定。
本申请的实施例可以适用于下行信号传输,也可以适用于上行信号传输,还可以适用于设备到设备(device to device,D2D)的信号传输。对于下行信号传输,发送设备是无线接入网设备,对应的接收设备是终端设备。对于上行信号传输,发送设备是终端设备,对应的接收设备是无线接入网设备。对于D2D的信号传输,发送设备是终端设备,对应的接收设备也是终端设备。本申请的实施例对信号的传输方向不做限定。
接入网设备和终端设备之间以及终端设备和终端设备之间可以通过授权频谱(licensed spectrum)进行通信,也可以通过免授权频谱(unlicensed spectrum)进行通信,也可以同时通过授权频谱和免授权频谱进行通信。接入网设备和终端设备之间以及终端设备和终端设备之间可以通过6千兆赫(gigahertz,GHz)以下的频谱进行通信,也可以通过6G以上的频谱进行通信,还可以同时使用6G以下的频谱和6G以上的频谱进行通信。本申请的实施例对接入网设备和终端设备之间所使用的频谱资源不做限定。
在本申请实施例中,终端设备或网络设备包括硬件层、运行在硬件层之上的操作***层,以及运行在操作***层上的应用层。该硬件层包括中央处理器(central processing unit,CPU)、内存管理单元(memory management unit,MMU)和内存(也称为主存)等硬件。该操作***可以是任意一种或多种通过进程(process)实现业务处理的计算机操作***,例如,Linux操作***、Unix操作***、Android操作***、iOS操作***或windows操作***等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且,本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定,只要能够通过运行记录有本申请实施例的提供的方法的代码的程序,以根据本申请实施例提供的方法进行通信即可,例如,本申请实施例提供的方法的执行主体可以是终端设备或网络设备,或者,是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外,本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技 术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如,计算机可读介质可以包括,但不限于:磁存储器件(例如,硬盘、软盘或磁带等),光盘(例如,压缩盘(compact disc,CD)、数字通用盘(digital versatile disc,DVD)等),智能卡和闪存器件(例如,可擦写可编程只读存储器(erasable programmable read-only memory,EPROM)、卡、棒或钥匙驱动器等)。另外,本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于,无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图2是应用本申请实施例的另一通信架构图。如图2所示,核心网设备103,比如,第五代核心网(the 5th generation core network,5GC)为例,既可以连接完整的接入网设备101,如gNB,也可以连接包括集中式单元(Centralized Unit,CU)201和分布式单元(Distributed Unit,DU)202的接入网设备102。可以理解,CU201和DU202可以为物理实体,也可以为软件化或虚拟化单元(或模块)。还可以理解,CU201和DU202可以部署在同一设备,也可以部署在不同设备上,对此不作限定。
CU201和DU202可软件化或虚拟化,需要灵活组合的无线接入网络功能将运行在CU201中,例如,业务数据适应协议(Service Data Adaptation Protocol,SDAP)层、分组数据汇聚协议(Packet Data Convergence Protocol,PDCP),无线资源控制(Radio Resource Control,RRC)等高层功能;而与硬件强相关并且实时性要求较高的RAN功能将运行在DU202中,例如无线链路层控制协议(Radio Link Control,RLC)层、物理层(physical layer,PHY),媒体介入控制层(Media Access Control,MAC)等底层功能。
CU201和DU202之间通过通信接口相连。CU201与核心网设备之间也通过通信接口相连。在本申请实施例中,CU201和DU202之间的通信接口可以称为F1接口。CU201与核心网设备之间的接口可称为N2接口或NG接口。如图2所示,一个接入网设备102可以包括一个CU201、一个或多个DU202。CU201与DU202之间采用F1接口相连。一个DU202只能连接到一个CU201,一个CU201可以与一个或多个DU202相连。
例如,以接入网设备102为gNB为例,该gNB可以包括一个或多个gNB-DU,以及一个gNB-CU。一个gNB-DU连接到一个gNB-CU,一个gNB-CU可以连接到多个gNB-DU。gNB-CU和它连接的gNB-DUs在其它gNB和5GC看来就是一个gNB。
图3是在图2架构的基础上,提出了一种新的架构,即CU包括集中式单元-用户面(Centralized Unit-user plane,CU-UP)301和集中式单元-控制面(Centralized Unit-control plane,CU-CP)302。其中CU-UP301和CU-CP302可以是在不同的物理设备上。CU-UP301和CU-CP302之间可以存在一个开放的接口,该接口可以称为E1接口。与此同时,CU-UP301和CU-CP302与DU均可以有各自的接口,例如,可以称CU-CP302与DU之间的接口为F1-C接口,CU-UP301与DU之间的接口为F1-U接口。
针对图3的架构,可以具有以下特性:一个接入网设备102可以包括一个CU-CP302、一个或多个CU-UP302、多个DU。一个DU可以连接一个CU-CP302。一个CU-UP301只可以连接一个CU-CP302。一个DU在同一个CU-CP302的控制下可以连接到多个CU-UP301。一个CU-UP301在同一个CU-CP302的控制下可以连接到多个DU。
例如,以接入网设备102为gNB为例,一个gNB-DU和gNB-CU-UP都只连接到一个gNB-CU-CP。在同一个gNB-CU-CP控制下,一个gNB-DU可以连接到多个gNB-CU-UP, 一个gNB-CU-UP可以连接到多个gNB-DU。
可以理解,图1至图3中的通信***只是示例性地描述,并不对本申请实施例的保护范围构成限定。本申请实施例的技术方案也可以用于其他通信***。
目前的网络规划或网络优化过程中,并未考虑CU-DU分离的场景下,如何传输小区的覆盖状态。本申请提供一种通信方法,能够在CU-DU分离架构下实现小区覆盖状态指示的传输,有助于提高网络性能。
图4示出了根据本申请实施例的通信方法400的示意***互图。可以理解,图4中的CU与DU之间交互的部分或全部信息,可以携带于已有的消息、信道、信号或信令中,也可以是新定义的消息、信道、信号或信令,对此不作具体限定。比如,CU与DU之间交互的部分或全部信息可以携带于现有的F1接口的消息,或者,也可以携带于新定义的F1接口的消息。还可以理解,下文中的第一网络设备可以是前文提到的接入网设备,比如,图1中的接入网设备120,或者,图2中的接入网设备101或接入网设备102,或者,图3中的接入网设备。如图4所示,所述方法400包括:
S401,第一网络设备的分布式单元DU确定第一覆盖指示,所述第一覆盖指示包括以下中的一项或多项:第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,所述第一小区的小区替换信息。
也就是说,第一网络设备的DU可以确定第一小区的以下三类信息(或者,三类信息可以称为三个子信元(information element,IE))中的部分或全部:第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,所述第一小区的小区替换信息。下面对每个子信元进行解释。
小区覆盖状态(cell coverage state)用于指示DU下小区是否处于激活状态。比如,“0”表示小区处于非激活状态;其他值表示小区处于激活状态,也表示小区的覆盖配置。其中,小区的覆盖配置属于具体实现,标准可以不定义。
小区规划状态指示(cell deployment status indicator)用于指示DU下小区的部署状态,比如,小区覆盖状态规划在下次重配时使用的指示。
小区替换信息(cell replacing info)用于指示替换第一小区的小区标识,可以替换所有或部分被小区的覆盖范围。比如,小区替换信息包括小区的全局标识。需要说明的是,本申请实施例对替换小区的数量不作限定。也就是说,所述第一小区的小区替换信息,可以包括一个或多个替换小区的相关信息,对此不作限定。
S402,第一网络设备的DU向第一网络设备的集中式单元CU发送第一覆盖指示以及第一标识,其中,所述第一标识用于标识所述第一小区。对应的,第一网络设备的CU接收来自第一网络设备的DU的第一覆盖指示以及第一标识。
其中,第一标识与所述第一覆盖指示是对应的。第一标识为所述第一小区的标识信息。比如,第一标识为物理小区标识(physical cell ID,PCI),小区全球标识(cell global identifier,CGI)等。
这里作统一说明,在本申请实施例中,小区(不论是第一小区、第二小区,还是替换小区)的标识信息可以包括小区全球标识。在LTE中,小区全球标识可用ECGI表示,其中,E为演进的UMTS陆地无线接入网(evolved UMTS terrestrial radio access network,E-UTRAN)的简称。在NR中,小区全球标识可以用CGI表示,或者,也可以用NRCGI 表示。为了避免冗余,下文出现的小区全球标识将不再赘述其含义。
在本申请实施例中,第一网络设备的DU通过将第一覆盖指示中的部分或全部子信元以及第一标识发送给第一网络设备的CU,以便于实现在CU-DU分离架构下实现小区覆盖状态指示的传输,有助于提高网络性能。
可选地,所述方法400还包括:S403,第一网络设备的CU向第一网络设备的DU发送第二覆盖指示和/或第二标识,所述第二覆盖指示包括以下中的一项或多项:第二小区的小区覆盖状态,所述第二小区的小区规划状态指示,所述第二小区的小区替换信息,其中,所述第二标识用于标识所述第二小区。对应的,第一网络设备的DU接收来自第一网络设备的CU的第二覆盖指示和/或第二标识。其中,其中,第二覆盖指示是邻区对应的覆盖配置,第二标识用于标识该邻区。
也就是说,第一网络设备的CU在得到邻区的覆盖配置时,可以将邻区的覆盖配置,比如,第二覆盖指示和/或第二标识,发送给第一网络设备的DU。这里,第二覆盖指示中包括的各个子信元的具体描述可以参考第一覆盖指示,为了简洁,这里不作赘述。
可选地,所述第二覆盖指示和/或第二标识可以是第一网络设备从第二网络设备获取的。第二网络设备为邻基站。具体例如,第一网络设备的CU可以接收邻站发送的所述第二覆盖指示和/或第二标识,能够获取到邻区的覆盖状态,从而基于邻区的覆盖状态调整天线相关参数等。
可选地,第一网络设备的CU可以通过现有接口消息或者新定义的消息向第一网络设备的DU发送第二覆盖指示和/或第二标识。例如,现有消息可以是现有F1接口消息,包括GNB-DU CONFIGURATION UPDATE ACKNOWLEDGE消息和GNB-CU CONFIGURATION UPDATE消息。下面结合表1描述第二覆盖指示以及第二标识。
表1
在上述表1中,以NR为例,第二覆盖指示以及第二标识通过表1中的邻小区覆盖修改列表中包括的内容进行描述,例如,从表1第三行可以看到,第二标识为CGI,表示待修改小区的CGI;从表1第四行至第六行可以看到,第二覆盖指示包括的3个子信元分别为:Cell Coverage State、Cell Deployment Status Indicator以及Cell Replacing Info。其中,从表1第七行和第八行可以看到,Cell Replacing Info包括替换小区的信息,比如,替换小 区的信息包括替换小区的标识信息,比如,替换小区的标识信息可以是CGI。
可以理解,表1是以NR为例进行描述,但不对本申请实施例构成限定。事实上,若是LTE***进行描述,CGI可以替换为ECGI。
可以理解,上述表1只是示例性地举例,并不对本申请实施例构成限定,事实上,表1中各个信元的名称也可以有其他定义,对此不作具体限定。
在本申请实施例中,第一网络设备的DU可以确定第一覆盖指示中的部分或全部子信元。下面将分别描述可能的实现方式。
作为一种可能的实现方式,第一网络设备的DU确定的第一覆盖指示中,包括第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,以及,所述第一小区的小区替换信息。也就是说,第一网络设备的DU可以确定包括第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,以及,所述第一小区的小区替换信息的第一覆盖指示,并将第一覆盖指示以及第一标识发送给第一网络设备的CU。为了便于描述,这里将第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,以及,所述第一小区的小区替换信息称为3个子信元。
可选地,第一网络设备的DU可以通过现有接口消息或者新定义的消息向第一网络设备的CU发送所述第一覆盖指示以及第一标识,其中,所述第一覆盖指示包括上述3个子信元。例如,现有消息可以是现有F1接口消息,包括GNB-DU CONFIGURATION UPDATE消息或者GNB-CU CONFIGURATION UPDATE ACKNOWLEDGE消息。下面结合表2描述第一覆盖指示以及第一标识。
表2
在上述表2中,以NR为例,第一覆盖指示以及第一标识通过覆盖修改列表中包括的内容进行描述,例如,从表2的第三行可以看到,第一标识为CGI,表示待修改小区(比如,第一小区为待修改小区)的CGI;从表2的第四行至第六行可以看到,第一覆盖指示包括的3个子信元分别为:Cell Coverage State、Cell Deployment Status Indicator以及Cell Replacing Info。其中,从表2的第七行和第八行可以看到,Cell Replacing Info包括替换小区的标识信息,比如,替换小区的标识信息可以是CGI。
可以理解,表2是以NR为例进行描述,但不对本申请实施例构成限定。事实上,若是LTE***进行描述,CGI可以替换为ECGI。
还可以理解,上述表2只是示例性地举例,并不对本申请实施例构成限定,事实上,表1中各个信元的名称也可以有其他定义,对此不作具体限定。
作为另一种可能的实现方式,第一网络设备的DU确定的第一覆盖指示中,包括第一小区的小区覆盖状态,以及,所述第一小区的小区规划状态指示。所述第一小区的小区替换信息是第一网络设备的CU确定的。
可选地,所述方法400还包括:第一网络设备的CU向第一网络设备的DU发送第三覆盖指示以及所述第一标识,所述第三覆盖指示包括所述第一小区的小区替换信息。可选地,第一小区的小区替换信息中可以包括第三标识,所述第三标识用于标识第三小区。所述第三小区是所述第一小区的替换小区。
也就是说,第一网络设备的DU确定上述3个子信元中的第一小区的小区覆盖状态,以及,所述第一小区的小区规划状态指示;第一网络设备的CU确定上述3个子信元中的所述第一小区的小区替换信息。这里,第一网络设备的CU向第一网络设备的DU发送第三覆盖指示时,还需要发送第一标识,目的在于让DU得知第三覆盖指示中包括的内容也是与第一小区相关的,即,第三覆盖指示中包括的是第一标识所标识的第一小区的小区替换信息。
所述第三小区是所述第一小区的替换小区可以通过以下例子理解。例如,第一小区是小区A,第三小区是小区B,则将小区A替换为小区B。
可以理解,上面只是以第三小区是第一小区的替换小区为例进行描述,并不对本申请实施例的保护范围构成限定。事实上,第一小区的替换小区可以包括一个或多个小区。
示例性的,第一网络设备的CU收到第一网络设备的DU发送的第一覆盖指示,然后确定所述第三覆盖指示识,并将所述第三覆盖指示以及第一标识发送给第一网络设备的DU。
可选地,第一网络设备的DU可以通过现有接口消息或者新定义的消息向第一网络设备的CU发送所述第一覆盖指示以及第一标识,其中,所述第一覆盖指示包括第一小区的小区覆盖状态,以及,所述第一小区的小区规划状态指示。例如,现有消息可以是现有F1接口消息,包括GNB-DU CONFIGURATION UPDATE消息或者GNB-CU CONFIGURATION UPDATE ACKNOWLEDGE消息。下面结合表3描述第一覆盖指示以及第一标识。
表3
在上述表3中,以NR为例,第一覆盖指示以及第一标识通过覆盖修改列表中包括的内容进行描述,例如,从表3的第三行可以看到,第一标识为CGI,表示待修改小区(比如,第一小区为待修改小区)的CGI;从表3的第四行和第五行可以看到,第一覆盖指示包括的2个子信元分别为:Cell Coverage State以及Cell Deployment Status Indicator。可见,表2与表3的区别在于,表3中不包括Cell Replacing Info。
可以理解,表3是以NR为例进行描述,但不对本申请实施例构成限定。事实上,若是LTE***进行描述,CGI可以替换为ECGI。可以理解,上述表3只是示例性地举例,并不对本申请实施例构成限定,事实上,表2中各个信元的名称也可以有其他定义,对此不作具体限定。
可选地,第一网络设备的CU向第一网络设备的DU发送第三覆盖指示以及第一标识,包括:第一网络设备的CU通过现有接口消息或者新定义的消息向第一网络设备的DU发送所述第三覆盖指示以及第一标识。例如,现有消息可以是现有F1接口消息,包括GNB-DU CONFIGURATION UPDATE消息或者GNB-CU CONFIGURATION UPDATE ACKNOWLEDGE消息。下面结合表4描述第三覆盖指示以及第一标识。

从上述表4可知,第一网络设备的CU在向第一网络设备的DU发送Cell Replacing Info时,还可以携带CGI,即待修改小区的小区全球标识。
可以理解,表4是以NR为例进行描述,但不对本申请实施例构成限定。事实上,若是LTE***进行描述,CGI可以替换为ECGI。还可以理解,上述表4只是示例性地举例,并不对本申请实施例构成限定,事实上,表3中各个信元的名称也可以有其他定义,对此不作具体限定。
应理解,上文只是以第一网络设备的DU确定第一小区的小区覆盖状态和所述第一小区的小区规划状态指示,以及,第一网络设备的CU确定所述第一小区的小区替换信息为例进行说明,但并不对本申请实施例构成限定。事实上,第一网络设备的DU可以确定以下中的任意一项或两项:第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,所述第一小区的替换信息,然后由第一网络设备的CU来确定其他项,对此不作限定。
可以理解,在本申请实施例中,第一网络设备的CU在得到第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,以及,所述第一小区的替换信息后,也可以向邻站进行发送。比如,对于邻站而言,若邻站也是CU-DU架构,第一网络设备的CU向第二网络设备的CU发送第四覆盖指示,所述第四覆盖指示包括以下中的一项或多项:第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,所述第一小区的替换信息,以及第一标识。当然,第二网络设备的CU也可以将第四覆盖指示发送给第二网络设备的CU管理的DU。可选地,第二网络设备的CU还可以向第二网络设备的DU发送第一标识,所述第一标识对应于第四覆盖指示。
举例来说,以第一网络设备的CU是CU1,第二网络设备的CU是CU2,CU2下包括DU1和DU2为例,CU2可以向DU1和DU2发送所述第四覆盖指示。
在本申请实施例中,第一网络设备的DU可以确定第一覆盖指示中的一项或多项,并将第一覆盖指示提供给第一网络设备的CU,从而在CU-DU分离架构下实现小区覆盖状态指示的传输,有助于提高网络性能。
本申请还提供一种通信方法。在该通信方法中,第一网络设备的CU可以确定第一覆盖指示,并将第一覆盖指示以及第一标识发送给第一网络设备的DU。
图5示出了根据本申请另一实施例的通信方法500的示意***互图。可以理解,图5中的CU与DU之间交互的部分或全部信息,可以携带于已有的消息、信道、信号或信令中,也可以是新定义的消息、信道、信号或信令,对此不作具体限定。比如,CU与DU之间交互的部分或全部信息可以携带于现有的F1接口的消息,或者,也可以携带于新定义的F1接口的消息。如图5所示,所述方法500包括:
S501,第一网络设备的CU确定第一覆盖指示,所述第一覆盖指示包括以下中的一项或多项:第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,所述第一小区的小区替换信息。

可以理解,第一网络设备的CU也可以通过现有接口消息或者新定义的消息向第一网络设备的DU发送所述第一覆盖指示以及第一标识,其中,所述第一覆盖指示包括上述3个子信元。例如,现有消息可以是现有F1接口消息,包括GNB-DU CONFIGURATION UPDATE ACKNOWLEDGE消息和GNB-CU CONFIGURATION UPDATE消息。
下面结合表5描述第一覆盖指示以及第一标识。
表5

可以理解,表5是以NR为例进行描述,但不对本申请实施例构成限定。事实上,若是LTE***进行描述,CGI可以替换为ECGI。
还可以理解,上述表5只是示例性地举例,并不对本申请实施例构成限定,事实上,表1中各个信元的名称也可以有其他定义,对此不作具体限定。
可选地,所述方法500还包括:S503,所述第一网络设备的CU向所述第一网络设备的DU发送第二覆盖指示和/或第二标识,所述第二覆盖指示包括以下中的一项或多项:第二小区的小区覆盖状态,所述第二小区的小区规划状态指示,所述第二小区的小区替换信息,所述第二标识用于标识所述第二小区。对应的,第一网络设备的DU接收来自第一网络设备的CU的第二覆盖指示和/或第二标识。其中,第二覆盖指示是邻区对应的覆盖配置,第二标识用于标识该邻区。这里,第一网络设备的CU向第一网络设备的DU发送邻站的第二覆盖指示和/或第二标识可以参考前文方法400中的描述,为了避免冗余,这里不作赘述。
可以理解,在该方法500中,第一网络设备的CU也可以通过现有接口消息或者新定义的消息向第一网络设备的DU发送第二覆盖指示和/或第二标识。例如,现有消息可以是现有F1接口消息,包括GNB-DU CONFIGURATION UPDATE ACKNOWLEDGE消息和GNB-CU CONFIGURATION UPDATE消息。第二覆盖指示以及第二标识可以参考前文表1中的描述,为了避免冗余,这里不作赘述。
下文将描述第一网络设备如何确定所述第一覆盖指示。
可选地,所述方法500还包括:第一网络设备的CU获取多个覆盖配置;其中,S501包括:第一网络设备的CU根据多个覆盖配置,为所述第一小区确定第一覆盖指示。
其中,多个覆盖配置可以替换为多个候选覆盖状态。
可选地,CU获取的多个覆盖配置可以为一个候选覆盖配置列表(或者候选覆盖配置集合),候选覆盖配置列表中包括多个覆盖配置,每个覆盖配置中包括以下中的一项或多项:cell coverage state,cell deployment status indicator,cell replacing info。可选地,若多个覆盖配置是小区粒度的,那么每个覆盖配置中还可以包括与该覆盖配置对应的小区标识信息。比如,若CU获取的候选覆盖配置列表是针对不同小区的,那么CU还需要获取每个覆盖配置对应的小区标识。可选地,CU获取的候选配置覆盖列表可以是针对一个小区的候选覆盖配置列表。该CU下每个小区都有一个候选覆盖配置列表。也就是说,CU为每个小区在该小区对应的候选覆盖配置列表中确定合适的覆盖配置。或者,可选地,CU获取的候选配置覆盖列表也可以是一个CU的候选覆盖配置列表,即该CU获取一个候选覆盖配置列表,CU为每个小区在该候选覆盖配置列表中确定合适的覆盖配置。
第一网络设备的CU在获得多个覆盖配置后,可以为第一小区选择合适的覆盖配置,比如,为第一小区选择的覆盖配置通过第一覆盖指示表示。
一般而言,多个覆盖配置可以是由集中管理***来配置,比如操作、管理和维护(operation,administration and maintenance,OAM)配置的,或者,由其他集中管理节点配置。每个覆盖配置中包括的内容可以参考前文描述。具体如何为小区选择覆盖配置有以下不同的方式。例如,OAM可以为每个小区确定覆盖配置。或者,又例如,OAM可以为每个小区确定一个候选覆盖配置列表。或者,又例如,OAM可以为网络设备确定一个候选覆盖配置列表,由网络设备为其服务的每个小区动态选择最合适的覆盖配置。
若第一网络设备的CU的OAM与第一网络设备的DU的OAM是不同的OAM,则第一网络设备的CU确定第一覆盖指示可能有不同的方式,下面将分别描述。
可选地,所述第一网络设备的CU获取多个覆盖配置,包括:第一网络设备的CU的运维管理操作***OAM为所述第一网络设备的CU配置多个覆盖配置。也就是说,第一网络设备的CU的OAM可以给CU配置多个覆盖配置,然后,第一网络设备的CU从多个覆盖配置中为第一小区选择合适的覆盖配置,比如,所述第一覆盖指示。这里,第一网络设备的CU如何从多个覆盖配置中为第一小区选择合适的覆盖配置属于产品具体实现,这里不作具体限定,比如,第一网络设备的CU可以基于邻区关系的覆盖配置为第一小区选择合适的覆盖配置。
可选地,所述第一网络设备的CU获取多个覆盖配置,包括:所述第一网络设备的DU的运维管理操作***OAM为所述第一网络设备的DU配置多个覆盖配置;所述第一网络设备的DU向所述第一网络设备的CU发送所述多个覆盖配置。也就是说,第一网络设备的DU的OAM给DU配置小区的多个覆盖配置,然后DU将多个覆盖配置发送给CU,由CU决定在多个覆盖配置中选择合适的覆盖配置,比如,所述第一覆盖指示。对于多个覆盖配置与多个小区一一对应的情形,那么DU需要将多个覆盖配置以及与每个覆盖配置对应的小区标识发送给CU,由CU决定为第一小区在该多个覆盖配置中选择合适的覆盖配置。
可选地,所述方法500还包括:所述第一网络设备的DU的运维管理操作***OAM 为所述第一网络设备的DU配置多个覆盖配置;所述第一网络设备的DU在所述多个覆盖配置中,为所述第一小区确定所述第一覆盖指示;所述第一网络设备的DU向所述第一网络设备的CU发送所述第一覆盖指示。也就是说,第一网络设备的DU的OAM给DU配置小区的多个覆盖配置,然后DU在多个覆盖配置中选择合适的覆盖配置,比如,所述第一覆盖指示,最后将为第一小区选择的覆盖配置发送给CU。这里,第一网络设备的DU如何从多个覆盖配置中为第一小区选择合适的覆盖配置属于产品具体实现,这里不作具体限定,比如,第一网络设备的DU可以基于邻区关系的覆盖配置为第一小区选择合适的覆盖配置。
因此,通过上述各个实现方式可以看出,即使第一网络设备的CU的OAM与第一网络设备的DU的OAM是不同的OAM,第一网络设备的CU也能够确定第一覆盖指示。
可选地,在方法500中,第一网络设备的CU也可以将确定的第一小区的小区覆盖状态,所述第一小区的小区规划状态指示,所述第一小区的小区替换信息发送给邻站。具体描述可以参考前文,为了避免冗余,这里不作赘述。
