附图说明
为了更清楚地说明本公开实施例的技术方案,下面将对本公开实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本公开的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。
图1为相关技术中的节点设备gNB的逻辑功能架构示意图;
图2为本公开的节点设备gNB的逻辑功能架构示意图;
图3为代理实体的建立、重配置、删除以及代理实体之间的交互的流程示意图;
图4为代理实体之间切换的流程示意图。
具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
本公开的实施例,基于灵活的CU架构基于Master-Agent(主架构-代理架构)的逻辑关系,实现以主控实体(Master Entity)为中心,根据DU的需 要,灵活快速的部署代理实体(Agent Entity),从而实现针对第五代(5 Generation,简称5G)移动通信系统的各种业务需求的gNB部署方式。
如图2所示,本公开的实施例提供一种节点设备,包括:
集中单元CU和与所述集中单元CU连接的至少一个分布单元DU;
其中,所述集中单元CU包括:主控实体以及与所述主控实体连接的至少两个代理实体,一个所述分布单元DU与至少一个代理实体连接;
所述主控实体,用于生成管理代理实体的指令;
所述代理实体,用于根据所述指令,代理所述集中单元CU对所述分布单元DU进行管理。
本公开的该实施例中,代理实体(Agent Entity):为CU逻辑节点上执行CU实体功能的功能实例(Instance),是CU功能实体在服务于或者管理每个DU逻辑节点上的具体体现。
每个代理实体的生成、修改和收回(或者删除)都有主控实体进行控制操作和完成。
代理实体由处理流程(Procedures)、支撑这些流程的资源信息数据库和针对这些流程的操作组成。比如,按照目前3GPP规定CU逻辑节点上具有RRC/SDAP/PDCP等协议栈功能。
则代理实体可以为如下CU功能实例:RRC connection(无线链路控制连接)控制相关的所有流程、存储RRC connection的资源信息数据库和相应流程的控制操作。
主控实体在一个DU上生成一个RRC connection实例,包括了RRC connection setup(无线链路控制连接建立)、reconfiguration(重配置)、delete(删除)和failure(释放)等流程,存储四个流程所需的资源信息数据库(包括RRC Connection ID(无线链路控制连接标识),配置的SDAP/PDCP(分组数据汇聚协议)参数,四个流程之间互相转换的操作记录或者状态机),以及这四个流程之间互相转换的规定的操作和判决规则。
本公开的该实施例中,主控实体和代理实体的关系:主控实体控制所有的代理实体的生成、修改和收回(或者删除),并且主控实体负责协调和调度不同代理实体之间的交互。一个DU功能实体上可以对应多个代理实体,主 控实体在生成服务于同一个DU功能实体的多个代理实体时,要确保这多个代理实体在功能是正交的,信令和数据流程是非冲突的。每个代理实体完成赋予的功能。当需要与其他代理实体交互时,需要向主控实体发起申请,然后按照主控实体的指令完成相应的交互。
本公开的该实施例中,代理实体和DU的关系:代理实体可以运行在承载DU功能的硬件设备上,也可以运行在一个独立于DU硬件设备的单独设备。一个DU功能实体可以对应多个CU代理实体。DU功能实体和代理实体的接口遵循3GPP标准规定的CU-DU之间的接口标准。DU功能实体不需要主动选择代理实体,而是主控实体根据无线网络建设、运维和无线功能的设置,直接给每个DU功能实体建立代理实体。在建立每个代理实体时,主控实体配置了DU功能实体与每个代理实体的逻辑连接关系。
本公开的该实施例中,代理实体与代理实体的关系:代理实体之间的关系包括服务同一台DU功能硬件设备的代理实体之间的关系,也包括服务于不同DU功能硬件设备的代理实体之间的关系(用户在不同的DU功能硬件设备间切换时)。代理实体之间的任何交互都要经由主控实体进行控制,裁决和指示后再进行。
本公开的上述实施例中,所述主控实体包括:
协议栈管理模块,用于管理至少一种协议栈;比如,用于实现RRC/SDAP/PDCP等协议栈各种功能集合;
协议实体管理模块,用于根据所述协议栈,生成多个协议实体;比如,管理协议栈,包括生成多个RRC/SDAP/PDCP协议实体,每个用户的RRC/SDAP/PDCP协议实体管理;
模板管理模块,用于管理多种协议实体的功能模板;比如,各种RRC/SDAP/PDCP的功能组合模版,以PDCP为例子,比如PDCP支撑AM模式(确认模式)的功能模版,支撑UM模式(非确认模式)的功能模版;
实体控制模块,用于根据所述功能模板,生成管理代理实体的指令。比如,按照指定需求生成、控制、调度代理实体(Agent Entity)的功能。
本公开的上述实施例中,所述实体控制模块包括:
第一接收单元,用于接收运维单元发送的建立代理实体的指示信息,从 所述多种协议的功能模板中选择至少一功能模板;
第一处理单元,用于根据选择的所述功能模块,生成建立代理实体的建立指令,并建立所述代理实体与分布单元DU之间的连接关系;
代理实体生成单元,用于根据所述建立指令,建立代理实体。
如图3所示,代理实体建立流程:
1、无线网络部署时,选择合适的CU/DU功能模版,并把功能模版发送给主控实体。
2、主控实体收到运维端发送来的指示后,构建代理实体的实例,激活该代理实体的控制管理功能。然后发送代理实体建立请求信令给远端的设备。
3-1、远端设备收到该请求信令后,建立该代理实体。并在建立完毕后,给主控实体回复建立成功响应。代理实体建立成功。
3-2、如果远端设备根据请求信令,无法完成相应的功能,可以回复建立失败相应给主控实体。这里的远端设备可以是承载代理实体的独立的设备,也可以是承载与该代理实体连接的分布单元DU(DU)的设备。
本公开的上述实施例中,所述实体控制模块包括:
第二接收单元,用于接收运维单元发送的删除代理实体的指示信息;
第二处理单元,用于根据所述删除代理实体的指示信息,生成删除对应的代理实体的删除指令,并删除所述代理实体与对应的分布单元DU之间的连接关系;
代理实体删除单元,用于根据所述删除指令,删除所述代理实体。
代理实体删除流程包括:
1、运维端发送来了删除指示。
2、主控实体收到运维端发送来的指示后,发送删除指示给对应的代理实体。
3、远端设备收到删除信令后,删除该代理实体,并回复响应。
本公开的上述实施例中,所述实体控制模块包括:
第三接收单元,用于接收运维单元发送的代理实体重配置的指示信息,并根据所述代理实体重配置的指示信息,从所述多种协议的功能模板中选择一功能模板,并依据选择的功能模板修改原功能模板;
第三处理单元,用于根据修改后的功能模板,对原代理实体进行重配置,生成重配置指令,并对原代理实体与分布单元DU之间的连接关系进行重配置;
代理实体重配置单元,用于根据所述重配置指令,对所述代理实体进行生配置。
代理实体重配制流程包括:
1、运维端需要修改CU/DU功能模版或者某一项功能,把指示发送给主控实体。
2、主控实体收到运维端发送来的指示后,发送代理实体重配制请求信令给远端的设备。
3-1、远端设备收到该请求信令后,重配制该代理实体。并在重配制完毕后,给主控实体回复重配制成功响应。代理实体重配制成功。
3-2、如果远端设备根据请求信令,无法完成相应的功能,可以回复重配制失败相应给主控实体。
本公开的上述实施例中,所述主控实体还用于接收所述至少两个代理实体中的第一代理实体发送的交互请求,并根据所述交互请求从所述至少两个代理实体中除第一代理实体外的其它代理实体中,选择第二代理实体,并建立所述第一代理实体和所述第二代理实体之间的连接关系,并在接收到所述第二代理实体的响应后,配置所述第一代理实体和所述第二代理实体进行交互。
再如图3所示,代理实体间交互流程:
1、源代理实体(第一代理实体)向主控实体发起跨代理实体的交互请求。
2、主控实体收到请求后,选择合适的目的代理实体(第二代理实体),A)如果该目的代理实体还没有建立,则在建立该目的代理实体,并同时建立和源代理实体的连接关系。B)如果该目的代理实体已经建立,则在目的代理实体上建立和源代理实体的连接关系。
3、目的代理实体运行的设备收到主代理的配置信令后,执行信令的配置,建立代理实体(如果信令中配置了),并建立和源代理实体的连接关系。建立成功后,给主控实体回复响应。
4、主代理实体收到目的代理实体的响应后,配置源代理实体可以与目的代理实体进交互。
5、源代理实体与目的代理实体进行交互。
上述过程完成后,主控实体给网络运维实体回复成功响应。
本公开的上述实施例中,所述主控实体还用于接收所述至少两个代理实体中的第一代理实体发送的切换请求或者上报测量;根据所述切换请求或者上报测量,从所述至少两个代理实体中除第一代理实体外的其它代理实体中,选择第二代理实体,并向所述第二代理实体发送切换建立请求,在接收到所述第二代理实体的响应后,配置所述第一代理实体切换到所述第二代理实体。
其中,所述分布单元DU连接的至少一个代理实体为两个以上时,该两个以上的与同一个分布单元DU连接的代理实体的功能是正交的。
如图4所示,代理实体间切换流程:
1、源代理实体(第一代理实体)向主控实体发切换请求或者上报测量。源代理实体发送的切换请求只能来自于更低层(lower layer)的切换判决指示,代理实体本身不具有判决功能。
2、主控实体收到请求后,判决切换触发条件,如果符合切换条件,则选择目的代理实体(第二代理实体),并向代理实体发送建立基本用户信息的切换建立请求,并携带源代理实体的路由信息。
3、目的代理实体运行的设备收到主代理的配置信令后,执行信令的配置,建立代理实体(如果信令中配置了),并建立和源代理实体的连接关系。建立成功后,给主控实体回复响应。
4、主代理实体收到目的代理实体的响应后,配置源代理实体可以切换到目的代理实体。
5、源代理实体与目的代理实体进行用户上下文和数据的前传。
6、切换完成后,源代理实体向主控实体发送切换响应(HO Response)。
7、目的代理实体向主控实体发送切换结束响应(HO Endmark)。
