Description

数据交互的方法、装置及设备 技术领域
本公开涉及互联网技术领域,尤其涉及一种数据交互的方法、装置及设备。
背景技术
无线网络进入5G时代,将基站功能进行了拆分和解耦,例如集中式单元(Centralized Unit,DU)和分布式单元(Distributed Unit,CU)的分离部署,这样促使了基站从集中式基站系统向分布式基站系统转变。在本文中,分布式基站和分布式基站系统可以互换地使用。分布式基站系统对基站配置的数据模型提出了新的要求,所述要求例如以下三点要求。
1、分布式基站系统中有多个子系统,每个子系统允许有多个实例,相同子系统的多个实例可以有不同版本的模型定义。
2、分布式基站系统对外仍然呈现为一个完整的基站网元,因此它的配置建模对外部设备来说仍然是一个完整的配置模型,而不是一些独立的子系统模型(即整个基站网元模型由多个子系统模型组合而成)。
3、为了实现系统的标准化,分布式基站系统必须使用标准的建模语言进行建模,并提供标准的数据访问接口。
目前,在使用诸如:YANG(Yet Another Next Generation)建模语言RFC(Request for Comments,请求评议)6021等标准的建模语言来建立分布式基站系统的数据模型时,虽然可以描述基站的配置模型,但是在使用标准建模语言实现上述3点要求时仍存在以下问题:在标准建模语言中,虽然可以按多个子系统分别建模,并可以将其合并成一个完整的系统模型,但是这要求不同子系统使用的数据模型版本必须相同,无法实现不同子系统使用不同的数据模型版本。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述。
本公开实施例中,分布式基站系统可以包括:网元代理模块,网元代理模块设置为实现分布式基站系统与外部设备的数据交互。
图1为根据本公开实施例的分布式基站系统的组成结构示意图。如图1所示,分布式基站系统10包括:网元代理模块102和多个子系统101,网元代理模块102与每一个子系统相连,外部设备11通过网元代理模块102实现与分布式基站10内部的每一个子系统的数据交互。分布式基站系统10相对于外部设备11相当于一个整体。
所述多个子系统101包括:101a子系统1,对应的数据模型为模型a版本v1;101b子系统2,对应的数据模型为模型a版本v2;101c子系统3,对应的数据模型为模型b版本v1;101d子系统4,对应的数据模型为模型b版本v1。这里,每一个子系统都有各自对应的数据模型,且所述数据模型可以不同。
本公开实施例中提供的数据模型建立方法和数据交互方法可以应用在5G通信系统中。
图2为根据本公开实施例的数据交互的方法的一种流程示意图。如图2所示,该方法包括:步骤21-23。
在步骤21,为分布式基站中的每个子系统建立数据模型。
本公开实施例中,每个子系统的数据模型用于表征子系统的数据处理方式,分布式基站的所有子系统的数据模型中至少存在两个具有指定关系的数据模型,其中,指定关系为数据模型的类型信息相同但数据模型的版本信息不同。
示例性的,通过网络配置(Network Configuration,Netconf),通讯协议实现外部设备与分布式基站系统的数据交互。Netconf通讯协议的数据建模语言可以是:XSD(XML Schema Definition,XML架构定义)语言、NCX(Network Configuration Extensions,网络配置扩展)语言、YANG语言等,可以使用标准的建模语言来建立数据模型。
示例性的,每个子系统的数据模型包括:子系统身份标识ID、子系统的数据模型的类型信息和子系统的数据模型的版本信息。这里,子系统的数据模型的类型信息即为子系统的类型信息。在实际应用中,子系统类型可以包括:低频子系统、高频子系统、集中式子系统、分布式子系统等,可以根据子系统的类型信息来建立对应类型的数据模型。在一些情况下,子系统只能使用相同版本的数据模型,而在本公开中,可以为子系统建立具有相同类型信息但具有不同版本信息的数据模型。
具体的,子系统的数据模型的结构为树形结构,子系统的数据模型至少包括:根节点和与根节点相连的属性子节点,其中,所述根节点包括:分布式基站的标识信息,所述标识信息可以是分布式基站的ID,所述属性子节点包括:子系统ID、子系统数据模型的类型信息和子系统数据模型的版本信息。
图3为根据本公开实施例的子系统的数据模型的结构示意图。如图3所示,利用标准的建模语言建立的子系统的数据模型包括:根节点31、属性子节点32和多个业务子节点33,其中,属性子节点32为根节点31的子节点,多个业务子节点33均为属性子节点32的 子节点,即每一个业务子节点在子系统的数据模型的树形结构中均为叶子节点,子系统的数据模型中只能有一个属性子节点,但可以有n种不同属性子节点,n取正整数。
如图3所示,根节点31中可以包括:根节点名称(即网元节点)和网元节点ID。属性子节点32可以包括:属性子节点名称(即xxx子节点)、子系统ID、类型信息(即xxx)和版本信息(即v1)。属性子节点名称中可以包含类型信息。多个业务子节点33包括:业务子节点1、业务子节点2等,每一个业务子节点包含子系统执行的具体业务信息。本公开实施例中,网元节点是指分布式基站系统。
在步骤22,根据分布式基站的所有子系统的数据模型来建立网元代理模块的数据模型。
本公开实施例中,网元代理模块的数据模型用于表征网元代理模块与分布式基站的每一个子系统的数据交互方式,外部设备依据网元代理模块的数据模型实现与每一个子系统的数据交互。
示例性的,在子系统的数据模型包括子系统身份标识ID、子系统的数据模型的类型信息和子系统的数据模型的版本信息的情况下,本步骤可以包括以下步骤:获取所有子系统的数据模型;以及利用获取的所有子系统的数据模型中的子系统ID和类型信息来建立网元代理模块的数据模型。
具体的,网元代理模块的数据模型的结构为树形结构,网元代理模块的数据模型包括:根节点和与根节点相连的多个属性子节点,每一个属性子节点对应一个子系统,其中,所述根节点包括:分布式基站系统的标识信息,并且所述属性子节点包括:子系统ID和子系统的数据模型的类型信息。
图4为根据本公开实施例的网元代理模块的数据模型的结构示意图。如图4所示,利用标准的建模语言建立的网元代理模块的数据模型包括:根节点41和多个属性子节点42,其中,所述多个属性子节点42包括:子系统1对应的xxx子节点、子系统2对应的yyy子节点、子系统1对应的zzz子节点等。xxx、yyy和zzz分别表示子系统1、子系统2和子系统3的类型信息,也表示每一个子系统的数 据模型的类型信息。
这里,每一个属性子节点为根节点41的子节点,每一个属性子节点也为树形结构中的叶子节点,分布式基站系统中一个子系统对应一个属性子节点。由于一个子系统可以具有多种不同的数据模型,因此,网元代理模块的数据模型中一个子系统可以对应的多种属性子节点,但一个子系统对应的所有属性子节点中的子系统ID都相同,图中子系统1可以有a种不同的属性子节点,子系统2可以有b种不同的属性子节点,子系统3可以有c种不同属性子节点,其中,a、b、c均取正整数。
如图4所示,根节点41包括:根节点名称(即,“网元节点”)和网元节点ID;多个属性子节点42中的每一个属性子节点包括:属性子节点名称(,即“xxx子节点”)、子系统ID;属性子节点名称可以对应子系统的类型。
在步骤23,根据网元代理模块的数据模型,通过网元代理模块来实现与多个子系统的数据交互。
本步骤中还包括:获取数据模型集合。这里,获取数据模型集合的方法可以是:网元代理模块读取每一个子系统对应的数据模型,所有子系统的数据模型组成了数据模型集合,将数据模型集合发送给外部设备。
示例性的,数据交互可以包括:下发数据和上报数据。
本步骤中实现下发数据的步骤可以包括以下步骤:根据数据模型集合生成待下发数据;在待下发数据中包含子系统ID的情况下,将待下发数据发送至网元代理模块中,网元代理模块根据自身的数据模型对待下发数据进行解析,得到至少一个解析后的数据;根据每一个解析后的数据中包含的子系统ID,将每一个解析后的数据下发至对应的子系统中;在待下发数据中不包含子系统ID的情况下,将待下发数据发送至网元代理模块中,使网元代理模块根据自身的数据模型中包含的所有子系统ID,将待下发数据下发至所有子系统中。
本步骤中实现接收上报数据的步骤可以包括以下步骤:接收网元代理模块的透传数据,其中,所述透传数据包括由分布式基站的至 少一个子系统上报的数据。
当透传数据中包含子系统的数据模型的修改信息时,根据接收到的透传数据更新数据模型集合。
本领域技术人员应理解,透传指的是透明传输,并且需要说明的是,在下一次向分布式基站系统下发数据时,根据最近一次更新后的数据模型集合生成待下发数据。
图5为根据本公开实施例的数据模型集合的组成结构示意图。如图5所示,分布式基站系统中包含5个子系统时,数据模型集合中便包含5个子系统的数据模型,即:子系统1的数据模型51、子系统2的数据模型52、子系统3的数据模型53、子系统4的数据模型54和子系统5的数据模型55,其中,每一个子系统的数据模型结构如图3所示。网元代理模块利用从每一个子系统中获取的子系统的数据模型组成数据模型集合,再将该数据模型集合发送至外部设备,使外部设备根据每一个子系统的数据模型生成通信原语,实现与每一个子系统的数据交互。
本公开实施例中,虽然网元代理模块的数据模型中只包括了子系统数据模型的类型信息,但数据模型集合中却包含了每一个子系统的数据模型的全部信息,外部设备基于数据模型集合中包含的子系统的全部信息,实现与分布式基站系统中所有子系统的数据交互。
根据本公开实施例,可以:为分布式基站中的每个子系统建立数据模型,其中,每个子系统的数据模型用于表征子系统的数据处理方式;分布式基站的所有子系统的数据模型中至少存在两个具有指定关系的数据模型,并且其中,指定关系为数据模型的类型信息相同但数据模型的版本信息不同;根据分布式基站的所有子系统的数据模型来建立网元代理模块的数据模型;网元代理模块的数据模型用于表征网元代理模块与分布式基站的每一个子系统的数据交互方式;根据网元代理模块的数据模型,通过网元代理模块来实现与多个子系统的数据交互,其中,网元代理模块为实现分布式基站系统与外部设备的数据交互的设备。
通过上述各实施例,可以为子系统建立类型信息相同但版本信 息不同数据模型,并根据网元代理模块的数据模型包含的数据交互方式,通过网元代理模块实现外部设备与分布式基站系统内每一个子系统的数据交互。如此,可以在分布式基站系统中为不同子系统配置类型信息相同但版本信息不同的数据模型,提高分布式基站系统中子系统数据模型配置的灵活性。
图6为根据本公开实施例的数据交互的方法的另一流程示意图。如图6所示,该方法包括:步骤61-65。
在步骤61,启动分布式基站系统。
示例性的,分布式基站系统的启动方法可以包括以下步骤:步骤611-步骤613。
在步骤611,每个子系统加载各自对应的数据模型。
在一个实施例中,在分布式基站系统启动之前每一个子系统内部都配置了各自的数据模型,启动系统时每个子系统加载各自对应的数据模型,形成如图3所示的模型,以实现子系统不同的功能。
在步骤612,网元代理模块加载对应的数据模型。
在一个实施例中,在分布式基站系统启动之前根据每一个子系统配置的数据模型,建立网元代理模块的数据模型,在系统启动时网元代理模块加载自身存储的数据模型,形成如图4所示的模型实例,以执行外部设备与数据交互任务。
在步骤613,网元代理模块读取每一个子系统的数据模型,生成数据模型集合。
在一个实施例中,网元代理模块读取每一个子系统的数据模型,组成如图5所示的数据模型集合,外部设备根据数据模型集合生成标准的通信原语,以符合现有的通信协议标准。
在步骤62,分布式基站系统中的网元代理模块将生成的数据模型集合发送至外部设备。
在步骤63,外部设备根据获取的数据模型集合生成待下发数据。
在步骤64,外部设备将待下发数据下发至对应的子系统中。
在一个实施例中,下发数据的步骤可以包括以下步骤:步骤641-步骤645。
在步骤641,外部设备将待下发数据发送至网元代理模块。
在步骤642,网元代理模块接收待下发数据后,判断待下发数据中是否包含子系统ID,如果是,执行步骤643,如果否,执行步骤645。
在一个实施例中,在待下发数据包含子系统ID的情况下,网元代理模块根据包含的子系统ID执行下发数据操作;在待下发数据中不包含子系统ID的情况下,网元代理模块将待下发数据发送至所有的子系统中。
在步骤643,网元代理模块解析待下发数据,将待下发数据拆分成多组数据。
在步骤644,根据每一组数据中包含的子系统ID,将每一组数据分别下发至对应的子系统中。
示例性的,下发数据为查询请求时,网元代理模块判断待下发数据中是否包含子系统ID,当包含时,查询对象是部分子系统,当不包含时,查询对象为全部子系统。
当查询对象为部分子系统时,待下发数据中包含待查询子系统的查询请求和子系统ID,网元代理模块解析待下发数据,并根据子系统ID将拆分后的数据发送至对应的子系统中;子系统响应查询请求,并向网元代理模块返回查询结果,网元代理模块将查询结果发送至外部设备。
当查询对象为全部子系统时,待下发数据可以不包含子系统ID,网元代理模块将查询请求发送至分布式基站系统的每一个子系统中,并将接收到的查询结果发送至外部设备。
示例性的,下发数据为控制命令时,下发数据中包含至少一个子系统ID。同样的,网元代理模块根据子系统ID将控制命令发送至对应的子系统中,子系统根据接收到的控制命令执行相应的操作,并向外部设备发送应答信息。
需要说明的是,由于分布式基站系统对外呈现为一个完整的系统,因此外部设备在下发数据时,需将多个子系统的待下发数据捆绑成一个事务,再将该事务发送至网元代理模块。网元代理模块在接收 到所述事务时,先进行拆分,然后下发至对应子系统中。
在步骤645,将待下发数据发送至每一个子系统中。
在步骤65,外部设备通过网元代理模块接收至少一个子系统的上报数据。
示例性的,当上报数据为与查询请求对应的查询结果时,上报的具体过程包括:步骤651-步骤653。
在步骤651,至少一个子系统根据接收到的查询请求,生成对应的上报数据。
在步骤652,子系统将生成的上报数据发送至网元代理模块。
在步骤653,网元代理模块将接收到的上报数据透传至外部设备中。
当子系统的数据模型改变时,子系统上报修改后的子系统的数据模型,上报的具体过程包括:步骤654-步骤656。
在步骤654,子系统将改变后的数据模型发送至网元代理模块。
在步骤655,网元代理模块将接收到的数据透传至外部设备中。
在步骤656,外部设备根据接收到的上报数据修改数据模型集合中对应子系统的数据模型。
需要说明的是,步骤63和步骤64为下发数据过程,步骤65为上报数据过程,上报数据和下发数据的先后顺序不受本公开实施例限制。
在本公开实施例中,示例性的给出了一种使用YANG建模语言对子系统进行建模而得到的子系统的数据模型,所述数据模型具有如下特点。
(1)每个子系统的数据模型都以统一的管理单元(Managed Element,ME)节点作为根节点,这里ME为本公开实施例中的分布式基站系统。ME根节点的标识信息为MEID,当多个子系统MEID相同时,代表多个子系统属于同一个分布式基站系统,ME节点只有一种实例。ME根节点定义可以包括:父节点:无,类型:单例,属性:MEID。
(2)ME根节点下为xxx子节点,xxx代表子系统的类型,一个子系统只有一个xxx子节点。xxx子节点中的属性信息包括: FunctionType(数据模型的类型信息,即xxx);FunctionVersion(数据模型的版本信息);FunctionId(子系统ID),xxx子节点存在多种实例。属性子节点的定义可以包括:父节点:MEID,类型:多例,属性:子系统ID、类型信息、版本信息。
(3)xxx子节点下包括子系统中所有的业务子节点,即所有的业务子节点在树结构中属于xxx子节点的下一级节点,业务子节点存在多种实例。业务子节点的定义可以包括:父节点:子系统ID,类型:多例,属性:业务数据。
需要说明的是,上述建模规则可以使用标准的YANG建模语言描述,每种类型的子系统允许有多个不同的模型版本,以FunctionVersion来区分不同版本信息。
网元代理模块的数据模型可以具有如下特点。
(1)网元代理模块的数据模型都以统一的ME节点作为根节点,ME根节点的标识信息为MEID,当多个子系统MEID相同时,代表多个子系统属于同一个分布式基站系统。ME根节点的定义包括:父节点:无,类型:单例,属性:MEID。
(2)ME根节点下为xxx子节点,xxx代表子系统的类型,一个网元代理模块中可以有多个xxx子节点,代表了分布式基站系统中包含的全部类型的网元代理模块的数据模型。xxx子节点中的属性信息包括:FunctionId(子系统ID),该FunctionId用于实现外部设备与分布式基站系统中子系统的数据交互。属性子节点的定义可以包括:父节点:MEID;xxx子节点1:类型:多例,属性:子系统1ID;xxx子节点2:类型:多例,属性:子系统2ID;xxx子节点3:类型:多例,属性:子系统3ID。
本公开实施例中,与YANG建模语言对应的Netconf通讯协议中,定义了外部管理设备和被管设备之间的配置数据访问接口,但是该协议只支持被管设备是简单节点的情况,不支持被管设备是多节点的情况(即被管设备由多个子系统组成)。在本公开实施例中,给出了一种多节点与管理设备的通信的方法,即通过网络代理模块实现外部设备与分布式基站系统中每一个子系统的通信。
为了能更加体现本公开的目的,在本公开上述实施例的基础上,以使用YANG建模语言建立子系统的数据模型和网元代理模块的数据模型,以Netconf通信协议实现外部设备与分布式基站系统的数据交互为例,进行进一步的举例说明。
Netconf是被管理设备和管理设备进行数据交互的标准协议,Netconf指定了很多数据交互时的操作原语。依照Netconf通信协议定义的一些关键的数据交互原语如下:a)外部设备:user;b)网元代理模块:NeAgent;c)子系统1:nf1;d)子系统x:nfx。另外,在各个过程中可以使用的原语还可以包括:
1、配置待下发数据edit-config:一个edit-config原语做成一个事务,在进行数据交互时,该事务的执行结果为:全部成功或者全部回滚。执行流程如下:
(1)user->NeAgent:edit-config(nfdata)
(2)解析nfdata,分解成nf1data至nfxdata
(3)NeAgent->nf1:Lock()
(4)NeAgent->nfx:Lock()
(5)NeAgent->nf1:edit-config(nf1data)
(6)NeAgent->nf2:edit-config(nf2data)
(7)If(nf1or nf2 failute):rollback()
(8)NeAgent->nf1:Commit()
(9)NeAgent->nf2:Commit()
(10)NeAgent->nf1:Unlock()
(11)NeAgent->nf2:Unlock()
(12)NeAgent->user:edit-config reply()
2、配置上报数据Notification:在远程过程调用协议(Remote Procedure Call Protocol,RPC)定义中,规定第一个参数就是子系统的ID,根据数据中的第一个参数来区分不同子系统上报的数据。
3、Lock、unlock(锁定/解锁定网元数据):本公开实施例中可以增加子系统ID参数,实现对某一种数据模型的锁定。如:Lock(子系统ID)、Unlock(子系统ID)。
4、Delete-config,意味着删除一套数据模型。
5、Close-session、kill-session,意味着结束一个Netconf会话。
为了能更加体现本公开的目的,在本公开上述实施例的基础上,进行进一步的举例说明。
本公开实施例中,可以对子系统的数据模型进行单独修改,而不影响分布式基站系统中其他子系统的正常工作。
示例性的,可以将图1中子系统4的数据模型b从版本v1升级到版本v3,版本v3中增加了属性A,同时子系统4的数据模型随之改变。
在这种情况下,网元代理模块的数据模型不变。由于网元代理模块的数据模型只包括子系统4的ID和数据模型的类型信息,因此,当子系统4的数据模型的版本信息改变时,网元代理模块的数据模型保持不变。
在这种情况下,其他子系统的数据模型不变,特别是相邻的子系统3,其数据模型仍为模型b版本v1,不受系统4的影响。
在这种情况下,模型数据集合发生变化,新增了模型b的v3版本。
外部设备与子系统4进行数据交互时,可以根据改变后子系统4的数据模型实现与子系统4的数据交互。
子系统4的数据模型的修改过程如下:1、nfx.upgrade(model b,v1->v3);2、nfx->neAgent.virtualModelContainer.add(v3);3、User->neAgent.operation(nfx,v3data)。
在本公开实施例中,分布式基站系统中每一个子系统各自独立互不影响,可以对每一个子系统进行控制,如:对某一个子系统的数据模型进行升级操作时,不影响整个系统的正常工作,提高分布式基站系统中子系统配置的灵活性。
本公开实施例还提供了一种数据交互的装置。图7为根据本公开实施例的数据交互装置的组成结构示意图。
数据交互装置70包括:第一建立模块701、第二建立模块702 和控制模块703。
所述第一建立模块701设置为为分布式基站中的每个子系统建立数据模型,其中,每个子系统的数据模型用于表征子系统的数据处理方式,分布式基站的所有子系统的数据模型中至少存在两个具有指定关系的数据模型,并且其中,指定关系为数据模型的类型信息相同但数据模型的版本信息不同。
所述第二建立模块702设置为根据分布式基站的所有子系统的数据模型来建立网元代理模块的数据模型,其中,网元代理模块的数据模型用于表征网元代理模块与分布式基站的每一个子系统的数据交互方式。
所述控制模块703设置为根据网元代理模块的数据模型,通过网元代理模块来实现与多个子系统的数据交互。
所述网元代理模块为实现分布式基站与外部设备的数据交互的设备。
