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描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本公开保护的范围。
本公开的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本公开的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
为了便于理解本公开的技术方案,下面介绍分布式自治的6G系统架构。
6G网络发展的重要趋势是集中与分布式的网络架构。5G以及前几代的网络架构原生设计是集中式控制的,随着网络的发展,面向业务发展与技术发展的双驱动力,6G网络的设计需考虑分布式的架构,如图1所示,其控制面向分布式逐渐演进。
6G网络将面向空、天、地、海多样化场景与网络性能需求,集中式的网络架构无法统一满足所有场景。为应对这一挑战,6G网络架构需要超越集中控制,逐步向分布式架构演进,将更多的网络功能扩展到网络边缘,构建分布式的具有不同功能等级的分布式同构微云单元(Small Cloud Unit,SCU),每个分布式单元(或者称为分布式网络节点)都是自包含的,具有完整的控 制和数据转发的所有功能。多个微云单位跨域根据业务需求组成自治的微型网络,根据特定的业务场景、用户规模、地理环境等要求有针对性的提供网络服务。
当前单节点的用户面路径构建方法无法很好地适用于分布式网络场景。主要缺点是:
(1)分布式网络的用户面路径,会涉及到位于不同分布式节点的用户面功能,不同节点之间的会话管理功能可能无法控制或发现其他节点内所有用户面功能及其相关信息,会造成分布式网络节点之间的用户面路径的构建存在挑战。
(2)如果在每个节点内独立完成域内用户面功能的选择并通过控制面消息完成信息交互,可能无法构建最优用户面路径,而且会造成用户面路径构建开销大的问题。
本公开的实施例提供了一种用户面路径构建方法、装置、网络节点,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,重复之处不再赘述。
本文中的节点也可以称为分布式网络节点,比如,第一节点也可以称为第一分布式网络节点,第二节点也可以称为对端节点或者第二分布式网络节点。
参见图2,本公开实施例提供一种分布式网络用户面路径构建方法,应用于第一节点,具体步骤包括:步骤201和步骤202。
步骤201:建立第一节点的第一跨域用户面功能和第二节点的第二跨域用户面功能之间的跨域用户面路径;
本实施例中,第一节点中可以有一个或多个跨域用户面功能,第二节点中可以有一个或多个跨域用户面功能。
跨域用户面功能是一种可以被其他分布式网络节点控制或发现的特殊用户面功能,例如,跨域用户面功能的服务范围更大或转发性能更高等。
步骤202:建立所述第一节点的第一跨域用户面功能和所述第一节点的除所述第一跨域用户面功能之外的用户面功能之间的域内用户面路径。
需要说明的是,在本实施例中不限定步骤201和步骤202的先后顺序, 也就是,可以先执行步骤201再执行步骤202,或者也可以先执行步骤202再执行步骤201,或者同时执行步骤201和步骤202。
可以理解的是,本实施例可以适用于以下两种场景:
场景1:第一节点(不区分与其连接的节点情况)存在一个或多个跨域用户面功能,当其他节点需要与该第一节点之间构建跨域用户面路径时,该第一节点根据对端节点信息(例如位置)、用户面功能的负载信息、策略信息等中的至少一项,选择一个跨域用户面功能,作为其与其他节点构建用户面路径的一部分。
场景2:第一节点和与其直接相连的集中节点和/或邻居节点之间分别存在一个或多个与其他节点对应的跨域用户面功能。当需要与该节点之间构建用户面路径时,根据对端节点标识、用户面功能的负载信息、策略信息等中的至少一项,选择一个与对端节点对应的跨域用户面功能作为用户面路径的一部分。
可以理解的是,场景1与场景2的区别是,场景1是不区分与其连接的节点设置跨域用户面功能,场景2是针对与其连接的节点设置跨域用户面功能。

为了更好的理解本公开的实施方式,下面结合实施例1~实施例3进行介绍。
实施例1:
实施例1.1:每个分布式网络节点存在一个跨域用户面功能,如图4所示。
分布式网络节点1包括会话管理功能、用户面功能和跨域用户面功能,分布式网络节点2包括会话管理功能、用户面功能和跨域用户面功能,可以理解的是,图中分布式网络节点1和分布式网络节点2的用户面功能、跨域用户面功能的数量可以是一个或多个,即对分布式网络节点1和分布式网络节点2的用户面功能、跨域用户面功能的数量的数量不做限定。
当涉及到构建分布式网络节点1和分布式网络节点2之间的用户面路径时,分别在分布式网络节点1和分布式网络节点2内选择其节点内的跨域用户面功能,并在这两个跨域用户面功能之间建立路径。
其中,两个跨域用户面功能之间的路径建立方法可以是分配和交换用户面隧道信息,或者也可以网际协议(Internet Protocol,IP)路由方式,这里不作限定。
进一步地,针对分配和交换用户面隧道信息的方法,可以是通过用户面消息直接交换,或者也可以是通过控制面消息交换。对于控制面消息交换的方法,根据控制面网络功能与用户面功能的权限问题,可能涉及一个分布式网络节点上的一个会话管理功能,也可能涉及两个分布式网络节点上两个会话管理功能。
其中,跨域用户面功能,可以作为会话管理功能的本地配置的信息,或者也可以作为用户面功能的一种能力,比如,上行分流器(Uplink Classifier,UL CL),协议数据单元会话锚点(PDU Session Anchor,PSA),域间(Interdomain)路由,简单转发(simple forwarder)等。当跨域用户面功能作为一种能力存在时,可以在会话管理功能选择用户面功能时,通过该能力完成筛选;或者,用户面功能(User Plane Function,UPF)服务化,通过网络存储功能(Network Repository Function,NRF)发现UPF时,可以将跨域能力作为其中一个请求参数。
跨域用户面功能的配置,可以基于部署位置(例如多邻居节点距离最近),或者是基于特定能力(例如更高的转发性能),或者是根据运营商的策略。
然后,在分布式网络节点1和分布式网络节点2内,根据单节点内的用户面路径构建方法完成域内的用户面路径构建。从而,完成跨域的用户面路径构建。
实施例1.2:每个分布式网络节点存在多个跨域用户面功能,如图5所示。
该实施例与实施例1.1的区别是,在一个分布式网络节点内存在多个跨域用户面功能,需要在多个跨域用户面功能中选择一个。
跨域用户面功能的选择,可以基于以下至少之一:用户面功能的负载、第一节点的部署位置、第二节点的部署位置、用户面功能的跨域能力、本地配置的跨域信息、锚点能力、数据网络接入标识(DN Access Identifier,DNAI)信息等,选择负载较小、距离第二节点更近的跨域用户面功能。例如,通过NRF发现时,可以将跨域能力和/或第二节点标识作为其中的请求参数。
实施例1.3:每个分布式网络节点与其直接相连的节点分别有一个跨域用户面功能。
该实施例与实施例1.1的区别是,跨域用户面功能的选择与第二节点是对应的。
如图6所示,分布式网络节点2存在与分布式网络节点1和分布式网络节点3分别对应的跨域用户面功能。
跨域用户面功能可以作为会话管理功能本地配置的信息,当会话管理功能需要执行用户面功能选择以构建跨域用户面路径时,通过第二节点的节点 标识信息,在本地配置信息中匹配到用于第二节点的跨域用户面功能。
跨域用户面功能也可以作为用户面功能的一种跨域能力,通过跨域能力和节点标识等完成该跨域用户面功能的选择。
需要说明的是,实施例1.3是针对与其直接相连分布式网络节点对应设置跨域用户面功能,指的是跨域用户面功能设置的粒度,但不排除一个跨域用户面功能是针对2个相连分布式网络节点设置的场景。
实施例1.4:每个分布式网络节点为与其直接相连的节点分别有多个跨域用户面功能。
该实施例与实施例1.3的区别是,在一个分布式网络节点内存在与第二节点相关的多个跨域用户面功能,需要在多个跨域用户面功能中选择一个。
可以基于用户面功能负载、第二节点的部署位置等中的至少一项,优先选择用户面功能负载较小、距离第二节点的跨域用户面功能较近的跨域用户面功能。
实施例2:用户面路径建立流程
实施例2.1:基于控制面消息交换用户面信息,可控制跨域用户面功能
参见图7,具体步骤如下:
步骤1a:节点1的会话管理功能执行跨域用户面功能1的选择,以及第二节点的跨域用户面功能2的选择;
其中,节点内跨域用户面功能的选择可以参考实施例1中的描述。
第二节点跨域用户面功能的选择也类似,如果会话管理功能1中配置或通过NRF发现了节点2的跨域用户面功能,基于本节点的信息、用户面功能的负载等完成节点2的跨域用户面功能的选择。
步骤1b:如果步骤1a中选择的节点内跨域用户面功能无法充当接入网(Access Network,AN)侧用户面功能,则继续执行用户面功能选择;
步骤2:依次构建跨域用户面路径和节点1内的域内用户面路径;
步骤2a:会话管理功能1和跨域用户面功能1之间交互会话建立请求和响应;
步骤2b:会话管理功能1和跨域用户面功能2之间交互会话建立请求和响应;
步骤2c:会话管理功能1和跨域用户面功能1之间交互会话修改请求和响应;
步骤2d:域内用户面路径建立;
步骤3:会话管理功能1与会话管理功能2交互,请求创建会话,携带选择的跨域用户面功能2的相关信息;
可选地,跨域用户面功能2的相关信息包括跨域用户面功能2的名称、跨域用户面功能2的地址、报文匹配和转发规则、QoS规则等中的至少一项;
步骤4:如果所选的跨域用户面功能2无法充当接入数据网络(Data Network,DN)的锚点,则继续执行用户面功能选择;
步骤5:如果步骤4选择了用户面功能,则完成节点2域内用户面路径建立;
步骤6:创建会话响应。
实施例2.2:基于控制面消息交换用户面信息,可发现跨域用户面功能。
该实施例与实施例2.1的主要区别是,跨域用户面功能2相关的信息交互由会话管理功能2执行。
参见图8,具体步骤如下:
步骤1a:节点1的会话管理功能1执行跨域用户面功能1的选择;
步骤1b:节点1的会话管理功能1执行用户面功能的选择;
步骤2:构建节点1内的域内用户面路径;
步骤2a:会话管理功能1和跨域用户面功能1之间交互会话建立请求和响应;
步骤2b:域内用户面路径建立;
在本实施例中,不涉及跨域用户面功能1跨域用户面功能2之间的交互;
步骤3:会话管理功能1与会话管理功能2交互,请求创建会话,携带选择的跨域用户面功能1的相关信息,跨域用户面功能1相关信息包括跨域用户面功能1的名称、跨域用户面功能1的地址、跨域用户面功能1的隧道信息等中的至少一项;
步骤4a:会话管理功能2基于步骤3中的信息和本地信息选择跨域用户面功能2;
步骤4b:如果所选的跨域用户面功能2无法充当接入DN的锚点,则继续执行用户面功能选择;
步骤5a:会话管理功能2与跨域用户面功能2交互,完成报文匹配和转发规则下发、QoS规则下发;
步骤5b:域内用户面路径建立;
步骤6:会话管理功能1向会话管理功能2发送创建会话响应,会话响应包括跨域用户面功能2的隧道信息。
步骤7:会话管理功能1将收到的跨域用户面功能2相关的用户面信息发送给跨域用户面功能1。
实施例2.3:基于用户面消息交换用户面信息,跨域可控制。
该实施例与实施例2.1的主要区别是,基于用户面消息交换用户面信息。
参见图9,具体步骤如下:
步骤1a:节点1的会话管理功能1执行跨域用户面功能1的选择,以及第二节点的跨域用户面功能2的选择;
其中,节点1内跨域用户面功能1的选择如实施例1所述;
第二节点的跨域用户面功能2的选择也类似,如果会话管理功能1中配置或通过NRF发现了节点2的跨域用户面功能,基于本节点的信息、负载等完成第二节点跨域用户面功能的选择。
步骤1b:如果步骤1a中选择的节点内跨域用户面功能无法充当AN侧用户面功能,则继续执行用户面功能选择;
步骤2:依次基于用户面消息交换用户面路径信息的方法构建用户面路径。
步骤2a:会话管理功能1向用户面功能1、跨域用户面功能1和跨域用户面功能2发送会话建立请求;
步骤2b:跨域用户面功能1和跨域用户面功能2之间通过用户面消息交换用户面路径信息;
步骤2c:跨域用户面功能1、用户面功能1和跨域用户面功能2向会话管理功能1发送会话建立响应;
步骤3:会话管理功能1与会话管理功能2交互,请求创建会话,携带 跨域用户面功能1和跨域用户面功能2的相关信息;
可选地,跨域用户面功能1相关信息包括跨域用户面功能1的名称、跨域用户面功能1的地址、跨域用户面功能1的隧道信息等中的至少一项。
