Description

资源管理方法、设备及*** 技术领域
本申请涉及通信技术领域，尤其涉及资源管理方法、设备及***。
背景技术
现有技术中，***(4th generation，4G)网络的接入设备和第五代(5th generation，5G)网络的接入设备都是通过流控制传输协议(stream control transmission protocol，SCTP)与核心网中的移动管理网元建立链接后，再通过专有流程发起应用层协议的建链。比如，4G网络中的接入设备通过SCTP与核心网中的移动管理实体(mobility management entity，MME)建立链接后，再通过4G网络中的S1建立(setup)流程发起S1应用层协议(S1 application protocol，S1AP)的建链；或者，5G网络中的接入设备通过SCTP与核心网中的接入和移动性管理功能(access and mobility management function，AMF)网元)建立链接后，再通过5G网络中的下一代网络(next generation，NG)建立流程)发起NG应用层协议(NG application protocol，NGAP)的建链。
目前，接入设备和移动管理网元之间的链接断开是通过SCTP偶联(assoc)中断来实现的。然而，由于SCTP偶联中断可能是接入设备的主动断链引起(比如操作维护)，也可能是接入设备和移动管理网元之间的底层传输网络中断引起，因此，移动管理网元无法确定和接入设备之间的链路断开的原因是真的底层传输网络异常导致还是人为操作引起，一旦移动管理网元和接入设备之间的链路断开，即进行接入设备的链路故障告警。同时，为了避免底层传输网络不稳定引起的告警频繁而影响接入设备正常维护的问题，移动管理网元需要在接入设备的链路发生故障时暂时缓存故障接入设备的信息，以此来对底层传输网络不稳定引发的接入设备的链路故障告警做抑制处理。
但是，按照上述方式，对于接入设备主动断链的场景，在接入设备发生改变(比如组网调整)的情况下，一方面，调整后的接入设备可能会由于移动管理网元的资源限制而无法成功或快速接入到该移动管理网元上；另一方面，调整后的接入设备通常会使用调整前的接入设备的信息尝试接入到该移动管理网元，这将导致调整后的接入设备的信息和移动管理网元上保存的故障接入设备的信息产生冲突，进而可能导致调整后的接入设备无法成功接入到该移动管理网元上。
因此，如何在接入设备主动断链的场景下，使得调整后的接入设备成功快速的接入到相应的移动管理网元上，是目前亟待解决的问题。

移动管理网元接收来自接入设备的关闭消息；移动管理网元根据该关闭消息，释放该目标SCTP偶联对应的SCTP层资源和该接入设备对应的应用层资源。基于该方案，由于移动管理网元可以接收来自接入设备的关闭消息，并根据该关闭消息，释放该目标SCTP偶联对应的SCTP层资源和该接入设备对应的应用层资源。因此，对于接入设备主动断链的场景，在接入设备发生改变(比如组网调整)的情况下，一方面，可以避免调整后的接入设备可能会由于移动管理网元的资源限制而无法成功或快速接入到该移动管理网元上的问题；另一方面，可以避免调整后的接入设备使用调整前的接入设备的信息尝试接入到该移动管理网元，从而导致调整后的接入设备的信息和移动管理网元上保存的故障接入设备的信息产生冲突，进而可能导致调整后的接入设备无法成功接入到该移动管理网元上的问题。也就是说，基于本申请实施例提供的资源管理***，对于接入设备主动断链的场景，在接入设备发生改变(比如组网调整)的情况下，可以使得调整后的接入设备成功快速的接入到相应的移动管理网元上。

示例性的，该关闭消息可以为shutdown消息。

S502、NG-AN设备向AMF网元发送释放指示消息，以使得AMF网元接收来自NG-AN设备的释放指示消息。其中，该释放指示消息用于释放该NG-AN设备对应的NGAP层资源。
示例性的，如图5所示，本申请实施例中，NG-AN设备向AMF网元发送NG释放指示消息可以包括：NG-AN设备的NGAP层向AMF网元的NGAP层发送NG释放指示消息，本申请实施例对此不作具体限定。
示例性的，如图5所示，本申请实施例中的释放指示消息可以为NG释放指示(NG release indication)消息，本申请实施例对此不作具体限定。

S503、AMF网元根据释放指示消息，释放NG-AN设备对应的NGAP层资源。
示例性的，如图5所示，本申请实施例中，可以是AMF网元的NGAP层接收来自NG-AN设备的NGAP层的释放指示消息之后，释放NG-AN设备对应的NGAP层资源，本申请实施例对此不作具体限定。
此外，本申请实施例中，在NG-AN设备接收到维护命令之后，对于该NG-AN设备对应的每一条SCTP偶联，NG-AN设备的NGAP层还可以以SCTP优雅断链方式调用应用平台接口(application platform interface，API)以释放对应的SCTP偶联，比如图5中NG-AN设备的NGAP层向NG-AN设备的SCTP层发送SCTP偶联释放指示，本申请实施例对此不作具体限定。进而，在NG-AN设备的SCTP层根据协议进行相关处理后，对于该NG-AN设备对应的每一条SCTP偶联，本申请实施例提供的资源管理方法还可以包括如下步骤S504-S507：
S504、NG-AN设备向AMF网元发送关闭消息，以使得AMF网元接收来自NG-AN设备的关闭消息。
示例性的，如图5所示，NG-AN设备向AMF网元发送关闭消息可以包括：NG-AN设备的SCTP层向AMF网元的SCTP层发送关闭消息，本申请实施例对此不作具体限定。

示例性的，如图5所示，AMF网元根据关闭消息，释放目标SCTP偶联对应的SCTP层资源可以包括：AMF网元的SCTP层根据关闭消息，释放目标SCTP偶联对应的SCTP层资源。
需要说明的是，本申请实施例中，AMF网元的SCTP层接收到来自NG-AN设备的SCTP层的关闭消息之后，并不会立即将该目标SCTP偶联对应的SCTP层资源全部释放，而是可以继续处理已经接收到的AMF网元的NGAP层发送但未确认的数据(比如将已经接收到的AMF网元的NGAP层发送但未确认的数据发送给NG-AN设备的SCTP层，由NG-AN设备的SCTP层将该数据发送给NG-AN设备的NGAP层)，但不接收AMF网元的NGAP层新发送的数据。其中，在AMF网元接收来自NG-AN设备的关闭完成消息(即下述步骤S507)之后，才能将目标SCTP偶联对应的SCTP层资源全部释放，在此统一说明，以下不再赘述。
可选的，如图5所示，本申请实施例中，AMF网元的SCTP层接收到来自NG-AN设备的SCTP层的关闭消息之后，还可以通过回调等方式通知AMF网元的NGAP层目标SCTP偶联将要被关闭，比如图5中AMF网元的SCTP层向AMF网元的NGAP层发送SCTP偶联释放通知。进而，在AMF网元的NGAP层接收来自AMF网元的SCTP层的SCTP偶联释放通知之后，在AMF网元NGAP层还包括NG-AN设备对应的NGAP层资源的情况下，AMF网元的NGAP层释放NG-AN设备对应的NGAP层资源。或者，可选的，在AMF网元的NGAP层接收来自AMF网元的SCTP层的SCTP偶联释放通知之后，在AMF网元NGAP层还包括NG-AN设备对应的NGAP层资源，且该目标SCTP偶联为该NG-AN设备对应的最后一条SCTP偶联的情况下，AMF网元的NGAP层释放NG-AN设备对应的NGAP层资源，本申请实施例对此不作具体限定。
需要说明的是，本申请实施例中，AMF网元释放目标SCTP偶联对应的SCTP层资源与AMF网元的SCTP层向AMF网元的NGAP层发送SCTP偶联释放通知之间没有必然的执行先后顺序，可以是先执行AMF网元释放目标SCTP偶联对应的SCTP层资源，再执行AMF网元的SCTP层向AMF网元的NGAP层发送SCTP偶联释放通知；也可以是先执行AMF网元的SCTP层向AMF网元 的NGAP层发送SCTP偶联释放通知，再执行AMF网元释放目标SCTP偶联对应的SCTP层资源；也可以是同时执行AMF网元释放目标SCTP偶联对应的SCTP层资源与AMF网元的SCTP层向AMF网元的NGAP层发送SCTP偶联释放通知，本申请实施例对此不作具体限定。
S506、AMF网元向NG-AN设备发送关闭应答消息，以使得NG-AN设备接收来自AMF网元的关闭应答消息。
示例性的，如图5所示，AMF网元向NG-AN设备发送关闭应答消息可以包括：AMF网元的SCTP层向NG-AN设备的SCTP层发送关闭应答消息，本申请实施例对此不作具体限定。

示例性的，本申请实施例中的关闭完成消息例如可以是shutdown complete消息，本申请实施例对此不作具体限定。
进一步的，在无线网络组网调整后，NG-AN设备可以重新向AMF网元发起SCTP偶联建立，使得AMF网元按照新SCTP偶联建立方式和NG-AN设备完成SCTP偶联的建立偶联的建立(如图5中的步骤S508)。在SCTP偶联建立后，NG-AN设备可以通过SCTP偶联发起NG建立流程。其中，由于AMF网元上没有故障NG-AN设备的信息，因此可以按照新接入AMF网元的方式顺利完成NG建立流程(如图5中的步骤S509)。其中，SCTP偶联建立流程以及NG建立流程可参考现有的实现方式，在此不予赘述。
基于本申请实施例提供的资源管理方法，对于NG-AN设备主动断链的场景，在NG-AN设备发生改变(比如组网调整)的情况下，通过对AMF网元上的资源进行管理(比如释放AMF网元上的NG-AN设备对应的应用层资源)，可以使得调整后的NG-AN设备成功快速的接入到相应的AMF网元上，相关技术效果分析可参考上述资源管理***部分，在此不再赘述。
其中，上述步骤S501至S509中的NG-AN设备或者AMF网元的动作可以由图4所示的通信设备400中的处理器401调用存储器403中存储的应用程序代码来执行，本实施例对此不作任何限制。
可选的，以图1所示的资源管理***应用于如图3所示的5G网络，NG-AN设备和AMF网元之间不支持应用层资源释放流程，应用层为NGAP层为例，如图7所示，为本申请实施例提供的一种资源管理方法，该资源管理方法包括如下步骤：
S701、同图5所示的实施例中的步骤S501，相关描述可参考图5所示的实施例，在此不再赘述。
其中，在NG-AN设备接收到维护命令之后，对于该NG-AN设备对应的每一条SCTP偶联，NG-AN设备的NGAP层还可以以SCTP优雅断链方式调用API以释放对应的SCTP偶联，比如图7中NG-AN设备的NGAP层向NG-AN设备的SCTP层发送SCTP偶联释放指示，本申请实施例对此不作具体限定。进而，在NG-AN设备的SCTP层根据协议进行相关处理后，对于该NG-AN设备对应的每一条SCTP偶联，本申请实施例提供的资源管理方法还可以包括如下步骤S702-S705：
S702、同图5所示的实施例中的步骤S504，相关描述可参考图5所示的实施例，在此不再赘述。
其中，在AMF网元接收来自NG-AN设备的关闭消息之后，可以根据该关闭消息，释放目标SCTP偶联对应的SCTP层资源和NG-AN设备对应的NGAP层资源，本申请实施例示例性的以如下步骤S703a-S703c为例进行说明：
S703a、AMF网元的SCTP层根据关闭消息，释放目标SCTP偶联对应的SCTP层资源。
S703b、AMF网元的SCTP层向AMF网元的NGAP层发送SCTP偶联释放通知，以使得AMF网元的NGAP层接收来自AMF网元的SCTP层的SCTP偶联释放通知。
S703c、AMF网元的NGAP层释放NG-AN设备对应的NGAP层资源。
可选的，本申请实施例中，AMF网元的NGAP层释放NG-AN设备对应的NGAP层资源可以包括：在目标SCTP偶联为该NG-AN设备对应的最后一条SCTP偶联的情况下，AMF网元的NGAP层释放NG-AN设备对应的NGAP层资源。
需要说明的是，本申请实施例中，在释放某条SCTP偶联对应的SCTP层资源时，AMF网元的NGAP层接收来自AMF网元的SCTP层的SCTP偶联释放通知之后，若NG-AN设备对应的NGAP层资源已经被释放，或者目标SCTP偶联不是该NG-AN设备对应的最后一条SCTP偶联，则可以不用执行步骤S703c，对于某条SCTP偶联，步骤S703c是可选的，在此统一说明，以下不再赘述。
其中，步骤S703a-S703c的详细说明可参考图5所示的实施例中的步骤S505，在此不再赘述。
S704-S707、同图5所示的实施例中的步骤S506-S509，相关描述可参考图5所示的实施例，在此不再赘述。
基于本申请实施例提供的资源管理方法，对于NG-AN设备主动断链的场景，在NG-AN设备发生改变(比如组网调整)的情况下，通过对AMF网元上的资源进行管理(比如释放AMF网元上的NG-AN设备对应的应用层资源)，可以使得调整后的NG-AN设备成功快速的接入到相应的AMF网元上，相关技术效果分析可参考上述资源管理***部分，在此不再赘述。
其中，上述步骤S701至S707中的NG-AN设备或者AMF网元的动作可以由图4所示的通信设备400中的处理器401调用存储器403中存储的应用程序代码来执行，本实施例对此不作任何限制。
可选的，图5或图7所示的资源管理方法以图1所示的资源管理***应用于如图3所示的5G网络，应用层为NGAP层为例进行说明。当然，本申请实施例提供的资源管理方法也可以以图1所示的资源管理***应用于如图2所示的4G网络，应用层为S1AP层为例进行说明。该场景下，仅需将图5或图7所示的实施例中的AMF网元替换为本申请实施例中的MME，将图5或图7所示的实施例中的NG-AN设备替换为本申请实施例中的E-UTRAN设备，将图5或图7所示的实施例中的NG接口替换为本申请实施例中的S1接口，将图5或图7所示的实施例中的NG-C接口链路命令替换为本申请实施例中的S1-C接口链路命令，将图5或图7所示的实施例中的NG释放指示消息替换为本申请实施例中的S1释放指示消息，将图5或图7所示的实施例中的NGAP替换为本申请实施例中的S1AP层，等等，相关描述可参考图5或图7所示的实施例，在此不再赘述。
上述主要从各个网元之间交互的角度对本申请实施例提供的方案进行了介绍。可以理解的是，上述接入设备或者移动管理网元为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设 计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。

比如，以采用集成的方式划分各个功能模块的情况下，图8示出了一种移动管理网元80的结构示意图。该移动管理网元80包括：收发模块802和处理模块801。
一种可能的实现方式中：
收发模块802，用于接收来自接入设备的释放指示消息；处理模块801，用于根据释放指示消息，释放接入设备对应的应用层资源。

可选的，发送模块902，还用于向移动管理网元发送关闭消息，关闭消息用于指示移动管理网元释放目标流控制传输协议SCTP偶联。
其中，上述方法实施例涉及的各步骤的所有相关内容均可以援引到对应功能模块的功能描述，在此不再赘述。
在本实施例中，该接入设备90以采用集成的方式划分各个功能模块的形式来呈现。这里的“模块”可以指特定ASIC，电路，执行一个或多个软件或固件程序的处理器和存储器，集成逻辑电路，和/或其他可以提供上述功能的器件。在一个简单的实施例中，本领域的技术人员可以想到该接入设备90可以采用图4所示的形式。
