为了解决移动边缘计算中由于接入点变化带来的应用数据丢失问题,本公开提供了一种移动边缘计算中路径切换方法、移动边缘计算平台及网关,以下结合附图以及实施例,对本公开进行进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本公开,并不限定本公开。
为了更好的理解本公开实施例,以下对移动边缘计算进行简要描述。
ETSI(European Telecommunications Standards Institute,欧洲电信标准化协会)MEC工作组定义了移动边缘计算的架构,如图1所示,在该架构中,包括OperationsSupporting System:运营支撑系统;UserAPP LCM Proxy:用户应用生命周期管理网关;Mobile edge Orchestrator:移动边缘编排器;CFS Portal:面向用户的终端入口;ME platform Element management:移动边缘平台网元管理;ME app rules&reqtsmgmt:移动边缘应用规则需求管理;ME app lifecycle mgmt:移动边缘应用生命周期管理;Mobile edge platform manager:移动边缘平台管理;Virtualisation Infrastructure Manager:虚拟资源管理器;Mobile Edge host:移动边缘宿主机;traffic rules Control:流量规则控制;DNShandling:DNS处理;Service Registry:服务注册;ME Service:移动边缘服务;其中,移动边缘宿主(MEH,Mobile Edge Host)包括虚拟架构(Virtualization Infrastructure),其上有数据转发功能(DP,Data Plane)。在移动边缘宿主上还驻留着一个移动边缘平台(MEP,Mobile Edge Platform)和若干移动边缘应用(MEA,Mobile Edge Application)。
移动边缘平台为移动边缘应用提供若干移动边缘业务(MES,Mobile Edge Service)。移动边缘平台为了支持移动边缘应用和移动边缘业务间的通信,移动边缘平台中包含了业务注册功能(Service Registry),该功能提供发布注册机制,用于移动边缘业务发布业务和移动边缘应用签约移动边缘业务。移动边缘平台还为应用提供DNS(Domain Name System,域名系统)功能,以便应用能将自己的IP地址与FQDN(Fully Qualified Domain Name,完全合格域名/全称域名)注册到DNS服务器中。移动边缘平台中的流量规则控制(Traffic Rule Control)可以控制数据转发功能的转发规则,从而能对流经移动边缘宿主的流量进行重定向,比如,将某个业务流的流量重定向到位于移动边缘宿主上的移动边缘应用。
移动边缘编排器(MEO,Mobile Edge Orchestrator)负责移动边缘应用的生命周期管理、移动边缘平台的配置、移动边缘平台的选择等。OSS(Office of Strategic Services,运营支撑系统)提供了与第三方的接口,从而可以允许第三方将移动边缘应用加载到移动边缘系统,并触发移动边缘应用的实例化和实例终结等。移动边缘平台管理器(MEPM,Mobile Edge Platform Manager)负责配置移动边缘平台和移动边缘应用的生命周期管理,比如,将移动边缘应用对应的流量规则和DNS规则配置到移动边缘平台、从虚拟化管理器(Virtualization Infrastructure Manager)中申请资源,并加载相应的移动边缘应用。虚拟化管理器负责移动边缘宿主中虚拟化架构(Virtualization Infrastructure)的虚拟资源的管理,分配虚拟资源,加载移动边缘应用软件包等。
移动边缘宿主之间的接口Mp3用于支持由于用户移动引起的跨移动边缘宿主间的通信,比如,支持用户移动后在新旧平台间交互信令以保持移动终端与驻留在源移动边缘宿主上的应用间的通信链路等。
在移动网络中,由于移动终端具有移动性,移动终端可能会移出源移动边缘宿主的覆盖范围,而此时,移动终端通信的应用实例仍然驻留在源移动边缘宿主上,此时,终端针对源移动边缘计算平台的上行数据,就会丢失;源移动边缘计算平台针对终端的下行数据也会丢失。
基于此,如图2所示,本公开实施例中一种移动边缘计算中路径切换方法,包括:
S201,在终端接入源接入点后,源移动边缘计算平台从所述源接入点接收上行数据;所述上行数据具体为所述终端针对所述源移动边缘计算平台发送的数据;
S202,在终端从源接入点切换到目的接入点后,所述源移动边缘计算平台从目的移动边缘计算平台接收所述上行数据。
移动边缘计算中在终端接入源接入点后,终端与源移动边缘计算平台上的应用实例之间的上行数据的传输路径为终端-源接入点-源移动边缘计算平台;在终端从源接入点切换到目的接入点后,终端与源接入点断开,因此上行数据就会丢失,而本公开实施例中方法在终端从源接入点切换到目的接入点后,通过从目的移动边缘计算平台接收所述上行数据,也就是说,将上述传输路径切换为终端-目的接入点-目的移动边缘计算平台-源移动边 缘计算平台,从而可以有效保持移动终端与驻留在源移动边缘宿主上的应用实例间的通信畅通,有效解决移动边缘计算中由于接入点变化带来的上行数据丢失问题,并有效保持了移动边缘计算网络中业务连续性。
进一步说,所述源移动边缘计算平台与所述目的移动边缘计算平台连接。也就是说,目的移动边缘计算平台相对于源移动边缘计算平台之间是可见的,两者之间具有通讯连接关系。
在上述实施例的基础上,进一步提出上述实施例的变型实施方式,在此需要说明的是,为了使描述简要,在各变型实施方式中仅描述与上述实施例的不同之处。
在本公开实施例的一个实施方式中,在终端接入源接入点后,所述源移动边缘计算平台将下行数据发送给所述源接入点,以使所述源接入点将所述下行数据发送给所述终端;所述下行数据具体为所述源移动边缘计算平台针对所述终端发送的数据;
在终端从源接入点切换到目的接入点后,所述源移动边缘计算平台将所述下行数据发送给所述目的移动边缘计算平台,以使所述目的移动边缘计算平台将所述下行数据经所述目的接入点发送给所述终端。
移动边缘计算中在终端接入源接入点后,终端与源移动边缘计算平台上的应用实例之间的下行数据的传输路径为源移动边缘计算平台-源接入点-终端;在终端从源接入点切换到目的接入点后,终端与源接入点断开,因此下行数据就会丢失,而本公开实施例中方法在终端从源接入点切换到目的接入点后,通过将下行数据发送给目的移动边缘计算平台,以使所述目的移动边缘计算平台将所述下行数据经所述目的接入点发送给所述终端,也就是说,将上述传输路径切换为源移动边缘计算平台-目的移动边缘计算平台-目的接入点-终端,从而可以有效保持移动终端与驻留在源移动边缘宿主上的应用实例间的通信畅通,有效解决移动边缘计算中由于接入点变化带来的下行数据丢失问题,并有效保持了移动边缘计算网络中业务连续性。
在本公开实施例的另一个实施方式中,所述在终端从源接入点切换到目的接入点后,所述源移动边缘计算平台从目的移动边缘计算平台接收所述上行数据之前,还包括:
所述源移动边缘计算平台在识别出准备切换事件通知时,将路由设置信息发送给所述目的移动边缘计算平台,以使所述目的移动边缘计算平台配置与所述源移动边缘计算平台之间的第一路径;所述准备切换事件通知具体为所述终端准备从源接入点切换到目的接入点的通知;所述第一路径用于传输所述上行数据。
上述两个实施方式是基于数据面实施的,本公开实施方式中,上行数据通过控制面配置的第一路径进行传输,进一步,保持了移动边缘计算网络中业务连续性。
进一步说,所述识别出准备切换事件通知,包括:
订阅用于发布切换事件的网络信息服务;
基于所述网络信息服务,识别出所述切换准备事件通知。
在本公开实施例的另一个实施方式中,所述源移动边缘计算平台将所述下行数据发送 给所述目的移动边缘计算平台,以使所述目的移动边缘计算平台将所述下行数据经所述目的接入点发送给所述终端之前,还包括:
所述源移动边缘计算平台接收所述目的移动边缘计算平台的路径切换请求;根据所述请求配置与所述目的移动边缘计算平台之间的第二路径;所述第二路径用于传输所述下行数据。
本公开实施方式中,下行数据通过控制面配置的第一路径进行传输,进一步,保持了移动边缘计算网络中业务连续性。
以eNB(Evolved Node B,演进型基站)为例,以示例性实施方式描述本公开中方法;如图3所示:
步骤1、源MEC平台订阅RNIS(网络信息服务)服务和切换事件;源MEC平台包括源RNIS和源转发面。
步骤2、目的MEC平台订阅RNIS和切换事件。
步骤3、源eNB和源MEC平台之间交互上下行数据包;也就是说,终端切换到目的eNB之前,下行报文从源MEC平台发往源eNB;上行报文从源eNB发往源MEC平台的数据面。
步骤4、当源eNB准备切换到目的eNB时,源MEC平台的RNIS服务识别出切换准备事件(handover preparation event)。具体说,当终端接入到目的eNB后,目的eNB发起路径切换,SGW(Serving GateWay,服务网关)将路径切换到目的eNB。
步骤5、源RNIS服务将准备切换通知源MEC平台。据此,源MEC平台可以获知目的MEC平台的地址。
步骤6、源MEC平台将路由表信息(包括UE相关的路由等设置)发往目的MEC平台。这些设置包括,例如UE IP地址,上行GTPU隧道信息等。
步骤7、目的MEC平台根据源MEC平台发过来的路由规则配置自己的目的数据面的数据转发路径(即第一路径);
步骤8、目的MEC平台响应源MEC平台,以说明转发路径配置完毕。
步骤9、终端切换到目的eNB之后,目的MEC平台上的RNIS服务监测后续的切换完成事件。
步骤10、目的RNIS服务将切换完成通知目的MEC平台。此时,当SGW将路径切换到目的eNB之后,SGW在用户面数据包中向源eNB发送End Marker(结束标识),表示没有后续数据发送给源eNB。此时,源eNB与目的eNB间的转发通道将被拆除。若不通知源ME host(移动边缘宿主),源ME host将继续把下行数据包发送给源eNB,从而导致数据被源eNB丢弃。而本公开实施例中,上行和下行链路报文都通过目的eNB进行传递,从而可以有效解决该问题。具体说,执行步骤11和步骤12。
步骤11、上行报文从目的eNB发送到目的MEC平台的数据面。
步骤12、根据第7步设置的规则,目的MEC平台的数据面将上行数据转发到源MEC 平台的数据面。
步骤13、在目的RNIS发送通知到目的MEC平台,告知切换完成事件后,目的MEC平台发送路径切换请求到源MEC平台。
步骤14、源MEC平台配置源数据面的数据转发路径(即第二路径)。配置后,源数据面停止将下行报文发送到源eNB,并且开始将下行报文转发到目的MEC平台。
步骤15、源MEC平台响应目的MEC平台。
步骤16、下行报文从源MEC平台发往目的MEC平台;
步骤17、目的MEC平台将下行报文发往目的eNB。
基于第一实施例中用于源移动边缘计算平台的路径切换方法,本公开进一步提出一种用于目的移动边缘计算平台的路径切换方法。

本公开实施例中方法在终端从源接入点切换到目的接入点后,通过从目的接入点接收上行数据,并将上行数据发送给源移动边缘计算平台,从而将将上行数据的传输路径切换为终端-目的接入点-目的移动边缘计算平台-源移动边缘计算平台,从而可以有效保持移动终端与驻留在源移动边缘宿主上的应用实例间的通信畅通,有效解决移动边缘计算中由于接入点变化带来的上行数据丢失问题,并有效保持了移动边缘计算网络中业务连续性。
进一步说,本公开实施例还可以包括:
S403,在终端从源接入点切换到目的接入点后,所述目的移动边缘计算平台从所述源移动边缘计算平台接收下行数据;

进一步说,所述源移动边缘计算平台与所述目的移动边缘计算平台连接。
在本公开实施例的一个实施方式中,所述在终端从源接入点切换到目的接入点后,目的移动边缘计算平台从目的接入点接收上行数据,将所述上行数据发送给源移动边缘计算 平台之前,还包括:

本公开实施例通过控制面实现下行数据的传输路径的切换。
本公开中为了解决移动边缘计算中由于接入点变化带来的应用数据丢失问题,主要思路在于,如图5所示,通过目的MEC平台或网关实现上下行数据转发,从而避免应用数据丢失;图中带箭头实线表示UE移动过程,虚线表示数据传输路径。
具体说,考虑源、目的MEC平台之间的连接情况,如源MEC和目的MEC具有直连关系,通过目的MEC平台实现数据转发,如源MEC和目的MEC通过网关实现连接,则通过网关实现数据转发。
本公开中涉及源MEC平台和目的MEC平台的转发规则的修改和实施,以及网关转发规则的修改和实施。
进一步说,网关在切换过程中特定阶段起到中转业务数据的作用。
其中的特定阶段包括:当源MEC平台依然作为当前业务提供平台,目的MEC平台仅作为源MEC平台业务中转功能;当应用从源MEC平台切换到目的MEC平台。
基于此,本公开进一步提出一种用于源移动边缘计算平台的路径切换方法。

进一步说,所述网关连接所述源移动边缘计算平台和所述目的移动边缘计算平台。
以eNB(Evolved Node B,演进型基站)为例,以示例性实施例描述本公开中方法;如图7所示:
步骤1、源MEC平台订阅RNIS服务和切换事件;
步骤2、目的MEC平台订阅RNIS和切换事件;
步骤3、终端切换到目的eNB之前,源MEC平台和源eNB之间交互上下行报文;

步骤7、目的MEC平台发送路径切换请求给源MEC平台。
步骤8、源MEC平台根据请求,配置源数据面的转发路径(即第四路径)。
步骤9、配置后,源MEC平台响应目的MEC平台的路径切换请求。
步骤10、目的数据面将上行数据转发到在EPC的网关;
