Description

一种控制和转发解耦下协议处理方法及控制面设备、转发面设备
【技术领域】
本发明涉及移动网络通信技术领域,特别是涉及一种控制和转发解耦下协议的处理方法及控制面设备、转发面设备。
【背景技术】
请参阅图1,图1是现有技术中一种演进网络架构的结构示意图,所述演进网络架构包括:UE(用户设备)、GERAN(全球移动通信网/全球移动通信网演进增强数据速率)、UTRAN(通用陆地无线接入网)、SGSN(服务通用分组无线服务支持节点)、MME(移动性管理实体)、HSS(归属用户服务器)、S-GW(服务网关)、P-SW(分组数据网络网关)、PDN(分组数据网络)。
UE可以通过无线空口接入E-UTRAN后,附着到MME上,MME从HSS服务器获取用户的签约数据和鉴权信息,完成对UE进行鉴权。鉴权完成后,可由用户设备或者MME发起建立用于传输用户数据的承载的过程。在该过程中,MME通知S-GW为用户建立承载,在通知消息中携带P-GW的地址和用户所在的E-UTRAN网元的地址信息。S-GW为用户建立从E-UTRAN到P-GW的用于传输用户数据的承载。P-GW将来自外部PDN的下行数据通过承载转发给UE,并将来自UE的上行数据转发给相应的PDN。
同样,UE也可以通过UTRAN/GERAN和SGSN接入到移动网络,并且可以通过UTRAN/GERAN和SGSN建立和S-GW之间的GTP隧道。UTRAN也可以通过Direct Tunnel方式建立直接连接S-GW的GTP隧道。
在演进网络架构中,MME只需要处理控制面信令,S-GW和P-GW主要负责转发用户面数据。S-GW和P-GW可以合并为一个网元,一般统称为网关。网关仍然需要保留有大量的对外的信令接口,大量对外的信令接口会带来大量的接口信令,采用专用硬件平台的网关信令处理性能不强,容易成为瓶颈。网关为了能处理大量的接口信令,势必要专用硬件平台的基础上增加大量的通用计算处理器芯片等硬件,使得网关设备的硬件平台非常复杂,成本过高,不利于移动分组数据网络的推广和部署。

下面结合附图和实施方式对本发明进行详细说明。
为让读者能更好地了解本发明实施方式的内容,以下对在网关的控制和转发解耦下的移动网络结构进行简要说明。请参阅图2,图2是本发明一种控制和转发解耦下的移动网络结构示意图。如图所示,所述移动网络10包括RAN(无线接入网)11、SGSN(服务通用分组无线服务支持节点)12以及网关13。网关13分为控制面设备131和转发面设备132,其中控制面设备131用于处理对外的信令交互,转发面设备132用于转发数据报文。用户设备15通过RAN附着于SGSN,从而使得用户设备15附着于移动网络10。当用户设备15需要使用高层业务时,则可向SGSN,进而向网关13发起请求,建立起用户设备15与网关13或LNS(层二隧道协议网络服务器)14间的业务连接。同样的,SAE(System Architecture Evolution,系统架构演进)架构中的网关也可分为控制面设备和转发面设备,并且控制面设备负责对外的信令交互,转发面负责转发数据报文。
请参阅图3,图3是本发明控制和转发解耦下协议的处理方法第一实施方式的流程图。如图所示,所述方法包括:
步骤101:使控制面设备根据分组业务处理协议的处理方式指示转发面设备并将分组业务处理协议协商参数向转发面设备下发;
分组业务处理协议是一种数据传输规则,主要用于在两个或者两个以上的网络或终端设备间建立起数据传输通道,使得网络或终端设备间能相互传输数据。分组业务处理协议包括PPP(Point-to-Point Protocol,点对点协议)、L2TP(Layer Two Tunnelling Protocol,层二隧道协议)、GRE(Generic Routing Encapsulation,通用路由封装)等。网络或终端设备间要建立起分组业务处理协议数据通道时,网络或终端设备间需要根据分组业务处理协议协商参数进行协商,使得网络或终端设备间都能确定对方在发送数据时,如何封装数据,或者在接收数据时,如何解封数据包取得数据,网络或终端设备间方能传输数据,或者说,网络或终端设备间才能建立起数据通道。
步骤102:控制面设备接收到来自转发面设备上传的根据分组业务处理协议协商参数在内的信息而得到的分组业务处理协议协商结果,建立起用户设备与网络设备之间的数据通道。
在网关的控制和转发解耦的情况下,控制面设备负责处理对外的信令交互,转发面设备负责转发数据报文,因此,转发面设备完成协商后,需要把协商结果上报至控制面设备,由控制面设备进行管理。
本发明实施方式中,控制面设备将分组业务处理协议协商参数下发至转发面设备,并根据分组业务处理协议的处理方式指示转发面设备,由转发面设备根据分组业务处理协议协商参数完成协商,控制面设备接收到转发面设备完成协商后上报的协商结果,建立起用户设备与网络设备间的数据通道。通过上述方式,使得在网关的控制和转发解耦的情况下,控制面设备和转发面设备可以配合完成分组业务处理协议协商。

其中,分组业务处理协议是一种数据传输规则,主要用于在网络或终端设备间建立起数据通道,使得网络或终端设备间能相互传输数据。网络或终端设备间要建立起分组业务处理协议数据通道,则网络或终端设备间需要根据分组业务处理协议协商参数进行协商,使网络或终端设备间都能确定对方如何处理数据。
步骤S104:控制面设备接收到来自转发面设备上传的根据分组业务处理协议协商参数在内的信息而得到的分组业务处理协议协商结果,建立起用户设备与网络设备之间的数据通道;
在网关的控制和转发解耦的情况下,控制面设备负责处理对外的信令交互,转发面设备负责转发数据报文,因此,转发面设备完成协商后,需要把协商结果上报至控制面设备,由控制面设备进行管理。

步骤S106:使控制面设备接收到的来自转发面设备上传的数据通道释放信息,并发起PDP Context释放流程;
数据通道因出现意外故障,例如:用户设备重启等,使数据通道出现异常。出现异常的数据通道不能传输数据,也不能修复。对于异常的数据通道,数据通道两端的网络或终端设备需要释放数据通道,以回收资源。在本发明实施方式中,转发面设备可以通过检测数据通道中的心跳异常,例如:PPP心跳异常、L2TP心跳异常等,即能检测到数据通道中的链路故障,并把链路故障作为数据通道释放信息上报至控制面设备。同样的,当数据通道使用完成,也需要把数据通道释放,以回收资源。其中,用户设备或LNS服务器都可以发起终结数据通道的流程,例如:用户设备发起的LCP终结流程、LNS服务器发起的L2TP会话终结流程、LNS服务器发起的L2TP隧道终结流程等,转发面设备将接收到的终结的信息作为数据通道释放信息上报至控制面设备,由控制面设备发起PDP Context释放流程,以回收资源。
