背景技术
随着虚拟化技术的发展，在业务的部署中，运营商越来越重视设备的高稳定性，多个控制面(Control Plane，CP)备份、多个转发面(User Plane，UP)备份是目前的常见方案，这些方案可以解决大部分场景下业务环境的问题。
虚拟宽带接入服务器(Virtual Broadband Remote Access Server，vBRAS)环境中，CP可以统一管理多个UP，可提供大量宽带用户的接入，易于快速扩容和增加新功能，可支持非对称数字用户环路(Asymmetric Digital Subscriber Line，ADSL)、局域网(Local Area Network，LAN)、无线接入等多种接入方式，满足各种不同类型的运营商和服务提供商的需要。具有简单、高效、统一的vBRAS模式，提供灵活的多种认证、计费和管理方法。
当极端情况出现时，CP和UP通道出现完全失联，设备无法对用户请求做出响应，会导致用户体验极差。
发明内容
本申请实施例提供了一种报文处理方法、设备及存储介质，以至少避免相关技术中，当CP和UP通道完全失联，设备无法对用户请求做出响应的情况。
根据本申请的一个实施例，提供了一种报文处理方法，应用于虚拟宽带接入服务器vBRAS，包括：转发面UP接收新用户发送的上线请求报文；响应于确 定所述UP和控制面CP之间的控制通道出现异常，且异常时间超过第一预设时间，所述UP响应所述上线请求报文，且完成所述新用户的上线操作。

可选地，在UP接收新用户发送的上线请求报文后，还包括：响应于确定在所述UP和所述CP之间的控制通道出现异常，且异常时间小于或等于第一预设时间；所述UP不响应所述上线请求报文，且不进行所述新用户的上线操作。
可选地，在所述UP响应所述上线请求报文，且完成所述新用户的上线操作后，还包括：响应于确定所述UP和所述CP之间的控制通道恢复正常，且正常时间大于第二预设时间，所述UP完成所述新用户的下线操作，并删除所述新用户的信息。
可选地，在所述UP完成所述新用户的下线操作，并删除所述新用户的信息之后，还包括：所述UP将所述上线请求报文转发至所述CP；所述CP响应于所述上线请求报文，完成通道恢复后新用户的上线操作。
根据本申请的另一个实施例，提供了一种报文处理方法，应用于虚拟宽带接入服务器vBRAS，包括：转发面UP接收在线用户发来的保活报文；响应于确定所述UP和控制面CP之间的控制通道出现异常，所述UP响应所述保活报文，且完成所述在线用户的保活操作。

附图说明
图1是根据本申请实施例的一种报文处理方法的流程图；
图2是根据本申请实施例的另一种报文处理方法的流程图。
具体实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例一
本申请实施例一所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置中执行。在本实施例中提供了一种报文处理方法，图1是根据本申请实施例的一种报文处理方法的流程图，如图1所示，该流程包括步骤S101至S102。
步骤S101，转发面UP接收新用户发送的上线请求报文。
步骤S102,在所述UP和控制面CP之间的控制通道出现异常，且异常时间超过第一预设时间的情况下，所述UP响应于所述上线请求报文，完成所述新用 户的上线操作。
当CP和UP之间的控制通道正常时，新用户发起上线请求，并通过上线请求报文的形式发送给UP，UP将所述上线请求报文通过控制通道发送给CP，CP回应用户的上线请求报文，并将回应报文通过控制通道发回给UP，UP再将所述回应报文发送给用户，至此，用户上线协商流程完毕。CP负责管理上线的用户信息，UP负责用户流量的转发。用户类型包括以太网上的点对点协议(Point-To-Point Protocol Over Ethernet，PPPOE)，以太网上的因特网协议(IP over Ethernet，IPOE)以及固定网际互连协议(Internet Protocol，IP)用户(IPHOST)等类型。
当CP和UP之间的控制通道出现故障时，UP无法将用户的上线请求报文转发给CP，用户无法完成上线操作。
在CP和UP之间的控制通道出现异常后，可以设定一个定时器，如果在T1(相当于第一预设时间)内，所述控制通道就恢复了正常，则在所述T1时间内，不对新用户发送的上线请求报文进行处理，只是先处理在线用户的业务。
如果在T1时间内，所述控制通道还未恢复正常。此时UP接管业务，将vBRAS切换为BRAS模式，其收到的新用户上线请求报文不再发给CP，直接经UP处理后发还给所述新用户。考虑到业务的方便，这段时间内容通过UP上线的用户可以不认证也不计费，尽量保证用户上网业务不间断或仅有短暂断网。
在vBRAS切换为BRAS模式后，当发现CP和UP之间的控制通道恢复正常，可以设定一个定时器，如果在T2(相当于第二预设时间)后，所述控制通道仍保持正常，所有在UP接管业务时在线的用户都会全部下线，所述通过UP上线的新用户会被强制下线，UP会删除所述新用户的信息。设备重新恢复至vBRAS模式，UP收到用户的上线请求报文并通过控制通道转发给CP，CP对所述请求报文做出回应，完成用户的上线操作；如果在T2内，所述控制通道又出现了异常，则仍由UP接管业务，保持BRAS模式。
通过上述步骤，避免了vBRAS环境中，CP和UP之间控制通道出现故障时，设备无法对用户请求做出响应的情况，提高了vBRAS模式的可靠性和灵活性。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件。基于这样的理解，本申请的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如只读存储器(Read-Only Memory，ROM)/随机存取存储器(Random Access Memory，RAM)、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例所述的方法。
实施例二
本申请实施例二所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置中执行。在本实施例中提供了另一种报文处理方法，图2是根据本申请实施例的另一种报文处理方法的流程图，如图2所示，该流程包括步骤S201至S202。
步骤S201，转发面UP接收在线用户发来的保活报文。
步骤S202，在所述UP和控制面CP之间的控制通道出现异常的情况下，所述UP响应于所述保活报文，完成所述在线用户的保活操作。
当CP和UP之间的控制通道正常时，在线用户发起保活请求，并通过保活请求报文(即步骤s201中的保活报文)的形式发送给UP，UP将所述保活请求报文通过控制通道发送给CP，CP回应用户的保活请求报文，并将回应报文通过控制通道发回给UP，UP再将所述回应报文发送给用户，至此，用户保活流程完毕。CP负责管理在线用户的用户信息，UP负责用户流量的转发。用户类型包括以太网上的点对点协议(Point-To-Point Protocol Over Ethernet，PPPOE)，以太网上的因特网协议(IP over Ethernet，IPOE)以及固定IP用户(IPHOST) 等类型。
在CP和UP之间的控制通道出现异常后，在线用户通过向UP发送保活报文或续租报文完成保活或续租操作，仍保持在线状态；如果保活或续租不成功的话，在线用户将下线，且UP主动删除其用户信息。新用户发送上线请求报文给UP，UP直接本地处理后发还给新用户，新用户完成上线。
在CP和UP之间的控制通道恢复正常后，可以设定一个定时器，如果正常时间超过了T3时间(相当于第三预设时间)，所述UP将所述通过其保活的在线用户全部下线，并删去所述在线用户的用户信息。在线用户的保活报文仍是通过UP转发给CP，由CP做出回应，并完成所述在线用户的保活。
通过上述步骤，避免了vBRAS环境中，CP和UP之间控制通道出现故障时，设备无法对用户请求做出响应的情况，提高了vBRAS模式的可靠性和灵活性。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例所述的方法。
