Description

一种网络故障的处理方法和设备 技术领域
本发明涉及通信领域, 尤其涉及一种网络故障的处理方法和设 备。
背景技术
现有的演进分组系统 ( Evolved Packet System , EP S ) 无线网络 架构主要包括:
演进的通用 陆基无线接入网 ( Evolved Universal Terrestrial Radio Access Network , EUTRAN ): 由多个演进基站(Evolved Node B, eNodeB)组成的网络, 实现无线物理层功能、 资源调度和无线资源管 理、 无线接入控制以及移动性管理功能。 eNodeB通过 S 1 用户面接 口 S 1 -U和服务网关(Serving Gateway, S-GW)相连, 用于传送用户数 据; 通过 S 1 控制面接口 S 1 -MME 和移动性管理实体 (Mobility Management Entity, MME)相连, 釆用 S 1应用协议 S 1 -AP协议实现 无线接入承载控制等功能。
MME : 主要负责用户即会话管理的所有控制平面功能, 包括非 接入层(Non-Access Stratum)NAS信令及安全, 跟踪区列表(Tracking Area List)的管理, 分组数据网 络网 关 ( Packet Data Network Gateway , P-GW ) 与 S-GW的选择等。
S-GW : 主要负责用户设备的数据传输、 转发以及路由切换等, 并作为用户设备在 eNodeB 之间切换时的本地移动性锚定点 (对于 每一个用户设备, 每个时刻仅有一个 S-GW为之服务)。
P-GW : 作为分组数据网络 ( Packet Data Network , PDN ) 连接 的锚定点, 负责用户设备的互联网协议 ( Internet Protocol , IP ) 地 址分配, 用户设备的数据报文过滤、 速率控制、 生成计费信息等。
用户设备(User Equipment , UE)通过附着流程, 接入 EP S 网络 并创建 PDN连接, 在此过程中, P-GW为用户设备分配 IP地址, 用 户设备通过该 IP地址连接实现与外部网络的数据传输。 如果长时间 没有数据传输, 用户设备会进入空闲态 ( Idle ) , 此时, eNodeB上的 用户上下文会被删除, MME 无法精确的知道用户设备处于哪个 eNodeB下。 当 EPS 网络收到了用户下行的数据报文时, 网络侧必须 首先寻呼用户设备, 当用户设备转入连接态 ( Connected ) 后, 将用 户的下行数据发送给用户设备。
为了降低用户设备的电量消耗, 现有技术使用了电量节约模式 ( Power Saving Mode ) 与非连续接收模式 (Discontinuous Reception , DRX)。 电量节约模式是指用户设备进入准关机状态, 在这种状态下 用户设备无法响应网络侧的寻呼; 而非连续接收模式是指用户设备 与网络侧协商使用较长的 DRX周期值, 以实现用户设备的节电。
在现有技术中, 当用户设备进入电量节约模式时, 是无法响应 寻呼的; 而用户设备进入非连续接收模式时, MME必须有用户设备 的非连续接收周期值才能正确的寻呼用户设备。 但是由于 MME 故 障, 会导致用户设备当前的状态信息丟失, 因此收到下行数据通知 信息的 MME (重启后的 MME或者其他的 MME)无法正确的寻呼用户 设备, 从而导致网络资源的不必要的消耗, 甚至无法实现服务的恢 复。

404、 eNodeB根据收到的寻呼信息对用户设备进行寻呼。
405、 用户设备响应寻呼, 发起服务请求流程, 重新附着至 EPS 网络, 建立起用户面, 开始准备接收下行数据报文。
月良务恢复机制的流程为: 当 S -G W检测到 MME发生故障后, S-GW继续保留用户设备的上下文信息,当收到用户设备的下行数据 才艮文后, S-GW发送下行数据通知信息给任意的 MME (;重启后的 MME 或者其他 MME , 在图 4所示的网络触发服务请求流程中, S-GW发 送下行数据通知信息给存储有用户设备上下文信息的 MME) , 然后 执行网络触发服务请求流程的步骤 402、 403、 404、 405 , 从而实现 了服务的恢复。
需要说明的是, 服务恢复机制的流程与网络触发服务请求流程 区别在于步骤 401。
本发明的实施例提供一种网络故障的处理设备, 获取用户设备 的省电状态; 若检测到管理用户设备的移动性管理实体 MME故障, 则根据省电状态为用户设备选择服务恢复策略, 服务恢复策略包括: 不发起服务恢复或发起服务恢复。 能够在 MME 故障后根据用户设 备的节电状态决定服务恢复策略, 可以减少网络资源不必要的消耗。
本发明的实施例提供一种网络故障的处理方法, 如图 5所示, 该方法包括:
501、 获取用户设备的省电状态。 其中, 用户设备的省电状态包括:
用户设备激活电量节约模式; 或, 用户设备激活非连续接收模 式且非连续接收周期值未知; 或, 用户设备激活非连续接收模式且 非连续接收周期值已知。
502、 若检测到管理用户设备的移动性管理实体 MME故障, 则 根据省电状态为用户设备选择服务恢复策略, 服务恢复策略包括: 不发起服务恢复或发起服务恢复。
本发明的实施例提供一种网络故障的处理方法, 获取用户设备 的省电状态; 若检测到管理用户设备的移动性管理实体 MME故障, 则根据省电状态为用户设备选择服务恢复策略, 服务恢复策略包括: 不发起服务恢复或发起服务恢复。 能够在 MME 故障后根据用户设 备的节电状态决定服务恢复策略, 可以减少网络资源不必要的消耗。
为了使本领域技术人员能够更清楚地理解本发明实施例提供的 技术方案, 下面通过具体的实施例, 对本发明的实施例提供的网络 故障的处理方法进行详细说明, 如图 6所示, 该方法包括:
601、 获取用户设备的省电状态。
其中, 用户设备的省电状态包括:
用户设备激活电量节约模式; 或, 用户设备激活非连续接收模 式且非连续接收周期值未知; 或, 用户设备激活非连续接收模式且 非连续接收周期值已知。
具体的, 可以在用户设备的附着流程中获取用户设备的省电状 态: 在附着流程中, MME接收到用户设备发送的包含省电状态的附 着请求信息; MME下发包含省电状态的指示信息, 指示信息包括: 创建会话请求信息、 修改承载请求信息中的至少一种; 接收指示信 息则获取省电状态。
示例性的, 以图 2为例进行说明, 用户设备可以在步骤 201 中 向 eNodeB 发送的附着请求信息中携带省电状态, 然后在步骤 202 中 eNodeB 将携带该省电状态的附着请求信息转发给 MME , MME 收到后, 可以在向 S-GW发送的创建会话请求信息中携带该省电状 态 (步骤 204 ) , 则 S-GW获取到用户设备的省电状态; 或者, 也可 以在向 S-GW 发送的修改承载请求信息中携带该省电状态 (步骤 214 ) , 则 S-GW获取到用户设备的省电状态。
具体的, 还可以在用户设备的路由区域更新流程中获取用户设 备的省电状态: 在路由更新流程中, MME接收到用户设备发送的包 含省电状态的路由更新请求信息; MME下发包含省电状态的指示信 息, 指示信息包括: 创建会话请求信息、 修改承载请求信息中的至 少一种; 接收指示信息则获取省电状态。
示例性的, 以图 3为例进行说明, 用户设备可以在步骤 301 中 向 eNodeB 发送的路由更新请求信息中携带省电状态, 然后在步骤 302中 eNodeB将携带该省电状态的路由更新请求信息转发给 Target MME , Target MME收到后, 在向 S-GW发送的修改承载请求信息中 携带该省电状态(步骤 305 ) , 则 S-GW获取到用户设备的省电状态。
602、 若检测到管理用户设备的 MME故障, 则根据用户设备的 省电状态为用户设备选择服务恢复策略。
具体的, 服务恢复策略包括: 不发起服务恢复或发起服务恢复。 不发起服务恢复是指 S-GW删除用户设备的上下文信息, 不向 MME 发送下行数据通知信息, 则 MME 不寻呼用户设备, 不对用户设备 进行服务恢复。 发起服务恢复是指 S-GW发送下行数据通知信息给 MME , MME寻呼用户设备完成服务恢复。
需要说明的是, 用户设备激活电量节约模式后无法响应网络侧 的寻呼; 用户设备未激活电量节约模式且未激活非连续接收模式也 即用户设备处于正常模式可以随时响应网络侧的寻呼; 用户设备激 活非连续接收模式且非连续接收周期值未知即用户激活非连续接收 模式但网络侧没有获取到用户设备的非连续接收周期值, 这种情况 下用户设备也无法响应网络侧的寻呼; 用户设备激活非连续接收模 式且非连续接收周期值已知即用户激活非连续接收模式且网络侧获 取到用户设备的非连续接收周期值, 这种情况下网络侧根据该非连 续接收周期值可以正确寻呼到用户设备。 603、若用户设备的省电状态为用户设备激活非连续接收模式且 非连续接收周期值已知, 则对用户设备发起服务恢复, 以使 MME 根据非连续接收周期值寻呼用户设备。
示例性的, 当 S-GW检测到管理该用户设备的 MME发生故障 后, 该用户设备的省电状态为用户设备激活非连续接收模式且非连 续接收周期值已知, 这种情况时, S-GW向重启后的 MME或者其他 MME发送下行数据通知信息, 按照步骤 203 中提到的服务恢复机制 的流程对用户设备进行服务恢复。
604、若用户设备的省电状态为用户设备激活电量节约模式,或, 用户设备激活非连续接收模式且非连续接收周期值未知, 则对用户 设备不发起服务恢复。
示例性的, 当 S-GW检测到管理该用户设备的 MME发生故障 后, 且该用户设备的省电状态为用户设备激活电量节约模式, 或, 用户设备激活非连续接收模式且非连续接收周期值未知, 这种情况 时, S-GW删除用户设备的上下文信息, 不向重启后的 MME或者其 他 MME发送下行数据通知信息, 这样就避免了 MME盲目寻呼用户 设备造成网络资源的浪费。
605、若用户设备的省电状态为用户设备激活电量节约模式,或, 用户设备激活非连续接收模式且非连续接收周期值未知, 则对故障 的 MME 管理的与用户设备省电状态相同的除用户设备以外的其他 用户设备也不发起服务恢复。
示例性的, 当 S-GW检测到管理该用户设备的 MME发生故障 后, 且该用户设备的省电状态为用户设备激活电量节约模式, 或, 用户设备激活非连续接收模式且非连续接收周期值未知, 这种情况 时, 故障的 MME 管理的与该用户设备的省电状态相同的除该用户 设备以外的用户设备也是无法被网络侧寻呼到, 因此, S-GW也删除 这些用户设备的上下文信息, 不向重启后的 MME或者其他 MME发 送下行数据通知信息, 这样就避免了 MME 盲目寻呼用户设备造成 网络资源的浪费。 本发明的实施例提供一种网络故障的处理方法, 获取用户设备 的省电状态; 若检测到管理用户设备的移动性管理实体 MME故障, 则根据省电状态为用户设备选择服务恢复策略, 服务恢复策略包括: 不发起服务恢复或发起服务恢复。 能够在 MME 故障后, 避免对激 活电量节约模式的用户设备的不必要的寻呼, 可以对激活非连续接 收模式且已知非连续接收周期值的用户设备正确寻呼以便恢复服 务。
