演进分组网络的核心网主要包含 MME ( Mobility Management Entity, 移动管理实体) , S-GW ( Serving Gateway, 服务网关) , P-GW ( Packet Data Network Gateway, 分组数据网络网关) 三个逻辑功能体。 MME负责 NAS ( Network Attached Storage, 网络附属存储 )信令和 NAS 信令加密以及漫游、 跟踪等功能, 分配用户临时身份标识、 安全功能等, 它对应于当前 UMTS ( Universal Mobile Telecommunications System, 通 用移动通信系统 ) 系统内部 SGSN ( Serving GPRS Support Node, 服务通 用分组无线服务技术支持节点)的控制平面部分。 S-GW负责本地的移动 性错点和 3GPP ( The 3rd Generation Partnership Project, 3G技术规范机 构)系统内部的移动性锚点以及合法监听相关信息。 P-GW负责策略执行 和计费以及合法监听相关功能。
PDN ( Packet Data Network, 分组数据网络 )连接是具有相同接入点 名称的一个承载或多个承载集合。 PDN连接建立过程中第一个创建的承 载称之为缺省承载。 若缺省承载被删除, 则视为 PDN连接被删除。
CSID ( Connection Set Identifier ) : 一个节点内一组 PDN连接的标 示。 一组 PDN连接 / PDP连接可以属于不同的用户设备。
FQ-CSID ( Fully Qualified Connection Set Identifier ) : CSID的全局 标识, 是分配 CSID的节点标识和 CSID的组合。 不同节点内部可以分配 相同的 CSID, FQ-CSID可以区别不同节点分配的相同 CSID。
当网络设备(MME或 SGSN )故障发生时, 网络设备通过删除连接 请求消息将发生故障的网络设备的 FQ-CSID发送给 S-GW; S-GW转发 收到的删除连接请求消息给 P-GW,其中包含网络设备的 FQ-CSID; P-GW 收到删除连接请求消息后将基于接收到的网络设备的 FQ-CSID检索 PDN 连接上下文确认受影响的 PDN连接并将其从本地删除, 之后向 S-GW返 回删除连接响应消息; S-GW基于收到的网络设备的 FQ-CSID检索 PDN 连接上下文确认受影响的 PDN连接并将其从本地删除, 接收到 P-GW发 送的删除连接响应消息之后向网络设备返回删除连接响应消息。
在实现上述处理设备设备故障的过程中,发明人发现现有技术中至少 存在如下问题: 网络设备、 S-GW 和 P-GW 将同步本地删除网络设备的 FQ-CSID所对应的 PDN连接, 但用户此时并不知道 PDN连接已被删除。 在从 PDN连接被删除到用户与网络主动联系的这段时间内,用户设备的所 有与被删除 PDN连接相关的业务将被叫不可达,严重影响了用户的业务体 验。

具体实施方式
下面将结合本发明实施例中的附图, 对本发明实施例中的技术 方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明 一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本 领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他 实施例, 都属于本发明保护的范围。 实施例一 本发明实施例提供了一种处理设备故障的方法, 如图 1所示, 包括:
101、 网络设备、 服务网关 S-GW和分组数据网络网关 P-GW本地删 除设备故障相关的 PDN连接。
需要说明的是, 本发明所有实施例中的网络设备为 MME ( Mobility Management Entity,移动管理实体)或 SGSN( Serving GPRS Support Node, 服务 GPRS支持节点 ) 。
102、 S-GW判定用户设备 UE的 PDN连接是被网络设备全部本地删 除还是部分本地删除。 若所有 PDN连接被网络设备本地删除则执行步骤 103a〜105a , 若部分 PDN 连接被网络设备本地删除, 则执行步骤 103b〜105b。
103a, S-GW 向网络设备发送第一消息, 该第一消息用于通知所述 网络设备触发 UE发起附着流程; 网络设备接收第一消息。 具体的, S-GW确定 UE的所有 PDN连接被网络设备删除后, 向网 络设备发送第一消息通知网络设备触发 UE发起附着流程; 优选的, 第一 消息中携带有第一标识,进一步优选的,第一标识为是 IMSI( International Mobile Subscriber Identification Number, 国际移动用户识别码 ) 。
104a, 网络设备触发 UE发起附着流程。
具体的,网络设备向 UE发送寻呼消息用于触发 UE发起附着流程以 重建所有 PDN连接 (被网络侧删除的与设备故障相关的 PDN连接) ; 寻呼消息中携带第一标识, 其中, 携带有第一标识的寻呼消息用于指示 UE发起附着流程, 优选的, 第一标识为 IMSI。
105a, UE发起附着流程。 具体的, UE接收到网络设备发送的寻呼消息后, 并检测到消息中携 带有第一标识, UE便发起附着流程以重建 UE的所有 PDN连接。
103b , S-GW 向网络设备发送第三消息, 该第三消息用于触发网络 设备执行网络侧触发的服务请求流程; 网络设备接收第三消息。 具体的, 在 S-GW确定 UE处于空闲态的情况下, S-GW向网络设备 发送第三消息用于触发网络设备执行网络侧触发的服务请求流程。 若 UE 处于连接态, 第三消息中携带有指示信息, 用于指示网络设 备将 UE从连接态迁移到空闲态。 需要说明的是, 在本发明所有实施例中, 对于 S-GW而言, 若其保 存的 UE上下文中没有可用的下行用户面信息, 则 S-GW可以确认 UE处 于空闲态, 第三消息中就不要携带上述指示信息, 此时第三消息只是用 于触发网络设备执行网络侧触发的服务请求流程。
104b, 网络设备执行网络侧触发的服务请求流程。
具体的, 网络设备接收到第三消息后, 若 UE 处于空闲态, 则网络 设备向 UE发送寻呼消息, 在寻呼消息中添加有第二标识, 其中, 携带有 第二标识的寻呼消息用于指示 UE执行服务请求流程, 优选的, 第二标识 为 S-TMSI ( Serving Temporary Mobile Subscriber Identity, 服务临时移动 用户身份标识) 。
若网络设备自身有检测 UE 所处状态 (包括: 连接态和空闲态) 的 能力, 则当网络设备检测出 UE处于连接态时, 网络设备将 UE从连接态 迁移到空闲态。 或者, 无论网络设备自身有无检测 UE所处状态的能力, 网络设备都可以根据其接收到的由 S-GW发送的第三消息获知 UE所处状 态; 具体的, 网络设备接收由 S-GW发送的携带指示信息的第三消息, 所述指示信息用于指示网络设备将 UE从连接态迁移到空闲态; 此时, 网 络设备将 UE从连接态迁移到空闲态。
其中, 若网络设备是 MME , UE处于连接态时 , MME与基站间的 连接为 S 1连接, 此时, MME可通过译放 S 1连接将 UE从连接态迁移到 空闲态; 若网络设备是 SGSN, UE处于连接态时, SGSN与无线网络控 制器间的连接是 Iu连接, 此时, SGSN可通过译放 Iu连接将 UE从连接 态迁移到空闲态。
下面以 MME执行译放 S 1连接为例进行说明。
MME向基站发送 S1 连接释放请求消息请求释放 S 1 连接, 基站接 收到请求消息后, 释放 S 1连接并向 MME返回 S1连接译放确认消息用 于通知 MME的 S 1连接译放完毕。 当 MME的 S1连接译放后, MME将 UE从连接态迁移到空闲态。 105b, UE执行服务请求流程并重建部分 PDN连接。
具体的, UE在接收到携带有第二标识的寻呼消息后, UE向网络设 备发起服务请求流程, 在服务请求流程中, UE与网络设备先进行承载同 步, 确定被网络设备删除的部分 PDN连接, 然后, UE本地相应删除部 分 PDN连接。 UE删除部分 PDN连接后, UE重新发起 PDN连接建立流 程, 重建部分 PDN连接。
下面以 MME与 UE进行承载同步为例 ,进行说明 UE如何确定被网 络设备删除的部分 PDN连接。
MME接收 UE发送的服务请求消息 , MME根据自己保存的 U E承 载信息触发恢复对应的无线承载。 由于设备故障导致 M M E删除了与设 备故障相关的部分 PDN连接, 则部分 PDN连接 (被网络侧删除的与设 备故障相关的 PDN连接) 对应的无线承载是无法被恢复的。 所以, 在服 务请求流程中, 若 U E保存的 PDN连接承载对应的无线承载未被恢复, 则 U E可以确定该 PDN连接已被网络侧删除, U E也会本地删除未恢复 的 PDN连接。 需要说明的是, 在发明实施例中需要 UE重建的部分 PDN连接就是 与设备故障相关的 UE的部分 PDN连接。 本发明实施例提供了一种处理设备故障的方法, 在网络设备发生设 备故障之后, 服务网关 S-GW接收到删除连接请求消息后, 消息中携带 有 FQ-CSID, 服务网关 S-GW本地删除与 FQ-CSID相关的 PDN连接, 通过 S-GW向网络设备发送第一消息或第三消息, 通知网络设备触发 UE 发起附着流程或网络侧发起的服务请求流程;网络设备触发 UE发起附着 流程, 使 UE重建 UE的所有 PDN连接; 或者执行网络侧发起的服务请 求流程, 触发 UE重建与设备故障相关的 UE 的部分 PDN连接, 这样能 够在设备故障发生后能及时修复与设备故障相关的 PDN连接, 提高用户 的业务体验。
实施例二 本发明实施例提供了一种处理设备故障的方法, 如图 2所示, 包括:
201、 网络设备本地删除设备故障相关的 PDN连接,服务网关 S-GW 和分组数据网络网关 P-GW暂时保留与设备故障相关的 PDN连接。 具体的, 网络设备将设备故障中相关的 PDN 连接全部本地删除, S-GW和 P-GW暂时保留与设备故障相关的 PDN连接, 并且使用特殊标 识标记与设备故障相关的 PDN连接。 优选的, 用定时器作为特殊标识标 记所有与设备故障相关的 PDN连接, 若定时器超时, 则 S-GW和 P-GW 本地删除与设备故障相关的 PDN连接。
202、 S-GW接收 PDN连接对应的下行数据。
203、 S-GW判定用户设备 UE的所有 PDN连接被网络设备本地删除 还是部分 PDN连接被网络设备本地删除。 若所有 PDN连接被网络设备 本地删除则执行步骤 204a〜206a,若部分 PDN连接被网络设备本地删除, 则执行步骤 204b〜206b。
