网关设备指的是第三代合作伙伴计划 (The 3rd Generation Partnership
Project, 以下简称 3GPP)规范中定义的数据网关设备, 比如公共数据网网关 (Public Data Network GateWay, 以下简称 PGW) 、 通用分组无线服务技术 支持节点网关(Gateway General Packet Radio Service Support Node, 以下简称 GGSN ) 等, 都是 CT网络和外部公共数据网 (Public Data Network, 以下简 称 PDN) 的边界设备, 用于实现分组接入控制、 路由选择、 用户分组数据上 下文管理、 用户承载管理等, 是 CT核心网最为重要的用户面设备之一, 这 些网关设备功能强, 支持庞大的用户数量, 超大的数据流量。

目前的虚拟化网关设备采用简单的软件化方式, 将上述运行在专用硬件 上的功能一对一的映射到实现相同功能的软件程序上, 从而可以保证整体逻 辑架构不变, 保证系统架构的稳定。 但是由于各个功能间的关系与原系统一 样, 耦合性比较强, 因而难以实现更高的资源利用, 本专利将解决这个问 题。
为使本发明实施例的目的、 技术方案和优点更加清楚, 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。

图 5为本发明消息处理方法实施例一的流程图, 如图 5所示, 本实施例 的方法可以包括:
步骤 101、 网关的控制面模块生成业务控制规则, 所述业务控制规则用 于指示网关的用户面模块需要执行的数据操作;

歩骤 102、 所述控制面模块向所述用户面模块下发所述业务控制规则; 本实施例中, 控制面模块将生成的业务控制规则下发给用户面模块, 可 以是将业务控制规则下发给所有的用户面模块, 也可以是只下发给参与当前 业务的用户面模块, 例如, 在 UE接入业务中, 用户面只有 I/O子模块参与该 业务, 控制面模块可以将针对这一业务的业务控制规则只下发给 I/O 子模 块, 也可以将该业务控制规则下发给所有的用户面模块, 包括 I/O子模块、 会话处理子模块等, 这两种方式都可以用于实现本实施例的方法, 本实施例 对此不作具体限定。
歩骤 103、 所述用户面模块根据所述业务控制规则进行数据转发或者处 理。
本实施例中, 用户面模块接收到控制面模块下发的业务控制规则后, 根 据业务控制规则中的数据操作部分进行相应的操作, 例如, I/O 子模块根据 业务控制规则的指示, 将数据包转发给控制面的接入管理子模块; 会话处理 子模块根据业务控制规则的指示, 将数据包转发给其它用户面模块, 并且对 数据包进行服务质量 (Quality of Service, 以下简称 QoS ) 处理。
本实施例, 通过将网关划分为控制面模块和用户面模块, 使网关的功能 解耦合, 以控制面模块生成业务控制规则指导用户面模块的行为, 用户面模 块根据业务控制规则执行具体的数据操作的方式, 不但实现网关的基本功 能, 还可以根据需要实现更多样化的网关功能, 以解决现有的网关多个功能 紧耦合于一体, 相互制约, 不利于网关的功能扩展和性能改进的问题。
进一步的, 上述实施例的步骤 103中, 所述用户面模块根据所述业务控 制规则进行数据处理, 具体的实现方式可以是下述方法中的至少一种方法: 第一种, 所述用户面模块根据所述业务控制规则, 向其它用户面模块或所述 控制面模块转发所述业务请求消息和用户信息数据包; 第二种, 所述用户面 模块根据所述业务控制规则, 对用户设备 UE发送的数据包进行处理。
本实施例中, 网关的用户面模块根据业务控制规则中的数据操作部分, 执行具体的数据操作, 该数据操作可以是数据转发, 例如, I/O子模块将 UE 的数据包转发给控制面模块, 或者将控制面模块发送的数据包转发给会话处 理子模块, 该数据操作还可以是根据运营商的需求对数据包进行的处理, 例 如, 会话处理子模块根据控制面模块生成的业务控制规则中的承载信息, 执 行与该承载信息对应的 QoS控制操作, 用于实现压缩功能的扩展子模块对数 据包做压缩处理、 用于实现加速功能的扩展子模块对 UE的网页浏览做数据 加速操作等。 基于上述网关的结构, 本实施例可以灵活的执行多样化的网关 用户面操作, 不必受限于网关设备的结构, 使 UE业务的处理流程更加灵 活、 高效。
进一步的, 上述实施例的步骤 101 中, 网关的控制面模块生成业务控制 规则, 具体的实现方式可以是下述方法中的至少一种方法: 第一种, 所述控 制面模块根据所述网关的功能预先设置所述业务控制规则; 第二种, 所述控 制面模块根据所述业务请求消息生成所述业务控制规则。 其中, 第二种方法 是基于所述控制面模块接收所述用户面模块发送的业务请求消息后才实施 的, 进一步的, 在控制面模块接收的业务请求消息之前, 用户面模块的 I/O 子模块先接收 UE发送的业务请求消息, 并将该业务请求消息发送给所述控 制面模块。
本实施例中, 网关的控制面模块生成业务控制规则的方法可以是根据网 关的基本功能预先设置业务控制规则, 例如, 控制面模块可以根据 3GPP标 准中定义网关设备的功能以及网关设备信令消息预先设置 I/O子模块的消息 转发规则, 使得当 I/O子模块通过接口接收到其它网元发送的信令消息时, 根据预设的业务控制规则将该信令消息转发给控制面模块的会话管理子模 块; 也可以是在收到 I/O子模块发送的 UE的业务请求消息后, 针对该业务请 求消息生成业务控制规则, 例如, 控制面模块根据 I/O子模块发送的承载建 立请求生成承载建立规则, 使得会话处理子模块对数据包进行 QoS 控制, I/O 子模块对数据包进行转发。 通过上述的两种业务控制规则生成方式, 控 制面模块不但可以针对网关的基本功能生成业务控制规则, 以使用户面模块 实现该基本功能, 还可以针对 UE的业务请求生成业务控制规则, 是对网关 基本功能的扩展, 也使得网关的功能扩展和性能扩展得以灵活的实现。
图 6为本发明消息处理方法实施例二的流程图, 如图 6所示, 本实施例 的方法可以包括:
歩骤 201、 网关的用户面模块接收 UE发送的业务请求消息, 并将业务请 求消息发送给网关的控制面模块;
歩骤 202、 控制面模块接收用户面模块发送的业务请求消息; 歩骤 203、 控制面模块根据业务请求消息生成业务控制规则; 本实施例中, 控制面模块根据业务请求消息生成业务控制规则的过程与 上述方法实施例的步骤 101类似, 此处不再赘述。
步骤 204、 控制面模块向用户面模块下发业务控制规则;
本实施例中, 控制面模块向用户面模块下发业务控制规则的过程与上述 方法实施例的歩骤 102类似, 此处不再赘述。
步骤 205、 用户面模块接收控制面模块发送的业务控制规则, 并将业务 控制规则保存在本地;
本实施例中, 为了使手续的操作进行的更高效, 用户面模块在接收到控 制面发送的业务控制规则后, 将该业务控制规则保存在本地, 如果后续遇到 相同或类似的业务请求可以直接使用本地保存的业务控制规则, 省去了与控 制面模块之间的交互, 使业务流程更加简洁。
步骤 206、 用户面模块将业务请求消息的一个或多个协议头信息与本地 保存的所有业务控制规则进行匹配, 获取与业务请求消息对应的业务控制规 则;
本实施例中, 用户面模块接收到的 UE的业务请求消息中, 包括一个或 多个协议头 (Protocol Header, 以下简称 PH) , 可以用于记录 MAC层、 网 络层、 传输层、 会话层以及应用层中至少一个的特征信息, 例如该业务请求 消息的业务标识、 网关信令或者协议类型等, 用户面模块根据协议头中的信 息对本地保存的所有的业务控制规则的规则特征信息分别匹配, 如果有一个 或多个特征信息都不匹配, 则滤掉该业务控制规则, 直到匹配出与该业务请 求消息完全匹配的业务控制规则。 该业务控制规则为控制面模块针对该业务 请求生成的规则, 其中包括了用户面模块需要执行的数据操作。
步骤 207、 用户面模块根据所述业务控制规则进行数据处理。
本实施例中, 用户面模块根据所述业务控制规则进行数据处理的过程与 上述方法实施例的步骤 103类似, 此处不再赘述。
本实施例, 通过控制面模块针对 UE 的业务请求消息生成业务控制规 则, 指导用户面模块执行对应的数据操作, 使网关的业务处理流程简洁高 效。
进一歩的, 上述实施例的步骤 202之后, 还包括控制面对用户面模块进 行扩展的步骤, 具体的实现方式可以是: 控制面模块根据所述业务请求消息 和所述网关的资源信息, 在所述网关中增加至少一个用于实现所述业务请求 消息对应的至少一个功能的扩展子模块。 这种情况下, 上述实施例的步骤 203 中, 控制面模块根据业务请求消息生成业务控制规则, 具体的实现方式 可以是: 所述控制面模块生成所述业务控制规则, 所述业务控制规则用于指 示增加所述至少一个扩展子模块后所述用户面模块需要执行的数据操作。
本实施例中, 根据运营商的需求, 网关设备除了基本功能, 还需要实现 一些特殊的功能, 例如视频加速、 网页浏览加速等, 在这种情况下, 控制面 模块要根据业务请求消息, 在网关中增加至少一个扩展子模块, 这些扩展子 模块用于实现该业务请求消息中涉及的至少一个特殊功能, 例如, 视频加速 请求消息中, 涉及到视频加速功能, 但是这功能不是网关的基本功能, 用户 面模块中没有用于实现视频加速功能的子模块, 因此控制面模块在网关中增 加至少一个扩展子模块, 该扩展子模块用于实现视频加速功能, 增加的扩展 子模块的数量可以根据网关的资源情况以及业务量大小来决定, 此处不做具 体限定。 控制面模块在生成业务控制规则时, 考虑增加的扩展子模块, 可以 在业务控制规则中增加指示该扩展子模块需要执行的数据操作的内容, 同时 还要更新指示参与到该视频加速业务中的其它用户面模块需要执行的数据操 作的内容, 可以认为是在其它用户面模块的业务数据包的数据路径中增加了 扩展子模块这一路径节点。
本实施例, 通过增加用户面模块使网关实现运营商要求的特殊功能, 使 得网关的功能扩展和性能扩展得以灵活的实现。
下面采用三个具体的实施例, 对上述网关实现具体业务的流程进行详细 说明。
图 7为本发明网关业务处理实施例一的流程图, 本实施例中, 控制面模 块还负责检査用户面模块的状态, 便于及时排除网关的故障。 如图 7所示, 本实施例的方法可以包括:
5301、 资源管理子模块检査用户面模块的工作状态;
具体的, 资源管理子模块可以通过与用户面模块的连接是否正常来判断 该用户面模块状态是否正常; 还可以是向用户面模块发送查询消息, 通过查 询消息的反馈情况判断该用户面模块状态是否正常; 还可以是用户面模块向 控制面模块发送标识信息, 如果控制面模块在规定的时间内没收到该用户面 模块的标识信息, 则说明该用户面模块处于非工作状态, 需要进行故障处 理。 上述各种方式可以周期性的进行。 具体的实现方式本实施例不作具体限 定。
5302、 若检查到用户面模块处于非工作状态, 则资源管理子模块根据网 关的资源信息, 在网关中增加至少一个用于替换用户面模块的扩展子模块, 至少一个扩展子模块实现的功能与用户面模块的功能相同;
本实施例中, 若资源管理子模块检査到用户面模块处于非工作状态, 解 决的办法是另外增加至少一个扩展子模块, 用于实现出现故障的用户面模块 的功能, 并用至少一个扩展子模块替换故障用户面模块, 相当于是抛弃出现 故障的用户面模块, 用其它的模块代替该用户面模块, 可以快速排除网关的 故障。
S303、 会话管理子模块更新业务控制规则, 该业务控制规则用于指示替 换操作后所述用户面模块需要执行的数据操作;
本实施例中, 由于用户面模块发生了替换, 所以控制面模块需要更新业 务控制规则, 具体的实现方式可以是只将与故障用户面模块相关的业务控制 规则进行更新, 更新后的业务控制规则中的数据操作部分将原来的故障用户 面模块的内容更新为增加的扩展子模块的内容, 可以认为是用户面模块的业 务数据包的数据路径中的一个路径节点发生了变化。
5304、 会话管理子模块向扩展子模块、 其它相关用户面模块下发业务控 制规则;
本实施例中, 控制面模块向所述用户面模块下发所述业务控制规则的过 程与上述方法实施例的步骤 102类似, 此处不再赘述。
5305、 扩展子模块根据业务控制规则进行数据处理。
本实施例中, 用户面模块根据所述业务控制规则进行数据处理的过程与 上述方法实施例的步骤 103类似, 此处不再赘述。
本实施例中, 通过网关的控制面模块检査用户面模块的状态, 可以及时 发现网关中出现故障的用户面模块, 并对故障进行排除, 实现网关高效的故 障处理。
图 8为本发明网关业务处理实施例二的流程图, 如图 8所示, 本实施例 的方法可以包括:
分组数据协议(Packet Data Protocol, 以下简称 PDP )激活流程可以分为 两种情况, 一种是 UE初始接入时, 网关将为该 UE激活缺省的 PDP上下 文, 作为该 UE的缺省承载通道; 另一种是 UE在进行具体业务时, 网关为该 UE再次激活专有承载的 PDP上下文, 用于承载指定的业务, 一般这种情况 对专用承载会带有 QoS要求。
5401、 I/O子模块接收 UE发送的 PDP激活消息;
本实施例是一个 PDP激活的具体实施例, UE发送的 PDP激活消息可以 是 3GPP中定义的 Create PDP Context Request消息。
5402、 I/O子模块根据本地保存的业务控制规则匹配出 PDP激活消息对 应的转发规则;
本实施例中, I/O子模块根据接收到的 PDP激活消息在本地保存的多个 业务控制规则中逐一匹配, 这里的多个业务控制规则可以是控制面模块根据 网关的基本功能以及 3GPP标准中定义的网关消息预先设置的, I/O子模块将 PDP激活消息中的协议头拆分出来, 与本地保存的多个业务控制规则的一个 或多个规则特征信息进行匹配, 找出该 PDP激活消息对应的转发规则, 该转 发规则的内容可以是:
IRequest=Create PDP Context RequestlActions=Controller:Accessl 其中, Request表示该转发规则的规则特征信息, Actions 表示数据操 作。
根据该转发规则, I/O子模块获知要将 PDP激活消息转发给控制面模块 的接入管理子模块。
S403、 I/O子模块根据转发规则将该 PDP激活消息转发给接入管理子模 块;
5404、 接入管理子模块处理 UE的接入过程, 并将 PDP上下文数据发送 给会话管理子模块;
本实施例中, 接入管理子模块与用户数据网元交互, 获取用户的上下文 信息, 并结合 PDP激活消息、 用户的签约信息等, 生成 PDP上下文数据, 然 后将该 PDP上下文数据发送给控制面模块的会话管理子模块。
5405、 会话管理子模块生成 PDP激活处理规则, 并将 PDP激活处理规 则下发给 I/O子模块和会话处理子模块;
本实施例中, 会话管理子模块根据接收到的 PDP上下文数据, 以及当前 网关用户面模块的会话处理子模块的资源使用情况, 选择其中一个会话处理 子模块处理该 UE的 PDP激活流程, 并根据选择的结果生成 PDP激活处理规 贝 IJ , 然后将该 PDP激活处理规则下发给 I/O 子模块和选中的会话处理子模 块。
5406、 I/O子模块根据接收到的 PDP激活处理规则, 将该 PDP激活流程 产生的数据转发到会话处理子模块;
本实施例中, 会话管理子模块生成的 PDP激活处理规则包括指示 I/O子 模块需要执行的数据操作的内容, I/O子模块根据该 PDP激活处理规则即可 获知自身需要执行的数据操作。
5407、 会话处理子模块根据接收到的 PDP激活处理规则, 进行 QoS控制 以及数据转发。
本实施例中, 会话管理子模块生成的 PDP激活处理规则包括指示会话处 理子模块需要执行的数据操作的内容, 例如, 该 UE的承载信息、 数据路径 等, 会话处理子模块根据该 PDP激活处理规则即可获知自身需要执行的 QoS 控制的具体参数, 以及数据包的转发对象。
通过上述 PDP激活流程, 网关为 UE创建缺省或专用承载, UE即可以 在该承载上传送业务数据。 当 UE在该承载上的业务数据包到达 I/O子模块 时, I/O子模块从本地保存的多个业务控制规则中匹配到与 UE的业务请求消 息对应的业务控制规则, 并执行该业务控制规则指示的数据操作, 对业务数 据包进行转发, I/O 子模块的这个过程可以重复执行, 实现网关内部业务数 据包的转发, 最终 I/O子模块将结果数据转出网关; 对于会话子模块来讲, 同样也可以从本地保存的业务控制规则中匹配到与 UE的业务请求消息对应 的业务控制规则, 再根据该业务控制规则执行相应的数据操作。 从上述用户 面模块的数据操作过程可以看出, 控制面模块生成业务控制规则可以认为是 在用户面模块间搭建了一个处理该业务数据包的数据路径, 各用户面模块只 需要执行业务控制规则中与自身相关的数据操作即可, 该数据路径就能够自 动建立起来。
图 9为本发明网关业务处理实施例三的流程图, 如图 9所示, 本实施例 的方法可以包括:
通常情况下, 网关的用户面模块有两类基本功能模块, I/O 子模块和会 话处理子模块, 而在实际的网关设备中, 会有一些更为复杂的功能, 比如计 费、 内容识别等, 或者根据运营商的特殊需求加入的如内容压缩、 网页加 速、 视频加速等用户面功能, 在网关架构下, 基于业务控制规则建立数据路 径的方式, 具体的实现方式可以是: 本实施例以视频加速业务为例。
S501、 I/O子模块接收 UE发送的 PDP业务请求消息;
S502, I/O子模块根据本地保存的业务控制规则匹配出 PDP业务请求消 息对应的转发规则, 并将该 PDP业务请求消息转发给会话管理子模块和资源 管理子模块;
本实施例中, I/O子模块将 PDP业务请求消息与本地保存的业务控制规 则逐一匹配, 根据匹配结果获知该 PDP业务是一个视频加速业务, 需要将业 务数据包转发给控制面模块, 具体的可以是控制面模块的会话管理子模块, I/O子模块执行该转发操作。
S503、 资源管理子模块在网关中增加至少一个用于实现视频加速的扩展 子模块;
本实施例中, 控制面模块根据 PDP业务请求消息获知该 PDP业务是一个 视频加速业务, 但是当前的用户面模块中没有处理视频加速这一功能的模 块, 因此, 控制面模块结合当前资源使用情况, 在网关中增加至少一个用于 实现视频加速功能扩展子模块, 于是网关具备了视频加速的用户面功能。
5504、 会话管理子模块生成视频加速控制规则, 并将视频加速控制规则 发送给 I/O子模块、 会话处理子模块以及扩展子模块;
本实施例中, 会话管理子模块生成的视频加速控制规则包括指示增加的 扩展子模块的需要执行的数据操作的内容, 还包括指示参与到视频加速业务 中的其它用户面模块需要执行的数据操作的内容, 例如, 视频加速中有需要 由 I/O和 QoS管理, 因此至少一个 I/O子模块和至少一个会话处理子模块也 会参与到视频加速业务中, 这些用户面模块也会接收到控制面模块下发的视 频加速控制规则, 指示它们转发数据或执行 QoS管理。
5505、 I/O 子模块、 会话处理子模块以及扩展子模块根据视频加速控制 规则执行各自的数据操作。
通过上述流程, 网关可以实现运营商需要的视频加速功能, 基于类似的 流程, 网关还可以实现数据压缩、 网页加速、 基于计费的 QoS服务等多种特 殊功能, 而且这些特殊功能的实现流程简单、 高效, 可以灵活部署和实施。
