实施例或现有技术描述中所需要使用的附图作一简单地介绍， 显而易见 地， 下面描述中的附图是本发明的一些实施例， 对于本领域普通技术人员 来讲， 在不付出创造性劳动性的前提下， 还可以根据这些附图获得其他的 附图。

图 2为本发明数据分流方法的实施例的流程示意图二；
图 3为本发明数据分流方法的实施例的流程示意图三；
图 4为本发明数据发送装置的实施例的结构示意图；
图 5为本发明用户设备装置的实施例的结构示意图；
图 6为本发明分流节点装置的实施例的结构示意图。 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 有做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。
本发明实施例提供一种数据分流方法， 图 1为本发明数据分流方法的 实施例的流程示意图一， 如图 1所示， 该方法包括以下步骤：
步骤 101 : 获取分流节点装置中緩存的待发送分流数据包数量。
理论上说， 在相同时间内基站等数据发送装置发送给分流节点装置的 分流数据包数量与用户设备从分流节点装置接收的分流数据包数量应该 是相同的， 即基站到分流节点装置的传输速率与分流节点装置到用户设备 的传输速率应该是相同的， 但是， 在实际的传输过程中， 分流节点装置接 收的分流数据包会首先暂存在分流节点装置上的 buffer中， 然后从 buffer 中取出数据包信息并发送给用户设备， 在这个緩存的过程中， 如果分流节 点装置中緩存的待发送分流数据包数量过大或者过小， 都会影响分流节点 装置到用户设备的传输速率， 因此， 必须首先获取分流节点装置中緩存的 待发送分流数据包数量， 根据分流节点装置中緩存的待发送分流数据包数 量确定数据发送装置是否继续要向分流节点装置发送数据包信息。
本发明实施例主要通过数据发送装置估计分流节点装置上分流 buffer 中数据量大小来确定传输速率， 因为分流节点装置到目标 UE的链路的拥 塞或者空闲体现在分流节点装置的 buffer中等待分流的数据量大小。
步骤 102: 判断所述待发送分流数据包数量是否小于第一阈值， 若小 于所述第一阈值， 则向所述分流节点装置发送分流数据。
如果分流节点装置中待发送分流数据包数量小于所述第一阈值时， 说 明分流节点装置 buffer中等待分流的数据量较小 , 分流节点装置的存储资 源具有较大的闲置空间， 那么数据发送装置就继续给分流节点装置分流数 据包信息， 以使分流节点装置的緩存资源能够被有效的利用， 从另一方面 来说， 也提高了分流节点装置到用户设备的传输速率。 反之， 当分流节点 装置中待发送分流数据包数量大于或等于所述第一阈值时， 说明分流节点 装置 buffer中等待分流的数据量太大， 会产生延时或者丟包的现象， 从另 一方面来说会降低分流节点装置到用户设备的传输速率， 此时， 数据发送 装置就不再向此分流节点装置继续发送数据了。 本发明实施例提供了包括至少两种获取所述分流节点装置中緩存的 待发送分流数据包数量的方法， 其中一种方法具体为：
数据发送装置接收用户设备发送的分流数据包报告信息， 然后根据已 分流给所述分流节点装置的数据包信息， 以及所述用户设备从所述分流节 点装置接收到数据包信息来获取分流节点装置中緩存的待发送分流数据 包数量， 其中， 所述分流数据包报告信息包括分流节点标识， 以及用户设 备从所述分流节点装置接收到数据包的标识列表或从所述分流节点装置 接收到的最后一个数据包的标识。
具体地， 数据发送装置根据发送给分流节点装置的数据包数量和从用 户设备接收到的分流数据包报告信息便可估计出分流节点装置中緩存的 待发送数据包数量了， 其中分流数据包报告信息包括分流节点标识， 以及 用户设备从所述分流节点装置接收到数据包的标识列表或从所述分流节 点装置接收到的最后一个数据包的标识。 其中， 分流节点标识可以是分流 节点装置的 MAC地址、 IP地址或者其他标识。 数据包的标识列表可以是 TCP, IP层序列号或者其他标识。
进一步地， 在接收用户设备发送的分流数据包报告信息之前， 向用户 设备发送第一汇报指示消息， 所述第一汇报指示消息用于指示用户设备根 据预设周期发送分流数据包报告信息， 或用于指示用户设备每接收到预设 数目的数据包时发送分流数据包报告信息。
具体地， 在用户设备向数据发送装置发送分流数据包报告信息之前， 数据发送装置先向用户发送第一汇报指示消息， 所述第一汇报指示消息用 于指示用户设备以 T 为周期向数据发送装置反馈其从当前分流节点装置 接收的数据包信息； 或者所述第一汇报指示消息还可用于指示用户设备当 其从分流节点装置接收到的数据包信息数量超过某个预设值时， 用户设备 向数据发送装置反馈其接收的分流数据包信息。
进一步， 所述分流数据包报告信息中还包括有用户设备从所述分流节 点装置接收分流数据包的历史速率。
具体地， 在数据发送装置接收用户设备发送的分流数据包报告信息中 除了包括分流节点标识， 以及用户设备从所述分流节点装置接收到数据包 的标识列表或从所述分流节点装置接收到的最后一个数据包的标识以外， 还包括历史速率， 所述历史速率可根据用户设备在单位时间内从分流节点 装置接收的数据量得到。
本发明实施例提供的分流节点装置接收分流数据包的历史速率用于 给数据发送装置提供一个参考， 数据发送装置根据该历史速率的大小可估 计是否需要向分流节点装置继续分流数据。
本发明实施例还提供了另外一种获取所述获取分流节点装置中緩存 的待发送分流数据包数量的方法， 该方法具体为：
接收分流节点装置发送的緩存状态报告信息， 所述緩存状态报告信息 中包括分流节点装置中緩存的待发送分流数据包数量。
具体地， 数据发送装置接收分流节点装置发送的緩存状态报告信息， 该緩存状态报告信息包括分流节点装置中緩存的待发送分流数据包数量， 由此， 发数据送装置便可直接获取分流节点装置中緩存的待发送分流数据 包数量了， 从而， 数据发送装置可根据接收的緩存状态报告信息决定是否 需要继续向分流几点发送数据了。
进一步地， 在数据发送装置接收分流节点装置发送的緩存状态报告信 息之前， 数据发送装置还向分流节点装置发送第二汇报指示消息， 所述第 二汇报指示消息用于指示分流节点装置根据预设周期发送緩存状态报告 信息， 或用于指示分流节点装置每发送预设数目的数据包时发送緩存状态 报告信息。
具体地， 数据发送装置先向分流节点装置发送第二汇报指示消息， 分 流节点装置根据接收的第二汇报指示消息再向数据发送装置发送緩存状 态报告信息。 其中， 第二汇报指示消息用于指示分流节点装置以 T为周期 向数据发送緩存状态报告信息， 该緩存状态报告信息显示当前分流节点装 置发送给用户设备的分流数据包数量； 或者第二汇报指示消息还可用于指 示分流节点装置每发送预设数目的数据包时发送緩存状态报告信息， 具体 地说， 数据发送装置指示分流节点装置当分流节点装置中緩存的待发送的 数据包数量小于某个预设值时， 数据发送装置就继续向分流节点装置分 流， 即继续发送数据包给分流节点装置， 当分流节点装置中緩存的待发送 的数据包数量大于某个预设值时， 数据发送装置就停止向分流节点装置分 流， 即停止发送数据包给分流节点装置。 进一步， 数据发送装置接收分流节点装置发送的緩存状态报告信息中 还包括有分流节点装置发送分流数据包的历史速率、 单个用户设备在分流 节点装置中緩存的待发送分流数据包数量， 分流节点装置为单个用户设备 发送分流数据包的历史速率。
具体地， 数据发送装置接收分流节点装置发送的緩存状态报告信息中 除了包括分流节点装置中緩存的待发送分流数据包数量外， 还包括分流节 点装置发送分流数据包的历史速率、 单个用户设备在分流节点装置中緩存 的待发送分流数据包数量， 分流节点装置为单个用户设备发送分流数据包 的历史速率。
本发明实施例提供的分流节点装置发送分流数据包的历史速率、 单个 用户设备在分流节点装置中緩存的待发送分流数据包数量、 分流节点装置 为单个用户设备发送分流数据包的历史速率可以用作数据发送装置是否 需要向该分流节点装置继续发送数据的一个参考参数； 数据发送装置根据 所述分流节点装置发送分流数据包的历史速率可以估计出是否需要向分 流节点装置继续分流数据； 数据发送装置还可以根据所述单个用户设备在 分流节点装置中緩存的待发送分流数据包数量估计是否需要将该单个用 户设备的数据包信息发送给其它的分流节点装置、 让其它的分流节点装置 发送给该单个用户设备； 或者数据发送装置也可以根据所述分流节点装置 为单个用户设备发送分流数据包的历史速率估计是否需要将数据分流给 其它的分流节点装置、 让其它的分流节点装置将数据发送给该单个用户设 备。
本发明实施例提供一种数据分流方法， 图 2为本发明数据分流方法的 实施例的流程示意图二， 如图 2所示， 该方法包括以下步骤：
步骤 201 : 用户设备接收数据发送装置发送的第一汇报指示消息， 所 述第一汇报指示消息用于指示用户设备根据预设周期发送分流数据包报 告信息， 或用于指示用户设备每在接收到预设数目的数据包时发送分流数 据包报告信息。
具体地， 用户设备接收数据发送装置发送的第一汇报指示消息， 该第 一汇报指示消息用于指示用户设备以 T 为周期向数据发送装置反馈分流 数据包报告信息， 或者第一汇报指示消息还可用于指示用户设备以某个预 设门限向数据发送装置反馈分流数据包报告信息。
步骤 202: 用户根据接收的所述第一汇报指示消息向数据发送装置发 送分流数据包报告信息， 所述分流数据包报告信息包括分流节点标识， 以 及用户设备从所述分流节点装置接收到数据包的标识列表或从所述分流 节点装置接收到的最后一个数据包的标识。
具体地，无论用户设备以 T为周期还是以某个预设的门限向数据发送 装置发送分流数据包报告信息， 该分流数据包报告信息均包括分流节点标 识， 以及用户设备从所述分流节点装置接收到数据包的标识列表或从所述 分流节点装置接收到的最后一个数据包的标识。 其中， 分流节点标识可以 是分流节点装置的 MAC地址、 IP地址或者其他标识。 数据包的标识列表 可以是 TCP、 IP层序列号或者其他标识。
进一步， 所述分流数据包报告信息中还包括有用户设备从所述分流节 点装置接收分流数据包的历史速率
综上所述， 为了确定数据发送装置是否需要继续给分流节点装置分流 数据， 本发明实施例可通过如下的方法确定：
首先， 数据发送装置通过第一汇报指示消息配置用户设备一个 OPRR 的反馈周期 T,其中用于配置该参数的第一汇报指示消息的具体类型不限。
其次，用户设备以 T为周期向数据发送装置反馈从分流节点装置接收 到的分流数据包报告 OPRR信息。 该 OPRR信息中可以包括： 分流节点标 识、 接收到的数据包的标识列表或者接收到的最后一个数据包的标识 ID、 从该分流节点装置接收到的历史数据速率值 R。 分流节点标识可以是分流 节点装置的 MAC地址、 IP地址或者其他标识。数据包的标识可以是 TCP、 IP层序列号或者其他标识。历史数据速率值 R可以根据 UE—段时间内从 该分流节点装置接收的数据量估计得到。
再其次，数据发送装置根据该 OPRR中包含数据包信息和其分流到分 流节点装置的数据包信息， 能够估计出分流节点装置的 buffer中等待分流 的数据包数量。 例如如果数据发送装置已经向分流节点装置分流了 100个 数据包， 而根据用户设备上报的 OPRR信息， 用户设备从分流节点装置接 收到了 40个数据包， 那么数据发送装置可以估计出分流节点装置还有 60 个数据包等待传输。 数据发送装置可以根据该估计出 buffer中緩存的数据 包数量信息决定是否向分流节点装置分流。 如： 当数据包数量小于某门限 时， 例如小于 10个数据包时， 就向分流节点装置分流； 否则， 不向分流 节点装置分流数据。
本发明实施例提供的数据分流方法， 通过用户设备以预设周期向数据 发送装置反馈从分流节点装置接收到的数据包信息来确定数据发送装置 是否需要继续向分流节点装置分流数据， 当分流节点装置中緩存的待发送 数据包数量大于某个预设值时， 就不再向分流节点装置发送数据， 由此分 流节点装置 buffer中的数据包不会产生拥塞或者数据包延时增大， 甚至丟 包的现象而导致影响分流节点装置到用户设备的传输速率， 从另外一方面 来说， 本发明实施例提供的分流数据方法提高了分流节点装置的传输速 率； 当分流节点装置中緩存的待发送数据包数量小于某个预设值时， 数据 发送装置继续向分流节点装置发送数据， 使的分流节点装置的 buffer得到 了充分的利用， 从另一方面来讲， 也提高了分流节点装置的传输速率。
本发明实施例再提供一种方法来确定是否需要继续给分流节点装置 分流数据， 该方法具体为：
首先， 数据发送装置通过第一汇报指示消息配置用户设备一个 OPRR 的反馈门限 N, 其中， 用于配置该参数的第一汇报指示消息不限。
其次， 从上次反馈开始， 当用户设备从分流节点装置接收到的数据包 个数累积超过 N, 用户设备则向数据发送装置反馈从分流节点装置接收到 的数据包报告 OPRR信息。 该 OPRR信息中可以包括： 分流节点标识、 接 收到的数据包的标识列表或者接收到的最后一个数据包的标识 ID、从该分 流节点装置接收到的历史数据速率值 R。 分流节点标识可以是分流节点装 置的 MAC地址、 IP地址或者其他标识。 数据包的标识可以是 TCP、 IP层 序列号或者其他标识。历史数据速率值 R可以根据用户设备一段时间内从 该分流节点装置接收的数据量估计得到。
再其次，数据发送装置根据该 OPRR中包含数据包信息和其分流到分 流节点装置的数据包信息， 能够估计出分流节点装置的 buffer中等待分流 的数据包数量。 例如如果数据发送装置已经向分流节点装置分流了 100个 数据包， 而根据用户设备上报的 OPRR信息， 用户设备从分流节点装置接 收到了 40个数据包， 那么数据发送装置可以估计出分流节点装置还有 60 个数据包等待传输。 数据发送装置可以根据该估计的 buffer中緩存的数据 包数量信息决定是否向分流节点装置分流。 如： 当数据包数量小于某门限 时， 例如小于 10个数据包时， 就向分流节点装置分流； 否则， 不向分流 节点装置分流数据。
本发明实施例提供的分流数据的方法， 通过用户设备从上次反馈开始 到接收的数据包数量达到某一个预设数目时向数据发送装置反馈其接收 到的分流数据包报告信息， 从而使数据发送装置根据其发送给分流节点装 置的数据包总量估计出分流节点装置中緩存的待发送数据包数量， 由此数 据发送装置决定是否需要继续给分流节点装置分流数据， 从而提高了分流 节点装置的传输速率。
本发明实施例提供一种数据分流方法， 图 3为本发明数据分流方法的 实施例的流程示意图三， 如图 3所示， 该方法包括以下步骤：
步骤 301 : 接收数据发送装置发送的第二汇报指示消息， 所述第二汇 报指示消息用于指示分流节点装置根据预设周期发送緩存状态报告信息， 或用于指示分流节点装置每在发送预设数目的数据包时发送緩存状态报 告信息。
具体地， 分流节点装置接收数据发送装置发送的第二汇报指示消息， 该第二汇报指示消息用于指示分流节点装置以 T 为周期向数据发送装置 反馈緩存状态报告信息， 或者第二汇报指示消息还可用于指示分流节点装 置以某个数据门限向数据发送装置反馈緩存状态报告信息。
步骤 302: 根据接收的所述第二汇报指示消息向数据分流装置发送緩 存状态报告信息， 所述緩存状态报告信息中携带有分流节点装置中緩存的 待发送分流数据包数量。
具体地，无论分流节点装置以 T为周期还是以某个数据门限向数据发 送装置发送緩存状态报告信息， 该緩存状态报告信息均包括待发送分流数 据包数量。
进一步， 所述緩存状态报告信息中还包括有分流节点装置发送分流数 据包的历史速率、 单个用户设备在分流节点装置中緩存的待发送分流数据 包数量， 分流节点装置为单个用户设备发送分流数据包的历史速率
综上所述， 本发明实施例又提供了一种方法来确定是否需要继续给分 流节点装置分流数据， 该方法具体为：
首先， 数据发送装置通过第二汇报指示消息配置给分流节点装置一个
OBSR反馈周期 T, 以及一个 OBSR量化表， 其中， 用于配置该参数的第 二汇报指示消息不限。
其次，分流节点装置以 T为周期向数据发送装置反馈当前分流节点装 置的分流 buffer状态 艮告 OBSR信息。 OBSR中可包含： buffer中等待分 流的数据包数量、 单个用户设备在分流节点装置等待分流的数据包数量、 分流节点装置分流的历史总速率 Rt、分流节点装置到单个用户设备的历史 分流速率！"。 为降低 OBSR大小， 反馈的 buffer中数据量大小经过量化。 分流历史速率 Rt和 r可以根据分流节点装置一段时间内从该分流节点装置 成功分流的数据包数量估计得到。
再其次， 数据发送装置接收分流节点装置发送的 OBSR信息， 并获知 分流节点装置的 buffer中等待分流的数据包数量信息， 根据该数据包数量 信息决定是否向分流节点装置分流。 如： 当数据量小于某门限时， 例如小 于 10个数据包时， 就向分流节点装置分流； 否则， 不向分流节点装置分 流数据。
本发明实施例提供的数据分流的方法， 通过分流节点装置以预设周期 向数据发送装置反馈其 buffer中緩存的待发送数据包数量来使数据发送装 置确定是否需要继续向分流节点装置分流数据， 当分流节点装置中緩存的 待发送数据包数量大于某个预设值时， 就不再向分流节点装置发送数据， 由此分流节点装置 buffer中的数据包不会产生拥塞或者数据包延时增大， 甚至丟包的现象而导致影响分流节点装置到用户设备的传输速率， 从另外 一方面来说， 本发明实施例提供的分流数据方法提高了分流节点装置的传 输速率； 当分流节点装置中緩存的待发送数据包数量小于某个预设值时， 数据发送装置继续向分流节点装置发送数据， 使的分流节点装置的 buffer 得到了充分的利用，从另一方面来讲，也提高了分流节点装置的传输速率。
本发明实施例还提供了一种方法来确定是否需要继续给分流节点装 置分流数据， 该方法具体为：
首先， 数据发送装置通过第二汇报指示消息配置给分流节点装置一个 数据量门限 [B1,B2] , 以及一个 OBSR量化表， 其中用于配置该参数的第 二汇报指示消息不限。
其次， 当分流节点装置的分流 buffer中緩存的数据包数量小于 B1或 者大于 B2 时， 则分流节向数据发送装置反馈当前分流节点装置的分流 buffer状态报告 OBSR信息。 该 OBSR信息中可包含： buffer中等待分流 的数据包数量、 单个用户设备在分流节点装置等待分流的数据包数量、 分 流节点装置分流的历史总速率 Rt、分流节点装置到单个用户设备的历史分 流速率 r。 为降低 OBSR大小， 反馈的 buffer中数据量大小经过量化。 分 流历史速率 Rt和 r可以根据分流节点装置一段时间内从该分流节点装置成 功分流的数据量估计得到。
再其次， 数据发送装置接收分流节点装置发送的緩存状态报告 OBSR 信息， 并获知分流节点装置的 buffer中等待分流的数据包数量信息， 根据 该数据包数量信息决定是否向分流节点装置分流。 如： 当数据包数量小于 某门限时， 例如小于 10个数据包时， 就向分流节点装置分流； 否则， 不 向分流节点装置分流数据。
本发明实施例提供的分流数据的方法， 通过分流节点装置从上次反馈 开始到其 buffer中緩存的待发送数据包数量达到某一个预设数目时向数据 发送装置反馈其待发送的数据包数量信息， 从而使数据发送装置决定是否 需要继续给分流节点装置分流数据， 从而提高了分流节点装置的传输速 率。
