步骤 1002, 核心网设备根据 QOS信息生成业务数据的分流倾向指示; 分流倾向指示用于指示业务数据在第一资源上的调度倾向, 第一资源包括 采用非授权频谱的 LTE载波、 WLAN提供的传输资源或微基站提供的传输资 源。 其中,
在 QOS信息包括: AMBR、 ARP和 QCI时, 若 AMBR指示的速率大于 第一阈值、 ARP指示的优先级小于第一优先级且 QCI指示的延迟大于第二阈 值, 则核心网设备生成用于指示优先在第一资源上调度的分流倾向指示。

在接入网设备是图 1系列示出的主基站时,核心网设备向主基站发送分流 倾向指示; 在接入网设备是图 2系列示出的微基站时, 核心网设备通过主基站 向微基站转发分流倾向指示。 也即, 核心网设备先将分流倾向指示发送给主基 站, 然后由主基站向 基站转发该分流倾向指示。
步骤 1004,接入网设备接收业务数据的分流倾向指示;
在接入网设备是图 1系列示出的主基站时, 主基站接收核心网设备发送的 分流倾向指示; 在接入网设备是图 2系列示出的微基站时, 微基站接收核心网 设备通过主基站转发的所述分流倾向指示。
作为另一种可能的实现方式,核心网设备可以直接向主基站发送业务数据 的 QOS信息, 由主基站根据业务数据的 QOS信息生成分流倾向指示, 然后由 主基站向微基站发送分流倾向指示。 此时, 微基站接收主基站发送的分流倾向 指示, 该分流倾向指示是主基站接收到核心网设备发送的业务数据的 QOS信 息后根据业务数据的 QOS信息生成。
步骤 1005,接入网设备根据分流倾向指示分配用于传输业务数据的传输资 源;

步骤 1006, 接入网设备采用分配的传输资源传输业务数据。
在为业务数据分配的传输资源包括: 属于非第一资源的传输资源时, 接入 网设备通过授权频谱的 LTE载波向终端发送业务数据中与属于非第一资源的 传输资源对应的数据。
在为业务数据分配的传输资源包括: 属于第一资源的传输资源且第一资源 是非授权频谱的 LTE载波时, 接入网设备通过非授权频谱的 LTE载波向终端 发送业务数据中与属于第一资源的传输资源对应的数据;
在为业务数据分配的传输资源包括: 属于第一资源的传输资源且第一资源 是 WLAN提供的传输资源时, 接入网设备将业务数据中与属于第一资源的传 输资源对应的数据发送给 WLAN的无线接入点, 由无线接入点向终端转发该 数据;

需要补充说明的是, 若所述业务数据还包括上行业务数据, 所述接收业务 数据的分流倾向指示之后, 还包括:
接入网设备在分流倾向指示为 1个上下行共用的分流倾向指示时, 向终端 发送分流倾向指示, 以便终端根据分流倾向指示确定用于传输上行业务数据的 传输资源, 且根据确定的用于传输所述上行业务数据的传输资源传输所述上行 业务数据;
接入网设备在分流倾向指示包括单独的上行分流倾向指示时, 向终端发送 分流倾向指示中的上行分流倾向指示, 以便终端根据上行分流倾向指示确定用 于传输上行业务数据的传输资源, 且根据确定的用于传输所述上行业务数据的 传输资源传输所述上行业务数据。
当然, 若所述业务数据只包括上行业务数据的场景下, 接入网设备可以只 向终端发送分流倾向指示。
步骤 1007,接入网设备统计在传输业务数据时所使用的属于第一资源的传 输资源和 /或属于非第一资源的传输资源各自所对应的流量统计信息;
流量统计信息可以是属于第一资源的传输资源所对应的流量占总流量的 比值; 或者, 流量统计信息可以是属于非第一资源的传输资源所对应的流量占 总流量的比值, 或者, 流量统计信息还可以是属于第一资源的传输资源所对应 的流量与属于非第一资源的传输资源所对应的流量的比值。 只要流量统计信息 能够表示流量统计结果即可, 流量统计信息的具体形式不限。

在接入网设备是图 1系列示出的主基站时,核心网设备接收主基站直接上 报的流量统计信息; 在接入网设备是图 2系列示出的微基站时, 核心网设备接 收微基站通过主基站上报的流量统计信息。 步骤 1010, 核心网设备向计费网元发送流量统计信息。
由于流量统计信息可以用于计费、 统计传输资源的使用等多个用途, 所以 对核心网设备如何使用流量统计信息不做具体限定。 以流量统计信息用于计费 为例, 当核心网设备是移动管理实体 MME时, MME可以向计费网元发送流 量统计信息, 以便计费网元根据流量统计信息在计费时对属于第一资源的传输 资源和 /或属于非第一资源的传输资源进行差异化计费。
综上所述, 本实施例提供的数据分流方法, 通过接入网设备接收来自核心 网设备针对业务数据的分流倾向指示; 根据分流倾向指示分配用于传输业务数 据的传输资源; 采用分配的传输资源传输业务数据; 解决了采用非授权频谱、 WLAN提供的传输资源或微基站提供的传输资源等第一资源进行分流时,无法 保证传输过程的 QOS的问题; 达到了即便使用采用非授权频谱、 WLAN提供 的传输资源或微基站提供的传输资源等第一资源进行分流时, 也可以保证传输 过程的 QOS的效果。
