分流 (offload) 是指将移动数据业务从一个网络平滑的迁移到另一个 网络。 为实现用 WLAN为蜂窝网络分流, 第三代移动通信伙伴组织 (3rd Generation Partnership Project, 3 GPP)提出接入网发现和选择功能(Access Network Discovery and Selection Function, ANDSF) 来辅助终端进行接入 网的选择。 具体的, ANDSF 服务器与终端均支持开放移动联盟 ( Open Mobile Alliance, OMA ) 设备管理 ( Device Manage, DM ) 协议, 位于蜂窝网核心网中的 ANDSF服务器与终端通过 S 14接口进行通信, 从 而使得终端获得选网策略, 例如, 终端通过推 (push ) 方式, 即被动接收 ANDSF服务器发送的选网策略; 或者, 通过拉 (pull) 方式, 即终端主动 向 ANDSF査询选网策略。 然后, 根据获得的选网策略, 由终端自行进行 接入网的发现和选择。
另外, 也可以通过电气和电子工程学会 ( Institute of Electrical and Electronics Engineers , IEEE) 协会制定的相关机制, 实现用 WLAN为蜂 窝网络分流。 具体的, 终端获取 WLAN、 3G网络等的相关信息, 例如, 终端主动向 WLAN的接入设备发送探测请求帧 (Probe Request) ; 或者, 被动的接收 WLAN的接入设备发送信标帧(Beacon ) 从而获得 WLAN的 相关信息。 然后, 根据获取到的网络信息, 由终端自行进行接入网的发现 和选择。

图 1为本发明网络分流方法实施例一的流程图。 本实施例的执行主体 为第一网络控制器, 适用于当通信网络中存在多个接入网时, 由网络侧控 制终端接入行为的场景。 具体的, 本实施例包括如下歩骤:
101、 第一网络控制器接收终端的网络状态信息, 终端至少为一个, 网络状态信息为终端在对应的至少一个接入网中的状态信息, 其中, 第一 网络控制器为第一接入网的网络控制器。
当通信网络中存在至少一个接入网时, 各个接入网的网络控制器接收 通信网络中所有终端或部分终端在对应的接入网中的网络状态信息。 例 如, 当网络中存在两个接入网: WLAN网络和蜂窝网络时, 以 WLAN网 络控制器为第一网络控制器为例, WLAN网络控制器接收各终端在 WLAN 网络和蜂窝网络中的网络状态信息。
可选的, 第一网络控制器通过如下几种方式接收终端的网络状态信 息:
方式一、 第一网络控制器接收终端发送的网络状态信息。
该方式中, 第一网络控制器直接接收终端发送的、 经第一接入设备透 传的网络状态信息。 具体的, 第一网络控制器接收终端接入第一接入网之 前, 或者, 接入第一接入网之后发送的、 经第一接入设备透传的网络状态 信息。 该过程中, 接入设备对终端上报的网络状态信息不做任何处理, 而 是直接转发给第一网络控制器。
方式二、 第一网络控制器接收第一接入网的第一接入设备发送的、 指 示终端在第一接入网中状态的网络状态信息。
该方式中, 第一接入网的第一接入设备向第一网络控制器上报终端在 第一接入网中的网络状态信息。 具体的, 第一接入设备可以在终端准备接 入该第一接入设备以访问第一接入网时, 或者, 在终端已经接入该第一接 入设备时, 搜集并获取终端在第一接入网中的状态信息并向第一网络控制 器发送。
方式三、第一网络控制器接收第一接入网外的其他接入网的网络控制 器发送的、 指示终端在第一接入网之外的其他接入网中状态的网络状态信 息。
该方式中, 第一网络控制器接收到的终端的网络状态信息是由第一接 入网外的其他接入网的接入设备在终端接入该接入网之前, 或接入该接入 网之后发送的网络状态信息。 例如, 上述 WLAN网络控制器接收到的蜂 窝网络控制器发送的网络状态信息, 其中, 蜂窝网络控制器发送的网络状 态信息可以是终端在接入蜂窝网络之前, 或者在接入蜂窝网络之后, 发送 的终端在蜂窝网络中的状态信息。
可选的, 上述方式一中, 第一网络控制器接收到的终端发送的网络状 态信息, 包括: 终端在第一网络控制器所属的第一接入网中的状态信息; 和 /或, 终端在除第一接入网之外的其他接入网中的状态信息。
具体的, 终端在向第一网络控制器发送网络状态信息时, 可仅发送其 在第一网络控制器所属的第一接入网中的状态信息; 或者, 除了向第一网 络控制器发送其在第一网络控制器所属的第一接入网中的状态信息之外, 还可以将其在其他网络中的状态信息发送给第一网络控制器。 例如, 上述 当第一网络控制器为 WLAN网络控制器时, WLAN网络控制器接收到的 终端上报的网络状态信息包括除终端在 WLAN网络中的网络状态信息外, 还可包括终端在蜂窝网络中的网络状态信息。 102、 第一网络控制器根据网络状态信息, 为终端生成分流策略。 本歩骤中, 第一网络控制器根据接收到的各网络状态信息, 生成各终 端的分流策略。
可选的, 分流策略包括下述信息中的至少一种: 接入网指示信息, 指示各终端应接入的接入网信息; 接入设备指示信息, 指示各终端应接入 的接入网的接入设备信息; 业务指示信息, 指示各终端的业务信息和该业 务信息指示的业务应接入的接入网的接入网信息。
具体的, 第一网络控制器根据接收到的各网络状态信息, 对于未接入 第一接入网的终端, 生成的分流策略可指示该终端接入第一接入网或其他 接入网, 或者, 仅指示该终端将部分业务接入第一接入网; 对于已接入第 一接入网的终端, 生成的分流策略可指示该终端继续停留在第一接入网, 或者, 完全切换到其他接入网, 或者, 将部分业务切换到其他接入网。
进一歩的,分流策略指示终端可接入、或部分业务可接入第一接入网, 则分流策略还包括指示终端应接入的接入设备的信息。
103、 第一网络控制器向终端发送分流策略; 和 /或, 向至少一个接入 网的接入设备发送分流策略。
在为各终端生成分流策略后, 第一网络控制器向网络侧设备或终端发 送分流策略, 以使得网络侧设备或终端按照分流策略执行分流。
可选的, 在为各终端生成分流策略后, 第一网络控制器向终端发送分 流策略, 使得终端按照分流策略进行接入网的策略。
可选的, 在为各终端生成分流策略后, 第一网络控制器向第一接入设 备发送分流策略, 使得第一接入设备按照分流策略, 仅接入指定的终端。
具体的, 第一接入设备也可根据自身默认的接入策略和接收到的分流 策略控制终端的接入行为, 其中, 默认的接入策略例如为: 允许任意终端 接入、 不允许某些终端或某些业务接入等; 分流策略的内容包含允许接入 和不允许接入的终端的信息或者仅包含允许接入的终端的信息等。
例如, 当第一接入网为 WLAN时, 分流策略可包含允许接入和不允 许接入的所有终端的信息, 如果第一接入设备默认允许任意终端接入, 此 时第一接入设备( AP )会先对所有终端发送的探测请求帧(Probe Request) 进行响应, 回应探测响应帧 (Probe Response ) 进而允许终端接入。 由于 分流策略包含允许接入和不允许接入的所有终端的信息, 则第一接入设备 再根据分流策略, 对某些终端或某一些终端的某些业务进行去关联, 如关 闭某些终端或某些业务等。 该过程中, 第一接入设备先允许终端或终端的 所有业务接入, 再根据分流策略对某一些终端或某一些终端的某一些业务 进行去关联。
再如, 当第一接入网为 WLAN时, 分流策略可仅包含允许接入的终 端的信息。 如果第一接入设备默认不允许任意终端接入, 即第一接入设备 ( AP )会默认对所有终端发送的探测请求帧(Probe Request)都不进行响 应, 由于分流策略仅包含允许接入的终端的信息。 AP在收到分流策略后, 根据分流策略仅对允许接入的终端发送的探测请求帧 (Probe Request) 进 行响应, 发送探测响应帧 (Probe Response ) 进而允许终端接入, 而对于 不被允许接入的各终端, 则对其发送的 Probe Request不进行响应。
可选的, 在为各终端生成分流策略后, 第一网络控制器向第一接入网 外的其他接入网的接入设备或网络控制器发送分流策略, 使得各接入设备 或网络控制器执行分流。
本发明实施例提供的网络分流方法, 第一网络控制器根据接收到的网 络状态信息, 为各终端生成分流策略并向网络侧设备或终端发送, 使得网 络侧设备或终端按照分流策略执行分流, 从而实现网络侧对终端分流的控 制。

可选的, 第一网络控制器接收终端在第一接入网中的第一网络状态信 息之后, 第一网络控制器根据第一网络状态信息, 生成第一分配列表, 第 一分配列表指示各终端与第一接入网的第一接入设备的对应关系; 第一 网络控制器根据第一分配列表和第二分配列表, 为终端生成分流策略。

201、 WLAN网络控制器接收终端的第一网络状态信息。
具体的, 本歩骤可包括如下子歩骤:
