Description

一种业务处理的方法、装置及系统 技术领域
本发明涉及通信技术领域，尤其涉及一种业务处理的方法、装置及系统。
背景技术
在演进的分组核心(Evolved Packet Core，EPC)网络中，由于移动网关的控制面与转发面未分离使得EPC网络不能灵活扩容，为了解决该问题，现有技术中将移动网关的控制面与转发面进行了分离，如图1所示，为EPC网络中的移动网关控制和转发功能分离的网络架构示意图，其中，移动网关的控制面101可以决策UE(User Equipment，用户设备)发送的报文的相关的数据处理规则，并通过控制面101与转发面102之间的接口将该数据处理规则下发给转发面102，转发面102根据该数据处理规则对基站103(外部网络104)发送的报文进行处理后向外部网络104(基站103)发送。
其中，转发面集成了用户IP(Internet Protocol，因特网协议)地址的锚定点功能以及多种业务处理功能，因此，转发面具有地址资源并且包括计算资源。转发面具有的地址资源决定了转发面可以服务的用户数量，转发面包括的计算资源决定了转发面在同一时刻可以同时处理的报文数量。转发面中的计算资源在设备出厂后一般固定不变，转发面中的地址资源通过配置的形式分配给转发面设备，更新地址资源配置涉及到周边网元的路由信息更新，一般无法实时实现。
由于EPC网络中的用户数量以及同一时刻所有用户发送的报文数量并不是一成不变的，在转发面的地址资源不足或者计算资源不足时，需要增加转发面，而在EPC网络中的用户数量增加，但是同 一时刻所有用户发送的报文数量不变的情况下，增加转发面会导致计算资源的浪费；在EPC网络中的用户数量不变，但是同一时刻所有用户发送的报文数量增加的情况下，增加转发面会导致地址资源的浪费；即使在用户数量增加、同一时刻所有用户发送的报文数量也增加的情况下，也不能保证不会产生地址资源或计算资源的浪费。

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。
本文中字符“/”，一般表示前后关联对象是一种“或”的关系。本文中的“多个”是指两个或者两个以上。
实施例一
本发明实施例提供一种业务处理方法，如图2所示，包括：
201、控制器控制第一节点将接收到的报文发送至处理网络。
202、所述控制器控制所述处理网络对所述报文进行处理后发送至第二节点。
其中，所述第一节点为基站或与所述基站相连接的网元，所述第二节点为路由功能实体；或者，所述第一节点为所述路由功能实体，所述第二节点为所述基站或与所述基站相连接的网元；所述路由功能实体为用户IP地址的锚定点。
示例性的，本发明实施例提供的方法至少可以应用于EPS (Evolved Packet System，演进分组系统)网络(下文中提到的网络均指该网络，网络系统的架构示意图均指该网络的系统架构示意图)，EPS网络包括E-UTRAN(Evolved Universal Terrestrial Radio Access Network，演进的通用陆地无线接入网)和EPC网络。
本发明中，所述路由功能实体为IP地址锚定点，指该路由功能实体负责为经该路由功能实体分配给UE的IP地址提供IP路由能力。即该路由功能实体负责接收目的IP为该IP地址的下行报文(从外部网络发往UE的报文)，并将源IP为该IP地址的上行报文(从UE发往外部网络的报文)发送到外部网络。当UE在一定范围内移动时，该路由功能实体不变，以屏蔽UE移动对外部网络的影响，实现该IP地址的锚定。该情况下，路由功能实体具有地址资源。本发明实施例中的外部网络是指PDN(Packet Data Network，分组数据网络)。
上述方法在具体实现时可以基于下文中的图16所示的网络系统的架构，基站(路由功能实体)接收到UE(外部网络)发送的报文后，将该报文转发至处理网络，处理网络将该报文进行处理后发送至路由功能实体(基站)，路由功能实体(基站)接收到该报文后，将该报文转发至外部网络(UE)。图16中通过一条实线示例性的示出了当第一节点为基站时报文的路径。本发明实施例中提到的与基站相连接的网元和本发明实施例中提到的基站具备同样的功能，因此本发明实施例中仅以基站为例进行说明。
本发明实施例中提到的UE包括但不限于手机、网络接入终端设备、物联网终端设备等。基站指为UE提供无线接入的设备，包括但不限于eNodeB(evolved Node B，演进的NodeB)、WiFi AP(Wireless Fidelity Access Point，无线保真接入点)、WiMAX BS(Worldwide Interoperability for Microwave Access Base Station，全球微波互联接入基站)等。需要说明的是，图16至图20中，为了方便描述，均示出了UE和外部网络。需要说明的是，本发明实施例中的处理网络是 指由至少一个网络节点组成的用于对报文进行处理的网络实体。
本发明实施例提供的方法，将转发面分为了处理网络和路由功能实体，处理网络用于对报文进行处理，因此，处理网络中包括计算资源，路由功能实体作为用户IP地址的锚定点，具有地址资源。在网络中的地址资源不足时，可以增加路由功能实体；在网络中的计算资源不足时，可以增加处理网络。因此，相比现有技术而言，本发明实施例提供的方法可以减少地址资源或者计算资源的浪费。
可选的，所述处理网络包括至少一个处理功能实体。该情况下，网络系统的架构可以参见下文中图17或图18。
具体的，处理功能实体用于对接收到的报文进行处理，对报文进行处理包括但不限于执行QoS(Quality of Service，服务质量)控制、在线/离线计费、DPI(Deep Packet Inspection，深度包检测)、合法监听、TCP(Transmission Control Protocol，传输控制协议)加速和HTTP(HyperText Transfer Protocol，超文本传输协议)头增强等。一个处理功能实体可以对报文进行多种类型的处理，一个处理功能实体也可以对报文进行一种类型的处理，该情况下，处理功能实体可以为QoS处理实体、计费处理实体或DPI处理实体等，该情况下，由于本发明实施例中每个处理功能实体只有一种处理功能，因此，可以使得QoS控制、在线/离线计费、DPI等复杂功能可以灵活迁移。当网络系统对具有某一种处理功能的处理功能实体有较大的需求时，可以仅仅增加该处理功能实体，而不用增加处理网络，使得各个处理功能实体都可以灵活迁移。下文中均以一个处理功能实体包括一种报文处理功能为例进行说明。
网络系统中的控制器还可以包括路由控制器和至少一个处理控制器，该情况下，使得控制面的路由控制功能和处理控制功能分离，以提高控制面更为灵活的部署和协同能力。另外，网络系统中还可以包括转发器。
上述方法包括多种具体的实现方式，以下分别进行描述。
在对以下四种实现方式中的每一种实现方式进行描述的过程中，提到的业务流标识均指同一业务流标识，提到的报文均指携带该业务流标识的报文，提到的处理策略、第一转发策略和第二转发策略均指针对该业务流标识生成的处理策略和转发策略(针对不同的业务流标识生成的处理策略、第一转发策略和第二转发策略可能不同)。业务流标识可以为UE的IP地址或业务流的IP五元组等。
实现方式一
图17所示的网络系统的架构示意图中包括控制器、基站、路由功能实体和处理网络，处理网络中包括至少一个处理功能实体(图17中以处理网络中包括4个处理功能实体为例进行绘制)，在如下图17所示的网络系统的架构下，如图3所示，上述方法的具体实现过程包括：
301、控制器向第一节点发送第一转发策略，所述第一转发策略用于控制所述第一节点将接收到的报文发送至第1处理功能实体。
其中，第1处理功能实体为上述至少一个处理功能实体中的第一个处理报文的处理功能实体。
第一转发策略可以根据业务流标识和第1处理功能实体的标识生成，业务流标识可以为UE的IP地址或业务流的IP五元组等。当UE初始接入网络时，UE的IP地址可以由路由功能实体进行分配并发送给控制器，也可以由控制器根据预配置的路由功能实体对应的IP地址段进行分配。UE的IP地址可以是IPv4(Internet Protocol Version 4,因特网协议版本4)地址或IPv6(Internet Protocol Version 6,因特网协议版本6)地址等。当业务流标识为业务流的IP五元组时，控制器可以根据UE的IP地址、UE发送的用于请求接入网络的接入请求中的目的IP或UE发送的业务请求确定业务流标识。
需要说明的是，控制器在确定业务流标识之后，可以根据业务 流标识确定携带该业务流标识的报文对应的处理逻辑，即所述报文经过的处理功能实体。
处理功能实体的标识可以为处理功能实体的IP地址、MAC(Media Access Control，媒体接入控制)地址、连接端口号或隧道标识等。
302、控制器向处理网络中的一个或多个处理功能实体发送对应的处理策略，处理策略用于控制接收到该处理策略的处理功能实体根据该处理策略对接收到的报文进行处理。
其中，上述一个或多个处理功能实体为处理报文的所有的处理功能实体，下文中为了方便描述，将处理网络中包括的所有的处理功能实体记为N个处理功能实体，将处理报文的所有的处理功能实体记为M个处理功能实体，M个处理功能实体中包括第1处理功能实体，1≤M≤N，M为整数。
需要说明的是，网络系统中包括N个处理功能实体，但是在对报文进行处理时，可能只有其中的一个或多个处理功能实体对该报文进行处理。
具体的，控制器可以根据业务流标识生成每个处理功能实体对应的处理策略，一个处理功能实体对应一个处理策略。
303、控制器向M个处理功能实体发送对应的第二转发策略，第二转发策略用于控制接收到该第二转发策略的处理功能实体根据该第二转发策略对经该处理功能实体处理后的报文进行转发。
具体的，控制器向M个处理功能实体中的每个处理功能实体发送对应的第二转发策略和处理策略。
示例性的，当报文需要进行QoS控制处理，再进行DPI处理即可处理完毕时，M可以等于2，M个处理功能实体可以为QoS处理实体和DPI处理实体。
M个处理功能实体对应的第二转发策略可以相同也可以不同。 当M个处理功能实体对应的第二转发策略相同时，第二转发策略可以为根据业务流标识、M个处理功能实体的标识及第二节点的标识生成的一个总的转发策略；当M个处理功能实体对应的第二转发策略不同时，一个处理功能实体对应的第二转发策略可以根据业务流标识和该处理功能实体对应的下一节点的标识生成，一个处理功能实体对应的下一节点是指该处理功能实体对接收到的报文进行处理后需要发送的目标节点。
基于图17所示的网络系统的架构，以第一节点为基站，第二节点为路由功能实体(假设路由功能实体的标识为B)为例，假设报文在四个处理功能实体中的处理顺序为：标识为1的处理功能实体1—标识为2的处理功能实体2—标识为3的处理功能实体3—标识为4的处理功能实体4。该情况下，处理功能实体1即第1处理功能实体。报文经过基站后，再经过四个处理功能实体处理后转发至路由功能实体，路由功能实体将接收到的报文转发至外部网络。图17中通过实线指示该报文的路径。
该情况下，当4个处理功能实体对应的第二转发策略相同时，针对上述业务流标识的第二转发策略的一种形式可以为：1—2—3—4—B，每个处理功能实体接收到该第二转发策略时，根据自身的标识以及该第二转发策略即可确定自身对应的下一节点。当4个处理功能实体对应的第二转发策略不同时，以处理功能实体1为例，处理功能实体1对应的第二转发策略中可以包含业务流标识和标识2，处理功能实体1在接收到报文时，根据该第二转发策略即可确定将该报文进行处理后转发至标识为2的节点(即处理功能实体2)。以处理功能实体4为例，处理功能实体4对应的第二转发策略中可以包含业务流标识和标识B，处理功能实体4在接收到报文时，根据该第二转发策略即可确定将该报文进行处理后转发至标识为B的节点(即路由功能实体)。每个处理功能实体根据其对应的第二转发策 略可以确定自身对应的下一节点。
其中，本发明实施例中对步骤301、步骤302和步骤303的执行顺序不做具体限定。
304、第一节点接收控制器发送的第一转发策略；当第一节点接收到报文时，根据第一转发策略将接收到的报文转发至第1处理功能实体。
具体的，由于第一转发策略根据业务流标识和第1处理功能实体的标识生成，在第一节点接收到报文时，若该报文携带上述业务流标识，则根据第一转发策略确定将该报文转发至第1处理功能实体。
基于图17中的实线指示的路径中，当基站接收到报文时，根据第一转发策略将接收到的报文转发至处理功能实体1。
305、M个处理功能实体中的每个处理功能实体接收控制器发送的对应的处理策略；当一个处理功能实体接收到报文时，根据该处理功能实体对应的处理策略对该报文进行处理。
具体的，由于处理策略根据上述业务流标识生成，因此，当处理功能实体接收到报文时，若该报文携带该业务流标识，则该处理功能实体根据该处理策略对报文进行处理。
306、M个处理功能实体中的每个处理功能实体接收控制器发送的对应的第二转发策略；当一个处理功能实体根据该处理功能实体对应的处理策略对报文进行处理后，根据该第二转发策略对处理后的报文进行转发。
示例性的，基于图17中的实线指示的路径中，当报文到达基站时，基站根据第一转发策略将该报文转发至处理功能实体1，处理功能实体1根据接收到的处理策略和第二转发策略将该报文进行处理后转发至处理功能实体2；处理功能实体2根据接收到的处理策略和第二转发策略将该报文进行处理后转发至处理功能实体3；处理功能 实体3和处理功能实体4同理，则报文经过处理功能实体1、处理功能实体2、处理功能实体3和处理功能实体4处理并转发后即可到达路由功能实体。
在一种可实现的方式中，控制器也可以将第二转发策略携带在处理策略中，该情况下，步骤303和步骤306可以省去，处理功能实体可以直接根据处理策略对报文进行处理并转发。另外，控制器可以将第二转发策略和处理策略包含在同一消息中向处理功能实体发送。
在另一种可实现的方式中，第一转发策略和第二转发策略也可以相同，该情况下，第一转发策略和第二转发策略可以为根据报文转发的整条路径中的各个节点的标识生成的转发策略。
具体的，当第二节点为基站时，基站接收到M个处理功能实体中的最后一个处理报文的处理功能实体发送的报文后，将该报文转发至UE；当第二节点为路由功能实体时，路由功能实体接收到M个处理功能实体中的最后一个处理报文的处理功能实体发送的报文后，将该报文转发至外部网络。
实现方式二
图19所示的网络系统的架构示意图中包括路由控制器、至少一个处理控制器(图19中以1个处理控制器为例进行绘制)、基站、路由功能实体和处理网络，处理网络中包括N个处理功能实体(图19中以4个处理功能实体为例进行绘制)，基于图19所示的网络系统的架构，该情况下，如图4所示，上述方法的具体实现过程包括：
401、路由控制器向第一节点发送第一转发策略，所述第一转发策略用于控制所述第一节点将接收到的报文发送至第1处理功能实体。
具体的，实现方式二中的相关解释可以参见实现方式一。
第一转发策略可以根据业务流标识和第1处理功能实体的标识 生成，业务流标识可以为UE的IP地址或业务流的IP五元组等。当UE初始接入网络时，UE的IP地址可以由路由功能实体进行分配并发送给路由控制器，或者发送给路由控制器和上述至少一个处理控制器，也可以由路由控制器根据预配置的路由功能实体对应的IP地址段进行分配。
具体的，当业务流标识为业务流的IP五元组时，路由控制器和上述至少一个处理控制器确定业务流标识的方法至少可以通过以下几种方式实现：
方式一：在用户通过基站向网络发起接入请求时，至少一个处理控制器和路由控制器均接收该接入请求，并根据该接入请求中包括的目的IP地址以及第一预配置策略生成业务流标识；或者，至少一个处理控制器和路由控制器根据UE的IP地址以及第二预配置策略生成业务流标识。

方式三：在用户通过基站向网络发起业务请求时，至少一个处理控制器和路由控制器均接收该业务请求，由于业务请求中包括业务流标识，至少一个处理控制器和路由控制器可以根据该业务请求确定业务流标识。
402、至少一个处理控制器向M个处理功能实体中的每个处理功能实体发送对应的处理策略，处理策略用于控制接收到该处理策略的处理功能实体根据该处理策略对接收到的报文进行处理。
其中，当网络系统中只有一个处理控制器时，步骤402包括：处理控制器向N个处理功能实体中的M个处理功能实体中的每个处理功能实体发送对应的处理策略。当网络系统有N个处理控制器时，步骤402包括：N个处理控制器中的M个处理控制器向对应的N个处理功能实体中的M个处理功能实体中的每个处理功能实体发送对应的处理策略，其中，一个处理控制器对应一个处理功能实体，一个处理功能实体对应一个处理策略。
具体的，当网络系统中只有一个处理控制器时，处理控制器可以根据业务流标识生成每个处理功能实体对应的处理策略；当网络系统中有N个处理控制器时，N个处理控制器中的M个处理控制器分别根据业务流标识生成M个处理功能实体对应的处理策略。
403、路由控制器向M个处理功能实体中的每个处理功能实体发送对应的第二转发策略，第二转发策略用于控制接收到该第二转发策略的处理功能实体根据该第二转发策略对经该处理功能实体处理后的报文进行转发。
示例性的，当报文需要经过QoS控制处理，再经过DPI处理即可处理完毕时，M可以等于2，M个处理功能实体可以为QoS处理实体和DPI处理实体。
M个处理功能实体对应的第二转发策略可以相同也可以不同，具体可参见实现方式一中的描述。
基于图19所示的网络系统的架构，以第一节点为基站，第二节点为路由功能实体(假设路由功能实体的标识为B)为例，假设报文在四个处理功能实体中的处理顺序为：标识为1的处理功能实体1—标识为2的处理功能实体2—标识为3的处理功能实体3—标识为4的处理功能实体4。该情况下，处理功能实体1即第1处理功能实体。报文经过基站后，再经过四个处理功能实体处理后转发至路由功能实体，路由功能实体将接收到的报文转发至外部网络。图19 中通过实线指示该报文的路径。
该情况下，当4个处理功能实体对应的第二转发策略相同时，针对上述业务流标识的第二转发策略的一种形式可以为：1—2—3—4—B，每个处理功能实体接收到该第二转发策略时，根据自身的标识以及该第二转发策略即可确定自身对应的下一节点。当4个处理功能实体对应的第二转发策略不同时，以处理功能实体1为例，处理功能实体1对应的第二转发策略中可以包含业务流标识和标识2，处理功能实体1在接收到报文时，根据该第二转发策略即可确定将该报文进行处理后转发至标识为2的节点(即处理功能实体2)。以处理功能实体4为例，处理功能实体4对应的第二转发策略中可以包含业务流标识和标识B，处理功能实体4在接收到报文时，根据该第二转发策略即可确定将该报文进行处理后转发至标识为B的节点(即路由功能实体)。每个处理功能实体根据其对应的第二转发策略可以确定自身对应的下一节点。
其中，本发明实施例中对步骤401、步骤402和步骤403的执行顺序不做具体限定。
404、第一节点接收路由控制器发送的第一转发策略；当第一节点接收到报文时，根据第一转发策略将接收到的报文转发至第1处理功能实体。
具体的，由于第一转发策略根据业务流标识和第1处理功能实体的标识生成，在第一节点接收到报文时，若该报文携带上述业务流标识，则根据第一转发策略确定将该报文转发至第1处理功能实体。
基于图19中的实线指示的路径中，当第一节点接收到报文时，根据第一转发策略将接收到的报文转发至处理功能实体1。
405、M个处理功能实体中的每个处理功能实体接收上述至少一个处理控制器发送的对应的处理策略；当一个处理功能实体接收到 报文时，根据该处理功能实体对应的处理策略对该报文进行处理。
具体的，由于处理策略根据上述业务流标识生成，因此，当处理功能实体接收到报文时，若该报文携带该业务流标识，则该处理功能实体根据该处理策略对报文进行处理。
406、M个处理功能实体中的每个处理功能实体接收路由控制器发送的对应的第二转发策略；当一个处理功能实体根据该处理功能实体对应的处理策略对报文进行处理后，根据该第二转发策略对处理后的报文进行转发。
示例性的，基于图19中的实线指示的路径中，当报文到达基站时，基站根据第一转发策略将该报文转发至处理功能实体1，处理功能实体1根据接收到的处理策略和第二转发策略将该报文进行处理后转发至处理功能实体2；处理功能实体2根据接收到的处理策略和第二转发策略将该报文进行处理后转发至处理功能实体3；处理功能实体3和处理功能实体4同理，则报文经过处理功能实体1、处理功能实体2、处理功能实体3和处理功能实体4处理并转发后即可到达路由功能实体。
具体的，当第二节点为基站时，基站接收到M个处理功能实体中的最后一个处理报文的处理功能实体发送的报文后，将该报文转发至UE；当第二节点为路由功能实体时，路由功能实体接收到M个处理功能实体中的最后一个处理报文的处理功能实体发送的报文后，将该报文转发至外部网络。
在一种可实现的方式中，至少一个处理控制器也可以将第二转发策略携带在处理策略中，该情况下，第二转发策略可以由至少一个处理控制器生成，步骤403和步骤406可以省去，步骤402包括：至少一个处理控制器向N个处理功能实体中的M个处理功能实体中的每个处理功能实体发送对应的处理策略，所述处理策略中包括所述第二转发策略。另外，至少一个处理控制器可以将第二转发策略 和处理策略包含在同一消息中向处理功能实体发送。
在另一种可实现的方式中，第一转发策略和第二转发策略也可以相同，该情况下，第一转发策略和第二转发策略可以为根据报文转发的整条路径中的各个节点的标识生成的转发策略。
该情况下，由于路由控制器仅仅下发第一转发策略，因此，路由控制器中可以不具备根据每种业务流标识确定该业务流标识对应的处理逻辑的功能，那么路由控制器需要获取第1处理功能实体的标识用于生成第一转发策略。具体获取方式包括：所述至少一个处理控制器确定所述第1处理功能实体，并由目标处理控制器向所述路由控制器发送所述第1处理功能实体的标识；所述目标处理控制器为所述至少一个处理控制器中的任意一个处理控制器；所述路由控制器，还用于接收所述目标处理控制器发送的所述第1处理功能实体的标识。
具体的，第1处理功能实体可以为预配置的，例如，每个报文都可以首先进行QoS控制处理，则第1处理功能实体为QoS处理实体，第1处理功能实体也可以为上述至少一个处理控制器协商确定的。
实现方式三
图18所示的网络系统的架构示意图在图17的基础上还包括转发器(图18中以2个处理功能实体为例进行绘制)，图20所示的网络系统的架构示意图在图19的基础上还包括转发器(图20中以2个处理功能实体和2个处理控制器为例进行绘制)。该实现方式可以基于图18或图20所示的网络系统的架构下，其中，当基于图18所示的网络系统的架构时，网络系统中包括一个控制器，步骤501至步骤503的执行主体均为控制器；当基于图20所示的网络系统的架构时，网络系统中包括路由控制器和至少一个处理控制器，步骤501和步骤503的执行主体为路由控制器，步骤502的执行主体为上述 至少一个处理控制器。
如图5所示，上述方法在具体实现时包括：
501、向第一节点发送第一转发策略。
第一转发策略用于控制第一节点将接收到的报文转发至转发器。第一转发策略可以根据业务流标识和转发器的标识生成。具体关于业务流标识的描述可以参见实现方式一。转发器的标识可以为转发器的IP地址、MAC地址、连接端口号或隧道标识等。
需要说明的是，当基于图18(图20)所示的网络系统的架构下时，控制器(路由控制器)在确定业务流标识之后，可以根据业务流标识确定携带该业务流标识的报文对应的处理逻辑，即所述报文经过的处理功能实体。
502、向M个处理功能实体中的每个处理功能实体发送对应的处理策略。
该实现方式及实现方式四中的M个处理功能实体与实现方式一中的M个处理功能实体的含义相同。
具体的，可以根据业务流标识生成每个处理功能实体对应的处理策略，一个处理功能实体对应一个处理策略，向一个处理功能实体发送的处理策略用于该处理功能实体根据该处理策略对接收到的报文进行处理。
503、向转发器发送第二转发策略。
具体的，第二转发策略可以根据业务流标识、M个处理功能实体的标识和第二节点的标识生成。基于图18或图20所示的网络系统的架构，以第一节点为基站，第二节点为路由功能实体(假设路由功能实体的标识为B)为例，报文在2个处理功能实体中的处理顺序为：标识为1的处理功能实体1—标识为2的处理功能实体2。该情况下，针对上述业务流标识的第二转发策略的一种形式可以为：1—2—B。转发器接收到该第二转发策略后，当接收到来自处理功能 实体1的报文时，根据该第二转发策略即可确定将要转发的下一节点为标识为2的节点(即处理功能实体2)。图18和图20中通过实线指示该报文的路径。
需要说明的是，本发明只是示例性的示出了一种该第二转发策略的形式，并不代表只有上述一种形式。例如，当转发器的标识为C时，上文中的针对上述业务流标识的第二转发策略的一种形式还可以为：1—C—2—C—B。
其中，本发明实施例中对步骤501、步骤502和步骤503的执行顺序不做具体限定。
504、第一节点接收第一转发策略；当第一节点接收到报文时，根据第一转发策略将接收到的报文转发至转发器。
具体的，由于第一转发策略根据业务流标识和转发器的标识生成，在第一节点接收到报文时，根据第一转发策略即可确定该报文需要转发的下一节点为转发器。
基于图18或图20中的实线指示的路径中，当基站接收到报文时，根据第一转发策略将接收到的报文转发至转发器。
505、M个处理功能实体中的每个处理功能实体接收对应的处理策略；当一个处理功能实体接收到转发器发送的报文时，根据自身对应的处理策略对接收到的报文进行处理后转发至转发器。
具体的，每个处理功能实体对应的下一节点可以预配置为转发器，或者，每个处理功能实体对应的处理策略中可以添加转发器的标识，添加的该标识用于告知该处理功能实体对应的下一节点。
506、转发器接收第二转发策略，并根据第二转发策略对接收到的报文进行转发，以使得报文经过M个处理功能实体依次处理后到达第二节点。
具体的，转发器可以根据第二转发策略执行以下动作：当转发器接收到第三节点发送的报文时，将该报文转发至第四节点。其中， 当所述第三节点为所述第一节点时，所述第四节点为第1处理功能实体；当所述第三节点为第M处理功能实体时，所述第四节点为所述第二节点；当M≥2、且所述第三节点为第m处理功能实体时，所述第四节点为第m+1处理功能实体，所述报文在所述M个处理功能实体中的处理顺序依次为所述第1处理功能实体至所述第M处理功能实体，1≤m≤M-1，M≤N，m、M均为整数。
需要说明的是，当M＝1时，转发器接收到第1处理功能实体发送的报文后，直接根据第二转发策略将该报文转发至路由功能实体。
示例性的，基于图18或图20中的实线指示的路径中，当报文到达基站时，基站根据第一转发策略将该报文转发至转发器，转发器根据第二转发策略确定报文经过的节点依次为：标识为1的节点(即处理功能实体1)—标识为2的节点(即处理功能实体2)—标识为B的节点(即路由功能实体)，因此，转发器根据第二转发策略将接收到的基站发送的报文转发至处理功能实体1，处理功能实体1根据对应的处理策略将接收到的转发器发送的报文进行处理后转发至转发器；转发器接收到处理功能实体1发送的报文后，根据第二转发策略将该报文转发至处理功能实体2，处理功能实体2根据对应的处理策略将接收到的转发器发送的报文进行处理后转发至转发器；转发器接收到处理功能实体2发送的报文后，根据第二转发策略将该报文转发至路由功能实体。
具体的，当第二节点为基站时，基站接收到转发器发送的报文时，将该报文转发至UE；当第二节点为路由功能实体时，路由功能实体接收到转发器发送的报文时，将该报文转发至外部网络。
需要说明的是，当基于图18所示的网络系统的架构时，第一转发策略、第二转发策略和处理策略均由控制器生成。当基于图20所示的网络系统的架构时，当网络系统中只有一个处理控制器时，步骤502包括：处理控制器向N个处理功能实体中的M个处理功能实 体中的每个处理功能实体发送对应的处理策略。当网络系统中有N个处理控制器时，步骤502包括：N个处理控制器中的M个处理控制器向对应的N个处理功能实体中的M个处理功能实体发送对应的处理策略，其中，一个处理控制器对应一个处理功能实体。相应的，第一转发策略和第二转发策略由路由控制器生成，处理策略由上述至少一个处理控制器生成。
在一种可实现的方式中，第一转发策略和第二转发策略也可以相同，该情况下，第一转发策略和第二转发策略可以为根据报文转发的整条路径中的各个节点的标识生成的转发策略。
在实现方式三中，网络系统中增加了转发器，相比实现方式一，使得控制器或路由控制器不需要再向每个处理功能实体发送第二转发策略，因此，可以减少控制信令的条数。
在上述实现方式中，需要说明的是，基站中可能包含多个业务流标识对应的多个第一转发策略，一个业务流标识对应一个第一转发策略，当基站接收到报文时，首先根据报文携带的业务流标识确定该业务流标识对应的第一转发策略，再根据该第一转发策略对该报文进行转发，处理功能实体、转发器和路由功能实体同理，因此，第一转发策略、第二转发策略及处理策略中均包含业务流标识。
实现方式四
该实现方式可以基于图17或图19所示的网络系统的架构下，其中，当基于图17所示的网络系统的架构时，网络系统中包括一个控制器，步骤601至步骤603的执行主体均为控制器；当基于图19所示的网络系统的架构时，网络系统中包括路由控制器和至少一个处理控制器，步骤601的执行主体为上述至少一个处理控制器，步骤602和步骤603的执行主体为路由控制器。
如图6所示，上述方法在具体实现时包括：
601、向M个处理功能实体中的每个处理功能实体发送对应的 处理策略。
具体的，可以根据业务流标识生成每个处理功能实体对应的处理策略，一个处理功能实体对应一个处理策略，向一个处理功能实体发送的处理策略用于该处理功能实体根据该处理策略对接收到的报文进行处理。
602、向路由功能实体发送第一转发策略。
具体的，当第一节点为基站时，第一转发策略可以根据业务流标识和M个处理功能实体的标识生成，当第一节点为路由功能实体时，第一转发策略可以根据业务流标识、M个处理功能实体的标识和第二节点的标识生成。基于图17或图19所示的网络系统的架构，以第一节点为路由功能实体，第二节点为基站(假设基站的标识为A)为例，报文在2个处理功能实体中的处理顺序为：标识为2的处理功能实体2—标识为1的处理功能实体1。该情况下，针对上述业务流标识的第一转发策略的一种形式可以为：2—1—A。图17和图19中的虚线指示了该报文的路径。
603、向第一节点发送第二转发策略。
第二转发策略可以根据业务流标识和路由功能实体的标识生成。具体关于业务流标识的描述可以参见实现方式一。路由功能实体的标识可以为路由功能实体的IP地址、MAC地址、连接端口号或隧道标识等。
需要说明的是，当基于图17(图19)所示的网络系统的架构时，控制器(路由控制器)在确定业务流标识之后，可以根据业务流标识确定携带该业务流标识的报文对应的处理逻辑，即所述报文经过的处理功能实体。
其中，本发明实施例中对步骤601、步骤602和步骤603的执行顺序不做具体限定。
604、第一节点接收第二转发策略；当第一节点接收到报文时， 根据该第二转发策略将该报文转发至路由功能实体。
605、M个处理功能实体中的每个处理功能实体接收对应的处理策略；当一个处理功能实体接收到路由功能实体发送的报文时，根据自身对应的处理策略对接收到的路由功能实体发送的报文进行处理后转发至路由功能实体。
具体的，每个处理功能实体对应的下一节点可以预配置为路由功能实体，或者，每个处理功能实体对应的处理策略中可以添加路由功能实体的标识，添加的该标识用于告知该处理功能实体对应的下一节点。
606、路由功能实体接收第一转发策略，并根据所述第一转发策略对接收到的所述报文进行转发，以使得所述报文经过M个处理功能实体依次处理后到达所述第二节点。
具体的，路由功能实体根据第一转发策略具体执行以下动作：当路由功能实体接收到第三节点发送的报文时，将该报文转发至第四节点。其中，当所述第三节点为所述基站时，所述第四节点为第1处理功能实体，当M≥2、且所述第三节点为第m处理功能实体时，所述第四节点为第m+1处理功能实体；或者，当所述第三节点为外部网络时，所述第四节点为第1处理功能实体，当M≥2、且所述第三节点为第m处理功能实体时，所述第四节点为第m+1处理功能实体，当所述第三节点为第M处理功能实体时，所述第四节点为所述基站；所述报文在所述M个处理功能实体中的处理顺序依次为所述第1处理功能实体至所述第M处理功能实体，1≤m≤M-1，M≤N，m、M均为整数。
需要说明的是，当第一节点为基站时，基站需要将报文转发至路由功能实体，以便路由功能实体根据第一转发策略对报文进行转发，因此，路由控制器需要向基站发送第二转发策略；而当第一节点为路由功能实体时，外部网络发送的报文直接到达路由功能实体， 因此路由功能实体可以直接根据第一转发策略对报文进行转发。因此，当第一节点为路由功能实体时，步骤603和步骤604可以省略。
基于图17(图19)中的虚线指示的报文的路径，当报文到达路由功能实体时，路由功能实体根据第一转发策略确定报文经过的节点依次为：标识为2的节点(即处理功能实体2)—标识为1的节点(即处理功能实体1)—标识为A的节点(即基站)，因此，路由功能实体根据第一转发策略将报文转发至处理功能实体2，处理功能实体2根据对应的处理策略将接收到的路由功能实体发送的报文进行处理后转发至路由功能实体；路由功能实体接收到处理功能实体2发送的报文后，根据第一转发策略将该报文转发至处理功能实体1，处理功能实体1根据对应的处理策略将接收到的路由功能实体发送的报文进行处理后转发至路由功能实体；路由功能实体接收到处理功能实体1发送的报文后，将该报文转发至基站。
具体的，当第二节点为基站时，基站接收到路由功能实体发送的报文时，将该报文转发至UE；当第二节点为路由功能实体时，路由功能实体接收到M个处理功能实体中的最后一个处理报文的处理功能发送的报文时，将该报文转发至外部网络。
需要说明的是，当基于图17所示的网络系统的架构时，第一转发策略、第二转发策略和处理策略均由控制器生成。
当基于图19所示的网络系统的架构时，当网络系统中只有一个处理控制器时，步骤601包括：处理控制器向N个处理功能实体中的M个处理功能实体中的每个处理功能实体发送对应的处理策略。当网络系统中有N个处理控制器时，步骤601包括：N个处理控制器中的M个处理控制器向对应的N个处理功能实体中的M个处理功能实体中的每个处理功能实体发送对应的处理策略，其中，一个处理控制器对应一个处理功能实体。相应的，第一转发策略和第二转发策略由路由控制器生成，N个处理功能实体对应的处理策略由 至少一个处理控制器生成。
在一种可实现的方式中，第一转发策略和第二转发策略也可以相同，该情况下，第一转发策略和第二转发策略可以为根据报文转发的整条路径中的各个节点的标识生成的转发策略。
在实现方式四中，实现方式三中的转发器的功能集成在路由功能实体，相比实现方式一和实现方式二，在不增加转发器的情况下，使得控制器或路由控制器不需要再向每个处理功能实体发送第二转发策略，从而减少了控制信令的条数。
需要说明的是，路由功能实体中可能包含多个业务流标识对应的多个第一转发策略，一个业务流标识对应一个第一转发策略，当路由功能实体接收到报文时，首先根据报文携带的业务流标识确定该业务流标识对应的第一转发策略，再根据该第一转发策略对该报文进行转发，处理功能实体和基站同理，因此，第一转发策略、第二转发策略及处理策略中均包含业务流标识。
需要强调的是，在上述四种实现方式的描述过程中，均以上述转发策略及处理策略针对上行报文或下行报文为例对本发明提供的方法进行阐述，事实上，在具体实现时，在确定业务流标识后，可以根据下行预配置策略生成针对下行报文的转发策略及处理策略，根据上行预配置策略生成针对上行报文的转发策略及处理策略，并向相应的设备下发这些策略。
实施例1
该实施例以UE发送的报文(即上行报文)需要经过处理功能实体1和处理功能实体2处理以及UE在发送报文前发送业务请求为例对上述实现方式一及实现方式二进行示例性说明。该实施例中的相关解释可以参见上述实现方式一及实现方式二中的描述。
该实施例中提供的方法可以应用于图17或图19所示的网络系统的架构下，其中，当基于图17所示的网络系统的架构时，步骤701 至步骤704的执行主体均为控制器；当基于图19所示的网络系统的架构时，步骤701的执行主体为路由控制器和处理控制器(该实施例中以网络系统包括一个处理控制器和路由控制器为例)，步骤702和步骤703的执行主体为路由控制器，步骤704的执行主体为处理控制器。
如图7所示，上述方法在具体实现时包括：
701、接收UE发送的业务请求，并根据该业务请求确定业务流标识1。
具体的，业务请求中包括业务流标识1。业务流标识1可以为UE的IP地址或业务流的IP五元组等。
702、根据业务流标识1和处理功能实体1的标识生成第一转发策略，并向基站发送该第一转发策略。
处理功能实体的标识可以为处理功能实体的IP地址、MAC地址、连接端口号或隧道标识等。处理功能实体1为第一个处理携带业务流标识1的报文的处理功能实体。
703、根据业务流标识1和处理功能实体2的标识生成处理功能实体1对应的第二转发策略1；根据业务流标识1和路由功能实体的标识生成处理功能实体2对应的第二转发策略2；并向处理功能实体1发送第二转发策略1，向处理功能实体2发送第二转发策略2。
示例性的，假设路由功能实体的标识为B，处理功能实体1的标识为1，处理功能实体2的标识为2，则第二转发策略1中包含业务流标识1和标识2，第二转发策略2中包含业务流标识1和标识B。
