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。
请参阅图1，图1是本发明实施例提供的一种系统架构示意图，如图1所示，包括：一个或者多个UE11、演进的通用陆基无线接入网(Evolved Universal Terrestrial Radio Access Network，E-UTRAN)12、移动管理实体(Mobile Managenment Entity，MME)13、归属用户服务器(Home Subscriber Server，HSS)14、网关用户面实体(GateWay-U，GW-U)15、网关控制面实体(GateWay-C，GW-C)16、策略和计费规则功能实体(Policy charging and rules function，PCRF)17和运营商IP网络服务18，其中，运营商IP网络服务18可以是IP多媒体子系统(IP Multimedia Subsystem，IMS)或者分组业务子系统PSS等。其中，如图1所示，UE1可以通过LTE-Uu接口接入E-UTRAN12，E-UTRAN12可以通过S1-MME接口连接MME13，以及E-UTRAN12可以通过S1-U接口连接GW-U15，MME13可以通过S6a接口连接HSS14，以及MME13可以通过S11接口连接GW-C16，GW-C16可以通过S18接口连接GW-U15，且GW-C16可以通过Gx接口连接PCRF17，PCRF17可以通过Rx接口连接运营商IP网络服务18，GW-U15还可以与UE1连接。另外，上述GW-U15可以是实现网关用户面功能的实体，例如：进行信令报文的转发处理，且GW-U15可以是分布式的网关实体，例如：如图1所示，GW-U15可以包括服务网关用户面实体(Serving GateWay-U，SGW-U)、分组数据网络网关用户面实体(Packet Data Network GateWay-U，PGW-U)、不可信的非3GPP网关Untrusted Non-3GPP GW-U和可信的非3GPP网关用户面实体Trusted Non-3GPP GW-U中的一个或者多个，且GW-U15包括的实体之间的连接关系可以如图1所示。另外，上述GW-C16可以实现网关控制面的功能，例如：对 信令报文进行响应。另外，GW-C16还可以融合各类形态网关的信令报文处理能力，例如：通过本地配置或者操作维护(Operation Maintenance，OM)配置GW-C16融合各类形态网关的信令报文处理能力。在上述网络构架中可以通过GW-U15实现对信令报文的转发，通过GW-C16实现对信令报文的响应，从而当网络需要支持新协议的信令报文时，GW-U15只需要获取新协议的信令报文的处理信息，就可以实现对新协议的信令报文进行转发处理，从而不需要额外部署网关，以节约网络成本。
需要说明的是，如图1所示的网络架构仅是本发明实施例中可应用的网络架构中的举例，本发明实施例中可以应用于任何需要对信令报文进行处理的网络架构，例如：EPC网络。
请参阅图2，图2是本发明实施例提供的一种信令报文处理方法的流程示意图，如图2所示，包括以下步骤：
201、网关用户面实体获取目标信令报文的处理信息。
其中，上述处理信息包括转发对象、所述网关用户面实体接收所述目标信令报文的类型信息和所述网关用户面实体发送所述目标信令报文的目的地址三者中的至少一项。即上述处理信息包括转发对象、所述网关用户面实体接收所述目标信令报文的类型信息和所述网关用户面实体发送所述目标信令报文的目的地址这三者中一项或者多项。
本实施例中，通过上述处理信息可以表示上述目标信令报文的处理流程或者上述处理信息可以表示网关用户面实体对上述目标信令报文处理的动作和处理的参数。另外，步骤201可以是接收网关控制面实体生成并转发的上述处理信息，或者网关用户面实体配置上述处理信息。
另外，本实施例中，上述目标信令报文可以网络中可传输的任何信令报文，例如上述目标信令报文可以是DHCP信令报文、代理移动IP(Proxy Mobile IP，PMIP)信令报文、IKE信令报文、EAP信令报文、PPP信令报文或者L2TP信令报文或者GTP信令报文等。

本实施例中上述按照所述处理信息对所述目标信令报文进行处理可以是按照所述处理信息对应的处理流程对所述目标信令报文进行转发处理，或者按照处理信息包括的处理动作和处理参数对目标信令报文进行处理。
另外，如图1所示，本实施例中网关用户面实体与网关控制面实体之间可以通过S18接口进行连接，其中，S18接口可以采用GPRS隧道协议(GPRS Tunneling Protocol，GTP)作为传输协议。当然，本实施例中，网关用户面实体与网关控制面实体可以使用其他协议的接口进行连接，例如：使用传输控制协议(Transmission Control Protocol，TCP)或者用户数据报协议(User Datagram Protocol，UDP)等传输协议的接口进行连接。
本实施例中，网关用户面实体获取目标信令报文的处理信息；所述网关用户面实体接收所述目标信令报文，并按照所述处理信息对所述目标信令报文进行处理。这样可以实现网关用户面实体根据获取的处理信息灵活对信令报文进行处理，从而当网络需要支持新协议时，网关用户面实体只需要获取新协议的信令报文的处理信息，就可以实现对新协议的信令报文进行处理，从而不需要额外部署网关，以节约网络成本。
请参阅图3，图3是本发明实施例提供的另一种信令报文处理方法的流程示意图，如图3所示，包括以下步骤：
301、网关用户面实体获取目标信令报文的处理信息，其中，上述处理信息包括如下至少一项：
网关用户面实体接收所述目标信令报文的类型信息和所述网关用户面实体发送所述目标信令报文的目的地址。
其中，上述类型信息表示需要接收什么类型信息的信令报文，另外，上述目的地址可以是表示网关用户面实体需要将目标信令报文发送的目的地址。
本实施例中，步骤301可以包括：
网关用户面实体接收所述网关控制面实体发送的处理信息。
该实施方式中，上述处理信息可以是由上述网关控制面实体生成的。例如：网关控制面实体可以通过OM配置生成目标信令报文的处理信息；或者网关控制面实体可以根据本地用户配置数据生成目标信令报文的处理信息。
本实施例中，步骤301可以包括：
网关用户面实体配置所述处理信息。例如：网关用户面实体通过OM配置生成目标信令报文的处理信息；或者网关用户面实体可以根据本地用户配置数据生成目标信令报文的处理信息。

本实施例中，当获取到上述处理信息后，就可以确定接收所述目标信令报文的类型信息或者所述网关用户面实体发送所述目标信令报文的目的地址，从而可以对按照该类型信息和目的地址接收目标信令报文和发送目标信令报文。
例如：步骤302可以包括：
网关用户面实体按照所述处理信息包括的所述类型信息接收网络实体发送的与所述类型信息匹配的所述目标信令报文，并按照所述处理信息包括的所述动作对所述目标信令报文进行转发处理，其中，所述网络实体包括网关控制面实体或者外部信令报文发送实体或者用户设备。
其中，上述外部信令报文发送实体可以包括网元设备，例如：SGSN网元。
其中，由于上述类型信息可以得知网关用户面实体当前需要接收到报文的类型，即得到上述目标信令报文的类型，这样当网络实体发送的上述目标信令报文时，就可以按照该类型信息获取到该目标信令报文。另外，上述处理信息还可以包括处理的动作，从而网关用户面实体可以直接根据该动作对目标信令报文进行处理，例如：发送、加封装或者解封装等处理。
另外，上述处理信息还可以包括网关用户面实体发送所述目标信令报文的目的地址，这样就可以直接根据处理信息包括的处理动作和目的地址，并目标信令报文发送给目的地址对应的设备。由于发送目标信令报文是处理信息中的目的地址，从而相比目标信令报文中携带目的地址，本实施例可以更加灵活转 发目标信令报文。
本实施例中，上述网关用户面实体按照所述处理信息包括的所述类型信息接收网络实体发送的与所述类型信息匹配的所述目标信令报文，并按照所述处理信息包括的所述动作对所述目标信令报文进行转发处理的步骤，可以包括：

另外，上述方法还可以包括如下步骤：
网关用户面实体向所述网关控制面实体发送所述网关控制面实体接收的信令报文为DHCP信令类型报文的指示消息。
这样网关控制面实体就可以通过该指示消息确认接收的信令报文为DHCP信令类型报文，例如：通过隧道报文发送时，那么，网关控制面实体就可以通过该指示消息确认接收的隧道报文携带的报文为DHCP信令类型报文，这样可以使网关控制面实体快捷地识别出DHCP信令报文。当然，本实施例中，不发送上述指示信息也是可以的，这样网关控制面实体可以通过对上述隧 道报文进行解封装，以确认解封装获取的报文为DHCP信令报文。
另外，上述方法还可以包括如下步骤：
网关用户面实体接收所述网关控制面实体发送的针对所述DHCP响应报文进行的隧道报文加封装的操作指示，以及按照所述处理信息包括的接收报文的动作接收所述网关控制面实体发送的所述DHCP响应报文，并按照所述操作指示将所述DHCP响应报文封装成隧道报文给所述用户设备。

402、网关用户面实体向网关控制面实体转发该DHCP Discover报文；
403、网关控制面实体向网关用户面实体发送DHCP OFFER报文，其中，该DHCP OFFER报文是网关控制面实体对DHCP Discover报文进行响应所产生的响应报文；

这样通过该操作指示可以使网关用户面实体根据操作指示灵活转发报文。
该实施方式中，网关用户面实体可以通过GTP-C消息向网关控制面实体发送上述IKE信令报文，即将该IKE信令报文作为消息的中信元转发给网关控制面实体。或者网关用户面实体可以通过GTP-U隧道将上述IKE信令报文发送给网关控制面实体，例如：将IKE信令报文作为数据报文，封装GTP-U头通过GTP-U隧道发送给网关控制面实体。
