图1A为一种移动通信网络的逻辑架构图，如图1A所示，该逻辑架构包括用户设备11、接入节点12、控制面节点13和用户面节点14。其中，用户设备11可以通过本地的接入节点12接入该移动通信网络，控制面节点13负责用户设备11的连接管理、安全认证、移动性管理和位置管理，用户面节点14负责用户设备11业务数据的转发。在目前提供的一种本地网络的连接方法中，移动通信网络运营商为每一个本地网络覆盖的区域规划特定的位置区域标识，且上述控制面节点13为移动运营商为对应本地网络覆盖的位置区域部署的专有的控制面节点，用于建立到对应本地网络的连接。当用户设备11进入到该特定的位置区域时，可以向该位置区域的接入节点12发送接入请求，接入节点12接收到该接入请求，会向该位置区域专有的控制面节点13转发该接入请求，该专有的控制面节点13接收到该接入请求后，即自动建立该用户设备11到该位置区域的本地网络的连接。
在实现本发明的过程中，发明人发现相关技术至少存在以下问题：
上述方法中，当用户设备进入某一位置区域时，由专有的控制面节点自动建立该用户设备到本地网络的连接，也即是由控制面节点默认连接，但是实际应用中，默认连接的本地网络可能不是用户想要接入的本地网络，或者质量较高的本地网络，因此上述方法的灵活性较低，具有一定的局限性。同时，上述方法需要为每一个本地网络规划特定的位置区域标识，并部署专有的控制面节点，因此部署成本过高。
发明内容
为了解决现有技术的问题，本发明实施例提供了一种本地网络的连接方法、装置及系统。所述技术方案如下：
第一方面，提供了一种本地网络的连接方法，应用于控制面节点中，所述方法包括：
接收接入节点发送的位置区域标识，所述位置区域标识为所述接入节点在接收到用户设 备发送的接入请求时发送，用于指示所述用户设备当前所处的位置区域；
根据所述位置区域标识，确定至少一个本地网络标识，并将所述至少一个本地网络标识发送给所述用户设备；
接收所述用户设备发送的建立连接请求，所述建立连接请求携带所述用户设备基于所述至少一个本地网络标识选择的第一本地网络标识；
根据所述第一本地网络标识，建立所述用户设备到第一本地网络的连接。
本发明实施例中，用户设备在当前所处的位置区域向接入节点发送接入请求时，接入节点可以根据该接入请求，向控制面节点发送指示该用户设备所处位置区域的位置区域标识。控制面节点则可以根据该位置区域标识确定至少一个本地网络标识，并将该至少一个本地网络标识发送至用户设备，以供用户设备进行选择。之后，当接收到用户设备发送的建立连接请求，且该建立连接请求携带该用户设备基于该至少一个本地网络标识选择的第一本地网络标识时，即可建立该用户设备到第一本地网络的连接。
由于当用户设备进入某一位置区域时，控制面节点可以将该位置区域内的至少一个本地网络标识发送至该用户设备，因此用户可以通过用户设备自主选择需要接入的本地网络，也即是，自主选择想要接入的本地网络或质量较高的本地网络，从而提高了本地网络的连接效果和灵活性，扩展了本地网络的连接方式。同时，移动通信网络运营商也无需为每一个本地网络都规划特定的位置区域标识，部署专有的控制面节点，可以将多个本地网络规划到同一个位置区域内，控制面节点可以同时服务多个相邻的位置区域，降低了部署成本。
在另一实施例中，所述根据所述位置区域标识，确定至少一个本地网络标识，包括：
从存储的位置区域列表中获取所述位置区域标识对应的本地网络标识，所述位置区域列表中存储多个位置区域标识和对应的本地网络标识。

本发明实施例中，控制面节点还可以根据该用户设备的本地网络接入指示信息和位置区域列表共同确定允许该用户设备接入的至少一个本地网络。由于该本地网络接入指示信息用于指示该用户设备是否允许接入本地网络，也即是用户是否允许所使用的用户设备接入本地网络，因此可以结合用户的意愿将用户设备连接至本地网络，从而进一步提高了本地网络连接的灵活性和连接效果。
在另一实施例中，所述根据所述位置区域标识，确定至少一个本地网络标识，包括：
从存储的位置区域列表中获取所述位置区域标识对应的本地网络标识；
获取所述用户设备的本地网络签约信息，所述本地网络签约信息包括本地网络标识信息， 所述本地网络标识信息为允许所述用户设备接入的本地网络标识；
根据所述位置区域标识对应的本地网络标识和所述本地网络标识信息，确定所述至少一个本地网络标识。
本发明实施例中，控制面节点还可以获取用户设备的本地网络签约信息，该本地网络签约信息包括本地网络标识信息，由于该本地网络标识信息用于指示允许该用户设备接入的本地网络标识，也即是该用户设备预先签约的本地网络。因此可以结合该位置区域标识对应的本地网络标识和该用户设备签约的本地网络标识，综合确定允许该用户设备接入的至少一个本地网络，从而扩展了对本地网络的连接管理方式，进一步提高了连接的准确性和连接效果。
在另一实施例中，所述根据所述位置区域标识，确定至少一个本地网络标识，包括：
从存储的位置区域列表中获取所述位置区域标识对应的本地网络标识；
获取所述用户设备的本地网络签约信息，所述本地网络签约信息包括网络能力指示信息，所述网络能力指示信息用于指示是否允许所述用户设备接入本地网络；
当所述网络能力指示信息指示允许所述用户设备接入本地网络时，将所述位置区域标识对应的本地网络标识确定为所述至少一个本地网络标识。
本发明实施例中，用户设备的本地网络签约信息还可以包括网络能力指示信息，该网络能力指示信息用于指示是否允许该用户设备接入本地网络，也即是，该用户设备是否预先通过签约开通了接入本地网络的功能。因此该控制面节点还可以结合本地网络签约信息中的网络能力指示信息将该用户设备接入本地网络，从而扩展了对本地网络的连接管理方式，进一步提高了连接的准确性和连接效果。
在另一实施例中，所述根据所述位置区域标识，确定至少一个本地网络标识，包括：
从存储的位置区域标识列表中获取所述位置区域标识对应的本地网络标识；
获取运营商策略，所述运营商策略包括本地网络标识信息，所述本地网络标识信息为允许所述用户设备接入的本地网络标识；
根据所述位置区域标识对应的本地网络标识和所述本地网络标识信息，确定所述至少一个本地网络标识。

本发明实施例中，还可以通过该控制面节点所属移动通信网络运营商的运营商策略对用户设备接入的本地网络进行设置和管理，其中，该运营商策略也可以包括本地网络标识信息或者网络能力指示信息，从而进一步扩展了对本地网络的连接管理方式，提高了连接的准确性和连接效果。
在另一实施例中，所述接入请求包括位置区域更新请求或附着请求，所述位置区域更新请求由所述用户设备在所处的位置区域发生变化时发送，所述附着请求由所述用户设备在设备开启时发送。
本发明实施例中，接入节点可以在接收到用户设备发送的位置区域更新请求时，向控制面 节点发送位置区域标识，以将该用户设备接入移动后所处位置区域的本地网络。也可以在接收到用户设备的附着请求时，向控制面节点发送位置区域标识，以将该用户设备接入设备开启时所处的位置区域的本地网络。通过在接收到用户设备的位置区域更新请求或附着请求时，发送位置区域标识，实现了利用移动通信网络将用户设备接入本地网络。
在另一实施例中，所述根据所述第一本地网络标识，建立所述用户设备到第一本地网络的连接之前，还包括：
判断所述至少一个本地网络标识是否包括所述第一本地网络标识；
当所述至少一个本地网络标识包括所述第一本地网络标识时，根据所述第一本地网络标识，建立所述用户设备到第一本地网络的连接。
本发明实施例中，控制面节点接收到用户设备发送的第一网络标识之后，还可以对该第一网络标识进行核查，也即是，判断该第一网络标识是否包括在该控制面节点向该用户设备发送的至少一个本地网络标识中，核查通过时才建立连接，从而进一步提高了准确性。
在另一实施例中，本地网络标识为本地网络对应的接入点名称、本地网络的网络名称或者本地网络的企业名称。

本发明实施例提供的技术方案带来的有益效果是：
本发明实施例中，当用户设备进入某一位置区域并向接入节点发送接入请求时，接入节点可以向控制面节点发送指示该用户设备当前所处的位置区域的位置区域标识。由于控制面 节点可以根据该位置区域标识，确定至少一个本地网络标识，并将该至少一个本地网络标识发送给用户设备以供用户设备进行选择，因此用户可以通过该用户设备自主选择需要接入的本地网络，也即是，自主选择想要接入的本地网络或质量较高的本地网络，从而提高了本地网络的连接效果和灵活性，扩展了本地网络的连接方式。同时，移动通信网络运营商也无需为每一个本地网络都规划特定的位置区域标识，部署专有的控制面节点，可以将多个本地网络规划到同一个位置区域内，控制面节点可以同时服务多个相邻的位置区域，降低了部署成本。

参见图1A，用户面节点14可以包括公网的用户面节点和本地网络的用户面节点，其中，公网的用户面节点用于提供外部的报文数据网络的访问，本地网络的用户面节点用于提供本地网络的访问。例如，对于某一企业园区来说，可以在园区或离园区较近的位置部署本地网络的用户面节点，用以提供园区企业网的访问。参考图1B，在该园区范围外，用户设备可以通过公网的用户面节点141访问外部的报文数据网络，在该园区范围内，用户设备可以通过本地网络的用户面节点142访问该园区的园区企业网。
实际应用中，上述移动通信网络可以为下一代通信网络、EPS(Evolved Packet System，演进的分组系统)网络、eLTE(evolved Long Term Evolution，演进的长期演进系统)网络、 或者2G/3G(The 2nd Generation/The 3rd Generation，第二代/第三代)网络等。
接下来将结合附图，对上述四种移动通信网络作进一步地详细描述：

3)eLTE网络
当该移动通信网络为eLTE网络时，针对图1A所示的逻辑架构图，接入节点12为接入网，控制面节点13为移动管理实体，用户面节点14为用户面的服务网关和用户面的数据网关。
需要说明的是，eLTE网络为EPS网络的增强网络，与EPS网络的区别在于，eLTE网络将服务网关拆分成了控制面的服务网关和用户面的服务网关，并将数据网关拆分成了控制面的数据网关和用户面的数据网关。
图1E是本发明实施例提供的一种eLTE网络的逻辑架构图。如图1E所示，该eLTE网络的逻辑架构包括用户设备41、接入网42、移动管理实体43、用户面的服务网关441和用户面的数据网关442、控制面的服务网关451和控制面的数据网关452。

其中，该2G/3G网络可以为GSM(Global System for Mobile Communication，全球移动通信系统)网络，或者GPRS(General Packet Radio Service，通用分组无线服务技术)网络，或者UMTS(Universal Mobile Telecommunications System，通用移动通信系统)网络等。
本发明提供的方法的执行主体为图1A的控制面节点13，由上述描述可知，该控制面节点13可以为控制面功能网元、移动管理实体(Mobility Management Entity，MME)、GPRS服务支撑节点(Serving GPRS Support Node，SGSN)等。
而且，本发明实施例中，可以将多个本地网络规划到同一个位置区域内，控制面节点13可以同时服务多个相邻的位置区域。
具体地，参见图1G，上述控制面节点可以包括通信总线131、存储器132、发射机133、接收机134和处理器135，且存储器132、发射机133、接收机134和处理器135可以通过通信总线131互通。
其中，发射机133和接收机134用于与其他网络设备通信，如该控制面节点可以通过接收机134与接入节点进行通信，接收接入节点发送的位置区域标识；或者通过发射机133和接收机134与用户设备进行通信，通过发射机133向用户设备发送本地网络标识，通过接收机134接受用户设备发送的本地网络标识。
其中，存储器132，用于存储程序；处理器135，用于调用存储器132中存储的程序，实现下述方法步骤：
接收接入节点发送的位置区域标识，该位置区域标识为该接入节点在接收到用户设备发送的接入请求时发送，用于指示该用户设备当前所处的位置区域；
根据该位置区域标识，确定至少一个本地网络标识，并将该至少一个本地网络标识发送给该用户设备；
接收该用户设备发送的建立连接请求，该建立连接请求携带该用户设备基于该至少一个本地网络标识选择的第一本地网络标识；
根据该第一本地网络标识，建立该用户设备到第一本地网络的连接。
需要说明的是，上述处理器135可能是一种集成电路芯片，具有信号的处理能力。在实现过程中，上述步骤可以通过处理器中的硬件的集成逻辑电路或者软件形式的指令完成。这些指令可以通过其中的处理器以配合实现及控制。上述处理器还可以是通用处理器、数字信号处理器(英文：digital signal processor，简称：DSP)、专用集成电路(英文：application-specific integrated circuit，简称：ASIC)、现成可编程门阵列(英文：field programmable gate array，简称：FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。

另外，发射机133和接收机134可以为单独的两个硬件，也可以作为一个整体集成在该控制面节点中，如该发射机133和接收机134可以集成为一个收发机。
另外，该控制面节点还可以包括通信接口，用于支持该控制面节点与其他网络设备的通信。通信总线131除包括数据总线之外，还包括电源总线、控制总线和状态信号总线。但是为了清楚说明，在图1C中将各种总线都标为通信总线131。
图2是本发明实施例提供的一种本地网络的连接方法流程图，该方法的交互主体为用户设备、接入节点和控制面节点，参见图2，该方法包括：
步骤201：用户设备向接入节点发送接入请求。
其中，接入节点为该用户设备当前所处位置区域对应的接入节点。接入请求包括位置区域更新请求或附着请求，位置区域更新请求由该用户设备在所处的位置区域发生变化时发送，附着请求由该用户设备在设备开启时发送。接入节点需要将该接入请求消息转发给控制面节点。
例如，由于部署本地网络的企业园区和该企业园区外的区域处于不同的位置区域，因此当用户设备从该企业园区外移动到该企业园区内，由于位置区域发生变化，从而会促使该用户设备发起位置区域更新流程，而在该流程中会先向接入节点发送位置区域更新请求。
步骤202：接入节点接收到用户设备发送的接入请求时，确定该用户设备当前所处的位置区域，并向控制面节点发送位置区域标识。
其中，该位置区域标识用于指示该用户设备当前所处的位置区域。
本发明实施例中，接入节点可以将所服务的地理范围划分为不同的位置区域，并为每个位置区域设置对应的位置区域标识，该位置区域标识用于唯一指示该位置区域。具体地，该位置区域标识可以为该位置区域的名称、编号等，本发明实施例对此不做限定。
当接入节点接收到用户设备发送的接入请求时，可以确定该用户设备当前所处位置的位置区域标识，以向控制面节点发送该位置区域标识。
其中，针对EPS网络、eLTE网络和2G/3G网络，上述用户设备发送的位置区域更新请求可以为路由区域更新请求或者跟踪区域更新请求，相应地，接入节点发送的位置区域标识可以为路由区域标识(Routing area identity，RAI)或者跟踪区域标识(Tracking areaidentity，TAI)。
同时，接入节点还将收到的接入请求转发给控制面节点。
步骤203：控制面节点接收接入节点发送的位置区域标识，根据该位置区域标识，确定至少一个本地网络标识，并将该至少一个本地网络标识发送给该用户设备。
其中，本地网络标识用于唯一指示一个本地网络，可以为本地网络对应的接入点名称(Access Point Name，APN)、本地网络的网络名称或者本地网络的企业名称等，本发明实施例对此不做限定。而且可以通过字母、数字和特殊字符等的组合来标识该本地网络标识。例如，该本地网络标识可以为enterprise01，enterprise01.mnc012.mcc345.gprs，enterprise01.mnc034.mcc567.org等。
本发明实施例中，根据该位置区域标识，确定至少一个本地网络标识，可以包括以下几种可能的实现方式：
第一种方式：从存储的位置区域列表中获取该位置区域标识对应的本地网络标识，该位置区域列表中存储多个位置区域标识和对应的本地网络标识；将该位置区域标识对应的本地网络标识确定为该至少一个本地网络标识。
需要说明的是，本发明实施例中，可以将多个本地网络规划到同一个位置区域内，一个控制面节点可以同时服务多个相邻的位置区域，因此每个位置区域内可以有一个或者多个本地网络，对应一个或者多个本地网络标识，不同的位置区域可以对应不同的一个或者多个本地网络。而且，本发明实施例中，可以将不同位置区域标识和对应的本地网络标识预先存储在一个位置区域列表中，以便根据该位置区域列表匹配某个位置区域标识对应的本地网络标识。
其中，控制面节点可以从本地存储的位置区域列表中获取对应的本地网络标识，也可以将位置区域标识发送至其他网元，从其他网元存储的位置区域列表中获取对应的本地网络标识，本发明实施例对此不做限定。
也即是，控制面节点可以预先存储位置区域列表，例如，可以通过操作维护端(Operation and Maintenance，O&M)预先将位置区域列表配置在控制面节点上，或者，从其他网元中获取位置区域列表并存储本地；当然，控制面节点也可以不存储位置区域列表，当控制面节点接收到位置区域标识时，可以将该位置区域标识发送至其他功能网元，由其他功能网元从位置区域列表中获取对应的本地网络标识，并将对应的本地网络标识返回至该控制面节点。
其中，上述其他功能网元可以为签约数据中心、家乡用户寄存器、策略功能网元等，本发明实施例对此不做限定。
第二种方式：从存储的位置区域列表中获取该位置区域标识对应的本地网络标识之后，结合该用户设备的本地网络接入指示信息、本地网络签约信息和运营商策略中的至少一个，确定该至少一个本地网络标识。
具体地，可以包括以下几种可能的实现形式：
1、结合位置区域列表和该用户设备的本地网络接入指示信息，确定该至少一个本地网络标识。
具体地，该控制面节点可以从存储的位置区域列表中获取该位置区域标识对应的本地网络标识；接收该用户设备通过该接入节点发送的接入请求，该接入请求中携带本地网络接入指示信息，该本地网络接入指示信息用于指示该用户设备是否允许接入本地网络；当该本地网络接入指示信息指示该用户设备允许接入本地网络时，将该位置区域标识对应的本地网络标识确定为该至少一个本地网络标识。
另外，当该本地网络接入指示信息指示该用户设备不允许接入本地网络时，该控制面节点还可以不再确定本地网络标识，进而也不向该用户设备发送任何本地网络标识。
其中，接入请求中携带的本地网络接入指示信息可以包括以下几种形式：
1)接入请求可以携带一种类型的指示信息，用于指示用户设备不允许接入本地网络。例如，若接入请求中携带该指示信息，则表示该用户设备不允许接入本地网络；若接入请求中未携带该指示信息，则表示该用户设备允许接入本地网络。
2)接入请求可以携带一种类型的指示信息，用于指示用户设备允许接入本地网络。例如，若接入请求中携带该指示信息，则表示该用户设备允许接入本地网络；若接入请求中未携带该指示信息，则表示该用户设备不允许接入本地网络。
3)接入请求可以携带两种类型的指示信息，第一指示信息用于指示用户设备允许接入本地网络，第二指示信息用于指示用户设备不允许接入本地网络。例如，若接入请求中携带第一指示信息，则表示该用户设备允许接入本地网络；若接入请求中携带第二指示信息，则表 示该用户设备不允许接入本地网络。
需要说明的是，用户设备的本地网络接入指示信息可以指示用户的意愿。实际应用中，可以在用户设备中设置一个同意选项和/或拒绝选项，用于指示用户是否同意所使用的用户设备接入本地网络。当检测到对同意选项的触发操作时，即可在接入请求中携带指示该用户设备允许接入本地网络的本地网络接入指示信息，当检测到对拒绝选项的触发操作时，即可在接入请求中携带指示该用户设备不允许接入本地网络的本地网络接入指示信息。
2、结合位置区域列表和本地网络签约信息，确定该至少一个本地网络标识。
本发明实施例中，该控制面节点还可以结合本地网络签约信息对允许用户设备接入的本地网络进行管理，从而扩展对本地网络连接的管理方式，提高连接的准确性和连接效率。
其中，用户设备的本地网络签约信息可以包括本地网络标识信息或者网络能力指示信息，本地网络标识信息为允许该用户设备接入的本地网络标识，网络能力指示信息用于指示是否允许该用户设备接入本地网络。
相应地，结合位置区域列表和本地网络签约信息，确定该至少一个本地网络标识，可以包括以下两种实现方式：
1)从存储的位置区域列表中获取该位置区域标识对应的本地网络标识；获取该用户设备的本地网络签约信息，该本地网络签约信息包括本地网络标识信息，该本地网络标识信息为允许该用户设备接入的本地网络标识；根据该位置区域标识对应的本地网络标识和该本地网络标识信息，确定该至少一个本地网络标识。
其中，根据该位置区域标识对应的本地网络标识和该本地网络标识信息，确定该至少一个本地网络标识，也即是，确定该位置区域标识对应的本地网络标识之中，与该本地网络标识信息中包括的允许该用户设备接入的本地网络标识相同的本地网络标识，将上述相同的本地网络标识确定为该至少一个本地网络标识。
这种实现方式下，用户设备可以预先签约一些本地网络，表示移动通信网络运营商允许该用户设备接入这些已签约的本地网络，并将已签约的本地网络标识存储在本地网络签约信息中，作为本地网络标识信息。后续，当从位置区域列表中获取该位置区域标识对应的本地网络标识时，即可确定这些本地网络标识中哪些本地网络标识为预先已签约的本地网络标识，并将这些本地网络标识中已签约的本地网络标识，作为要发送给用户设备的至少一个本地网络。
2)从存储的位置区域列表中获取该位置区域标识对应的本地网络标识；获取该用户设备的本地网络签约信息，该本地网络签约信息包括网络能力指示信息，该网络能力指示信息用于指示是否允许该用户设备接入本地网络；当该网络能力指示信息指示允许该用户设备接入本地网络时，将该位置区域标识对应的本地网络标识确定为该至少一个本地网络标识。
另外，当该网络能力指示信息指示不允许该用户设备接入本地网络时，该控制面节点还可以不再确定本地网络标识，进而也不向该用户设备发送任何本地网络标识。
相比于上述方式1)，方式2)可以针对一个用户设备对所有本地网络统一进行签约，而非对个别本地网络进行签约，签约后该用户设备即可拥有接入所有本地网络的能力，这个能力可以用网络能力指示信息表示。因此，方式2)的管理方式更加简便，从而减小了控制面节点的管理负担，提高了管理效率。
需要说明的是，上述两种类型的本地网络签约信息均可从数据管理网元中获取，具体地， 对于下一代通信网络，该数据管理网元可以为签约数据中心，对于EPS网络、eLTE网络和2G/3G网络，该数据管理网元可以为家乡用户寄存器(Home Subscriber Server，HSS)或者归属用户寄存器(Home Location Register，HLR)。
3、结合位置区域列表和运营商策略，确定该至少一个本地网络标识。
本发明实施例中，该控制面节点还可以结合所服务的移动通信网络运营商的运营商策略对允许用户设备接入的本地网络进行管理，从而进一步扩展对本地网络连接的管理方式，提高连接的准确性和连接效率。
其中，该运营商策略也可以包括本地网络标识信息或者网络能力指示信息，相应地，结合位置区域列表和运营商策略，确定该至少一个本地网络标识，可以包括以下两种实现方式：
1)从存储的位置区域标识列表中获取该位置区域标识对应的本地网络标识；获取运营商策略，该运营商策略包括本地网络标识信息，该本地网络标识信息为允许该用户设备接入的本地网络标识；根据该位置区域标识对应的本地网络标识和该本地网络标识信息，确定该至少一个本地网络标识。
其中，根据该位置区域标识对应的本地网络标识和该本地网络标识信息，确定该至少一个本地网络标识，也即是，确定该位置区域标识对应的本地网络标识之中，与该本地网络标识信息中包括的允许该用户设备接入的本地网络标识相同的本地网络标识，将上述相同的本地网络标识确定为该至少一个本地网络标识。
2)从存储的位置区域标识列表中获取该位置区域标识对应的本地网络标识；获取该运营商策略，该运营商策略包括网络能力指示信息，该网络能力指示信息用于指示是否允许该用户设备接入本地网络；当该网络能力指示信息指示允许该用户设备接入本地网络时，将该位置区域标识对应的本地网络标识确定为该至少一个本地网络标识。
另外，当该网络能力指示信息指示不允许该用户设备接入本地网络时，该控制面节点还可以不再确定本地网络标识，进而也不向该用户设备发送任何本地网络标识。
4、将上述三种方式中的任意两种进行组合，或者将上述三种方式进行组合，来确定该至少一个本地网络。
例如，当将上述三种方式进行组合时，该控制面节点可以结合位置区域列表、用户设备的本地网络接入指示信息、本地网络签约信息和运营商策略，综合确定该至少一个本地网络标识。
具体地，该控制面节点可以从该位置区域列表中获取该位置区域标识对应的本地网络标识；接收该用户设备通过该接入节点发送的接入请求，该接入请求中携带本地网络接入指示信息；获取该用户设备的本地网络签约信息和运营商策略；根据该位置区域标识对应的本地网络标识、本地网络接入指示信息、本地网络签约信息和运营商策略，综合确定该至少一个本地网络标识。
例如，当该本地网络签约信息包括本地网络标识信息，运营商策略包括网络能力指示信息时，该控制面节点可以在用户设备发送的接入请求中的网络接入指示信息指示该用户设备允许接入本地网络，且运营商策略中的网络能力指示信息指示允许该用户设备接入本地网络时，确定该位置区域标识对应的本地网络标识之中，与该本地网络签约信息的本地网络标识信息中包括的允许该用户设备接入的本地网络标识相同的本地网络标识，并将上述相同的本地网络标识确定为该至少一个本地网络标识。
而当网络接入指示信息指示该用户设备不允许接入本地网络，或者网络能力指示信息指示不允许该用户设备接入本地网络时，则该控制面节点可以不再确定本地网络标识，进而也不向该用户设备发送任何本地网络标识。
再例如，当该本地网络签约信息包括本地网络标识信息，运营商策略也包括本地网络标识信息时，且网络接入指示信息指示该用户设备允许接入本地网络时，则该控制面节点即可确定该位置区域标识对应的本地网络标识、该本地网络签约信息的本地网络标识信息中包括的本地网络标识、该运营商策略的本地网络标识信息中包括的本地网络标识中相同的本地网络标识，并将上述相同的本地网络标识确定为该至少一个本地网络标识。
当然，上述三种方式组合后，也可以有其他实现方式，本发明实施例在此不再一一赘述。
需要说明的一点是，实际应用中，上述本地网络签约信息或者运营商策略中的网络能力指示信息可以有以下几种实现方式：
1)本地网络签约信息或者运营商策略可以携带一种类型的指示信息，用于指示不允许该用户设备接入本地网络。例如，若携带该指示信息，则表示不允许该用户设备接入本地网络；若未携带该指示信息，则表示允许该用户设备接入本地网络。
2)本地网络签约信息或者运营商策略可以携带一种类型的指示信息，用于指示允许该用户设备接入本地网络。例如，若接入请求中携带该指示信息，则表示允许该用户设备接入本地网络；若接入请求中未携带该指示信息，则表示不允许该用户设备接入本地网络。
3)本地网络签约信息或者运营商策略可以携带两种类型的指示信息，第一指示信息用于指示允许该用户设备接入本地网络，第二指示信息用于指示不允许该用户设备接入本地网络。例如，若携带第一指示信息，则表示允许该用户设备接入本地网络；若携带第二指示信息，则表示不允许该用户设备接入本地网络。
需要说明的另一点是，步骤203还可以包括以下步骤2031-2034：
步骤2031:控制面节点接收接入节点发送的位置区域标识。
步骤2032：对该用户设备进行鉴权，确定该用户设备的安全性。
步骤2033：对于位置区域发生变化的用户设备，若该用户设备在位置区域发生变化前已通过指定用户面节点建立网络连接，则通知该指定用户面节点更新连接。
其中，所更新的连接是用户设备到报文数据网络的业务通道，用于转发用户设备和报文数据网络中的应用服务器之间的用户面数据包。
例如，若用户设备在进入企业园区的本地网络覆盖范围之前，已通过指定用户面节点连接至公网，则通过该步骤2033即可更新该指定用户面节点上该用户设备的连接信息，如该用户设备当前的位置区域标识、新的接入节点的用户面数据包转发地址等信息。
需要说明的是，对于EPS网络，由于用户面节点为存在SGW+PGW两个网元的系统，因此，控制面节点可能只需更新SGW上的连接信息，当两个网元上的连接信息都需要更新时，则控制面节点可以通过SGW和PGW交互。相应地，对于eLTE网络，由于用户面节点为存在SGW-U+PGW-U两个网元的系统，因此，控制面节点可能只需更新SGW-U上的连接信息，当两个网元上的连接信息都需要更新时，则控制面节点可以通过SGW-U和PGW-U交互
步骤2034：对于位置区域发生变化的用户设备，若位置区域发生变化后对应的控制面节点也发生变化，则变化后的控制面节点向数据管理网元发送签约数据请求，请求获取该用户设备的签约数据。
数据管理网元接收该签约数据请求后，即可向该控制面节点回复针对该请求的响应消息，该响应消息中携带该用户设备的签约数据。
其中，该用户设备的签约数据可以包括该用户设备的资费、套餐等数据。数据管理网元为负责归属地用户签约数据的管理和维护的网元，具体地，对于下一代通信网络，该数据管理网元可以为签约数据中心等，对于EPS网络、eLTE网络和2G/3G网络，该数据管理网元可以为家乡用户寄存器(Home Subscriber Server，HSS)或者归属用户寄存器(Home Location Register，HLR)等。
其中，该变化后的控制面节点也即是当前位置区域对应的控制面节点，而且，接入节点也是该将位置区域标识发送至该变化后的控制面节点中，由该变化后的控制面节点执行相关步骤。
另外，对于位置区域发生变化的用户设备，若位置区域发生变化后对应的控制面节点没有发生变化，则该用户设备的签约数据可以在该用户设备的位置区域发生变化之前接入该控制面节点时，由该控制面节点从签约数据中心获取得到。
步骤2035：根据该位置区域标识，确定至少一个本地网络标识。
步骤2036：将该至少一个本地网络标识发送给该用户设备。
需要说明的是，上述步骤2032-2034均为可选步骤，控制面节点可以执行也可以不执行，本发明实施例对此不做限定。
另外，还需要说明的是，接收到用户设备的接入请求后，控制面节点还可以向用户设备发送接入接受消息，如针对位置区域更新请求的位置区域更新接受消息，或者针对附着请求的附着接受消息。本发明实施例中，控制面节点可以在接入接受消息中将该至少一个本地网络标识发送给用户设备，也可以通过其他单独的消息进行发送，比如，可以在类似与EPS网络中网络侧用于通知网络名称和时区信息的EMM Information消息中或者其他单独定义的消息中发送该至少一个本地网络标识。而且，通过其他单独的消息进行发送时，该单独的消息可以在位置区域更新/附着流程中发送给用户设备，也可以在位置区域更新/附着流程结束后发送给用户设备，本发明实施例对此均不做限定。
步骤204：用户设备接收控制面节点发送的该至少一个本地网络标识，向控制面节点发送建立连接请求，该建立连接请求携带该用户设备基于该至少一个本地网络标识选择的第一本地网络标识。
具体地，用户设备接收到控制面节点发送的该至少一个本地网络标识时，可以显示该至少一个本地网络标识，而用户即可基于该用户设备显示的该至少一个本地网络标识，根据自身需要从中选择出一个想要接入的本地网络，或者质量较高的本地网络。比如，若某用户是企业A的员工，则进入企业A的园区后，可以基于显示的至少一个本地网络标识，选择企业A的本地网络接入；又比如，若某用户在咖啡吧B喝咖啡，则可以基于显示的至少一个本地网络标识，选择咖啡吧B的本地网络接入。
用户设备选择好本地网络后，即可发起携带所选择的第一本地网络标识的建立连接请求，该建立连接请求用于请求控制面节点建立该用户设备到该第一本地网络标识指示的第一本地网络的连接。
步骤205：控制面节点接收该用户设备发送的建立连接请求，根据该第一本地网络标识，建立该用户设备到第一本地网络的连接。
具体地，该控制面节点可以根据该第一本地网络标识，确定该第一本地网络标识对应的本地用户面节点，并向该本地用户面节点发送连接通知，通知该本地用户面节点建立用户设备到该第一本地网络的连接，也即是，将该用户设备接入该第一本地网络。
其中，根据该第一本地网络标识的不同，确定该第一本地网络标识对应的本地用户面节点的过程也不同，具体可以包括但不限定于以下几种方式：
1)若该第一本地网络标识为该第一本地网络对应的接入点名称，则根据该接入点确定该本地用户面节点。
2)若该第一本地网络标识为该第一本地网络的企业名称或者网络名称，则先根据本地网络标识和接入点名称的对应关系，确定对应的接入点名称，再根据接入点名称确定该本地用户面节点。
其中，本地网络标识和接入点名称的对应关系可以通过操作维护端预先配置在控制面功能网元上，也可以从其他网元，如签约数据中心、家乡用户寄存器、策略功能网元等中获取，本发明实施例对此不做限定。
其中，根据接入点名称确定本地用户面节点的方法有多种，如向域名系统(Domain Name System，DNS)等其他网元查询接入点名称对应的本地用户面节点地址，又如通过控制面功能节点上的本地配置确定接入点名称对应的本地用户面节点地址。
进一步地，根据该第一本地网络标识，建立该用户设备到第一本地网络的连接之前，该控制面节点可以先判断该至少一个本地网络标识是否包括该第一本地网络标识；当该至少一个本地网络标识包括该第一本地网络标识时，执行根据该第一本地网络标识，建立该用户设备到第一本地网络的连接的步骤。另外，当该至少一个本地网络标识不包括该第一本地网络标识时，则不执行根据该第一本地网络标识，建立该用户设备到第一本地网络的连接的步骤。
也即是，控制面节点接收到用户设备发送的第一本地网络标识之后，可以先对该第一本地网络标识进行核查，核查该第一本地网络标识是否属于该控制面节点向该用户设备发送的该至少一个本地网络标识，若核查通过，则建立该用户设备到该第一本地网络的连接，若核查未通过，则不建立该用户设备到该第一本地网络的连接。通过核查，提高了连接的准确性，避免了所连接的第一本地网络可能不是该位置区域的本地网络，或者不是允许接入的本地网络。
进一步地，控制面节点建立该用户设备到该第一本地网络的连接之后，还可以向用户设备回复连接建立响应。
进一步地，对于位置区域发生变化的用户设备，若该用户设备在位置区域发生变化前已通过指定用户面节点建立网络连接，则在第一本地网络的连接建立成功后，还可以释放该用户设备通过该指定用户面节点建立的网络连接。
其中，释放连接的步骤可以由用户设备触发，也可以由控制面节点触发，本发明实施例对此不做限定。比如，在与第一本地网络的连接建立成功之后，用户设备可以向控制面节点发送连接删除请求，请求控制面节点删除通过该指定用户面节点建立的网络连接；或者，向用户设备发送连接建立响应后，由控制面节点通知指定用户面节点和用户设备删除之前建立的网络连接。
本发明实施例中，当用户设备进入某一位置区域并向接入节点发送接入请求时，接入节点可以向控制面节点发送指示该用户设备当前所处的位置区域的位置区域标识，由于控制面 节点可以根据该位置区域标识，确定至少一个本地网络标识，并将该至少一个本地网络标识发送给用户设备以供用户设备进行选择，因此用户即可通过该用户设备自主选择需要接入的本地网络，也即是，自主选择想要接入的本地网络或质量较高的本地网络，从而提高了本地网络的连接效果和灵活性，扩展了本地网络的连接方式。同时，移动通信网络运营商也无需为每一个本地网络都规划特定的位置区域标识，部署专有的控制面节点，可以将多个本地网络规划到同一个位置区域内，控制面节点可以同时服务多个相邻的位置区域，降低了部署成本。
为了使本发明的技术方案更加清楚，下面将以下一代移动通信网络为例，对本发明的技术方案作进一步地详细描述：
由上述实施环境的介绍可知，当该移动通信网络为下一代移动通信网络时，上述控制面节点为控制面功能网元、用户面节点为用户面功能网元、数据管理网元可以为签约数据中心。
图3是本发明实施例提供的一种本地网络的连接方法流程图，该方法的交互主体为用户设备、接入节点、控制面功能网元、用户面功能网元和签约数据中心。若该用户设备进入某企业园区之前已通过指定用户面功能网元建立了与公网的连接，且进入该企业园区后位置区域发生了变化，则参见图3，该用户设备通过该下一代移动通信网络连接至该位置区域的本地网络的具体流程可以包括以下步骤：
步骤301：用户设备进入企业园区后，向接入节点发送位置区域更新请求。
步骤302：接入节点接收该位置区域更新请求，确定该用户设备当前所处的位置区域，向控制面功能网元发送位置区域标识。
步骤303：控制面功能网元对该用户设备进行鉴权，确定该用户设备的安全性。
步骤304：控制面功能网元通知该指定用户面功能网元更新连接。
步骤305：若用户设备进入该企业园区后，控制面功能网元也发生变化，则该控制面功能网元向签约数据中心发送签约数据请求，请求获取该用户设备的签约数据。
步骤306：控制面功能网元根据该位置区域标识，确定至少一个本地网络标识。
步骤307：控制面功能网元向用户设备发送位置更新接受消息，该位置更新接受消息携带该至少一个本地网络标识。
步骤308：用户设备基于该至少一个本地网络标识选择第一本地网络标识，并向控制面功能网元发送建立连接请求，该建立连接请求携带该第一本地网络标识。
步骤309：控制面节点接收该用户设备发送的建立连接请求，根据该第一本地网络标识，通过本地用户面功能网元建立该用户设备到第一本地网络的连接。
步骤310：控制面节点向用户设备发送连接建立响应。
步骤311：用户设备向控制面节点发送连接删除请求，请求删除通过该指定用户面功能网元建立的到公网的连接。
步骤312：控制面节点接收该连接删除请求，删除通过指定用户面功能网元建立的该用户设备到公网的连接。
步骤313：控制面节点向用户设备发送连接删除响应。
进一步的，如果下一代移动通信网络中，控制面功能网元进一步的拆分为会话管理功能、移动性管理功能等独立的功能网元。则控制面功能网元的功能可以由会话管理功能和移动性 管理功能配合完成，具体为：
步骤302：接入节点接收该位置区域更新请求，确定该用户设备当前所处的位置区域，向移动性管理功能发送位置区域标识，移动性管理功能将位置区域标识通知给会话管理功能。
步骤304：会话管理功能通知该指定用户面功能网元更新连接。
步骤305：若用户设备进入该企业园区后，移动性管理功能也发生变化，则该移动性管理功能向签约数据中心发送签约数据请求，请求获取该用户设备的签约数据。
步骤306：会话管理功能根据该位置区域标识，确定至少一个本地网络标识。
步骤307：会话管理功能将所述至少一个本地网络标识通知给用户设备，可以通过移动管理功能向用户设备发送位置更新接受消息，该位置更新接受消息携带该至少一个本地网络标识。
步骤308：用户设备基于该至少一个本地网络标识选择第一本地网络标识，并向会话管理功能发送建立连接请求，该建立连接请求携带该第一本地网络标识。所述建立连接请求由移动性管理功能转发给会话管理功能。
步骤309：会话管理功能接收该用户设备发送的建立连接请求，根据该第一本地网络标识，通过本地用户面功能网元建立该用户设备到第一本地网络的连接。
步骤310：会话管理功能向用户设备发送连接建立响应。
步骤311：用户设备向会话管理功能发送连接删除请求，请求删除通过该指定用户面功能网元建立的到公网的连接。
步骤312：会话管理功能接收该连接删除请求，删除通过指定用户面功能网元建立的该用户设备到公网的连接。
步骤313：会话管理功能向用户设备发送连接删除响应。
需要说明的是，本发明实施例仅是以在下一代移动通信网络中以上述流程将用户设备连接至本地网络为例进行说明，而实际应用中，还可以参考上述图2的方法实施例采用其他实现形式，且具体实现过程详见上述图2方法实施例，这里不再一一赘述。另外，EPS网络、eLTE网络和2G/3G网络的具体实现过程也可以参考上述图2方法实施例，这里也不再一一赘述。

可选地，参见图4B，该装置还包括判断模块405，用于判断确定模块402确定的至少一个本地网络标识是否包括第二接收模块403接收的第一本地网络标识；
该建立关系模块404，还用于当确定模块402确定的至少一个本地网络标识包括第二接收模块403接收的第一本地网络标识时，根据该第一本地网络标识，建立用户设备到第一本地网络的连接。
本发明实施例中，当用户设备进入某一位置区域时，该本地网络的连接装置可以将该位置区域内的至少一个本地网络标识发送至该用户设备，因此用户可以通过用户设备自主选择 需要接入的本地网络，也即是，自主选择想要接入的本地网络或质量较高的本地网络，从而提高了本地网络的连接效果和灵活性，扩展了本地网络的连接方式。同时，移动通信网络运营商也无需为每一个本地网络都规划特定的位置区域标识，部署专有的控制面节点，可以将多个本地网络规划到同一个位置区域内，控制面节点可以同时服务多个相邻的位置区域，降低了部署成本。
以上第一接收模块401和第二接收模块403可以为接收机，且该第一接收模块401和第二接收模块403可以集成在一个收发模块中，对应于硬件实现为收发机。以上确定模块402、建立连接模块404和判断模块405等可以以硬件形式内嵌于或独立于该本地网络的连接装置的处理器中，也可以以软件形式存储于该本地网络的连接装置的存储器中，以便于处理器调用执行以上各个模块对应的操作。该处理器可以为中央处理单元(CPU)、微处理器、单片机等。
需要说明的是：上述实施例提供的本地网络的连接装置在实现本地网络的连接方法时，仅以上述各功能模块的划分进行举例说明，实际应用中，可以根据需要而将上述功能分配由不同的功能模块完成，即将设备的内部结构划分成不同的功能模块，以完成以上描述的全部或者部分功能。另外，上述实施例提供的本地网络的连接装置与本地网络的连接方法实施例属于同一构思，其具体实现过程详见方法实施例，这里不再赘述。
上述本发明实施例序号仅仅为了描述，不代表实施例的优劣。
本领域普通技术人员可以理解实现上述实施例的全部或部分步骤可以通过硬件来完成，也可以通过程序来指令相关的硬件完成，所述的程序可以存储于一种计算机可读存储介质中，上述提到的存储介质可以是只读存储器，磁盘或光盘等。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
