背景技术
随着网络技术的飞速发展，用户对网络的依赖性越来越大，无论是工作、学习、休闲娱乐等都离不开网络。近年来，用户对网络便捷性的要求也越来越高，尤其是在某些网络接口不足的场合，网络连接的共享就显得更加至关重要。因此，为了更大程度地方便用户的使用，MiFi(便携式宽带无线装置)随之出现。MiFi是一个便携式宽带无线装置，集调制解调器、路由器和接入点三者功能于一身，内置调制解调器可以接入一个无线信号，内部路由器可在多个用户和无线设备之间共享这一连接，故MiFi有时也被成为个人“热点”。
使用现有的MiFi，通过在MiFi中插入一张SIM(Subscriber Identity Module，用户身份识别模块)卡，网络侧通过数据网络接入互联网，用户侧则通过WiFi(Wireless-Fidelity，无线保真)网络为其他WiFi终端设备提供热点接入互联网。
但是，现有的MiFi会受限于其中安装的SIM卡所属运营商的网络状况，当所属运营商的网络情况较差时，将导致MiFi无法继续接入该网络，故无法继续为其他WiFi终端设备提供数据接入服务。

具体实施例
为使本发明实施例的目的、技术方案和优点更加清楚，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。
实施例一
参照图1，示出了本发明实施例一的一种MiFi的控制方法的步骤流程图。
本发明实施例的MiFi的控制方法可以包括以下步骤：
步骤101，监控当前已连接的源运营商的SIM卡对应的数据网络是否断开。
本发明实施例的MiFi中安装有至少两张不同运营商的SIM卡，每张SIM卡各自对应一种类型的数据网络，初始时MiFi可以连接其中的一张SIM卡对应的数据网络，该张SIM卡为源运营商的SIM卡。其中，初始时连接的数据网络可以为用户手动选择的一张SIM卡对应的数据网络，也可以为MiFi根据网络信号强度自动选择的强度较大的一张SIM卡对应的数据网络，本发明实施例对此并不加以限制。
在MiFi连接上源运营商的SIM卡对应的数据网络后，可以监控当前已连接的源运营商的SIM卡对应的数据网络是否断开，以确定是否需要连接其他运营商的SIM卡对应的数据网络。其中，监控可以为实时监控，也可以为按照设定的时间间隔监控，对于该时间间隔，本领域技术人员根据可以实际经验设置任意适用的数值，例如可以设置为5s、10s等，本发明实施例对具体的数值并不加以限制。
步骤102，若断开，则选取除源运营商的SIM卡之外的其他运营商的SIM卡作为目标运营商的SIM卡。
如果在步骤101中监控到当前已连接的源运营商的SIM卡对应的数据网络断开，则由于MiFi中安装有至少两张不同运营商的SIM卡，因此为了避免MiFi无法继续接入上述断开的网络而导致无法继续为其他WiFi终端设备提供数据接入服务，本发明实施例中可以进一步从除源运营商的SIM卡之外的其他运营商的SIM卡中选取一张作为目标运营商的SIM卡，然后可以连接至该目标运营商的SIM卡对应的数据网络，从而保证MiFi仍然能够接入数据网络。
步骤103，连接至目标运营商的SIM卡对应的数据网络。
本发明实施例提供的MiFi的控制方法，在MiFi中安装有至少两张不同运营商的SIM卡，当MiFi已连接某一源运营商的SIM卡对应的数据网络时，可以监控当前已连接的源运营商的SIM卡对应的数据网络是否断开，如果断开则可以选取除源运营商的SIM卡之外的其他运营商的SIM卡作为目标运营商的SIM卡，并连接至目标运营商的SIM卡对应的数据网络。因此，本发明实施例中即使由于当前已连接的数据网络的网络状况较差导致MiFi无 法继续接入该数据网络，MiFi仍然可以选择其他运营商的SIM卡对应的数据网络进行连接，故解决了现有技术中MiFi会受限于其中安装的SIM卡所属运营商的网络状况的问题，提升了用户体验。
实施例二
参照图2，示出了本发明实施例二的一种MiFi的控制方法的步骤流程图。
本发明实施例的MiFi的控制方法可以包括以下步骤：
步骤201，检测MiFi是否被开启WiFi热点功能。若被开启，则执行步骤202；若未被开启，则执行相应操作。
本发明实施例中，MiFi中安装有至少两张不同运营商的SIM卡。参照图3，示出了本发明实施例二的一种MiFi的结构示意图。该MiFi中包括SIM1、SIM2和SIM3这三张SIM卡，还包括主控制器和WiFi模块，SIM1、SIM2、SIM3和WiFi模块分别具有各自对应的网络信号。其中，三张SIM卡分别属于不同运营商(例如SIM1属于移动，SIM2属于联通，SIM3属于电信等)，主控制器主要用于对MiFi的网络侧的网络连接及用户侧连接至该MiFi的WiFi终端设备等进行控制，WiFi模块为实现MiFi的WiFi热点功能的模块，可以对WiFi模块进行开启和关闭(分别对应于WiFi热点功能的开启和关闭)。需要说明的是，图3所示的MiFi仅是用于举例说明，本发明实施例中的MiFi并不限定于包括如图3所示的SIM1、SIM2和SIM3这三张SIM卡，也可以仅包括其中的任意两张SIM卡，本发明实施例对此并不加以限制。
当MiFi的WiFi热点功能被开启后，则允许其他的WiFi终端设备通过该MiFi的WiFi热点接入该MiFi当前已连接的数据网络；当MiFi的WiFi热点功能被关闭后，则禁止其他的WiFi终端设备通过该MiFi的WiFi热点接入该MiFi当前已连接的数据网络。优选地，本发明实施例中可以检测MiFi是否被开启WiFi热点功能，进而根据检测结果确定是否对MiFi当前已连接的源运营商的SIM卡对应的数据网络的连接状态进行监控。
其中，检测MiFi是否被开启WiFi热点功能的过程可以为：检测MiFi中的WiFi模块是否被开启，若被开启则说明MiFi被开启WiFi热点功能。 在具体实现中，可以在MiFi中设置WiFi模块对应的开启和关闭选项，例如可以设置开启和关闭按钮等，当选择开启选项时MiFi可接收到开启WiFi模块的指令，接收到之后即可开启WiFi模块，当选择关闭选项时MiFi可接收到关闭WiFi模块的指令，接收到之后即可关闭WiFi模块。
步骤202，在检测到MiFi被开启WiFi热点功能后，监控当前已连接的源运营商的SIM卡对应的数据网络是否断开。若断开，则执行步骤203；若未断开，则执行相应操作。
考虑到在MiFi被开启WiFi热点功能后，才会允许其他的WiFi终端设备通过该MiFi的WiFi热点接入该MiFi当前已连接的数据网络，该种情况下如果MiFi的数据网络连接断开，则将导致其他的WiFi终端设备无法再继续通过该MiFi连接网络；而如果MiFi的WiFi热点功能关闭，该种情况下无论MiFi的数据网络连接是否断开，都将禁止其他的WiFi终端设备通过该MiFi的WiFi热点接入该MiFi当前已连接的数据网络，因此实际上无需对MiFi的网络连接进行监控。因此，优选地，本发明实施例中可以进一步限定在检测到MiFi被开启WiFi热点功能后，才会监控当前已连接的源运营商的SIM卡对应的数据网络是否断开；而如果检测到MiFi未被开启WiFi热点功能，则可以执行相应操作，该相应操作可以为继续重复执行检测MiFi是否被开启WiFi热点功能的过程。通过上述方式能够进一步降低MiFi的功耗，节省电能。
本发明实施例中，在MiFi的内部保存有路由表，该路由表中可以记载MiFi的网络连接信息等，以图3所示的MiFi为例，该路由表中可以分别记载SIM1、SIM2和SIM3这三张SIM卡各自对应的网络端口的名称、网络端口的状态、各自对应的运营商的名称等信息。其中，网络端口的状态包括连接和断开两种，例如MiFi当前已连接SIM1卡对应的数据网络，则路由表中记载的网络端口的状态分别为：SIM1为连接，SIM2和SIM3均为断开，后续如果SIM1卡对应的数据网络断开，则路由表中记载的网络端口的状态将自动更新，分别为：SIM1、SIM2和SIM3均为断开。因此，可以通过对路由表的监控来对当前已连接的源运营商的SIM卡对应的数据网络是否断开进行监控，故该步骤202可以包括：监控MiFi内部保存的路由表中记载的源运营商的SIM卡对应的网络端口状态是否由连接变换为断开；若是，则确 定当前已连接的源运营商的SIM卡对应的数据网络断开。
步骤203，若断开，则选取除源运营商的SIM卡之外的其他运营商的SIM卡作为目标运营商的SIM卡。
如果在步骤202中监控到当前已连接的源运营商的SIM卡对应的数据网络断开，则为了避免由于MiFi的数据网络连接断开而导致其他WiFi终端设备也无法再继续接入该数据网络，本发明实施例中MiFi可以自动选取其他运营商的SIM卡作为目标运营商的SIM卡，并基于该目标运营商的SIM卡连接数据网络。而如果监控到当前已连接的源运营商的SIM卡对应的数据网络未断开，则可以执行相应操作，该相应操作可以为继续重复执行监控当前已连接的源运营商的SIM卡对应的数据网络是否断开的过程。
优选地，本发明实施例中可以根据MiFi中安装的SIM卡个数的实际情况执行该步骤203的选取过程。具体可以包括以下两种情况：第一种情况：若MiFi中安装有两张不同运营商的SIM卡，则选取除源运营商的SIM卡之外的另一个运营商的SIM卡作为目标运营商的SIM卡。第二种情况：若MiFi中安装有至少三张不同运营商的SIM卡，则从除源运营商的SIM卡之外的其他运营商的SIM卡中选取网络信号强度最大的一个运营商的SIM卡作为目标运营商的SIM卡。以图3所示的安装有三张SIM卡的MiFi为例，如果源运营商的SIM卡为SIM1，则当SIM1的网络连接断开时，MiFi将从SIM2和SIM3中选取网络信号强度最大的一张SIM卡作为目标运营商的SIM卡。需要说明的是，对于其中对各个其他运营商的SIM卡的网络信号强度的判断过程，本领域技术人员根据实际经验采用任意适用的方式处理即可，本发明实施例对此不再详细论述。
步骤204，连接至目标运营商的SIM卡对应的数据网络。
在步骤204中选取出目标运营商的SIM卡后，MiFi即可自动连接至该目标运营商的SIM卡对应的数据网络，连接之后MiFi即可继续接入该目标运营商的SIM卡对应的数据网络，继续为其他WiFi终端设备提供数据接入服务。优选地，该步骤204可以包括：获取目标运营商的SIM卡对应的网络端口的名称；将MiFi内部保存的路由表中记载的网络端口的名称对应的网络端口状态由断开更新为连接。
以图3所示的MiFi为例，如果源运营商的SIM卡为SIM1，则当SIM1 的网络连接断开时，MiFi将从SIM2和SIM3中选取网络信号强度最大的一张SIM卡作为目标运营商的SIM卡，如选取SIM2作为目标运营商的SIM卡，选取之后将连接至该SIM2对应的数据网络。具体可以为获取SIM2对应的网络端口的名称，然后将该名称对应的网络端口状态由断开更新为连接，因此更新后路由表中记载的网络端口的状态分别为：SIM1为断开，SIM2为连接，SIM3为断开。
最后需要说明的是，上述步骤201～步骤204可以均为由图3所示的MiFi中的主控器执行的步骤。
与传统的MiFi解决方案相比，本发明实施例能够很好的克服仅安装单一SIM卡的MiFi方案的弊端。例如如果安装三张SIM卡(一张联通+一张移动+一张电信)，那么就能够更大限度的体现本方案的优势，当用户携带MiFi到达某区域时，如果联通没有信号时也可以使用移动的网络，移动没有信号时还可以使用电信的网络。从而极大地方便了用户的使用，提升用户体验。
实施例三
参照图4，示出了本发明实施例三的一种MiFi的控制方法的步骤流程图。
本发明实施例的MiFi的控制方法可以包括以下步骤：
步骤401，开启MiFi的WiFi热点功能。
如实施例二的步骤201所述，可以在MiFi中设置WiFi模块对应的开启和关闭选项，例如可以设置开启和关闭按钮等，当选择开启选项时MiFi可接收到开启WiFi模块的指令，接收到之后即可开启WiFi模块，也即开启MiFi的WiFi热点功能。
步骤402，执行路由表监控进程。
本发明实施例中，可以预先设定路由表监控进程，该进程主要用于对路由表的变化状况进行监控。
步骤403，监控路由表是否改变。若是，则执行步骤404；若否，则返回步骤402。
该步骤可以对应于实施例二的步骤202，可以为步骤202的具体实现过 程，因此该步骤监控路由表是否改变具体可以指：监控MiFi内部保存的路由表中记载的源运营商的SIM卡对应的网络端口状态是否由连接变换为断开。
步骤404，获取目标运营商的SIM卡对应的网络端口的名称，并更新路由表。
该步骤可以对应于实施例二的步骤203和步骤204，具体参照步骤203和步骤204的相关描述即可。
步骤405，刷新NAT表并相应设置SNAT表。
本发明实施例中，MiFi内部还可以保存NAT(Network Address Translation，网络地址转换)表和SNAT(Source Network Address Translation，源网络地址转换)表，其中NAT表中保存有MiFi对外的网络信息等(如当前对外的网络地址、对外的网络接口名称等)，SNAT表中保存有MiFi对外的网络信息和源网络的信息等。
在对上述路由表进行更新后，还可以刷新NAT表并相应设置SNAT表，具体可以为：将NAT表和SNAT表中保存的对外的网络信息均设置为目标运营商的SIM卡对应网络的信息。以图3所示的MiFi为例，如果源运营商的SIM卡为SIM1，则当SIM1的网络连接断开时，MiFi选取SIM2作为目标运营商的SIM卡，则刷新NAT表并相应设置SNAT表可以为：将NAT表和SNAT表中保存的对外的网络信息(即SIM1对应网络的信息)设置为SIM2对应网络的信息，例如将对外的网络地址设置为SIM2对应网络的地址，将对外的网络接口名称设置为SIM2对应网络的接口名称等。
对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明并不受所描述的动作顺序的限制，因为依据本发明，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本发明所必须的。
实施例四
参照图5，示出了本发明实施例四的一种MiFi的控制装置的结构框图。本发明实施例的MiFi中安装有至少两张不同运营商的SIM卡。
本发明实施例的MiFi的控制装置可以包括以下模块：
监控模块501，用于监控当前已连接的源运营商的SIM卡对应的数据网络是否断开；
选取模块502，用于在监控模块监控到断开时，选取除源运营商的SIM卡之外的其他运营商的SIM卡作为目标运营商的SIM卡；
连接模块503，用于连接至目标运营商的SIM卡对应的数据网络。
本发明实施例提供的MiFi的控制装置，在MiFi中安装有至少两张不同运营商的SIM卡，当MiFi已连接某一源运营商的SIM卡对应的数据网络时，可以监控当前已连接的源运营商的SIM卡对应的数据网络是否断开，如果断开则可以选取除源运营商的SIM卡之外的其他运营商的SIM卡作为目标运营商的SIM卡，并连接至目标运营商的SIM卡对应的数据网络。因此，本发明实施例中即使由于当前已连接的数据网络的网络状况较差导致MiFi无法继续接入该数据网络，MiFi仍然可以选择其他运营商的SIM卡对应的数据网络进行连接，故解决了现有技术中MiFi会受限于其中安装的SIM卡所属运营商的网络状况的问题，提升了用户体验。

获取子模块6031，用于获取目标运营商的SIM卡对应的网络端口的名称；
更新子模块6032，用于将MiFi内部保存的路由表中记载的网络端口的名称对应的网络端口状态由断开更新为连接。
与传统的MiFi解决方案相比，本发明实施例能够很好的克服仅安装单一SIM卡的MiFi方案的弊端。例如如果安装三张SIM卡(一张联通+一张移动+一张电信)，那么就能够更大限度的体现本方案的优势，当用户携带MiFi到达某区域时，如果联通没有信号时也可以使用移动的网络，移动没有信号时还可以使用电信的网络。从而极大地方便了用户的使用，提升用户体验。
