- TDL+TD-SCDMA+GSM For example, China Mobile Communications Corporation requires that when the terminal is in China, the mode of operation is TDL+TD-SCDMA+GSM. When roaming abroad, TDL+FDL+WCDMA+GSM is turned on, and then, for example, China Telecom requires domestic use.

Abstract
一种找网的方法、终端和计算机可读存储介质，该方法包括：所述终端设备在没有网络后按照预定的规则搜索网络；当所述终端设备搜索网络成功时，根据解析出的移动国家号MCC切换所述终端设备支持的制式和模式。
Description
本申请涉及但不限于互联网技术，尤其涉及一种找网的方法、装置和计算机可读存储介质。
随着通信技术的发展，移动终端支持的模式和频段越来越多，例如目前在国内常见的有诸如支持FDL、TDL、WCDMA、TD-SCDMA、GSM、HRPD、CDMA1X 7模18个频段。另外，随着国际化的步伐，运营商漫游资费在不断下降、漫游策略也不断的变化，为了更好的提升用户体验，提升运营商资源的利用率，国内各运营商对终端制式和漫游模式也提出了诸多要求。
例如，中国移动通信集团公司要求，当终端在国内时，开启的模式为TDL+TD-SCDMA+GSM，漫游到国外时，开启TDL+FDL+WCDMA+GSM，再例如中国电信要求在国内使用的模式为TDL+FDL+HRPD+CDMA1X，在国外非日韩地区开启TDL+FDL+WCDMA+GSM,在日韩地区要求开启FDL+TDL+WCDMA+HRPD+CDMA1X制式。
由于在非漫游地区和漫游地区之间移动时，移动终端需要进行移动终端制式模式切换，目前手机普遍的做法是通过定时器的方法切换移动终端的模式。例如当终端从非漫游国家到漫游国家时，首先会按非漫游模式制式进行搜网，同时启动一个定时器，当定时器超时后，没有国内网络时，则开启漫游模式制式，再进行搜网找网，待找到漫游网络后在发起注册过程。例如目前的marvell平台设置的是3分钟，MTK平台设置的大约是2分钟，高通平台前期设置的是10分钟，后来发现漫游下找网时间太长将定时器修改到1分钟。
上述技术方案普遍的做法是通过设置一个定时器，当定时器超时后，移动终端进行模式切换，再进行搜网注册网络。当前移动终端在漫游网络和非漫游网络移动时，虽然可通过定时器的方式进行漫游模式切换找网注册，但这个时间一般比较固定，死板，当时间设置不合理时，会导致移动终端在漫
游和非漫游状态切换时，找网时延长等问题。

附图概述
图1为本发明实施例一中的找网的方法的流程图；
图2为本发明实施例一中的移动终端漫游场景示意图；
图3为本发明实施例一中的移动终端找网的流程图；
图4为本发明实施例二中的找网的装置的示意图。
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
本发明是实施例提供了一种找网的方法、装置和计算机可读存储介质，实现了终端设备快速的切换漫游和非漫游模式，加速了终端设备搜网注册的流程。
实施例一
如图1所示，本发明实施例提供一种找网的方法，应用于终端设备，所述方法包括步骤S101～S102：
S101、所述终端设备在没有网络后按照预定的规则搜索网络。
可选地，终端设备没有网络后按照预定的规则搜索网络包括步骤S201～S203：
S201、终端设备没有网络后，判断终端设备是否为首次找网
S202、当判定终端设备是首次找网时，根据终端设备支持的全制式和全频段搜索网络。
S203、当判定终端设备不是首次找网时，根据终端设备上一次找网成功后开启的模式和制式搜索网络。
需要说明的是，本发明实施例可以是终端设备在同一国家出现没有网络后的找网，也可以是漫游地与非漫游地之间切换时的找网。这里所说的终端没有网络后触发找网可以是以下场景：
1)终端设备从一个国家切换到另一个国家后网络丢失，会触发找网，进行模式和制式的切换。
2)终端设备启动飞行模式后网络丢失，当从飞行模式重新回到普通模式时就需要触发找网。
3)终端设备进入到信号不好的区域，如电梯、地下室等场所，网络可能会丢失，当重新进入信号良好的区域时会触发找网。
4)终端设备首次开机时也会触发找网。
S102、当终端设备搜索网络成功时，根据解析出的移动国家号MCC切换终端设备支持的制式和模式。
可选地，当终端设备搜索网络成功时，根据解析出的移动国家号MCC切换所述终端设备支持的制式和模式包括步骤S301～S302：
S301、当终端设备搜索网络成功时，终端设备解析搜索出的网络的系统广播消息，根据系统广播消息解析出MCC。
S302、根据MCC判断终端设备的当前位置，根据终端设备的当前位置切换到终端设备当前对位置对应的制式和模式。
例如，根据MCC判断终端设备的当前位置是美国，则将终端设备的制式和模式切换到美国对应的制式和模式。
可选地，该方法还包括：当判定所述终端设备不是首次找网时，根据所述终端设备上一次找网成功后开启的模式和制式搜索网络后，当终端设备搜索网络不成功时，根据协议和/或平台策略再次搜索网络M次仍不成功时，开启终端设备的所有制式和频段继续搜索网络；或者，
当所述终端设备搜索网络不成功时，根据协议和/或平台策略再次搜索网络N次后成功时，根据解析出的移动国家号MCC切换所述终端设备支持的制式和模式，其中，M、N为搜索网络的次数；M、N为正整数，0＜N≤M。
需要说明的是，M可以是预先设定的再次搜索的最大数。例如，预设M为4，这样当终端设备搜索网络不成功时，根据协议和/或平台策略再次搜索网络，如果在第3次搜索网络成功时，则根据MCC切换终端设备支持的制式和模式。如果搜索到底4次仍然不成功，就不再根据协议和/或平台策略继续搜索网络了，而且终端设备的所有制式和频段继续搜索网络。
当然，还可以将M设置为0，这时，当终端设备搜索网络不成功时，无需根据协议和/或平台策略搜索网络，而是直接开启所述终端设备的所有制式和频段继续搜索网络。
如图2所示，为本发明实施例的移动终端101漫游场景图。
移动无线网络100、200可以是TDL网络、FDL网络等，网络支持标准的3GPP和3GPP2协议标准，能广播系统消息并携带MCC等网络参数等。
移动终端101支持多模多频段，例如支持TDL、FDL、WCDMA、TD-SCDMA、GSM，或者支持TDL、FDL、WCDMA、TD-SCDMA、GSM、HRPD、CDMA1X等多模式。移动终端101支持在非漫游网络和漫游网络之间进行多模式切换功能。
无线通信网络终端/无线发射装备102、202，例如基站，增强型基站等,能向终端发射无线信号和接收和解析移动终端无法信号。
在本发明实施例中，移动终端101从一个无线网络100移动到另外一个无线网络200时，如果网络丢失了，移动终端101会重新进行网络搜索，当搜索到网络时，尝试解析网线网络的系统消息，解析MCC等无线网络参数，移动终端根据无线网络参数MCC的值，确定当前终端所处的网络环境是非漫游网络还是非漫游网络，从而决定移动终端的制式和模式，其中还包含频段等信息。
如图3所示，移动终端找网的流程如下，包括步骤S401～S412：
S401、移动终端进行漫游地和非漫游地的场景切换。
S402判定是否是首次找网；如果是首次找网转步骤S407，如果不是首次找网转步骤S403。
S403、移动终端根据上一次找网成功后启动的制式和模式进行搜索网络。
例如，可以根据协议规则对RPLMN进行搜索。
S404、判断搜索网络是否成功；如果成功转步骤S409；如果不成功转步骤S405：
S405、根据移动终端本身策略反复进行搜索M次。
S406、判断搜索网络是否成功；如果成功转步骤S409；如果不成功转步骤S407。
S407、移动终端需要开启移动终端所支持的所有制式和频段，进行全制式，全频段的搜网。
S408、判断搜索网络是否成功；如果搜索网络成功转步骤S409；如果搜索网络不成功转步骤S407。
S409、如果移动终端搜索网络获取到相应的小区，那么尝试解析读取系统消息，并获得系统消息MCC等参数。
S410、读取到MCC后，根据MCC判断终端是否漫游。
S411、切换移动终端所支持的制式和模式。
S412、根据协议规则进行PLMN选择，小区选择以及向相应的网络上发起注册。
在本实施例中，次数M可由移动终端平台可自身设定，次数M设置的越小，那么移动终端开启全频段扫描的时间越短，在国际漫游情况下，移动终端进行全频段、全制式的搜网概率也就会增大，搜索到网络的可能性也越大，同时移动终端进行模式切换的时间也越短。
次数M最小可以设定为0，当M设定为0时，在步骤S404中如果判断搜索网络不成功时则直接执行步骤S407，而不需要执行步骤S405和步骤S406。
同时，当次数M设定为正整数时，也就是M不为0。
例如，设定M为4时，移动终端可以按照本身策略反复搜索最多4次，在这4次中，每搜索一次可以判断是否搜索到网络，如果在第3次搜索中搜网到网络了，那么就可以直接转入步骤S409，这样就不需要再进行第4次的搜索了。如果第4次也没有搜索到网络，则需要执行步骤S407开启所有制式和频段继续搜索。
