本发明实施例提供了一种漫游结束后的网络搜索方法及设备，可以当终端设备漫游结束后，自动将网络搜索模式由手动选网切换到自动选网，以注册到HPLMN，使用户可以正常使用终端设备进行通信。以下分别进行详细说明。
请参阅图1，图1是本发明实施例公开的一种漫游结束后的网络搜索方法的流程示意图。
本发明实施例中，判断终端设备当前的网络搜索模式是否为手动选网；若所述网络搜索模式为手动选网，则统计所述终端设备处于无服务状态的时间； 若所述终端设备处于无服务状态的时间超过预设时间阈值，则将所述网络搜索模式切换到自动选网。实施本发明实施例，可以当终端设备漫游结束后，自动将网络搜索模式由手动选网切换到自动选网，以注册到HPLMN，使用户可以正常使用终端设备进行通信。
其中，图1所示的漫游结束后的网络搜索方法可以包括以下步骤：
101、判断终端设备当前的网络搜索模式是否为手动选网。
本发明实施例中，终端设备可为智能手机、智能手表、掌上电脑、平板电脑、个人数字助理(Personal Digital Assistant，PDA)、销售终端(Point of Sales，POS)等，本发明实施例后续不作复述。
本发明实施例中，当用户在国外使用国际漫游服务时，为了选择与用户的归属地运营商合作的网络信号更好、资费更为优惠的漫游地运营商网络，往往会将终端设备的网络搜索模式调整为手动选网模式，之后用户从终端设备上列出的可接入的网络列表中自主选取想要接入的网络。然而，这种使用方法所造成的问题是，当用户从国外回国，需要接入HPLMN时，由于网络搜索模式为手动选网，终端设备会继续搜索之前国际漫游时用户所选择的网络，造成无法接入HPLMN。
因此，当终端设备重新开机后，可以判断终端设备当前的网络模式是否为手动选网，若为手动选网模式，则需要根据后续是否可以搜索到网络来对搜网策略进行一定的调整。
102、若上述网络搜索模式为手动选网，则统计终端设备处于无服务状态的时间。
本发明实施例中，若终端设备的网络搜索模式为手动选网，则统计终端设备处于无服务状态的时间；若终端设备能在预设的时间阈值内搜索到网络，脱离无服务状态，则说明可能是所在的地理位置网络信号较弱造成的搜网较慢；若搜索网络的时间超过预设时间阈值，则终端设备可能是由漫游地回到归属地，归属地没有用户在手动选网模式下选择的网络而造成的不能搜索到网络。
103、若终端设备处于无服务状态的时间超过预设时间阈值，则将上述网络搜索模式切换到自动选网。
本发明实施例中，为解决用户由漫游地回到归属地，归属地没有用户在手 动选网模式下选择的网络而造成的不能搜索到网络的问题，可以判断终端设备的网络搜索模式为手动选网，并且处于无服务状态的时间超过预设时间阈值后，将终端设备的网络搜索模式切换到自动选网。终端设备在自动选网模式下，根据选网策略，优先搜索已登记公共陆地移动网络(Registered Public Land Mobile Network，RPLMN)和HPLMN，即可较为迅速地搜索到归属地网络并进行接入。
在图1所描述的方法中，当判断终端设备的网络搜索模式为手动选网后，统计终端设备处于无服务状态的时间；若终端设备处于无服务状态的时间超过预设时间阈值，则可推断终端设备为由国际漫游地回到归属地，因此，将终端设备的网络搜索模式切换为自动选网以搜索到HPLMN来进行接入。由此可见，利用图1所描述的方法，可以当终端设备漫游结束后，自动将网络搜索模式由手动选网切换到自动选网，以注册到HPLMN，使用户可以正常使用终端设备进行通信。
请参阅图2，图2是本发明实施例公开的另一种漫游结束后的网络搜索方法的流程示意图。如图2所示，该方法可以包括以下步骤：
201、判断终端设备当前的网络搜索模式是否为手动选网。
本发明实施例中，当终端设备重新开机后，可以判断终端设备当前的网络模式是否为手动选网，若为手动选网模式，则需要根据后续是否可以搜索到网络来对搜网策略进行一定的调整。
202、若上述网络搜索模式为手动选网，则查询终端设备的服务状态记录。
203、判断上述服务状态是否由漫游状态切换到本地状态。
本发明实施例中，终端设备的服务状态会记录终端设备在为用户提供服务时，是处于漫游状态还是本地状态。若查询终端设备的服务状态，为由漫游状态切换到本地状态，则说明终端设备之前在国外使用，为国际漫游模式，现在回到归属地。
作为一种可选的实施方式，终端设备还可以获取当前的地理位置，判断当前的地理位置是否为用户的归属地公共陆地移动网络HPLMN所属的地理位置。若是，则用户的终端设备处于无服务状态的话，可能是由于在手动选网时，将网络选择为本地所不支持的网络而导致。因此，可以当终端设备处于无服务 状态的时间超过预设时间阈值的情况下，将终端设备的网络搜索模式切换为自动选网来搜索到本地的网络。
204、若上述服务状态由漫游状态切换到本地状态，则统计终端设备处于无服务状态的时间。
本发明实施例中，当确定了终端设备的网络搜索模式为手动选网，且为由国外回到归属地后，统计终端设备处于无服务状态的时间，若处于无服务状态的时间超过预设时间阈值，则需要从手动选网切换为自动选网，以搜索到HPLMN进行接入。
205、若终端设备处于无服务状态的时间超过预设时间阈值，则将上述网络搜索模式切换到自动选网。
作为一种可选的实施方式，使终端设备的应用处理器发送网络搜索模式切换指令至终端设备的基带处理器，以使基带处理器将网络搜索模式切换为自动选网。
206、获取终端设备中预置的上述HPLMN的频段信息。
本发明实施例中，终端设备中为了搜索不同运营商的网络，需预置与运营商的网络的频段所对应的射频驱动。当需要全网搜索时，需要加载所有的射频驱动来进行全网搜索，这样的搜网策略会增加终端设备的功耗，并造成通信信号的稳定性降低。因此，当已知所需搜索的网络为HPLMN后，可以仅加载对应HPLMN频段信息的射频驱动，卸载其他射频驱动，以降低基带功耗，保证通信稳定性。
207、加载对应上述频段信息的射频驱动，卸载不对应上述频段信息的射频驱动。
208、利用上述对应上述频段信息的射频驱动搜索上述HPLMN以进行注册。
本发明实施例中，终端设备为了降低网络搜索的功耗，会将无线电接入技术RAT进行限制，从而避免网络搜索范围过大而造成功耗增加。针对这种情况，终端设备可以获取其预置的HPLMN的网络制式，并且查询终端设备当前搜索的RAT，若RAT中不包括HPLMN的网络制式，则将RAT修改为包含HPLMN的网络制式，以帮助终端设备搜索到可用的网络。
在图2所描述的方法中，当判断终端设备的网络搜索模式为手动选网后，查询终端设备的服务状态记录；若服务状态由漫游状态切换到本地状态，则统计终端设备处于无服务状态的时间；若终端设备处于无服务状态的时间超过预设时间阈值，则可推断终端设备为由国际漫游地回到归属地，因此，将终端设备的网络搜索模式切换为自动选网以搜索到HPLMN来进行接入。由此可见，利用图2所描述的方法，可以当终端设备漫游结束后，自动将网络搜索模式由手动选网切换到自动选网，以注册到HPLMN，使用户可以正常使用终端设备进行通信。
请参阅图3，图3是本发明实施例公开的一种漫游结束后的网络搜索设备的结构示意图。如图3所示，该终端设备可以包括：
第一判断单元301，用于判断终端设备当前的网络搜索模式是否为手动选网。
本发明实施例中，当用户在国外使用国际漫游服务时，为了选择与用户的归属地运营商合作的网络信号更好、资费更为优惠的漫游地运营商网络，往往会将终端设备的网络搜索模式调整为手动选网模式，之后用户从终端设备上列出的可接入的网络列表中自主选取想要接入的网络。然而，这种使用方法所造成的问题是，当用户从国外回国，需要接入HPLMN时，由于网络搜索模式为手动选网，终端设备会继续搜索之前国际漫游时用户所选择的网络，造成无法接入HPLMN。
因此，当终端设备重新开机后，可以判断终端设备当前的网络模式是否为手动选网，若为手动选网模式，则需要根据后续是否可以搜索到网络来对搜网策略进行一定的调整。
统计单元302，用于当上述网络搜索模式为手动选网时，统计终端设备处于无服务状态的时间。
本发明实施例中，若终端设备的网络搜索模式为手动选网，则统计终端设备处于无服务状态的时间；若终端设备能在预设的时间阈值内搜索到网络，脱离无服务状态，则说明可能是所在的地理位置网络信号较弱造成的搜网较慢；若搜索网络的时间超过预设时间阈值，则终端设备可能是由漫游地回到归属地，归属地没有用户在手动选网模式下选择的网络而造成的不能搜索到网络。
切换单元303，用于当终端设备处于无服务状态的时间超过预设时间阈值时，将上述网络搜索模式切换到自动选网。
作为一种可选的实施方式，该网络搜索设备还可以包括第三搜索单元，用于搜索已登记公共陆地移动网络RPLMN和/或归属地公共陆地移动网络HPLMN，以确定是否能接入RPLMN或HPLMN。其中，第三搜索单元可由下文中的第一搜索单元308或第二搜索单元313代替，故未在图中进行示出。
本发明实施例中，为解决用户由漫游地回到归属地，归属地没有用户在手动选网模式下选择的网络而造成的不能搜索到网络的问题，可以判断终端设备的网络搜索模式为手动选网，并且处于无服务状态的时间超过预设时间阈值后，将终端设备的网络搜索模式切换到自动选网。终端设备在自动选网模式下，根据选网策略，优先搜索已登记公共陆地移动网络(Registered Public Land Mobile Network，RPLMN)和HPLMN，即可较为迅速地搜索到归属地网络并进行接入。
本发明实施例可以根据上述方法示例对漫游结束后的网络搜索设备进行功能单元的划分，例如，可以对应各个功能划分各个功能单元，也可以将两个或两个以上的功能集成在一个处理单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。举例来说，上述第一判断单元301、统计单元302以及切换单元303可以集成到中央处理器(Central Processing Unit,CPU)之中。需要说明的是，本发明实施例中对单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
在图3所描述的设备中，当判断终端设备的网络搜索模式为手动选网后，统计终端设备处于无服务状态的时间；若终端设备处于无服务状态的时间超过预设时间阈值，则可推断终端设备为由国际漫游地回到归属地，因此，将终端设备的网络搜索模式切换为自动选网以搜索到HPLMN来进行接入。由此可见，利用图3所描述的设备，可以当终端设备漫游结束后，自动将网络搜索模式由手动选网切换到自动选网，以注册到HPLMN，使用户可以正常使用终端设备进行通信。

第二获取单元306，用于获取终端设备中预置的上述HPLMN的频段信息。
本发明实施例中，终端设备中为了搜索不同运营商的网络，需预置与运营商的网络的频段所对应的射频驱动。当需要全网搜索时，需要加载所有的射频驱动来进行全网搜索，这样的搜网策略会增加终端设备的功耗，并造成通信信号的稳定性降低。因此，当已知所需搜索的网络为HPLMN后，可以仅加载对应HPLMN频段信息的射频驱动，卸载其他射频驱动，以降低基带功耗，保证通信稳定性。

在图4A所描述的设备中，当判断终端设备的网络搜索模式为手动选网后，查询终端设备的服务状态记录；若服务状态由漫游状态切换到本地状态，则统计终端设备处于无服务状态的时间；若终端设备处于无服务状态的时间超过预设时间阈值，则可推断终端设备为由国际漫游地回到归属地，因此，将终端设备的网络搜索模式切换为自动选网以搜索到HPLMN来进行接入。由此可见，利用图4A所描述的设备，可以当终端设备漫游结束后，自动将网络搜索模式由手动选网切换到自动选网，以注册到HPLMN，使用户可以正常使用终端设 备进行通信。

在本发明实施例中，处理器501通过调用存储于存储器502中的程序代码，用于执行以下操作：
判断终端设备当前的网络搜索模式是否为手动选网；
若上述网络搜索模式为手动选网，则统计终端设备处于无服务状态的时间；
若终端设备处于无服务状态的时间超过预设时间阈值，则将上述网络搜索模式切换到自动选网。
作为一种可选的实施方式，处理器501通过调用存储于存储器502中的程序代码，还用于执行以下操作：
查询终端设备的服务状态记录；
判断上述服务状态是否由漫游状态切换到本地状态；
上述统计终端设备处于无服务状态的时间，包括：
