下文中将结合附图对本发明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。
图 1为本发明实施例的一种搜网的处理方法的流程图， 如图 1所示， 本 实施例的方法包括：
Sl l、 针对指定条件配置对应的搜网策略；
S12、检测到达到所述指定条件时，切换到与所述指定条件对应的搜网策 略进行搜网。
所述指定条件可以包括：
无线网络的信号指标低于阔值， 或者无线网络发生断网事件， 或者电池 电量达到预设门限值。
本实施例的方法可以解决相关技术中智能手机在无线网络环境较差或覆 盖较差的情况下， 因无线调制解调器模块反复搜网而导致手机耗电迅速的问 题。
本实施例中， 例如， 终端用户界面提供可配置的无线调制解调器模块的 省电模式， 配置模式通过命令发送给无线调制解调器， 当无线调制解调器模 块检测到网络环境较差时， 根据配置命令而釆取不同的搜网策略， 通过降低 搜网等耗电工作的频率以达到省电和延长电池使用时间的目的。 智能终端设置界面里有用户可配置的无线调制解调器省电菜单， 选项包 含但不限于以下几种： 正常配置模式： 即无线调制解调器以原有的方式进行搜网；
省电配置模式： 即无线调制解调器以省电方式进行搜网。
电池电量相关的配置模式： 即无线调制解调器根据电池电量达到预设的 门限值时， 自动切换到对应的配置模式。 在该电池电量相关的配置模式下， 电池电压由无线调制解调器自行获取。 无线调制解调器可根据电量状况自行 调节搜网行为， 整个过程不需要应用处理器的参与， 节省了电源消耗。
本实施例的支持可配置的省电搜网策略的无线调制解调器， 一旦选定某 省电搜网策略，无线调制解调器可在应用处理器不干预的情况下执行该策略， 以达到省电效果。
省电的具体做法， 即搜网策略可以是： 延长搜网等耗电行为的间隔时间， 在脱网或搜网失败后等待一段时间再尝试搜网。 无线调制解调器可以支持若 干种等待时间的计算策略， 在选定某种策略后还可设置对应的参数。
本实施例的方法也可支持电池电量相关的， 能自动切换省电模式的无线 调制解调器， 即调制解调器能随着电量变化， 选择不同的省电配置模式。
在智能终端上， 无线调制解调器模块是一个相对独立的系统， 其各个内 部模块的供电一般需要专门的电源管理模块（PMU )进行管理， 也有和其他 模块共用一个 PMU芯片的情况。 PMU芯片会把电池提供的电源转换为不同 的电压电流输出， 供无线调制解调器模块使用， 无线调制解调器模块可以从 PMU上获得电池电压等状态信息。 除了 PMU芯片以外， 智能终端还能通过 电量计芯片获得更精确的电池电量信息。电量计芯片通过实时监测电池电压、 电流和温度数据， 并结合预存的电池放电特性数据， 计算出电池剩余电量。
因此， 本实施例中， 电池电量可通过 PMU或者电量计获取。 无线调制解 调器只需在搜网的同时查询电池电量即可， 不用定时查询而额外耗电。
终端在进入充电等特殊场景时， 可以自动转换为正常配置模式， 充电结 束后再配置为原有的省电模式。

步骤 403 , 无线调制解调器开始找网， 如果网络注册成功则结束， 找网 失败后转至步骤 404。
步骤 404 ,以步进 Tstep增大 T,如果 T超过了最大间隔时间 Tmax,则 T=Tmax, 转至步骤 405。 Tstep和 Tma>^o Tmt相同，是存放于省电搜网策略 205中的参数。
步骤 405 , 无线调制解调器以时长为 T设定定时器 206 , 进入休眠。
图 7是本发明一应用示例的电池电量相关的省电配置模式下， 智能手机 脱网后的搜网流程图， 如图 7所示， 包括以下步骤：
步骤 501 , 智能手机发生脱网。
步骤 502 ,调制解调器查询省电搜网策略 205 , 确定当前省电模式为电池 电量相关。 从省电搜网策略 205获取电池门限和策略的对应关系。
步骤 503 , 无线调制解调器通过电源管理模块接口 203获得电池电压， 根据电压值从省电搜网策略 205中选取对应的省电模式。
步骤 504 , 按照获得的省电模式开始休眠和搜网动作， 方法同图 4。 期间 如果网络注册成功则结束， 找网失败后转至步骤 505。
步骤 505 , 无线调制解调器器通过电源管理模块接口 203获取电池电压， 从省电搜网策略 205中检查是否需要变更省电模式。 如果需要， 则转至步骤 503 , 不需要， 则转至步骤 504。 本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成， 所述程序可以存储于计算机可读存储介质中， 如只读 存储器、 磁盘或光盘等。 可选地， 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地， 上述实施例中的各模块 /单元可以釆用 硬件的形式实现， 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。
