附图概述
图 1是现有技术中的 WAPI移动终端的功能结构图;
图 3是实施例中降低 WAPI移动终端功耗的方法流程图;
图 4是具体实施例中降低 WAPI移动终端功耗的方法流程图。
本发明的较佳实施方式
如图 2所示, 降低功耗的 WAPI移动终端相比图 1所示的 WAPI移动终 端, 增加了分别与处理器模块 101和 WAPI通信模块 103相连的动态緩存模 块 105;
用户接口模块 102, 用于用户人机交互设备与处理器模块 101 间的数据 交互; 移动终端的人机交互设备是终端屏幕和键盘;
WAPI通信模块 103 ,用于通过 WAPI协议与 WAPI网络的无线访问节点 处进行数据交互, 并将从无线访问节点处收到的 WAPI数据发送至处理器模 块 101或动态緩存模块 105;
存储模块 104, 用于根据处理器模块 101的控制存储 WAPI数据; 处理器模块 101 , 用于控制整个系统的正常运行、 接收外部控制信号的 输入和对 WAPI传输数据进行处理; 还用于根据 WAPI业务的实时性要求设 置緩存存储器的数据量阔值, WAPI业务的实时性要求越高, 设置的数据量 阔值越低; 还用于在 WAPI业务数据进行緩存过程中, 处于休眠状态或处理 优先级高于所述 WAPI业务的任务, 对 WAPI业务数据不予监控和处理; 还 用于在收到所述动态緩存模块的触发消息后即在緩存的 WAPI业务数据的数 据量累积达到所述数据量阔值后, 将緩存的 WAPI业务数据搬移到所述存储 模块, 并再次进入休眠状态或继续处理优先级高于所述 WAPI业务的任务; 动态緩存模块 105, 用于接收所述 WAPI通信模块发送的 WAPI业务数 据并緩存; 还用于在緩存的 WAPI业务数据的数据量累积达到所述处理器模 块设置的数据量阔值后, 向所述处理器模块 101发送触发消息;
此动态緩存模块 105 可以是低功耗的可编程逻辑门阵列 (Field
Programmable Gate Array, 简称 FPGA ) 芯片, 此 FPGA芯片内部的随机存取 内存( Random Access Memory , 简称 RAM)存储緩存的 WAPI数据。
WAPI移动终端根据 WAPI业务的实时性要求设置緩存存储器(即动态 緩存模块) 的数据量阔值, WAPI业务的实时性要求越高, 緩存存储器的数 据量阔值越低。 例如, 对于需进行流媒体播放的 WAPI业务, 数据传输的实 时性要求很高, 用户可将緩存存储器的数据量阔值设置为很小, 或者, 直接 设置为 0即不对此 WAPI业务数据进行緩存, 直接通过处理器内部的小容量 RAM进行数据緩冲。 对于需大量下载文件包且不需关注下载内容的 WAPI 业务, 用户可将緩存存储器的数据量阔值设置为很大。
如图 3所示, 降低 WAPI移动终端功耗的方法包括:
步骤 301 , 移动终端与 WAPI网络的无线访问节点之间建立通信连接, 进行数据下载;
步骤 302 , WAPI移动终端将接收的 WAPI业务数据緩存至动态緩存模块; 在对 WAPI数据进行緩存过程中, WAPI移动终端的处理器模块不处理緩存 的 WAPI数据;
在对 WAPI数据进行緩存过程中, 处理器判断当前除了 WAPI业务外无 其他优先级高于 WAPI业务的任务运行, 处理器进入睡眠或低功耗状态; 处 理器判断当前除了 WAPI的无线通信外还有其它他优先级高于 WAPI业务的 任务运行, 则处理器处理此优先级高于 WAPI业务的任务。
步骤 303 , 緩存的 WAPI数据累积达到 WAPI移动终端设置的数据量阔 值时, WAPI移动终端的处理器处理緩存的 WAPI业务数据;
緩存的 WAPI数据累积达到 WAPI移动终端设置的数据量阔值, 动态緩 存模块向处理器发送触发消息时, 如果处理器正处于睡眠状态, 则处理器退 出睡眠状态, 将动态緩存模块内的 WAPI数据搬移到存储模块; 如果处理器 正在处理其他优先级高于 WAPI业务的任务, 则处理器处理完此任务后再将 动态緩存模块内的 WAPI数据搬移到存储模块, 或者, 处理器收到触发消息 后, 暂停此任务的处理, 将动态緩存模块内的 WAPI数据搬移到存储模块。
步骤 304, 处理器判断 WAPI业务数据是否接收完毕, 如果是, 流程结 束, 否则, 转到步骤 302, 继续接收 WAPI业务数据。
通过上述方法, 如果用户通过 WAPI进行大流量数据下载且实时性不高 的 WAPI业务时, 处理器就没有必要一直监控和执行数据的下载工作, 而是 将 WAPI业务数据緩存在动态緩存模块中, 緩冲区中存储的数据达到一定值 时, 处理器再将其搬移动存储空间, 而且将 WAPI业务数据緩存的过程中, 处理器不对緩存的数据进行监控和处理, 这样在 WAPI数据緩存的耗时过程 中, 处理器不需对 WAPI业务耗费处理能力, 从而节省电量; 尤其是在下载 的 WAPI业务数据量较大, 下载时间耗时较长的情况下, 效果尤为明显。
下面结合附图进一步详细说明本发明的具体实施例。
如图 4所示, 结合图 2, 移动终端的动态緩存模块 105是一 FPGA芯片, WAPI移动终端处理 WAPI业务数据的方法包括:
步骤 401 , 用户根据自己的应用需求通过移动终端的人机交互设备 ( MMI )根据 WAPI业务的实时性要求设置 FPGA的緩冲存储区的数据容量, 设置的值通过移动终端的用户接口模块 102输入到处理器模块 101的寄存器 中;
例如, WAPI业务的实时性要求很高时, 可设置 FPGA的数据容量为 0,
WAPI 业务的实时性低, 用户为了移动终端最大限度的节省电力, 可以将 FPGA的数据容量设置到緩存存储器的最大容量。
步骤 402, FPGA根据处理器模块 101寄存器中的设置值对 FPGA的緩 冲存储区的容量进行设置;
步骤 403 , WAPI通信模块 103与 WAPI网络的无线访问节点之间建立通 信连接, 用户通过移动终端进行数据下载;
步骤 404, 处理器模块 101判断当前除了 WAPI通信模块 103在进行无 线数据传输外是否有其他优先级高于 WAPI业务的任务正在运行, 如果是执 行步骤 406, 否则执行步骤 405;
步骤 405, 处理器模块 101进入睡眠或低功耗模式, 等待高优先级业务 的执行和外部中断的唤醒;
步骤 406, 移动终端的 WAPI通信模块 103将接收到的下载数据緩存到 动态緩存模块 105的 RAM中;
步骤 407, FPGA的 RAM中存储的数据容量达到用户设置的容量阔值时, 产生中断输入到处理器模块 101中;
步骤 408, 如果处理器模块 101处于睡眠或低功耗模式下, 处理器模块 101退出睡眠或低功耗模式, 将 FPGA中的緩存数据搬移到存储模块 104中; 步骤 409, 处理器模块 101判断 WAPI通信模块 103与 WAPI网络的无 线访问节点之间的数据传输是否结束, 如果是执行步骤 410, 否则执行步骤 404;
步骤 410: 移动终端结束本次数据下载业务。
上述实现方式中, 由于处理模块和 WAPI通信模块之间的动态緩存模块 的设置,使处理器模块不需实时处理 WAPI通信模块发送的 WAPI业务数据。 上述方法中, 还设置了数据量阔值, 动态緩存模块緩存的 WAPI业务数据在 达到数据量阔值之前, 处理器模块可以不处理动态緩存模块中緩存的 WAPI 业务数据, 从而节省终端电力, 减少终端功耗。 但本发明并不限于上述一种 方式, 在其它实施例中, 处理器不必等到动态緩存模块緩存的 WAPI业务数 据在达到数据量阔值时, 才进行数据处理, 也可以在达到数据量阔值之前, 对緩存的数据进行一次或多次、 定时或不定时的间断性处理, 只要处理器不 需实时处理緩存数据即可, 本发明对具体实现的方法不作限制。
当然, 本发明还可有其他多种实施例, 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
工业实用性
本发明的方法中, 在 WAPI移动终端中增加动态緩存模块, 在移动终端 进行实时性要求低且数据量大的 WAPI数据下载操作时, 将数据緩存到动态 緩存模块的耗时过程中, 移动终端的处理器不需监控和处理动态緩存模块的 数据, 等到动态緩存模块中积累的数据达到系统设定数量时, 处理器再进行 统一处理, 这样可有效的降低移动终端的整机功耗, 减少处理器的工作量, 进一步节省移动终端的电量, 延长移动终端的连续使用时间。
