Abstract
一种延长移动通信终端的电池运行时间的方法。终端具有用于存储多个参考电平及其相应时隙循环指数的时隙循环指数表。如果设置时隙循环改变模式,则终端在规定的电池电平检查循环中检测电池电平并逐一把检测到的电池电平与参考电平进行比较,如果检测的电池电平高于所选参考电平之一时,终端把时隙循环指数设置到对应于选择的参考电平的值。当检测的电池电平超出参考电平范围时,终端把时隙循环指数设置到相应的最长的时隙循环。
Description
本发明涉及一种移动通信终端,特别是涉及一种用于延长移动通信终端的有限电池运行时间的方法。
移动用户能用其与其他用户通信的移动通信终端包括蜂窝状电话、PCS(个人通信服务)电话、CT-2(第二代无绳电话)等。移动通信终端在按照时隙循环指数(slot cycle index)确定的在规定的循环中搜索从基站接收到的信号。时隙循环指数在移动通信终端的生产过程中设置,用户可通过人机界面(MMI)功能改变时隙循环指数。通常,当用户处于不能够对电池充电多个小时的情况时,用户就使用MMI功能,以延长电池运行时间。但是,用户应当检测电池状态,每次都要用MMI功能控制时隙循环指数。此外,即使用户检测电池状态,他应当很好地理解时隙循环指数的概念,以便根据电池状态控制时隙循环指数。
因此本发明的目的是提供一种根据电池的剩余容量控制移动通信终端的时隙循环的方法。
为实现上述目的,提供一种用于延长移动通信终端的电池运行时间的方法。移动通信终端具有用于存储多个参考值及其相应的时隙循环指数的时隙循环指数表。当设置时隙循环改变模式时,终端在规定的电池电平检验循环内检测电池电平,并逐一地把检测到的电池电平与参考电平进行比较。如果检测到的电池电平高于所选择的参考电平之一时,终端把时隙循环指数设置到相对应选择的参考电平的值。
此外,当检测到的电池电平超出参考电平范围时,终端把时隙循环指数设置到相应最长的时隙循环。
参阅附图的详细说明,本发明的上述和其它目的、特征和优点将变得非常明显,附图中:
图1是应用本发明的移动通信终端中延长电池运行时间设备的方框图;和
图2是根据本发明的实施例说明用于延长移动通信终端的电池运行时间方法的流程图。
将参照附图描述本发明的优选实施例。
图1表示用于延长在移动通信终端中电池运行时间设备的方框图。参考图1,可再充电电池10提供工作电压给移动通信终端,及模数(A/D)变换器20把电池10的模拟电压信号变换为数字电压信号。中央处理单元(CPU)30根据存储在存储器40中的控制程序控制移动通信终端的整个工作。另外,CPU 30根据从A/D变换器20接收的电池10的数字电压信号设置时隙循环指数。存储器40存储CPU 30的控制程序和各种其它数据。特别是,存储器40具有用于存储时隙循环指数及其相应的参考电平的时隙循环指数表,如表1中所示。
<表1>
时隙循环指数 | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
参考电平(V) | 7.2 | 6.9 | 6.7 | 6.5 | 6.3 | 6.1 | 5.9 | 5.7 |
表1中,虽然表示为物理值,但参考电平是能用软件处理的数字数据。此外,由参考电平限定的7.2V和5.7V之间的电压范围意味着移动通信终端能正常工作的工作电压范围。
图2是根据本发明实施例用于延长移动通信终端的电池运行时间方法的流程图。在图2中,CPU 30在设置时隙循环指数时,每隔一定时间检测电池电平,并根据检测到的电池电平控制时隙循环指数。
参见图2,CPU 30在步骤210确定用户是否使用移动通信终端的键盘(未示出)已经设置时隙循环改变模式。如果确定用户已设置时隙循环改变模式,则在步骤212,CPU 30检查电池电平检验循环是否已经到来,以便每隔一定时间检查电池10的状态。如果在步骤212确定电池电平检验循环已经到来,则在步骤214,CPU 30通过读取从变换电池10的模拟电压信号的A/D变换器20输出的数字电压信号来检测电池10的电平。一旦检测电池电平,在步骤216,CPU 30设置计数值n为零,以便逐一地把检测到的电池电平与参考电平进行比较。
此后,在最初参考电平Lref_0的开始,CPU 30逐一地把检测到的电池电平与参考电平进行比较,以便在步骤218至226设置恰当的时隙循环指数。具体地讲,在步骤218,CPU 30把检测到的电池电平与对应于最短时隙循环的时隙循环指数(即,表1中的指数0)的最初参考电平Lref_0(即,表1中的7.2V)进行比较。作为比较结果,如果确定检测到的电池电平等于或低于最初的参考电平Lref_0,则在步骤220,CPU 30确定参考电平Lref_0是否是最低参考电平(即,表1中的5.7V)。如果确定参考电平Lref_0不是最低参考电平,则CPU 30把计数值n增加1,以在步骤222选择下一个参考电平Lref_1,然后返回到步骤218。然后,在步骤218,CPU 30把检测到的电池电平与参考电平Lref_1进行比较。作为比较结果,如果栓测到的电池电平高于参考电平Lref_1,则CPU 30从存储器40读出对应于参考电平Lref_1(即,表1中的6.9V)的时隙循环指数“1”,以便在步骤224,把时隙指数循环设置到“1”。然而,如果在步骤220确定参考电平Lref_n是最低参考电平,则CPU 30读出对应于最长时隙循环的时隙循环指数“7”,以便把时隙循环指数设置到“7”。
简单地说,如果在步骤218检测到的电池电平高于参考电平,则CPU 30在步骤224设置对应于参考电平的时隙循环指数。然而,如果检测到的电池电平等于或低于参考电平,CPU 30在步骤220和222将计数值n增加1,直到参考电平变得低于检测到的电池电平为止。
参见表1,如果检测电池电平是6.4V,则CPU 30把6.4V的检测到的电池电平与7.2V、6.9V、6.7V、6.5V和6.3V的参考电平Lref_0-Lref_4逐一进行比较。当6.4V的电池电平与6.3V的参考电平比较时,CPU 30确定电池电平高于参考电平Lref_4,并把时时隙循环指数设置到对应于6.3V的参考电平Lref_4的“4”。
应该明白的是,尽管上述实施例仅表明取决于电池电平检测循环的功能,但通过使步骤224或步骤226返回到步骤212,上述功能也可在每个电池电平检测循环重复进行。
如上所述,本发明的移动通信终端根据电池电平,通过控制时隙循环指数能够实现最小的电池消耗,于量,有助于有限的电池运行时间的延长。
尽管参考优选实施例表示和描述了本发明,但本领域的技术人员将会明白,在形式和细节上的各种变化将不会背离由所附权利要求限定的本发明的精神和范围。
