Description

一种手机时间校准方法
技术领域
本发明涉及通信设备的时间校准方法,特别是一种手机时间校准方法。
背景技术
通常,我们对手机上的时间进行校准,主要是通过人工调整方式,即通过钟表所显示的时间,进行手工调节。这种方式又慢,又不容易确保时间精确。
中国实用新型说明书(授权公告号:CN2497348Y)公开了一种时间校准控制装置,它包括接收机、信息处理及内部时钟电路以及显示电路;接收机接收同步到GPS时间的移动通信网信号或者寻呼信号;信息处理及内部时钟电路包括解码电路、微处理器和内部时钟,解码器与接收机相耦合,从接收到的系统信号中解码出系统信号所携带的GPS基准时间,并将GPS基准信号送入微处理器,微处理器根据GPS基准时间以及内部时钟的时钟信号,生成实际时间,并校准内部时钟;显示电路显示从微处理器中接收到的当前实际时间。虽然利用上述方式进行时间校准能够得到精确时间,但是若对手机时间校准也利用这种技术就需要GPS设备,相对而言成本较高。因此,我们亟需要一种方法,它不需要GPS设备也能得到较好的使用效果。
发明内容
本发明的目的是提供一种手机时间校准方法,主要解决现有的手机时间校准方法不能确保校准时间和实际时间没有误差的技术问题,主要借助于通讯系统短消息协议的规则来实现比较精确的时间校准。
为解决上述技术问题,本发明是这样实现的:
一种手机时间校准方法,遵循通信系统的短消息协议,其特征在于,它包括如下步骤:
①手机向自己发一条特殊短消息;
②记录下发送成功时手机的时间为x;
③记录收到此条短消息时手机时间时间为y;
④从此条短消息中提取短消息中心的标准时间为z;
⑤设置当前时间为z+(y-x)。
本发明藉由上述技术方案,具有如下技术效果:
本发明方法能有效、快速地获取正确的校准时间,,而且有效地遵循了现有的短信协议。
该方法可以广泛应用于Gsm、CDMA、TD-SCDMA等通信系统中。
附图说明
图1是本发明方法的流程图。
具体实施方式
请参阅图1,它是本发明手机时间校准方法的流程图。现举一Gsm网络中校正手机时间的实施例,它涉及到Gsm中短消息协议。如图1所示:在进行时间较准时,手机向自己发一条特殊短消息(如内容为“jzsj”),我们记录下发送成功时手机的时间为x,当我们收到此条短消息时手机时间时间为y,可从此条短消息中提取时间为z,最后,我们可设置当前时间(收到短消息)为z+(y-x)。本发明实现了在gsm网络中校正手机时间的方法,涉及到gsm中短消息协议。
其中:
·z为短消息中心(简称:sc)的时间,是一个准确的时间。当短消息中心收到短消息时会将其收到的时间填入将要发送到目标手机的短消息中,x时刻的准确时间与z相差在十秒左右;
·y-x为发送与接收的时间差;
·因此可设置收到此短消息的手机时间为z+(y-x)。
综上所述仅为本发明的较佳实施例而已,并非用来限定本发明的实施范围。即凡依本发明申请专利范围的内容所作的等效变化与修饰,都应为本发明的技术范畴。
