Description

包括一个GPS接收机的移动蜂窝电话
本发明涉及一个包括GPS接收机的移动蜂窝电话。
已知可为使得蜂窝电话网络的操作者能够确定呼叫进行的位置而使移动蜂窝电话配备一个GPS接收机。传统地，这通过由一个网络操作员经电话网络基站向电话作出位置请求而进行，并且响应于该请求，电话使其GPS接收机加电以确定其位置并且将与其位置对应的信息发送回该基站。
在这种电话中，GPS信号捕获和跟踪以及导航处理过程中的GPS接收机的功耗会比较高。所以，由于一个移动蜂窝电话通常只有有限的电池容量，因而最好该GPS接收机仅当需要时才加电。电池容量问题还因为审美和人类环境改造学原因而小型化移动电话(及其电池组件)的趋势而更加复杂。
对于紧急服务的紧急呼叫，当然期望呼叫的位置可以尽快获得。但是，从GPS接收机未接入最新星历数据的“冷起动”或者甚至更糟的情况下从GPS接收机未具有最新日历的“出厂冷起动”状态到首次确定(TTFF)的时间可以是30秒到5分钟之间的任何时间。
为了减少TTFF，GPS接收机可以配备有基站辅助手段，以便更快地获取GPS信号。这种辅助手段可能包括由基站向接收机供给用于校准GPS接收机中使用的本地振荡器的精确载频参考信号；用于最新卫星日历和星历数据的数据消息，可以根据该数据确定被考虑卫星的多普勒频移；以及当前的PRN码相位。借助这样的辅助手段，便可能只扫描一个已知由该目标PRN码占据的、变窄的频率和代码相位的范围，由此减少需要检验的代码实例的数目并且因此将实际代码捕获的时间减少至几秒。基站辅助手段在美国专利第5841396和5874914号中被进一步描述，它们被在此引入作为参考。
尽管已有上述改进，但是还期望进一步减少TTFF。这样做也是本发明的目的。
根据本发明，提供了一个移动蜂窝电话，它包括一个被安排用于与基站进行双向通信的通信发射机和接收机，以及一个GPS接收机，其特征在于该GPS接收机被安排成响应于电话已开机后用户和该移动电话之间的直接交互作用而加电。
这种GPS接收机能够立即开始处理GPS信号以便取回伪距离信息和确定它的当前位置，而不用等待呼叫连接或者从基站发送的位置请求。有利的是：GPS处理先于呼叫连接会减少信号干扰和淹没该GPS信号的风险，这种情况是由该移动单元的发射机发送编码话音或者其他数据到基站而引起的，并且也可能是由该移动单元的接收机接收基站应答而引起的。
而且，由于仅当需要时才加电，所以GPS接收机(以及因此该电话)的全部功耗保持相对较低。
特别地，但并非排它地，该GPS接收机可以被安排成响应于该用户进行例如到紧急服务的特殊呼叫而加电。
在这种安排中，电话对正进行的特殊呼叫的识别可以在用户例如通过敲打键盘或者使用语音识别来输入该呼叫电话号码时发生。
或者，识别可以在用户输入该呼叫电话号码的一位或者多位数字但非全部数字时发生。在这种情况下，该GPS接收机可能被安排成若该用户输入的号码偏离该呼叫电话号码则下电，这样可以节省功率。
作为对呼叫识别的可选方案，GPS接收机可能被安排成响应以下情况而加电：从蜂窝无线传输系统的基站接收的信号强度的改变，例如这指示该移动电话正移出口袋或者公文包；例如当由位于移动电话中的加速计检测时检测到该移动电话的移动；指示正由用户手持的电话温度或者施加到电话的压力的变化；或者拉回移动电话上的机盖，例如在移动电话带有保护键盘的滑动机盖的情况下收回该机盖，或者在“可翻转”移动电话的情况下翻转该机盖。GPS接收机可以被安排成响应可能由模糊逻辑确定的这些特征的组合而加电。
对于因特网使能的带有GPS接收机的移动电话，该GPS接收机可以被安排成响应用户选定一个特定网址而加电，例如一个与基于位置的业务关联的网址，由此在预见到来自该网址请求的情况下可确定呼叫位置。
通过例如参考附图，本发明的这些和其他方面通过参考在此后描述的实施方案将更清楚并且被说明，其中：
图1示意性地示出了根据本发明的移动蜂窝电话，并且
图2绘画性地示出了图1的移动蜂窝电话。
参考图1，示出的移动蜂窝电话100包括一个通信发射机(通信Tx)和接收机(通信Rx)102，它连接到一个通信天线101，并且由一个通信微处理器(通信μc)103控制以便与它所登记的基站BS通信。这种在蜂窝电话网络内用于双向通信的电话的设计和制造是公知的，所以这里不对未构成本发明部分的那些部分做详细描述。
除了移动电话的常规部件外，电话100还包括一个GPS接收机(GPSRx)105，它连接到一个GPS天线104，并且由一个GPS微处理器(GPSμc)106控制，以及还包括检测装置107，用于检测用户和该移动电话间的交互作用。响应于检测到这种交互作用，该GPS接收机105被加电，由此它可以通过GPS天线104接收NAVSTAR SPS GPS信号并且预处理它们，这典型地要进行无源带通滤波以便使带外RF干扰最小、预放大、下变频到中频(IF)以及模数变换。产生的数字化的IF信号保持被调制状态，仍然包含来自可用卫星的所有信息，并且被送入GPS微处理器106的存储器中，该微处理器与该GPS接收机105在相同时刻加电。然后为导出伪距离信息而获取和跟踪该GPS信号，根据该伪距离信息可以使用常规的导航算法来确定该移动电话的位置。这种用于GPS信号获取和跟踪的方法是公知的，例如，参见Artech House的GPSPrinciples and Applications(GPS原理和应用)(编辑，Kaplan)ISBN0-89006-793-7的第4章(GPS卫星信号特征)和第5章(GPS卫星信号捕获和跟踪)。该GPS微处理器105可以以通用微处理器的形式来实施，可选地与通信微处理器102共用，或者是嵌入在GPS专用集成电路(ASIC)中的微处理器。
图2中绘画性地显示了移动蜂窝电话100。翻盖200通过铰链201被附带于移动电话的机体202上，该机体上还装有键盘203，它在此实施方案中提供检测装置107，以及装有显示器204。在电话外侧还可见通信天线104及移动电话的翻盖205和机体206中的小孔，它们分别允许声波分别从位于翻盖200内的耳机扬声器(未示出)通过和到达位于移动电话的机体202内的话筒(未示出)。
当移动电话开机时，该移动蜂窝电话100的GPS接收机105和微处理器106保持不操作态，并且一直这样做，直到用户试图进行到紧急服务操作员的紧急呼叫。在用户键入“99”后，该GPS接收机和微处理器因预见到未来的来自该网络操作员对于该电话位置的请求而加电。
如果用户接着完成“999”紧急服务号码并且因此连接到紧急服务操作员，在接收到对电话位置的请求后，该所处位置由GPS微处理器105提供给该通信处理器103并且通过该电话所登记的基站被传送给操作员。或者，可以将伪距离信息提供给基站，以及在此(该移动蜂窝电话的远端)从此信息导出位置。
如果用户键入的号码偏离该紧急服务电话号码，例如用户键入997，则该GPS接收机105和微处理器106下电。作为基于用户键入一个紧急服务号码而加电的可选方案，该电话可能响应于翻开翻盖而加电，翻开翻盖指示该电话准备使用。
注意，英国的紧急服务的号码是“999”且“99”代表该号码的前两位数字。在美国，紧急服务操作员被称为公共安全应答点(PSAP)，其号码是“911”且因此对于美国而言，适于配置移动电话的等同的前两位数字是“91”。当然，该原理可同等地应用于有不同紧急呼叫电话号码的国家，所以参考英国来描述该原理并且号码“999”仅用于说明目的。
可选地，上面讨论的那类基站辅助手段可以被提供给GPS接收机以便该接收机更快地获取该GPS信号。
正如前面所述的，作为对键盘交互的替代方案，GPS接收机可以被安排成响应以下情况而加电：信号强度的改变、检测到的移动、温度或者压力的改变或者用户手持。在这些情况下，检测装置107可以分别包括合适的信号处理以确定信噪比、位于该移动电话中的加速计、温度传感器、压力传感器或者运动传感器或激励器。实际上，在本领域技术人员的头脑中会出现很多对这些部件的其他替代品。
同样，目前GPS最主要地是与带有时间和距离修正的导航系统(NAVSTAR)(一个由美国国防部开发和运行的全天候的、基于空间的导航系统)GPS关联，然而GPS所基于的一般原理是通用的且不只是限于NAVSTAR。因此，GPS是指任何包括处于不同位置的多个无线发射机和一个基于该无线发射机传输的到达时间而确定其位置的接收机的定位系统。
通过阅读本公开内容，对于本领域的技术人员来说其他修改是显而易见的，并且这些修改可能涉及到在GPS接收机及其部件部分的设计、制造和使用中已知的其他特征，所述特征可以用来代替或者添加到此处已经描述的特征。尽管在本申请中已经根据特征的特定组合提出了权利要求，但是应当理解本申请的公开内容的范围也显式地或者隐含地包括此处公开的任何新颖特征或者特征的任何新颖组合，不管它是否涉及当前在任何权利要求中要求的相同发明，以及是否如本发明一样地缓和了任何或者全部的相同问题。由此本申请人提请注意，在本申请或者任何另外的由此导出的申请的审理过程中，可以根据这些特征和/或这些特征的组合来提出新权利要求。
