具体实施方式

[0011] 图1示出了使用有蓝牙能力的移动电话以导航装置访问远程服务器的系统。

[0012] 系统100包括导航装置5,其被配置为通过移动电话1A-1B中可用的一个移动电话向远程因特网协议(IP)服务器15上传数据。软件8与软件18交换调谐通信,在至少每

5电话基础上(on at least aper-phone basis)调谐传输功率增益,接下来根据移动电话 1A-1B中当前可用的一个移动电话来使用已调谐的传输功率增益量。此在至少每电话基础上的调谐允许导航装置5与远程服务器15经由广泛的多种移动电话和无线电信网络来通信,而它们进而使针对导航装置5的通信机会最大化。

[0013] 为了理解这种调谐如何使导航装置5与服务器15通信的机会最大化,就要考虑如何根据所使用的是移动电话IA还是IB来有差异地处理从导航装置5到服务器15的通信。 起初,根据使用的是移动电话IA和IB中的哪一个,该通信将被不同的通信电路系统(诸如音码器20和21)处理。音码器20和21可以有差异地影响功率增益,例如通过将功率增益改变不同的量。此外,分别与移动电话IA和IB关联的不同的无线电信网络沈和27也可以具有不同的音码器22和23,其也可以有差异地影响信号。由于这些差异,在缺少在至少每电话基础上的调谐时,取决于音码器的哪个组合处理传输,接收机可能会接收到太弱或太强的信号。虽然对于服务器15和/或其带内信令(IBS)调制解调器19而言,检测到由太弱或太强的信号的恢复而导致的错误并且请求重传输是可能的,但这种重传输耗费时间并且仍可能会导致太弱或太强的信号。

[0014] 相对比,系统100在至少每电话基础上调谐功率增益,这允许来自导航装置5的传输29A在无错误或少错误的情况下被IBS 19接收和恢复,而无论导航装置5使用的是传输路径30A还是30B。换句话说,无论路径30A和30B之间有何差异,传输29B和29C都可以具有基本相似的功率增益。

[0015] 此在至少在每电话基础上的调谐意味着,可以根据具体的可用电话来设置传输功率增益,而不是仅仅调谐到可用电话的特定构造或原型(particular make or model)。属于同一构造或原型的两个移动电话也可以有差异地影响信号强度,因为这两个移动电话内的部件可以具有不同的运行特性。例如,电子部件通常被设定(rate)为在一个多值范围内工作。据此,这些电子部件中的一些在该范围的高端运行,而其他的在该范围的低端运行, 这可以导致属于同一原型的两个音码器在处理期间有差异地放大一个信号。例如,属于同一原型的两个电阻器可以表现出不同的电阻,而这些不同进而影响功率增益。出于此原因, 软件8和18在至少每电话基础上而不是在每原型基础上调谐传输功率。

[0016] 虽然软件8和18在至少每电话基础上调谐传输功率,但应注意到这种调谐在一些实施例中可以甚至更细致(granular)。稍后将参见图2更详细地讨论这一点。

[0017] 仍然参见图1,应理解系统100由此使针对导航装置5的上传机会最大化。换句话说,导航装置5不限于使用任何特定的指定电话与IP服务器15通信,而是当处于几乎任何支持蓝牙的移动电话的范围内时都可以访问服务器15。

[0018] 除了前一段落指出的之外,对于导航装置5优选的是利用一个移动电话向IP服务器15上传,而不论可用移动电话是否支持经由其无线电信网络的分组数据连接(packet data connection)。例如,所示出的移动电话1A-1B不支持经由无线电信网络沈和27的分组数据连接,但却可以被导航装置5用于IP网络访问,如下一段落中将描述的。

[0019] 出于此原因和其他原因,从导航装置5到服务器15的传输(包括稍后将更详细地讨论的调谐传输)被IBS调制解调器9调制,用于传输经过无线电信网络的语音信道。 IBS调制解调器9将所接收的数字数据调制成音频频率音调(audio frequency tones) 0 这些频率音调被选择以合成话语,从而所述频率音调将以小的衰减或衰落经过移动电话1A-1B中可用的一个移动电话的音码器20/21,以及可用无线电信网络沈/27中的任何音码器22/23(在网络26/27和服务器15之间的其他网络也可以运行音码器)。在被编码并调制成音频音调(audio tones)之前,所述数字数据优选地被格式化成一个或多个分组(packet)。一个分组格式化器(packet formatter)可以预先考虑,例如,在有效载荷 (payload)之前有一个头(header)和一个同步样式(sync pattern)。还可以添加纠错位 (error correction bits)、校验和(checksums)以及其他对分组的增强。然后导航装置5 可以经由用于语音数据的蓝牙连接来传输已IBS调制的通信^A,其经由无线电信网络的语音信道向前传送,经过任何中间网络(intervening networks)诸如IP网络观,被IBS调制解调器19接收和解调(恢复成比特流),然后最终被服务器15处理。

[0020] 应理解,对服务器15的可靠访问,或就此而言对任何远程网络的可靠访问,可以使得能够进行针对导航装置的广泛的多种应用。在导航装置5上的作为导航系统一部分的应用可以实时地获取基于位置的信息。例如,导航装置5可以获取经由GPS确定的关于当前位置附近的交通事故的实时信息。导航装置5也可以下载更新到内部导航数据库,例如将所存储的地图更新到关于新路线的信息。

[0021] 此外,使用此处描述的已调谐的传输,导航装置5上的任何其他类型的应用也可以设有远程存储的数据。这允许导航装置5的功能集(feature set)被扩展到与导航没有必然联系的其他应用。例如,导航装置5上的一个应用可以被用来获取股票报价或其他经由互联网可获得的信息。应理解,在导航装置5上运行的任何类型的应用也都有可能被用来获取对任何类型的网络的访问。

[0022] 应理解,此处描述的原理可以应用于任何有蓝牙能力的移动装置,不管所述装置是否具有任何导航能力。同样,无论在该装置和该移动电话之间的通信使用的是蓝牙还是其他无线协议,都可以应用上述原理。

[0023] 应理解,功率增益基于的是一个系统的信号输出与该系统的信号输入的比。当使用术语“传输功率增益”时,相关的系统是导航装置5 (或其他被配置为向服务器上传数据的装置)。当使用术语“接收功率增益”时,相关的系统是服务器15。

[0024] 可以使用用于调节增益的任何已知方法来对导航装置15调节发射功率增益。这可以包括调节导航装置15上的一个电路的要么输入级要么输出级中的放大器、可变电阻器或其他电路部件。

[0025] 图2示出了图1中所示的导航装置,以及该导航装置和用于调谐传输功率增益的远程服务器之间的交互作用。

[0026] 导航装置5包括待被软件8更新的表格38。表格38稍后被用来至少部分地基于可用移动电话来设置用于传输数据的功率增益。

[0027] 在该实施例中,导航装置5和移动电话31进行配对41,以建立在导航装置5和移动电话31之间的蓝牙连接。此蓝牙连接可以根据在美国专利申请12/752,911 "USING A BLUETOOTH CAPABLE MOBILE PHONE TO ACCESS A REMOTE NETWORK” 中描述的原理建立,该美国专利申请出于所有目的以全文引用方式纳入本文。而且,该配对可以被一个请求触发, 该请求来自在导航装置15上运行的应用,或来自导航装置15的用户接口。

[0028] 在配对期间,软件8获知针对移动电话31的蓝牙客户端ID。此蓝牙客户端ID是全球唯一的标识符,其将被用来在表格38中唯一地识别移动电话31。[0029] 移动电话31接收来自IP服务器15的会话发起(initiation)请求。导航装置5 处理该请求43,然后软件8使用一个机制来延迟会话发起。例如,软件8可以通过在确认 (acknowledgement)中使用比特设置44或通过用于延迟该会话发起的任何其他机制来导致该会话发起被延迟。软件18被配置为观察比特设置44,并据此延迟该会话发起。

[0030] 然后软件8通过使用IBS调制解调器9将所接收的数字数据调制成音频频率音调,来生成待被传输的测试数据45。这些频率音调被选择以合成话语,从而所述频率音调将以小的衰减或衰落经过任何中间音码器。在被编码并调制成音频音调之前,所述数字数据可以被格式化成一个或多个分组。一个分组格式化器可以预先考虑,例如,在有效载荷之前有一个头和一个同步样式。还可以添加纠错位、校验和以及其他对分组的增强。

[0031] 然后软件8将已调制的测试数据45传输多次,其中每次传输51处于一个不同的传输功率增益量。例如,测试数据45可以被传输三次,其中每次传输处于一个不同的功率增益量。

[0032] 在服务器15上,软件18接收所述传输并且确定一个接收功率增益。软件18发回应答52,以指示所确定的接收功率增益。

[0033] 在导航装置5上,软件8将用于所述测试数据的每次传输的接收功率增益关联到用于该传输的传输功率增益。此关联可以根据应答52中包括的信息而被执行。

[0034] 然后软件8分析接收功率增益量。此分析可以包括生成一个图表(graph),该图表在一个轴上包含接收功率增益并且在另一个轴上包含传输功率增益。如果使用该图表,则软件8可以将该图表上的点连起来以生成一个线图。然后,所生成的图表上的线可以被用来对传输功率增益进行插值(interpolate),这将在服务器15处生成期望的接收传输功率增益。显然,对接收功率增益的分析可以完全独立于图表而进行,但在任何情况下,该传输功率增益是基于对接收功率增益的分析而被插值的。已插值的传输功率增益将通常不同于在传输51中使用的传输功率增益,但有可能简单地选自在传输51中使用的传输功率增益量中的一个。

[0035] 软件8配置导航装置5,以使得传输将处于在分析期间识别的功率增益。这可以包括在导航装置5上设置一个蓝牙收发器,或控制导航装置5上的任何其他软件部件或硬件部件。据此,当出现延迟的会话发起61时,传输66处于所设置的传输功率增益。

[0036] 如前文所讨论,IBS调制解调器9被用来调制传输66的分组数据67。IBS调制解调器19从所接收的通信——其处于已调谐的接收功率增益——恢复数据。

[0037] 软件8还在表格38中将已插值的传输功率增益存储为与针对移动电话31的唯一的蓝牙客户端标识符相关联。表格38示出了在移动电话列和传输功率增益列中的条目 (entries),以示出这种关联。此后,当传输数据时,根据哪个移动电话被用于该传输,使用来自表格38的传输功率增益量。

[0038] 所示的表格38还包括如下可选列(optional column),所述可选列包括一个网络标识符,以指定在调谐期间使用的无线电信网络。此列可以被用来对所述调谐提供附加的细致度(additional granularity)。如前文所讨论,不同的无线电信网络利用了不同的音码器,这在至少一些情况下将对接收功率增益具有显著的影响。因此,在一些实施例中,所述调谐可以是在每电话和每网络基础上的。这在表格38中示出,其中蓝牙客户端ID C与两个不同的传输功率增益量(2. 5dB和3. IdB)相关联。[0039] 应理解,上述原理可以被用来向所述调谐添加甚至更多的细致度,例如该表格中更多的列。例如,依赖于音码器的当前利用的模式,同一电话/网络音码器组合可以与多个调谐功率增益量相关联。音码器可以运行在不同模式中(例如全速率和半速率),且取决于使用哪个模式,可以有差异地影响接收功率增益。据此,在一个实施例中,导航装置5确定了音码器的当前模式,并且基于当前模式为此特定的电话/网络组合在传输功率增益之间进行选择。其他可能的列包括:一天内的时间、介于无线电信网络和服务器15之间的其他网络的身份(identity)(其他网络诸如IP网络可以包括音码器),等等。

[0040] 此后,软件8可以将一个可用移动电话的蓝牙客户端ID (以及可能地其他变量,诸如网络ID)与表格38作比较,并且识别传输功率增益量。然后软件8使用已识别的功率增益量来设置该移动电话上的蓝牙收发器。

[0041] 一旦已设置传输功率增益,服务器15上的软件18就可以持续地监测所接收的来自该导航装置的传输。可能的是,接收功率增益可以“漂移(drift)”或者随时间以其他方式变化,尽管导航装置5对于同一移动电话继续使用同一传输设置。这可以因许多原因而发生,诸如:导航装置5和该可用移动电话在网络之间漫游、简单地改变到塔的距离、进入或离开功率节省模式,等等。在任一情况下,软件18可以在任何时间触发导航装置5上的软件8以发起一个新的调谐处理。

[0042] 软件18可以使用任何处理来确定何时需要一个新的调谐处理。在一个实施例中, 软件18持续地监测来自该导航装置的传输的接收功率增益,并且如果此接收功率增益落在一个阈值范围之外则触发一个新的调谐处理的发起。在另一个实施例中,软件18随时间监测传输错误率,并且如果此传输错误率超过一个阈值则触发一个新的调谐处理的发起。 由于传输错误可以与除了功率增益以外的其他因素有关,软件18可以进行一些小的纠错 (troubleshooting),以排除不太可能由来自此传输错误率的功率增益导致的传输错误。

[0043] 虽然在上述实施例中会话发起请求43是由服务器15发送的,但在其他实施例中导航装置5可以发送该会话发起请求并在该发送之前、之后或期间执行调谐。在这种实施例中,软件8可以不必在会话发起中导致延迟。

[0044] 图3示出了图1和图2中所示的导航装置如何调谐传输功率增益。

[0045] 在方框301中,该导航装置建立与一个移动电话的蓝牙连接,以与一个远程服务器通信。该蓝牙连接可以按照美国专利申请No. 12/752,911“USING A BLUETOOTH CAPABLE MOBILE PHONE TO ACCESS A REMOTE NETWORK” 中描述的来建立。

[0046] 在方框302中,该导航装置将针对该移动电话的唯一标识符(以及可能地其他属性,诸如网络标识符)与一个将移动电话关联到已调谐的传输功率增益量的表格作比较。 如果在菱形303中,该表格中存在针对该移动电话的条目,则在方框304A中,该导航装置根据针对该移动电话的已调谐的传输功率增益来设置蓝牙收发器。在方框305中,该导航装置发起一个与该远程服务器的会话,用于以所设置的传输功率增益上传数据。

[0047] 如果在菱形303中该表格中不存在该条目,则在方框304B中,所述导航装置延迟与所述远程服务器的会话的发起。在方框306中,所述导航装置将已接收的数字比特序列调制成一个音频信号(audio signal),其对于不同的比特值具有不同的频率音调,其中所述频率音调被选择以经过一个无线语音信道。在方框307中,所述导航装置使用不同的传输增益量来传输所述音频信号。[0048] 在方框308中,该导航装置收回一个对该传输的应答,该应答指示在远程服务器处的接收功率增益量。在方框309中,该导航装置通过分析该接收功率增益量来为该移动电话确定已调谐的传输功率增益。在方框310中,该导航装置在该表格中生成针对该移动电话的一个条目,以将该已调谐的传输功率增益关联到该移动装置。该过程然后返回到方框 304A。

[0049] 图4示出了图1和图2中所示的服务器如何调谐功率增益。

[0050] 在方框401中,该服务器接收一个音频信号的多个传输。在方框402中,该服务器为这些传输中的每一个确定一个接收功率增益,并且向一个导航装置发送一个识别该接收功率增益的通信。

[0051] 此后,在方框403中,该服务器接收一个具有已调谐的接收功率增益的传输。如果随后接收的传输具有一个阈值范围之外的接收功率增益,则在方框404中,该服务器可以用信号通知该导航装置执行一个新的调谐处理。该过程然后返回到方框401。

[0052] 本领域技术人员应明了,在不脱离本发明的基本原理的前提下,可以对上述实施方案的细节做出许多改变。因此,本发明的范围仅应由下列权利要求确定。

[0053] 上文讨论的大多数设备包括硬件和相关的软件。例如,典型的导航装置很可能包括一个或多个处理器以及在这些处理器上可执行以进行所描述的操作的软件。我们在普遍理解的意义上使用术语“软件”,以指代机器或处理器可用的程序(programs)或例程 (routines)(子例程、对象、插件,等等)以及数据。如所公知的,计算机程序通常包括存储在机器可读或计算机可读的存储介质中的指令。本发明的一些实施方案可以包括存储在机器可读或计算机可读的存储介质——诸如数字存储器——中的可执行程序或指令。我们并不暗示在任何特定实施方案中要求常规意义上的“计算机”。例如,各种处理器,嵌入式的或其他类型的,可以被用在设备——诸如此处描述的部件——中。

[0054] 用于存储软件的存储器也是公知的。在一些实施方案中,关联到给定处理器的存储器可以与该处理器被存储在同一物理装置中(“片上”存储器);例如,置于集成电路微处理器或类似物内的RAM或FLASH。在其他实施例中,该存储器包括一个独立装置,诸如外部盘存储器、存储阵列或便携式FLASH密钥卡(key fob)。在这种情况下,当该存储器和该数字处理器被操作性地连接在一起时,或者例如通过I/O端口、网络连接等彼此通信时,该存储器变得与该数字处理器“关联”,以使得该处理器可以读取存储在该存储器上的文件。所关联的存储器可以是设计为“只读”的(ROM),或者是借助于许可设置“只读”的,或者不是 “只读”的。其他实施例包括但不限于WORM、EPR0M、EEPR0M、FLASH,等等。这些技术常常是以固态半导体器件的形式实现的。其他存储器可包括移动部件,诸如常规旋转盘驱动器。所有这种存储器都是“机器可读的”或“计算机可读的”,并且可以被用来存储用于实现此处描述的功能的可执行指令。

[0055] “软件产品”指的是这样的存储器装置,其中一系列可执行指令以机器可读的形式存储,从而,对该软件产品有适当访问的合适的机器或处理器可以执行所述指令,从而进行由所述指令实现的处理。软件产品有时被用来发布软件。任何类型的机器可读存储器,包括但不限于上文概述的那些,可以被用来制作软件产品。也就是说,也已知的是,软件可以经由电子传输(“下载”)来发布,在此情况下,在该传输的传输端或接收端或这两端将存在相应的软件产品。[0056] 在本发明的一个优选实施方案中描述和示出本发明的原理之后,显然,在不脱离这种原理的前提下,本发明在布置和细节方面可以被做出修改。我们要求保护落入下列权利要求的精神和范围内的所有修改和变体。
