具有无线电设备和服务器的通信系统
技术领域
本发明涉及具有无线电设备和服务器的通信系统。分别地并且另外地，本发明涉及用于这样系统的无线电设备(如寻呼机)和服务器，无线电设备中具有称为“客户”软件的某类软件，和服务器中具有称为“服务器”软件的某类软件。诸如(但不限于)非对称公用双向寻呼系统的无线电通信系统连接无线电设备和服务器。
背景技术
商人、专业人员和普通消费者日益增加在移动中接入通信的需求。寻呼系统用于通信已变得非常普及，寻呼系统使用户能够携带轻量的、具有良好广域与建筑物内穿透的低费用设备。过去，寻呼系统具有只能单向通信的缺点，但近来摩托罗拉公司已提出“Reflex”非对称双向寻呼系统，使用户能应答输入消息。非对称系统尤其有益于发送给寻呼机的数据量超过期望从寻呼机发回的数据量。非对称系统特别适于发回标识“存储的”应答(诸如“OK”或“现在我不能马上回答”)的短确认或标记。
在非对称双向寻呼系统发展的同时，诸如“ARDIS”(商标)系统的对称双向数据系统已进行研制，使大量的数据能通过国家公众数据系统双向进行发送。
利用诸如由摩托罗拉公司制造的“Personal Messenger 100D”(商标)调制解调器的双向无线电调制解调器在专用e-mail(电子邮件)服务器与便携式计算机之间提供远程电子邮件(e-mail)连接是公知的。这样的安排表示在图1中。调制解调器106插入便携式计算机105的PCMCIA槽中，并在便携式计算机与其主机服务器之间建立(几乎类似于双向电话调制解调器链路的建立)至专用e-mail服务器的双向连接。这个连接是通过基站120与公用双向无线电网络130的公用网络服务器110进行。在这样的安排中，计算机就好像它利用无线局域网(LAN)连到服务器一样工作，除了连接慢(低带宽和高等待时间)之外。表示保持在主机服务器115上的“in”(输入)盒的整个内容的屏幕将出现在便携式计算机105上，包括消息类型、发送者姓名、接收时间等等。通过(利用鼠标或其他)选择特定消息，发送命令给服务器，使整个消息下载到便携式计算机上。
这样的双向无线电消息传送系统趋向于昂贵，这部分是因为提供(在给定时间上)主要专用于此用户的有效带宽无线电信道的费用。高费用的另一个原因是单独的调制解调器和便携式计算机。
发明内容

具体实施方式
参见图2，无线电通信系统表示为包括双向寻呼机形式的无线电设备200，最好是可从位于200North Point Center East Street 100，Alpharetta，Georgia，30202，美国的摩托罗拉公司购买的Page Writer(商标)寻呼机。无线电设备200与具有公用网络服务器203的公用非对称双向寻呼系统202的基站201通信。例如，提供商标Skytel的这样的系统。通过网关204连到公用网络服务器203的是专用网络服务器205，此服务器205称为“主机”服务器。术语“主机”表示某些通信设备与主机服务器205有关，即这些通信设备在那个主机服务器上进行登记。这样的通信设备包括LAN连接的终端(将在下面所述)并包括无线电设备200。主机服务器205具有下面更详细进行描述的虚拟客户软件206。
无线电设备200可以是具有无线电能力的双向寻呼机或便携式计算机，例如具有调制解调器的便携式计算机。网络202不必是非对称寻呼网络，但可选择地可以是对称无线电网络，诸如“ARDIS”网络。为了说明，仅示出基站201。网络202事实上具有分散在全国各处的许多基站。网络202表示为具有单个基站201，用于与无线电设备200进行双向通信，但是在网络202中有比发射机更多的接收机的可选择安排是可能的。公用网络服务器203与主机服务器205之间的网关204最好是互联网连接，但也能采用其他形式。此连接可以是专用连接或公用ISDN连接或模拟调制解调器连接。网关204甚至可以是网络202内的无线电连接。
参见图3，表示电子邮件(e-mail)消息的示例。此消息包括标题301和主体或文本302。此消息也表示为具有附件303，例如图象。在标题内，具有发送者字段310、日期与时间字段311和主题字段312，还具有在这里表示为字段313的地址字段。另一个字段一般是可利用的(但未在图3中示出)，这是CC字段，表示消息的其他接收者。附件303可包括在消息主体内，或在标题301中可以有信息字段，表示附件的存在和(可选地)附件的特性。
在使用无线电网络连接的现有技术e-mail系统中，在无线电装置上一般以列的形式综合消息的发送者、接收时间和主题的提要页形式显示标题301的信息是众所周知的。消息的文本302可能非常长是一个问题。在图3给出的示例中，有从Baby Bear(熊宝贝)给Mommy Bear(熊妈妈)的消息，但作为此消息的继续，有从Mommy Bear至Daddy Bear(熊爸爸)的早些时候的消息，多个消息一起堆积在长的文本中是非常普遍的。发送整个消息给无线电设备可能导致大量的和不必要的使用有限的与宝贵的无线电信道容量。另外，在图3中示出嵌入文本302的主体中的图象的附件303，附件通常甚至比它们所嵌入的文本更大。例如，图象代表非常大的数据文件。消息的接收者可能不需要附件或可能没有观看附件的能力。
诸如图3所示的消息的消息由图2所示系统处理的方式将进行描述，并且为了描述目的，结合图4描述图2的系统的具体细节。在下面的描述中，已结合图2所述的部分不再进行描述。
参见图4所示的无线电设备300，表示为具有(例如，利用都未示出的双工器或天线转换器)耦合到天线403的发射机401和接收机402。收发信机401和接收机402连接到最好是微处理器的控制电路405。控制电路405具有有关的存储器406并且具有预先存储的消息存储器407。存储器406和有关的消息存储器407实际上可能是相同的存储电路。也表示连接到控制电路405的是显示器408和键盘410。由于装置200的小尺寸，有必要严格限制键盘410。它最好具有用于字母表中每个字母的键，但可能限制到甚至比这更少的键。在装置200操作的所选模式中，键盘410所选的键，例如键411与412对应消息存储器407中所选的消息。
参见主机服务器205，具有形成主机服务器205的一部分的e-mail数据库430，并具有通过局域网435连到服务器205的计算机终端431、432和433。终端431至433和局域网435是任选的，但为了便于本发明的解释而包括这些组成部分。
主机服务器205具有与无线电设备200中的客户软件交互作用的虚拟客户软件206。此虚拟客户软件包括帐号表450，在此表450中e-mail服务器数据库430中的帐号或识别符与公用网络服务器203中的帐号或识别符相关。也包括在主机服务器205的虚拟客户软件中的是通知代理455、消息部分处理例行程序460和命令消息接收器465。在操作中，用户可使用终端431至433来生成e-mail消息和相互发送这些e-mail消息并发送e-mail消息给局域网435外面的其他接收者。如果消息要发送给其他接收者，则可由服务器205发送这些消息给互联网连接470。例如终端431的终端用户能查看显示所有其输入消息的提要信息的页和综合所有其输出消息的页。这些页的每一页表示消息的接收者(或发送者)、时间和主题标题。这个信息从e-mail数据库430中提供给终端。在数据库430中，有分配给每个用户的分区。利用用户帐号来识别数据库430的分区。因此，例如参见图3的消息，Daddy Bear，Mommy Bear和BabyBear在数据库430中均有帐号。每个帐号(在给出的示例中)仅利用帐号持有者名字来识别。这些帐号可称为e-mail帐号。如果例如终端431的终端用户希望查看其帐号中特定消息，他可选择那个消息，并且服务器205将从数据库430中传送包括整个标题与整个文本以及所有附件的整个消息给终端431。
现在参见无线电设备200，此设备几乎能以与终端431相同的方式动作，但在如下所述的功能和用户交互作用方面有某些不同。无线电设备200首先以Egglestor等人在1995年11月13日提交的并转让给本发明的受让人的美国专利申请08/557657中所述的方式与服务器205建立虚拟对话。那个申请引入在此作为参考。在建立虚拟对话过程中，设备200发送消息给服务器205，表示设备200希望接入的服务器数据库430中的e-mail帐号。在这样做的过程中，一个相关输入到帐号表450中，将e-mail帐号或识别符与寻呼机200的寻呼网络地址相关。
利用寻址网络地址的解释，在公用无线电网络202上登记的每个寻呼机或其他无线电设备200具有与公用网络服务器203有关的地址和数据库420中相应的帐号。帐号表450保持数据库430中e-mail帐号或识别符与数据库420中公用网络帐号之间相关的表。在这种方式中，当从指定的无线电设备200接收消息时，服务器205利用表示从中接收消息的无线电设备的识别接收此消息并能将那个无线电设备与合适的e-mail帐号相关。同样地，当e-mail寻址特定的帐号并需要发送给用户的无线电设备200上那个帐号的用户时，在帐号表450中识别无线电设备合适的地址并发送此消息给正确的无线电设备。
无线电设备200能生成存储在消息存储器407中的许多预识别的消息。这些消息中的一些消息是命令。能发送的命令包括“OK”、“Finish”(完成)和“Move”(移动)。
在操作中，消息部分处理例行程序460发送对应无线电设备200的数据库430中帐号的收件箱(in-box)中所选的消息标题表给无线电设备200。这些标题是短的，仅给出消息的发送者(图3的字段310)、日期或时间(字段311)和主题(字段312)或一部分主题字段。由各个用户在数据库430中建立规则，定义用户希望在观看其收件箱时接收多少和什么形式的标题信息。例如，用户能建立提供仅示出最后10个消息的规则或他能建立提供仅示出最近24小时内接收的消息的规则。对于每个消息，对发送给无线电设备200的消息主体的文本量设置一个预定极限。
优选地，文本的最初几行是在收到观看命令时发送的所有内容。在这种方式中，网络202不被占用并且不会因为要发送e-mail消息的整个文本302而被滥用。同样地，设备200的存储器406(这是非常有限的)不被冗长的e-mail消息文本和附件拥塞。300个字符的限制是合适的限制。
如果用户200需要更多的消息，则可按下另一个按钮(或重复按先前的按钮)，使另一个命令(例如，命令“Move”)发送给服务器205，使文本的接下来的几行发送给无线电设备200。以这种方式，用户可能继续接收消息的其他部分，直至他满意对他来说他已足够理解此消息。例如，消息可请求开会，并且用户能对此消息翻页，直至他已收到会议的时间、地点和日期，而且用户可能不希望再查阅此消息，直至他返回到他的办公室。当无线电设备200的用户返回到他的办公室时，他能利用终端431-433之一来读整个消息，将它打印和读任何附件。
现在参见图5，表示显示在无线电设备200的显示器408上的一系列屏幕画面示例。每个屏幕画面代表无线电设备的一种操作模式。因此，在无线电设备200的控制电路405中有对应图5中所示的9个屏幕画面中每个画面的软件例行程序。图5同样能表示为说明这些各自的软件例行程序之间转换的状态图。
在图5中，有在无线电设备200加电时显示给用户的最高级模式的打开屏幕500。作为屏幕500的加电与显示处理的功能，无线电设备200与公用无线电网络202的公用网络服务器203建立虚拟对话。屏幕500表示屏幕上5个按钮501-505。这5个按钮标记为“in-box(收件箱)”、“feed(馈送)”、“agent(代理)”、“user(用户)”和“exit(退出)”。优选地，5个屏幕上按钮501-505对应键盘410上的5个硬件按钮，诸如按钮411和412等。可选择地，显示器408可以具有数字化转换器，并且触针(stylus)可用于选择与启动屏幕上按钮。每一个按钮501-504代表表示在屏幕500右边的一种操作模式。这些操作模式是消息查看模式510、消息馈送模式520、消息代理模式530和用户喜好模式540。
在消息查看模式510中，显示的第一屏幕是收件箱屏幕550。这个屏幕具有4个屏幕上按钮551、552、553和554。这些铵钮对应命令“查看”、“删除”、“更新”和“完成”。屏幕550表示存储在服务器数据库430中的用户收件箱内容(图4)。这些信息以行的形式出现，以表示每个消息的发送者、接收日期和一部分主题字段的行的形式显示信息。通过(利用键板410或利用触针)启动按钮551，程序进入屏幕560。屏幕560显示消息的发送者、接收日期和主题，并且也显示消息文本的一部分。文本部分561仅是文本的几行。此部分561的大小或是预定的(例如，选择的以便装在显示器408内)或可由用户选择，定义消息部分的喜好长度。可设计其他安排来限制消息部分561的大小，例如，消息部分能在给定的字符或字符组上结束。例如，此消息能在出现第一或第二个回车符号时结束。
屏幕560具有对应命令“完成”、“回答”和“移动”的三个屏幕上按钮562、563和564。也能使另外的对应命令“删除”、“传送”和“回答”的按钮出现。
转到消息馈送模式520，利用按钮502启动的此模式的启动显示屏幕570。此屏幕具有对应命令“OK”和“取消”的屏幕上按钮571与572，屏幕570也具有一些模式选择按钮573。
参见消息代理模式530。此模式的启动显示消息代理屏幕580，具有“继续”与“取消”按钮581与582并且具有喜好选择按钮583。程序从屏幕580转到屏幕585(代理提要屏幕(agent summary screen))，具有代表命令“新增”、“编辑”、“删除”和“完成”的按钮586至589。
程序从代理提要屏幕585进到代理动作屏幕590，显示“完成”按钮591和“取消”按钮592，具有表示在屏幕590上的各种其他喜好按钮。可选择地，程序从屏幕585进到屏幕595，具有代表命令“OK”和“取消”的按钮596与597，屏幕595也具有用户喜好按钮598。
最后，用户喜好模式540显示具有入口字段611、612与613并具有用于命令“OK”与“取消”的命令按钮614与615的屏幕610。
在操作中，该应用打开屏幕500。用户能从此屏幕分别利用按钮501至504进到四个操作模式510至540之一。可选择地，通过按下按钮505“退出”，此应用退出并返回到与消息传送功能无关的缺省应用。在选择消息馈送模式520之后，显示屏幕570，用户能选择他希望的所有消息还是仅仅由用户代理发送的消息馈送给无线电设备200或者没有消息馈送给无线电设备200。
在选择前面两个喜好中的一个并启动按钮571之后，从用户设备200发送消息给服务器205，指示服务器205开始发送(馈送)消息给无线电设备200。从无线电设备200发送给服务器205的消息根据按钮573表示是要馈送收件箱所有消息还是仅仅馈送由代理(如下所述)识别的那些消息给无线电设备200。在命令消息接收机465上收到此消息之后，服务器205开始通过网关204并通过公用无线电网络202发送每一个所需消息的标题和文本部分。一旦发送，消息能在无线电设备200上进行查看，如屏幕550与560中所示的。
参见模式530，此模式通过按下503来启动并显示屏幕580，允许无线电设备200的用户定义一组(要存储在数据库430中的)规则，此组规则定义无线电设备200的用户希望接收的消息或消息形式或消息类型。因而，例如，选择按钮583能调用包含某些字的消息或省略某些字的消息。可按下按钮581来结束此程序，处理流程从屏幕580进到屏幕585，即代理提要屏幕。屏幕585综合要从服务器205发送给无线电设备200的消息。例如，可以利用发送者或利用主题关键字或利用紧急标志或利用主体(文本)来标识要选择的消息。通过启动按钮586，程序进到屏幕595，并且能输入新的关键字。要进行检索的字段利用喜好按钮598来选择并在字段600中输入关键字。在字段600中输入的关键字能使服务器205根据喜好按钮598中进行的选择在发送者字段、主题字段或主体字段中进行检索。
通过按下屏幕585上的编辑按钮587，显示代理动作屏幕590，请求服务器205在关键字一致时发送整个消息或只发送前面预定数量的字符或仅发送发送者或只发送发送者与主题。通过启动按钮591，给服务器205的命令消息接收机591发送一个消息，标识由用户定义的代理动作。这些代理动作作为规则存储在数据库430中并且此后定义从用户收件箱至无线电设备200的消息的过滤度(degree of filtering)。
通过启动用户喜好模式540，用户能在字段611中输入他的名字、在字段612中输入他的e-mail地址并在字段613中输入他的e-mail告警。通过按下按钮614，消息发送给服务器205并在命令消息接收机465上接收。此消息能完全改变无线电设备200的用户的e-mail地址，更新帐号表450来表示e-mail地址与寻呼机地址之间新的对应关系。这个特性允许无线电设备200的用户准许同伴用户输入e-mail地址并准许查看不同的e-mail帐号。
总之，图5已描述了如何利用存储在无线电设备200的控制器405中的软件程序操作的四种模式。消息查看模式允许无线电设备200的用户查看来自e-mail服务器205的e-mail消息。消息馈送模式520指示服务器205开始从e-mail服务器发送用户消息给无线电设备200。消息代理模式530允许设备200的用户远程建立存储在数据库430中的并与用户的e-mail帐号有关的一组过滤参数或规则。这组规则或过滤参数定义用户希望远程查看的消息类型或消息的特定方面。这个特性从允许用户选择要显示在无线电设备200上的消息这一方面讲具有非常灵活的优点。这个特性在具有非常有限的屏幕尺寸与存储器容量的设备中是最有用的，这是因为所有消息不加选择显示到无线电设备上可能不必要地占用存储器和占用屏幕，使用户恼怒。
最后，用户喜好模式540允许用户在服务器205中将自己的标识与想要查看哪个特定e-mail帐号联系起来，而不管无线电设备200在公用无线电网络202中的地址如何。
参见图6，示出描述与主机服务器205有关的无线电设备200操作的流程图。发生在无线电设备200的步骤表示在左边，而发生在主机服务器205的步骤表示在右边。此图左与右侧之间的箭头代表在无线电设备与服务器之间交换的消息(包括命令消息)。图6用图解的方式表示了这样一个过程：开始从主机服务器到无线电设备消息的馈送、读出一部分消息和请求同一消息的更多部分。类似于图6的图的流程图容易由本领域技术人员生成来说明上面结合图5所述的无线电设备与服务器之间的其他操作和交互作用。
具体参见图6，流程通过在无线电设备200与主机服务器205之间建立虚拟对话开始。这个虚拟对话的建立在步骤650在无线电设备中进行并在步骤651在主机服务器中进行。在开始虚拟对话之后，并在启动屏幕上键502之后，生成开始馈送的命令。这个命令(馈送命令653)发送给服务器并在步骤655中在服务器上接收。收到此命令之后，服务器在步骤656中发送标题信息，并且在步骤657中此信息在无线电设备上接收。
在屏幕550中启动“查看”按钮551之后，选择消息(步骤658)并显示在无线电设备的显示器上。流程进到步骤675。在步骤675，如果用户要求此消息的更多部分，他按下屏幕上按钮564并且流程从步骤675进到步骤680，使命令681生成并发送给服务器以请求此消息的更多部分。这个命令在步骤682接收并且在步骤684中递增计数器以识别此消息下一部分。如果在步骤686中没有更多的消息要发送，即计数器已到达消息末尾，则在步骤688中可能发送差错命令，表示没有更多的消息进行发送并且过程在690结束。另一方面，如果步骤686识别有更多的消息要发送，流程进到步骤664，并且格式化出局寻呼消息以便传送消息主体的下一部分，而且程序继续。
上面的描述仅利用示例给出，并且细节的修改可由本领域技术人员进行，而不脱离本发明的精神与范畴。
