Description  translated from Chinese
用于限制内容使用的通信终端 For restricting content usage in a communication terminal

技术领域 FIELD

本发明涉及一种用于限制内容使用的技术。 The present invention relates to a technique for restricting use of the content.

背景技术 BACKGROUND

具有分组通信功能的传统移动电话可以从互联网上的服务器下载各种各样的内容,例如程序、图象数据和音乐数据等等。 Conventional mobile phone having a packet communication function can download a variety of content from a server on the Internet, such as program, image data and music data, and so on. 虽然在这些内容中有很多是可以自由使用的,但它们中的一些却由于内容提供商设置的使用限制而不能自由使用。 Although many of these contents can be freely used, but some of them but because of usage restriction set by the content provider can not be freely used. 例如,当在发货之前递送音乐数据用作广告或样品时,内容提供商最好能为该音乐数据设置一个使用期;从而允许听者在使用期之前播放它们,并禁止他在使用期之后播放。 After he use of allowing the listener to play them before use period, and to prohibit; for example, when delivering music data before shipment for advertising or sample, preferably a content provider for use of music data set play.

为了实现此目的,在2000年6月14日提交的日本专利申请公开No.2001-356966公开了一种方法。 To achieve this purpose, the Japanese Patent June 14, 2000 filed disclosure No.2001-356966 discloses a method. 在此方法中,当服务器发送一个内容到移动电话时,该服务器向该内容的标题加入表示该使用期的信息。 In this method, when the server sends a content to the mobile telephone, the server is added to the contents of the title indicates the use of the information. 通过这一信息,当移动电话播放该内容时,该移动电话确定由其时钟功能计下的时间是否超过了使用期。 With this information, when the mobile phone to play the content, the mobile phone is determined by the time count down clock function exceeds the usage period.

然而,移动电话的时间并非始终精确,因为移动电话的一些用户可能希望根据其自身需要来设置时间;例如,设置成比正确时间快五分钟。 However, the mobile phone's time is not always accurate, since some users may want a mobile phone according to their own needs to set the time; for example, set to the correct time faster than five minutes. 另外,当移动电话的用户将移动电话的时间设置成晚于正确时间,该用户就可以使用过期的内容。 In addition, when the user's mobile phone mobile phone later than the time set to the correct time, the user can use the content expires.

为了避免这一情况,可以使用下面的方法。 To avoid this situation, you can use the following method. 也就是说,当移动电话处理一个内容时,该移动电话从一个例如全球定位系统(GPS)卫星或时间服务器的外部设备接收一个基准时间,然后该移动电话将基准时间与内容的使用期进行比较。 That is, when the mobile telephone processes a content, the mobile phone from an external device such as the Global Positioning System (GPS) satellites or a time server receives a reference time, then the mobile-telephone will use the content with the reference time period is compared .

然而,上述方法具有一个缺点,就是:当移动电话处理该内容时,如果它位于地下或隧道中,它在那里不能从GPS卫星或时间服务器接收基准时间,它就无法正确地执行时间比较。 However, the above method has a disadvantage that: when the mobile telephone processes the content, if it is located underground or in a tunnel, it can not receive the reference time from GPS satellite or a time server, where it can not properly perform the time comparison. 此外,对于一种使用GPS卫星的方法,移动电话必须配有GPS接收机。 In addition, the use of GPS satellites for one kind of method, the mobile phone must be equipped with a GPS receiver. 同样,对于一种使用时间服务器的方法,它必须准备并维护服务器以及其它设施。 Similarly, for the method of using a time server approach, it must prepare and maintain servers and other facilities. 这两种方法都需要额外的开销。 Both methods require additional overhead.

非易失性存储器409存储用于移动电话40的应用程序以及从内容服务器10下载的内容和各种数据。 Non-volatile memory 409 stores a program for a mobile phone application program 40 and the download of the content from the content server 10 and various data. 在这些应用程序中,有一种程序,它根据时间限制信息来确定内容是否过期,或计算内容服务器10和计时单元404之间的时间差值。 In these applications, there is a program, which according to the time restriction information to determine whether the content expires, or 404 calculate the time difference between content server 10 and the timing unit.

图5是显示非易失性存储器409中的数据的数据配置的图。 Figure 5 is a non-volatile memory 409 of the data of the data configuration of FIG. 从内容服务器10下载的内容与内容ID相关并存入内容存储部分1021。 Associated and stored in the content storage section 1021 from the content server 10 downloads the content with the content ID. 同样,内容ID与时间差值信息TS、时间限制信息和时间复位标记相关并存入下载U/I文件存储部分1022。 Similarly, the content ID and time difference information TS, time constraints and time reset flag relevant information and store download U / I file storage section 1022.

时间差值信息TS是这样的信息,它表示当移动电话40接收到内容时由该移动电话40的计时单元404计下的时间与被加到该内容中的、内容服务器10发送内容时的发送时间之间的时间差值。 Time difference information TS is information that indicates the transmission time when the mobile telephone 40 receives the content from the mobile phone 40 under the terms of the timing unit 404 and is added to the content, the content server 10 transmits content of the time difference between the time. 时间差值信息TS被用于计算基准时间,以便确定该内容是否能使用。 Time difference information TS is used to calculate the reference time to determine whether the content can be used. 当由计时单元404计下的时间改变时,时间差值信息TS考虑该改变来进行更新。 When the time is determined by the timing of the change under section 404 meter time difference information TS consider this change to be updated.

时间限制信息是关于内容使用周期的信息,是从用于指示内容下载的网页的HTML文件中提取的。 Time restriction information is information about content usage cycle, is extracted from the HTML file for indicating the content download.

时间复位标记是一个用于确定由计时单元404计下的时间是否因为例如电源单元412用尽而被复位的标记,当复位时间尚未执行时,时间复位标记具有一个“0”值,而当复位时间被执行时,时间复位标记对于所有内容ID变为“1”。 Time Reset tag is a unit used to determine the time by counting under 404 dollars is because, for example the power supply unit 412 is reset exhausted mark, when the reset time is not yet implemented, time reset flag has a value "0", and when reset When the time is performed, all the time reset flag for content ID becomes "1."

此外,在非易失性存储器409内的程序中描述的是由时间差值信息TS表示的差值的精确度评估处理,这是通过使用时间复位标记执行的;下面将差值的精确度称为时间差值信息TS的精确度。 Further, in the program 409 described in the nonvolatile memory is to assess the accuracy of time difference information TS processing represented by the difference, which is performed by using the time reset flag; the accuracy of difference will be referred to for the accuracy of the time difference information TS. 在此处理中,该评估将如下所述;当时间复位标记具有值“0”时,精确度为高,当时间复位标记具有值“1”时,精确度为低。 In this process, the assessment will be described below; when the time reset flag has a value "0", the accuracy is high, when the time reset flag has a value "1", the accuracy is low. 另外,在此处理中,当存储于非易失性存储器409中的时间差值信息TS的精确度为低时,即使在给出处理具有使用期的内容的指示时,该内容的处理也不会被执行。 Further, in this process, when stored in non-volatile memory 409 time difference information TS accuracy is low, even when the content of the processing instruction is given with the use period, the processing of the content is not will be executed.

这一限制是用于促进具有使用期的内容的发布。 This limitation is released for the promotion of the use of the content has. 通常,发布内容的内容发布者假设:当发布内容时,具有使用期的内容在移动电话40上被正当地使用。 Typically, content publishers publish content hypothesis: When publishing content, content with the use of being rightly used on mobile phones 40. 然而,当由计时单元404计下的时间被复位时,由于该复位没有更新时间差值信息TS的内容,因而时间差值信息TS的精确度将变低。 However, when the time counted by the timer unit 404 is reset when the next, the content is not updated since the reset time difference information TS, and therefore the accuracy of time difference information TS will become low. 就是通过使用具有低精确度的时间差值信息TS限制内容使用时,也将有可能对使用进行不适当的限制;因此,不能使用上述假设。 Time difference information TS is through the use of a low accuracy when content usage restrictions, it will be possible to use also unduly limit; thus, can not use the above assumptions. 当不能使用上述假设时,就会有更少数量的、发布具有使用期的内容的内容发布者。 When not using the above assumptions, there will be fewer, and publishing content with the use of the content publishers. 因此,在此实施例中,时间差值信息TS的精确度被评估,并且根据这一评估,来限制内容使用。 Thus, in this embodiment, the accuracy of time difference information TS is evaluated and based on this assessment, to restrict the content usage.

在非易失性存储器409中,存储了时间设置标记。 In the non-volatile memory 409, the storage time setting mark. 时间设置标记是一个用于确定在移动电话40从工厂运出后时间是否已被用户设置的标记。 Time setting flag is a flag for determining in a mobile phone 40 after shipped from the factory has been set time whether user marks. 当运出移动电话40时,时间设置标记具有一个值“0”,并且,当时间被设置,时间设置标记被设置为值“1”。 When out of the mobile telephone 40, time setting tag having a value "0", and, when the time is set, time setting flag is set to the value "1."

【2.操作】接下来,将描述本实施例的操作。 [2. Operation] Next, the description of the operation of this embodiment.

【2.1.内容下载处理的操作】第一,用户使用移动电话40的输入单元402来指示万维网浏览器起动。 [2.1] Operation of first content download processing, the user input unit 40 using the mobile phone's web browser 402 to indicate the start. 接着,用户使用输入单元402输入一个URL来显示用于希望内容(在此例中,具有内容ID“C0001”的内容)的下载页面。 Next, the user uses the input unit 402 is used to input a URL to display the contents wish (in this case, having the content ID "C0001" content) of the download page. 通过这样,将一个具有URL的请求消息发送到内容服务器10。 By this, the request message is sent to the URL of a content server 10 will have.

内容服务器10的CPU101接收该请求消息,读出用于由请求消息中的URL指定的内容ID“C0001”的HTML文件,并发回移动电话40一个具有该HTML文件的响应消息。 Content server CPU101 10 receives the request message, read out the HTML file specified by the request for the URL in the message content ID "C0001", the mobile phone 40 sends back a response message with the HTML file.

移动电话40中的万维网浏览器翻译响应消息中的HTML文件,并在移动电话40的LCD单元405上显示用于下载页面的屏幕图象405a,如图6所示。 The mobile phone 40 Web browser translation HTML file in the response message, and on the LCD unit 40 of the mobile phone 405 displays a download page screen image 405a, as shown in Fig.

当用户点击下载页面的屏幕图象405a上的文本“商业1”时,则开始图7所示的内容下载处理。 When the user clicks on the download page of text screen image 405a on the "Business 1", then starts the content shown in the download process.

第一,移动电话40的CPU410确定待下载的内容是否包含一个使用期(步骤S101)。 First, the mobile phone CPU410 40 determines whether the content to be downloaded, including a use period (step S101). 更具体地说,CPU410查看从内容服务器10发送的HTML文件是否包含一个表示时间限制信息的关键字,例如用于在参量元素中的名称属性的值“周期”、“跨度”或“开始”。 More specifically, CPU410 View from the content server sends the HTML file 10 contains a time limit keyword information represents, for example, for the value "period" parameter element name of the property, "span" or "start."

当因为在HTML文件中没有表示时间限制信息的关键字,而确定待下载的内容不包含使用期时(步骤S101;否),CPU410发送一个用于下载内容的请求(下面称为下载请求),该内容由BTML文件中的目标元素中的内容ID“C0001”指定(步骤S103)。 When as in the HTML file does not represent the time limit keyword information, to be determined using the downloaded content does not contain a period (step S101; NO), CPU410 sends a request for downloading a content (hereinafter referred to as a download request), The contents of the file by BTML target element content ID "C0001" specified (step S103). 下载请求通过移动分组通信网络30和互联网20中继到内容服务器10。 Download request through the mobile packet communication network 30 and the Internet 20 to the content relay server 10.

内容服务器10从内容存储部分1021中读出具有下载请求中的URL指定的内容ID“C0001”的内容。 The content server 10 reads the content ID "C0001" has a download request URL specified content from the content storage section 1021. 并将其发送到移动电话40。 And sends it to the mobile phone 40.

移动电话40的CPU410接收从内容服务器10发送的内容,并使其与内容ID相关,以及将其存入非易失性存储器409(步骤S104)。 Mobile phone CPU410 40 receives content from the content server 10 sends, and correlates with the content ID, and the non-volatile memory 409 stores it (step S104).

另一方面,在本说明中,当在内容服务器10发送的HTML文件中用于内容ID“C0001”的名称属性的值为“周期”时,CPU410确定待下载的内容具有一个使用期(步骤S101;是)。 On the other hand, in this description, when the value "period" for content ID "C0001" in the HTML file sent by the content server 10 in the name of the property, CPU410 determines the content to be downloaded has a usage period (step S101 ; Yes). 另外,CPU410查看非易失性存储器409中的时间设置标记,并确定计时单元404是否以前被设置过(步骤S102)。 Further, CPU410 view nonvolatile memory 409 time flag is set, and timing unit 404 to determine whether it was previously set (step S102).

当由于时间设置标记具有一个值“0”,而确定时间以前未被设置时(步骤S102;否),CPU则因为时间没有设置而不能计算时间差值信息TS,并且因此,CPU410在移动电话40的LCD单元405上显示一条例如“请为下载此内容设置时间”的消息(步骤S105),并结束处理。 Since the time when the tag has a value set to "0", and determining the time was not previously set (step S102; NO), CPU time is not set as the time difference information can not be calculated TS, and therefore, CPU410 in the mobile phone 40 one example, "Please set the time to download this content" message (step S105) on the 405 LCD display unit, and the process ends.

在本说明中,当时间设置标记具有一个值“1”时,CPU410确定计时单元404以前被设置过(步骤S102;是),并以与步骤S107相同的方式发送一个内容的下载请求到内容服务器10(步骤S106)。 In this description, when the time set having a tag value "1", CPU410 determining timing unit 404 was previously set (step S102; Yes), and sends a content in the same manner as in step S107 the content downloading request to the server 10 (step S106).

内容服务器10的CPU101从硬盘102的内容存储部分1021中读出具有由下载请求中的URL指定的内容ID“C0001”的内容。 Content server CPU101 10 reads out the contents designated by the download request with the URL content ID "C0001" from the content storage section 1021 of hard disk 102.

CPU101然后读出一个当前时间(在本说明中,将使用“2002/05/0110:00:00”)。 CPU101 then read out a current time (in this note, we will use "2002/05/0110: 00: 00"). 然后,CPU101将当前时间(下面称为发送时间C0)“2002/05/01 10:00:00”加到内容的标题,并将其发送到移动电话40。 Then, CPU101 the current time (hereinafter referred to as transmission time C0) "2002/05/01 10:00:00" is added to the title of the content, and sends it to the mobile phone 40.

移动电话40的CPU410接收从内容服务器10发送的内容,并使其与内容ID“C0001”相关,以及将其存入非易失性存储器409(步骤S107)。 Mobile phone CPU410 40 receives content from the content server 10 transmits, and so the content ID "C0001" related, and it is stored in non-volatile memory 409 (step S107).

移动电话40的CPU410然后从内容的标题读出发送时间C0“2002/05/01 10:00:00”,还读出在接收内容的点上被保存在计时单元404的计时器中的时间T0(在本说明中,此时间为“2002/05/0109:58:00”)。 Mobile phone 40 CPU410 then read out the time to send time C0 "2002/05/01 10:00:00", also read out is stored in the timer unit 404 at the point of receiving content from the title of the content of T0 (In this description, this time for "2002/05/0109: 58: 00").

然后,CPU410计算时间差值信息TS,它表示内容服务器10与移动电话40之间的时间差值。 Then, CPU410 calculated time difference information TS, which represents the time difference between content server 10 and the mobile phone 40. 在本说明中,由于发送时间C0“2002/05/0110:00:00”-在接收内容的点上保存在计时单元404中的时间T0“2002/05/01 09:58:00”=两分钟,所以此时间差值为两分钟。 In this description, since the transmission time C0 "2002/05/0110: 00: 00" - time is stored in the timing unit 404 at the point of receiving the content of T0 "2002/05/01 09:58:00" = two minutes, so this time difference is two minutes.

如图5所示,CPU410使计算的时间差值信息TS“两分钟”与内容ID“C0001”相关,并将它们存入非易失性存储器409。 As shown in Figure 5, CPU410 so that the calculated time difference information TS "two minutes" and the content ID "C0001" correlation, and stores them in non-volatile memory 409. CPU410还将内容ID“C0001”与HTML文件中的时间限制信息(例如参量元素的名称属性的值“周期”和用于值“周期”的值属性的值)相关,以便显示用于下载页面的屏幕图象405a,并存储它们(步骤S108)。 CPU410 also content ID "C0001" and HTML files time limit information (such as the value of the name attribute of the element parameters "cycle" and the value for "cycle" of the value of the property) related to display the page for downloading screen image 405a, and store them (step S108).

在本说明中,通过互联网20和移动分组通信网络30的通信状态是令人满意的,因此,在由内容服务器10发送内容的时间和由移动电话40接收内容的时间之间几乎没有时间差值。 In this specification, via the Internet 20 and mobile packet communication network 30 communication state is satisfactory, and therefore, the time between the time of sending content by content server 10 and mobile telephone 40 receives content from almost no time difference . 作为结果,从时间差值信息TS可以正确地获得内容服务器10的计时单元103和404分别与移动电话40之间的时间差值。 As a result, the content server can be correctly obtained timing unit 10 103 and 404 from the time difference information TS, respectively, the time difference between the mobile telephone 40.

【2.2时间改变处理】下面,将描述在用户改变由移动电话40的计时单元404计下的时间的情况下,对时间差值信息TS进行的重算处理。 [2.2] time changing process will be described below in the case where the user changes the timing by the mobile phone 40 at the time count unit 404, the time difference information TS is recalculation processing.

当用户在移动电话40的输入单元402上执行一个特定按键操作,来指示开始设置时间设定时,CPU410读出计时单元404的计时器中保存的时间,并将它们显示在LCD单元405上。 When the user performs a specific operation on the key input unit 40 of the mobile phone 402, to indicate the start setting time setting, CPU410 reads the timer unit 404 to save time, and display them on the LCD unit 405. 接下来,用户用新时间T2(在此情况下,使用2002/05/07 10:00:00)覆盖在LCD单元405上显示的时间,并指示完成时间设定。 Next, the user with the new time T2 (in this case, use 2002/05/07 10:00:00) was coated on a 405 LCD time display unit, and indicating completion of time setting. 通过这样,CPU410将输入时间临时存入RAM408,并进行图8所示的时间改变处理。 By this way, CPU410 input time temporary stored RAM408, and the time change processing shown in Fig.

需要注意的是,当用户执行时间改变操作时,计时器持续增加保存在计时单元404的计时器中的时间的值,并且直到用户指示完成该时间设定,都有可能取消时间改变处理。 Note that when the user changes the execution time of the operation, the timer continues to increase the value stored in the timer unit 404 in the time, and the time until the user indicates that the setting is completed, are likely to cancel the time changing process.

如图8所示,CPU410从计时单元404的计时器读出一个时间T1(在本说明中,2002/05/08 12:00:00),还从RAM408中读出一个由用户使用输入单元402输入的时间T2“2002/05/07 10:00:00”(步骤S201)。 8, CPU410 reads out from the timer unit 404 in FIG time T1 (in this specification, 2002/05/08 12:00:00), and also reads out from RAM408 used by a user input unit 402 input time T2 "2002/05/07 10:00:00" (step S201).

然后,CPU410从非易失性存储器409中读出用于内容ID“C0001”的时间差值信息TS“两分钟”。 Then, CPU410 reads the time difference information TS for content ID "C0001" is "two minutes" from the nonvolatile memory 409. CPU410然后将此时间差值信息TS“两分钟”加到时间T1和时间T2之间的差值(T1-T2),此差值为“一天两小时”。 CPU410 then the difference between this time difference information TS "two minutes" is added to the time between T1 and the time T2 (T1-T2), this difference is "one day two hours." 其结果是“一天两小时两分钟”。 The result is "two hours a day, two minutes." CPU410使用这一结果来更新用于内容ID “C0001”的时间差值信息TS(步骤S202)。 This result is used to update the CPU410 for content ID "C0001" time difference information TS (step S202).

CPU410利用新近计算的值对对应于所有其它内容ID的其它时间差值信息TS作相同的处理。 CPU410 using a value corresponding to the newly calculated for all other content ID of the other time difference information TS for the same treatment. CPU410然后使用在RAM408中临时保存的时间T2来更新计时单元404的计时器。 CPU410 then used in RAM408 temporarily saved time T2 timing unit 404 to update the timer.

【2.3时间复位标记设置处理】接下来,将描述一个在移动电话40的计时单元404中计下的时间被复位时的处理。 [2.3 time reset flag setting process] Next, the processing time will be described in a mobile telephone 40 in the timing unit 404 is reset when the count of the next.

计时单元404中的时间被复位的情况可以是如此:当备用电池用尽和电能没被提供到计时单元404时,并且因此该计时单元404的计时器的内容消失。 Case timing unit 404 is reset time can be so: When the backup battery is dead and no power is supplied to the timing unit 404, and so the contents of the timer of the timer unit 404 disappear. 当时间被复位时,计时单元404的计时器的值变为“00/00/00 00:00:00”,且计时操作停止。 When the time is reset when the timer value timing unit 404 becomes "00/00/00 00:00:00", and the timer operation is stopped. 这个时间复位标记设置处理是按周期执行的,例如每秒钟一次。 This time reset flag setting process is performed in cycles, such as once per second.

图9是显示时间复位标记设置处理的流程图。 9 is a flowchart of the time reset flag setting process is displayed.

如此图中所示,CPU410确定由计时单元404计下的时间是否已经被复位(步骤S301)。 Shown in this figure, CPU410 determines the time counted by the timer unit 404 has already been under reset (step S301). 为了说明,CPU410查看计时单元404的计时器的值是否为“00/00/00 00:00:00”。 To illustrate, CPU410 view timing unit value of the timer 404 is "00/00/00 00:00:00."

当CPU410确定时间还没有被复位时(步骤S301;否),CPU410停止处理。 When the CPU410 determine the time has not been reset (step S301; NO), CPU410 stops processing.

另一方面,当计时单元404的计时器的值是“00/00/00 00:00:00”,并且CPU410确定时间已经被复位时(步骤S301;是),CPU410将存储于非易失性存储器409中的、与内容ID相关的所有时间复位标记的值改变(步骤S302)为值“1”,这表示时间已经被复位。 On the other hand, when the value of the timer count unit 404 is "00/00/00 00:00:00", and the CPU410 determines the time has been reset (step S301; yes), CPU410 stored in nonvolatile memory 409, the value is changed (step S302) with the content ID all the time reset flag is associated with the value "1", which indicates the time has been reset. 然后CPU410停止处理。 Then CPU410 stops processing.

【2.4.内容处理的过程】接下来,将描述移动电话40中的内容处理的过程。 [2.4] Next, process contents of the processing, the process will be described in the contents of processing the mobile telephone 40.

第一,用户使用移动电话40的输入单元402的按键来指示处理希望的内容(在本说明中,具有内容ID“C0001”的内容)。 First, the user using the key input unit 40 of the mobile phone 402 to indicate the treatment desired content (in this description, having the content ID "C0001" content). 通过这一指示,CPU410开始图10所示的内容处理的过程。 By this instruction, CPU410 10 starts the process content processing.

CPU410从非易失性存储器409中读出与内容ID“C0001”相关的时间差值信息TS“一天两小时两分钟”(步骤S401)。 CPU410 reads out the content ID "C0001" associated time difference information TS "one day two hours two minutes" (step S401) from the nonvolatile memory 409.

CPU410然后评估读出时间差值信息TS的精确度是高还是低(步骤S402)。 CPU410 then reads out the evaluation accuracy of time difference information TS is high or low (step S402).

为了说明,CPU410查看在非易失性存储器409中保存的时间复位标记。 To illustrate, CPU410 view in the nonvolatile memory 409 to save the time reset flag. 当时间复位标记的值为“1”表示时间已经被复位时,CPU410判定时间差值信息TS的精确度为低。 When the time reset flag has a value "1" indicates that time has been reset, CPU410 determines the accuracy of time difference information TS is low. 当时间复位标记的值为“0”表示时间还没有被复位时,CPU410判定时间差值信息TS的精确度为高。 When the time reset flag is "0" indicates that the time has not been reset, CPU410 determine the accuracy of the time difference information TS is high.

出现上述现象的原因如下。 The reason for the above phenomenon as follows. 当因为例如电源单元412中的备用电池用尽而复位由计时单元404计下的时间时,由计时单元404计下的时间被改变(复位),而不执行上述的“2.2时间改变处理”,并且由于电能没有被提供到计时单元404,所以计时操作停止,因此,时间差值信息TS的精确度变低。 Because, for example when the power supply unit 412 spare battery exhaustion reset time by counting cells under 404 dollars, the time by counting cells under 404 dollars is changed (reset) without performing the above "2.2 times change process" And because the power is not supplied to the timing unit 404, so the timing operation is stopped, and therefore, the accuracy of the time difference information TS becomes low.

如上所述,当读出时间差值信息TS的精确度被判定为低时(步骤S402;否),就不能正确地计算一个使用确定基准时间JT(下面进行描述)。 As described above, when the accuracy of the read-out time difference information TS is judged to be low (step S402; NO), one can not be properly calculated using the determined reference time JT (described below). 因此,CPU410在LCD单元405上显示一条例如“此内容不能被处理”的消息(步骤S408),并停止处理。 Thus, CPU410 is displayed on the LCD unit 405 a, for example "This content can not be processed" message (step S408), and stops processing.

另一方面,在这种情况下,用于内容ID“C0001”的复位标记的值为“0”。 On the other hand, in this case, for a value of "0" Content ID "C0001" of the reset flag. 也就是说,读出时间差值信息TS的精确度被判定为高(步骤S402;是)。 That is, the read accuracy of time difference information TS is judged to be high (step S402; Yes). 因此,CPU410向由计时单元404计下的当前时间MT(这里使用2002/05/07 12:00:00)加入时间差值信息TS“一天两小时两分钟”。 Therefore, CPU410 to the current time by counting cells under 404 meter MT (used here 2002/05/07 12:00:00) add time difference information TS "two hours two minutes a day." 通过这样,CPU410计算使用确定基准时间JT(在这种情况下,2002/05/08 14:02:00)(步骤S403)。 By this way, CPU410 calculated using the determined reference time JT (in this case, 2002/05/08 14:02:00) (step S403).

使用确定基准时间JT是通过从发送时间C0正确地计算时间、不受上述2.2.时间改变处理影响而获得的时间。 JT is determined using the reference time by calculating the correct time from the sending time C0, not above 2.2. Time to change the treatment on time obtained.

然后,CPU410从与内容ID“C0001”相关并被存入非易失性存储器409的时间限制信息中读出“2002/05/08/10/00”,这是使用该内容的时限,并将其改变为第二格式,为“2002/05/08 10:00:00”。 Then, CPU410 from the content ID "C0001" associated and stored in the nonvolatile memory 409 of the time limit information read out "2002/05/08/10/00", which is the time of using the content, and changes it to a second format, is "2002/05/08 10:00:00." 然后,CPU410比较此时限“2002/05/08 10:00:00”与使用确定基准时间JT“2002/05/08 14:02:00”(步骤S404)。 Then, CPU410 compare this time limit "2002/05/08 10:00:00" and used to determine the reference time JT "2002/05/08 14:02:00" (step S404).

在此情况下,使用确定基准时间JT“2002/05/08 14:02:00”在时限“2002/05/08 10:00:00”之外(步骤S405;否),因此CPU410在LCD单元405上显示一条例如“使用期期满”的消息(步骤S407),并停止内容处理的过程。 In this case, using the determined reference time JT "2002/05/08 14:02:00" outside the time limit "2002/05/08 10:00:00" (step S405; NO), and therefore in the LCD unit CPU410 an example "to use expired" message (step S407) on the display 405, and stops the process of content processing.

另一方面,当使用确定基准时间JT在时限之内时(步骤S405;是),CPU410处理该指定的内容(步骤S406)。 On the other hand, when the determination reference time JT is within the time limit (step S405; yes), CPU410 processes the specified content (step S406).

如所述,即使当由计时单元404计下的当前时间MT“2002/05/0712:00:00”在时限“2002/05/08 10:00:00”之内时,由于是否可能处理该内容的判定是根据计算的使用确定基准时间JT“2002/05/08 14:02:00”和时限“2002/05/08 10:00:00”之间的比较而做出的,所以有可能限制该内容的处理,而不受由计时单元404计下的当前时间MT的影响。 As mentioned, even when the current time by counting cells under the MT 404 meter within the "2002/05/0712: 00:00" in time "2002/05/08 10:00:00", due to the possibility of treating the determine the content is determined and made more "2002/05/08 10:00:00" between the reference time JT "2002/05/08 14:02:00" and limit the use of the calculation based on, it is possible restriction processing of the content, and the current time is not counted by the timer unit 404 under the influence of MT.

图11是显示如在各种时间和时间差值信息TS之间的上述处理的关系的表格。 Figure 11 is a table showing the relation of the above process between various time and time difference information TS is.

如图11所示,从下载内容的点到指示处理该内容的点的时间段为“T3-T0”。 11, from the point of downloading the content to the content indicating the processing point is the time period "T3-T0". 如果在此时间段内,内容服务器10正确地计时,那么当作出处理内容的指示时在内容服务器10上的时间就是当前时间CT=C0+T3-T0。 If during this period of time, the content server 10 timed correctly, then when giving directions processing content of 10 at the time on the content server is the current time CT = C0 + T3-T0.

同样,当作出处理该内容的指示时的时间差值信息TS将是TS=(C0-T0)+(T1-T2)。 Similarly, when giving directions to process the contents of the time difference information TS will be TS = (C0-T0) + (T1-T2). 另外,计时单元404的当前时间MT将是MT=T3+(T2-T1)。 In addition, the current time timing unit 404 will be MT MT = T3 + (T2-T1). 从这些,使用确定基准时间JT将是JT=MT+TS={T3+(T2-T1)}+{(C0-T0)+(T1-T2)}=C0+T3-T0。 From these, using the determined reference time JT will be JT = MT + TS = {T3 + (T2-T1)} + {(C0-T0) + (T1-T2)} = C0 + T3-T0. 这匹配于内容服务器10的当前时间CT。 This matches the current time, the content server 10 CT.

如所述,使用确定基准时间JT和时间限制信息之间的比较使得能够以一种如在从内容服务器10发送内容的点上希望的方式对内容使用进行限制。 As described, using the determined reference time JT and time restriction makes it possible to compare A from the content server 10 transmits the content of the point in a desired manner to restrict content usage information between.

同样,当不太可能以在发送内容的点上希望的方式来限制内容使用时,可能拒绝内容的下载或处理。 Similarly, when it is unlikely that at the point of sending the content desired manner to restrict content usage, it may refuse to download or processing of content. 这是例如当时间未在计时单元404中设置时,以及当存储于非易失性存储器409中的时间差值信息TS的精确度被判定为低时。 This is for example when time is not set when the timing unit 404, and stored in the nonvolatile memory when the accuracy of time difference information TS 409 is determined to be low.

如所述,按照本实施例,基于使用确定基准时间JT,以及不受该移动终端40的计时单元404所计下的时间或者通信环境的影响,有可能确定是否可能处理从内容服务器10下载到移动终端40上的内容。 As described, according to this embodiment, to determine the impact on the use of the reference time JT, and without the mobile terminal 40 of the timing unit 404 of the counted time or under a communication environment, it is possible to determine whether the content may be downloaded from the processing server 10 to content on the mobile terminal 40.

【3.修改】如所述,本发明的实施例已经被描述。 [3] As described modifications, embodiments of the invention have been described. 然而,在前面描述的本发明的具体实施例是为了解释的目的而提供的,并可以在不偏离本发明精神的情况下进行修改。 However, the specific embodiments described in the foregoing the present invention is provided for illustrative purposes, and can be modified without departing from the spirit of the invention. 下面将描述一些修改。 The following will describe some modifications.

【3.1修改1】在上述实施例中,在由时间限制信息表示的时限之后,内容不被处理。 [3.1 Modification 1] In the above embodiment, after the time limit indicated by time restriction information, the content is not processed. 然而,有可能使内容在一个特定时限之前不能被处理。 However, it is possible to make the contents can not be processed until a specified time limit.

例如,可能事先从内容服务器10向多个移动电话发布音乐,这些音乐在一个特定时间之前不应被播放。 For example, release may advance from the content server 10 to a plurality of mobile telephone music, the music before a particular time should not be played. 通过这样,便可能防止内容服务器10在经过一个特定时间之后被加载来自移动电话40的下载请求。 By this way, it is possible to prevent content server 10 is loaded download request from the mobile phone 40 after a specific time after.

同样,可能将另两个更多的信息“开始时间”和“结束时间”加入时间限制信息,并允许控制该内容处理。 Similarly, the other two may be additional information, "Start Time" and "End Time" add time restriction information, and allows to control the content processing.

例如,当该内容是用于显示票务预订页面和发送预订数据的程序时,可能在“开始时间”之前和“结束时间”之后限制在移动电话40上的内容处理。 For example, when the content is a program for ticket reservation page and send booking data is displayed, possibly after before the "Start Time" and "End Time" restrict content processing on the mobile phone (40). 通过这样,使具有预订时间周期的票务预售成为可能。 By this way, the ticket sale has booked time period possible.

另外,通过将“开始时间”和“从开始时间起的时段”加入时间限制信息,就可能允许控制该内容处理。 In addition, through the "Start Time" and "From the start time period," adding time limit information, it is possible to allow the control of the content processing.

例如,当这被应用于上述订票时,在“开始时间”之前和“从开始时间起的时段”之后禁止内容处理。 For example, when it is applied to the above reservations, until after the "Start Time" and "From the start time of the period" prohibited content processing.

【3.2修改2】在上面的实施例中,如图5所示,一个显示内容ID、时间差值信息TS和时间限制信息之间关系的清单被存入非易失性存储器409。 [3.2] In the modification 2 in the above embodiment, as shown in Figure 5, a display content ID, time difference information TS and time restriction information list is stored in the relationship between the non-volatile memory 409. 然而,这只是显示了存储具有关系的内容、时间差值信息TS和时间限制信息的想法。 However, this is only shows the contents of the storage with the relationship, the time difference information TS and time restriction information idea. 例如,可能使内容自身与时间差值信息TS和时间限制信息相关,并将它们存入非易失性存储器409。 For example, the content itself may limit the information relating to the time difference information TS and time, and stores them non-volatile memory 409.

【3.3修改3】在上面的实施例中,如图5所示,为每个内容存储时间差值信息。 [3.3] In modification 3 in the above embodiment, as shown in Fig 5, to store the time difference information for each content. 然而,可能通过使内容与内容服务器10相关来为每个内容服务器10存储时间差值信息TS。 However, the content may by associated with the content server 10 to the server 10 stores the time difference information TS for each content.

作为一种使内容与内容服务器10相关的方法,最好使用内容服务器10的IP“互联网协议”地址,如图12所示。 So that the content as a content server associated with the method of 10, preferably using the content server IP "Internet Protocol" address 10, as shown in Fig. 当从内容服务器10向移动电话40发送内容时,将此地址加到内容的标题。 When viewed from the content server 10 40 send content to mobile phones, this address is added to the contents of the title.

参考图13,将描述这种修改中的内容下载处理的操作。 Referring to Figure 13, the operation of this modification of content download processing is described.

步骤S501到S507是与图7所示步骤S101到S107相同的步骤。 Steps S501 to S507 are steps S101 to S107 shown in Fig. 7 the same step.

在步骤S508中,移动电话40的CPU410读取被写入内容标题的地址(在本情况下,“225.11.22.33”)。 In step S508, the mobile phone CPU410 40 reads the contents of the title is written in the address (in this case, "225.11.22.33"). 然后CPU410查看对于这个地址“225.11.22.33”在非易失性存储器409中是否有时间差值信息TS。 Then CPU410 view for this address "225.11.22.33" in non-volatile memory 409 whether there is time difference information TS.

当对于这个地址“225.11.22.33”在非易失性存储器409中存在时间差值信息TS时(步骤S508;是),CPU410停止处理。 As for this address "225.11.22.33" there is a time difference information TS in the nonvolatile memory 409 (step S508; yes), CPU410 stops processing.

当对于这个地址“225.11.22.33”在非易失性存储器409中不存在时间差值信息TS时(步骤S508;否),CPU410读取被写入内容的标题中的内容服务器的发送时间C0“2002/05/01 10:00:00”,以及用于下载页面的屏幕图象405a的HTML文件中的时间限制信息。 When for this address "225.11.22.33" no time difference information TS in the nonvolatile memory 409 (Step S508; NO), CPU410 reads the contents of the transmission time is written to the header of the content server C0 " 2002/05/01 10:00:00 ", and the screen image to download a page of HTML files 405a time limit information.

然后,CPU410使内容ID与时间限制信息、时间复位标记“0”和一个地址“225.11.22.33”相关,并将它们存入非易失性存储器409。 Then, CPU410 so that the content ID with time restriction information, time reset flag to "0" and an address "225.11.22.33" correlation, and stores them in non-volatile memory 409.

另外,CPU410读出在接收该内容时保存在计时单元404的计时器中的时间(在本说明中,“2002/05/01 09:58:00”)。 In addition, CPU410 readout time when receiving the content stored in the timer unit 404 (in this description, "2002/05/01 09:58:00"). 然后CPU410计算表示内容服务器10与移动电话40之间时间差值的时间差值信息TS(即,内容服务器的发送时间C0“2002/05/01 10:00:00”-由计时单元在接收该内容的点上计下的时间T0“2002/05/01 09:58:00”;其结果为两分钟)。 Then CPU410 calculate time difference information TS represents the time between the content server 10 and the mobile phone 40 the difference (i.e., transmission time content server C0 "2002/05/01 10:00:00" - by a timing unit receiving the time point of the content of the counted T0 "2002/05/01 09:58:00"; the result is two minutes). CPU410然后使两分钟的时间差值信息与地址“225.11.22.33”相关,并将它们存入非易失性存储器409(步骤S509)。 CPU410 then two minutes of the time difference between information and address "225.11.22.33" relevant, and store them non-volatile memory 409 (step S509).

在上面的实施例中,在时间改变处理中,CPU410向存储于非易失性存储器409中的时间差值信息TS加入改变前后之间的时间差值。 In the above embodiment, when the time change processing, CPU410 to time difference information TS stored in the nonvolatile memory 409 is added to change the time difference between before and after. 在此修改中,改变前后之间的时间差值被加到为内容服务器10的每个地址存储的时间差值信息TS。 In this modification, the time difference between before and after the change is applied to each address for the content server 10 stores the time difference information TS.

在内容处理的过程中,在上面的实施例中,CPU410通过使用与被指示将被处理的内容ID相关的时间差值信息TS来计算使用确定基准时间JT。 In the process of content processing, in the above embodiments, the content CPU410 is instructed by using the ID to be processed associated time difference information TS is calculated using the determined reference time JT. 然而,在此修改中,使用确定基准时间JT是通过使用与内容ID相关的时间差值信息TS计算的(更具体地说,从内容ID获得一个地址,然后从该地址获得时间差值信息)。 However, in this modification, the use determination reference time JT by using the content ID associated with the calculated time difference information TS (more specifically, an address obtained from the content ID, then time difference information obtained from this address) .

其它的操作与上面的实施例相同,因此,不给出相同的说明。 Other operation is the same with the above embodiment, therefore, the same description will not be given.

如所述,通过为每个内容服务器10存储时间差值信息TS,变得有可能相比于为每个内容存储时间差值信息TS,减小数据量。 As described, for each content server 10 by storing time difference information TS, it becomes possible for each content as compared to storing time difference information TS, reduce the amount of data.

然而,在此修改中,当内容服务器10的维护人员在设置内容服务器10的时间时发生了错误,则计时单元103由于这一错误而计下一个错的时间。 However, in this modification, when the content server maintenance staff of 10 at the time 10, set the content server error occurred, the timing unit 103 as a result of this error, the wrong count next time. 当移动电话40在错误的时段内从这个内容服务器10下载多个内容时,将会发生下面的缺陷。 When the mobile phone 40 in the wrong time to download more content from the content server 10, will take place the following defects.

即,当为错误之后下载的内容来计算使用确定基准时间JT时,会使用相对于错误之前下载的内容而计算的时间差值信息TS;因此,使用确定基准时间JT将变得不精确。 That is, when the error is then calculated using the downloaded content to determine when the reference time JT, using time difference information TS with respect to the content downloaded before the error calculated; therefore, used to determine the reference time JT will becomes inaccurate. 因此,应当在内容服务器10的时间精确度为高时使用这种修改。 Thus, the time should be the content server 10 is high accuracy using this modification.

【3.4修改4】在上面的实施例中,当内容服务器10发送内容时,内容服务器10向该内容加入由计时单元103计下的时间数据作为发送时间C0。 [4] in 3.4 modify the above embodiment, when content server 10 sends content, content server 10 is added to the contents of the time data counted by the timing unit 103 as a transmission time at C0. 然而,网关服务器31可以增加时间数据。 However, the gateway server 31 may add time data.

然而,在此情况中,当由内容服务器10的计时单元103计下的时间不同于由网关服务器31的计时单元计下的时间时,发送时间C0不能被认为是由内容服务器10发送内容的时间。 However, in this case, when the time is determined by timing unit 10 of the content server 103 is different from the counted time by the gateway server 31 of the counted clock means when the transmission time C0 can not be considered by the content server 10 transmits the contents of the time . 因此,由网关服务器31的计时单元计下的时间和由内容服务器10的计时单元103计下的时间必须同步。 Therefore, the time from the gateway server timing unit 31 and the counted time by the content server 10 under the terms of the timing unit 103 must be synchronized.

在此情况下,发送内容的方法如下。 In this case, sending the content as follows. 当内容服务器10通过网关服务器31向移动电话40发送内容时,内容服务器10的CPU101将用于增加时间信息的请求数据加到该内容,并将其发送。 When the content server 10 via the gateway server 31 transmits the content to the mobile phone 40, the content server CPU101 10 will be used to increase the time information added to the content data request, and sends it. 网关服务器31的CPU向内容加入由其计时单元计下的时间,并将其发送到移动电话40。 CPU 31 of the gateway server is added to the contents of the counted time by the timer unit, and sends it to the mobile phone 40.

通过这样,由网关服务器31加到该内容的时间可被认为是内容服务器10发送该内容时的时间。 By this, the gateway server 31 is added to the contents of the time may be considered to be the time the content server 10 transmits the content of.

【3.5修改5】在上面的实施例的内容下载处理的2.1.操作中,当判定该时间以前没有在计时单元404上被设置时,CPU410在移动电话40的LCD单元405上显示一条消息并结束处理。 [5] In the modification 3.5 2.1 The operation of the above embodiment of the content download processing, when it is determined that time has not been previously provided on the timing unit 404, CPU410 displays a message on the LCD unit 40 of the mobile phone 405 and ends deal with. 然而,其它操作也可以使用。 However, other operations may also be used. 例如,有可能在LCD单元405上显示一条消息和时间设置屏幕图象,以催促用户设置时间。 For example, it is possible to display a message and time setting screen image, to urge the user to set the time on the LCD unit 405.
