03141089.8 用于限制内容使用的通信终端 03141089.8 for restricting use of the content of communication terminal

技术领域 Technical 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 limiting the 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栽各种各样的内容,例如程序、图象数据和音乐数据等等。 Conventional mobile phone having a packet communication function can be tilted downward and crashed variety of content from a server on the Internet, such as programs, 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 is free to use, but some of them, but due to the use restrictions set by the content provider can not be used freely. 例如,当在发货之前递送音乐数据 For example, when the music data delivery prior to shipment

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。 When used as advertising or sample, preferably a content provider for the use of music data set; allowing the listener to play them before using period, and banned him from playing after use period.

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, 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 phone, the server is added to the contents of the title indicates that 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 play the content, the mobile phone determines the counted time by the clock function exceeds the lifetime.

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 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 mobile phone users will be mobile phone time is set to the correct time later, 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 That is, when dealing with a mobile phone content, such as the mobile phone from a global positioning system (GPS) satellite

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。 Or time external device server receives a reference time, then the mobile phone and the content of the reference time period of use for comparison.

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 drawback, is this: when the mobile phone deal with the content, if it is located underground or in a tunnel, it can not receive the reference time from GPS satellites or the time server, where it can not properly compare the execution time. 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 method of using the method of GPS satellites, the mobile phone must be equipped with GPS receivers. 同样,对于一种使用时间服务器的方法,它必须准务并维护服务器以及其它设施。 Similarly, for the method of using the time server approach, it must associate services and maintenance of 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 for storing a mobile phone application program 40 and the downloaded content from 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io 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 limit information to determine whether the content expires, or calculate the time difference between the content server 404 and timing unit io.

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 graph showing a non-volatile memory 409 a data configuration of the data in FIG. 从内容服务器10下栽的内容与内容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 Xiazai and 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 and time limit information associated reset flag and credited 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4 0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。 TS time difference information is information that indicates when the mobile phone 40 receives the content when the mobile phone 40 by the timing unit 404 meter time and under is added to the content, the content server 10 transmits content of the time difference between the transmission 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 counted by the counting unit 404 under the change, the time difference information TS consider the 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栽的网页的HTML文件中提取的, Time restriction information is information about the content life cycle, is extracted from the HTML file is used to indicate the content of the tilted downward and crashed,

时间复位标记是一个用于确定由计时单元4 04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"。 Reset time flag is a time determined by the timing unit for under 404 dollars is because, for example the power supply unit 412 is reset marks exhausted, when the reset time has not been performed, the time reset flag has a value "0", and when When the reset time is executed, the time reset flag for all content ID to "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 in the non-volatile memory is described in the accuracy of evaluation process by the time difference information TS indicates a difference, which is executed by using the time reset flag; accuracy of difference will be referred to the accuracy of 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 as follows; when the time reset flag has a value of "0", the accuracy is high, when the time reset flag has a value of "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。 In addition, in this process, when stored in non-volatile memory 409 time difference information TS accuracy is low, even if the processing instruction is given with the use of the content, not the content processing It 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 the mobile phone 40. 然而,当由计时单元404计下的时间被复位时,由 However, when the time counted by the timer unit 404 is reset under by

13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。 13 does not update the content of time difference information TS, and therefore the accuracy of time difference information TS will become lower. 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。 The time difference information TS is through the use of a low accuracy limit content use, also it will be possible to use undue restrictions; therefore, you 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 stores the 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 mark is used to determine when a mobile phone 40 time is shipped from the factory has been set user mark. 当运出移动电话40时,时间i殳置标记具有一个值"0",并且,当时间被设置,时间设置标记被设置为值"1"。 When the operation of a mobile phone 40, the time i set Shu tag has a value "0", and when the time is set, the time setting flag is set to the value "1." 【2.操作】 [2.

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 download processing content shown.

第一,移动电话40的CPU410确定待下栽的内容是否包含一个使用期(步骤SIOI)。 First, the mobile phone CPU410 40 to be tilted downward and crashed to determine whether the contents contain a usage period (step SIOI). 更具体地说,CPU410查看从内容服务器IO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 More specifically, CPU410 view HTML files are sent from the content server IO contains an express time limit information key, for example in

参量元素中的名称属性的值"周期"、"跨度"或"开始"。 The value of the parameter element name attribute of "cycle", "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发送一个用于下栽内容的请求(下面称为下栽请求),该内容由HTML文件中的目标元素中的内容ID "C0001"指定(步骤S103)。 Request, CPU410 sends an Xiazai content (hereinafter referred to as Xiazai request; when because the HTML file does not indicate the time limit keyword information, and determined to be downloaded content does not include the use of (NO in step S101) ), the contents of the HTML file in the target element content ID "C0001" designated (step S103). 下栽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。 Xiazai 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中读出具有下栽请求中的URL指定的内容ID "C0001"的内容。 The content server 10 reads out the content ID "C0001" has Xiazai 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 the content from the content server 10 to send, and correlates with the content ID, and store it in nonvolatile memory 409 (step S104).

另一方面,在本说明中,当在内容服务器IO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 specification, when the HTML file in the content server IO sent to a value of "cycle" Content ID "C0001" in the name of the property when, CPU410 determines the content to be downloaded has a lifetime (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)。 In addition, CPU410 view nonvolatile memory 409 time setting mark, and determine whether the timing unit 404 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。 Due to the time when the mark has a set value of "0", and the previously determined time is not set (step S102; NO), CPU time is not set because it can not calculate time difference information TS, and therefore, CPU410 mobile phone 40 one example, "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 the mark has a value of "1" is, CPU410 determines the timing unit 404 was previously set (step S102; Yes), and to send a content in the same manner as in step S107 download request to the content server 10 (step S106).

内容服务器10的CPU101从硬盘102的内容存储部分1021中读出具有由下栽请求中的URL指定的内容ID "C0001"的内容。 Content server CPU101 10 reads out the contents designated by the tilted downward and crashed with the URL request content ID "C0001" from the content storage section 102 in the hard disk 1021.

CPU101然后读出一个当前时间(在本说明中,将使用"2002/05/01 10: 00: 00")。 CPU101 then reads a current time (in this specification, the use of "2002/05/01 10:00: 00"). 然后,CPU101将当前时间(下面称为发送时间CO) "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 CO) "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IO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)。 CPU410 40 of the mobile phone receives the content transmitted from the content server IO, and reacted with the content ID "C0001" related, and it is stored in nonvolatile memory 409 (step S107).

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 period between sending the content by the content server 10 and received by the mobile phone 40 is almost no time difference between content . 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】 [2.2] change processing time

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。 Next, it will be described in the case of mobile phone users to change the timing unit 40 at 404 meter time, to the time difference information TS is recalculation process.

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 a user performs a specific operation on a mobile phone key input unit 40, 402, to indicate the start setting time setting, CPU410 reads the timer unit 404 to save time and displays 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) covering the time displayed on the 405 LCD unit, and instructions to complete the 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, CPU410 input time stored in the temporary RAM408, and the time changing process shown in FIG. 8.

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。 It should be noted that, when the user performs the time change operation, the timer continues to increase the value stored in the timer unit 404 of the time, and until the user instructions to complete the time setting, are likely to cancel time change process.

如图8所示,CPU410从计时单元404的计时器读出一个时间Tl (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 read from the timer unit 404 is shown in a time Tl (in this specification, 2002/05/08 12:00: 00), also read from RAM408 one used by the user input unit 402 Enter 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" in "two minutes" from the non-volatile memory 409. CPU410然后将此时间差值信息TS "两 CPU410 then this time difference information TS "two

16分钟"加到时间Tl和时间T2之间的差值(Tl-T2),此差值为"一天两小时"。其结果是"一天两小时两分钟"。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 )。 16 minutes' difference (Tl-T2) T2 is added to the time between Tl and time, this difference is "two hours a day." The result is that "two hours a day, two minutes" .CPU410 use the results to update with the 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 newly calculated using a value corresponding to all other content on the 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 use RAM408 temporarily save time T2 to update timing unit 404 timer. 【2. 3时间复位标记设置处理】 [2.3] time reset flag setting process

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。 Next, a description will deal with a mobile phone at the time of the timing unit 40 at 404 meter is reset when.

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: if the backup battery is dead and power is not being 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, the timer value of timer unit 404 becomes "00/00/00 00: 00: 00", and the timer operation is stopped. 这个时间复位标记i殳置处理是按周期执行的,例如每秒钟一次。 This time i reset flag Shu-processing is performed periodically, 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 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)。 As 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 the 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 determines 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 timing 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) and the content ID all the time reset flag related to 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】 [2.4. The content of the processing procedure]

接下来,将描述移动电话40中的内容处理的过程。 Next, the process will be described in a mobile phone 40 content processing.

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 uses the key input unit 40 of the mobile phone 402 to indicate desired content handling (in the present specification, with content ID "C0001" content). 通过这一指示,CPU410开始图IO所示的内容处理的过程。 With this indication, CPU410 starts the process content IO processing shown.

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 "—天两小时两分钟"(步骤S401)。 CPU410 reads out the content ID "C0001" related to the time difference information TS from the nonvolatile memory 409 "- day two hours two minutes" (step S401). 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 assess the accuracy of the read 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 non-volatile 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 is "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 time has not been reset, CPU410 determines the accuracy of time difference information TS is high.

出现上述现象的原因如下。 The reason for this phenomenon is 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 and the reset time backup battery is dead by a timing unit 404 meter down when the time counted by the timer unit 404 is changed under (reset) without performing the above "2.2 Time 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 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S"2;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)。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。 As described above, when the accuracy of the read time difference information TS is judged to be low (step S "2; NO), it can not correctly calculate a use determination reference time JT (described below) Thus, CPU410 in. LCD unit 405 displays an example "This content can not be processed," the message (step S408), and processing stops.

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" reset mark. 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 accuracy of the read 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 "—天两小时两分钟"。 Thus, CPU410 to the current time counted by the counting unit 404 under the MT (used here 2002/05/07 12:00: 00) added to the time difference information TS "- day two hours two minutes." 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, CPU410 calculated using the determined reference time JT (in this case, 2002/05/0814: 02: 00) (step S403).

使用确定基准时间JT是通过从发送时间CO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 transmission time CO, subject to the above 2. 2. Time to change the treatment on the obtained time.

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" relevant and is stored in non-volatile memory 409 of the time limit information read out "2002/05/08/10/00", which is the time limit to use the content, and it was changed 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 using the determined 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, to determine the reference time JT "2002/05/08 14: 02: 00" in the time limit "2002/05/08 10: 00: 00" outside (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; a), CPU410 processes the specified content (step S406).

如所述,即j吏当由计时单元404计下的当前时间MT "2002/05/07 12: 00: 00"在时限"2002/05/08 10: 00: 00"之内时,由于是否 As mentioned, namely j officials when the current time from the timer unit 404 meter MT under "2002/05/07 12:00: 00" within the time limit, "2002/05/08 10: 00:00" and, as if

可能处理该内容的判定是根据计算的使用确定基准时间n Determination of the content may be processed to determine the reference time n is calculated according to use

"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。 "2002/05/08 14:02: 00" and time "2002/05/08 10: 00: 00" and make a comparison between, it is possible to limit the processing of the content, regardless of the timing unit 404 meter MT under the influence of the current time.

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 graph showing the relationship between a table as described above between the various process time and the time difference information TS.

如图11所示,从下栽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 Xiazai content to the content of the instruction processing time point is "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 give directions when processing content at the time 10 of 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-(CO-TO) + (Tl-T2)。 Similarly, when making instructions to process the contents of the time difference information TS will be TS- (CO-TO) + (Tl-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 counting 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 - Tl ) } + { ( CO - TO ) + ( Tl - T2 ) } = CO + T3 - T0。 From these, the use of benchmarking time JT will be JT = MT + TS = {T3 + (T2 - Tl)} + {(CO - TO) + (Tl - T2)} = CO + 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n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 mentioned, the use of benchmarking time n and time constraints makes it possible to compare one as from the content server 10 sends the content to point the way you want to use to limit the information content 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 the unlikely to the point of sending the content the way you want to limit the content use may refuse to download or processing 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。 It is, for example when the time is not set when the timing unit 404, and stored in non-volatile 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n,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, the reference time is determined based on the use of n, and the impact of the mobile terminal 40 from the timing unit 404 at the time the count or the communication environment, it is possible to determine whether the processing may be downloaded from the content server 10 to content on the mobile terminal 40.

【3.修改】 [3. Modify]

如所述,本发明的实施例已经被描述。 As described, embodiments of the present 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 embodiment of the present invention described above is provided for illustrative purposes and may 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】 Amendment 1 [3.1]

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。 In the above embodiment, after the time information represented by the time limit, 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 before 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, it may advance release from the content server 10 to a plurality of mobile phone music, the music before a specific time should 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栽来自移动电话40的下载请求。 By this, it is possible to prevent content server 10 after a specific time after being applied planted download request from the mobile telephone 40.

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, it may be another two for more information on "Start Time" and "End Time" add time restriction information, and allows control of 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, before possibly after the "Start Time" and "End Time" to limit the 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 pre-sale period of time with a book as 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 time period from the start," added the time limit information, it is possible to allow 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, the before and after the "Start Time" and "From the start time of the period" prohibited content processing. 【3. 2修改2】 Amendment 2 [3.2]

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。 In the above embodiment, as shown in FIG. 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 just shows the contents of memory have a relationship, the time difference information TS and time constraints idea information. 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, it may make the information related to the content itself limit the time difference information TS and time, and store them non-volatile memory 409. 【3. 3修改3】 Amendment 3 [3.3]

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。 In the above embodiment, as shown in FIG. 5, the time difference information stored for each content. 然而,可能通过使内容与内容服务器IO相关来为每个内容服务器10 存储时间差值信息TS。 However, by making the content may be a content server IO associated with the server 10 to store 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。 As a content and make the content server 10 related methods, 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 the content server 10 sends the content to the mobile phone 40, 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 is described content download processing. 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CPIMIO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 CPIMIO 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 the nonvolatile memory 409 if 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),CPIM10停止处理。 As for the address "225. 11. 22.33" there is a time difference information TS in non-volatile memory 409 (step S508; a), CPIM10 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CO "2002/05/01 10: 00: 00",以及用于下栽页面的屏幕图象405a的HTML文件中的时间限制信息。 As for the address "33 225.11.22." There is no time difference information TS in non-volatile memory 409 (step S508; NO), CPU410 reads the contents of the transmission time of the title is written in the content server CO "2002/05/01 10: 00: 00", and a screen image Xiazai page's HTML file 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 enables content ID information and the time limit, the time reset flag to "0" and an address "225. 11. 22.33" relevant, 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 the present specification, "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CO "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TO "2002/05/01 09: 58: 00";其结果为两分钟)。 Then CPU410 calculated 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 CO "2002/05/01 10: 00: 00" - by a timing unit receiving the Content on point count at a time TO "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 make a two-minute time difference information and address "225.11.22. 33," related to the non-volatile memory and stores them 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, the processing time is changed, CPU410 to time difference information TS stored in non-volatile memory 409 is added in the time difference between before and after the change. 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, change the time difference between before and after the content server is added to each address 10 stores 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 by using the CPU410 is instructed to be processed and the ID of the 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, is used to determine the reference time JT by using the content ID associated with the calculated time difference information TS (more specifically, to get an address from a content ID, then time difference information obtained from the 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 as the above embodiments, therefore, does not give the same explanation. 如所述,通过为每个内容服务器IO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 by each content server IO 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 maintains a staff of 10 at the time of setting the server 10 an error occurs, the timing unit 103 due to the error count at a wrong time. 当移动电话40在错误的时段内从这个内容服务器10 下栽多个内容时,将会发生下面的缺陷。 When the mobile phone 40 in the wrong time period Xiazai more content from the content server 10, will take place the following defects.

即,当为错误之后下栽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 used to calculate the content Xiazai determining 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 Therefore, it should be in the content server 10

时间精确度为高时使用这种修改。 Time Accuracy is high when using this modification. 【3. 4修改4】 [4] 3.4 modification

在上面的实施例中,当内容服务器IO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。 In the above embodiment, when the content server IO sends content, the content server 10 is added to the contents of the time data from the timer count under section 103 as a transmission time C0. 然而,网关服务器31可以增加时间数据。 However, the gateway server 31 can increase the 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CO 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 counting unit 10 by the content server 103 is different from that at the time counted by the timer unit 31 of the gateway server when the count down, transmission time CO 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 counting unit 31 by the gateway server and the next time the count by the content server 10 under timing unit 103 meter must be synchronized.

在此情况下,发送内容的方法如下。 In this case, send the content is as follows. 当内容服务器IO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 sends the content to the mobile telephone IO 40 through the gateway server 31, the content server CPU101 10 will be used to increase the time information added to the contents of the request data, 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 time by counting cells under terms 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IO发送该内容时的时间。 By this, the gateway server 31 is added to the contents of the time period it can be considered the content server sends the content of the IO. 【3. 5修改5】 [5] 3.5 modification
