Description

  The present invention relates to a mobile communication device and a server device, and more particularly to an improvement in technology for stopping radio wave transmission in a mobile phone.

  A radio wave off mode is known as a technique for stopping radio wave transmission in a mobile phone. The radio wave off mode is a mode in which only the transmission of radio waves is stopped while the power is on. In the radio off mode, the power is turned on but the transmission of radio waves is turned off, so you can enjoy installed games and manage schedules in areas where use of mobile phones is prohibited or restricted. It can be carried out. Further, the clock function of the mobile phone can be used instead of the wristwatch. Regarding the radio wave off mode, there are prior arts described in Patent Documents 1 and 2. For example, Patent Document 1 discloses a method for manually setting the radio wave off mode.

For example, Patent Document 2 discloses a method in which the radio wave off mode is set as a default when the power is turned on, and the user manually switches to the normal mode when transmitting / receiving a telephone or mail. . Here, the normal mode refers to a mode in which radio wave transmission / reception is activated.
Japanese Patent Laid-Open No. 11-225378 JP2003-134562

  However, in the method of manually setting the radio wave off mode as in Patent Document 1, there is a possibility that the user may forget to set in an area where the use of the mobile phone is prohibited. For example, in a train, if a passenger forgets to set the radio wave off mode and uses the schedule function or clock function of the mobile phone, the location registration etc. is performed even though the telephone call or mail transmission is not performed. Since the radio waves to be transmitted are sent to the base station, there is a possibility of inconvenience others.

  In order to solve this, it is conceivable to apply the technique described in Patent Document 2. The technique of Patent Document 2 is a technique for setting the radio wave off mode by default, and unnecessary radio wave transmission is reduced. The problem in Patent Document 2 is when the normal mode is set by making a phone call even once. In this case, since it is necessary to manually set the radio wave off mode in the train, forgetting to set the radio wave off mode still occurs.

  Accordingly, an object of the present invention is to provide a portable communication device that can reduce a user's forgetting to set a radio wave off mode in a train and realize a comfortable in-vehicle environment.

  In order to solve the above problems, a portable communication device according to the present invention accesses a server device via a network and obtains information from an access means for acquiring information and a first mode in which transmission / reception of radio waves is turned on. Mode transition means for performing the process of shifting to the second mode in which transmission is turned off or the process of shifting from the second mode to the first mode based on the acquired information.

  The portable communication device according to the present invention has the above-described configuration, so that when the user accesses the server device, the portable communication device shifts from the normal mode to the radio wave off mode. Even if the user forgets to switch to the radio wave off mode, as long as the server device is accessed, the user can reliably switch to the radio wave off mode. Can be reduced.

  The portable communication device further includes a memory and a clock unit that counts the current time. The access unit accesses the server device to acquire time information, and the time acquired by the browser. A writing unit for writing information to the memory, and the mode transition means performs the mode transition when the current time measured by the clock means coincides with the time indicated by the time information stored in the memory. You may let them. As a result, the transition to the radio wave off mode can be managed with the time information written in the memory, and the transition to the radio wave off mode is made when the current time matches with reference to the time information. It is not always necessary to set it immediately before desiring to shift to the radio wave off mode, and it can be set in advance.

  In addition, the browser has a parser unit that analyzes the content of a Web page provided by the server device and extracts a command described in an XML language, and the writing unit includes a command that is extracted In the case of a write command for writing time information in the memory, the time information may be written in the memory. As a result, when the web page is operated by the business operator side, the radio wave off mode can be set without depending on the morals of the user side. Furthermore, time information downloaded from a web page can be written to a mobile phone that already has a parser unit and a writing unit corresponding to the XML language for initial setting. In the present invention, as an additional configuration of the mobile phone, only a parser unit and a writing unit are required, so that it is possible to reduce forgetting to set the radio wave off mode without increasing the cost of the mobile phone. is there.

  Hereinafter, an embodiment of a mobile communication device according to the present invention will be described using a mobile phone as an example. FIG. 1 is a diagram showing a communication system necessary for connecting to the Internet with a mobile phone and browsing a Web page. The internal configuration of the mobile phone is also shown.

The web server 1 includes a providing unit 2 and a storage unit for storing web pages. Here, various services are information on the departure place, arrival place, departure time, arrival time, and vacant seats of each train on a web page managed by the railway company, and allow users to browse. is there. Furthermore, it is possible to make reservations for tickets.

The providing unit 2 transmits MMC (Mobile Management Command) that can be executed by the mobile phone 5 to the mobile phone 5 that has accessed a specific Web page installed on the Web server 1. Here, the MMC is a command string described in XML format, and the mobile phone 5 performs various settings by interpreting and executing the command string.
Next, the mobile phone 5 will be described. The cellular phone 5 includes an antenna 6, a transmission / reception unit 7, a power supply unit 8, a switch 9, and a non-communication function unit 10.

  The transmission / reception unit 7 performs a conversion process between the high frequency signal and the baseband signal and a transmission / reception process for the baseband signal. At the time of data reception, the high-frequency signal input from the antenna 6 is amplified, converted into a baseband signal, subjected to reception processing, digital data is obtained and output to the non-communication function unit 10. At the time of transmission, the baseband signal from the non-communication function unit 10 is converted into a high frequency signal, amplified and transmitted. The transmission / reception unit 7 has a function related to incoming / outgoing calls, transmission / reception of mail and Web, and a function of receiving control information from the base station. In the radio wave off mode, the functions of sending and receiving calls and sending and receiving mail and Web are stopped so that only control information from the base station can be received. This is to enable smooth communication and communication after canceling the radio wave off mode even when the user moves and the base station for communication changes.

The power supply unit 8 supplies the power generated here to the transmission / reception unit 7 and the non-communication function unit 10 via the switch 9.
The switch 9 switches whether to supply the power from the power supply unit 8 only to the non-communication function unit 10 or to the transmission / reception unit 7 and the non-communication function unit 10 in response to a signal from the non-communication function unit 10. . When it is on, power is supplied to the transmission / reception unit 7 and the non-communication function unit 10, and when it is off, power is supplied only to the non-communication function unit 10.

When it is off, the power supply is cut off only for functions related to incoming / outgoing calls and mail / web transmission / reception in the transmission / reception unit 7, and the function for receiving control information from the base station is a separate system. Electric power is supplied.
The non-communication function unit 10 includes a control unit 11, a display unit 15, a memory 16, a clock unit 17, and an operation unit 19. Functions that are not related to transmission / reception of radio waves, such as schedule management and games, are realized by the non-communication function unit 10. Subsequently, each component of the non-communication function unit 10 will be described.

The control unit 11 includes a CPU and a ROM. The CPU reads a program stored in the ROM and cooperates with hardware resources to function as a browser 12, a writing unit 14, and a mode transition unit 18. Fulfill.
The browser 12 is software that reads data described in HTML language, XML language, or the like. The content read here is displayed on the display unit 15 and used when browsing a web page installed on the web server 1. The browser 12 includes a parser unit 13 as shown in FIG.

The parser unit 13 extracts a command sequence described in XML format from the MMC transmitted from a page on the Web, and determines whether or not the extracted command sequence is executable by the mobile phone 5. Do.
The writing unit 14 performs writing to the memory 16 according to the command sequence extracted by the parser unit 13.

  Here, the parser unit 13 and the writing unit 14 are provided for accessing the initial setting server designated by the communication carrier after the purchase of the mobile phone 5 and writing the initial setting information in the memory 16. In the present embodiment, the MMC for accessing the railway company homepage and setting the radio wave off mode is received. An example of MMC obtained when accessing the railway company's Web page is shown in FIG.

  The parser unit 13 extracts a sentence between the tags <mmc mmcID ...> and </ mmc> as a command string. The statements described in the tag <method ... /> indicate individual commands. They are the command identifier id, the memory access command name, the reportstatus indicating the condition when responding to the server, the object specifying the write destination of the memory 16 in the mobile phone 5, the memory 16 includes a value indicating a value to be written. When name is "write", writing to volatile memory is indicated, and when "commit" is indicated, writing to nonvolatile memory is indicated.

  The display unit 15 is realized by a liquid crystal display or the like, and receives a signal from the control unit 11 and displays a web page using the browser 12. FIG. 4 is an example in which the railway company's web page is displayed on the display unit 15 and is a scene in which the web page is being browsed in order to reserve a train ticket for XX railway. The departure date, departure point, and arrival point have already been selected, and the departure time, arrival time, and train name of each corresponding train are displayed numerically as shown in FIG. It is indicated by ○ ×. Here, by selecting a train name and inputting personal information such as a name on the screen displayed at that time, a reservation confirmation screen as shown in FIG. 5 is displayed. When “OK” is clicked here, the screen in FIG. 6 is displayed prompting the user to select whether or not to set the radio wave off mode for the time period from the departure time to the arrival time. This is displayed by browsing the reservation confirmation screen shown in FIG. 5 and automatically downloading the MMC including the radio wave off mode setting command sequence and extracting it by the parser unit 13. When “Yes” is selected here, the writing unit 14 writes the date / time information related to the setting of the radio wave off mode in the memory 16 so that the setting of the radio wave off mode is registered, and the setting in the above time zone becomes valid. Then, the screen of FIG. 7 indicating that the radio wave off mode setting registration has been completed is displayed on the display unit 15. If "No" is selected here, the date and time information related to the radio wave off mode setting is not written in the memory 16, so the setting is not registered and the radio wave off mode setting in the above time zone is invalid. It becomes.

The memory 16 has a volatile memory and a nonvolatile memory. Volatile memory is DRAM, SRAM, or the like, which requires a power source for storing data, and the contents stored therein disappear when the power of the cellular phone 5 is turned off. This is used when processing is performed by the control unit 11 and data is temporarily stored.
The nonvolatile memory is an EEPROM or the like, and the contents stored therein are not lost even when the power of the mobile phone 5 is turned off. Therefore, when the radio wave off mode setting command sequence is written in the nonvolatile memory of the memory 16, the command sequence is registered in the mobile phone 5, and the radio wave off mode setting becomes valid.

  FIG. 8 shows an example of data stored in the memory 16. As a result of the writing unit 14 executing the command sequence extracted from the MMC by the parser unit 13, the specified memory area of the memory 16 The value indicated by the command string is written. There are three memory areas: phone: radio # offmode.date, phone: radio # offmode.start, phone: radio # offmode.end, each of radio off mode setting date, radio off mode start time, radio off mode end time Is stored. In the example of this figure, “June 20, 2003” is written on the radio wave off mode setting date, “8 o'clock” at the radio off mode start time, and “9 o'clock” at the radio off mode end time.

The clock unit 17 measures the current date and time, and passes the information to the control unit 11.
The mode transition unit 18 monitors the current date and time counted by the clock unit 17, and when it matches the date and time information related to the radio wave off mode setting stored in the memory 16, the mode transition unit 18 changes the cellular phone 5 from the normal mode to the radio wave off mode. Or the transition from the radio wave off mode to the normal mode is controlled. The mode transition unit 18 changes the mode flag according to the mode state, and the on / off state of the switch 9 is controlled by the mode flag.

The mode flag is a flag indicating a mode state in the mobile phone 5, changes in response to a signal from the mode transition unit 18, and is written in the memory 16. “0” is indicated in the normal mode, and “1” is indicated in the radio wave off mode.
The operation unit 19 has keys arranged so that input of telephone numbers, characters, and the like and various operations can be performed. By these key operations, the browser 12 is activated and a web page is browsed via the network. It becomes possible.

Here, in the mobile communication device according to the present invention, after the radio wave off mode setting command is downloaded from the web page, the radio wave off mode is actually set on the mobile phone 5 and then the radio wave off mode ends and the normal mode is set. The flow until returning will be described with reference to FIG.
First, the browser 12 of the mobile phone 5 is activated, and the departure date and arrival date and time of the train are viewed from the railway company web page as shown in FIG. 5 (step S1). When browsing the information, the MMC in which the command string is described in the XML format is downloaded to the browser 12 via the network 3 (step S2). The parser unit 13 in the browser 12 detects the tags <mmc mmcID ...> and </ mmc> from the MMC (step S3), and extracts the command string described in the tag <method ... /> (Step S4). Next, it is verified whether or not the command string extracted by the parser unit 13 can be executed by the mobile phone 5 (step S5). If it is determined that the command sequence has a problem for some reason and is invalid, "OK" is clicked on the screen displaying the departure date and arrival date and time as shown in FIG. At the same time, a message indicating that the radio wave off mode setting registration is not performed is displayed together with an error display (step S6). If it is determined that the command string is executable, on the screen prompting the user to select whether or not to set the radio wave off mode as shown in FIG. 6 (step S7), if “Yes” is selected, The radio wave off mode setting date, radio wave off mode start time, and radio wave off mode end time are written in the memory 16 (step S8). This completes the registration of the radio wave off mode setting. Here, if the writing to the memory 16 is not performed normally due to a problem with the command string (step S9), a message indicating that the radio wave off mode setting registration cannot be performed together with an error display. Is displayed (step S10).

Even when “No” is selected in step S7, the memory 16 is not written and the radio wave off mode setting registration is not performed.
The mode transition unit 18 monitors the date and time counted by the clock unit 17, and when it matches the start date and time of the radio wave off mode stored in the memory 16 (step S11), the mode flag is changed from “0” to “1”. To "". In response to the change of the mode flag, the switch 9 is turned off to stop the power supply to the function of transmitting / receiving the telephone of the transmission / reception unit 7 and the function of transmission / reception of mail and web, so that the cellular phone 5 is in the radio wave off mode. (Step S12).

  Next, when the clock unit 17 indicates the end date and time of the radio wave off mode stored in the memory 16 (step S13), the mode transition unit 18 changes the mode flag from “1” to “0”. In response to this change, the switch 9 is turned on, and the cellular phone 5 is returned to the normal mode by resuming the power supply to the transmission / reception function of the transmission / reception unit 7 and the transmission / reception function of mail and web. (Step S14).

  As described above, when a ticket is reserved, the user simply browses the date and time information on departure and arrival posted on the web page managed by the railway company using a mobile phone, Can be set. Then, the start and end of the radio wave off mode are automatically controlled. In this way, by setting the radio wave off mode on the railway company side, it is possible to reduce forgetting to set the radio wave off mode by the user, and to contribute to the realization of a comfortable in-vehicle environment.
