If the software or configuration parameters of the second user terminal 4 are changed (YES), B2 executes the process in step S202. Second user terminal 4 in accordance with the change in the contract plan. If the software or configuration parameters have not been changed (NO), Server 2 will not process Ending.

[0063] (Step S202) The plan change section 206 of server 2 changes the contract plan. Specifically, the plan change section 206 changes the current contract plan stored in memory device 200B. Also, The device control unit 203 stores the contract plan change history in the storage device 200B.

[0064] (Step S203) The billing amount change unit 207 of Server 2 displays the billing amount for the contract plan before the change and the contract plan after the change. (For example, compare the monthly charges) and see if the charges for the new contract plan are the same as those for the previous contract plan. Determine if the new contract plan's fee is higher than the previous contract plan's fee. If the amount is higher (YES), Server 2 executes the process in step S204. If the fee for the later contract plan is not higher than the fee for the previous contract plan (NO), - Ver 2 executes the process in step S205.

[0065] (Step S204) The billing amount change unit 207 of server 2 changes the billing amount for a predetermined period (for example, one month) including the time of change. The amount will be changed to the billing amount for the revised contract plan.

[0066] (Step S205) The billing amount change unit 207 of server 2 calculates the billing amount for a predetermined period including the time of change, based on the contract amount before the change. The charge amount will remain the same as the previous contract plan, and the charge will revert to the previous contract plan at the start of the next specified period or thereafter. Change to an amount.

[0067] (Emergency change processing) Figure 11 is a flowchart showing an example of emergency change processing in Information Processing System 1. The following describes an example of emergency change processing for Information Processing System 1, with reference to Figure 11. .

[0068] (Step S301) The determination unit 204 of server 2 receives, for example, emergency alerts from the Japan Meteorological Agency or local governments from the receiving unit 20 Determine whether server 1 has received it or not. If an emergency alert or similar is received (YES), server 2 will: The process in step S302 is executed. If no emergency alerts have been received (NO), the service will be terminated. B2 terminates processing.

[0069] (Step S302) The determination unit 204 of server 2 determines that the current location of the second user terminal 4 is within the range of emergency alerts. Determine whether or not. If it is within the scope of the emergency alert (YES), Server 2 will step Execute the process for S303. If it is not within the scope of the emergency alert (NO), Server 2 will: Processing will now be terminated.

[0070] (Step S303) The transmission unit 202 of server 2 transmits software or configuration parameters to respond in an emergency. In this case, the software or setting parameters (second user terminal) that correspond to the GPS & Talk plan Software or settings that enable the use of the GPS sensor, microphone, and speaker mentioned in item 4. The fixed parameters are sent to the second user terminal 4, whose current location is within the emergency alert coverage area. In addition, an audio message was sent informing users that the GPS & Talk plan had been temporarily made available due to an emergency alert. Data and other information are transmitted to the second user terminal 4 and the corresponding first user terminal 3. That's good too.

[0071] (Step S304) The receiving unit 401 of the second user terminal 4 receives software or configuration packets transmitted from the server 2. Receive the meter.

[0072] (Step S305) The modification unit 405 of the second user terminal 4 changes the software stored in the storage device 200B or The receiving unit 401 changes the setting parameters to the software or setting parameters it receives and uses them. To enable use. In addition, the control unit 406 controls the software or that the modification unit 405 has made available. Depending on the configuration parameters, at least two or more hardware components of the second user terminal 4 Enable or disable one or more functions.

[0073] Furthermore, the determination unit 204 of server 2 uses software that supports GPS & Talk Plan or A predetermined period (e.g., one week or one month) has elapsed since the setting parameters were sent, or the system has become unresponsive. Determine if the emergency alert has been lifted, and if a predetermined period has elapsed or it is determined that the emergency alert has been lifted. If so, the transmission unit 202 will use software that corresponds to the GPS plan, which was the contract plan before the change. Share or setting parameters (software that enables the GPS sensor of the second user terminal 4) The setting parameters (A or configuration parameters) are sent to the second user terminal 4 to enable use, and the second user terminal 4 The configuration may be modified to support GPS plans.

[0074] Furthermore, in the explanation of Figure 11, the determination unit 204 of server 2 determines the current location of the second user terminal 4. It determines whether or not it is within the scope of the emergency alert, but the first user terminal 3 (for example, the first Location information is also obtained from the user terminal 3 (for example, by equipping it with a GPS sensor), and the determination unit 204 is when the current location of the first user terminal 3 or the second user terminal 4 is within the range of the emergency alert. It determines whether or not there is an emergency alert, and the current location of the first user terminal 3 or the second user terminal 4 corresponds to the emergency alert. If within the range, the transmission unit 202 of server 2 will send emergency response software or settings. Fixed parameters, in this case the software or setting parameters corresponding to GPS & Talk Plan (Enables the GPS sensor, microphone, and speaker of the second user terminal 4) (Software or setting parameters) The first user whose current location is within the range of the emergency alert The second user terminal 4, or the current location, associated with the identification number of terminal 3, is the target of the emergency alert. It may also be configured to send to a second user terminal 4 that is within range.

[0075] As described above, the second user terminal 4 has two or more pieces of hardware (for example, a microphone) (400F, speaker 400G, GPS sensor 400H, etc.) and software or settings A receiving unit 401 that receives parameters, and a storage unit that stores software or setting parameters.

[0080] The second user terminal 4 has two or more pieces of hardware (for example, microphone 400F, speaker) (e.g., GPS sensor 400G, GPS sensor 400H) and changes to software or setting parameters. A receiving unit 401 that receives instructions, and a memory that stores two or more software programs or setting parameters. Memory device 400B (storage unit) and software or setting parameters stored in memory device 400B Based on the meter, a control unit 406 controls at least one of two or more pieces of hardware. Based on the change instruction received by the receiving unit 401, two or more changes are stored in the storage device 400B. One or more software or configuration parameters It includes a modification unit 405 that changes the data to make it usable. And the control unit 406 changes Depending on the software or configuration parameters enabled by the unit, two or more hardware components Enable or disable at least one function. Thus, two or more software programs stored in the storage device 400B of the second user terminal 4 Alternatively, by switching the setting parameters to enable use, the second user terminal 4 can be added to the contract plan. It can be made compatible, making it highly convenient.

[0081] [Modification 2 of the First Embodiment] Furthermore, in the first embodiment and modified example 1 described above, the control unit 406 of the second user terminal 4 is, Depending on the software or setting parameters enabled by the modification unit 405, the second user terminal At least one of the two or more hardware features of the last 4 (either enabling or disabling) Instead of doing so, the configuration may restrict its use.

[0082] The second user terminal 4 has two or more pieces of hardware (for example, microphone 400F, speaker) (e.g., GPS sensor 400G, GPS sensor 400H) and receive software or setting parameters. A receiving unit 401 and a storage device 400B (which stores software or setting parameters) (100 million units) and based on the software or setting parameters stored in the storage device 400B, 2 A control unit 406 controls at least one of the above hardware components, and a storage device 400B is used to record The receiving unit 401 receives the software or setting parameters that have been stored.

And a control unit 406 Depending on the software or setting parameters made available by the modification unit 405, two or more Restrict the use of at least one hardware function. In this way, depending on the software or setting parameters that the modification unit 405 has made available By restricting the use of at least one function of two or more hardware components, the second user end... The ability to customize the end of the contract plan makes it highly convenient.

[0083] [Modification 3 of the First Embodiment] Furthermore, in the first embodiment and modified versions 1 and 2 described above, the modified part 405 of the second user terminal 4 The software is configured according to the usage history of two or more hardware components provided by the second user terminal 4. Alternatively, the configuration may involve changing the setting parameters. For example, it may support GPS & Talk Plan. When the specified software or configuration parameters are set, the second user terminal 4 Of the two or more hardware components it has, the GPS sensor 400H is frequently used, but Micro If the phone 400F and speaker 400G are hardly used, the modified part 405 is G Change the software or configuration parameters to be compatible with the PS plan. Furthermore, the modification unit 405 of the second user terminal 4 (automatically) changes the software or setting parameters. Instead of changing the data, the usage history of the two or more hardware devices provided by the second user terminal 4 is used. The system includes a recommendation section that accordingly recommends changes to the software or setting parameters to the first user. It may be considered complete. In this case, the first user's first user terminal 3 transmits according to the recommendation. When the receiving unit 401 receives a change instruction, the change unit 405 performs two or more hardware operations. The software or configuration parameters will be changed according to the usage history.

[0084] Furthermore, Server 2 will, in accordance with the usage history of two or more hardware devices provided by the second user terminal 4, The system includes an instruction unit that instructs the second user terminal 4 to change software or setting parameters. The modification unit 405 of the second user terminal 4 receives instructions transmitted from the server 2 via the receiving unit 401. This may result in a configuration that changes the software or setting parameters. Server 2 may also have this feature.

[0085] The modification unit 405 of the second user terminal 4 includes two or more pieces of hardware (for example, a microphone). Depending on the usage history of the 400F, speaker 400G, GPS sensor 400H, etc., the software Change the wear or setting parameters. In this way, the software or setting parameters are changed according to the usage history, for example If the second user terminal 4 has two or more pieces of hardware, the GPS sensor 400H is good If you use it, but rarely use the Microphone 400F or Speaker 400G. The modified part 405 was changed to software or setting parameters corresponding to the GPS plan. This makes it possible to do so, and is highly convenient.

[0086] Furthermore, as mentioned above, depending on the usage history of two or more pieces of hardware, the software or It may also be configured to include a recommendation section that suggests changing the setting parameters. In this case, the contract plan The first user can review or decide whether to change the settings, making it highly convenient.

[0087] [Second Embodiment] Furthermore, by changing the processing routine of the software running on the second user terminal 4, the contract The configuration may also be designed to accommodate changes in the plan. In this case, for example, Server 2 will have a contract plan In response to the change, the software sends an instruction to change the processing routine, and the second user terminal 4 receives When the signal unit 401 receives an instruction to change the processing routine, the change unit 405 receives the instruction from the receiving unit 401. Based on the confirmed change instructions, the software processing routine stored in memory device 400B The control unit 406 modifies the software processing routine that the modification unit 405 has modified. The second user terminal 4 can use at least one of the two or more hardware functions it has. It may be set to either "enabled" or "unavailable."

[0088] [Modification 1 of the second embodiment] Furthermore, in the second embodiment described above, the control unit 406 of the second user terminal 4 is the modification unit 405 Depending on the software processing routine that has been modified, the second user terminal 4 has two or more H Use of at least one function of the software (rather than enabling or disabling it) A configuration that restricts usage is also acceptable.

[0089] [Third Embodiment] Furthermore, in the first and second embodiments and their modified forms described above, the hardware provided by the second user terminal 4 Changes to the contract plan can be made to allow or disallow the use of the apparel, or to restrict its use. However, in server 2, depending on the change in the contract plan, the second user terminal 4 is equipped Restrict the transmission and reception of information about two or more pieces of hardware (e.g., location information or voice data). By doing so, it may be configured to accommodate changes in the contract plan. In this case, the contract on server 2 In response to changes in the plan (instructions to change software or configuration parameters), the second user terminal Of the two or more hardware components that the end 4 has, hardware other than the hardware that is designated as usable It includes a limiting unit that restricts the transmission and reception of information about protected or disabled hardware. You may do so.

[0090] [Fourth Embodiment] In the first embodiment described above, when the cost (charge amount) of the contract plan is paid in arrears, the charge amount is changed. An example of timing (see Figure 4) has been explained. In this fourth embodiment, the contract plan Please refer to Figure 12 for an example of the timing of changes to the charge amount when the fee (charge amount) is paid in advance. I will explain by referring to it. Figure 12 shows the timing of the charge amount change by the charge amount change unit 207 in the fourth embodiment. This is a diagram showing an example. Note that in the example shown in Figure 12, the predetermined period (for example, the period that constitutes the smallest unit of billing (1 week or The monthly GPS plan (shown as a black bar in Figure 12) costs 400 yen, and includes GPS & Talk. The fee for the plan (white belt in Figure 12) is assumed to be 500 yen. As shown in Figure 12, in the case of advance payment, the charge amount change unit 207 determines that the contract plan has been changed. If the change is made in the middle of the contract period, the charges for the original contract plan and the changed contract plan (for example) We compare the monthly charges and the charges for the changed contract plan, and the charges for the changed contract plan are less than the charges for the previous contract plan. If the cost is also high (for example, if the plan before the change was a GPS-only plan and the plan after the change was a GPS & Talk plan) , the amount of the shortfall between the time the contract plan is changed and the start of the next specified period (see example in Figure 12). Then, a charge of 100 yen will be applied. Furthermore, multiple contracts will be made between then and the start of the next designated period. Even if you change your run, the 100 yen charge will not be refunded, nor will you be charged again. . On the other hand, the billing amount change unit 207 changes the billing amount of the contract plan before the change to the billing amount of the contract plan after the change. If the price is higher than the original price (for example, if the original plan was GPS & Talk Plan and the new plan is GPS Plan) In this case, no charges will be incurred from the time the contract plan is changed until the start of the next specified period. In other words, in the fourth embodiment, if you pay the charge amount corresponding to the GPS & Talk plan in advance, Furthermore, there are no additional charges regardless of how many times you change your contract plan during the prepaid period. During the period, change your contract plan to the GPS & Talk plan and pay the remaining amount (in the example in Figure 12). If you pay 100 yen, you can change your contract plan any number of times during the specified period. No charges will be incurred. Note that the timing of the charge amount change shown in Figure 12 is just one example, and the actual timing may vary depending on the example shown in Figure 12. It's not limited.

[0091] Furthermore, each of the above embodiments and its modifications are all useful in carrying out the present invention. This merely illustrates one example of its concretization, and does not limit the technical scope of the present invention. It must not be interpreted in this way. That is, the gist of this invention, or its main features, It can be implemented in various forms without deviating from the above. For example, in the above, the contract plan While only GPS plans and GPS & Talk plans were available, the second user terminal 4 is equipped with Instead of using the GPS sensor 400H, the microphone 400F and speaker 400G are used. The user then subscribed to the "Talk Only Plan," which allows for the exchange of voice data with the first user terminal 3. It may also be added as a component. In addition, the hardware that the second user terminal 4 has may be added to the second user terminal 4. Hardware unavailable due to malfunction of part A or a problem with the software or configuration parameters. It is equipped with a detection unit that detects the state, and detects hardware failures, software or setting parameters If a hardware malfunction is detected and the service becomes unavailable, your contract plan will be switched. It may also be a configuration in which the GPS sensor 400H of the second user terminal 4 fails or The GPS sensor 400H is unavailable due to a software or configuration parameter malfunction. If the condition is detected, the contract plan will be switched to the "Talk Only Plan" and the second user terminal 4 Failure of at least one of the microphone 400F and speaker 400G or software Alternatively, the microphone 400F and speaker 400G may be usable due to a malfunction in the setting parameters. If a condition is detected that prevents this, the contract plan will be switched to the "GPS plan." This is a possible explanation. Furthermore, the microphone 400F and speaker 400 of the first user terminal 3 Microf issues due to failure of at least one of the G components or a malfunction of the software or configuration parameters. Even if it is detected that the Phone 400F and Speaker 400G are unavailable, the contracted plan You may also configure the system to switch to the "GPS plan". In addition, in each of the above embodiments, the software In response to instructions to change software or setting parameters, the second user terminal 4 has two or more hardware components. Hardware other than the hardware designated as usable or hardware designated as unusable among the wear This describes a form of restricting the sending and receiving of information about software, but also includes software and configuration parameters. Instead of issuing a data change instruction, the firmware (software) built into the hardware is used. It may also be possible to perform similar control in response to a change instruction.
