Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a disposable mobile communication terminal and a communication management system thereof, and more particularly, to a disposable mobile communication terminal which can be easily introduced into an existing mobile communication system and a communication management system thereof. A typical conventional mobile communication system is a mobile communication system such as a mobile phone, a mobile phone, and a PHS. It is also possible to perform data communication using a mobile phone or the like. In recent years, especially mobile phones and P
HS has spread rapidly because of its convenience and price. In the Great Hanshin Earthquake, the disaster resistance of mobile phones was proven unintentionally. On the other hand, service demands of users are becoming increasingly diversified, and there is a demand that mobile communication terminals are used only temporarily (one month, one week, etc.), only on weekends, or only at the time of disaster.

[0002]

2. Description of the Related Art In a conventional mobile communication system, a business operator manages subscriber information in a home memory station based on a contract with a subscriber (sale of mobile communication terminals), and also, every time a subscriber makes a call. In the meantime, the mobile switching center charges and updates the charge corresponding to the call time (call frequency), and collectively bills the subscriber for the basic charge and the total call charge every month.

[0003]

However, in the above-mentioned conventional method, since a long-term contract of the subscriber is premised, the procedure for joining and canceling the procedure must be complicated. In addition, subscribers must pay monthly.
Therefore, the user's request for temporary use cannot be effectively satisfied.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a disposable mobile communication terminal capable of effectively satisfying a user's request for temporary use, and a communication management system therefor. To provide.

[0005]

The above-mentioned problem is solved, for example, by referring to FIG.
The problem is solved by the configuration of (A). That is, the disposable mobile communication terminal of the present invention (1) refers to a home memory station that holds information relating to the usage limit of the disposable mobile communication terminal in a subscriber information storage area, and refers to the subscriber information of the home memory station. Exchange control of the mobile communication, and charging / updating the information on the usage limit of the disposable mobile communication terminal by subtracting it according to the communication time or the communication amount, and using the usage limit. In a disposable mobile communication terminal of a mobile communication system including a mobile switching center for monitoring over and a radio base station for performing a radio service of the mobile communication, a usage limit of the mobile switching center to its own terminal is exceeded. Notification means for notifying the user of the fact that the user has received the notification, and disconnecting the call request of the terminal after the notification by the notification means, or performing communication by calling the terminal. In which and a call control means for cutting the call.

In such a mobile communication system, a user gives a predetermined amount of money (equipment fee, basic fee, usage frequency /
Payment for the expiration date, etc.) and purchase a disposable mobile communication terminal. The user only has to purchase a terminal and the procedure is easy. The business operator registers information on the usage limit of the disposable mobile communication terminal (the number of uses / expiration date) in the subscriber information of the home memory station. The mobile switching center performs switching control of mobile communication with reference to the subscriber information of the home memory station, and also transmits information relating to the usage limit of the disposable mobile communication terminal by calling the terminal to the communication time or communication time. The charge / update is performed by a method of subtracting according to the amount, and the use limit is monitored. Then, the wireless base station provides a wireless service of the mobile communication.

In this type of mobile communication system, the user only needs to purchase a disposable mobile communication terminal when he or she wants to use it or in the event of a disaster, and there is no monthly payment. It can effectively satisfy the requirements of use. In addition, since the management of the usage limit of the disposable mobile communication terminal is performed by the network side, no special function and configuration are required for the disposable mobile communication terminal. Therefore, for example, an inexpensive version of an existing mobile communication terminal can be put on the market as a disposable mobile communication terminal, and the introduction is easy. However, the usage limit of the disposable mobile communication terminal is sometimes exceeded, so it is necessary to notify the user of this fact and operate the system smoothly.

In this regard, in the disposable mobile communication terminal according to the present invention (1), the notification means notifies the user of the fact that the notification has been received from the mobile switching center regarding the use limit over to the terminal itself, and The call control means disconnects the call request of the own terminal after the notification by the notification means, or disconnects the call in communication by the call of the own terminal. Therefore, the user can easily identify whether the communication (call) failure of the terminal is due to a failure of the terminal or the network (such as squelch termination) or the use limit is exceeded, and the smooth operation of the disposable mobile communication terminal is possible. (Determination of operation / non-operation) becomes possible.

The above-mentioned problem is solved, for example, by the structure shown in FIG. That is, the disposable mobile communication terminal according to the present invention (2) includes a home memory station that stores identification information of the disposable mobile communication terminal in a subscriber information storage area, and a mobile unit that refers to the subscriber information of the home memory station. In the disposable mobile communication terminal of the mobile communication system including a mobile switching center that performs communication switching control and a wireless base station that performs wireless service of the mobile communication, information on a use limit of the own terminal is held. Holding means, monitoring means for charging / updating information on the usage limit by calling the own terminal in accordance with the communication time or communication amount, and monitoring usage limit over, and the monitoring means Call control means for preventing a call from the own terminal by detecting the use limit over, or disconnecting a call in communication by the call from the own terminal.

[0010] In this type of mobile communication system, information relating to the usage limit is managed on the side of the disposable mobile communication terminal. Therefore, there is no need to add any further improvement to the existing home memory station or mobile switching center. On the other hand, in the disposable mobile communication terminal of the present invention (2), the holding means holds the information on the use limit of the own terminal, and the monitoring means stores the information on the use limit by calling the own terminal for the communication time. Alternatively, charging / updating is performed by a method of subtracting according to the communication amount, and monitoring for exceeding the usage limit is performed. Then, the call control means prevents the calling of the own terminal by detecting the use limit overrun of the monitoring means, or disconnects the call in communication by the calling of the own terminal.

Such a disposable mobile communication terminal can be easily realized by adding a simple program control function. Therefore, the user's request for temporary use can be effectively satisfied, and such a disposable mobile communication terminal can be easily introduced into an existing mobile communication system. Preferably, in the present invention (3), in the above present invention (2), the call control means does not accept an incoming call to the own terminal because the monitoring means detects that the usage limit of the own terminal has been exceeded.

Predetermined transmission frequency (number of transmissions, expiration date, etc.)
For a disposable mobile communication terminal that has exhausted the above, it is not preferable from the viewpoint of the purpose and operation of introducing the disposable mobile communication terminal to allow only the incoming call. Therefore, incoming calls to the own terminal are not accepted. The above problem is solved by, for example, the structure of FIG. That is, the disposable mobile communication terminal of the present invention (4) comprises a home memory station for holding identification information of the disposable mobile communication terminal in a subscriber information storage area, and a mobile unit with reference to the subscriber information of the home memory station. In the disposable mobile communication terminal of the mobile communication system including a mobile switching center that performs communication switching control and a radio base station that performs a radio service of the mobile communication, power is supplied to its own terminal by an operation of turning on power, In addition, a power switch unit having a control structure in which power cannot be turned off, a battery having a power capacity corresponding to a use limit of the terminal itself, and sealed in the terminal in a state where charging is not possible from the outside are provided.

[0013] In this case as well, the disposable mobile communication terminal manages its usage limit. However, the management is indirectly realized by the life of a battery having a power supply capacity corresponding to the use limit of the terminal. Such a disposable mobile communication terminal has a simple structure and can be provided at a low cost. In addition, for example, if the power is not turned on after the purchase, the user is prepared for future leisure or disaster. Also, once the power is turned on, the battery is discharged after a certain period of time, and there is no need to perform any management in the surroundings, and the battery cannot be used automatically.

The communication management system for a disposable mobile communication terminal according to the present invention (5) includes a home memory station capable of holding identification information of the disposable mobile communication terminal in a subscriber information storage area, and a subscriber of the home memory station. In a communication management system of the disposable mobile communication terminal of a mobile communication system including a mobile switching center that performs exchange control of mobile communication with reference to information and a radio base station that performs wireless service of the mobile communication, The home memory station has registration type information for discriminating a disposable mobile communication terminal from a normal mobile communication terminal in a storage area of the subscriber information, and the mobile switching center stores the registration type information of the home memory station. And the charging control is performed in a different manner for the disposable mobile communication terminal and the normal mobile communication terminal.

Therefore, with a simple configuration, it is possible to smoothly perform charging processing in a mobile communication system in which ordinary mobile communication terminals and disposable mobile communication terminals coexist. In addition, it is easy to introduce a disposable mobile communication terminal, and it is possible to set a flexible billing method based on various contracts for the disposable mobile communication terminal. Preferably, in the present invention (6), in the above-mentioned present invention (5), the mobile switching center assigns a charge for the call origination of a normal mobile communication terminal to the communication time or communication time of the mobile communication terminal. In the method of charging / updating by the method of adding according to the amount, and for the calling of the disposable mobile communication terminal of the present invention (1), information relating to the usage limit of the mobile communication terminal is added to the communication time or communication amount. In addition to charging / updating in accordance with a method of subtraction, the usage limit of the mobile communication terminal is monitored.

Such a mobile switching center can be easily realized only by adding the simple charging control program to the disposable mobile communication terminal. On the other hand, the disposable mobile communication terminal can use the same thing as a normal mobile communication terminal.
Also preferably, in the present invention (7), in the above present invention (6), the mobile switching center rejects a call request from a disposable mobile communication terminal whose usage limit has been exceeded, or Disconnect a call during communication that has exceeded the usage limit due to calling. Therefore, the usage limit of this type of disposable mobile communication terminal can be effectively managed.

Preferably, in the present invention (8), in the above-mentioned present invention (5), the mobile switching center assigns a usage fee for a call of a normal mobile communication terminal to the mobile communication terminal. Charging / updating is performed by a method of adding according to the communication time or communication amount, and no charging process is performed for the call of the disposable mobile communication terminal of the present invention (2) or (4).
According to the present invention (8), since the mobile switching center does not perform the charging process for the call of the disposable mobile communication terminal of the present invention (2) or (4), it is easy to control.

[0018]

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Note that the same reference numerals indicate the same or corresponding parts throughout the drawings. FIG. 2 is a diagram showing a configuration of the mobile communication system according to the embodiment, in which HLR is a home memory station having subscriber information and the like, STP is a common channel signal relay station, and MTS
1, MTS2 is a mobile switching center, MTS3 is a mobile switching center (gateway switch) connected to another operator's network (mobile network, etc.), MSC1 and MSC2 are mobile switching stations, BS1
To BS4 are radio base stations, MS1 to MS4 are mobile communication devices (mobile devices), solid lines are line-corresponding routes, and broken lines are line-non-corresponding signal routes.

Here, the MS1 is a conventional ordinary (mobile phone,
PHS etc.), and each time a call is made, the call is charged,
Monthly payment is required. The MS 2 is a disposable mobile device according to a first embodiment described later, and is an exchange-driven mobile device of a type used under the control of the usage limit by the exchange. The MS 3 is a disposable mobile device according to a second embodiment described later, and is a mobile device-driven disposable mobile device of a type in which the mobile device itself manages a use limit. The MS4 is a disposable mobile device according to a third embodiment described later, and is a mobile device-driven disposable mobile device of a type in which the mobile device itself manages a usage limit based on the life of a battery.

One example of the mobile switching system is capable of processing the above-mentioned ordinary mobile device and any type of disposable mobile device,
Each of the mobile stations MS1 to MS3 can receive the respective communication service regardless of the wireless zone. It should be noted that the mobile communication system may be configured to service only one type of disposable mobile device.

FIG. 3 is a diagram for explaining the contents stored in the home memory station according to the embodiment. The HLR subscriber information includes registration (contract) information for each subscriber. The storage format of certain subscriber information is shown in the right column. The “registration type” is information for the mobile switching system to distinguish between a conventional (normal) mobile device and a disposable mobile device, and is newly provided. Registration type =
“0” is a normal (conventional) mobile device, registration type = “1” is an exchange-driven disposable mobile device, registration type = “2” is a mobile device-driven disposable mobile device, and registration type = “3” is battery management. Each represents a disposable mobile device.

Information such as "secret type" to "secret key"
Similar to the conventional system, the mobile switching center uses these pieces of information in common for a normal mobile station and a disposable mobile station. The information of “usage frequency” to “used call time” is based on the fact that the mobile exchange is an exchange-driven disposable mobile device (registration type =
It is information for managing the usage frequency and the like in 1), and is newly provided. "Use frequency" is the call frequency or remaining call frequency by calling the disposable mobile device, "Use call frequency" is the call frequency or remaining call frequency of the disposable mobile device, and "Total use time" is the disposable mobile device (For example, year x month day x year x month x month x day), and "use talk time" indicates the total talk time or the remaining total talk time by calling the disposable mobile device.

Which of the "frequency of use" to "use of talk time" is managed is based on a contract with the subscriber. in this case,
For example, by adding the sub-types 1 to 4 to the registration type = 1, the management method such as “frequency of use” = 11, “number of times of use of call” = 12, “total time of use” = 13, and “use time of use” = 14 May be distinguished. Alternatively, when the registration type is set to 1 and the subscriber selects the management of the "use frequency" (purchases a mobile device of the use frequency management), the "use frequency" = 100
The management method may be distinguished by recording "0 or Null" in the other "number of used calls" to "used call time". Needless to say, the subscriber can select any combination of "the number of uses" to "the talk time". In this case, if any of the selected conditions (for example, the remaining use frequency = 0) is satisfied, the mobile device cannot be used even if other conditions (for example, the number of use calls = 0) are not satisfied. Alternatively, if one of the selected conditions (for example, the remaining use frequency = 0) is satisfied but the other conditions (for example, the number of used calls = 0) are not satisfied, the mobile device can be further used. It is up to the operator to decide what kind of service to provide.

A memory (MEM) composed of an OM or the like, 6 is a common bus of the CPU 51, 7 is a battery (BT), 8 is a power switch unit (SW), and 9 is a battery charging contact terminal.

Although the mobile station MS2 is originally disposable, the use limit of the mobile station MS2 is managed by the mobile switching center. (Telephone, PHS, etc.) There is hardly any difference from the MS1, and the configuration can be substantially the same. Therefore, it is not an exaggeration to say that whether or not the mobile device MS2 is disposable is basically simply based on the contract with the business operator (contents of the HLR registration type).

The user purchases the disposable mobile station MS2 at, for example, a convenience store. The purchase price includes a call fee for 500 times in advance, and the user does not need to perform a complicated subscription procedure as in the related art. On the other hand, as for this mobile station MS2, since the subscriber registration of the "disposable mobile station" has been performed in advance on the network side, the disposable mobile station MS2 can talk only if the power is turned on from the point of purchase. Thereafter, the usage limit is managed by the mobile exchange.

FIG. 5 is a flowchart of the exchange processing for the disposable mobile station MS2 according to the first embodiment. M
The call request of S2 reaches MSC1 via BS2. MS
C1 makes an inquiry to the HLR based on the outgoing call (SET UP) information in the same manner as in the prior art, and obtains the necessary subscriber information for the subscriber. In step S1, it is determined based on the registration type of the subscriber information whether or not the mobile device is a disposable mobile device (in this example, a switch-driven frequency management type disposable mobile device). If the mobile device is not a disposable mobile device, the process proceeds to step S2, and a normal call reception process is performed. In the case of a disposable mobile device, it is further determined in step S3 whether or not the remaining use frequency = 0.

If the remaining number of uses = 0, a call rejection response is returned to MS2. Upon receiving this, the MS2 proceeds to step S4
Executes a predetermined call rejection process for the user. This processing is, for example, output to a speaker such as a busy tone, an alarm sound, or a voice message "no remaining frequency" provided in MS2, or a display on a display unit such as a text message "Dosunashi Hasshinfuka" provided in MS2.
Alternatively, the power of the MS 2 is automatically turned off. Thereby, the user can know that the MS 2 cannot make a call due to the interruption.

If it is determined in step S3 that the remaining number of uses is ≠ 0, a call acceptance response is returned to the MS 2. In the following step S5, a transmission process similar to the conventional one is performed, and eventually M
When S2 returns the connection response CNN AC, the communication state is established.
In step S6, the MSC 1 receiving the request disposes the disposable mobile device (in this example, the exchange-driven frequency management type disposable mobile device).
It is determined whether or not. If the mobile device is not a disposable mobile device, a normal charging process is performed in step S7. In the case of a disposable mobile device, a charging process from step S8 is performed.

In step S8, the remaining usage frequency -1 (10
Yen). In Step S9, for one time (10 yen)
Start timer for In step S10, it is determined whether or not it is a disconnection request DISC from the MS 2, and if it is not a disconnection request DISC, it is further determined in step S11 whether or not a timeout has occurred. If there is no timeout, the process returns to step S10.
In the case of a timeout, it is determined in step S12 whether or not the remaining use frequency = 0. If the remaining usage frequency ≠ 0, the process returns to step S8, and the remaining usage frequency -1 is performed again. If the remaining number of uses = 0, the MS 2 is notified that the contract has expired.

In response to this, the MS 2 performs a predetermined notification process in step S14. Thereby, MS2 notifies the user that the call will be disconnected after a while,
Like the beep sound at 10 yen remaining on a public telephone,
Generates a predetermined alarm sound or the like. Step S1
If it is determined that the call is disconnected from the MS 2 (corresponding to an ON hook operation), the timer is stopped in step S13. In the following step S15, a call disconnection process similar to the conventional one is performed. At this time, although not shown, the contents of the updated remaining use frequency are recorded in the subscriber information of the HLR.

In the above, the case of management based on the "number of uses" has been described, but the present invention is not limited to this. In the case of the used number of calls (remaining number of calls), the MSC 1 decrements the remaining number of calls by one for each outgoing call (may include incoming calls). I do. In the case of the total use time (absolute expiration date), the contract expiration date of the MS 2 is monitored by the absolute time, and when the expiration date is exceeded, the use is disabled. In the case of used talk time (remaining talk time), MS
For example, the total talk time of No. 2 is monitored in units of one minute, and if it exceeds the contract time, it becomes unavailable. MS2 in this case
If you do not talk once after purchasing, this MS2 will stay alive forever.

The telephone number whose contract has expired can be re-assigned to another disposable mobile station, and thus a finite number of telephone numbers can be reused. In the above description, the call restriction at the time of calling by the MS 2 has been described. For the MS 2 whose usage limit has been exceeded, the network side (mobile exchange) is configured not to accept the call addressed to the MS 2. You may.

FIG. 6 is a diagram showing a configuration of a disposable mobile device MS3 according to the second embodiment (mobile device-driven frequency management type). The MS 3 is a disposable mobile device that manages the usage limit by itself, and the memory 52 of the MS 3 stores the control program of FIG. 7 executed by the CPU 51, the mobile station number, the remaining use frequency, the timer value per frequency, and the like. Data is stored. Other configurations may be the same as those in FIG.

FIG. 7 is a flowchart of the exchange processing for the disposable mobile station according to the second embodiment. When the user performs an outgoing call operation in MS3, it is determined in step S21 whether or not the remaining use frequency = 0. Remaining frequency =
If it is 0, a predetermined call rejection process is executed in step S22. This call rejection process outputs a busy tone, an alarm sound, or a voice message "No remaining frequency" provided in MS3 to speaker S, or displays a text message "Dosunashi Hasshinfuka" provided in MS3 on display DISP, Alternatively, the CPU 51 automatically turns off the power of the MS 3.

When the remaining number of uses is ≠ 0, a call is made in the same manner as a normal mobile station, and the call is made via the BS3 to the MSC2.
Leads to. Based on the received call-up (SET UP) information, the MSC 2 queries the HLR in the same manner as in the related art to obtain necessary subscriber information. In the following step S23, each device performs a transmission process similar to the conventional one, and the MS 3 eventually connects to the connection response CNN ACK.
Is returned, the call is in progress.

In response to this, the MSC 2 proceeds to step S3
In step 1, it is determined whether or not the mobile device is a disposable mobile device (mobile device-driven frequency management type disposable mobile device). If the mobile device is not a disposable mobile device, a normal billing process is performed in step S32. In the case of a disposable mobile device, no billing process is performed. Meanwhile, MS
In step S3, the remaining usage frequency -1 is performed in step S24. In step S25, a timer for one time is started. In step S26, it is determined whether or not there is a call disconnection (ON hook) operation from the user. If not, it is further determined in step S27 whether a timeout has occurred. If there is no timeout, the process returns to step S26. In the case of a timeout, the number of remaining uses =
It is determined whether it is 0 or not. If the remaining usage frequency ≠ 0, the process returns to step S24, and the remaining usage frequency -1 is performed again. Thus, the call is continued.

If the remaining number of uses = 0, step S
At 29, a predetermined notification process is performed to the user. For example, a predetermined alarm sound is generated like a beep sound for the remaining 10 yen in a public telephone. Then, when a predetermined time has elapsed, a call disconnection request DISC is transmitted to the MSC 2. If it is determined in step S26 that the user has issued a call disconnection request, M
A call disconnection request DISC is transmitted to SC2, and step S
At 30, the timer is stopped. In step S33, a call disconnection process similar to the conventional one is performed. It goes without saying that corresponding processing is performed in the case of “used call count” to “used call time”.

Although the above has been a description of the call restriction at the time of making a call by the MS 3, the MS 3 whose usage limit has been exceeded may be configured not to accept incoming calls addressed to the MS 3. FIG. 8 is a diagram showing a configuration of a disposable mobile device MS4 according to the third embodiment (mobile device-driven battery management type).

The MS 4 is also a disposable mobile device that manages the usage limit by itself, and the memory 52 of the MS 4 has a CPU 51.
9 and the data such as the mobile station number. However, the management of the usage limit is performed based on the life of the battery 7. For this purpose, the battery 7 is MS4
The battery is sealed inside, and the battery cannot be replaced or charged from the outside. On the other hand, the power switch unit 8 can only be turned on mechanically and electrically. Once the power is turned on by the power key PW, the power cannot be turned off thereafter. Furthermore, this battery 7 is MS
4 has a power capacity according to the use (contract) period,
When the usage period is, for example, three months, a power supply capacity enough to withstand three months of use when the MS 4 is used at a normal frequency is provided. In the case of continuous communication using the MS 4, the communication power may be larger than the standby power, and may not be used before three months.

As described above, after the expiration of the contract (use) period, the MS 4 cannot be used because the battery 7 is exhausted.
Therefore, on the mobile switching center side, basically, there is no need to perform any period management for the MS4. Therefore, such an MS 4 can be easily introduced without any other change to the existing mobile switching system. However, the contract expiration date (when a separate expiration date is provided) may be exceeded during the call of the MS 4, or the battery may be replaced maliciously and the use expiration date may be substantially extended. Therefore, the mobile switching center according to this embodiment performs time limit management in a confirming sense.

FIG. 9 is a flowchart of a switching process for a disposable mobile device according to the third embodiment. The outgoing call of MS4 reaches MSC2 via BS4. The MSC 2 queries the HLR based on the calling (SET UP) information in the same manner as in the related art to obtain necessary subscriber information. In step S41, it is determined whether or not the mobile device is a disposable mobile device (mobile device-driven battery management type disposable mobile device MS4) based on the registration type of the subscriber information. If it is not a disposable mobile device, step S42
To perform normal call acceptance processing. In the case of a disposable mobile device, it is further determined in step S43 whether the contract has expired. For example, a separate contract expiration date (○ year ○ month ○ day ~ × year ×
If “month × day” is provided, this determination is made by comparing the current time information with the contract term (× year × month × day) of the subscriber information.

If the contract has expired (× year × month × day has passed), a call rejection response is returned to the MS 4. M who received this
S4 is a step S44 for notifying the user of the fact.
Performs a predetermined call rejection process. This call rejection processing is performed, for example, by outputting to the speaker S such as a busy tone, an alarm sound, or a voice message "No remaining number" provided in the MS4, or to a display unit 41 such as a text message "Dosunashi Hasshinfuka" provided in the MS4. Is displayed.

If it is determined in step S43 that the contract has not expired, a call acceptance response is returned to the MS 4.
In the subsequent step S45, each device performs a transmission process similar to the conventional one. When the MS 4 outputs the connection response CNN ACK, the communication state is established. In step S46, the MSC 1 that has received this determines whether or not the mobile device is a disposable mobile device (mobile device-driven battery management type disposable mobile device MS4). If the mobile device is not a disposable mobile device, a normal charging process is performed in step S47. In the case of a disposable mobile device, M is set in step S48.
It is determined whether or not it is the call disconnection request DISC from S4, and the call disconnection request is made.
If it is not a disc, it is further determined in step S49 whether the contract has expired. If the contract has not expired, step S4
Return to 8. If the contract has expired, the MS 4 is notified that the contract has expired.

In response to this, the MS 4 proceeds to step S50.
Then, for example, a predetermined alarm sound such as a beep sound when the remaining 10 yen is paid by a public telephone is generated. Step S4
In the case of the call disconnection request from the MS 4 in the discrimination of step 8, the step S
Go to 51. In step S51, a call disconnection process similar to the conventional one is performed. In the above embodiment, an example of application to a disposable mobile phone has been mainly described, but the present invention is not limited to this. Obviously, the present invention can be applied to various disposable mobile communication terminals that realize multimedia communication such as data communication and image communication.

Although a plurality of preferred embodiments of the present invention have been described, it goes without saying that various changes in the configuration, control, and combinations thereof can be made without departing from the spirit of the present invention. There is no.
