Description

  The present invention relates to a mobile phone terminal using radio communication, and more particularly to a mobile phone terminal capable of making a call.

When communication is performed using a mobile communication terminal such as a mobile phone terminal or a PHS terminal, for example, in the case of a mobile phone terminal, by connecting the mobile phone terminal and a wireless base station by a predetermined wireless communication method, A communication service that enables a call with a mobile phone terminal or a general telephone is provided.
In addition, examples of the communication service of the mobile phone terminal include an e-mail transmission / reception service by packet communication and a web browsing service. By always carrying this mobile phone terminal, it is possible to receive a communication service at any time within the reach of communication radio waves.
Furthermore, the mobile phone terminal is provided with various functions such as a function of recording various personal information such as a telephone number and an address in a memory, and various settings can be made for the operation mode of the terminal. . Due to such convenience, the penetration rate of mobile phone terminals is steadily increasing.

The mobile phone terminal as described above has an advantage that the user can always carry it, but there are places and situations that are inappropriate for using the mobile phone terminal. However, at present, whether or not to use a mobile phone terminal depends on the manners of the user.
In addition, of course, when using a mobile phone terminal, a beep that is generated without regard to the user's intention, such as in a movie theater or library where a quiet environment is required or during a meeting. But it will be annoying to others. Therefore, the mobile phone terminal is set with a normal mode that notifies the incoming call by sounding and a manner mode that notifies the incoming call without sounding, so that the user can change the mode as needed. It is common.
In mobile phone terminals in which the user changes the incoming mode in this way, settings are often not changed appropriately. For example, when the user leaves the seat if the manner mode remains set There is a risk that you may miss an incoming call, etc., and conversely if you set it to non-manner mode, the ringtone will ring around you and may cause trouble for other people depending on the location. It was.

Regarding the technology for automatically setting the incoming mode in such a mobile phone terminal, the following incoming call restriction control method for a mobile phone has been proposed.
This is because the mobile phone having short-range wireless communication means separately from the wireless communication means for performing wireless communication with the mobile phone base station, and the incoming call restriction device having wireless communication means equivalent to the short-range wireless communication means of the mobile phone. The mobile phone and the incoming call restricting device communicate with each other by the short-range wireless communication means in a state where the mobile phone is in the vicinity of the incoming call restricting device, thereby performing the incoming call restricting control of the mobile phone required in a specific area. (For example, refer to Patent Document 1).

Japanese Patent Application Laid-Open No. 2001-285952

However, in the incoming call restriction control method described in Patent Document 1, the incoming call restriction is limited to a specific area.
In addition, an incoming call restricting device installed in such a specific area is initially operated in the search mode, and is activated in order to send a search mode operation command to the short-range wireless communication control unit of the mobile phone terminal. It was difficult to construct a compact system as a whole because a power supply was required, and the system could not be easily constructed. In addition, when performing system maintenance, it is necessary to go to the place where the incoming call restricting device is installed, which may take time and effort, and there remains a problem in terms of cost.
Furthermore, in the above prior art, for example, if a mobile phone is misplaced or lost, a third party may obtain it and use it without permission. I can't do that either.
An object of the present invention is to provide a mobile phone terminal capable of solving the conventional problems.

  In the first aspect of the present invention, the wireless communication means for performing wireless communication with the base station, the IC tag detection radio wave is periodically transmitted, and the identification signal transmitted from the IC tag existing in the predetermined area is transmitted. An IC tag monitoring means for detecting and an operation mode setting changing means for changing the operation mode to a predetermined mode based on the presence / absence of the identification signal are provided.

  According to a second aspect of the present invention, in the cellular phone terminal according to the first aspect, the operation mode is set to the incoming mode, and the predetermined mode is a normal mode for notifying an incoming call by sounding and a manner to notify the incoming call without sounding One of the modes is a feature.

  According to a third aspect of the present invention, in the mobile phone terminal according to the first aspect, the operation mode is a transmission mode, and the predetermined mode is one of a transmission possible mode and a transmission disabled mode. And

  According to a fourth aspect of the present invention, in the mobile phone terminal according to any one of the first to third aspects, an antenna unit for transmitting and receiving radio waves of the IC tag monitoring unit and the wireless communication unit is provided in common. It is characterized by.

  According to the mobile phone terminal of the present invention, the operation mode setting change is not automatically changed by the terminal user, but automatically changed based on a response from an IC tag present in the vicinity of the mobile phone terminal to change the usage state. Since it can be set to an appropriate setting, it is possible to maintain an operation mode suitable for the surrounding environment where the mobile phone terminal is placed, without forgetting to change. In addition, since the system for setting the operation mode is composed of each mobile phone terminal and an IC tag for transmitting identification information unique to the mobile phone terminal, the entire system is compact. A large-scale construction that is installed every time is unnecessary, and maintenance can be performed for each mobile phone terminal, which is advantageous in terms of cost.

The cellular phone terminal according to the present embodiment includes a wireless communication means for performing wireless communication with a base station, an IC tag detection radio wave periodically transmitted, and an identification signal transmitted from an IC tag existing in a predetermined area IC tag monitoring means for detecting the operation mode, and operation mode setting change means for changing the operation mode to a predetermined mode based on the presence or absence of the identification signal.
Therefore, it is possible to determine that the predetermined IC tag is within the communicable range of the mobile phone terminal based on the presence / absence of the identification signal acquired from the IC tag, and the operation according to the usage mode and usage status of the mobile phone terminal The mode can be set appropriately.

The IC tag may be attached to clothes, accessories, or carry-on items worn by the terminal owner.
That is, as described above, the clothes or the like with the IC tag attached and the mobile phone terminal are held in a closely linked state within a predetermined area, and the mobile phone is determined depending on whether the user is in the vicinity of the terminal or not. The operation mode setting of the terminal can be automatically changed.

In addition, the operation mode may be an incoming mode, and the predetermined mode may be either a normal mode that notifies an incoming call by sound generation or a manner mode that notifies an incoming call without sounding.
That is, the distance between the mobile phone terminal and the user wearing the IC tag is determined, and when the IC tag is within a communicable range from the mobile phone terminal, the manner mode is set, for example, and the response signal from the IC tag is If it is not detected, the incoming call setting change processing such as setting to the non-manner mode can be performed.
So, for example, if you normally wear a mobile phone and have a manner mode that notifies you of incoming calls without sounding with a vibrator or light emission, if there is no identification signal, the normal mode that notifies you of incoming calls with sounding If it is set to automatically switch to, even if the cellular phone is left in the room by chance, the incoming call can be recognized by the ring tone, so it can be dealt with immediately.

In addition, the operation mode may be a transmission mode, and the predetermined mode may be either a transmission enable mode or a transmission disable mode.
For example, if there is no identification signal and the operation mode is set to the transmission disabled mode in advance, if the cellular phone is misplaced or lost, the cellular phone does not exist near the user and is identified No signal is generated, and the mode is automatically switched to the transmission disabled mode, so that unauthorized use by a third party who has picked up the mobile phone can be prevented in advance.

By the way, the above-described mobile phone terminal can be provided in common with an antenna unit for transmitting and receiving radio waves of the IC tag monitoring unit and the wireless communication unit.
As a result, the mobile phone terminal can be configured in a compact manner, and by adding the antenna unit, the design is not impaired, and the mobile phone terminal having an incoming call setting change processing function and having excellent convenience is provided. Can be provided.

  In the mobile phone terminal of the present embodiment, the communicable distance between the IC tag and the IC tag monitoring means is set in a range of 1 to 2 m, and the IC tag and the mobile phone terminal are within a predetermined area. It can be kept in a closely related state. This communicable distance can be adjusted by selecting a frequency band to be applied. Note that if the communicable distance is less than 1 m, the IC tag and the mobile phone terminal are too close to each other, which is not preferable because the frequency of switching the incoming call setting may increase and malfunction may occur. If the distance exceeds 2 m, it is necessary to increase the frequency used for communication, and this tends to increase the cost, which is not preferable.

The wireless communication means includes a transmission unit and a reception unit for performing wireless communication between the mobile phone base station and the antenna unit, a control unit for controlling them, a power supply unit for supplying power, and the like. Yes.
In general, in a mobile phone terminal, the wireless communication means is first connected to a mobile communication exchange, and in the case of communication between a general phone and a mobile phone, the mobile phone switch and the fixed phone switch are connected to each other. Communication is now possible. The mobile phone terminal always communicates with the base station via radio waves, registers its location in the memory for location registration, and when the mobile phone number is dialed, it connects to the exchange in the registered area, and A calling signal is transmitted from the station. The location registration area is a collection of zones of several base stations. When a mobile phone moves to another area and receives radio waves from that base station, it re-registers the location and switches to the area switch. It comes to be connected. When the mobile phone terminal moves beyond the zone of a base station to the next zone, the exchange switches to the base station with the stronger radio wave so that the call is not interrupted, enabling communication by the mobile phone terminal. Yes.
An operation key, a call button, a cut button, and an LCD are provided on the surface of the casing of the mobile phone terminal having such wireless communication means, and a receiver is provided on the upper part of the LCD and a microphone is provided on the lower part thereof. An antenna portion is provided on the upper portion of the housing so as to be extendable and retractable so that the antenna is pulled out when making a call. A power supply unit such as a charging pack is provided at the rear of the housing. Each of these components is connected to a control unit housed in the housing.

  The IC tag monitoring means has a function of periodically transmitting an IC tag detection radio wave and detecting an identification signal transmitted from the surrounding IC tag, and is connected to a control unit of the mobile phone terminal. ing. The IC tag is composed of an IC chip and a coiled antenna unit connected to the IC chip, and the IC chip is divided into a storage unit, a power supply rectification unit, a transmission unit, a reception unit, etc. Have When the IC tag receives radio waves from the mobile phone terminal, an induced voltage is generated in the receiving coil in the IC tag, and radio waves are transmitted from the transmitting coil in the IC tag by this power. Thus, the mobile phone terminal can receive the transmission radio wave from the IC tag. Information such as an ID code for identifying the user of the mobile phone terminal can be recorded in the storage unit of such an IC chip. In addition to the battery built-in type, the IC tag uses non-contact power transmission technology that uses the principle of electromagnetic induction by receiving radio waves from the IC tag monitoring means of the mobile phone terminal without using a battery and using the antenna part of the IC tag. What is activated can be applied. IC tags have radio readable distances ranging from several millimeters to about 2 meters corresponding to their operating frequencies (for example, 400 to 530 KHz, 135 KHz to 13 MHz, 2.45 GHz, etc.), and are used according to their applications. The Such an IC tag is capable of individual recognition by non-contact and direction-independent information reading, and has excellent durability (vibration, dirt, wear, etc.).

The function of the operation mode setting changing means is realized by a circuit unit having a function of changing the operation mode with the mobile phone base station based on the presence / absence of an identification signal from the IC tag. By this operation mode setting changing means, the clothes or belongings of the user with the IC tag attached are close to the mobile phone terminal at a distance where the signal from the IC tag reaches the mobile phone, and the signal from the IC tag is sent to the mobile phone. It is determined that the IC tag is away from the mobile phone at a distance that does not reach the terminal. Based on this determination result, the operation mode of the mobile phone terminal can be switched to a predesignated mode.
When the operation mode setting changing means functions as the incoming call setting changing means, the incoming call setting is switched from the manner mode to the non-manner mode based on the presence / absence of the identification signal from the IC tag, and the appropriate setting state is always obtained. As a result, it is possible to selectively use according to the usage environment of the mobile phone terminal, and it is possible to maintain good usability.

Hereinafter, a mobile phone terminal according to an embodiment of the present invention will be described more specifically based on the drawings. In the present embodiment, the operation mode setting change unit functions as the incoming call setting change unit.
FIG. 1 is a schematic block diagram of a mobile phone terminal according to the present embodiment. As shown in the figure, the mobile phone terminal 10 according to the present embodiment includes a transmitter 12 such as a speaker and a receiver for performing wireless communication with the mobile phone base station via the antenna unit 11 as its wireless communication means. A receiving unit 13, a control unit 14 for controlling the transmitting unit 12, the receiving unit 13, and the like, and a power supply unit 15 for supplying power to them are provided. The control unit 14 is connected to a tag reader (IC tag monitoring means) 17 for periodically transmitting an IC tag detection radio wave via the antenna unit 16 and detecting an identification signal transmitted from the surrounding IC tag 20. ing. The control unit 14 includes a control circuit including a CPU and a memory. The tag reader 17 is controlled via an incoming call setting change program stored in the memory of the control unit 14 so that the incoming call setting with the mobile phone base station is appropriate. It has been changed to.

  The IC tag 20 is mounted on a tag mounting body S (see FIG. 3) such as clothes and carry-on items of the user of the mobile phone terminal 10, and holds identification information for identifying the user. The IC tag 20 has a size of several millimeters to several centimeters excellent in environmental resistance, and has a function capable of communicating with the tag reader 17 by radio waves or electromagnetic waves. The antenna portion 21 formed in a coil shape and the IC chip 22. The IC tag 20 has various shapes such as a label type, a card type, a coin type, and a stick type, and the communication distance ranges from several millimeters to several meters depending on the frequency band to be applied. Can be used properly according to the environment. Currently, frequencies of 135 KHz, 13.56 MHz, and 2.45 GHz are mainly used, and the communication distance is 1 m to 2 m. However, it is known that the 800/900 MHz UHF band can be used.

  Next, the basic operation of the mobile phone terminal 10 configured as described above and provided with the tag reader 17 will be described. FIG. 2 is a flowchart of an incoming call setting change routine executed in the mobile phone terminal 10 via the control unit. As shown in the figure, in the first step S1, an IC tag detection radio wave of a predetermined frequency band, for example 2.45 GHz, is transmitted from the antenna unit 16 to the periphery of the mobile phone terminal 10 at a predetermined time interval, for example, 5-60 seconds. . At this time, when the IC tag 20 is placed in the communicable area of the mobile phone terminal 10, an electromotive force is generated by electromagnetic induction in the antenna portion 21 of the IC tag 20, and from the antenna portion 21 to the surrounding area. An identification signal is transmitted. In the next step S2, it is determined whether or not the identification signal from the IC tag 20 arranged around can be received via the antenna unit 16, and if the identification signal is received, the process proceeds to step S3. If so, the process proceeds to step S4.

  In step S3 when the identification signal is detected, after setting the incoming mode of the mobile phone terminal 10 to the manner mode in which the mobile phone terminal 10 is notified by vibration, the process returns to the main routine for controlling the entire program of the mobile phone terminal 10. In step S4, the non-manner mode with voice transmission and ringing is set and the process returns to the main routine. In this way, based on the presence or absence of the identification signal acquired via the antenna unit 16, it is determined whether the user wearing the IC tag 20 is in the communicable area of the mobile phone terminal 10, The incoming call setting can be appropriately switched, and the manner mode is overlooked even when the user is away from the mobile phone terminal 10, or the user holds the mobile phone terminal 10 close to the user. However, it is possible to surely prevent the trouble that the non-manner mode is entered and the incoming call is notified by voice.

  3 and 4 are schematic explanatory views showing an embodiment of the mobile phone terminal 10. As shown in FIG. 3A, when the IC tag detection radio wave is transmitted from the mobile phone terminal 10 to the surroundings at a predetermined interval, and the IC tag 20 is disposed at a position where it can be received, the IC tag 20 Is activated. Thus, a predetermined identification signal stored and held in the IC tag 20 is transmitted from the antenna unit 21 of the IC tag 20 (FIG. 3B). At this time, a signal transmitted from the antenna unit 21 can be transmitted as a coded digital signal, and the signal may be transmitted to the mobile phone terminal 10 without being influenced by noise on the radio signal. The IC tag 20 is attached to a tag mounting body S. The tag mounting body S includes clothes worn by the user directly, accessories such as rings and pendants, or user clothes such as a key holder. Indirectly attached to a carried item or the like can be considered, and in any case, the IC tag 20 can be attached to the tag mounting body S by being fixedly sewn and adhered. As a result, the IC tag 20 and the user are maintained in a linked state, and the positional relationship of the user with respect to the mobile phone terminal 10 is determined with the communicable state between the IC tag 20 and the mobile phone terminal 10 as an intermediate. be able to.

  Thus, according to the present embodiment, for example, when a user who wears the IC tag 20 via the tag mounting body S while notifying the mobile phone terminal 10 on a desk or table leaves the IC Since the distance between the tag 20 and the mobile phone terminal 10 is out of the communicable area, as shown in FIG. 4, the incoming mode of the mobile phone terminal 10 is automatically set to the non-manner mode or the like, and conversely If the tag 20 is within the range of a familiar distance within the communicable area with respect to the mobile phone terminal 10, the mobile phone terminal 10 is set to the manner mode or the like. At this time, even when other IC tags are arranged around the mobile phone terminal 10, the incoming call setting is changed by detecting the presence or absence of the user's identification signal, so there is no malfunction or error. Appropriate incoming call settings will be made.

  As described above, the mobile phone terminal 10 of the present embodiment can periodically determine whether or not the IC tag 20 is within the communicable range of the mobile phone terminal 10. Corresponding incoming call settings can be made appropriately. That is, the distance between the mobile phone terminal and the user wearing the IC tag 20 is determined by attaching the IC tag 20 that transmits the identification signal to clothes worn by the user or their carry-on items. Then, when the IC tag 20 is in a range where communication from the mobile phone terminal 10 is possible, the manner mode is set, and when the identification signal from the IC tag 20 is not detected, the incoming setting change processing for setting the non-manner mode is performed. be able to. Thereby, the usability of the mobile phone terminal 10 can be further improved.

As another embodiment, the transmission mode of the mobile phone terminal 10 is automatically changed to either the transmission possible mode or the transmission disabled mode based on the presence / absence of an identification signal from the IC tag 20. be able to.
That is, the IC tag detection radio wave is transmitted from the antenna unit 16 to the periphery of the mobile phone terminal 10. At this time, when the IC tag 20 is placed in the communicable area of the mobile phone terminal 10, an electromotive force is generated by electromagnetic induction in the antenna portion 21 of the IC tag 20, and from the antenna portion 21 to the surrounding area. An identification signal is transmitted. Then, it is determined whether or not the identification signal from the IC tag 20 arranged around can be received via the antenna unit 16, and when the identification signal is received, the transmission mode of the mobile phone terminal 10 can be transmitted. On the other hand, in the case of non-reception, the mode is set to the transmission disabled mode.
In this way, if the mobile phone terminal 10 is misplaced or lost, the tag mounting body S possessed by the mobile phone terminal 10 and the terminal user has a distance that the identification signal cannot be received. Since the transmission mode is automatically switched to the transmission disabled mode, when a third party picks up the mobile phone terminal 10, an unauthorized use by the third party can be prevented beforehand.

The embodiments of the present invention are merely illustrative of specific examples thereof, and the present invention is not limited thereby. That is, the design and form of the mobile phone terminal are not limited to those shown in the embodiments. For example, each antenna in the tag reader 17 as the IC tag monitoring unit and the transmission unit 12 and the reception unit 13 as the wireless communication unit can be shared by one antenna unit. In this way, if the antenna portion is shared, the design of the conventional telephone terminal can be followed, so that the design is not impaired.
It is also possible to set the communicable distance between the IC tag 20 and the tag reader 17 within a predetermined distance range and appropriately change the cooperation distance between the tag mounting body S on which the IC tag 20 is mounted and the mobile phone terminal 10. It is.
