Description

  The present invention relates to a mobile communication terminal, and more particularly to a mobile communication terminal equipped with a wireless tag reader.

  In places and situations where it is generally undesirable to make and receive mobile phones, such as in hospitals, airplanes, movie theaters, and school classes, turn off the mobile phone and put the mobile phone into silent mode. "There are notices and announcements regarding usage restrictions. As a method for forcibly restricting incoming / outgoing calls of a mobile phone, there is an installation of a call function suppressing device such as a mobile phone that blocks the radio wave of the mobile phone with another radio wave. There is also a method of electromagnetically shielding a building or the like (see Non-Patent Document 1).

  In addition, if it is determined that it is not preferable to communicate from at least one of GPS, a mobile base station, a wireless LAN server that can currently communicate, a UWB server that is short-range wireless, and a wireless tag, it is forcibly manners A portable communication device to be set to a mode is shown (see Patent Document 1).

Ministry of Internal Affairs and Communications Postal Service Telecommunication Press Release “To prevent inconvenience of incoming / outgoing mobile phones in specific spaces” June 10, 1998, http://www.soumu.go.jp/joho_tsusin/pressrelease/japanese /denki/980610j601_1.html) JP 2005-57539 A

  In the conventional mobile phone, the user himself / herself judges the situation and needs to change the operation settings such as “turn off the power” and “set to the manner mode”. For this reason, there is a possibility that a situation in which the operation setting is not changed even though the operation setting needs to be changed may occur. As a result, there are problems such as ringing sounds during movie screenings and the like, causing inconvenience and trouble to the surroundings.

  When installing a call function suppression device such as a mobile phone, the device is realized by blocking the radio wave of a mobile phone with another radio wave, so it is difficult to install in a hospital or aircraft where radio wave transmission is not desirable There is a problem. In addition, since this device suppresses communication of mobile phones and the like, it is effective in preventing the occurrence of ringtones, but it is not useful in preventing the occurrence of alarm sounds and button confirmation sounds that are not directly related to calls / communications. There is.

  When electromagnetically shielding a building or the like, there is a problem that a large amount of cost is required for the facility of the shield and communication services including data communication cannot be permanently received in the building.

  The above-mentioned Patent Document 1 shows a portable communication device that changes the operation setting of the device in a “state where communication is not preferable”, but not only “a state where communication is not preferable” but also “generates sound”. Appropriate restrictions according to the place and situation where the terminal is used, such as “a state where it is not preferable”, “a state where transmission of radio waves is not preferable”, “a state where light emission is not preferable” are necessary.

  The present invention has been made in view of such a point, and in a situation where the operation setting of the terminal is different from the state in which the terminal should exist (contradictory), the terminal automatically sets the operation setting without requiring any user operation. An object is to provide a mobile communication terminal to be changed.

  In order to solve such a problem, the mobile communication terminal of the present invention reads IDs and information of wireless tags installed at various positions such as places or objects, and uses the information from the wireless tags as the current place or the future. The operation setting that the terminal should have in the destination is determined, and the terminal automatically changes the operation setting when it is different from the current operation setting.

  The wireless tag used by the mobile communication terminal of the present invention for determining the situation uses radio waves as information transmission means. However, since the radio tags are weak radio waves, they may be installed around equipment that may cause malfunction due to electromagnetic waves. no problem. In addition, wireless tags are sufficiently cheaper than mobile phone and other telephone call function deterrent devices and electromagnetic shields, and can be easily installed, moved, removed, and removed from places or objects. It can be set flexibly.

  In a mobile communication terminal that performs calls and communications in various places and situations, the terminal can automatically determine the surrounding situation and perform state control without user operation.

  According to the present invention, the user can use the mobile communication terminal in compliance with the terminal usage rules and manners according to the place or the situation without needing to be particularly conscious. Unlike conventional mobile communication terminals, the state control is automatically performed according to the place or situation, so that the user's usability is greatly improved.

  The mobile communication terminal according to the first embodiment of the present invention includes a reading unit that reads an ID and / or information of a wireless tag installed (attached or the like) in a certain place or object, and a wireless read by the reading unit. Based on the information from the tag and the current state of the terminal, the status determination means for determining the operation setting that the terminal should be, and the operation setting that the terminal should have determined and the current operation setting determined by this status determination means A difference determination unit that determines a difference between them, and an operation control unit that changes operation settings in a direction to eliminate the difference (decrease the difference) when the difference determination unit determines that there is a difference. If the wireless tag contains information such as terminal usage rules and manners at the current location, the information is extracted.

  Thus, even if the user does not know or forget the terminal usage rules and manners at the current position, the terminal is automatically changed to an appropriate operation setting, so that the rules and manners can be observed. The wireless tag stores terminal usage rules and manner information. For example, if you install a wireless tag that stores information that "the device must be turned off" in the priority seat of the train, the device will automatically turn off when the user approaches the priority seat. You can protect your manners.

  In the second embodiment of the present invention, in the portable communication terminal according to the first embodiment, after changing the operation setting triggered by reading of the wireless tag, the reading unit continues to check the presence of the wireless tag. Thus, when a predetermined time based on a value set in advance by the user has elapsed since the presence of the wireless tag can no longer be confirmed, a process for returning the operation setting to the state before the change is performed.

  As a result, when the use restriction is released, the terminal automatically returns to the original operation setting, so that no user operation is required. For example, if a wireless tag that stores information that "the device must be turned off" is installed in the priority seat of a train, the power is automatically turned on when the user leaves the priority seat, and the use is resumed. it can.

  In the mobile communication terminal according to the first embodiment, the third embodiment of the present invention, when reading a plurality of wireless tags within a predetermined time by the reading means, the reading order of the read wireless tags, Based on the reading time interval, information on each wireless tag, and the current state of the terminal, there is a situation determination means for determining the operation setting that should be inferred from the terminal trend. As a result, the terminal can grasp the user's moving direction, and can determine the terminal usage rules and manners at the current position and the moving destination based on information from the plurality of wireless tags.

  For example, wireless tags that store information such as “outside the hospital” and “inside the hospital” are installed on the outside and inside of the building at the entrance of the hospital. “Do not transmit radio waves inside the hospital.” If there is a terminal usage rule, and when reading from the outer wireless tag in the order of the inner wireless tag, it is determined that “the user enters the hospital” and state control such as turning off the power is performed. When reading in order from the inside to the outside, it is possible to perform a series of state control without making the user aware of it, such as returning to the state before entering the hospital by judging that the user leaves the hospital. .

  According to a fourth embodiment of the present invention, in the mobile communication terminal according to the first to third embodiments, additional information outside the wireless tag is obtained from the ID or information of the wireless tag read by the reading unit. And a network for obtaining additional information from another apparatus based on the ID of the wireless tag via the network when the information determining means determines that additional information exists. Communication means are provided.

  As a result, information that is not built in the wireless tag can be obtained separately as additional information, so that the situation determination means can be performed more precisely. Further, since the information can be obtained as newer information than the information built in the wireless tag, it is possible to appropriately determine the situation even when the terminal usage rules and manners are updated after the wireless tag is installed.

  In the fifth embodiment of the present invention, in the portable communication terminal according to the fourth embodiment, the database for storing the ID and information of the wireless tag read by the reading means and the additional information obtained by the network communication means And information collating means for investigating whether the ID of the wireless tag exists in the database, and information updating means for updating the database with the information obtained by the reading means and the network communication means. If the ID is found to exist, the information corresponding to the ID is extracted from the database and reused, so that the reading means, the information judging means and the network communication means can be omitted. Thereby, the time required for obtaining information from the wireless tag can be shortened. Also, there is no need to pay a communication fee or network usage fee for obtaining additional information. Further, since the user's action range and action pattern are fixed to some extent in daily life, the wireless tags encountered are limited to some extent. When the user carries the portable communication terminal according to the present invention and acts for a few days, most of the wireless tags existing within the user's action range are stored in the database, so that terminal control is quickly performed. To go. Further, terminal control can be performed more quickly by sorting / optimizing the records in the database according to the number of times of inquiries and the number of times of actual use for changing operation settings.

  The sixth embodiment of the present invention suspends the network communication means in the portable communication terminal according to the fifth embodiment when the network communication means cannot be executed due to out of communication range or the like. Then, after the situation determination means, the network communication means is resumed and the information update means is executed when the network communication means enters the communication range and becomes executable.

  Thus, when a wireless tag installed outside the network communication area is encountered again, additional information can be obtained quickly and reliably from the terminal database.

  According to a seventh embodiment of the present invention, in the portable communication terminal according to the fifth embodiment, information obtained by exchanging information with a wireless tag ID and information without using the reading means described above. An exchange means is provided.

  As a result, the user can obtain in advance information such as terminal usage rules and manners at the destination, and terminal control can be performed quickly and reliably at the destination.

  According to an eighth embodiment of the present invention, in the mobile communication terminal according to the seventh embodiment, the information exchanging means is an electronic mail, a mobile phone mail, an HTTP, an FTP, a local and a short distance which is an Internet communication. At least one of barcodes, memory cards, cable communications, infrared communications, BlueTooth, UWB, wireless PAN, wireless LAN, FM multiplex broadcasting, terrestrial digital broadcasting, and BS / CS digital broadcasting for transmitting information over a wide area Exchange information through one.

  Thereby, the user can obtain information on the wireless tag through various media. For example, wireless tag information encountered at a travel destination is obtained at a store of a travel agency that has made a travel reservation, and concert site wireless tag information is obtained from a kiosk terminal from which a ticket was purchased.

  Hereinafter, more specific examples regarding the mobile communication terminal according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an external configuration of a mobile communication terminal according to an embodiment of the present invention. As shown in FIG. 1, a speaker unit 101 for outputting sound is provided at the upper end of the foldable portable communication terminal 100 according to the present embodiment. In addition, a microphone unit 102 for inputting voice is provided at the lower end of the mobile communication terminal 100.

  Further, the lower half of the mobile communication terminal 100 is provided with a man-machine interface unit 103 such as a numeric keypad and a direction key for a user to input information. Furthermore, a display unit 104 for displaying information is provided in the upper half of the mobile communication terminal 100.

  A connection terminal 105 for connecting a cable to exchange information with other devices is provided at the lower end of the mobile communication terminal 100. In the center of the upper end of the mobile communication terminal 100, an infrared interface 106 for exchanging information with other devices by infrared communication is provided. An antenna 107 for transmitting and receiving radio signals is provided on the left of the upper end of the mobile communication terminal 100 in order to communicate with the radio tag and other devices.

  Next, an internal configuration example of the mobile communication terminal 100 will be described with reference to FIG. FIG. 2 is a functional block diagram illustrating an internal configuration example of the mobile communication terminal 100 according to the present embodiment. In addition, the same code | symbol is added to the part same as the part already demonstrated.

  The mobile communication terminal 100 is provided with a terminal control unit 201 that controls the entire terminal. The terminal control unit 201 includes a CPU and peripheral circuits such as a memory (ROM, RAM) and a timer. The mobile communication terminal 100 includes a wireless tag reader unit 202 that exchanges information with a wireless tag via a wireless tag reader antenna 203, and a network communication unit 204 that communicates with other devices via a network communication antenna 205. And a wireless communication unit 208 that communicates with the communication terminal via the wireless communication antenna 209. Note that the wireless tag reader antenna 203, the network communication antenna 205, and the wireless communication antenna 209 can be realized by being stretched around the casing of the mobile communication terminal 100 or integrated with the antenna 107.

  In addition, the mobile communication terminal 100 is provided with a database unit 206 that stores information on the wireless tag. The database unit 206 can be realized as an independent module, or can be realized by a CPU and a memory built in the terminal control unit 201. The mobile communication terminal 100 is provided with a local communication unit 207 that exchanges information with other devices via the connection terminal 105 or the infrared interface 106. The wireless tag stores regulations, rules, etc. (hereinafter referred to as “terminal regulation information”) related to the use (setting) of the mobile terminal related to the installation position.

  Next, the operation of the mobile communication terminal 100 will be described with reference to FIGS. FIG. 3 is a flowchart showing the flow of control of the mobile communication terminal according to the present embodiment, which is divided into three parts (FIGS. 3 to 5) along the flow. It has become.

  FIG. 3 shown as the first part is a flowchart showing an operation flow from reading of the wireless tag to acquisition of information. This will be described with reference to FIG.

  First, processing is started (start), and variables and timers used in terminal control processing are initialized when the terminal is powered on (step ST300). The “existing ID” variable stores the ID of the wireless tag used for the previous situation determination. The “number of tags” variable stores the number of wireless tags read during the timer 1 operation. The “hold ID” variable stores the ID of the wireless tag for which communication cannot be performed and additional information is reserved. The “change mode” variable stores the state when the operation setting is changed. For example, “single” value is stored if the wireless tag that caused the operation change is single (one), “multiple” value is stored if it is plural (two or more), and the operation is changed as a result of the difference determination. When no longer needed, “None” value is stored. The timer 1 is used to count the number of wireless tags read within a certain time. The timer 2 is used to monitor the wireless tag that has caused the operation setting change.

  Next, the wireless tag reader unit 202 investigates whether or not a wireless tag exists within the communication range (step ST301). If the presence of the wireless tag is recognized in step ST301, the wireless tag reader unit 202 reads the wireless tag ID (step ST302). Next, the read ID is compared with the “existing ID” variable value (ST303).

  In step ST303, if the IDs are equal (Yes), it is determined that the situation has not changed, the timer 2 is stopped to reset the operation setting return process (step ST304), and the process returns to step ST301. On the other hand, if the IDs are different in step ST303 (No), it is determined that a new wireless tag has been encountered, and the process proceeds to step ST305. The state of the timer 1 is determined in order to count the number of wireless tags read within a certain time (step ST305). In Step ST305, when it is determined that the timer 1 is stopped or timed out, it is determined that the newly encountered wireless tag is the first one, and measurement by the timer 1 is started so that the counting can be performed (Step S305). (ST306) In step S307, the “number of tags” variable is set to 0, and the process proceeds to step ST308. On the other hand, when the timer 1 is operating in step ST305 (Else), it is determined that the newly encountered wireless tag is the second or later, and the process proceeds to step ST308 without performing anything. Next, 1 is added to the “number of tags” variable (step ST308).

  Next, in preparation for subsequent processing, the ID value of the wireless tag, the “number of tags” variable value, and the time value of timer 1 are combined and recorded in a memory built in terminal control section 201 (step ST309). . In addition, since the information of a plurality of wireless tags may be used in the subsequent processing, recording is performed sequentially while changing the recording area (address) so that the old value is not overwritten. Next, it is verified whether or not the read ID is stored in the database unit 206 (step ST310). If it is determined in step ST310 that an ID is stored (hit), terminal restriction information corresponding to the ID is extracted from the database unit 206 (step ST317). On the other hand, if it is determined in step ST310 that the ID is not stored (miss), the wireless tag reader unit 202 reads the terminal restriction information built into the wireless tag (step ST311). Since there is a wireless tag that contains only an ID, the processing in step ST311 is omitted in that case. Next, based on the ID and the information read in step ST311, it is determined whether or not additional information exists outside the wireless tag (step ST312). If it is determined in step ST312 that there is additional information, another device is accessed via the network communication unit 204 and an attempt is made to obtain additional information on the wireless tag (step ST313). Note that when the wireless communication unit 208 can access other devices and obtain additional information, the wireless communication unit 208 may be used as an obtaining unit.

  Next, it is determined whether or not the acquisition of additional information in step ST313 is successful (step ST314). If it is determined in step ST314 that the acquisition is successful (Yes), the information built in the wireless tag and the additional information outside the wireless tag are stored in the database unit 206 in association with the ID of the wireless tag (step ST316). Information necessary for subsequent processing is recorded in a memory built in the terminal control unit 201 in association with the ID value of the wireless tag.

  On the other hand, if it is determined in step ST314 that the acquisition has failed (No), the acquisition process is suspended and the ID is stored in the “suspend ID” variable so that it can be resumed later (step ST315). Is stored in the database unit 206 in association with the ID of the wireless tag (step ST316). Information necessary for subsequent processing is recorded in a memory built in the terminal control unit 201 in association with the ID value of the wireless tag.

  When the process proceeds to step ST316 or step ST317, acquisition of terminal restriction information of the wireless tag existing within the communication range of the wireless tag reader unit 202 is completed (step ST318).

  As a second part, the flow of operations from situation determination to operation control will be described with reference to FIG.

  First, the process leaves step ST318, and the ID of the wireless tag read immediately before is stored in the “existing ID” variable as a preparation for the situation determination process (step ST321). By using this variable, it is possible to prevent the same wireless tag from being processed many times.

  Next, based on the terminal restriction information of one or more wireless tags recorded in the memory and the current terminal operation setting managed by the terminal control unit 201, the operation setting that the terminal should be in is determined. (Step ST322).

  Next, the difference between the operation setting of the terminal determined in step ST322 and the current operation setting is determined (step ST323). Even if there is a difference in operation settings, it may be determined that there is no difference if the degree is small. For example, when the current operation setting is “light emission on incoming call” and the restriction at that position imposed on the user based on the terminal restriction information is “light emission is not preferred” and the recommended level content, It may be judged that there is no difference by checking with the policy set in. Here, the policy is a collection of rules that summarize terminal usage rules and manners corresponding to manners according to places or situations. In the policy, rules established by terminal manufacturers, industry groups, communication carriers, national organizations and the like are set in advance. In the above example, it is assumed that the policy is set to “ignore the recommended light emission limit”. The user may be able to change the rules freely for the portions that do not require strict restrictions in the policy.

  Next, it is determined whether or not to change the setting based on the determination content in step ST323 (step ST324). If it is determined in step ST324 that the setting is to be changed (Yes), the number of wireless tags used for the determination in ST322 and ST323 is determined as preparation for the operation setting return processing (step ST325).

  On the other hand, if it is determined in ST324 that the setting is not changed (No), the “change mode” variable is set to “None” (step ST326), and the operation control is completed (ST320).

  If it is determined in step ST325 that the number of wireless tags used for the determination is singular, a “single” value is set in the “change mode” variable (step ST327).

  On the other hand, when it is determined in step ST325 that the number of wireless tags is plural, a “multiple” value is set in the “change mode” variable (step ST328) After step ST327 or ST328, the operation setting of the terminal is performed. The operation setting of the terminal determined in ST322 is changed (step ST329), and the operation control is completed (step ST320) Next, after exiting step ST320 and returning to step ST301 in FIG. Repeat the process from reading to operation control.

  FIG. 5 described as the third part is a flowchart showing the flow of operations related to network communication suspension and operation setting return. In step ST301, when the presence of the wireless tag is not recognized within the communication range of the wireless tag reader unit 202 (Else), the process proceeds to step ST319 (B), and some processes are performed. First, network communication suspension processing is performed. It is determined whether or not the value of the “hold ID” variable is other than 0 (ST330). In step ST330, when it is determined that the value of the “hold ID” variable is other than 0, another device is accessed via the network communication unit 204, and an addition related to the ID stored in the “hold ID” variable. An attempt is made to obtain information (step ST331).

  Next, it is determined whether or not the acquisition of additional information in step ST331 is successful (step ST332). If it is determined in step ST332 that the acquisition is successful (Yes), the acquired additional information is stored (updated) in the database unit 206 in association with the ID stored in the “hold ID” variable (step ST333). The value of the “hold ID” variable is set to 0 (step ST334), and the process proceeds to step ST335. On the other hand, if it is determined in ST332 that the acquisition has failed (No), the acquisition process is suspended and the process proceeds to step ST335. If acquisition failures continue, the number of failures set in advance will be exceeded, or the value of the “pending ID” variable will be forcibly set to 0 when a preset time has passed. Information acquisition may be interrupted.

  On the other hand, if it is determined in step ST330 that the value of the hold ID variable is 0 (No), the process proceeds to step ST335. Next, operation setting return processing is performed. It is determined whether or not it is “single” (step ST335) .If it is determined that it is “single” in step ST335 (Yes), the presence of the wireless tag that has caused the operation setting change is recognized. In order to check the elapsed time since the time has elapsed, the timer 2 state is determined (step ST336). On the other hand, if it is determined in step ST335 that it is other than simple (No), the process proceeds to step ST320. .

  In step ST336, when it is determined that the timer 2 is stopped (stopped), it is determined that the wireless tag has passed through STST336 for the first time after the presence of the wireless tag is not recognized, and the elapsed time is measured. Timer 2 is started (step ST337).

  On the other hand, if it is determined in step ST336 that the timer 2 has timed out, it is determined that a certain time has elapsed since the presence of the wireless tag is not recognized, and the operation setting return process is started. First, the timer 2 is stopped (step ST338), 0 is set to the “existing ID” variable (step ST339), “None” is set to the change mode variable (step ST340), and the operation setting of the terminal is changed. Return to the previous state (step ST341) After the return, the process proceeds to step ST320.

  On the other hand, if it is determined in step ST336 that the timer 2 is neither stopped nor timed out, nothing is performed and the process proceeds to step ST320. After exiting step ST320 and returning to step ST301, the processing is repeated.

  In this way, the mobile communication terminal 100 according to the present embodiment appropriately controls the operation setting of the terminal based on the terminal restriction information from the wireless tag. Thereby, even if the user does not know or forget the terminal usage rules and manners at the current position, the operation settings are automatically changed, and the rules and manners can be observed.

  As described above, according to the wireless communication terminal according to the embodiment of the present invention, the user does not need to be particularly conscious and uses the mobile communication terminal in compliance with the terminal usage rules and manners according to the place or the situation. be able to. Unlike conventional mobile communication terminals, state control is automatically performed according to the location or situation, so that the user's convenience is greatly improved.

  In the above embodiment, the example in which the restriction information of the wireless communication terminal is stored in the wireless tag has been described, but other short-distance communication means such as infrared communication may be used.
