Description

  The present invention relates to, for example, a mobile communication terminal, an information providing method, and an information providing program that select any one of a plurality of preset operation modes and wirelessly perform data communication.

  In recent years, mobile communication terminals having various functions such as tablet terminals have become widespread. As a method of performing data communication using such a mobile communication terminal, for example, a method of transmitting and receiving data via an access point connected to the Internet is widely adopted.

  Here, for example, a wireless local area network (LAN) or a wired LAN is used for communication connection between the access point and the mobile communication terminal. Comparing the wireless LAN and the wired LAN, the wireless LAN is superior to the wired LAN in that data communication can be performed at any place because there is no need to perform cable wiring. For this reason, the wireless LAN communication function is installed in many mobile communication terminals such as the above-described tablet terminals, and is widely used for communication between the mobile communication terminal and the access point.

  A general mobile communication terminal equipped with a wireless LAN communication function is configured to display radio wave intensity on a display unit such as a liquid crystal display device. For this reason, the user of the mobile communication terminal can know the radio field intensity at the current location from the display on the display unit, so that data communication can be performed by moving the location as necessary while viewing the radio field intensity.

  For example, Patent Literature 1 discloses a technique for searching for a place where reception quality is improved using a map in which reception quality of a radio signal is associated with position information.

  However, in wireless LAN communication, even in places where the radio field intensity is high, the throughput (Through put) value may be significantly reduced due to the influence of a fading phenomenon or the like. As described above, when a large amount of data is to be downloaded using a wireless LAN communication function in a place where the throughput value is low, it may take a long time to complete the download. Also, depending on the operation mode of the wireless LAN communication function, it may take a long time to download. For example, in the case of an operation mode corresponding to the IEEE (The Institute of Electrical and Electronics Engineers, Inc.) standard, the frequency band and the nominal speed are different at 802.11a / b / g / n. The technique described in Patent Document 1 does not support a plurality of operation modes of the wireless LAN communication function.

  The present invention has been made in view of such circumstances, and provides a technique capable of easily providing information suitable for the current location and operation mode of a mobile communication terminal when attempting to perform data communication wirelessly.

  The mobile communication terminal of the present invention is a mobile communication terminal that performs data communication wirelessly by selecting one of a plurality of operation modes provided in advance, and the position information of the mobile communication terminal is used as terminal position information. Measured by a location information acquisition unit to be acquired, a throughput measurement unit that measures a throughput value that is an effective transfer amount per unit time, while the mobile communication terminal performs data communication by radio, and the throughput measurement unit A storage unit that stores the throughput value, the terminal position information acquired when the throughput value is measured, and the operation mode selected when the throughput value is measured, as communication state information in association with each other; The terminal location information acquired by the location information acquisition unit when the mobile communication terminal tries to perform data communication wirelessly.

The wireless LAN communication unit 200 is connected to the control unit 500. The wireless LAN communication unit 200 passes through the wireless LAN communication antenna 100 according to an operation mode (for example, an operation mode corresponding to any of IEEE802.11a / b / g / n) set by an operation mode setting unit 510 described later. Then, data communication is performed with the access point 2000 (see FIG. 2).

  A GPS (Global Positioning System) communication antenna 300 is an antenna suitable for GPS communication, and is connected to the GPS communication unit 400. The GPS communication unit 400 is connected to the control unit 500 and receives a signal (hereinafter referred to as a GPS signal) from a GPS satellite via the GPS communication antenna 300.

  The control unit 500 includes mobile communication terminals such as a wireless LAN communication antenna 100, a wireless LAN communication unit 200, a GPS communication antenna 300, a GPS communication unit 400, a storage unit 600, an operation unit 700, a display unit 800, and an electronic compass unit 900.

  The control unit 500 includes an operation mode setting unit 510, a position information acquisition unit 520, a throughput measurement unit 530, an information detection unit 540, and an information provision unit 550.

  Operation mode setting unit 510 selects one of a plurality of operation modes of a plurality of wireless LAN communication functions provided in advance. As described above, the operation modes of the plurality of wireless LAN communication functions correspond to the four standards of IEEE 802.11a / b / g / n. The operation mode setting unit 510 selects one of the four operation modes. The operation mode setting unit 510 selects an operation mode based on a signal input by the user of the mobile communication terminal 1000 through the operation unit 700. That is, the operation mode setting unit 510 selects one of the operation modes corresponding to the four standards of IEEE802.11a / b / g / n based on a signal input from the operation unit 700 by the user.

  The location information acquisition unit 520 acquires location information of the mobile communication terminal 1000 as terminal location information. Specifically, the position information acquisition unit 520 acquires the latitude and longitude of the mobile communication terminal 1000 as terminal position information from the GPS signal received by the GPS communication unit 400.

  The throughput measuring unit 530 measures a throughput value while the mobile communication terminal 1000 performs wireless data communication using the wireless LAN communication unit 200 and the wireless LAN antenna 100. Here, the throughput value refers to the effective transfer amount per unit time. Specifically, the throughput measuring unit 530 calculates a throughput value based on the time during which data communication is performed and the file capacity of the communicated data.

  The information detection unit 540 detects the communication state information 610 stored in the storage unit 600 based on a predetermined condition. Note that specific functions, operations, and the like of the information detection unit 504 will be described in detail in the operation description described later.

  The information providing unit 550 provides information related to communication state information based on the detection result of the information detecting unit 540. Note that specific functions and operations of the information providing unit 550 will be described in detail in the operation description described later.

  The storage unit 600 is connected to the control unit 500 and stores one or more pieces of communication state information 610. The communication state information 610 is information in which the terminal position information 610a, the operation mode 610b, and the throughput value 610c are associated with each other. The throughput value 610c at this time is a throughput value measured by the throughput measuring unit 530 while the mobile communication terminal 1000 is performing data communication wirelessly. The terminal position information 610 a is terminal position information acquired when the throughput value 610 c is measured by the throughput measuring unit 530. The operation mode 610b is an operation mode that was selected when the throughput measurement unit 530 measured the throughput value 610c.

  FIG. 4 shows information stored in the storage unit 600. As shown in FIG. 4, for example, terminal location information 610a (latitude / longitude = XXXA / YYA), throughput value 610c (ZZA Mbps (bit per second)), and operation mode 610b (IEEE802.11g) They are associated with each other and stored as communication state information 610-1. Similarly, terminal position information 610a (latitude / longitude = XXXB / YYYB), throughput value 610c (ZZB (Mbps)), and operation mode 610b (IEEE802.11g) are associated with each other, and communication state information 610 -2 is stored. In this way, the storage unit 600 includes a plurality of pieces of communication state information 610-1, 610-2, 610-3,..., 610-n, terminal location information 610a, throughput value 610c, and operation mode 610b. They are stored in a form that is associated with each other. In the following description, the communication status information 610-1, 610-1, n, unless otherwise required to distinguish each of the communication status information 610-1, 610-2, 610-3,. Each of 610-2, 610-3, ..., 610-n is simply referred to as communication state information 610.

  Returning to FIG. 1, the operation unit 700 is, for example, a switch button, and is provided on the surface of the mobile communication terminal 1000, for example, as shown in FIG. The operation unit 700 is connected to the control unit 500. A user of the mobile communication terminal 1000 uses the operation unit 700 to input desired information as a signal. For example, the user of the mobile communication terminal 1000 can input an operation mode using the operation unit 700. As a result, the operation mode setting unit 510 acquires the signal input from the operation unit 700, and sets one of the four operation modes corresponding to IEEE 802.11a / b / g / n based on the acquired signal. To do.

  The display unit 800 displays each processing content executed by each unit in the control unit 500. For example, the display unit 800 displays information provided by the information providing unit 560 under the control of the control unit 500. For example, a liquid crystal display element or an organic EL (Electro-Luminescence) display element is used for the display unit 800.

  The electronic compass unit 900 acquires a terminal direction that is the direction in which the mobile communication terminal 1000 is facing while the mobile communication terminal 1000 is performing data communication wirelessly. The terminal direction is a direction in which the reference plane of the mobile communication terminal 1000 faces. For example, in FIG. 2, the side surface on the upper side of the paper surface is used as a reference surface, and the direction of arrow A toward the side surface on the upper side of the paper surface is used as the terminal direction. The electronic compass unit 900 corresponds to the compass unit of the present invention.

  The configuration of the mobile communication terminal 1000 according to the first embodiment of the present invention has been described above.

  Next, operation | movement of the mobile communication terminal 1000 concerning the 1st Embodiment of this invention is demonstrated based on figures. FIG. 5 shows an operation flow of the mobile communication terminal 1000.

  As shown in FIG. 5, in order to perform data communication via the access point 2000, when a user of the mobile communication terminal 1000 inputs a predetermined command signal using the operation unit 700 (S 501), the position information acquisition unit 520. The terminal position information (latitude, longitude) is acquired from the GPS signal received by the GPS communication unit 400 (S502).

  Here, the terminal position information acquired by the position information acquisition unit 520 when the mobile communication terminal 1000 tries to perform data communication wirelessly is referred to as “current terminal position information”. This current terminal location information substantially corresponds to the location information (latitude, longitude) of the current location of the mobile communication terminal 1000, and is acquired by the processing of S502. In addition, the operation mode selected when the mobile communication terminal 1000 tried to perform data communication wirelessly is referred to as a “selected operation mode”.

  After the processing of S502, the information detection unit 540 detects the communication state information 610 stored in the storage unit 600 based on the current terminal position information and the selection operation mode. Specifically, first, the information detection unit 540 stores communication state information including terminal position information within a predetermined range (for example, within 10 km) from the current location of the mobile communication terminal 1000 (the position indicated by the current terminal position information). Whether it is stored in 600 is detected (S503).

  When the information detection unit 540 detects that the communication state information satisfying the above condition is stored in the storage unit 600 (S503, YES), the throughput is higher than the throughput value included in the detected communication state information. It is determined whether or not communication state information including a value and including the same operation mode as the selected operation mode is stored in the storage unit 600 (S504).

  When it is detected that communication state information including a throughput value higher than the throughput value included in the communication state information detected in S504 and including the same operation mode as the selected operation mode is stored in the storage unit 600 (S504, YES), the information providing unit 550 acquires terminal position information (latitude, longitude) in the communication state information including the highest throughput value among the detected communication state information (S505). As a result, the mobile communication terminal 1000 uses the communication state information having the highest throughput value among the communication state information including the throughput value higher than the current location of the mobile communication terminal 1000 under the same operation mode as the selected operation mode. The included terminal location information (latitude, longitude) can be acquired.

  Next, the electronic compass unit 900 acquires a terminal direction under the control of the control unit 500 (S506). Further, the information providing unit 550 calculates a movement distance and a movement direction from the current location to the position indicated by the terminal position information acquired in S505 (S507). That is, more specifically, the information providing unit 550 determines the position (mobile communication) indicated by the current terminal position information based on the current terminal position information, the terminal position information acquired in S505, and the terminal direction acquired in S506. The moving distance and moving direction from the current location of the terminal 1000 to the position indicated by the terminal position information acquired in S505 are calculated.

  Then, the information providing unit 550 provides the result (movement distance and movement direction) calculated in S507 to the user of the mobile communication terminal 1000 by displaying the result on the display unit 800, for example (S508). In addition, although it demonstrated that the said calculation result was provided by the display on the display part 800 here, you may provide the said calculation result with an audio | voice, for example. In addition, the information providing unit 550 may provide only the moving distance or only the moving direction instead of providing both the moving distance to the moving destination and the moving direction. In the case where the information providing unit 559 provides only the movement distance to the destination, the electronic compass unit 900 is not necessary in this embodiment.

  Next, the display unit 800 displays “data communication starts” and “OK button” in accordance with an instruction from the control unit 500 (S509).

  As the user of the mobile communication terminal 1000 moves as necessary, the mobile communication terminal 1000 moves (S510). That is, the user of the mobile communication terminal 1000 moves to a position with the highest throughput value, for example, according to the distance and moving direction provided in S507. As a result, the mobile communication terminal 1000 is arranged at a position with the highest throughput value.

  When the user of the mobile communication terminal 1000 confirms the display content on the display unit 600 and presses the “OK button”, the wireless LAN communication unit 200 of the mobile communication terminal 1000 starts data communication via the access point 2000. (S511). In this case, a touch panel switch is attached to the surface of the display unit 800, and a command signal for starting data communication is output from the control unit 500 to the wireless LAN communication unit 200 by pressing the “OK button”. Shall be.

  Next, the throughput measuring unit 530 measures a throughput value from the start to completion of data communication (S512). Specifically, the throughput measurement unit 530 calculates the throughput value based on the time from when the “OK button” is pressed until the data communication is completed and the file capacity of the communicated data. At this time, the position information acquisition unit 520 acquires terminal position information when the throughput value is measured. In addition, the control unit 500 acquires an operation mode when the throughput value is measured.

  Then, the control unit 500 stores the terminal position information (latitude, longitude), the throughput value, and the operation mode in the storage unit 600 as the communication state information 610 (S513). More specifically, the control unit 500 acquires the throughput value 610c measured by the throughput measurement unit 530 and the throughput value while the mobile communication terminal 1000 performs wireless data communication. The terminal position information 610a and the operation mode 610b selected when the throughput value is measured are stored as communication state information 610 in association with each other. At this time, the data measured in S512 is used as the throughput value 610c. Further, as the terminal position information 610a, when the mobile communication terminal 1000 moves in S510, the terminal position information when the throughput value is measured in S512 is used. If the user of the mobile communication terminal 1000 does not move in S510, the current terminal location information acquired in S502 may be used as the terminal location information 610a. Further, as the operation mode 610b, the mode selected when the throughput value is measured in S512 is used. Thereby, the mobile communication terminal 1000 can store the throughput value 610c, the terminal position information 610a (latitude, longitude), and the operation mode 610b in the data storage unit 600 in association with each other. it can.

  Returning to S503, when the information detection unit 540 detects that communication state information including terminal position information within a predetermined range from the current location is not stored in the storage unit 600 (S503, NO), the mobile communication terminal 1000 The processing after S509 is performed without performing the processing of S504 to S508.

  In the process of S504, communication state information including a throughput value higher than the throughput value included in the communication state information detected in S504 and including the same operation mode as the selected operation mode is stored in the storage unit 600. If it is determined that it is not present (S504, NO), the mobile communication terminal 1000 performs the processing from S509 onward without performing the processing of S505 to S508.

  That is, when the information detection unit 540 detects that communication state information including terminal position information within a predetermined range from the current location is not stored in the storage unit 600 (S503, NO), or the communication state information detected in S504 If it is determined that communication state information that includes a higher throughput value than the selected operation mode and that includes the same operation mode as the selected operation mode is not stored in the storage unit 600 (NO in S504), The mobile communication terminal 1000 displays a message prompting data communication in S509 without providing the user with the information stored in the storage unit 600. Then, after the user of the mobile communication terminal 1000 moves as necessary (S510), when data communication is performed (S511), the mobile communication terminal 1000 measures the throughput value (S512) and performs data communication. The terminal position information, the throughput value, and the operation mode at the time of performing are newly stored in the storage unit 600 in association with each other.

  As described above, the mobile communication terminal 1000 according to the first embodiment of the present invention selects one of a plurality of operation modes (for example, IEEE802.11a / b / g / n) provided in advance. Then, data communication is performed wirelessly. The mobile communication terminal 1000 includes a position information acquisition unit 520, a throughput measurement unit 530, a storage unit 600, an information detection unit 540, and an information provision unit 550. The location information acquisition unit 520 acquires location information of the mobile communication terminal 1000 as terminal location information. The throughput measuring unit 530 measures a throughput value, which is an effective transfer amount per unit time, while the mobile communication terminal 1000 performs wireless data communication. The storage unit 600 stores the throughput value 610c measured by the throughput measurement unit 530, the terminal position information 610a acquired when the throughput value 610c is measured, and the operation mode 610b selected when the throughput value 610c is measured. And stored as communication state information 610 in association with each other. The information detection unit 540 includes the current terminal position information, which is terminal position information acquired by the position information acquisition unit 520 when the mobile communication terminal 1000 tries to perform data communication wirelessly, and the mobile communication terminal 1000 performs data communication wirelessly. The communication state information 610 stored in the storage unit 600 is detected based on the selected operation mode that is the operation mode selected when the user tried to perform the operation. Based on the detection result of the information detection unit 540, the information providing unit 550 provides the communication status information 610 (for example, the moving distance and moving direction from the current location to a location with a high throughput value).

  As described above, in the storage unit 600, the terminal position information 610a, the throughput value 610c, and the operation mode 610b are stored in advance in association with each other as the communication state information 610. For this reason, if any of the terminal position information 610a, the throughput value 610c, and the operation mode 610b is known, the communication status information 610 can be detected from the storage unit 600 based on the information. Further, when the mobile communication terminal 1000 tries to perform data communication by radio, the information detection unit 540 has selected the current terminal position information that substantially represents the current location of the mobile communication terminal 1000 at that time and the current position information. The communication state information 610 in the storage unit 600 is detected based on the selected operation mode representing the selected operation mode. Thereby, when it is going to perform data communication by radio | wireless, the information suitable for the present location and operation mode of a mobile communication terminal can be detected from the memory | storage part 600. FIG. Then, the information providing unit 550 provides information on the communication status information 610 based on the detection result (for example, the moving distance and moving direction from the current position to the place where the throughput value is high), so that the current position and operation mode of the mobile communication terminal Various types of suitable information are provided to the user of the mobile communication terminal 1000. As a result, it is possible to obtain the mobile communication terminal 1000 that can easily provide information suitable for the current location and operation mode of the mobile communication terminal when attempting to perform data communication wirelessly. In the present invention, the information detection unit 540 detects the communication state information 610 in the storage unit 600 in consideration of the selected operation mode, so that not only the current location of the mobile communication terminal 1000 but also a plurality of operation modes are specified. Information suitable for the operation mode can be detected and provided. By receiving the provision of such information, the user of the mobile communication terminal 1000 is based on the information notified by the information notification unit 550, for example, in which part of the indoor communicable area the throughput value is high. Can know. In addition, the user of the mobile communication terminal 1000 moves to a position where the throughput value is high as necessary, for example, when downloading a large amount of data, based on the information notified by the information notification unit 550, and performs data communication. Can do. As a result, the time until the download is completed can be shortened.

  When data is transmitted using the wireless LAN communication function, communication information suitable for the current location and operation mode of the mobile communication terminal 1000 is obtained from, for example, an access point or a server connected to the access point. A method of obtaining is also conceivable. However, before the mobile communication terminal 1000 attempts to transmit data using the wireless LAN communication function, it is necessary to inquire communication information from the mobile communication terminal 1000 to the access point or server, and complicated preprocessing is required. . On the other hand, in mobile communication terminal 1000 in the first embodiment of the present invention, as described above, terminal location information 610a, operation mode 610b, and throughput value 610c are stored as communication status information 610 in storage unit 600 in mobile communication terminal 1000. Therefore, it is not necessary to inquire communication information to an access point or a server, and information suitable for the current location and operation mode of the mobile communication terminal 1000 can be easily provided.

  Moreover, in the mobile communication terminal 1000 according to the first embodiment of the present invention, the information detection unit 540 stores communication state information including terminal position information indicating a position within a predetermined range from the position indicated by the current terminal position information. Communication state information including a throughput value higher than the throughput value included in the detected communication state information and including the same operation mode as the selected operation mode is stored. It is determined whether or not it is stored in unit 600.

  In this way, the information detection unit 540 first not only includes the communication state information including the terminal position information indicating the same position as the current terminal position information, but also the terminal position indicating a position within a predetermined range from the position indicated by the current terminal position information. Whether or not the communication state information including the information is stored in the storage unit 600 is detected. Thereby, the information detection unit 540 can detect communication state information regarding the range reaching the periphery of the current location of the mobile communication terminal 1000 from the storage unit 600. Since the current terminal position information substantially indicating the current location of the mobile communication terminal 1000 is specified by the latitude and longitude, the probability that the current terminal position information completely matches the various information stored in the storage unit 600 is very high. Very low. On the other hand, in the present invention, communication state information including terminal position information from the position indicated by the current terminal position information to within a predetermined range is set as a detection target of the information detection unit 540. For this reason, the probability that the information detection part 540 detects communication state information from the memory | storage part 600 can be raised. Furthermore, the information detection unit 540 stores in the storage unit 600 communication state information including a throughput value higher than the throughput value included in the detected communication state information and including the same operation mode as the selected operation mode. It is determined whether or not it is stored. Thereby, the information detection unit 540 can detect communication state information including a higher throughput value than the current location of the mobile communication terminal 1000 from the storage unit 600 under the condition of the same selection mode.

  Moreover, in the mobile communication terminal 1000 according to the first embodiment of the present invention, the information detection unit 540 includes a throughput value higher than the throughput value included in the detected communication state information, and is the same as the selected operation mode.

<Second Embodiment>
Next, the mobile communication terminal according to the second embodiment will be described. The configuration of the mobile communication terminal in the second embodiment is basically the same as that of the mobile communication terminal 1000 in the first embodiment. On the other hand, in the operation of the GPS communication unit 400, the second embodiment is different from the first embodiment.

  FIG. 6 shows an operation flow of the mobile communication terminal according to the second embodiment of the present invention. 6 and FIG. 5 are compared, S503 to S513 in FIG. 6 are the same as FIG. On the other hand, S601 and S602 in FIG. 6 are different from S501 and S502 in FIG. That is, in FIG. 5, the mobile communication terminal 1000 obtains the current terminal position information (latitude, longitude) after receiving the data communication start command (S501, S502), whereas in FIG.

<Third Embodiment>
Next, a mobile communication terminal according to a third embodiment of the present invention is described. The configuration of the mobile communication terminal in the third embodiment is basically the same as that of the mobile communication terminal 1000 in the first embodiment. On the other hand, in the operation of the information detection unit 540, the third embodiment is different from the first embodiment.

  FIG. 7 shows an operation flow of the mobile communication terminal according to the third embodiment of the present invention. 7 and FIG. 5 are compared, S501 to S513 in FIG. 7 are the same as FIG. On the other hand, in FIG. 7, both are different in that S701 is included between S503 and S504. In other words, in FIG. 5, after the process of S502, the information detection unit 540 displays the communication state information including the terminal position information indicating the position within a predetermined range (for example, within 10 m) from the same position as the current terminal position information. Is detected (S503, YES), the process of S504 was performed. On the other hand, in FIG. 7, after the process of S502, the information detection unit 540 includes communication state information including terminal position information indicating a position within a predetermined range (for example, within 10 m) from the same position as the current terminal position information. In addition to the case where it is detected that the data is stored in the storage unit 600 (S503, YES), the throughput value included in the communication status information detected in S503 is a predetermined throughput value (for example,...). Only in the following cases (S701, YES), the process of S504 is performed.

  Also, when the information detection unit 540 detects that communication state information including terminal position information within a predetermined range from the current location is not stored in the storage unit 600 (S503, NO), or the communication state information detected in S503 When the throughput value included in is not less than or equal to the predetermined throughput value (S701, NO), or includes a throughput value higher than the throughput value included in the communication state information detected in S504, and the same operation mode as the selected operation mode When it is determined that the communication state information including “NO” is not stored in the storage unit 600 (S504, NO), the mobile communication terminal 1000 sends the information stored in the storage unit 600 to the user. Without providing, a display prompting data communication is displayed in S509.

  As described above, in the mobile communication terminal according to the second embodiment of the present invention, the information detection unit 540 indicates a terminal that indicates a position within a predetermined range from the position indicated by the current terminal position information (the current location of the mobile communication terminal 1000). In addition to the case where it is detected that communication state information including position information is stored in the storage unit (S503, YES), the throughput value included in the detected communication state information is a predetermined throughput value. In the case of the following (S701, YES), the communication state information including a throughput value higher than the throughput value included in the detected communication state information and including the same operation mode as the selected operation mode is stored in the memory. It is determined whether it is stored in the section (S504).

  In this way, the processing after S504 is performed only when the throughput value within a predetermined range from the current location of the mobile communication terminal 1000 is lower than the predetermined value. On the other hand, when the throughput value within a predetermined range from the current location of the mobile communication terminal 1000 is sufficiently high, the processing of S509 to S513 is immediately performed without performing the processing of S504 to S508. Therefore, only when the throughput value around the current location of the mobile communication terminal 1000 is low, the user of the mobile communication terminal 1000 is suitable for the current location and operation mode of the mobile communication terminal 1000, such as a position where the throughput value is higher. Useful information can be provided efficiently.
