Description

  The present invention relates to a mobile communication terminal device that performs communication by autonomously establishing a wireless connection with a short-distance external information device.

  In the following Patent Document 1, when an in-vehicle device mounted on an automobile detects that a user has boarded by operating an engine key, opening / closing a door, seat weight sensor, etc., an inquiry communication is started with respect to a mobile phone. A connection establishment procedure in which a mobile phone responds to an inquiry communication has been proposed. That is, in this conventional example, it is assumed that the mobile phone is in a state of accepting inquiry communication from the vehicle-mounted device.

JP 2001-218262 A

  However, in actual mobile phone implementations, the inquiry communication is normally set not to be accepted for reasons such as power saving and security measures (it is easy to receive a security attack when the communication is accepted). Therefore, in order to communicate with the vehicle-mounted device, it is necessary for the user to perform a menu operation on the mobile phone and to switch to a mode that can explicitly accept inquiry communication. Therefore, the conventional method has a problem that it is difficult to apply to a mobile phone having a general mechanism.

  Furthermore, when inquiry communication is performed from the vehicle-mounted device side as in the conventional method described above, unnecessary inquiry communication is performed not only to the user but also to the surrounding mobile phone, which is inefficient. It was.

  The present invention has been made in view of the above, and an object of the present invention is to obtain a mobile communication terminal device, a wireless connection method, and a communication system that can autonomously establish a wireless connection with an external information device. .

  In order to solve the above-described problems and achieve the object, the present invention is a mobile communication terminal device that establishes a wireless connection with a short-distance external information device and performs communication, and obtains information from a sensor. Based on the location determination means for determining whether or not it exists in a preset specific location, and when the location determination means determines that the location exists in the specific location, the external communication device Communication control means for requesting a wireless connection to the wireless communication device, and after establishing the wireless connection under the control of the communication control means, performing an operation in cooperation with the external communication device via the connected communication path, Features.

  According to the present invention, it is possible to maintain the power saving state of the mobile communication terminal device during normal times and to significantly reduce the possibility of receiving a security attack.

  Embodiments of a mobile communication terminal apparatus according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration example of a mobile phone that operates as an example of a mobile communication terminal device according to the present invention. The mobile phone 1 in FIG. 1 includes a sensor unit 2, a place determination unit 3, a communication control unit 4, a communication unit 5, and a device cooperation unit 6. The sensor unit 2 includes, for example, a position sensor 2a that detects a current position (latitude and longitude), an acceleration sensor 2b that detects a moving speed, a vibration sensor 2c that detects vibration, and an ambient sound sensor 2d that collects ambient sounds. Are collected and processed to generate information that can be processed by the location determination unit 3, such as position information, acceleration information, vibration information, ambient sound information, and the like. To do.

  The location determination unit 3 holds a location determination condition for determining that it exists in a specific location, and based on the information notified from the sensor unit 2, the mobile phone 1 (or its user) periodically exists. Determine where to go. When it is determined that the mobile phone 1 exists in a specific place, the communication control unit 4 uses the communication unit 5 to execute a predetermined procedure for establishing a wireless connection with a short-distance external information device To do. The device cooperation unit 6 exchanges information necessary for device cooperation with the external information device via the connected communication path in a state where the wireless connection is established. Here, the place is not limited to a pure position, and includes a facility having a predetermined characteristic. In addition, the short distance generally means that the reach distance is about 100 meters or less.

  Moreover, in FIG. 1, the onboard equipment 10 is described as an example of an external information device. The vehicle-mounted device 10 is a device such as a car navigation system or a car audio device mounted on a car, and can be connected to the mobile phone 1 via radio. In the present embodiment, the place determination unit 3 includes a boarding condition for determining as “boarding a private vehicle” as the place determination condition.

  Here, the operation in the case where the mobile phone 1 configured as described above autonomously determines its own location will be described.

  FIG. 2 is a flowchart for the location determination unit 3 of the mobile phone 1 to determine whether or not the user of the mobile phone 1 is in a car. The place determination unit 3 executes the flowchart of FIG. 2 as needed based on information notified from the sensor 2 to determine the above boarding conditions. Here, it is assumed that the user carries the mobile phone 1 and gets on the automobile, and the flowchart of FIG. 2 is executed after the automobile starts running.

  First, the location determination unit 3 of the mobile phone 1 determines whether or not the moving speed exceeds a predetermined value based on the acceleration information, and if it is determined that the vehicle is running (step S1: Yes), next. Based on the position information, it is determined whether or not the automobile is present on the road. When traveling on the road (step S2: Yes), the place determination unit 3 next determines whether or not the ambient sound is a car-specific sound based on the ambient sound information. If it is determined that the vehicle is on board (step S3: Yes), the place determination unit 3 next determines whether the vibration pattern matches a prestored vibration pattern based on the vibration information. To do. And when it is judged that it is a vibration pattern peculiar to a user (Step S4: Yes), place judgment part 3 judges that it is "boarding a private car" at this stage (Step S5). The “previously stored vibration pattern” is a vibration pattern specific to the user (private vehicle) stored in the mobile phone 1 and is acquired in advance from, for example, an in-vehicle device. The mobile phone 1 may be provided with a function for recording a vibration pattern. In this case, the vibration pattern is acquired in advance from the function.

  On the other hand, when not traveling (Step S1: No), when not traveling on a road (Step S2: No), when not riding in a car (Step S3: No), vibration of a private car When it is determined that the pattern is not a pattern (step S4: No), the place determination unit 3 determines that “the vehicle is not in a private car” (step S6).

  The reason for providing these four conditions is to deal with various cases where it is not necessary to wirelessly connect to the vehicle-mounted device 10 even when riding in a car. For example, the condition of step S1 is to exclude the case of riding a bicycle. Further, the condition of step S2 is to exclude the case where the user gets on a vehicle (for example, a train) other than the automobile moving at a predetermined speed. The condition of step S3 is to exclude the case where the user gets on an automobile (for example, a public bus) not equipped with the vehicle-mounted device 10 to which the mobile phone is connected. The condition of step S4 is for excluding cases where the passenger rides in a taxi or a friend's car as a passenger. As described above, by using a plurality of conditions, the wireless connection is automatically performed only when the automobile that the user drives is routinely driven.

  Next, an operation when the mobile phone 1 configured as described above establishes a wireless connection with the vehicle-mounted device 10 will be described. FIG. 3 is a sequence diagram (part 1) illustrating a procedure for establishing a wireless connection.

  For example, when the location determination unit 3 of the mobile phone 1 determines that “the user is in a private car” and notifies the communication control unit 4 to that effect, the communication control unit 4 uses the communication unit 5. Control for establishing a wireless connection between the mobile phone 1 and the vehicle-mounted device 10 is performed. First, the communication control unit 4 generates an “activation request” for requesting the start of connection, and transmits the “activation request” to the vehicle-mounted device 10 via the communication unit 5 (step S10). If the in-vehicle device 10 is in a connectable state, the on-vehicle device 10 returns “start-up acceptance” to which the address (identifier for distinguishing from other communication devices) of the on-vehicle device 10 necessary for communication is added (step S11).

  Next, the communication control unit 4 that has received the “startup acceptance” transmits an “authentication request” via the communication unit 5 in order to exchange information necessary for authentication (step S12). ”Receives“ authentication information ”(step S13). And the communication control part 4 which received "authentication information" transmits "authentication confirmation notification" (step S14). As a result, the vehicle-mounted device 10 can recognize that it has been authenticated by the mobile phone 1.

  Thereafter, when the communication control unit 4 transmits a “connection request” via the communication unit 5 (step S15), the vehicle-mounted device 10 adds information such as a communication speed and a coding / decoding method necessary for subsequent communication. A “connection acceptance” is returned (step S16).

  When all the above steps are executed, a wireless communication path is established between the mobile phone 1 and the vehicle-mounted device 10, so the device cooperation unit 6 of the mobile phone 1 uses the vehicle-mounted device 10 using this communication path. Can be linked with the device. For example, (1) the telephone number stored in the phone book of the mobile phone 1 is transferred to the vehicle-mounted device 10, and the mobile phone 1 is operated during operation using the hands-free phone function of the vehicle-mounted device 10. (2) Transfer the music data stored in the mobile phone 1 to the vehicle-mounted device 10 and listen to the music with the audio device of the car. (3) Part of the map data of the vehicle-mounted device 10 The contents such as transferring to the mobile phone 1 and displaying the map information can be considered.

  Here, in the operation when establishing a wireless connection between the mobile phone 1 and the vehicle-mounted device 10, the operation when the vehicle-mounted device 10 refuses to accept activation will be further described. FIG. 4 is a sequence diagram (part 2) illustrating a procedure for establishing a wireless connection.

  In the sequence in FIG. 3, the vehicle-mounted device 10 that has received the “start-up request” has returned “start-up acceptance” (step S11), but in the sequence of FIG. 4, the on-vehicle device 10 returns “start-up acceptance denied”. (Step S20). This is a mode in which it is assumed that the vehicle-mounted device 10 itself sends a “startup request” and is a case that is not in a mode for accepting a “startup request”. In this case, the communication control unit 4 of the mobile phone 1 performs a control to transmit a “role change request” to the vehicle-mounted device 10, thereby requesting a shift to a mode for accepting a “start request” (step S <b> 21). . The vehicle-mounted device 10 that has received the “role change request” transmits “role change acceptance” to the mobile phone 1 after shifting to the mode for accepting “start request” (step S22). Subsequent processing is the same as the operation in steps S10 to S16 described above.

  As described above, in the present embodiment, the mobile phone autonomously determines that it is in a situation where wireless connection should be made based on information from various sensors, and at that time, wireless connection is made to the vehicle-mounted device. It was decided to request. Thereby, it is possible to maintain the power saving state of the mobile phone at the normal time. In addition, since activation is requested from the mobile phone side when necessary, that is, there is no need to wait for inquiries from the in-vehicle device while the communication is always accepted, so the possibility of receiving a security attack can be significantly reduced. Become.

Embodiment 2. FIG.
In the first embodiment, an on-vehicle device is taken as an example of the external information device, and a case has been described in which the mobile phone autonomously determines that wireless connection has been established and requests connection from the on-vehicle device. In the present embodiment, a case where an information device installed in a specific facility is assumed as the external information device will be described.

  FIG. 5 is a diagram showing a configuration example of a mobile phone that operates as an example of the mobile communication terminal device according to the present invention. The mobile phone 1B of FIG. 5 differs from the mobile phone 1 of FIG. 1 in that it includes a location determination unit 3B instead of the location determination unit 3, and further includes a reader 7 that reads information from an IC chip. . In addition, an information device 10B is assumed instead of the vehicle-mounted device 10 as a partner with which the mobile phone 1B communicates. The information device 10B is an external information device installed in a specific facility.

  In the present embodiment, the place determination unit 3B newly holds a place determination condition for determining that it exists in a specific place. For example, in order to determine “being in the station premises”, it is possible to set a condition that (1) the reader is notified that the ticket gate is bid, and (2) the vibration is equal to or less than a predetermined threshold. . Further, in order to determine “being on the platform”, it is possible to set a condition that (1) the reader is notified that the ticket gate has been bid, and (2) the ambient sound is a specific sound. In addition, in order to determine “on the train”, it is possible to set a condition that (1) the reader is notified that the ticket gate has been bid, and (2) the vibration is equal to or greater than a predetermined threshold. is there. In addition, in order to determine “being in the museum”, it is possible to set a condition that the reader has notified the fact. The place determination unit 3B determines the place where the mobile phone 1B exists based on these conditions.

  Various examples of device cooperation in these facilities and places can be assumed. For example, when it is notified that the ticket gate has been bid, it is possible to communicate with the station operation display device, and display the guidance of the platform for each train, the operation status, and the like on the display unit of the mobile phone 1B. In addition, the museum can communicate with installed information devices and display detailed information about the exhibits on the mobile phone 1B in front of each exhibit. On the train, you can automatically connect to wireless headphones and play music.

  As described above, in the present embodiment, conditions for autonomously determining the presence in a specific facility or place are stored, and not limited to the vehicle-mounted device, but wirelessly connected to installed information devices. It was decided to establish. Thereby, in addition to the same effects as those of the first embodiment, information useful in the place and situation can be used by using the mobile phone in every scene of life.

  In the above embodiment, an example in which a plurality of pieces of information from sensors and readers are used has been described. However, any one of information such as movement speed, acceleration, vibration, ambient sound, and position and information read by the reader is used. It may be used.

  As described above, the mobile communication terminal device according to the present invention is useful as a communication device such as a mobile phone, and is particularly suitable for communication by establishing a wireless connection with a short-distance external information device. ing.
