[First embodiment]
Hereinafter, a mobile communication terminal apparatus according to a first embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a mobile communication terminal apparatus according to the first embodiment of the present invention.

  In the figure, a radio signal transmitted from a base station (not shown) is received by an antenna 11 and then input to a receiving circuit (RX) 13 via an antenna duplexer (DUP) 12. The receiving circuit 13 mixes the received radio signal with the local oscillation signal output from the frequency synthesizer (SYN) 14 and converts the frequency into an intermediate frequency signal (down-conversion). Then, the receiving circuit 13 orthogonally demodulates the down-converted intermediate frequency signal and outputs a received baseband signal.

  The frequency of the local oscillation signal generated from the frequency synthesizer 14 is indicated by a control signal SYC output from the control unit 23.

  The received baseband signal is input to the CDMA signal processing unit 16. The CDMA signal processing unit 16 includes a RAKE receiver. In this RAKE receiver, a plurality of paths included in the received baseband signal are each subjected to despreading processing using spreading codes. Then, the signals of the respective paths subjected to the despreading process are synthesized after their phases are adjusted. Thus, received packet data in a predetermined transmission format is obtained. The received packet data is input to a compression / decompression processing unit (hereinafter referred to as a compander) 17.

  The compander 17 separates the received packet data output from the CDMA signal processing unit 16 for each medium by a demultiplexing unit. The compander 17 performs a decoding process on the data for each separated medium. For example, in the call mode, audio data such as call voice included in the received packet data is decoded by a speech codec.

  In addition, the mobile communication terminal apparatus according to the present embodiment has a so-called videophone function, but if the received packet data includes video data as in the videophone, the video data is decoded by a video codec.

  The digital audio signal obtained by the decoding process is supplied to a PCM code processing unit (hereinafter referred to as a PCM codec) 18. The PCM codec 18 performs PCM decoding on the digital audio signal output from the compander 17 and outputs an analog audio signal. The analog audio signal is amplified by the receiving amplifier 19 and then output from the speaker 20.

  When the audio playback mode is set, the control unit 23 reads out the corresponding audio content from the storage unit 24, decodes the audio content, and then decodes the audio content via the PCM codec 18 and the receiving amplifier 19. Amplify output from.

  The digital video signal decoded by the compander 17 is input to the control unit 23. The control unit 23 displays the digital video signal output from the compander 17 on the display 28 via the video RAM. Note that the control unit 23 displays not only the received video data but also video data captured by a camera 33 described later on the display 28 via the video RAM.

  The compander 17 supplies the e-mail to the control unit 23 when the received packet is an e-mail. The control unit 23 stores the electronic mail in the storage unit 24. Then, according to the operation state of the input device 27, the electronic mail is read from the storage unit 24 and displayed on the display 28.

  On the other hand, in the call mode, the voice signal of the speaker input to the microphone 21 is amplified to an appropriate level by the transmission amplifier 22 and then subjected to PCM encoding processing by the PCM codec 18 to become a digital audio signal, which is the compander. 17 is input. The video signal output from the camera 33 is digitized by the control unit 23 and input to the compander 17. Note that the electronic mail created in the control unit 23 is also input from the control unit 23 to the compander 17.

  The compander 17 detects the energy amount of the input voice from the digital audio signal output from the PCM codec 18, and determines the transmission data rate based on the detection result. The digital audio signal is encoded into a signal having a format corresponding to the transmission data rate, thereby generating audio data. In addition, the digital video signal output from the control unit 23 is encoded to generate video data. Then, these audio data and video data are packetized according to a predetermined transmission format by the demultiplexing unit, and this transmission packet data is output to the CDMA signal processing unit 16. Even when an electronic mail is output from the control unit 23, the electronic mail is multiplexed with the transmission packet data.

  The CDMA signal processing unit 16 performs spread spectrum processing on the transmission packet data output from the compander 17 using a spreading code assigned to a transmission channel. Then, the output signal is output to the transmission circuit (TX) 15. The transmission circuit 15 modulates the spread spectrum signal using a digital modulation method such as a QPSK (Quadrature Phase Shift Keying) method. The transmission signal generated by this modulation is combined with a local oscillation signal generated from the frequency synthesizer 14 and frequency-converted into a radio signal. Then, the radio signal is amplified at a high frequency so that the transmission power level indicated by the control unit 23 is obtained. The amplified radio signal is supplied to the antenna 11 via the antenna duplexer 12, and is transmitted from the antenna 11 to a base station (not shown).

  The power supply circuit 26 generates a predetermined operating power supply voltage Vcc based on the output of the battery 25 and supplies it to each circuit unit. The battery 25 is charged by the charging circuit 29.

  The GPS (Global Positioning System) information acquisition means 30 receives the current location information (GPS information; location information of the current location of the mobile communication terminal device) via the antenna 31 and inputs it to the control unit 23.

  Here, the control unit 23 includes, for example, a microcomputer (CPU; Central Processing Unit), and performs operation control characteristic of the mobile communication terminal device according to the first embodiment as described later.

  When the control unit 23 is viewed from the viewpoint of function, the control unit 23 is a path search process responsible for operation control of a path search process described later as a component that performs operation control peculiar to the first embodiment. A control unit 23-1, and a communication control unit 23-2 for performing communication control according to the processing result of the route search processing control unit 23-1.

  Here, a detailed configuration when the route search processing control unit 23-1 is viewed from a functional viewpoint will be described with reference to FIG. As shown in the figure, the route search processing control unit 23-1 includes a communication condition acquisition unit 23A, a communication line selection unit 23B, a destination information acquisition unit 23C, a route search unit 23D, and a communication schedule creation unit. 23E.

  The communication condition acquisition unit 23A acquires information (hereinafter referred to as communication condition information) related to the type of communication scheduled to be performed by the user. Specifically, for example, the following information is acquired by the communication condition acquisition unit 23A.

(A) Real-time communication (communication that needs to be performed continuously such as telephone, TV phone, chat, etc.) or non-real-time communication (communication that does not necessarily need to be performed continuously from the beginning to the end, such as data download) (B) Information on bit rate (for real-time communication) and data size (for non-real-time communication) (c) Minimum conditions required for communication line (line speed, line quality, delay rate, Here, specific information acquisition methods include input from the user, settings recorded in advance in the mobile communication terminal device, settings stored on the network, and the like. it can.

  The communication condition information acquired by the communication condition acquisition unit 23A as described above is sent to the communication line selection unit 23B and is used for efficient communication line selection.

  The destination information acquisition unit 23C acquires destination information, which is information indicating a destination, by input from a user or the like, and inputs the destination information to the communication line selection unit 23B.

  While the mobile communication terminal apparatus moves from the current location to the destination based on the various pieces of input information (the communication condition information, the destination information, and the communication line information described later), the communication line selection unit 23B Select the line information that can communicate efficiently with the communication requested by the user.

  By the way, the communication line information database 102 shown in FIGS. 1 and 2 is a database in which information about available communication lines (hereinafter referred to as communication line information) is stored. The communication line information stored in the communication line information database 102 is sent to the control unit 23 and used for line selection by the communication line selection unit 23B.

  Specific examples of the communication line information include information indicating the position of a base station or an access point, a communicable distance, a communicable position, a communication line speed, a communication line quality, a communication line congestion degree, and the like. it can.

  In the block diagram shown in FIG. 1, the communication line information database 102 is provided in the mobile communication terminal device, but it is needless to say that the configuration is not limited thereto. For example, there may be a server or a content provider that provides information corresponding to the communication line information on the network, and the information corresponding to the communication line information may be acquired from them.

  By the way, the destination information acquired by the destination information acquisition unit 23C and the communication line information selected by the communication line selection unit 23B are input to the route search unit 23D. The destination information and the communication line information are used for route search in the route search unit 23D.

  In other words, based on the destination information and the communication line information, the route search unit 23D searches for a route on which the mobile communication terminal apparatus can use the optimum line while moving from the current location to the destination. Then, route information (information indicating a route in which the mobile communication terminal device can use the optimum line while moving from the current location to the destination, an area where data communication is possible, etc.) is created. The route information is input from the route search unit 23D to the communication schedule creation unit 23E.

  Here, examples of the route search algorithm include the following algorithms. That is, for example, a plurality of candidate routes are output, and an available line and available time on the route are calculated, and it is determined whether or not necessary transmission time and transmission capacity can be secured. An algorithm such as selecting a route with the lowest communication cost from routes that match the conditions can be given.

  The communication schedule creation unit 23E creates communication schedule information, which is information indicating a communication schedule for performing communication control, based on the route information, and stores the communication schedule information in the communication schedule database 104. Here, the communication schedule database 104 shown in FIGS. 1 and 2 is a database for storing the communication schedule information.

  Specifically, the communication schedule creation unit 23E creates the communication schedule information by using information indicating “when”, “where from where to where”, and “which line is used” included in the route information. To do.

  Here, FIG. 3 is a diagram showing a simplified concept of information indicating “when”, “section from where to where”, and “which line is used” included in the route information. In the figure, the thick line indicates the scheduled communication section 51, and the broken line indicates the communication suspension section 53. That is, the mobile communication terminal apparatus performs communication processing such as data reception in the scheduled communication section 51 and does not perform communication processing in the communication suspension section 53.

  In the case of the route search algorithm as described above, for example, as shown in FIG. 4, the route B that is the shortest route is not simply selected, but is selected in consideration of the various communication conditions described above. Route A, which is the selected route, is selected.

  Hereinafter, with reference to flowcharts shown in FIG. 5 and FIG. 6, route search operation control by the control unit 23 of the mobile communication terminal device according to the first embodiment will be described.

  FIG. 5 is a flowchart showing a route search process by the control unit 23 of the mobile communication terminal device according to the first embodiment. FIG. 6 is a flowchart showing a subroutine of the conditional route search step in the flowchart shown in FIG.

  First, destination information is acquired by the destination information acquisition unit 23C, and a destination is set based on the destination information (step S1). Here, as a specific means for the destination information acquisition unit 23C to acquire the destination information, for example, a destination setting operation using the input device 27 or the like by the user can be mentioned.

  Subsequently, communication condition information (for example, information described in (a) to (c)) is acquired by the communication condition acquisition unit 23A, and various communication conditions are set based on the communication condition information (step) S2).

  Based on the destination set in step S1 and the communication conditions set in step S2, the route search unit 23D searches for an optimum route from the current location to the destination (creates route information) (step S3). ).

  Details of step S3 will now be described with reference to a subroutine shown in FIG.

  First, the current location information of the mobile communication terminal device is acquired by the GPS information acquisition means 30, and the shortest route to the destination set in step S1 is selected by the route search unit 23D (step S3- 1).

  In this step S3-1, in the current route search process, a route that has been excluded from the candidate route by the user in advance is not considered as a route search candidate, and the route with the shortest distance is selected from other candidate routes. Select.

  Subsequently, the communication path status in the shortest distance candidate path selected in step S3-1 (for example, contract information relating to data communication of the mobile communication terminal apparatus, the communication path corresponding to the mobile communication terminal apparatus is shown) Information, information indicating the communication path desired by the user, etc.) are acquired (step S3-2). In addition, as a specific acquisition method of the communication path condition in step S3-2, for example, a method of using a communication path condition stored locally in each mobile communication terminal apparatus, or access from the mobile communication terminal apparatus to the network Then, a method for acquiring the communication path status from a server or the like can be mentioned.

  Here, when the latter method is adopted, for example, contract information related to data communication of the mobile communication terminal device, information indicating a communication path corresponding to the mobile communication terminal device, information indicating a user desired communication path, and the like Can be transmitted to the server, and information related to the communication paths matching these can be returned from the server to the mobile communication terminal device. Of course, such a method can also be applied to a method of using a communication path condition locally stored in each mobile communication terminal device.

  If the conditions set as the communication path status do not change for each route search process, narrow down candidate paths according to the conditions stored locally or cached in each mobile communication terminal device in advance. Of course, it is possible to increase the speed and efficiency of the route search process.

  After acquiring the communication path status in step S3-2, based on the communication path status and the communication conditions set in step S2, the shortest path selected in step S3-1 is the desired data. It is calculated whether or not the communication path is possible (step S3-3).

  In step S3-3, for example, the following calculation is performed.

(1) In the case of non-real-time communication ・ Distance of communicable area ・ Movement speed of the mobile communication terminal device in the communicable area (calculated in consideration of various moving means such as walking, train, and car)
-Total amount of data that can be communicated (calculated using communication speed (average bit rate, etc.)).

(2) In the case of real-time communication ・ Whether data communication at the required communication speed is possible in all moving sections.

  When the calculation process in step S3-3 is completed, based on the calculation process result, the shortest path selected in step S3-1 is a path through which data communication required for the mobile communication terminal device is possible. It is determined whether or not there is (step S3-4).

  When step S3-4 is branched to NO, the process returns to step S3-1. On the other hand, when step S3-4 is branched to YES, the route search process is terminated and the process returns to the flowchart shown in FIG.

  For example, regarding data reception processing, even if data reception processing is performed using the entire communicable section, if there is no time to complete the requested data reception processing, the communication channel status Depending on the situation, the data reception process may not be completed. In such a case, information (process completion possibility information) indicating that “the data reception process may not be completed depending on the communication path status” may be added to the determination result in step S3-4. Good.

  When the route search process in step S3 ends, the route search process result is presented to the user as follows (step S4). That is, the route obtained by the route search in step S3 is presented by, for example, a method of highlighting on the map display on the display 28 (display method conventionally used), and an area where data communication is possible Points that can be communicated are also presented to the user by, for example, color-coded display on the map display.

  In step S4, the process completion possibility information may be further presented. The user can select whether to move along the presented route or search for another route again by referring to the presented processing completion possibility information.

  Furthermore, similarly in the case of real-time communication, for example, when a route that is an area in which only a small part of the section is not communicable and satisfies all other conditions is searched, that is the only case. Whether or not the route is selected by presenting that there is a part of the area where communication is not possible to the user in step S4. It may be determined whether to select the route according to the user's determination.

  Hereinafter, a detailed configuration of the control unit 23 when the communication control unit 23-2 is viewed from the viewpoint of function will be described with reference to FIG.

  As shown in FIG. 7, the communication control unit 23-2 includes a position information acquisition unit 23G, a line state monitoring unit 23H, a communication determination unit 23I, and a communication processing unit 23J.

  The location information acquisition unit 23G acquires current location information indicating location information of the current location of the mobile communication terminal device, for example, by the GPS information acquisition means 30.

  The line state monitoring unit 23H monitors a line that can be communicated at the time point, and acquires information (hereinafter referred to as line state information) indicating the line that can be communicated at the time point. Then, the line state monitoring unit 23H outputs the acquired line state information to the communication determination unit 23I.

  In addition to the line state information, the communication schedule information generated by the route search processing control unit 23-1 is also input from the communication schedule database 104 to the communication determination unit 23I.

  The communication determination unit 23I determines whether or not the mobile communication terminal apparatus exists at the position set by the communication schedule information, and determines whether or not the scheduled communication line can be used. When the communication terminal device is in a state that matches the planned condition, the communication instruction information is transmitted to the communication processing unit 23J.

  The communication processing unit 23J performs communication control according to the communication instruction information transmitted from the communication determination unit 23I.

  Hereinafter, the communication control processing by the control unit 23 in the mobile communication terminal apparatus according to the first embodiment will be described with reference to the flowchart shown in FIG.

  First, the communication determination unit 23I acquires the communication schedule information from the communication schedule database 104 (step S11). Subsequently, the communication determination unit 23I transmits the communication schedule information to the communication processing unit 23J. Then, specific communication scheduling is performed by the communication processing unit 23J based on the communication schedule information (step S12).

  In the communication scheduling in step S12, for example, the communication start position and the latitude / longitude information of the communication end / interruption place (further, height information may be included) are set as the position information. Thereby, when the said mobile communication terminal device is located in a communication start position, for example, the said communication process part 23J can be controlled to start communication.

  Note that not only the position information as described above but also an access point name or the like is set, so that the communication processing unit 23J starts communication when communication with the registered access point becomes possible. It is also possible to perform control.

  When the processing in step S12 is completed, the communication determination unit 23I refers to the current location information acquired from the location information acquisition unit 23G and the communication schedule information, and the mobile communication terminal device is located in the communication start area. Then, it is determined whether or not the communication line that has been scheduled can be used (step S13). When step S13 is branched to NO, the process returns to step S13 again.

  That is, step S13 is a step of waiting for the mobile communication terminal device to be located in the communication start area.

  When the mobile communication terminal apparatus is located at a location away from the communication start position, there is little possibility that the communication start condition is satisfied immediately. Therefore, in such cases, frequently acquiring and determining the current location information may place unnecessary load on the system, reduce the performance of other applications, and promote unnecessary battery consumption. End up.

  In view of such circumstances, based on the moving speed of the mobile communication terminal device, a time during which the process in step S13 can be set to sleep is calculated, and the process in step S13 is set to sleep based on the calculation result. You may let them.

  At this time, instead of simply calculating the sleep time, the sleep time may be set to a short time by a predetermined time in consideration of an increase in the moving speed of the mobile communication terminal device.

  Further, the closer the position of the mobile communication terminal device is to the communication start position, the more frequently the determination process in step S13 is performed, so that communication may be started with good response.

  By the way, the case where the step S13 is branched to YES is a case where the mobile communication terminal apparatus is in a state that matches the planned condition, and therefore the communication determination unit 23I transmits the communication instruction information to the communication process. The communication processing unit 23J performs communication control according to the communication instruction information (step S14).

  Thereafter, the communication determination unit 23I determines whether or not all requested communication processes have been completed (step S15). When step S15 is branched to NO, the process returns to step S13. On the other hand, when step S15 is branched to YES, the communication control process is terminated.

  The series of processes described above is automatically performed by the control unit 23. However, in practice, the process may be performed by the control unit 23 as needed based on the user's manual operation as follows. Good.

  That is, when the mobile communication terminal apparatus is located at the communication start position, the control unit 23 notifies the user of the fact by voice or vibration, and the control unit 23 performs communication control by a predetermined manual operation by the user who recognizes the fact. Of course, the processing may be started.

  In this case, since the communication control process can be started based on the final judgment by the user, the risk of malfunction can be reduced. In addition, the communication control process can be applied to a communication process involving the user himself such as a telephone call.

  Note that the following processing may be performed as an abnormal system response.

  For example, when the mobile communication terminal device is located at a position where data communication is scheduled, if the communication line scheduled to be used cannot be found or cannot be used, the communication determination unit 23I You may perform control of waiting for a fixed time until it becomes communicable using the communication line which is due to be used.

  Here, if communication using the communication line scheduled to be used is not possible after a certain period of time, the communication determination unit 23I performs control to stop the communication and informs the user to that effect. May be notified.

  Furthermore, in order to deal with such an abnormal system, it is of course possible to adopt a method of canceling the process without performing the process of waiting for a predetermined time. Furthermore, when the processing is canceled, the route search processing control unit 23-1 may perform the route search processing again to determine whether the user's desired communication can be performed. If it is determined that communication is possible, a new route may be presented to the user and the process may be continued.

  On the other hand, when it is determined that there is no route that can complete the desired communication as a result of the route search processing, the fact is presented to the user and the processing is terminated.

  For example, the following information may be displayed on the navigation map displayed on the display 28.

A point where the data communication process starts and a point where the data communication process ends. A path where the data communication process is performed and a path where the data communication process is not performed. A point where the data communication process is completed. Displaying such information on the display 28. Thus, the user can visually recognize the communication status and the like. Such a device can be applied to various types of guidance such as voice guidance.

  As described above, according to the first embodiment, it is possible to provide a mobile communication terminal device capable of performing efficient and high-quality communication when performing data communication while moving to a destination. Can do.

With such a configuration, the mobile communication terminal device according to the second embodiment acquires current location information from the car navigation device 74.

  The connection between the mobile communication terminal device and the car navigation device 74 may be made either by wire or wireless.

  As shown in FIG. 11, the route search processing control unit 23-1 includes a communication condition acquisition unit 23A, a communication line selection unit 23B, and a communication schedule creation unit 23E.

  The communication condition acquisition unit 23A acquires communication condition information that is information related to a communication condition and a communication environment that a user is requesting for communication, and inputs the communication condition information to the communication line selection unit 23B.

  Here, specific information acquisition methods by the communication condition acquisition unit 23A include user input using the input device 27, settings recorded in advance in the mobile communication terminal device, and storage on the network. The setting etc. which can be mentioned can be mentioned.

  The communication condition information collected by the communication condition acquisition unit 23A as described above is sent to the communication line selection unit 23B and used for efficient communication line selection. In addition, route selection result information is input to the communication line selection unit 23B from the car navigation device 74 via the interface 72. The route selection result information is information indicating a route that the mobile communication terminal device follows in the movement from the current location to the destination.

  While the mobile communication terminal device moves from the current location to the destination based on various input information (the communication condition information, the route selection result information, and communication line information described later), the communication line selection unit 23B In addition, line selection result information, which is information indicating a line that can be used for communication requested by the user and can be efficiently communicated, is created and input to the communication schedule creating unit 23E.

  By the way, the communication line information database 102 shown in FIG. 11 is a database in which information of available communication lines (communication line information) is stored. The communication line information stored in the communication line information database 102 is sent to the control unit 23 and used for line selection by the communication line selection unit 23B.

  Here, examples of the communication line information include information such as the position of a base station or an access point, a communicable distance, a communicable position, a communication line speed, a communication line quality, and a communication line congestion degree.

  In the block diagram shown in FIG. 11, the communication line information database 102 is configured in the mobile communication terminal device, but it is needless to say that the configuration is not limited thereto. For example, there may be a server or a content provider that provides information corresponding to communication line information on the network, and information corresponding to communication line information may be acquired from them.

  The communication schedule creation unit 23E creates communication schedule information, which is information indicating a communication schedule for performing communication control, based on the line selection result information, and stores the communication schedule information in the communication schedule database 104. Here, the communication schedule database 104 is a database for storing the communication schedule information.

  Hereinafter, with reference to the flowcharts shown in FIG. 12 and FIG. 13, route search operation control by the control unit 23 of the mobile communication terminal device according to the third embodiment will be described.

  First, route selection result information is acquired from the car navigation device 74 via the interface 72 by the communication line selection unit 23B (step S31). Subsequently, various communication conditions are set based on the communication condition information acquired by the communication condition acquisition unit 23A (step S32). Here, specific methods for acquiring the communication condition information by the communication condition acquisition unit 23A include an input by the user using the input device 27 and the like, settings recorded in advance in the mobile communication terminal device, The settings saved in can be listed.

  And the said communication line selection part 23B selects the area which communicates based on the communication conditions set in the said step S32 (step S33). Here, the details of step S33 will be described with reference to the subroutine shown in FIG.

  First, based on the communication condition information, communication line information, and route selection result information by the communication line selection unit 23B, information on communication points on the route (for example, access point, base station position, communication method, communication) Information indicating capacity and the like) is acquired (step S33-1).

  Subsequently, referring to the information regarding the communication point acquired in step S33-1, a communicable part suitable for the communication condition requested by the user is extracted (step S33-2). Specifically, in this step S33-2, for example, only the access points that can be used by the provider contracted by the user are extracted from the communication points searched in step S33-1. I do.

  Then, the most appropriate communication area for the communication condition requested by the user is selected from the communicable locations extracted in step S33-2 (step S33-3). In step S33-3, for example, when it is not necessary to perform communication using all of the communicable locations extracted in step S33-2, that is, out of the communicable locations extracted in step S33-2. If the requested communication process can be completed by using only a part, priority is set for the communication line based on the communication quality, communication speed, etc., and this priority is assigned to the higher communication line. elect.

  When setting the priority order for a communication line, if all communication processes can be completed at one communication point, the communication point used for the communication point is raised and the communication point is selected. By making it easy, it is possible to prevent complicated communication processing performed by switching a plurality of communication points. Conversely, when the requested communication process cannot be completed with only one communication point, communication using a plurality of communication points may be performed.

  When the communication location selection process in step S33 is completed, the communication location selection process result is presented to the user by the following means (step S34). Here, as specific means for presenting to the user, for example, the communication location obtained by the communication location selection process in step S33 may be displayed in a color-coded manner on the map display on the display 28, for example. I can do it.
