Description

  The present invention relates to a mobile communication device that relays transmission / reception of content data between a base station device and a terminal device in mobile communication by temporarily storing the content data.

In recent years, a station or a coffee shop is connected to a network such as the Internet via an access point (an example of a base station device) via wireless LAN communication at a branch office, a coffee shop, etc. ) To provide public wireless spot services that can be viewed, and to receive distribution of content such as music data by wireless or wired connection to an information kiosk (an example of a base station device) installed at a station, etc. Mobile communication environments such as providing content distribution services that can be used are being developed.
Conventionally, in order to use such a mobile communication environment, a terminal (terminal) such as a personal computer (personal computer) or PDA equipped with a communication interface (I / F) such as a wireless LAN card in a place where mobile communication is possible. Device) to connect to the nearest base station device (access point, information kiosk, etc.). Here, when a small portable terminal such as a PDA or a cellular phone is used as a terminal, there are many restrictions on data input, display size of content data, processing capability, and the like. For this reason, there are many cases where it is desired to use a relatively large terminal such as a notebook personal computer when creating outgoing mail (content) or using received content.
On the other hand, Patent Document 1 discloses a storage unit for information necessary for connecting a wireless LAN card to a wireless LAN communication network (setting information related to a network such as a communication protocol, and personal information such as a user ID and a password used for establishing communication). And a communication apparatus provided with a wireless communication CPU that automatically processes communication connection using the information. As a result, if a personal computer (external control device) equipped with the wireless LAN card is used, when connecting to the wireless LAN communication network, the user has to input the user ID, password, etc. from the personal computer every time the communication connection is made. Eliminates and enables simple network connection.
JP 2001-77878 A

However, since a terminal such as a personal computer cannot be used while walking, and it is not always possible to secure a use place such as a table where the terminal can be used in a place where communication with the base station apparatus is possible, There was inconvenience (problem) that we had to find a usable place.
Also, when a user wants to use (can use) a terminal, the base station device is often not located nearby, or radio waves do not reach in buildings where the terminal can be used on the road, and the user wants to use the terminal. There is also a problem that mismatches that cannot access the base station apparatus at a place where (can be) are likely to occur.
Furthermore, in order to start the communication connection to the base station device after securing the terminal usage location and starting the terminal, communication connection is established and content (e-mail, homepage, music data, etc.) is transmitted and received. During this time, there was a problem that the user had a waiting time and the time efficiency was poor.
The above problems cannot be solved even by using the technique disclosed in Patent Document 1.
Therefore, the present invention has been made in view of the above circumstances, and the object of the present invention is to relay transmission / reception of content data between a base station apparatus and a terminal apparatus in mobile communication, such as a personal computer. An object of the present invention is to provide a portable communication device that eliminates the inconvenience due to restrictions on the place where a terminal is used and reduces the waiting time of a user required for communication.

In order to achieve the above object, the present invention is a portable communication device that is configured to be portable and communicates with each of a predetermined base station device and a predetermined terminal device. A communication setting information storage unit that stores communication setting information related to communication with the terminal device, and a first wireless communication or a wired connection between the base station device based on the communication setting information. Between the communication means and the second communication means for performing communication by wireless or wired connection with the terminal device based on the communication setting information, and the base station device and / or the terminal device Data storage means for temporarily storing content data transmitted / received in the terminal, and when the communication by the second communication means is possible, the terminal device and the data storage means via the second communication means Content data is transmitted between the base station apparatus and the data storage means via the first communication means when the content data is transmitted and / or communication by the first communication means is possible The portable communication apparatus is characterized by comprising a control means for performing the processing and a power supply for supplying power to each means constituting the portable communication apparatus.
With the configuration as described above, the user of the terminal device obtains via the base station device at any place where the terminal device can be used (location or timing regardless of whether communication with the base station device is possible). Information regarding the acquisition destination of the content data desired to be transmitted and the transmission destination of the content data desired to be transmitted is set as the communication setting information, and the content desired to be transmitted to the portable communication device (the data storage unit) via the base station device If the data is transferred, the terminal device is used to acquire the desired content data (download to the data storage means) and transmit the content data while the portable communication device is being carried or moved. It becomes possible to do without.
As a result, the user can use (play, edit, etc.) the content temporarily stored in the portable communication device at any place where the terminal device can be used, and can communicate with the base station device. This eliminates the conventional inconvenience of having to find a place where the terminal device can be used in a particular place.
Furthermore, since the communication setting information is stored, it is not necessary to perform operations (connection destination designation, user ID / password input, etc.) necessary for establishing communication every time communication is performed, and the use place of the terminal device is secured. Thus, since the transmission / reception of the content data to / from the base station device has already been completed when the terminal device is activated, the conventional problem that a wasteful waiting time is generated for the user is solved.

Further, the first communication means is a wireless communication means, and the control means monitors the received electric field strength in the wireless communication means and determines whether or not communication is possible based on the received electric field strength. It is conceivable to perform control for automatically executing wireless communication based on the communication setting information when the mobile phone is in communication.
As a result, transmission / reception of content data to / from the base station apparatus is automatically executed only by the user carrying the portable communication apparatus and moving within the communication area of the base station apparatus.
Similarly, the second communication means is a wired communication means, and the control means monitors a connection resistance value of a communication line connected to the wired communication means and determines whether or not communication is possible based on the connection resistance value. Also, it is conceivable to perform control for automatically executing wired communication based on the communication setting information when it is determined that communication is possible.
Thereby, the trouble of performing an operation for starting communication from the terminal device can be saved.

In addition, since the portable communication device according to the present invention is carried by the device alone, convenience is impaired if the duration of the power source (battery) is short. For this reason, it is important to lengthen the duration of the power supply.
Therefore, when the second communication means is a wired communication means, and the wired communication means is connected to the terminal device via a communication line, the terminal device connects to the portable communication device via the communication line. If a power receiving means for receiving power supply is provided, the duration of the power source can be extended. Furthermore, it is still preferable if the power source is charged by the power received by the power receiving means.
Further, as a power saving measure, a clocking means for timing time, and a process related to power supply to the first communication means and communication by the first communication means in a predetermined time zone based on the timing result of the clocking means And a power supply control means for stopping the power supply.
As a result, if the communication by the first communication means is stopped in a time zone that does not normally move, such as at midnight, for example, power saving can be achieved, and the duration of the power supply can be extended.

Further, it is conceivable that the communication setting information storage means is a non-volatile memory, and the data storage means is a volatile memory whose memory is held by power supply from the power source.
In addition, the communication setting information storage means stores a relatively small amount of the communication setting information stored therein, and its access and update frequency is low, so that high speed is not required, but resetting takes time if lost. Therefore, it is preferable to use a non-volatile memory so that the memory is maintained even if the power supply is interrupted, although it is relatively slow.
On the other hand, since the data storage means stores content data that is frequently accessed and updated, and tends to have a large data capacity, it generally uses a volatile memory that can be read and written at high speed, and It is preferable that the memory is held by the power supply from.

In addition, if a base station communication result display means for displaying information related to a communication result with the base station apparatus is provided, it is easy to grasp the communication status.
Further, if the first communication means and / or the second communication means is a wireless communication means in the ISM band (2.4 GHz band: Industry Science Medical band), wireless communication can be performed without a license. Easy to use because it can.
The communication setting information may be set by providing an input means for the portable communication. However, in order to reduce the size and power consumption, the communication setting information is set to the first communication means. It is conceivable that the apparatus includes a setting information acquisition unit that is acquired from the terminal device via the communication terminal and stored in the communication setting information storage unit.

  According to the present invention, in transmission / reception of content data between a base station device and a terminal device in mobile communication, relaying is performed by temporarily storing (storing) content data, and communication with each of the base station device and the terminal device. By transmitting and receiving content data when possible, communication with the base station device is automatically performed while the user is carrying the mobile communication device and is moving. The inconvenience due to the restriction of the user is eliminated, and the waiting time of the user required for communication can be shortened (eliminated).

Hereinafter, embodiments and examples of the present invention will be described with reference to the accompanying drawings so that the present invention can be understood. It should be noted that the following embodiments and examples are examples embodying the present invention, and do not limit the technical scope of the present invention.
FIG. 1 is a block diagram showing a schematic configuration of the mobile communication device X according to the embodiment of the present invention, and FIG. 2 is a flowchart showing a procedure of communication control processing in the mobile communication device X according to the embodiment of the present invention. FIG. 3 is a block diagram showing a schematic configuration of the portable communication device X1 according to the embodiment of the present invention.

First, the configuration of the mobile communication device X according to the embodiment of the present invention will be described with reference to FIG.
The portable communication device X is a communication device configured to be portable, and is installed at an access point (public wireless spot) or a station in mobile communication, and distributes content data such as music data by wireless communication or wired communication. Communication is performed between the base station device 20 such as an information kiosk and the information terminal 30 (terminal device) such as a personal computer, and content data (e-mail, homepage) between the base station device and the information terminal. , Music data, etc.) are relayed by temporarily storing (storing) the content data.

  As shown in FIG. 1, the mobile communication device X includes communication setting information storage means 15 for storing communication setting information relating to communication with the base station device 20 (wireless base station) and communication with the information terminal 30; Wireless communication means (an example of the first communication means) for wirelessly communicating with the base station device 30 based on the communication setting information, and the information terminal such as a personal computer based on the communication setting information 30 (an example of the terminal device) is transmitted and received between the base station device 20 and the information terminal 30 and a wired communication unit (an example of the second communication unit) that communicates with the base station device 20 via the wired connection. Data storage means 16 for temporarily storing content data; control means 14 comprising a microcomputer and its peripheral devices (ROM, RAM, etc.) for performing various controls of the entire portable communication device X; Information on communication results between the power supply means 17 (power source), which is a battery (built-in battery) that supplies power to each means (each device) constituting the band communication device X, and the base station device 20 or the information terminal 30 And a user interface (I / O) having a slide switch, jog key, push button, etc. for performing various operation inputs (power on / off, manual communication start operation, etc.) to the portable communication device X. F) Means 13 are provided.

The wireless communication means 11 performs DSSS wireless LAN communication conforming to IEEE802.11b using radio waves in the ISM band (2.4 GHz band), and the intensity of radio waves received by an antenna (not shown) , Referred to as received electric field strength), and the detection result is output to the control means 14. In addition to the above, other wireless LAN communication methods include OFDM wireless LAN communication complying with IEEE802.11a and 11b, and FHSS wireless LAN communication complying with the Bluetooth communication method.
The wired communication means 12 conforms to a USB interface, a PCMCIA interface, or an interface such as a PCI bus, IEEE1394, RS232C, RS422, etc. provided in the information terminal 30 and is connected to the information terminal 30 via a predetermined communication line. When connected, it communicates with the information terminal 30 according to a predetermined communication protocol. Further, the wired communication unit 12 detects a connection resistance value of a communication line with the information terminal 30 and outputs the detection result to the control unit 14.
The communication setting information storage means 15 is composed of a nonvolatile memory such as a relatively small capacity flash ROM, and communication protocol type information (TCP / IP, necessary for establishing wireless LAN communication by the wireless communication means 11). UDP, PPP, HTTP, SMTP, POP3, IMAP, etc.), network setting information (IP address, default gateway, IP addresses of various servers, etc.), user information (user ID, password, etc.), access destination information (URL Etc.) is stored. Since the communication setting information storage means 15 has a relatively small amount of information stored in the communication setting information and its access and update frequency is low, high speed is not required. Although it is relatively slow, a non-volatile memory is used so that memory can be maintained even if power supply is interrupted.
The data storage means 16 is composed of a high-speed volatile memory such as a relatively large capacity SRAM, DRAM or SDRAM, and is continuously supplied with power from the power supply means 17 for several days to several weeks. During this time, data storage is maintained. As a result, it is possible to read / write content data that is frequently accessed and updated and that tends to have a large data capacity at high speed.
The control means 14 implements a Web server function by executing a predetermined program, and responds to an access from a Web browser (program) executed on the information terminal 30 by the Web server function. , Transmission and update of the communication setting information in the communication setting information storage means 15 (an example of the setting information acquisition means), storage of content data (such as transmission mail) in the data storage means 16, and the data storage means 16 content data (received mail, music data, etc.) is transmitted.
Further, the control means 14 is connected to a server on the Internet (the URL specified by the communication setting information is connected to the higher level side (core side) of the base station apparatus 20 via the wireless communication means 11. The set server) is accessed using a protocol such as HTTP, FTP, POP3, SMTP, etc., and contents data such as a home page, music data, and electronic mail (received mail) is acquired and stored in the data storage means 16. And further, a process of transmitting (transferring) content data (such as outgoing mail) acquired from the information terminal 30 and stored in the data storage means 16 to the server.

  The mobile communication device X is normally automatically communicated to the base station device 20 that can be carried by the user by itself (without being connected to the information terminal 30) by the user. A connection is established, content data is acquired (received), stored in the data storage means 16, and content data stored in the data storage means 16 is transmitted. Further, the user is connected to the information terminal 30 through a predetermined communication line, thereby establishing communication with the information terminal 30 and allowing the information terminal 30 to access the data storage means 16.

Next, the procedure of the communication control process controlled by the control means 14 will be described using the flowchart of FIG. Hereinafter, S11, S12,... Represent processing procedure (step) numbers.
When the portable communication device X is turned on, the wireless communication means 11 detects (measures) the received electric field strength (S11), and the control means 14 sets the received electric field strength to a predetermined set strength (threshold value). It is determined (threshold value determination) whether or not it is greater than (value) (S12).
Here, when the received electric field strength is less than the set strength, it is determined that communication with the base station apparatus 20 is impossible, and the process returns to S11 and is repeated.
On the other hand, when it is determined that the received electric field strength is equal to or higher than the set strength, communication with the base station device 20 is possible. A process (communication setting process) for establishing communication with the base station apparatus 20 is automatically executed (S13).
Next, when electronic mail data (transmission mail) is stored in a predetermined transmission folder of the data storage means 16, the electronic mail data is controlled by controlling the wireless communication means 11 and using SMTP. (Content) is transmitted to a predetermined outgoing mail server (server specified by the communication setting information) on the Internet on the upper side of the base station apparatus 20 (S14). At this time, the content data for which transmission to the base station apparatus 20 has been completed (transmitted) is deleted from the data storage means 16.
Next, by controlling the wireless communication means 11 and using POP3 or IMAP, a predetermined received mail server on the Internet (the server specified by the communication setting information) is accessed, and the received mail has arrived. In this case, the electronic mail data (content) is received and stored in the received mail folder of the data storage means 16 (S15).
Furthermore, by controlling the wireless communication means 11 and using HTTP, FTP, etc., specified by the communication setting information from a predetermined server on the Internet or from the information kiosk when the communication partner is the information kiosk The received contents such as the home page and music data are received and stored in a predetermined reception folder of the data storage means 16 (S16).
Finally, after the control means 14 displays the information of the communication results in S14 to S16 on the user I / F 13 (S17), the process returns to S11 and the above-described processing is repeated at a predetermined cycle.
Here, the display on the user I / F 13 (an example of the base station communication result display unit) blinks a predetermined LED when, for example, the received mail is acquired and stored in the data storage unit 16. Or when the transmission of content data such as a transmission mail is normally performed, the LED that has been turned on (indicating that there is a transmission mail) is turned off.
In addition, when there is a predetermined manual execution operation input from the user I / F means 13, the control means 14 executes the processes of S 13 to S 17 in response thereto.

In parallel with the processing of S11 to S17 (communication control with the base station apparatus 20) (in multitasking), the following communication control with the information terminal 30 is also executed.
First, the wired communication means 12 detects (measures) the connection resistance value of the communication line with the information terminal 30 (S21), and the control means 14 sets the connection resistance value to a predetermined set resistance value (threshold value). It is determined (threshold value determination) whether or not it is less than (value) (S22).
Here, if the connection resistance value is equal to or greater than the set resistance value, it is determined that communication with the information terminal 30 is impossible (no communication line is connected), and the process returns to S21 and is repeated.
On the other hand, when it is determined that the connection resistance value is less than the set resistance value, communication with the information terminal 30 is possible, so that the wired communication means 12 is controlled to control the connection based on the communication setting information. Communication access (data read / write) to the data storage unit 16 is permitted to the information terminal 30 (reading of data in the data storage unit 16 and the information of the data in response to a command from the information terminal 30) A process (communication setting process) for transmitting to the terminal 30 and receiving data from the information terminal 30 and writing the data to the data storage means 16 is automatically executed (S23).
Furthermore, by receiving access from the information terminal 30, content data (sent mail, etc.) received from the information terminal 30 is stored (written) in the data storage unit 16, and content in the data storage unit 16 is stored. Reading of data (received mail or the like) and transmission to the information terminal 30 are executed (S24). At this time, the content data transferred (transmitted) to the information terminal 30 is erased from the data storage means 16 in response to a command from the information terminal 30 or automatically after the transfer. At this time, when an update operation (setting input operation) of the communication setting information is performed in the information terminal 30, data update processing in the communication setting information storage unit 15 is also performed.
Then, after the control means 14 displays the information of the communication result in S24 on the user I / F 13 (S25), the process returns to S21 and the above-described processing is repeated at a predetermined cycle.
Here, the display to the user I / F 13 is, for example, when a transmitted mail is acquired and stored in the data storage means 16, a predetermined LED is turned on, or content data such as a received mail is normal. For example, the LED that was blinking (indicating that there is a received mail) is turned off when it is transferred (transmitted) to the information terminal 30.
Further, when there is a predetermined manual execution operation input from the user I / F means 13, the control means 14 executes the processes of S23 to S25 in response thereto.

Through the communication control as described above, when the communication by the wired communication unit 12 is possible, the content data transmission process is performed between the information terminal 30 and the data storage unit 16 via the wired communication unit 12. In addition, when communication by the wireless communication unit 11 is possible, content data transmission processing is performed between the base station apparatus 20 and the data storage unit 16 via the wireless communication unit 11.
As a result, the user of the information terminal 30 connects the information terminal 30 and the portable communication device X at an arbitrary place where the information terminal 30 can be used, and uses the base station device 20 as the communication setting information in advance. If the information regarding the acquisition destination of the content data desired to be acquired is set, and the content data desired to be transmitted via the base station device 20 is transferred to the portable communication device X (the data storage means 16 thereof) While carrying the communication device X, acquisition of desired content data (downloading to the data storage means 16) and transmission of the created content data are automatically performed. Therefore, the conventional inconvenience of having to search for a use place such as a table where the information terminal 30 can be used in a place where communication with the base station apparatus 20 is possible is solved.
In addition, when the user wants to use (can use) the information terminal 30, the base station device 20 is not present nearby, or the radio wave does not reach in a building where the information terminal 30 can be used at the destination. However, if the base station device 20 exists near the movement path along with the portable communication device X, content data is automatically transmitted and received, so that the user wants to use the information terminal 30. Thus, the conventional mismatch problem that the base station apparatus 20 cannot be accessed is solved.
Furthermore, when the information terminal 30 is secured and the information terminal 30 is activated, transmission / reception of content data to / from the base station device 20 has already been completed. This eliminates the conventional problem that occurs.

Next, a mobile communication device X1 that is an embodiment in which a configuration for power saving is added to the mobile communication device X will be described with reference to FIG.
Since the portable communication device (X, X1) according to the present invention is carried alone, the convenience is impaired if the duration of the power supply means 17 (battery) is short. For this reason, it is important to lengthen the duration of the power supply means 17.
The mobile communication device X1 is obtained by adding the following two elements to the mobile communication device X, and has the same configuration and function as the mobile communication device X except for the following.
One of the additional elements is that when the information terminal 30 is connected to the wired communication means 12, the portable communication device X1 receives power from the information terminal 30 (external) via the communication line. This is a power conversion circuit 18 (an example of the power receiving means) that supplies power to each of the means constituting the circuit. Further, the power conversion circuit 18 is connected to the power supply means 17 (battery), and is configured to charge the power supply means 17 with the received power from the information terminal 30.
Thereby, the duration of the power supply means 17 can be lengthened.
Furthermore, the second additional element is to measure the time using a real-time clock or the like, and when it is a predetermined time zone (hereinafter referred to as a stop time zone) set in advance, a signal indicating that the stop time zone is present. Time output means 19 for outputting. An output signal (time measurement result) of the time output means 19 is input to a switch (not shown) provided on the power supply path to the wireless communication means 11 and the control means 14 to indicate that it is the stop time zone. Is output to the wireless communication means 11 (including the received electric field strength detection unit) by the switch and processing related to communication by the control means 14 (S11 to S11 in FIG. 2). S17) is stopped (skipped). Here, the setting of the stop time zone is, for example, in response to a request from the Web browser of the information terminal 30 by the Web server function of the control means 14 when connected to the information terminal 30. It is conceivable to return a time zone setting page, acquire the time information set on the stop time zone setting page, and set it in the time output means 19. Of course, the user I / F means 13 may be used for input.
Thereby, if a time zone (for example, midnight) in which the user does not move with the portable communication device X1 is set as the stop time zone, useless power consumption can be suppressed, and the power supply means 17 The duration can be increased.

In the portable communication device (X, X1) described above, the communication means with the base station device 20 is a wireless communication device, but the present invention is not limited to this. For example, the base station device 20 has a USB interface. If it is an information kiosk or the like provided, it is also possible to use a wired communication means (USB interface) corresponding thereto. In this case, for example, it may be considered that the wired communication unit 12 is also used as a communication unit with the base station apparatus 20 and the user I / F unit 13 can switch which one to communicate with. It is done.
Similarly, in the portable communication device (X, X1), the communication means with the information terminal 30 is a wired communication means. For example, the information terminal 20 includes a wireless communication interface such as a wireless LAN or Bluetooth. If there is, a wireless communication means corresponding to this can be considered. Also in this case, for example, the wireless communication unit 12 may be used also as a communication unit with the information terminal 30 and the user I / F unit 13 may be configured to be able to switch which one is the communication partner. It is done.
In the portable communication device (X, X1), the wireless communication means 12 is a wireless communication means in the ISM band, but is not limited to this, for example, radio wave communication in other frequency bands such as a 5 GHz band. And those that perform optical communication are also conceivable.
Further, the communication setting information storage means 15 and the data storage means 16 may be constituted by a single storage means such as a flash memory.
