The present invention relates to a wireless communication terminal having a wireless communication function such as WLAN (Wireless LAN), and a method for controlling the wireless communication terminal.

In recent years, wireless communication terminals having wireless communication functions such as WLAN, infrared communication, and Bluetooth (registered trademark) have become widespread. For example, what is called a smartphone in which a mobile phone and a PDA (Personal Digital Assistant) are integrated, and what is called a smart pad larger than a smartphone correspond to this.

Smartphones and smart pads have a wide variety of functions such as a schedule function and a personal information management function, and the mobile phone function of the smartphone mainly supports wireless communication complying with the cellular wireless communication system. In addition, some smartphones operate as routers (hereinafter referred to as “3G routers”) that support wireless communication compliant with the cellular wireless communication method.

When connecting to the Internet using a smart pad, a method of connecting to an access point (hereinafter referred to as a “first access point”) using a WLAN and a smartphone having a 3G router as a second access point are used as a second access point. There is a way. Since the first access point is connected to the Internet by wire, when connecting to the first access point, the smart pad can connect to the Internet because the WLAN radio of the first access point reaches the smart pad. Limited to areas. When the smart pad goes out of the communication range that can be connected to the first access point, it is possible to continuously connect to the Internet by connecting the smartphone having the 3G router as the second access point. As described above, when connection using the first access point becomes impossible, connection using the smartphone having the 3G router as the second access point is performed. When it is possible to connect to the first access point during the connection with the second access point (that is, when the smart pad enters the communication range of the first access point by WLAN), the user of the smart pad is willing. To re-establish the connection with the access point.

As an invention in which the communication form is changed according to such a change in connection environment, there are inventions disclosed in Patent Document 1 and Patent Document 2, for example. In the invention disclosed in Patent Document 1 (name of invention: image transmission system), when communication between the image processing device and the relay communication device cannot maintain the wireless communication in the infrastructure mode, the mode is switched to the ad hoc mode. When communication is continued and access point communication is resumed, the communication mode is returned to the infrastructure mode to resume communication. According to the present invention, communication can be continued even when communication with the access point is disconnected. In the invention disclosed in Patent Document 2 (name of invention: device, wireless LAN setting system and wireless LAN setting method), a device and a PC (personal computer) are connected in an ad hoc mode, and WLAN setting parameters are transmitted from the PC to the device. And the device connects to the access point using the parameter. According to the present invention, the WLAN setting of the device can be easily performed.

Therefore, even after setting the connection to the second access point, if there is an environment in which the connection to the first access point is possible, the connection with the first access point is re-established without the user of the wireless communication terminal being aware of it. can do.

In the above configuration, the control unit performs connection setting processing with the second access point to create a profile of the second access point, and then sets the profile of the second access point to the first access point. Lower the priority than the profile of the first access point, store the connection with the second access point, disconnect according to the stored priority profile of the first access point and the profile of the second access point, Reconnect to the first access point.

According to the above configuration, by storing the profile of the second access point with a lower priority than the profile of the first access point, it is possible to reconnect with the first access point with priority. In other words, when both the first access point and the second access point have been scanned, if both can be confirmed, reconnection will be performed using a high priority profile. If the priority of the profile of the first access point is lower than the priority of the profile of the second access point, the connection with the second access point is prioritized and the connection with the first access point may be reconnected. Can not. Therefore, by lowering the priority of the profile of the second access point over the profile of the first access point, if the environment can be reconnected to the first access point, You will be able to reconnect.

In the above configuration, the second access point is compliant with another wireless communication method different from the predetermined wireless communication method.

In the above configuration, the predetermined wireless communication method is WLAN, and the other wireless communication method is cellular.

In the above configuration, the second access point is a mobile terminal having an access point function.

A method for controlling a wireless communication terminal according to the present invention is a method for controlling a wireless communication terminal including a wireless communication unit that is compliant with a predetermined wireless communication method and is connectable to a first access point and a second access point.

According to the above method, when receiving a connection start instruction with the second access point during the connection with the first access point, the wireless communication terminal disconnects the connection with the first access point, and then Connection with the second access point is started. After starting the connection with the second access point, the connection is set, and then the profile of the second access point is created. After creating the profile of the second access point, the connection with the second access point is disconnected, and then the connection with the first access point is made again. Therefore, even after setting the connection to the second access point, if there is an environment in which the connection to the first access point is possible, the user of the wireless communication terminal re-establishes the connection with the first access point can do.

In the above method, after the step of performing connection setting processing with the second access point to create a profile of the second access point, the profile of the second access point is changed from the profile of the first access point. According to the priority stored in the profile of the first access point and the profile of the second access point, the step of storing at a lower priority, the step of disconnecting the connection with the second access point, and the stored profile of the first access point and the profile of the second access point And reconnecting to the first access point.

According to the above method, by storing the profile of the second access point with a lower priority than the profile of the first access point, it is possible to reconnect with the first access point with priority. That is, when both the first access point and the second access point are scanned, if both can be confirmed, reconnection is performed using a profile having a high priority. If the priority of the profile of the access point is lower than the priority of the profile of the second access point, the connection with the second access point is prioritized and reconnection with the first access point is not possible. Therefore, by lowering the priority of the profile of the second access point over the profile of the first access point, if the environment can be reconnected to the first access point, You will be able to reconnect.

According to the present invention, even after setting the connection to the second access point, if there is an environment in which the connection to the first access point is possible, the user of the wireless communication terminal is not aware of the connection with the first access point.

Hereinafter, preferred embodiments for carrying out the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a wireless communication system using a wireless communication terminal according to an embodiment of the present invention. In the figure, the wireless communication terminal 1 of the present embodiment is a mobile terminal called a smart pad, and is a wireless LAN (hereinafter referred to as WLAN) (generally also referred to as WiFi (Wireless Fidelity)), A wireless communication unit capable of bidirectional communication with a plurality of wireless communication methods such as Bluetooth (registered trademark, hereinafter referred to as BT) and infrared communication is provided. The wireless communication terminal 1 uses, for example, TCP / IP (Transmission Control Protocol / Internet Protocol) and HTTP (Hyper に Text Transfer Protocol) as protocols necessary for data exchange using the Internet 100, and uses TCP / IP. Then, a communication path is established and data is transmitted and received using HTTP.

The wireless communication terminal 1 uses the protocol to connect to an access point (corresponding to a “first access point”, hereinafter referred to as “first access point”) 101 and connect to a Web server on the Internet 100 (illustrated). To a web server (not shown) on the Internet 100 via 3G by connecting to a smartphone (corresponding to a “second access point”, hereinafter referred to as “second access point”) 102. And can be accessed. Communication between each of the first access point 101 and the second access point 102 is performed by WLAN.

The second access point 102 is a portable terminal that can perform wireless communication conforming to the cellular wireless communication system and can also perform wireless communication such as the above-described WLAN, BT, and infrared communication. The second access point 102 also operates as a router (referred to as “3G router”) and can be connected to the Internet 100 via the 3G base station 103. The wireless communication terminal 1 can connect to the Internet 100 using the 3G router function of the second access point 102.

The connection to the Internet 100 by the first access point 101 of the wireless communication terminal 1 is possible only within the communication area of the first access point 101, and of course the first access when going out of the communication area. Connection to the Internet 100 by the point 101 is impossible. Even when the wireless communication terminal 1 goes out of the communication area of the first access point 101, it is possible to connect to the Internet 100 by using the second access point 102 as a 3G router. The wireless communication terminal 1 uses the second access point 102 so that the second access point 102 can be used to connect to the Internet 100 when the first access point 101 becomes unable to connect to the Internet 100. Has a function for setting connection. Hereinafter, the wireless communication terminal 1 will be described in detail.

FIG. 2 is a block diagram showing a schematic configuration of the wireless communication terminal 1. In the figure, a wireless communication terminal 1 includes a control unit 10 that controls each unit of the wireless communication terminal 1, an input unit 11 such as operation keys, a display unit 12 including a liquid crystal display and a touch panel, and bidirectional communication using a WLAN.

Prepare. The control unit 10 stores a program for controlling the units 11 to 14.

FIGS. 3A to 3D are diagrams for explaining processing in which the wireless communication terminal 1 sets connection to the second access point 102. FIG. 3A, while the wireless communication terminal 1 is connected to the first access point 101, the user of the wireless communication terminal 1 instructs the wireless communication terminal 1 to start connection with the second access point 102. give. Note that since the wireless communication terminal 1 is currently connected to the first access point 101, the profile of the first access point 101 is stored as a connection setting. The profile is stored in the storage unit 14. Until now, it is not a connection setting process but a steady state.

3 (b), when the control unit 10 proceeds to the connection setting process, the control unit 10 notifies the first access point 101 to disconnect in order to temporarily disconnect the connection with the first access point 101. After notifying the first access point 101 of disconnection, the control unit 10 starts connection with the second access point 102 and performs connection setting. Thereafter, a profile of the second access point 102 is created and stored in the storage unit 14. Thereby, the connection setting with the 2nd access point 102 is complete | finished. Next, in FIG. 3C, the control unit 10 notifies the second access point 102 of disconnection, and then reconnects with the first access point 101.

3 (d), a steady state is obtained by reconnection with the first access point 101. By creating a profile of the second access point 102, when the wireless communication terminal 1 goes out of the communication area of the first access point 101, the second access point 102 accesses the Internet 100. Connection continues.

FIG. 4 is a sequence diagram showing the connection setting process described above and each display timing in the connection setting process. 5A to 5D are diagrams showing display examples in the wireless communication terminal 1 at each display timing in FIG. The display examples shown in FIGS. 5A to 5D reflect the WLAN antenna picture as it is.

First, before connecting to the second access point 102, the display unit 12 of the wireless communication terminal 1 has an antenna indicating that it is connected to the first access point 101 as shown in FIG. A pict 200 is displayed. In addition, a message “Do you want to set the connection?” Is displayed on the display unit 12. The user (user) of the wireless communication terminal 1 who sees this message touches the “Yes” button when he / she wants to set the connection to the second access point 102. When the “Yes” button is touched, the control unit 10 of the wireless communication terminal 1 receives an instruction to set connection to the second access point 102 (step S1). Next, the control unit 10 stores information for specifying the first access point 101 currently connected in the storage unit 14 (step S2).

The control unit 10 stores information for specifying the first access point 101 in the storage unit 14, and then transmits a disconnection request to the first access point 101 (step S3). By this disconnection request, the connection between the wireless communication terminal 1 and the first access point 101 is disconnected. After disconnecting the connection with the first access point 101, the control unit 10 transmits a connection request to the second access point 102 through the WLAN communication unit 13 (step S4). When the connection response from the second access point 102 is received in response to the transmission of the connection request (step S5), the control unit 10 performs a connection setting process with the second access point 102 (step S6). . In this connection setting process, (1) encryption key sharing, (2) network identifier sharing, (3) device identifier sharing, and the like are performed. Note that there are standardized technologies such as WPS (Wi-Fi Protected Setup) for connection setting processing, and it is possible to share profiles by using them. In WPS, there are a PBC method (a connection method using a push button) and a PIN method (a connection method using an access code). In the case of adopting the PBC method, when the wireless communication terminal 1 desires connection setting for the second access point 102, the wireless communication terminal 1 makes a request to the second access point 102 at the same time as requesting the wireless communication terminal 1 to touch the button “Yes”. On the other hand, connection setting can be made by giving a request to start connection setting. When the PIN method is adopted, when the wireless communication terminal 1 wishes to set the connection to the second access point 102, an appropriate access code is given when the wireless communication terminal 1 is given a trigger by touching the “Yes” button. By inputting, connection setting becomes possible. The two examples described above are examples when the WPS method is used. In the present invention, if the profile can be shared appropriately, there is no restriction on the technical contents of the connection setting process.

After the connection setting process, the control unit 10 creates a profile for the second access point 102 and stores it in the storage unit 14 (step S7). On the other hand, the second access point 102 creates a profile for the wireless communication terminal 1 (step S8). Each process from step S3 to step S8 is performed during connection setting. By executing the connection setting process, as shown in FIG. 5B, the antenna picture 200 indicating that the first access point 101 is connected disappears from the display unit 12 of the wireless communication terminal 1. . Further, a message “Connection setting process” is displayed on the display unit 12. This message is displayed continuously until the connection setting process is completed.

When the profile of the second access point 102 is created in the wireless communication terminal 1 and the profile of the wireless communication terminal 1 is created in the second access point 102, the connection setting is completed. When the connection setting is completed, a message “Connection Setting Completed” is displayed on the display unit 12 as shown in FIG. The display unit 12 also displays an “L” character pict 201 indicating that the second access point 102 has been connected. The letter “L” 201 means that the connection setting between the wireless communication terminal 1 and the second access point 102 has been completed. In an environment where the first access point cannot be connected, Indicates that the access point can be connected.

After creating the profile of the second access point 102, the control unit 10 transmits a disconnection request to the second access point 102 (step S9). Thereby, the connection between the wireless communication terminal 1 and the second access point 102 is disconnected. After disconnecting the connection with the second access point 102, the control unit 10 reads information identifying the first access point 101 stored in the storage unit 14, and based on the information, the first access point 101 is connected (step S10). That is, a connection request is transmitted to the first access point 101 (step S11), and a connection response transmitted from the first access point 101 is received in response to this transmission (step S12). When receiving a connection response from the first access point 101, the control unit 10 enters a communication state with the first access point 101. In addition, when the control unit 10 enters a communication state with the first access point 101, as shown in FIG. 5D, the control unit 10 redisplays the antenna pict 200 indicating that it is connected to the first access point 101. To do.

As described above, according to the wireless communication terminal 1 of the present embodiment, when a connection start instruction with the second access point 102 is received from the user during connection to the first access point 101, the first access point 101 is disconnected, then connected to the second access point 102, connection setting processing is performed to create a profile of the second access point 102, and after the profile is created, the second access point The connection with 102 is disconnected and the connection with the first access point 101 is made again. Therefore, even after setting the connection with the second access point 102, the connection with the first access point 101 can be re-established without the user of the wireless communication terminal 1 being conscious.

In the wireless communication terminal 1 of the present embodiment, when the connection between the wireless communication terminal 1 and the first access point 101 is disconnected, the display of the antenna picture 200 is turned off. However, the antenna picture 200 is always displayed. You may make it make it. 6A to 6D are diagrams showing examples of the display. By thus displaying the antenna picture 200 at all times, it is not necessary for the user of the wireless communication terminal 1 to be aware of the state of the WLAN connection.

Also, in the wireless communication terminal 1 of the present embodiment, when receiving an instruction to perform connection setting with the second access point 102 in the connection setting process, information for specifying the first access point 101 is stored. After storing and creating the profile of the second access point 102, information for identifying the stored first access point 101 is taken out and reconnected to the first access point 101 based on the information However, these processes may be omitted and, instead, the profile of the second access point 102 may be stored with a lower priority than the profile of the first access point 101.

FIG. 7 is a sequence diagram showing a connection setting process when storing the profile of the second access point 102 with a lower priority than the profile of the first access point 101. In FIG. 7, steps that are the same as those in FIG. 4 are given the same reference numerals.

When the user of the wireless communication terminal 1 performs an operation for setting the connection to the second access point 102, the control unit 10 of the wireless communication terminal 1 issues an instruction for setting the connection to the second access point 102. Receive (step S1). Next, the control unit 10 transmits a disconnection request to the first access point 101 (step S3). By this disconnection request, the connection between the wireless communication terminal 1 and the first access point 101 is disconnected. After disconnecting the connection with the first access point 101, the control unit 10 transmits a connection request to the second access point 102 through the WLAN communication unit 13 (step S4). When the connection response from the second access point 102 is received in response to the transmission of the connection request (step S5), the control unit 10 performs a connection setting process with the second access point 102 (step S6). . In this connection setting process, (1) encryption key sharing, (2) network identifier sharing, (3) device identifier sharing, and the like are performed. Note that there are standardized technologies such as WPS (Wi-Fi Protected Setup) for connection setting processing, and it is possible to share profiles by using them. In WPS, there are a PBC method (a connection method using a push button) and a PIN method (a connection method using an access code). In the case of adopting the PBC method, when the wireless communication terminal 1 desires connection setting for the second access point 102, the wireless communication terminal 1 makes a request to the second access point 102 at the same time as requesting the wireless communication terminal 1 by touching “Yes” On the other hand, connection setting can be made by giving a request to start connection setting. When the PIN method is adopted, when the wireless communication terminal 1 wishes to set the connection to the second access point 102, an appropriate access code is given when the wireless communication terminal 1 is given a trigger by touching the “Yes” button. By inputting, connection setting becomes possible. The two examples described above are examples when the WPS method is used. In the present invention, if the profile can be shared appropriately, there is no restriction on the technical contents of the connection setting process.

The control unit 10 creates a profile of the second access point 102 after the connection setting process (step S7). On the other hand, the second access point 102 creates a profile for the wireless communication terminal 1 (step S8). After creating the profile of the second access point 102, the control unit 10 stores the profile of the second access point 102 in the storage unit 14 with a lower priority than the profile of the first access point 101 (step S13). ). Next, the control unit 10 transmits a disconnection request to the second access point 102 (step S9). As a result, the connection between the wireless communication terminal 1 and the second access point 102 is disconnected. Next, the control unit 10 scans connectable access points (step S14). If both the first access point 101 and the second access point 102 can be connected, the profiles stored in the storage unit 14 (the profiles of the first access point 101 and the second access point 102) are stored. Try to connect in order of priority from (Profile). In this case, since the profile of the first access point 101 has a higher priority than the profile of the second access point 102, the control unit 10 transmits a connection request to the first access point 101 (step S1). S11). In response to the transmission of the connection request, a connection response transmitted from the first access point 101 is received (step S12). When receiving a connection response from the first access point 101, the control unit 10 enters a communication state with the first access point 101.

Thus, by storing the profile of the second access point 102 with a lower priority than the profile of the first access point 101, it is possible to reconnect with the first access point 101 with priority. In other words, when scanning is performed on the first access point 101 and the second access point 102, if both can be confirmed, reconnection will be performed using a high priority profile. If the priority of the profile of the first access point 101 is lower than the priority of the profile of the second access point 102, the connection with the second access point is prioritized and the first access point 101 and Cannot reconnect. For this reason, by lowering the priority of the profile of the second access point 102 over the profile of the first access point 101, the first access point 101 can be reliably connected to the first access point 101. The access point 101 can be reconnected.

It is also possible to describe the connection setting process shown in the sequence of FIG. 4 or FIG. 7 by a program and store it in a storage medium such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory for distribution.

Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.

This application is based on a Japanese patent application filed on March 28, 2011 (Japanese Patent Application No. 2011-070511), the contents of which are incorporated herein by reference.

The present invention enables connection to the first access point without being conscious of the user of the wireless communication terminal if there is an environment in which the connection to the first access point can be established even after setting the connection to the second access point.
